United Kingdom: England

Still reeling from last year’s revelation that it will not play a role in the Unified Patent Court, the United Kingdom is waiting to see what its place will be in the post-Brexit European patent landscape. Despite the setbacks caused by the covid-19 pandemic, innovation continues to thrive and the patent profession has thus remained busy on both the contentious and non-contentious fronts. Artificial intelligence (AI) continues to be a focus, with more and more questions around the patentability of computer-implemented and AI-generated inventions arising as the technology advances. As elsewhere, national lockdowns have necessitated new working mechanisms and practitioners have adapted valiantly and creatively, with online hearings running smoothly and many commentators suggesting that they may continue post-pandemic. In August 2020 the Supreme Court issued its decision in the seminal Unwired Planet and Conversant cases; the ruling represented a major victory for SEP owners, although the long-term effects for SEP and FRAND-related disputes on a wider scale remain to be seen.

Alembia Intellectual Property Ltd

Cheshire-based Alembia IP devises robust patent prosecution strategies, largely – though not exclusively – for pharmaceutical companies. Lead partners Lucy Padget and Nonny Jones have invaluable first-hand experience of the innovation process from their time in-house at AstraZeneca, and since founding the firm have become trusted guides for everyone from solo inventors to corporations from the United States and China. “They have a high-level command of the science, a deep understanding of patent law and strong commercial awareness.” Padget “is smart and pragmatic, with a good sense of the bigger picture; while Jones “is extremely knowledgeable, works quickly and efficiently, and keeps a close eye on all procedural aspects in the relevant territories”.

Allen & Overy LLP

Despite some significant personnel losses over the last two years, Allen & Overy remains on top of its game. It has been representing Huawei in its hotly debated dispute with Conversant under the watchful eyes of Mark Heaney, Neville Cordell and Mark Ridgway. “Skilled operator” Heaney is “exceptionally intelligent and knowledgeable”; while the “diligent and detail-oriented” Cordell likewise “has excellent knowledge of the law – you can count on Neville to make sure any errors are picked up on”. Ridgway is hailed as “one of the best patent litigation tacticians in London”: “If Mark were not featured in the IAM Patent 1000, his omission would be startling.” With a facility for both telecommunications and life sciences disputes, he “maintains a partner-level overview of cases while rolling up his sleeves and getting to grips with client needs”. Anchoring the life sciences side is Marjan Noor, who has been busy acting for Bayer in patent infringement and revocation proceedings relating to a veterinary injection product. Her degree in medical sciences and pharmacology grants her keen technical insight. On the transactional front, Jim Ford and Nigel Parker have all the answers – global life sciences co-head Ford recently advised Circassia Pharma on the termination of a development and commercialisation agreement with AstraZeneca; while Parker’s highlights include assisting GlaxoSmithKline with a collaboration agreement in the cutting-edge area of mRNAvaccines.

Anderson Law LLP

When it comes to getting high-rolling, IP-rich transactions across the line, few firms do it better than Anderson Law. The last year saw it broker a range of technology transfer agreements for world-leading academic institutions, including City, University of London; and a set of R&D agreements for university spin-out Zoe Global in relation to its covid-19 symptom study app. Universities and technology-driven enterprises look to Lisa Allebone for crisp, finely drafted contracts that effectively commercialise their patents. The physics PhD has a wealth of biotechnology and pharmaceutical insight. Also covering the life sciences is managing partner and namesake Mark Anderson, who is distinguished not just for his stellar work record, but also for the award-winning course he runs annually for IP transactional lawyers at University College London. Making his debut in the IAM Patent 1000, IT specialist Paul MacLennan is a fan favourite of multinationals and leading UK universities, and “brings credibility, capability and competence to any team, spending time briefing on the various possible approaches”.

Appleyard Lees 

Appleyard Lees is “a professional, reliable and highly competent firm, which leads clients to make good decisions about their patent applications. The quality of its work is of a high standard, requests are turned around very quickly and there is always somebody on the other end of the phone to coach you through complications”. With a network of strategically located bases in Cambridge, Manchester, Leeds, Halifax and the Biohub at Alderley Park, Cheshire, it has positioned itself at the heart of industry and innovation. Its overall share of granted EPO patents currently stands at an impressive 2.9% and it is known for the longstanding relationships it forges with its household-name clients such as Walmart.  Geneticist Simon Bradbury recently provided comprehensive patent support to BenevolentAI, Europe’s largest privately owned AI company. “Simon has a solid strategic approach and his in-house experience in large companies gives him a good understanding of business requirements. He can step in at a very early stage, facilitating open discussion in order to get things done.” Also on board is Bobby Smithson, who comes with academic credentials in both chemistry and law; he heads up the firm’s medical devices practice and assists companies such as PPG Industries and Smith & Nephew. “Bobby not only demonstrates a deep understanding of the legal and procedural aspects, but also an uncanny grasp of the technology. He provides indispensable guidance at every juncture and does so in a characteristically personable and approachable manner.”

Arnold & Porter

Complex transactions involving state-of-the-art technologies are meat and drink to the IP group at Arnold & Porter Kaye Scholer: as examples, in 2020 it advised both AstraZeneca and Pfizer on their covid-19 vaccines. Running point for both was Ewan Townsend, who made partner in January 2020 and is a walking encyclopaedia of pharmaceutical regulatory know-how. “Ewan’s work is always outstanding and his commercial acumen is excellent. He is a pleasure to work with and extremely responsive.” His counterpart on the disputes side is Beatriz San Martin, another life sciences expert who has been tasked with building out the firm’s contentious IP offering. She recently acted for Sandoz in a protracted, high-profile SPC invalidity case.

Barker Brettell LLP

Established in Birmingham in 1850, the venerable Barker Brettell dispenses sophisticated prosecution counsel and patent strategy, especially within the high-technology, automotive and aerospace sectors. It has an intuitive grasp of the needs of universities and their spin-outs, and complements its domestic workload with a slew of overseas instructions, particularly from the United States. With over 30 years in the game, John Lawrence heads the automotive and aerospace sector groups; computer-implemented inventions and electronics briefs for major players such as HP and Ericsson are further strings to his bow. On the life sciences side, Jennifer Atkinson captains both the biotechnology group and the university sector team. The astute IP strategist and EPO representative has been busy managing portfolios for the universities of Nottingham and Oxford; helping an academic start-up which went on to secure £1.5 million in funding; and advising various universities on covid-19 technologies.

Beck Greener

Despite the trials of the pandemic, IAM Patent 1000 debutant Beck Greener enjoyed a red-letter year in 2020. An ever-growing litany of global industry leaders seek it out for smart patent portfolio management that can withstand the test of time: indeed, several of its client relationships have now passed the 40-year mark. On the oppositions and appeals front, the group has enjoyed an enviable success rate of over 85% for two consecutive years and is regularly entrusted with some of the most complex issues on the market. Leading the practice is Avi Freeman, who also heads up the electronics, physics and mechanical engineering teams. He speaks the language of software clients and is a percipient adviser on unregistered designs issues. Chemistry ace Anna Hatt matches portfolio management acumen with skill in oppositions before the EPO; she is especially valued by clients from the Nordic region.

Bird & Bird LLP

While Bird & Bird’s English contingent is a vital cog in the firm’s global machine, it is also mightily impressive in its own right. With 32 of its lawyers boasting scientific qualifications, the group can easily parse the most technically challenging matters. It “has a great understanding of client needs and expectations, and the ability to communicate simply and effectively”; and it “provides prompt support even when under time constraints”. Co-heading the IP group are Katharine Stephens and Robert Williams. Stephens has a flair for cross-border litigation and the development of pan-European patent enforcement programmes, and increasingly applies her robotics knowledge to advise on electronics and AI issues. Williams is an adroit handler of multi-jurisdictional disputes whose managerial prowess has led to his involvement in the creation of project management tools. Meanwhile, Jennifer Jones, Neil Jenkins, Mark Hilton and Eleanor Root have the life sciences on lock. Qualified in molecular biology and genetics, Jones knows all the right plays when it comes to global patent litigation strategy; while consummate cross-border litigator Jenkins is an expert in regulatory data exclusivity and SPC issues. Hilton co-heads the international life sciences and healthcare group, comprised of over 130 Bird & Bird lawyers across the globe; and IAM Patent 1000 newcomer Root brings valuable insight from recent secondments at two pharmaceutical multinationals. Patrick Kelleher is a vital ally for Israeli biotechnology start-ups that find themselves embroiled in European patent litigation; while Morag Macdonald is “not only a very seasoned litigator, but also exceptionally strong at developing and executing international litigation strategies”. She recently acted for AB InBev in a commercially crucial High Court patent revocation case against Heineken in relation to polymer packaging technology. On the telecommunications side, the group is equipped with Richard Vary and Jane Mutimear. Vary was previously vice president and litigation head at Nokia, and recently represented the telecommunications giant in mediation against Daimler and in litigation against IPCom. “Few people have Richard’s level of knowledge of the most pressing issues. He has worked on many of the major cases in Germany, the Netherlands, Italy and the UK, as well as the US and China, so he understands how the major jurisdictions fit together and how to coordinate litigation around the world.” Mutimear litigates across the IP spectrum and also assisted in the development of Pattern, Bird & Bird’s patent portfolio intelligence product. Transactional nous is supplied in abundance by Sally Shorthose and Tom Snaith. Shorthose is a life sciences specialist whose licensing advice is informed by her time as legal director of Novartis UK; while Snaith has a technical background in chemistry and guides private equity firms and major corporations through IP-heavy M&A deals, spin-outs, restructurings and joint ventures. “Tom is responsive, pragmatic, commercially minded and highly regarded by his in-house colleagues.”

Boult Wade Tennant LLP 

Boult Wade Tennant is one of the country’s foremost prosecution shops, having filed more than 2,000 patent applications and attended some 100-plus EPO hearings in 2019. With 66 patent practitioners on deck, 27 of whom hold PhDs, it has the technical dexterity to handle instructions across all industries: in the past year alone, it assisted contract development and manufacturing organisation the Almac Group with global patent strategy; dispensed strategic advice to Caterpillar Inc; and appeared in oppositions on behalf of medical technology and healthcare giant Abbott. Oliver Rutt, Edward Ronan, Simon Kahn, Daryl Penny, Tessa Bucks, and James Short are among those making their debuts in the IAM Patent 1000 this year. Rutt is “client focused and conscientious, but also has a strong grasp of technology”. “His understanding of assembly materials, alloys and sintering powders sets him apart from his peers. He works with a sense of urgency, is very prompt when it comes to deadlines and is extremely meticulous.” Vaccinology PhD Ronan likewise earns warm plaudits: “His work is thorough, strategic and timely, and he works closely with clients in assessing different strategic approaches and offering valuable suggestions.” Another PhD, this time in electrical and electronic engineering, Kahn “has strong, adaptable technical skills in drafting, is highly knowledgeable on the law and provides solid strategic thinking on prosecution”. Working alongside him in the high-technology and electrical group, Penny is an experienced physicist who “displays the highest calibre of professionalism – he handles matters with the utmost care and competence, and performs technically complex work in a timely way”. Bucks heads the engineering and designs group and provides “outstanding patent drafting, EPO representation and advisory services”: “She has a deep understanding of the patent technology and presents ideas and arguments in a clear, coherent manner.” Computer science PhD Short on the other hand is “always attentive and explains all routes of action in great detail”: “Responsive, prompt and hospitable, he provides proactive feedback, allowing rights holders to further refine their approach and extract added value from their patents.” The above practitioners join a cadre of Boult Wade Tennant attorneys who make their return to the rankings for 2021. On the biotechnology and life sciences side, Nina White and Matthew Spencer are the names to note. White has a doctorate in molecular biology and focuses on therapeutic antibodies. Heading up the Cambridge biotechnology and life sciences group, Spencer is “extremely quick and thorough in familiarising himself with the patents in question and the prior prosecution details”: “His strategy, technical competence, diligence and eye for detail are exemplary.” At the helm of the high-technology and electrical group is chartered physicist Nick McLeish, who covers all angles both when acting before the EPO and when supporting in litigation: “Even in the most difficult situations he finds a solution, thanks to his creativity and technological understanding.” He is joined on the electronics side by physics PhD Jonathan Palmer, whose analysis of research programmes and advice on patentability are unerringly on point. Chemical and materials group head Adrian Hayes is a tireless advocate in oppositions and appeals, appearing in more than 20 in an average year. Working alongside him is materials science PhD Rohan Setna, who also knocks it out of the park in contentious scenarios: he recently prevailed for Koninklijke Dowe Egberts in a coffee-machine-related opposition against Nestlé. IP all-rounder Tony Pluckrose dives into the nitty-gritty of medical device, aerospace and oil industry engineering patents, while maintaining an equally successful trademark practice.

