The rollercoaster that is the Unified Patent Court (UPC) has practitioners in the Netherlands on the edge of their seats. While significant legal challenges remain, the country is an important jurisdiction for patent litigation and the introduction of the UPC would likely result in amendments to current disputes being heard across all participating countries. That said, practitioners have been busy with an increase in disputes coming in from the telecommunications sector as global giants place more of an importance on key European countries. In the life sciences, new risks have come to light as IP owners are now liable to be sued by third parties if they assert rights that are subsequently invalidated according to a recent ruling by the District Court of The Hague. Moving away from litigation, R&D activity is healthy, investments and government expenditure remain steady and the Netherlands has once again been ranked favourably by WIPO in its global innovation index.

Firms: prosecution

Allen & Overy LLP

Allen & Overy’s Dutch outpost plays a vital role in the firm’s larger network, providing well-informed commercial strategies to its international clientele and assisting them with critical pan-European disputes. It has the legal and technical chops to prevail in must-win litigation across a range of sectors: thanks to its facility for SEP and FRAND-related issues, for example, it was recently called on to represent Dutch telecommunications company KPN in an infringement and licensing matter relating to the same. Running point on this is department head Frits Gerritzen, an “esteemed and truly terrific lawyer” who is also “an industry leader in the world of high-tech”: “Frits is attuned to developments in other jurisdictions and their impact on local advocacy. He is a brilliant, thoughtful and calming presence.”

AOMB Intellectual Property

Going from strength to strength each year, AOMB is a preferred choice for life sciences concerns. Based in four offices across the Netherlands and Poland, its practitioners marry rich academic backgrounds with keen technical savvy. Biotechnology superstar René Raggers’ incisive advice is backed by a PhD in research medicine and insight from several years as a senior scientist in industry. He is always willing to dive into the nitty-gritty, which is why patent procurement comes so easily him; while regular involvement in litigation proceedings gives him an edge when devising strategies. Joining Raggers in the guide this year is the “fair and open” Rutger Valkonet: “He always finds a healthy balance between a company’s profits and risks; and his understanding of cultural and historical differences makes him a valuable adviser to foreign clients too.”

Arnold & Siedsma 

Through seamless collaboration between bases in the Netherlands, Belgium, Germany and Switzerland, boutique Arnold & Siedsma provides a joined-up patent service to its illustrious clientele. For example, it is the only firm to assist Samsung across five of its business units, filing 300 European patent applications a year on behalf of the chaebol. Managing partners Joost Grootscholten and Petri van Someren run a tight ship. “Truly outstanding attorney” Grootscholten takes a measured approach and analyses a situation from all angles to come up with win-wins solutions for all parties. He specialises in software-related inventions; while van Someren has carved out a niche in the burgeoning plant breeding sector and works hand in glove with contacts around the world to secure clients cast-iron protection wherever it is needed. Alongside her in the biotechnology space is the efficient and pragmatic Marcel van Kooij, another crucial resource for start-ups and multinationals alike. The electrical, mechanical and computer engineering fields are further strongholds, thanks to the efforts of Paul Hylarides, Arjen Hooiveld and IAM Patent 1000 newcomer Bart Jacobs. “Paul’s advice is clear and honest, and provides true guidance.” A go-to for electronics briefs, he recently assisted Technical University Delft and The Boeing Company with their applications, and Fuji Seal International with patent strategy. Major league players from Japan seeking to safeguard their inventions in Europe have Hooiveld’s number on speed dial; while Jacobs has been busy managing Ampleon Netherlads’ portfolio and drafting patents for Teledyne Dalsa. “Bart is incredibly sharp, grasps complex technical concepts quickly and always does a great job. He is a pleasure to work with.” Medical technology matters are deftly handled by Rogier Brouwer and Martin Luten. Brouwer is a material science ace whose R&D know-how is underpinned by former in-house experience; while Luten “has a flexible approach and rapidly adapts to and understands foreign legal systems”. On the contentious front, Michiel Rijsdijk knocks it out of the park. An adroit coordinator of cross-border disputes, he maintains a vibrant trademark and patent practice which guarantees a holistic approach to multi-faceted proceedings.