Bristows LLP

Bristows has made UK patent litigation its own: as of September 2020, it featured in some 26 of the 91 pending cases at the Patents Court. It consistently hammers out the right results in fraught disputes in virtually every industry, which often involve parallel proceedings across Europe and the United States. Highlights in the past 12 months include a headline-grabbing FRAND suit for ZTE and global patent litigation over beer dispensing systems for Heineken. Involved in both is patent litigation co-head and “strategic guru” Andrew Bowler, an “experienced patent litigator who makes life difficult for the other side”: “He is outstanding at picking up on the decisive issues and presenting sharp solutions.” Leading the group alongside Bowler is Myles Jelf, who has also been busy on the ZTE piece, as well as with another crucial FRAND case on behalf of IPCom against companies including Lenovo, HTC, Xiaomi and Vodafone. Working alongside him on the latter mandate is electronics and mechanics litigator Richard Pinckney: “He is sharp, focused and has a real feel for how best to direct a case, achieving excellent results in difficult and demanding time constraints.” Also technically proficient is solicitor-advocate James Boon, who holds a PhD in optoelectronics and handles disputes in fields from 3G to oil and gas. Together with Pinckney, he recently tackled a set of FRAND and SEP-related actions on behalf of Philips. On the life sciences front, the group has dispatched multiple briefs for Novartis in recent months, including a paediatric extension dispute led by Brian Cordery and a patent revocation action led by Gemma Barrett. A favourite of pharmaceutical innovators, Cordery is described by overseas colleagues as “definitely one of the guiding lights of the English patent litigation space”. Barrett – who has an academic background in molecular and cellular biochemistry – “takes a pragmatic and highly effective strategic approach, keeps on top of the science and is a strong team manager”. Further contentious firepower in the life sciences comes from of Dominic Adair, Gregory Bacon, Robert Burrows and Liz Cohen. With a technical background in biology, Adair is “responsive, highly motivated and invests significant time and effort in order to understand the technology”. Bacon is a “great patent litigator who is confident with the technical side of a case, but also has a good tactical legal brain”. “Particularly adept at the science”, Burrows has additionally “mastered the strategic aspects of UK and multi-jurisdictional patent disputes”. Cohen also has a technical background and has been assisting Italian pharmaceutical originator Chiesi Farmaceutici with its patent enforcement strategy: “Once a client works with Liz, they don’t tend to go anywhere else. She has a clear strategic overview of a case, steers litigation in a direction consistent with commercial objectives, and strikes exactly the right balance between pragmatism and aggression.” After a 35-year career during which he appeared in more than 100 patent cases, senior statesman Edward Nodder now manages the group’s relationships with Japanese clients and contacts. The patent transactions team includes Matthew Warren, Claire Smith and Richard Dickinson. Commercial IP head and physicist Warren is great at getting deals involving new technologies inked in all industries. The life sciences is a forte for Smith: “Claire understands the practicalities and legalities of licence, M&A and collaboration agreements, picks up on international issues quickly and is a pragmatic counsellor.” With an academic background in biochemistry, Dickinson understands both the technical and legal sides of the deals he shepherds to close.

Browne Jacobson LLP

The brands team at full-service Browne Jacobson is relied upon by companies around the globe for smart portfolio management, trademark litigation, licensing and strategic advice, and also offers related sponsorship and advertising services. Leading the line is IP and commercial head Declan Cushley, who dispenses strategic brand protection counsel to the likes of Lloyds Banking Group. His crew of high-quality professionals includes Bonita Trimmer and Giles Parsons. Brands and designs disputes expert Trimmer is described as “practical, reasonable, but willing to be tough when necessary”, while Parsons’ broad contentious practice covers trademarks, patents, copyright, designs, passing off and confidential information. Also on hand are Cerryg Jones and Mark Daniels – Jones has made regular appearances in brands and designs disputes in the Supreme Court and High Court during his 20 years in the game; while Daniels supports a thriving patent practice with a raft of trademarks and designs work in the automotive sector.

Carpmaels & Ransford LLP 

With an A-to-Z patent offering, Carpmaels is the full package for market-leading innovators. Close collaboration between its patent attorneys, solicitors and barristers is a hallmark – and one which leads to satisfyingly well-rounded representation. The firm’s EPO oppositions practice is worthy of special mention as one of the best around. Credit in this regard is due to many, including Hugh Goodfellow, James Warner, Cameron Marshall, Edward Oates and Harvey Adams and Daniel Wise who – together with Mark Chapman – form the backbone of a world-class life sciences practice. Goodfellow gives “clear and precise advice” and has a “talent for resolving matters without recourse to expensive litigation”. Warner provides strong leadership to the pharmaceutical team and to clients such as Johnson & Johnson, whose Zytiga prostate cancer treatment he has protected in Europe for the past decade. Hailed for his forward-thinking approach, Marshall has been putting in a sterling performance for Jazz Pharmaceuticals of late; while Oates is a foremost authority on SPC law. A fierce advocate whose strategies are perfectly suited to complex litigation with parallel proceedings, Adams was recently instructed by Biogen to represent it in the neuroscience field. Wise on the other hand is a protein therapeutics, vaccine technology, and medicinal chemistry ace who has recently been called upon by LEO Pharma to act in a range of oppositions and draft complex filing strategies in relation to its “Picato” product. The ensemble’s top pure-play biotechnology expert, Chapman recently linked up with transactions ace Jake Marshall to help Harbour BioMed execute a patent and know-how licensing agreement with Abbvie to commercialise an antibody for the treatment of covid-19 – a great example of the inter-practice cooperation that is so essential to the firm’s success. Marshall “communicates with crystal clarity and focuses on the key issues. His work is extremely thorough”. Portfolio curator Paul Bettridge steps in when companies need to protect innovations in crossover areas such as electrochemical molecular diagnostics and bioelectronics; while Christopher Tunstall’s 30 years at the patent coalface inform his strategic management of vast portfolios for the likes of Johnson & Johnson. Chemist Susan Kirsch maintains a busy and diverse EPO oppositions practice and recently appeared in several proceedings on behalf of Ethicon in relation to its portfolio of medical device patents; while John Brunner focuses on IT and telecommunications, and recently took on the guardianship of Barclays Bank’s burgeoning fintech portfolio. On the litigation side, Ian Kirby has been racking up the wins for over 25 years and stands out for his inspiring team management and big-picture thinking both in and out of the courtroom. The similarly experienced David Wilson knows both the life sciences and telecommunications fields like the back of his hand; his practice is further enhanced by an academic and industrial background in chemistry. Also litigating within the life sciences realm are Camilla Balleny and Jennifer Antcliff: Balleny has been leading on the UK component of a pan-European patent dispute on behalf of Ceva Santé Animal Health; while molecular biology PhD Antcliff is a newcomer to both the IAM Patent 1000 and the Carpmaels partnership, with valuable in-house insight from a stint at Allergan.

Charles Russell Speechlys LLP

The flourishing IP group at full-service commercial firm Charles Russell Speechlys continues to make an impression, thanks to the results it secures in big-ticket litigation and transactional negotiations. It cultivates longstanding relationships with clients – which move in fields from pharmaceuticals to engineering and construction – and gets to know every aspect of their business, which translates into bespoke, commercially optimised solutions.

Cleveland Scott York

Whether prosecuting UK and European patent applications for its legion of direct clients or advising on infringement and validity issues, the team at Cleveland Scott York has both the technical and legal chops to get the job done quickly and to the highest standard. While widely capable, it has a real affinity for the needs of the technology transfer arms of academic institutions. Having previously worked in-house at Pfizer, pharmaceuticals don Adrian Bradley “operates in a highly collaborative manner and has good insight into the value of the technology he is handling”; he is “a valued adviser not only in the UK, but also in challenging jurisdictions overseas”. Also receiving high praise is materials science and engineering maven Fraser Brown: “Fraser is incredibly knowledgeable in his field, which instils great confidence in clients, and has an affable, thoughtful manner. He is highly responsive, can unpick knotty issues and advises with a real-world commercial view.” “Outstanding” patent attorney Tom Faulkner is “always responsive and attentive”, attests one client of 10 years’ standing. On the automotive side, Andrew Mackenzie communicates almost telepathically with R&D teams as a former design engineer for Jaguar Cars; he recently helped Federal-Mogul Powertrain to protect its cleantech systems for hybrid and battery vehicles.


Since its head-turning merger in 2017, CMS has gone from strength to strength on both sides of the contentious/non-contentious divide. The calibre of its clientele bears this out: for example, Microsoft has enlisted it for a significant volume of its original drafting work; while Microsoft-owned LinkedIn also looks to it for smart portfolio management. Taking care of both instructions are Helen Wallis and Rachel Free. Wallis is a computer hardware and software and telecommunications specialist who is “responsive, generous with her time and good at communicating with US counsel”; while AI sage Free is “efficient and precise in pinpointing issues at the heart of complex IP matters”. In the life sciences, the group has appeared in a series of EPO oppositions for Kymab under the hawkish eyes of Robert Stephen and Jane Hollywood. Leading the patent attorney group, molecular genetics PhD Stephen provides prescient counsel relating to vaccines, antibodies and antibody protection, and SPCs. Also holding a PhD – this time in plant sciences – Hollywood “has a huge amount of technical expertise. She always explains everything extremely thoroughly and gives a good overview of all the key factors”. Fellow life sciences ace Jane Evenson “comes up to speed quickly and thoroughly on the technology, and can always be counted on to be prepared and offer insightful, commercially relevant guidance”. On the contentious front, the firm recently secured a remarkable damages award in the tens of millions for Sandoz in litigation against Napp Pharmaceutical Holdings. The win was orchestrated by patent litigation head Gareth Morgan, together with Sarah Innes and Caitlin Heard. Morgan – who is as comfortable in the courtroom as at the deal table – is intimately familiar with the healthcare sector, with a fine-grained appreciation of SPC issues and pharmaceutical regulatory law. Innes previously worked in-house at a major pharmaceutical company and has a “great understanding of the generics market”; while Heard splits her time across the pharmaceutical and high-technology sectors, and acted in one of the first SEP and FRAND disputes ever heard in the English courts.