Since its inception, BarentsKrans has provided game-changing support in complex disputes for global pioneers in the life sciences and telecommunications industries. For example, it has been working with Mylan for over 25 years on SPC and invalidation proceedings, while also advising on product launches and contractual matters. Playing an integral role on these briefs are Jaap Bremer and Marleen van den Horst. “They collaborate with external patent attorneys and in-house teams really well, and give everyone sufficient room to contribute and come up with valuable solutions.” Department head Bremer’s personable approach, eye for detail and deep patent knowledge are appreciated by those seeking to defend intricate inventions. Van den Horst has a similar penchant for advanced technologies and complicated cases, particularly in the life sciences. “In addition to the expertise she brings, I am also very impressed by the quality of Marleen’s efforts and her motivation to continuously support us in realising our dream,” reports one client. “We fought our case in multiple jurisdictions and Marleen’s defence was tried, tested and true.”

Biopatents IP Consultancy

Joining the Dutch rankings in the IAM Patent 1000 this year is Delft-based outfit Biopatents IP Consultancy. Located a stone’s throw from Delft University of Technology, and between the innovation hotspots of Rotterdam and The Hague, it is ideally situated to cater to the needs of both established high-tech companies and fledgling start-ups. Although the firm is relatively young, having set up shop in 2018, its founder and leading light Tom Wittop Koning supplies experience and insight in abundance. He is a seasoned European and Dutch patent attorney who manages patent portfolios, represents clients in critical patent infringement cases and coordinates cross-border litigation with equal finesse.

Bird & Bird LLP

Bird & Bird’s lofty profile on the European patent scene is likewise maintained by its Dutch contingent: the team “is brilliant at what it does” and combines “technical excellence” with “great commercial sense”. Fraught disputes in the high-tech and telecommunications industries are meat and drink to the firm: in recent highlights, “impressive litigator” Armand Killan has been battling it out for Qualcomm in international proceedings against Apple, as well as tackling SEP matters for Nokia. “He has great authority and brings great legal and technical knowledge to every case.” The life sciences practice has also been humming since the European Medicines Agency’s post-Brexit relocation to Amsterdam, with Bird & Bird quickly increasing its market share as a result. The firm is currently assisting leading biopharmaceutical company Ablynx in infringement proceedings under the watchful eye of IP division lead Wouter Pors. The tenacious advocate coordinates international litigation with a sure touch, as further borne out by his fine work for Bicycle Therapeutics in litigation which is being heard in Germany and the United States. Life sciences group head Marc van Wijngaarden and new hire Tjibbe Douma add further contentious firepower. Highly sought after for his agile handling of pan-European disputes and meticulous case preparation, Van Wijngaarden is in hot demand in other sectors too: he has been representing three entities from the Neo Materials Group and acted for Anheuser-Busch InBev in a global dispute against Heineken. Former Dentons lawyer Douma has “astonishing knowledge of foreign legislation and a great technical understanding that results in solid legal arguments. He is dedicated and has a can-do attitude that makes him a pleasure to work with”.


“Top IP firm” is tipped as “one of the strongest players in the Netherlands” thanks to the polished performances of its “fantastic litigators”. “When it comes to legal and technical content, they are real experts. They are quick on their feet, street-smart and have a no-nonsense approach.” A familiar face before the Supreme Court, biotechnology specialist Daan de Lange is “a brilliant patent lawyer with a talent for winning practically impossible cases”. The firm’s capabilities in the chemistry and pharmaceutical arenas are bolstered by Koen Bijvank and Mark van Gardingen. The technical background of “great advocate” Bijvank is “an asset to the team”; while van Gardingen is hailed as “intelligent, tenacious and the best patent lawyer in the Netherlands. He has the strategic foresight, advocacy skills and flair you need to get the ear of the court”. Rounding off the troop is Richard Ebbink, “one of Europe’s leading professionals” and a go-to for opposition work before the EPO.

De Brauw Blackstone Westbroek

A potent presence on the Dutch market, De Brauw Blackstone Westbroek adopts a hands-on, pragmatic approach to hammer out optimal outcomes in contentious and transactional settings. Its local practitioners join forces with colleagues in Belgium, Germany, the United Kingdom, China and Singapore to provide internationally scoped assistance on the large-scale matters that are their bread and butter. The rainmaker in Amsterdam is the “attentive” Gertjan Kuipers, a “strong and dedicated litigator who gets right into the details of every case”.