Cooley LLP

Intellectual property is a central plank at full-service US outfit Cooley, whose 110 patent professionals work hand in glove with colleagues in other departments to provide a reassuringly holistic service. While disputes are not beyond its remit, the London team garners particular acclaim on the transactional side – not least thanks to the efforts of life sciences specialists John Wilkinson and Nicola Maguire. Wilkinson’s knowledge of IP, regulatory and antitrust law knows no bounds – “he finds imaginative solutions and has a deep understanding of the science”; while Maguire makes light work of IP-heavy deals with international components. The main draw for prosecution instructions is Colm Murphy, who has spent more than two decades crafting futureproofed IP portfolio strategies and acting in EPO oppositions and appeals for major biochemical, pharmaceutical and medical device companies.

Covington & Burling LLP

Covington & Burling is home to an elite transactional patent offering: competitors note that it “jumps out of the list as one of the best in the market”. Making their mark are Lucinda Osborne, Daniel Pavin and Morag Peberdy, all of whom have life sciences acumen in spades. Osborne is a smooth broker of technology transactions and collaboration agreements within a cross-border context. Pavin focuses on digital innovation in the life sciences space, having previously worked in industry as a computer programmer. Meanwhile, ambidextrous solicitor-advocate Perbedy draws on her background as a biologist to cover all bases on both the non-contentious and contentious sides.

D Young & Co LLP 

D Young & Co’s 50-strong team of patent attorneys and solicitors meets and exceeds the needs of a slew of household-name clients: Boehringer Ingelheim Animal Health USA and Sony have lately looked to it for filing strategies; while Teva Pharmaceuticals and Nestlé are among those it is representing in EPO oppositions. Leading on the Boehringer Ingelheim matter are Garreth Duncan and Zöe Clyde-Watson. Duncan has broad horizons, having previously worked in Pfizer’s European and US patent departments, and a knack for obtaining SPCs. Organic chemistry PhD Clyde-Watson “provides reliable advice and strategy, is very knowledgeable on EPO patent law and practice, and produces work product of a quality rarely seen”. Other pharmaceutical mavens at the firm include Tamara Milton, Charles Harding and Neil Nachshen. The “proactive” Milton has “in-depth knowledge of worldwide patent prosecution, which she communicates effectively”; while oppositions ace Harding “is always on top of developments and his ideas for patent strategy are always creative”. “Excellent EPO advocate” Nachshen is assisting Teva and has also supported a host of pharmaceutical companies both in private practice and in-house during his 20-year career. Likewise acclaimed in the life sciences is Simon O’Brien, who blends “comprehensive knowledge of scientific matters” with “the ability to mesh patent prosecution strategy with technological developments”. His technical specialism in pharmaceutical chemistry is shared by Kit Wong, who holds a PhD in the subject: “Kit provides highly timely support, with deep technical insight and a clever eye for the nuances of European patent prosecution. She is among the best of the best.” Also with a PhD – this time in organic chemistry – is patent attorney litigator and EPO oppositions sharpshooter Kirk Gallagher, a skilled coordinator of contentious proceedings across Europe and the United States. Fellow patent attorney litigator Anthony Albutt heads up the mechanical group and is handling the set of Nestlé oppositions. Playing point for Sony is “solid and reliable” electronics expert Jonathan Jackson, who previously worked in the multinational’s IP department. With a background in electronics and a PhD in high-energy physics, Nicholas Malden is a valued adviser to companies across Europe, the United States and the Far East in fields such as processor design and computer-implemented technologies.


Dehns is a potent player in the European patent prosecution space: “It handles all technologies, is particularly good in EPO oppositions and demonstrates timeliness, responsiveness and value for money.” The storied group has been a fixture on the scene for over a century and now has eight offices across the United Kingdom , Germany, and Norway; its counsel comes underpinned with advanced technical know-how, as 30% of the team hold PhDs. Physicists and patent attorney litigators Christopher Davies and Robert Jackson are the stars of the engineering group. Davies has been with the firm for more than 40 years and has a level of experience in EPO oppositions that few can match. Jackson heads up the litigation practice, while also undertaking original drafting for a diverse range of clients across the United Kingdom, the United States and Scandinavia. Life sciences concerns have molecular biologist Philip Webber on speed dial: he plays a crucial role in shaping the IP strategies of pharmaceutical and biotechnology start-ups, SMEs and university spin-outs. In recent years, CRISPR-based inventions and recombinant vaccines have become an increasing focus of his practice. New to the practice is veteran litigator Paul Harris, who made a high-profile move from Venner Shipley in 2021. The solicitor has been in the game for over 35 years and has developed a thriving confidential information practice alongside his IP work.


With 850 dedicated professionals on deck, full-service Dentons has all aspects of IP law down cold and the UK contingent reflects this in microcosm: a cradle-to-grave patent service ensures that it can tackle almost any mandate thrown its way. Captaining the European patent prosecution and opposition practice is Justin Hill, who has recently been busy managing Raytheon’s patent portfolio; devising filing strategy for new client Tesla; and appearing in oppositions and appeals for medical devices leader Dexcom. Clients value “his strategic and commercial opinions in the patent process, as well as his technical strength”. Running the show on the contentious front is global IP co-head and deputy district judge Campbell Forsyth, who has lately gone out to bat for Czech generic drug manufacturer Zentiva in an SPC-related dispute against Gilead.

DLA Piper

High-stakes litigation and high-rolling transactions are all in a day’s work for the energetic patent practitioners at DLA Piper. As part of a phalanx of 130-plus patent litigators worldwide, its courtroom dynamos shine in the cut and thrust of complex cross-border disputes. The firm scored a coup in 2019 by bringing Deborah Bould on board: “Deborah listens to and cares about what her clients want to achieve, and is great at networking with the right people from across (or even outside of) her firm.” Combining “a great eye for detail with admirable brevity and practicality”, she puts in winning performances in SEP actions, especially within the Internet of Things field. Holding things down in the life sciences is Richard Taylor, who has defended myriad pharmaceutical giants to the hilt during his 20-year career.


Traditionally a go-to for precision prosecution, EIP is increasingly making incursions in the contentious space – and the landmark victory it recently secured in the Unwired Planet/Conversant litigation will only serve to further elevate its standing on the market. The architect of this win was litigation head and “huge name” Gary Moss – a “terrific litigator” and “leading light who really knows his stuff”. Working alongside him on the brief was Andrew Sharples, a dual-qualified solicitor and European patent attorney whose FRAND expertise is matched by prowess in the life sciences: he heads the group dedicated to this discipline. The firm is also acting for Conversant in complex litigation against Apple, spearheaded by solicitor-advocate Robert Lundie Smith. With a PhD in chemistry/chemical physics, he is ideally qualified to handle technically challenging cases. Also making their mark on the solicitors’ side are Kathleen Fox Murphy, who has a complete command of issues as varied as SPCs and FRAND licensing; and Matthew Jones, an equally dexterous practitioner with unparalleled pharmaceutical insight from a biotechnology PhD and a stint as senior counsel at Teva. Meanwhile, the firm maintains its burnished reputation for prosecution: “EIP gets the details right and interacts efficiently with inventors, forming a collaborative working team with them to consider, build or reject ideas. It presents patent law and its implications clearly, helping clients to make well-informed commercial and strategic decisions.” Heading up the digital practice group is founder Jerome Spaargaren, a shrewd coordinator of global patent prosecution and enforcement programmes in fields as diverse as machine learning, data processing, cloud computing and unmanned vehicles. Other electronics and software mavens include Matt Lawman, Laurence Brown and Heather McCann. Roles in-house at BT and Hewlett-Packard have given Lawman a bird’s-eye view of the innovation process; while Brown is an adroit portfolio curator whose illustrious clientele includes the likes of Sony, Sonos Inc and Morphy Richards. McCann previously served time at a major telecommunications group and has lately been filing a stack of patent applications on behalf of VISA. In the life sciences, synthetic organic chemistry experts Gareth Probert and Darren Smyth are the names to note. Probert has appeared in more than 250 opposition and appeal proceedings, and has prevailed against the odds in many; while Smyth likewise has a pristine contentious track record and is “intelligent, detail oriented and articulate, while also being affable and an absolute pleasure to work with”.


The venerable Forresters has provided a premier prep and pros service since 1884 and today maintains laser-focused on growth, as reflected in the arrival of new partners and the establishment of new UK branch offices in recent years. A thriving Munich outpost, manned by Matt Barton, ensures that it can offer a truly European service, advising companies from across the continent on filing strategy as well as niche issues such as SPCs and plant variety rights. The group’s technically savvy attorneys have long walked the halls of the EPO and make frequent appearances before its Opposition Division and Boards of Appeal. One especially esteemed EPO representative is Jonathan Gowshall, a “pragmatic advocate who achieves remarkable successes for clients”.

Freshfields Bruckhaus Deringer LLP

Since bringing on board former Arnold & Porter partner Christopher Stothers two years ago, the patent group at Freshfields has seen its profile skyrocket. Litigations and transactions are its bread and butter, particularly in the high-technology and life sciences industries. Stothers is a consummate tactician in cross-border patent disputes and EPO oppositions, and teaches on IP and competition law at University College London. Colleague Laura Whiting made the move with him from Arnold & Porter. A qualified solicitor-advocate with a background in chemistry, she relishes the complexities of technically dense patent and SPC suits; she also has a facility for disputes at the intersection between IP and competition law, especially those with a FRAND angle. “Laura is a top-quality solicitor with excellent advocacy skills, technical understanding, drive and passion for her work.” Anchoring the transactional end are David Brooks and Giles Pratt – IP commercialisation maven Brooks is well-placed to tackle complex M&A briefs and has experience working in London, New York and Singapore, while Pratt heads up the transactions group and is one of the brains behind the firm’s cutting-edge Freshfields Digital platform.

Gill Jennings & Every LLP

One of the pre-eminent prosecution outfits not just the United Kingdom, but in Europe, Gill Jennings & Every has featured in over 1,100 EPO oppositions since it was established. “It perfectly combines the technical and legal sides. All its people are easy and pleasant to work with – they quickly grasp the subtleties of new inventions and they come with a huge network of worldwide associates.” Its client roster includes De La Rue, for which Heather Scott and Robert Skone James have both been acting in a set of oppositions over the last 12 months relating to the transparent windows on polymer banknotes. Physicist and engineer Scott “understands the unique requirements of clients’ businesses, presents arguments clearly and concisely, and is always prepared for any scenario”. Skone James’s career recently reached the 42-year mark and he serves as the incumbent chair of the firm: “He provides superb technical insight, advice and support at every stage of the process.” Filing and defending the patents of insulation manufacturer Rockwool – a client of the firm for more than half a century – is Lucy Samuels, who has appeared in a staggering 580 opposition and appeal hearings during her 27-year career; her deep chemical engineering knowledge and fine-tuned commercial sense make for a winning combination. The sprawling patent portfolio of software giant Oracle is safe hands with Peter Arrowsmith, a computer-implemented inventions expert who also understands how best to nurture start-ups. Tending to the needs of Mylan is chemist Arnie Clarke, who has also handled countless high-profile briefs for the likes of Procter & Gamble, Teva and AstraZeneca. Pharmaceutical players are also ably catered to by John Jappy, a “deep thinker and analytic problem solver with a strong grasp of IP strategy and a commitment to getting things done”. “He is sensitive to the problems encountered by emerging companies, and his approachable and friendly demeanour makes for a productive working rapport.”