De Vries & Metman 

De Vries & Metman sets the bar for prosecution work in the Netherlands as a passionate and forward-thinking partner to cutting-edge innovators, whatever their discipline. The team showcases incredible versatility in securing total protection for the inventions of start-ups, SMEs and multinationals across the technical spectrum. Armed with a doctorate in applied physics, Louw Feenstra tackles tricky mechanical engineering matters with verve. He shares this specialism with Arnt Aalbers, whose vast industry knowledge proves a boon for medical technology, civil engineering and energy concerns. Holding the fort on the high-technology side is nanotechnology PhD Erik Visscher; he has an affinity for AI inventions and was formerly a researcher at the EPO. For contentious support in the electronics space, look no further than Ferry van Looijengoed, a patent attorney whose “contributions to litigation are extremely valuable”. In the life sciences, Lilian Hesselink capitalises on over 25 years in the game to generate IP value for her clients.


Full-service giant Dentons maintains a presence in 78 countries, has a phalanx of 10,000 lawyers on deck and is recognised worldwide for its superior contentious capabilities. The Dutch contingent is a central cog in this mighty international machine and frequently moves the needle for those embroiled in complex disputes. For example, the 14-strong unit recently assisted disruptive toy company Zuru in multi-jurisdictional proceedings; the firm acts for this dynamic player in 11 countries. In Amsterdam, Alexander Odle is the key contact for prospective clients.

DLA Piper

DLA Piper’s formidable Dutch strike force has captured the attention of numerous industry titans, as its current caseload attests. It recently scored a favourable outcome for Fresenius Kabi in a spat with Eli Lilly; and it continues to support leading companies such as Euro-Caps, the world’s second-largest producer of coffee capsules, in opposition proceedings. The marquee name is Paul Reeskamp “a top-quality lawyer who can be trusted with any case for any client regardless of how complex it is”. “Paul’s practical advice allows companies to make quick decisions. He is friendly and honest, and does not hesitate to tell it like it is.” When technology-driven disputes arise, legal director Alexander Tsoutsanis comes to the fore: “He is super-bright and generous with his time and knowledge, and evaluates all potential solutions in coming up with a plan. In-house lawyers can move forward without delay thanks to his quick replies.”


The USPs of EP&C include astute deployment of sophisticated internal tools and systems, a commitment to understanding the technology behind the inventions it protects and the ability to see the wider business picture. Managing partner and “excellent patent attorney” Hendrik Jan Brookhuis keeps the firm firing on all cylinders. The “friendly, thorough” Jordi Kox is a “critical, detail-oriented thinker” who produces “exceptionally strong analyses” and has a fantastic track record at the EPO. Completing the line-up is the nimble and perceptive Walter Hart, who finds commercially viable answers to the most complex questions. The civil engineer leverages his industry insight to obtain patents that enhance patrons’ market position.

Freshfields Bruckhaus Deringer LLP

In the words of one foreign associate: “We have worked with Freshfields’ Amsterdam IP team in many highly complicated patent disputes and their level of know-how and customer service are unparalleled.” “It is always a pleasure to work with them,” enthuses another. “They are some of the best and are recommended without hesitation.” Star quarterbacks Rutger Kleemans and Jelle Drok “achieve results that others can only dream of. They have the ear of the court in oral hearings and know how to captivate an audience”. Lately, Kleemans has been representing Novartis in three separate actions against Teva and in preliminary injunction proceedings against Mylan, while also acting for Roche alongside Drok. “Rutger gets to the core of a case instantly, sees what the main arguments are and knows just how to present them.” Drok “gets into the details, sees the full picture and narrows it all down into convincing arguments”. Rising star and “charismatic litigator” Ruben Laddé “really knows his stuff and remembers absolutely everything”. He has lately been assisting Drok in HP in class action litigation. Leading the international patent litigation group, Peter Hendrick has encyclopaedic IP knowledge that frequently makes the difference in pan-European matters.

HGF Ltd 

European outfit HGF debuts in the Dutch rankings of the IAM Patent 1000 this year courtesy of its technically diverse bench, extensive geographical reach – it has 21 bases across the continent and a finely cultivated network of associates – and precision prosecution. In one recent highlight, it is tending to the drafting, global prosecution and strategic counselling needs of anti-microbial technology trailblazer Chemical Intelligence Ltd. With a PhD in chemistry and in-house experience at an oil and gas multinational under his belt, Achim Krebs is a favourite for bespoke, business-minded advice; he also provides farsighted assistance with IP strategy to companies in Asia.