Gowling WLG

The UK contingent of global force Gowling WLG continues to forge ahead on both sides of the contentious/non-contentious divide, with competitors singling out its “strong and remarkably business-friendly team”. Many precedent-setting decisions across the industry spectrum bear its fingerprints, particularly in relation to FRAND licensing. Alexandra Brodie is “an impressive and efficient professional and a worthy courtroom opponent who is doing a lot of strong work, especially in the FRAND space”. Similarly active in this sphere is Huw Evans, who joined the firm two years ago together with the commercially minded, no-nonsense Jonathan Ball; the versatile pair have the high-technology and life sciences sectors locked down. Collaborative and pragmatic, Evans has built up a thick address book of international contacts; while forensic biochemist Ball is cultivating a growing fintech specialism. Another technical renaissance man is Jamie Rowlands; he previously headed the firm’s China office and today puts in polished performances in cross-border disputes for players from as far afield as the United States, Japan and Africa. Molecular biologist Paul Inman also has an international outlook from the many high-profile pharmaceutical disputes he has handled globally. A “leading light” and “senior statesman of the profession”, Gordon Harris is hailed by one European colleague as “the best patent litigator in the world”; he is known for his ground-breaking methods, which have inspired major changes to the law throughout his 30-year career. Transactional whizz Patrick Duxbury captains the life sciences practice group and regularly negotiates transformative global deals: he recently advised AstraZeneca on its landmark collaboration agreement for the development and distribution of the Oxford covid-19 vaccine.

Herbert Smith Freehills LLP

Business-minded solutions to complex commercial problems that ensure maximum impact with minimum fuss are the calling card of Herbert Smith Freehills. The patent group has acted in some of the most hotly contested disputes around for a litany of leaders in IP-heavy industries. As an example, it recently represented Genentech, F Hoffmann La-Roche and Roche Products in multi-jurisdictional patent litigation against Pfizer relating to blockbuster cancer drug Avastin. Taking the lead on this were SPC expert Sebastian Moore and qualified biologist Sophie Rich, who are both known for their “client-oriented thinking, well-thought-through legal advice and sense of urgency”: “They proactively coordinate with local counsel, providing an easily digestible overview so that the client can concentrate on strategic decisions.” Also operating in the pharmaceutical space is fellow SPC maven and solicitor-advocate Jonathan Turnbull, a biochemistry PhD who has directed cross-border litigation programmes across 40 jurisdictions. Other solicitor-advocates at the firm include Andrew Moir and Mark Shillito. FRAND licensing is a forte for Moir, whose high-technology patent litigation practice is underpinned by qualifications in physics; while Shillito is a trusted guide for titans such as Apple, Vodafone and Eisai.

HGF Ltd 

New office openings and acquisitions taking place across Europe at dizzying pace reflect HGF’s lofty ambitions – as do the statistics: it was the 15th largest filer at WIPO in 2019. From 21 bases across Europe, it tends to all non-contentious needs of its diverse clientele, with emerging areas such as AI and CRISPR technology an increasing focus. EPO oppositions are the metier of chemist and oppositions and appeals head Chris Moore; he recently acted for Philip Morris International in a series of e-cigarette related oppositions alongside fellow chemist Hsu Min Chung. Chung’s scientific acumen is easily applied in a vast range of fields and is matched with valuable insight from time spent in-house at a world-leading oil and gas company. Another persuasive EPO advocate is engineer Jennifer Uno, who can get her head around almost any mechanical or medical device; a stint at a patent attorney firm in Osaka gives her an edge when collaborating with Japanese clients. Fellow engineer Lucy Johnson is “pragmatic, capable, knowledgeable and fosters enjoyable working relationships”. “Thanks to her advice and expertise, clients’ IP strategies are a living thing – constantly under review and revision as businesses evolve. She works to understand not only the technology, but also the commercial goals at the centre of it all.” The twin pillars on the life sciences side are Andrew Wells and Claire Irvine. Chemistry head Wells holds a PhD in vaccinology and also worked in-house at a multinational pharmaceutical giant; while “fearless warrior” Irvine lately played a vital role in securing patents for the use of Synairgen’s Interferon-beta drug to combat the respiratory symptoms of covid-19. “Claire pays meticulous attention to detail and has superb technical and scientific knowledge. Clients can concentrate on their own growth, knowing their IP is in safe hands.” When it comes to transactions, 30-year-experienced solicitor Janet Knowles “combines strong technical ability with a friendly manner” and recently sewed up a patent-related deal between Extruded Pharmaceuticals and a leading university. Bridging the gap between the prosecution and transactional divisions is astrophysicist Matthew Cassie, who crafts technically complex filing strategies and advises on IP-related M&A. The whole operation is overseen by senior partner and former radiofrequency engineer Harry Hutchinson, whose broad remit encompasses everything from telecommunications to 3D printing. His commercial outlook and strategic mind separate him from the competition.

Hogan Lovells

High-stakes patent litigation is in Hogan Lovells’ DNA, as the UK team’s caseload bears out: over the past 12 months it has handled a series of validity actions on behalf of Merck Sharp & Dohme; intervened in a sprawling multi-jurisdictional suit on behalf of HTC against Philips; acted for Olaplex in infringement proceedings against L’Oréal; and taken on a pan-European FRAND licensing case on behalf of Vodafone. Leading on the HTC and Vodafone mandates is litigation head Paul Brown, who has unparalleled insight in the electronics and telecommunications field, especially where FRAND issues are concerned: “He is somewhat unusual among senior partners, in that he is still willing to get into the detail of a case and really understand what it is all about. That, combined with a great nose for the best arguments, makes him a terrific litigator.” Also playing a hand on the HTC and Vodafone briefs is “amiable and technically adept” solicitor-advocate Katie McConnell. She litigates with poise in both the telecommunications and pharmaceutical spaces, and also has an eye for commercialisation opportunities – she recently advised Novartis on its AI-related collaborations with Microsoft. The Olaplex piece is spearheaded by Stephen Bennett, who has taken a record-breaking number of SPC matters to the Court of Justice of the European Union (CJEU). “Stephen has been there and seen it all before. He is unflappable, down to earth and urbane – as cool as a cucumber, even when the pressure comes on. He is pragmatic, straight-talking and legally astute – one of the finest UK solicitors in the life sciences field.” Working alongside Bennett on the Merck Sharp & Dohme case are Daniel Brook and Emma Fulton. The former is a skilled coordinator of cross-border litigation who brought home the ground-breaking Schutz v Werit Supreme Court victory; while the latter represents major players in both the healthcare and electronics fields. Both attract rave reviews: “Daniel Brook is one of the brainiest solicitors in England. His legal acumen is flawless, his knowledge is unending and his ability to calm nervous witnesses is a panacea.” “Emma Fulton is precise, intelligent, lively, engaging and able to handle complex patent and SPC issues with ease. If you need a job done well, she’s your woman.” The firm recently added former Herbert Smith Freehills partner Joel Smith to its ranks; Smith is a litigator and deal negotiator par excellence, Smith is also a top specialist in plant variety rights and was called on by the UK government to advise on this area in relation to Brexit.

J A Kemp

“Outstandingly good tactically, strategically and operationally”, is the market consensus on dynamic patent attorney firm J A Kemp. From three UK offices and additional bases in Paris and Munich, it has turned filing into an art form: its already staggering patent application numbers recently saw a 9% increase, with European patent filings now standing at 1,745 across a 12-month period. It consistently gets the right results in oppositions too, and currently has circa 320 active cases on the go, including a series of actions for AbbVie. Handling these is pharmaceuticals head Ravi Srinivasan, who has also been managing the patent strategy of Sanofi in relation to its Plerixaflor cancer drug. “His insights and attention to detail are second to none; and he is efficient, organised and highly effective.” Biotechnology and life sciences group head Patrick Campbell has appeared in more than 70 oppositions before the EPO and regularly advises on cross-border litigation. He is joined by Simon Wright and Sarah Roques, each of whom has chalked up 30 years in the game. Wright has made loyal fans of everyone from small academic institutions to major multinationals such as Hoffman-La Roche; while his role as secretary of the epi Biotech Committee puts him front and centre of European policymaking. Biotechnology is the specialist subject of Roques, a regular advocate in antibody-related EPO oppositions and a vital ally for US clients seeking to navigate the European patent system. Medical devices maven Nigel Price also builds relationships across the pond, collaborating regularly with US patent attorney firms based in Silicon Valley and serving as the key contact point for the firm’s US and China-based IT clients. Captaining the medical devices practice group is Mark Roberts, a veteran of more than 100 oppositions and appeals. “Mark has one of the sharpest legal minds I’ve had the opportunity to work with,” reports one client. “He is an excellent communicator – he can unwind complex issues with an elegant simplicity. He is easy to work with and never misses a beat.” John Leeming knows everything there is to know about computer-implemented inventions; he focuses on semiconductor device manufacturing and AI issues, and “finds clients a path to success even in cases when other attorneys would advise giving up”.

Keltie LLP 

“Keltie is home to some of the best patent attorneys on the UK market. Their advice is thoughtful and strategic, and they can see around corners to save time and cost down the road while obtaining commercially valuable patents. The team is very amenable, proactive, friendly and well suited to modern ways of working.” Anchoring the life sciences side is molecular biologist Devanand Crease, who has carved a niche advising university spin-outs and start-ups: “Dev is proactive in developing a strategy that is creative and goal oriented, and is a great team player – consistently collaborative and overall solid and reliable.” PhD biochemist Michael Moore spent time working at a gene therapy start-up, where his cutting-edge research saw him named as an inventor on numerous patents. Jonathan Goodacre likewise holds a PhD, this time in organic chemistry; everything from CRISPR to oil and gas technologies falls within his broad wheelhouse. This technical diversity is shared by former UKIPO examiner Judith Caldwell, who is fluent in disciplines including pharmaceuticals, cosmetics, veterinary science and medical devices. She devises sophisticated patenting strategies and conducts hawkish IP due diligence. On the engineering side, the firm is armed with Joanne Hopley and Sullivan Fountain. Hopley can quickly parse almost any engineering invention thanks to her impeccable credentials and training (including a PhD in nuclear structure physics), and manages the worldwide patent portfolios of various global automotive companies. The interface of engineering and software is the sweet spot of mechatronics expert Fountain, who previously worked as an avionics systems engineer and also in-house at Dyson. Further software know-how comes from Shakeel Ahmad and Richard Lawrence. Ahmad leads the IT, telecommunications and electronics teams and has a diverse practice which includes growing specialisms in fintech and 4G. Lawrence works well with emerging technologies and makes his debut in the IAM Patent 1000 thanks to glowing reviews from clients: “Richard has excellent people skills, responds well to feedback and is adept at communicating with inventors no matter what their needs or requirements.”