Hogan Lovells

Home to “one of the finest IP litigation teams in Europe”, Hogan Lovells’ Dutch arm also draws judiciously on resources from across the wider firm to carry the day in high-stakes disputes. Many precedent-setting wins bear the fingerprints of department lead Ruud van der Velden, including the successful enforcement of a second medical use patent that was revoked in several jurisdictions. Standing shoulder to shoulder with him are Bert Oosting, Klaas Bisschop and IAM Patent 1000 newcomer Rik Zagers, who all garner rave reviews: “They are my first choice for litigation – their arguments are well written, finely presented and show great attention to detail. They are hardworking and proactive, and they interact with scientific experts exceptionally well.” Oosting is “a great litigator, especially for originators”; Bisschop “is full of ideas and an inspiration to work alongside”; and the star of up-and-comer Zagers is firmly in the ascendant.


The tight-knit patent team at full-service outfit Houthoff thrives on the cut and thrust of hard-fought life sciences and technology disputes that make it all the way to the Supreme Court. Pace setter Thijs van Aerde alone has litigated more than 100 cases before the country’s highest judicial authority; of late he has been duking it out for Fresenius Kabi in a ground-breaking suit against Eli Lilly. The firm has also carved out a niche in plant variety rights – the metier of “truly great and intelligent lawyer” Fleur Tuinzing-Westerhuis. Transactional work is another forte for the group, with Tuinzing-Westerhuis recently advising on the acquisition of 100% shares in Applikon Biotechnology by Getinge. Asset commercialisation and technology transfers fall within the wheelhouse of fellow deal maven Thomas de Weerd; he focuses on the IT sector, which he knows intimately thanks to time spent in-house.


“The first choice for litigation in the Netherlands”, HOYNG ROKH MONEGIER “is effective in court and delivers extremely good results”. The powerhouse enjoys a glittering reputation for its A-to-Z patent offering, as reflected in its fine showing in the rankings. Bart van den Broek provides inspired leadership to the litigation division; the “renowned figure and outstanding lawyer” has “dedicated his whole life to intellectual property and is always on top of every detail”. He and Geert Theuws recently enforced three SEPs relating to 4G on behalf of Philips against several defendants, including ASUS and Wiko. “Geert thinks both strategically and creatively; he is an excellent communicator and a pleasure to work with.” The life sciences is another happy hunting ground for the firm, with the pre-eminent Willem Hoyng and technical all-rounder Theo Blomme bringing home a positive outcome for AstraZeneca in infringement and invalidity proceedings against Sandoz. “Extremely experienced”, Hoyng “understands the court system like the back of his hand and knows everybody worth knowing in the Netherlands”. “First-class advocate” Blomme “is extremely bright, grasps complex technical issues quickly and is very knowledgeable on local laws around pharmaceuticals. Both Theo and Willem are extremely pleasant and are always available”. Meanwhile, biotech superstar Peter van Schijndel and the dextrous, dual-qualified Simon Dack have been defending global veterinary health company Ceva Santé Animale in proceedings against Bayer, in which they have thus far succeeded in having Bayer’s infringement claims dismissed. The “exact and detailed” Frank Eijsvogels is “very successful at winning”, particularly when litigation looms in heavily regulated industries: “He is great to collaborate with, listens to suggestions and has great legal and business knowledge.” Zooming in on the firm’s prosecution service brings Wilbert Derks into focus: “He is always available to answer questions, provide honest opinions and guide clients through the patent jungle. His technical knowledge is extensive and he gives practical, objective advice that considers individual business models and purposes.” In the electrical and mechanical engineering sectors, David Owen and Michiel de Baat have been working on briefs for Intel and Hologic respectively. A US patent attorney and a solicitor of England and Wales, Owen has a cosmopolitan outlook that is hard to come by; while de Baat assists companies in many meaningful ways, from drafting to litigation support. Organic chemist Jeroen den Hartog excels at building, defending and leveraging assets with business goals in mind, providing clear, strategic guidance informed by a deep knowledge of jurisprudence: “He takes a pragmatic, business-centric approach to every matter.”