Kilburn & Strode LLP

Home to 100-plus multi-talented patent attorneys, mighty prosecution shop Kilburn & Strode continues to expand, adding four partners in the last year and investing further in its young Dutch office. Superior technical ability and client care are hallmarks of its service: “It has an understanding of the commercial aims, a complete grasp of the relevant patent law and a creative flair for seeing where opportunities lie.” It has several new arrivals in the IAM Patent 1000 this year, in the form of Nick Shipp, Jennifer Harris and Elizabeth Crooks. Shipp recently assumed leadership of the firm’s large tech group and coordinates its activities across London, Amsterdam and San Francisco, while also counselling innovators of all stripes in fields from consumer goods to aeronautics. Harris and Crooks both sit within the chemistry group: Harris is hailed as “technically knowledgeable and astute, and able to quickly formulate strong strategies and arguments”; while Crooks – who recently acted in a range of oppositions for Honeywell – “knows her chemistry as well as the inventors she works alongside, and is diligent and responsive. Her work is methodical and strategic, always conducted with a keen eye towards the client’s commercial and business interests”. They join an existing group of star professionals which includes life sciences experts Nick Bassil, Nick Lee, Tom Leonard and Kristina Cornish. Cancer immunotherapy, stem cell technology and cloning feature prominently in the practice of biotechnology ace Bassil, who is never less than meticulous in conducting IP due diligence and obtaining SPCs. Lee’s recent highlights include representing Immunocore in a major multi-party opposition hearing. With a niche in antibody technology, Leonard is “at the top of his game in terms of both technical ability and client service, providing fantastic strategic advice for almost any project”. Cornish chairs the life sciences and chemistry group and likewise garners high acclaim: “She is professional, efficient and comes up with imaginative solutions in challenging scenarios.” On the software side, Alexander Korenberg builds futureproofed patent strategies in cutting-edge areas such as AI, virtual and augmented reality, and cloud services. All manner of engineering briefs land on the desks of Jim Miller and managing partner Richard Howson, although both are especially adept when it comes to automotive technologies. Miller’s CV includes stints on the metalworking shop floor of an automotive transmission component supplier and at BAE Systems; while Howson currently dedicates time to marking the European Qualifying Examination for new patent attorneys. No discussion of Kilburn & Strode would be complete without a mention of chairperson and “rock star” Gwilym Roberts, who has become “the most famous patent attorney in Europe” thanks to his popular podcast, Two IPs in a Pod.

Kirkland & Ellis LLP

When US-headquartered juggernaut Kirkland & Ellis recruited crack litigator Nicola Dagg to build out its London patent team in 2018, the move was a hot topic among the UK IP community. Almost three years on, the practice is positively humming as it continues to pick up some of the highest-profile disputes on the market. On the pharmaceutical side, Dagg recently did battle in the Supreme Court for Pfizer and represented Regeneron in a major infringement and validity dispute which is cited as one of the most important biotechnology cases of the last 20 years. Dagg is not the only rainmaker at the firm, however: her growing squad also includes the likes of Steven Baldwin and Katie Coltart. Baldwin’s cases tend to have a cross-border angle – as illustrated by the globe-spanning, precedent-setting FRAND dispute he has lately handled for Xiaomi. Coltart is likewise an adroit coordinator of multi-jurisdictional litigation whose recent highlights include acting for Meril Life Sciences in a pan-European heart valve dispute with Edwards Lifesciences. Working with her on this is Daniel Lim, whose frequently weaves together the threads of parallel proceedings across countries and continents in his pharmaceutically focused practice. Working across both pharmaceuticals – where he concentrates on advancements in small molecules and vaccines – and consumer goods is Jin Ooi, who can swiftly resolve even the most complex damages enquiries. He assisted Dagg on the Pfizer piece and, alongside Lim, directed patent infringement and revocation proceedings on behalf of British American Tobacco across 25 jurisdictions worldwide.

Lewis Silkin

Lewis Silkin threw its hat into the patent prosecution ring in 2019 by acquiring and integrating former patent attorney outfit Ablett & Stebbing into its offering. With this experienced, technically capable team undertaking everything from basic filings to complex freedom-to-operate and IP strategy, the firm now provides a 360-degree patent service. On the prosecution front, it has been busy processing international patent filings for power supply manufacturer TDK Lambda; assisting soft drinks company Britvic with patent strategy; and tending to the patent needs of automotive supplier Aptiv. Playing a part on all of these matters is agile portfolio manager and engineering and software expert Tom Gaunt, who is “quick to understand new concepts and communicates easily with inventors”. “He is one of the best-networked patent attorneys in the game and his presence ensures that, despite the small size of its team, Lewis Silkin punches well above its weight.” Working alongside him for Aptiv and TDK Lambda is physicist Graham Ablett, a founder of Ablett & Stebbing whose aptitude extends from mechanics to electronics, telecommunications and software. Chemist Paul Williams is similarly versatile: he ably dispatches both mechanics and life sciences instructions, and assisted on the Britvic portfolio as well as on a series of opposition and appeal proceedings for Belgian pharmaceutical giant Janssen Pharmaceutica. On the litigation side, the firm recently recruited Antony Craggs, who has moved his sector-diverse practice from D Young & Co. He is known for his creative management of disputes across Europe and the United States.

Linklaters LLP

The tungsten-sharp practitioners at Linklaters have been putting on a show both in court and at the deal table for their A-list clientele. On the disputes front, they have been representing GlaxoSmithKline in pan-European infringement proceedings; Sanofi and Regeneron in a high-profile global dispute; and Takeda in commercially consequential litigation. And on the transactional side, they advised Bayer AG on its acquisition of UK start-up KaNDy Therapeutics; counselled BP International through the IP-heavy sale of its global aromatics and acetyls petrochemicals business to INEOS; and assisted Novartis with its subsidiary Sandoz’s purchase of Aspen Japan. The ambidextrous Ian Karet acted on both the GlaxoSmithKline and Novartis briefs. During more than 30 years at the firm, he has made innumerable appearances in the High Court and was recently appointed as a part-time deputy High Court judge in England and Wales. Another nimble operator on both sides of the contentious/non-contentious divide, pharmaceutical ace Yohan Liyanage drew on his biotechnology PhD to provide crucial input on the Sanofi/Regeneron dispute. Pure-play transactional lawyer Nemone Franks gets right into the nitty-gritty of IP-related cross-border M&A, complex IP and IT separation projects and high-value commercial contracts, with fintech a growing forte.

Marks & Clerk

Marks & Clerk is perhaps one of the most successful attempts at a hybrid outfit in Europe: its prosecution division lights a path to patent protection for innovators in new and emerging technological areas; while its litigators go in all guns blazing for the likes of pharmaceutical giants Pfizer, F Hoffmann-La Roche and Genentech. On the life sciences side, notable patent attorneys include Sheila Wallace, Will Nieuwenhuys and Jonathan Stafford. Wallace casts her net wide, focusing on pharmaceuticals but covering everything from agrochemicals to polymers – she has made her fair share of appearances in EPO oppositions and is also a dab hand at obtaining SPCs at patent term extensions. Small molecules are the metier of Nieuwenhuys and Stafford. Niewenhuys “provides clear advice in complex situations, allowing clients to make confident, well-informed decisions”. Stafford – who holds an organic chemistry PhD and gained industry insight through a stint at a multinational pharmaceutical company – is “the quintessential full-service practitioner, with the perfect balance of acumen, command and reliability”: “He understands a wide variety of complex technologies and is astute at identifying the opposition’s weaknesses and turning them in the client’s favour.” Bridging the gap between the life sciences and high-technology spheres is Robert Lind, a bioelectronics PhD who also has deep telecommunications know-how: having worked with 3G and 4G technologies at Nokia, he now advises on issues that touch on 5G and other advanced wireless communication systems. “Robert always goes the extra mile to fully understand the technology and the client’s long-term business strategy.” Heading the electronics group is physicist Philip Martin, who has led more than 70 EPO oppositions across his career, with an enviable success rate of circa 90%. Sharing this strength is electronic engineer Philip Cupitt, a veritable encyclopaedia of US patent procedure thanks to his time at the London outpost of a major US law firm. The resident 3D printing and additive manufacturing expert is German, UK and European patent attorney Thomas Prock, who is frequently engaged to speak on his topic of choice at EPO conferences. Captaining the Marks & Clerk Law practice is Mike Gilbert– the aforementioned Pfizer, Genentech and F Hoffmann-La Roche cases all bear his fingerprints, and he has an intuitive grasp of SPC and paediatric extension issues. “Mike is a very experienced and excellent patent litigator who knows all the IP and regulatory law surrounding the pharmaceutical industry – it is almost impossible to imagine a situation that would be new to him.” Life sciences and high technology both fall within the bailiwick of Graham Burnett-Hall, who provides “excellent advice and recommendations for all types of UK patent litigation questions”. Also with a wide remit is Gregor Grant, a veteran litigator who has brought the heat for companies in fields from automotive engineering to pharmaceuticals and therapeutic antibodies during his 50-year career; he remains an illustrious figure at the firm today. For SEP and FRAND-related disputes, as well as the surrounding licensing issues, Dafydd Bevan is prime pick – he regularly appears in the High Court, he is adept at advising on the interplay between UK litigation and parallel EPO opposition proceedings. Michael Moore likewise has a facility for SEP and FRAND cases, though his sweeping technical know-how has seen him involved in multi-jurisdictional biotechnology battles too. He also heads the firm’s transactional IP practice and dispenses on-point guidance on freedom-to-operate issues. Fellow transactional and contractual expert Simon Portman counsels companies of every scale on all kinds of licence agreements and R&D collaborations, and brings a wealth of regulatory insight to the mix.

Mathys & Squire LLP 

“Mathys & Squire is dynamic and exceptional in its service. The team helps clients to adapt their strategies in line with business developments and proactively responds to changing external circumstances. Communication is clear and concise, even in relation to the most highly specialised and technical patent applications.” Much of its work takes place in a cross-border context, thanks to its extensive geographical footprint: a 10-office network across the United Kingdom and Europe is complemented by further outposts in China and Japan. Making their debuts in the IAM Patent 1000 for 2021 are electronics wizards Alan MacDougall and Paul D Cozens. Cambridge office head MacDougall takes the lead in managing the firm’s Japanese business development; while Cozens is an intelligent builder of patent portfolios with an affinity for the cutting-edge fields of AI and cryptocurrency. “Paul has a winning combination of technical ability and commerciality, and is a pleasure to work with. He has dealt with some challenging projects and maintains a positive attitude even when faced with admittedly difficult tasks.” Other IAM Patent 1000 newcomers are Dani Kramer and Andrew John White – the former a prolific patent filer and smooth broker of technology-based agreements who is responsible for growing the firm’s Israeli practice; the latter a physicist who mentors start-ups in the medtech, software, telecommunications and automotive fields. “Dani practically unfolds his knowledge in simple terms, providing highly targeted and tactical advice, and painting a clear strategic map.” “Andrew shows great technical understanding, ensures that the core IP is well defined at an early stage, facilitates joint creative thinking and is always available for a productive discussion.” The final fresh face in the rankings is biotechnology and life sciences ace Anna Gregson, who is especially at home working with university technology transfer organisations: she is currently conducting patent searches for the London School of Hygiene and Tropical Medicine in relation to small molecule therapeutics. Returning to the IAM Patent 1000 this year are Jane Clark, Martin MacLean, Craig Titmus and Christopher Hamer. Clark has been delighting high-technology concerns and universities alike for more than 30 years with the sage global strategy and lucrative IP-related agreements she masterminds.  MacLean exhibits a deft touch in managing the portfolios of both corporations and governmental organisations – especially in the biotechnology sphere – and has conducted more than 100 EPO opposition hearings, with a 90%-plus success rate. Titmus also excels in administrative proceedings and shares MacLean’s proficiency for working with players in the vaccine and therapeutic antibody fields; while chemistry boffin Hamer leads the firm’s efforts in China and is “a pragmatic and proactive professional who frames legal issues in a commercial context”. Recent successes include helping Acell Industries to patent its cutting-edge covid-19 related air filtration technology.

Mewburn Ellis LLP

A venerable presence on the market for over 150 years, leading European patent prosecution shop Mewburn Ellis refuses to stand still, as the stats bear out: it enjoyed an astonishing 40% growth in turnover over the last three years. Its 130-plus patent professionals cover all technical niches in chemistry, IT, engineering and the life sciences, and have partnered with eight of the top 10 UK universities. Leading on the life sciences side is the 30-years’ seasoned Simon Kiddle: “His work is of a notably high quality, his strategic advice is clear and effective, and his judgement is sound.” He leads a robust practice group which includes the likes of Seán Walton, Christopher Denison, Simon Kremer and Nick Sutcliffe. Antibody and vaccine expert Walton has spent the last three decades making the difference in EPO oppositions and appeals, and intervening in USPTO interference proceedings. Antibodies are likewise the metier of Denison, an agile manager of weighty biotechnology portfolios and a persuasive performer in oppositions: “Chris is second to none, by far, in finding necessary support documents and coming up with creative and truly science-based arguments. He never disappoints in producing robust briefs and beating multiple opponents at the oral proceedings.” Biochemist Kremer’s clients include innovative pharmaceutical company WisTa Laboratories, which he recently assisted in inter partes review proceedings before the US Patent Trial and Appeal Board. Sutcliffe also holds a biochemistry PhD and handles everything from pre-drafting advice to global portfolio management and advocacy in oppositions: “Nick is the agent to go to for an accurate, unbiased opinion. He has an impressive ability to digest written material and draft claims with pertinent questions for the inventors without the need for hours of meetings.” The engineering group plays host to Rachel Oxley, Simon Parry and Emma Graham, who all receive effusive praise from patrons. London engineering head Oxley “has an unprecedented ability to put complex inventions on paper and an exemplary approach which is logical and underscored by a high level of understanding”. The “personable and client-focused” Parry is an automotive and marine engineering specialist; while optics and photonics maven Graham is a valuable resource for start-ups who “provides high-quality advice and always goes the extra mile”. Stephen Gill has aeronautics, rail transport and power generation down cold; he has been furnishing holistic strategic guidance to Hitachi Ltd alongside “proactive and accurate” engineering and ICT practice group head Graeme Moore. Moore also linked up with chemistry group head Jeremy Webster to provide full-bodied IP support to Mitsubishi Electric Corporation and e-cigarette manufacturer Nerudia; Webster’s other recent credits include managing the portfolio of worldwide chemical industry group Toray Industries and handling a series of successful oppositions for Unilever. Working alongside him in the chemistry group is Robert Watson, who balances a wealth of prosecution and oppositions work in the pharmaceutical and industrial chemistry sectors with a thriving designs practice. Bolstering the firm’s offering having joined the team from Charles Russell Speechlys in February 2021 is David Fyfield – the multitalented litigator, strategist, and contract negotiator is used to dealing with multijurisdictional issues across Europe, the US, and China.

Mishcon de Reya LLP

Perhaps best known for its prowess on the trademark side, Mishcon de Reya is also home to a potent patent practice which has all disciplines on lock – although its track record for generic pharmaceutical companies is particularly impressive. This year it brought a hard-fought battle between Lupin and Gilead over HIV drug PrEP to successful close; the case went all the way to the Court of Appeal and then the CJEU, and the judgment that Mishcon secured will have a seismic impact on the generics industry. Playing point on this matter was patent practice head David Rose, an authority on everything from SPCs to FRAND licensing. “David is an extremely accomplished litigator with significant experience of high-value patent litigation. He brings a wealth of experience and maturity to any patent dispute, engenders the trust of his clients and is a pleasure to work with.” Another versatile IP litigator is Martyn Hann, who also advises on all manner of licensing, R&D and collaboration agreements. In the words of one happy client: “Martyn continues to be one of our most trusted legal advisers. He delivers clear, decisive advice, putting the legal concerns in commercial context and always ensuring that his guidance is of practical use.”

Osborne Clarke 

The IP group at Osborne Clarke received serious shots in the arm over the past 18 months – first with the arrival of new life sciences and healthcare head Will James in 2019, and then through the recruitment of former Bird & Bird pharmaceutical and biotechnology litigator Tim Harris in 2020. “Clear communicator and superb strategic leader” James has carried the day in court for the likes of Amgen, Genentech and AstraZeneca, and is “brilliant” at coordinating multi-jurisdictional patent litigation. Harris puts his Oxford chemistry qualifications to great use in assisting biotechnology players with their IP monetisation strategies; a facility for electronics inventions is another string to his bow. The pair join polished litigator Arty Rajendra, who concentrates on high technology and telecommunications; she made an indelible mark on the scene through her representation of Unwired Planet in its landmark Supreme Court FRAND licensing dispute against Huawei.

Penningtons Manches Cooper LLP

A flair for the fine print of IP-rich transactions lands Penningtons Manches Cooper its first spot in the IAM Patent 1000 this year. No patent-related agreement is beyond its capabilities – universities and their spin-outs are a clear focus, but biotechnology and industrial chemical concerns of all shapes and sizes have been seeking out its support over the past 12 months. Driving the practice forward is Chris Shelley, who negotiates lucrative deals involving engineering and life sciences technologies and shares his wisdom by teaching on the IP Transactions: Law and Practice Course at the UCL Institute of Brand & Innovation Law. “Chris provides clear and professional advice in a responsive and prompt manner.” At his side is fellow life sciences aficionado Rachel Bradley, who gained an insider’s perspective on IP transactions in her former role of corporate counsel at AstraZeneca. She “offers thorough and timely support and demonstrates strong market knowledge and experience”.

Pinsent Masons

“Thorough, organised, commercially sound and great at developing relationships with foreign counsel”, Pinsent Masons “acts as an extension of an in-house legal team”. The patent professionals across its European office network work hand in glove to meet and exceed the demands of its discerning clientele. Pharmaceuticals and biotechnology industries are happy hunting grounds, and generics leader Teva is a key client of note: cases which look set to make a splash include a Supreme Court spat with Eli Lilly/ICOS Corp; an SPC-related revocation dispute against Gilead and three other defendants in the CJEU; and a high-stakes damages claim against Warner-Lambert and Pfizer alongside a league of other claimants. Acting on all three is Charlotte Weekes, an internationally minded warrior with keen commercial acumen. IP and life sciences head Clare Tunstall – dubbed “the queen of the generic revocation case” – leads the charge against Gilead: “Her experience in the field is unparalleled and she is fantastic to work with.” Teva also receives vital support from Christopher Sharp, who has elsewhere prevailed for Accord Healthcare in revocation proceedings against Allergan Inc; he is “an excellent leader who is clear and decisive in his advice”. Another hotshot life sciences litigator is Nicole Jadeja, who gave the group a boost when she came on board in late 2019. She can walk in her clients’ shoes, having previously worked at a pharmaceutical multinational in a scientific capacity. On the transactional end, Allistair Booth has been getting a wide range of licensing and R&D agreements inked for the likes of RedX Pharma, 4D Pharma, and Evgen Pharma.

Potter Clarkson

The star of Potter Clarkson remains firmly on the ascendant, despite the travails that have beset the market in the pandemic age. Home to both patent attorneys and solicitors, the hybrid outfit tackles contentious and non-contentious mandates of all flavours with verve, though EPO oppositions are a particular forte. In 2020 it landed two big names in the form of Peter Finnie and Fiona Law, who have both since played crucial roles in establishing the firm’s newly minted IP consultancy division and recently assisted German medtech venture capital company Earlybird with IP due diligence. Telecommunications, software and AI expert Finnie builds commercially oriented patent strategies for European start-ups; while the “diligent, professional and perseverant” Law is a chemistry and pharmaceuticals specialist with an affinity for SPC and second medical use issues. Joining her in the life sciences division are patent attorneys Charlotte Crowhurst, Stephen McNeeney, Ian Dee, Richard Bassett, Rob Pugh and Stephanie Pilkington. Crowhurst is a percipient IP strategist and EPO advocate who has done much to advance the firm’s Asian business development, acting for corporate titans from China and Korea. Organic chemist McNeeney is a trusted guide to pharmaceutical clients based overseas, especially in Sweden, and also advises on US court proceedings. Dee has wrapped up more than 150 EPO hearings during his tenure and brings research experience at a chemical multinational to his broad practice; while Bassett has appeared in some 200-plus oppositions on behalf of major leaguers such as Baxter Healthcare, Eli Lilly and AstraZeneca. Pugh is “consistently responsive, paints a clear strategic picture for clients and quickly understands both the technical and business aims”; while PhD molecular biologist Pilkington is hailed as “amenable, scientifically astute, flexible, prompt and conscientious”. On the electronics side, Craig Brownlie and Saiful Khan recently advised Douglas Scientific on its worldwide patent strategy. Brownlie’s solid-state physics PhD informs his “reliable commercial advice” in the nanotechnology sector; while the “responsive, sharp and honest” Khan’s stint in-house at Nokia proves invaluable to his broad multinational electronics and computing practice. “Dedicated, strategic and commercially minded” textiles specialist Caroline Marshall can be found in the engineering and designs group – her knowledge base is as broad as it is wide, and she acts as a European IP adviser to renewable electricity group UK Grid Solutions. Contentious nous is supplied in abundance by Richard Roberts, Mark Snelgrove and Oliver Laing. With impeccable academic credentials in chemistry, Roberts shines in particular at the interface between civil and criminal IP enforcement. Snelgrove and Laing both have silky transactional skills: Snelgrove’s experience in disputes ensures means he always keeps the potential contentious angle in mind; while Laing has multi-jurisdictional collaboration and licensing agreements within the life sciences realm sewn up. He is also an engine of the firm’s thriving Scandinavian business and brings insight from a secondment at a world-leading health and beauty group. Guiding the firm’s activities in a consultancy role is Ray Charig, a talented physicist who draws on 25 years of experience working with successful start-ups to build multi-dimensional patent strategies that tick every box.