Recent headline-grabbing instructions prove that the IP team at NautaDutilh is as dynamic as the life sciences and telecommunications concerns whose expectations it consistently meets and exceeds. For instance, it is currently acting for French mobile telephone manufacturer Wiko and parent company Tinno Mobile in the largest set of patent cases to be heard in the Netherlands in this sector. Taking the lead here is Anne Marie Verschuur, who “belongs in the top tier of Dutch litigators. She has a great strategic grip on the cases she runs and has a great eye for detail”. She is assisted by IAM Patent 1000 newcomer Jeroen Boelens, who has an intuitive affinity for the tech and has also been producing great work for medical technology company Heraeus at the District Court of Rotterdam.


A stalwart of the Dutch patent prosecution scene, NLO is “an excellent firm with a team that is always up for a challenge”. Headquartered in Amsterdam, with a further three offices in the Netherlands and two additional outposts in Belgium, it is a trusted ally for ambitious medium-sized local companies and multinationals looking to enter the Dutch market or expand into surrounding territories. It has all disciplines on lock, with Mari Korsten, Bart Swinkels, Arthur Meekel and David Bot holding things down in the life sciences. Having previously worked in-house at Novartis, Korsten “is super-experienced in the biotech field and has great skills in contentious matters”. Drawing on over 25 years at the patent coalface, Swinkels is a strategically creative, commercially aware attorney with a rare aptitude for genetics. Organic chemistry and biochemistry are the specialist subjects of Meekel, a familiar face before the EPO who attends 15 to 20 oppositions and appeals a year. A key partner for start-ups, Bot always puts clients’ ultimate business goals front and centre. Mechanical and electrical engineers Paul Clarkson, Hans Hutter and Maarten Ketelaars also bring something unique to the table. Having served as an examiner at the EPO, Clarkson has a wealth of knowledge on patent office procedures, which gives him an edge on his competitors. Hutter has been assisting Nokia with an infringement action regarding ADSL technology; while Ketelaars’s mechanical, electronic and physics background makes him favourite of innovative players in the medical devices and alternative energy arenas. The in-house insight that fellow physicist Hans Bottema gained at industry-leading companies translates into resolutely business-minded counsel. Companies with overseas interests flock to Catherine Shultz.  Her diverse experience – she has spent time as an oil and gas field engineer and at a US law firm – and European training give her a 360-degree perspective.

Patentwerk BV

Impregnable patent protection and bespoke strategies that further the ambitions of domestic and international clients are the order of the day at nimble boutique Patentwerk. Double ISO certified, the firm is stacked with talented Dutch, Belgian and European patent attorneys hailing from varied technical backgrounds. Founding partner Hein van den Heuvel sets the tone from the top and has mastered the intricacies of niches such as agricultural mechanisation and the food industry. Mechanical engineer Bas Langenhuijsen is “a personable attorney with a great technical, analytical and strategic mindset. He understands a company’s business needs, drafts excellently – and his attention to detail is the icing on the cake”. He has lately been assisting I4F Licensing NV with the development of an extensive patent family relating to floor panels. The team is rounded off by Daan Settels, a biomedical specialist who knows his stuff when it comes to medical technology; and Bram van Oeffelt, who generates value for patrons through smart strategic advice and shrewd portfolio management.

Simmons & Simmons LLP

Simmons & Simmons is “an excellent firm for multinational litigation – its ability to coordinate work across several jurisdictions is most impressive”. Indeed, with 21 offices located throughout Europe, Asia and the Middle East, it has the bandwidth to tackle even the most sprawling suits, to great effect. Its success locally is due in no small part to Bas Berghuis van Woortman, who has spearheaded the Dutch team for over a decade. Highly sought after by corporations such as Gilead, HP and Samsung for his deep well of patent knowledge and trial seasoning, and he “never gets fazed by pressure, no matter how tough the situation – he has seen and done it all before”. Former De Brauw lawyer Oscar Lamme marries robust contentious capabilities with refined technical understanding; he knows exactly what businesses need and how best to deliver it.

Taylor Wessing

“One of the leading litigation firms in Europe”, Taylor Wessing consistently outworks, outwits and generally outlawyers the opposition whenever trouble brews for clients. Its disciplines of choice in the Netherlands are electronics, telecommunications and the life sciences; in the latter space, Judith Krens has been busy representing Pfizer in four proceedings against Hoffmann La Roche in one of the largest biosimilar cases to be heard in recent years. Krens draws on her advanced chemical training and insight from a stint at a US multinational to deliver persuasive, technically sound pleadings. Fellow department co-head Wim Maas has also had a red-letter year, going out to bat for the likes of listed Belgian technology company Barco in numerous infringement proceedings and local construction concern Heijmans Wegen. Together with him on the that matter is IAM Patent 1000 debutante Charlotte Garnitsch, who keeps a cool head in even the most complex cross-border patent suits. “Both Wim and Charlotte are very knowledgeable, super-driven and excellent communicators.”

VO Patents & Trademarks 

“Quality patent assistance and litigation support” is the name of the game at VO Patents & Trademarks, one of the country’s top prosecution shops. With offices in the Netherlands, Belgium and Germany, it has a wide regional footprint; and no technology is off limits to its highly qualified, technically adept practitioners. Anchoring the life sciences division is the multi-talented Otto Oudshoorn, whose broad bailiwick also encompasses chemicals and food technology. He has a knack both for obtaining SPCs and for patent restoration. Fellow chemist Hajo Kraak speaks the language of inventors, thanks to his background in industry, and works seamlessly with in-house teams at the likes of Janssen Pharmaceutica to craft strategies and streamline internal processes. Biology ace Frits Schut is a trusted guide of biotechnology companies and an experienced advocate before the EPO on matters of plant protection. Bernard Ledeboer shines on engineering, high-tech and electronics briefs; the mechanical engineer “has amazing analytical ability, gets to grips with matters down to the last detail” and is great at distilling complex problems into easily digestible solutions. Leo Jessen is the man to call for no-stone-unturned freedom-to-operate analyses and futureproofed protection strategies. Finally, as the former head of patents at two large technology companies, Cees Jansen is intimately familiar with the pressure facing innovators and how best to ease it for them.

Vondst Advocaten NV

A relative newcomer to the Dutch patent scene, Vondst Advocaten has quickly become a repository of trust for major generic pharmaceutical companies in particular. The contemporary boutique has been making waves on the legal landscape for its commercially attuned counsel and redoubtable representation in litigation. Practice co-founder Otto Swens is a “strong patent litigator” who offers “high-quality, cost-conscious support”. His blend of regulatory and patent know-how is appreciated by the firm’s life sciences patrons. Further contentious clout comes from Ricardo Dijkstra and Arvid van Oorschot. “Personable, bright and hands-on”, Dijkstra specialises in medical devices and is celebrated for his flawless coordination of cross-border disputes; while Van Oorschot is pragmatic and results-driven in his approach to pan-European litigation.

Other recommended experts

Transactional aficionado Peter Claassen of AKD operates across the IP spectrum and has the art of commercialisation down to a T. Colleague Martin Hemmer is “a highly talented lawyer with impressive knowledge of foreign legislation and excellent oral skills”. Garnering spirited praise from patrons is HOFFMANN EITLE’s Frodo Nunes Ferro: “He is the ideal sparring partner, challenging everyone’s thoughts and adding value on both a technical and strategic side. Frodo is excellent and the attorney you want by your side.” DeltaPatents BV co-founder Jelle Hoekstra has a cracking electronics-focused practice and knows everything there is to know about process and procedure at the EPO. He also devotes time to training future attorneys for the European Qualifying Examination. Kupecz Intellectual Property’s namesake András Kupecz combines a background in molecular biology with dual qualification as a lawyer and European patent attorney; he is kept busy on multi-jurisdictional litigations and is trusted counsel to many major pharmaceutical companies. At Van Doorne, UPC visionary Sebastian Pinckaers is in his element advising on licensing strategy or immersed in the thrill of cross-border litigation. He has recently been defending the interests of Enermax and Coolergient, the leading manufacturer of cooling systems for computers. The designer of a dynamic, flexible, cost-effective and personal service at Fireball Patents, Pete Pollard is an easy recommendation for patent prosecution. He procures valuable rights with great efficiency, giving his clients the benefit of strong and quick protection. Sources appreciate his “friendly and open-minded approach”. Moïra Truijens of Hoogenraad & Haak devises effective strategies with a deft touch: “She is very efficient and, as a deputy judge at the Court of Appeal in Den Bosch, she knows exactly how to present a case before the court.” Jacques van Breda is an electrical engineer who draws on a deep prosecution playbook to secure watertight protection across the Benelux. A go-to for complex post-grant proceedings, Oxon IP’s Leythem Wall has “exceptional analytical skills”: “His strong knowledge of case law and excellent communication skills make him effective in oral proceedings. Leythem is an invaluable resource and a pleasure to work with, and is highly recommended.”