Powell Gilbert LLP 

The plaudits come thick and fast for patent litigation powerhouse Powell Gilbert: one client calls it “the top set of solicitors in the UK”, while another reports: “It is a well-regarded firm with excellent partners and excellent associates, all with scientific expertise.” No stranger to landmark lawsuits, it valiantly fought the corner of Huawei in its headline-grabbing battle with Unwired Planet – a case which came interlaced with hotly debated FRAND licensing implications. Leading on this were Simon Ayrton, Zoë Butler and Peter Damerell. Ayrton and Butler recently put their advanced FRAND know-how to further use in representing patent licensor Access Advance in the first UK FRAND suit without an associated patent infringement claim. “Simon and Zoe are creative thinkers with a strong understanding of a complicated and fluid area of law. The combination of their business mindset, legal fundamentals and creative thinking results in high-quality, focused counsel.” Like Damerell, Butler also moves the needle for life sciences players: she has been acting for Biogen for the last five years, while cellular physiology PhD Damerell regularly features in high-value SPC disputes. Similarly dividing his time and attention between FRAND/SEP battles and complex healthcare device disputes is Tom Oliver, whose academic background in biochemistry proves invaluable on the latter side of his practice. He has lately gone out to bat for Actavis in a high-value damages claim against Pfizer, alongside colleague Bethan Hopewell. “Extremely bright and a big-picture thinker, Bethan is sharp on the science as well as the law and stays on top of all the detail. She is exceptional in every aspect – experience, strategy, execution and responsiveness.” Also active in the life sciences are Timothy Powell and Siddharth Kusumakar. Powell recently teamed up with Hopewell on a commercially significant second medical use and vaccine-related matter for GlaxoSmithKline; and with Kusumakar in multi-jurisdictional proceedings on behalf of Edwards Lifesciences. “Tim has a huge amount of experience and just ‘gets it’. He is a calm and knowledgeable presence who can immediately get to the nub of any tricky issue.” Academically qualified in microbiology and immunology, Kusumakar “thinks strategically and knows the important points to push and those to keep in reserve”. “He is unflappable, dependable and gives sound legal advice that helps to advance our business needs.” He recently defended Kymab in a major Supreme Court dispute against Regeneron alongside founding partner and solicitor-advocate Penny Gilbert, whose practice – which regularly sees her visit the Supreme Court and the CJEU – is informed by a doctorate in molecular biology. Chemist Tim Whitfield combines his patent work with a focus on pharmaceutical regulatory and SPC issues. “Incredibly calm and collected under pressure, he never loses sight of clients’ commercial objectives. Tim looks 10 steps ahead and manages large teams effectively while keeping on top of the details and regularly making insightful observations.” For electronics, IT and telecommunications matters, strategist and FRAND licensing ace Ari Laakkonen is “simply brilliant at developing winning strategies, and thorough and detail oriented when preparing a case for trial”. His fellow global strategist is Alex Wilson; fluency in French and German, a spell spent practising in Australia and experience as a former examiner at the EPO all give him a uniquely cosmopolitan perspective.

Reddie & Grose LLP

The formidable team at Reddie & Grose partners closely with patrons to obtain cast-iron patent protection in the most business-focused, cost-effective way. Its diverse clientele includes everything from AI and high-technology start-ups to biotechnology multinationals, US financial services players and Chinese giants such as air conditioning leader Gree Electrical Appliances. “The granting rate is very good with Reddie & Grose – it is crafty in the way it formulates patents, providing plenty of fallback positions during the examination process.” Michael Roberts and Neil Thornton anchor the life sciences division. Roberts holds a PhD in molecular genetics and conducted postdoctoral research in plant molecular biology and genomics, all of which feeds into his diverse practice; while biochemistry PhD Thornton speaks the language of SMEs. On the engineering front, the key names are William Ponder and Paul Loustalan. Physicist Ponder is a deft coordinator of global patent filings and a worthy EPO advocate whose broad remit encompasses medical devices, e-cigarettes, wireless network technology and aerospace technology; while mechanical engineer Loustalan is a favourite among automotive companies and holds an engine-related PhD. Innovations in the electronics and computer-implemented inventions are parsed with ease by fluent Japanese speaker Nick Reeve, who has spent time living in the Nagasaki Prefecture and lectures on Japanese Patent law at Queen Mary University.

Reed Smith LLP

As one of only a handful of commercial law firms with a vibrant IP practice on both sides of the Atlantic, Reed Smith is ideally positioned to provide a joined-up global service to its prestigious multinational clientele. Its specialists worldwide consider themselves part of a single team and work hand in glove across borders to secure the right results, wherever and however they may be needed. New client wins on the contentious front include petroleum storage tank manufacturer Dover Corporation and pharmaceutical company BSPG Laboratories, both of which are represented by London patent practice head Jonathan Radcliffe. Radcliffe is a seasoned litigator of some 30 years’ standing and an eminent figure on the market: he was recently engaged to advise the Kazakhstan administration on the reform and redrafting of its entire IP regime. When not in court, he guides industry leaders through the negotiation and closing of lucrative IP-related deals, such as Microsoft’s recent acquisition of Metaswitch Networks. Assisting him on the latter was savvy transactional lawyer Philip Thomas, who combines IP and data protection expertise with in-house insight from stints at Nortel Networks and Virgin Media predecessor ntl.

Schlich Ltd

Based in Littlehampton, West Sussex, patent attorney outfit Schlich Ltd is a preferred choice for both UK and Chinese clients in need of efficient filing, adept portfolio management and staunch defence of their rights before the EPO. It operates at the cutting edge of biotechnology, chemistry and mechanics, and has lately been handling a significant volume of CRISPR-related actions. In the hotseat is namesake George Schlich, whose academic background in natural sciences translates into deep technical understanding: “He is extremely skilled at opposition procedure and practice, and always keeps clients informed on developments in clear language.” This collaborative approach is shared by biochemistry PhD Juliette Boynton, who manages international portfolios with a sure hand and provides unerringly pragmatic advice: “Her strategies are clear and robust; she can get up to speed on complex technologies quickly; and she navigates challenging examinations with finesse.”

Secerna LLP 

“The expertise at Secerna is very high and the quality of the drafting is first rate,” report commentators of this York-based prosecution shop. “Its strength is its ability to take ideas from inventors, quickly grasp and understand the concept, and turn it into a patent application with cleverly structured language.” The group is led by co-founders Jason Boakes and Charlotte Watkins. Engineering, telecommunications and medical devices are fortes for Boakes, a “very astute and knowledgeable patent practitioner who takes great care to ensure the work he produces is well thought through and accurate, and who explains concepts easily and clearly”. “He is very sensitive to cost pressure and works efficiently to maximise value for his clients.” With a focus on the life sciences, Watkins “goes above and beyond the call of duty for her clients, doing more for them than many other European practitioners. She becomes an essential part of their patent teams, puts in the effort to make herself indispensable, grasps the science easily, and is extremely knowledgeable about European practice and case law”.

Simmons & Simmons LLP

Having made the leap in 2018 to add prosecution capabilities to its offering, Simmons & Simmons is now one of those rare breeds in the UK that provide a wall-to-wall patent service. Electronics specialist Kevin Cordina heads the pan-European prosecution unit, which tends to the needs of A-list innovators such as Apple, 5G network pioneer TCL and medical devices leader 3M Wound Care. Cordina himself “is not only a procedural expert, but also takes the time to understand both the technology and business concerns”. Filings in the life sciences are ably dispatched by Frederick Nicolle, who acted on behalf of Serenity Pharmaceuticals and Natura Cosmeticos before the EPO this year; patrons appreciate his “highly valuable strategic advice, accurate approach and cooperative spirit”. The firm remains a go-to for high-stakes litigation and continues to play a role in some of the most prominent biotechnology cases going: it recently represented new client UCB in High Court patent revocation proceedings against Genentech and Novartis; Gilead in a major SPC-related suit; and Samsung Bioepsis in multi-jurisdictional biosimilar patent litigation. Taking the lead on all three pieces is Scott Parker, who draws judiciously on his technical background in biochemistry and molecular biology to defend the interests of pharmaceutical innovators to the hilt. Alongside him are Kevin Mooney and Andrew Hutchinson – Mooney is an elder statesman of the IP world who regularly helps to shape policy and legislation, and advises the EPO on judicial training; while Hutchinson recently fought the corner of Bayer HealthCare in patent revocation proceedings brought by Teva. Priya Nagpal and Michael Burdon likewise relish the rough-and-tumble of sector-diverse, multi-jurisdictional disputes. No technology is off limits for versatile chemist Nagpal, although she has carved a growing niche in cutting-edge areas such as AI, blockchain and fintech; while Burdon is a gladiator in SEP and FRAND battles who recently provided game-changing representation to high-technology company AIXTRON in an ownership dispute. Meanwhile, Angus McLean, Michael Gavey and Lydia Torne excel at getting signatures on the dotted line of IP-rich deals. McLean is a smooth negotiator of transactions in the fintech field for the likes of blockchain consortium Contour, which counts HSBC, NatWest and Bangkok Bank among its members. Heading up the London IP group, Gavey “applies his vast legal knowledge and thoroughly analyses all facets of a case to secure the best outcomes”. Impeccable contractual drafting is the calling card of Torne: “She has an in-depth understanding of the biotechnology industry and is a true expert in the field of patent law.”

Slingsby Partners LLP

Founded in 2013, patent prosecution outfit Slingsby Partners is on a stellar upwards trajectory, with headcount growing fivefold in the last eight years and year-on-year turnover rising by an average of 30% for the last six. It has its gaze squarely trained on faraway horizons, and China and Japan are becoming increasingly significant markets for the firm. Engineering, electronics and physical sciences are strongholds, as reflected in its client roster: for example, it manages the portfolio of chip designer Imagination Technologies and directs global patent strategy for surgical robot manufacturer CMR Surgical. Founder and software maven Philip Slingsby marries a fine-grained appreciation of US patent law with insider insight from his time at Nokia. At his side is David King, who also advises on US procedure and recently counselled Sirus Minerals on the IP elements of the $2.9 billion mining facility it is developing in Yorkshire. Also on board are poised EPO advocates Paul Roberts and Stephen Turner, who both move in the high-technology field. Roberts has a burgeoning machine learning practice and stands out for his “enthusiasm, sharpness of mind and exemplary communication skills”; while Turner regularly lectures in Japan on European IP regimes and “has an invaluable ability to grasp technical concepts and get to the core value of an invention quickly”.

Stephenson Harwood LLP

Household-name multinationals – particularly in the life sciences – flock to the doors of Stephenson Harwood. It has its boots on the ground in almost every continent and by coordinating with its sister offices and collaborating with its high-profile clients, the team finds pragmatic solutions to complex multi-jurisdictional skirmishes. For example, one of its most recent and notable highlights includes its recent implementation of a worldwide litigation programme for GlaxoSmithKline against Sandoz and Glenmark Pharmaceuticals. Its IP transactions practice is especially potent – not least thanks to the efforts of chemist Alexandra Pygall, who is also a polished litigator. She “never fails to deliver extremely high-quality work product and is utterly brilliant with clients, navigating the sometimes difficult line of providing practical, no-nonsense advice while addressing business-sensitive topics”. Pygall has lately been assisting Oxford Biomedica with a range of IP-related contracts, licensing agreements and other arrangements in relation to the AstraZeneca covid-19 vaccine, for which her client is a key manufacturing partner. Working alongside her on this is fellow life sciences expert Naomi Leach, who consistently gets transformative collaboration and patent licensing agreements, as well as IP-related M&A deals, across the line. Litigation and transactions are the twin focuses of Rob Jacob, “one of the most effective IP lawyers out there”; he recently acted for Eureka Shipping in a High Court dispute which led to changes in licensing laws around the sale of damaged products. Guiding the whole operation is chief executive Eifion Morris, who built the IP group from the ground up and now steers the global strategy of the firm’s entire corporate offering.

Taylor Wessing

A “top-quality European IP firm” that adeptly navigates the vicissitudes of multi-jurisdictional disputes, Taylor Wessing has been hitting the headlines in the UK patent litigation space of late. Highlights include defending ASUS in a FRAND and SEP-related dispute against Philips; representing medical device leader Abbott in commercially significant patent infringement and preliminary injunction proceedings; and intervening on behalf of Ericsson in the ground-breaking Unwired Planet v Huawei suit. Taking the lead for ASUS are James Marshall and Christopher Thornham. Marshall has a complete command of both telecommunications and pharmaceuticals, and is dubbed a “master of his field” by peers. With an academic background in experimental physics, Thornham has spent time advising on patent law in the United States and has “an unpretentious, down-to-earth attitude and the ability to easily discuss complicated legal and technical arguments”. Abbott is under the care of medical devices sage Nigel Stoate – a deft coordinator of sprawling disputes across Europe, the United States and Asia – and international patent group and UK life sciences groups head Simon Cohen, who comes armed with biochemistry and genetics expertise and a wealth of pharmaceutical regulatory know-how. Also with pharmaceutical knowledge is molecular immunology PhD Matthew Royle, who recently prevailed for Mylan in preliminary injunction proceedings brought by its generic competitors. With niche insight in areas such as SPCs and paediatric extensions, he is a valuable adviser to all life sciences players. Meanwhile, transactions in the life sciences are routinely brought to successful close by Colin McCall, who “shows fantastic attention to detail and skill in working through sticking points in a contract discussion. He is diligent, insightful, attentive and very pleasant to work with”.

UDL Intellectual Property

Storied patent attorney outfit UDL has a 125-year history and is recognised for its enduring client relationships, technical dexterity and 360-degree counsel interlaced with rich legal, scientific and commercial threads. At the fore on the life sciences side is PhD and postdoc-qualified Simon Mitchell, who has been busy managing the international patent portfolio of Benchmark Holdings and challenging third party patents at inter partes opposition and appeal proceedings. Software and telecommunications are fortes for the “pragmatic, commercially oriented and dependable” Karen Fraser, who is increasingly making forays into cutting-edge fields such as AI, Internet of Things and blockchain; dual qualification as an Indian patent agent and UK chartered patent attorney is a further distinction. “There is never a case left in free-fall with Karen; instead, it is as if every case has its own parachute and team of paratroopers in tow. She has a knack for fleshing out the minutiae of novelty from seemingly impenetrable technical specs and producing claims that are technically accurate, but still commercially useful.” Former UKIPO examiner and qualified US patent agent Andrew Alton is a software and electronics expert whose heavyweight clients have included both Microsoft and Apple.

Venner Shipley LLP

With both patent attorneys and solicitors stationed in four offices across the country and a fifth in Munich, Venner Shipley is a persuasive one-stop shop for innovators of all sizes from all corners of the globe. It knows all the right plays in administrative proceedings and currently has 458 ongoing oppositions and appeals in train; it has also become an elite player in the AI space, processing more patent applications in the field than any other European firm. The group has been filing for the Samsung Group for the best part of 40 years; today, this account is entrusted to the capable hands of managing partner and electronics and software head Jan Walaski. A dual-qualified patent attorney and solicitor, he works across a broad base of technologies and increasingly appears in contentious proceedings both before the EPO and in the UK courts. Another key client is British American Tobacco, which the firm has represented since 2007; Siân Gill plays a key role in directing its global patent programme. She heads up the chemical and life sciences team and also puts in resonant performances in oppositions and appeals. Building the portfolio of pharmaceutical start-up Inflazome – and guiding the company through its acquisition by Roche – are Allie Elend and Stephen Johnson, who both hold doctorates in organic chemistry from the University of Oxford and receive glowing feedback: “Allie and Stephen are incredibly knowledgeable, diligent, dedicated and also personable and fun to work with.” Another notable life sciences client is Sanofi, which has engaged software don Paul Derry and mechanical engineer Alex Brown to handle a huge volume of patent applications in relation to injector pen technology. Derry brings insight both from time spent in-house at an electronics and defence company and as a former UKIPO examiner; while Brown’s broad technical acumen covers everything from automotive and aerospace technology to manufacturing and industrial machinery. Also with electronics and engineering know-how are PhD physicists Richard Kennedy – who has a solid understanding of AI and deep learning-based technology – and Pawel Piotrowicz, who “provides thoughtful, practical advice for good value”. He recently represented Douglas Connor (now Bentley Systems) in the first EPO appeal to be livestreamed to the general public. EPO oppositions are likewise the metier of Tim Russell, who stands out for his “wide technical experience and strategic business advice”, and often assists on parallel administrative proceedings across continents. Anchoring the litigation side is barrister James Tumbridge, who “can get up to speed on any patent matter, has a solid knowledge of UK and European patent law, and is skilled at settling cases in a cost-effective way”.

Wiggin LLP 

Media, technology and IP boutique Wiggin may be best known for its copyright and trademark expertise, but it also packs a punch on the patent side, particularly when it comes to engineering and electronics innovations. The practice received a boost in July 2020 with the arrival of former Barclays global IP head and fintech oracle Calum Smyth, who has abundant software and high-technology know-how, having counselled Barclays through its digital transformation in recent years. “Calum has unrivalled breadth of knowledge in law and client management, shows technical flair and can embrace new and complex technical areas. He is a truly original thinker with great commercial acumen.” He joins IP head Sara Ashby, another all-rounder who makes light work of briefs where patents intersect with other IP rights and fraught contractual disputes. “She has a razor-sharp legal brain, but is still very commercial and client focused, and determined to get the best results for her clients. This all equates to a great success record.” Matters across the IP spectrum and extending into competition law are effortlessly dispatched by Michael Browne, who can quickly tease out the knots in cross-border disputes and joint development and licensing negotiations. He recently represented construction companies Permavent and Greenhill Industrial Holdings in a patent entitlement battle.

Wilmer Cutler Pickering Hale and Dorr LLP

Since consummate litigator Justin Watts came on board in 2017, the London outpost of this US-headquartered firm has been running hot on the radar: major high-technology, consumer goods and life sciences multinationals are increasingly seeking it out when must-win litigation looms. Watts enjoys a burnished reputation on the market thanks to his achievements over the years for the likes of HP, Sony Computer Entertainment and Johnson & Johnson. Alongside him is chemist Matthew Shade, a redoubtable ally in complex cross-border proceedings in fields as diverse as consumer electronics, medical devices and oil and gas. Another Swiss Army knife of a practitioner, though with a focus on pharmaceutical disputes, is solicitor-advocate Anthony Trenton, who has fought the corner of his clients in the country’s highest courts.

Withers & Rogers LLP 

Premier prosecution outfit Withers & Rogers arrives in the IAM Patent 1000 this year as “a standout firm that deserves recognition – it is highly capable and respected”. With a base in Munich and numerous multilingual attorneys on deck, it can offer a truly pan-European service; and its business-minded practitioners never fall down technical rabbit holes, but keep client strategy and commercial objectives front and centre on all instructions. Senior attorney and former Chair Karl Barnfather has done much to foster this creative, rewarding approach; he also shares his wisdom through frequent speaking engagements at conferences, including in his capacity as chair of the Licensing Executives Society IP Strategy Committee.

Other recommended experts

Based at Mohun Aldridge Sykes, meticulous patent attorney Christopher Aldridge is “reliable, friendly and feels like an extension of an in-house patent team”. “He leaves no stone unturned in his research and his extensive knowledge of the worldwide patent industry ensures clients can confidently sell their products around the globe.” Armed with a PhD in microbiology, Goodwin Procter’s Malcolm Bates has a flair for the fine print of life sciences transactions. Precision prosecutor and SPC expert Paul Brady of Abel & Imray is a biotechnology and pharmaceutical maven whose fluency in German proves immensely helpful to his European practice. Colleague James Ford – formerly a research scientist at QinentiQ – specialises in the automotive and aerospace fields, and excels at coordinating matters across Asia-Pacific and the Middle East. Clients in fields as varied as pharmaceuticals and agricultural machinery feel safe in the hands of Shakespeare Martineau’s resident IP all-rounder Nicholas Briggs, thanks to his ability to “get to the heart of the matter quickly in a straightforward, no-nonsense fashion”. “He is a high-performing and thoroughly competent professional, who is right at the top of his game. His thoroughness and keen eye for detail will never leave you feeling unprepared. Above all though, he is a fantastic and natural communicator, able to easily explain quite complex and subtle points of law in a readily digestible manner.” Former JA Kemp litigator Tom Carver has found a new home at Gunnercooke – he “provides practical, client-tailored, astute advice in all circumstances, and coordinates efficiently across overseas territories”, with China a particular specialty. Simon Chalkley draws on almost three decades’ experience in his innovative IP transactional practice, which he recently took to Keystone Law; franchising and technology transfer agreements and IP contract disputes of every flavour fall within his remit. Also at Keystone Law, English and Scottish-qualified Fiona Nicolson has similarly chalked up some 30 years in the game; she is an adroit negotiator of international licensing transactions for players ranging from start-ups to multinationals. The technically versatile Neil Coulson heads the global patent practice at Baker Botts; he provides incisive counsel on both IP strategy and cross-border licensing and transactions, and additionally brings advertising and sponsorship know-how to the mix. Clyde & Co’s Ralph Cox is a fan favourite among pharmaceutical generics, though no technology is off limits: his recent credits include acting for Oxford Nanoimaging Ltd in an inventorship and ownership dispute. Duncan Curley – the founder of IP litigation boutique Innovate Legal – combines legal nous with keen technical acumen, thanks to his PhD in medicinal chemistry. At Haley Guiliano, naval engineering expert Peter Hale is an all-rounder who is equally adept at portfolio management as he is in litigation and licensing scenarios. Former Mathys & Squire strategist Ilya Kazi recently established his own practice, IK-IP, in a move that made waves in the industry at large. He offers commercially tailored, cost-effective advice to innovators of all stripes. Mike Knapper heads Norton Rose Fulbright’s IP department and assists on all aspects of patent-rich commercial arrangements, including portfolio structuring, licensing and collaboration agreements, and M&A deals. At Brown Rudnick, Mark Lubbock provides future-focused IP and data privacy counsel across the contentious/non-contentious divide in wide range of sectors, with biotechnology a forte. Ashurst’s David Wilkinson is a formidable advocate for clients in disputes before the English courts and an astute representative in deal negotiations. Litigation and transactions are likewise the metiers of his colleague Don McCombie, who has an intuitive grasp of inventions in the oil and gas, software, life sciences and consumer goods spheres. Jones Day’s Alastair McCulloch loves diving deep into technically complex, multi-jurisdictional patent litigation; IP-related arbitration and trade secrets know-how are further strings to his bow. McCarthy Denning’s resident IP transactions ace is Jennifer Pierce: she “provides incisive and concise advice, can rapidly identify the crux of an issue and explains complex legal issues in an understandable and easily digestible way”. Anchoring Baker McKenzie’s international IP practice in the United Kingdom, Hiroshi Sheraton is a skilled coordinator of cross-border patent litigation whose biochemistry and molecular biology credentials grant him added technical insight. US-headquartered Finnegan’s patent star across the Atlantic is Anthony Tridico: his instant recall of both European and US case law and PhD in physical chemistry give him the tools to deal with the most technically and legally challenging patent briefs. AA Thornton’s Craig Turner has a PhD in neurophysiology and turns out precision patent applications for heavyweights in the oil and gas, biotechnology and pharmaceutical sectors.
