In November 2020 the Bundestag reconfirmed Germany’s involvement in the Unified Patent Court (UPC) through an overwhelming vote in favour, marking 2022 as a possible target date for the establishment of the new court; however, details remain sparse and its future is still unclear. In the meantime, most practitioners remain optimistic about Germany’s continued status as a patent litigation hub – although the market is split on whether Brexit’s long-term effects (and in turn, the effects of the United Kingdom’s exclusion from the UPC) will give a boost to the European IP scene or render the continent weaker as a whole. SEP and FRAND issues continue to dominate the courts: the seminal dispute between Nokia, Daimler and a range of intervenors on both the automotive and telecommunications sides is still attracting headlines; while the Federal Court of Justice’s ruling in Sisvel v Haier points to a positive future for SEP owners. Meanwhile, the patent office has been typically busy despite having pivoted to a virtual model; and the volume of patents filed in Germany by both domestic and international players confirms that, whatever the global challenges, innovation in the country is not slowing down.

Firms: infringement

Firms: transactions

Allen & Overy LLP

Allen & Overy’s German IP group is a vital part of its indomitable European offering. Despite its relative youth, the tightly knit team – based in Munich and Dusseldorf – has already earned a glowing reputation for its poised performances in high-profile disputes at the cutting edge of patent law and practice, including those interwoven with SEP and FRAND or SPC and second medical use threads. Its clientele features industry giants from both life sciences and high technology: as an example, the firm is acting for Samsung Electronics – including in a set of preliminary injunction proceedings – under the watchful eye of Jan Ebersohl. He litigates across the technical spectrum, but is especially well known in the car connectivity and Internet of Things fields, and also takes charge of the firm’s global automotive sector group. With a wealth of unfair competition know-how, he has a percipient take on issues that straddle patent and antitrust law. Heading the German life sciences group is 30-year veteran Joachim Feldges, who has lately been advising Bayer on the German components of two cross-border litigations in relation to veterinary products. He coordinates international patent strategies for pharmaceutical, biotechnology and medical devices players, and is also a qualified arbitrator and mediator. Completing the line-up is all-rounder Jens Matthes, whose remit covers the full range of IP rights, as well as unfair competition and employee invention law, and whose contentious caseload is complemented by a steady contract negotiation and corporate transactions practice. “Jens is a very dedicated adviser and one of the very best German commercial IP lawyers. He displays a profound understanding of business requirements and his proposals are always very helpful.” “He assists with some of the most critical projects through his tremendous expertise, smart contract interpretation skills and a highly efficient negotiation style that never is intimidating, but always leads to great solutions.”

ARNOLD RUESS Rechtsanwälte Partnerschaft mbB 

Competitors single out Arnold Ruess as one of the premier IP boutiques on the German stage. Many landmark cases bear its fingerprints: recent examples include representation in a cross-border infringement suit for Sanofi; a ground-breaking FRAND action for Sisvel – one of the first cases of its kind since the landmark Huawei/ZTE judgment was handed down; and a boundary-crossing connected cars dispute for Nokia, which involved the first instance of an anti-anti-suit injunction in Germany. Leading on the latter two precedent-setting matters is Cordula Schumacher, a “top-rate litigator” whose advice is “clear, pragmatic and realistic”: “She never promises anything that cannot be delivered, but goes above and beyond to get the best possible outcome for her clients. She also understands the client’s commercial goals and adjusts her approach based on feedback.” Spearheading the Sanofi campaign and giving the firm its name is “IP litigation star” Bernhard Arnold: “He is a great counsel to have on your side and manages an efficient team. He is not afraid to come up with creative solutions and is internationally well connected.” A third gladiator in the mix is Arno Riße, whose metier is high-technology litigation; he recently defended US software and hardware player Adtran against a patent infringement claim. “Arno is one of the most outstanding attorneys in his field,” reports one source. “He knows all the tricks of the trade of modern patent litigation. There is hardly a notable patent matter in the German courts which does not name Arnold Ruess on one side of the docket sheet, and most often Arno is one of the attorneys in the trenches.”

Baker McKenzie

The German contingent of global juggernaut Baker McKenzie is modest but mighty. Its patent litigation group was put firmly on the map in 2013 when dual-qualified attorney at law and patent attorney Jochen Herr came on board; since then, he has done a superb job in building out the practice, which is now engaged on a wide range of both infringement and validity disputes. Key clients include fintech leader Giescke & Devrient, which it recently represented in a high-profile patent infringement spat against the US government; and Real-D, whose 3D cinema technology it has defended in a patent infringement suit and in parallel opposition proceedings. Herr has a technical background in mechanical and process engineering, and an affinity for issues at the intersection of patent and antitrust law. Anchoring the non-contentious side is Constanze Ulmer-Eilfort, who was previously managing partner across both the German and Austrian offices. She has a flair for the fine print of collaboration, licensing and R&D agreements, especially within the life sciences.


Bardehle Pagenberg set the precedent for the hybrid model in Germany, having played host to both patent attorneys and attorneys at law since as early as the 1980s, and it continues to enjoy first-mover advantage today: “Bardehle Pagenberg is one of the top patent litigation firms in Europe. Its lawyers are extremely knowledgeable and capable, and their grasp of both the legal and technical issues is extraordinary. The good business sense they bring to the table is invaluable; their communications are consistently timely; and they are open to discussing new ideas and impress with their strategic thinking.” On the prosecution side, Joachim Mader is the resident mechanical engineering and automotive maven. He is a worthy advocate in oppositions; regularly collaborates with attorneys at law to resolve infringement and nullity proceedings; and manages hefty portfolios – such as that of global auto parts company Aptiv – with a deft touch. For electronics, the names to note are Tobias Kaufmann and Johannes Lang. A stint in-house at a leading electronics company means that Kaufmann speaks the language of innovators such as Samsung Electronics and Qualcomm, which he recently represented in EPO opposition proceedings. Co-managing partner Lang is a prolific filer across the electronics, IT and telecommunications fields whose recent credits include representing adidas and Apple at the EPO. Assisting him on the former mandate was Christian Haupt; whereas his partner on the latter was Christof Karl. Haupt is highly sought after for his infringement and validity opinions – in particular, in the mechanical engineering, computer-implemented inventions and electronics spaces. Telecommunications expert Karl – who has also been representing Japan Tobacco and Nintendo in administrative proceedings – is truly multi-talented: dual qualified as a patent attorney and attorney at law, he is also licensed to practise law in both Germany and New York and speaks four languages fluently. Similarly dual-qualified is co-managing partner Johannes Heselberger, who has recently gone out to bat for Amgen in a high-profile cross-border patent battle alongside colleague Tilman Müller-Stoy. Heselberger brings keen technical insight gained through his academic training as a physicist to his diverse patent litigation practice; while Müller-Stoy’s broad wheelhouse encompasses everything from cross-border patent disputes to patent-related antitrust law and the creation and enforcement of licensing programmes – especially where SEPs and FRAND issues are concerned. Working across the high-technology, automotive and pharmaceutical sectors is elder statesman Peter Chrocziel, who excels in cross-border proceedings and provides unparalleled guidance on US matters, thanks to his qualification to practise in New York. He juggles his contentious work with a thriving IP transactional practice and is currently putting his entire skillset to good use in counselling semiconductor solutions company SK Hynix through a cross-border infringement dispute, while also advising it on related licensing and antitrust concerns. Equally capable in cross-border contexts is Alexander Haertel, who recently made the switch from Kather Augenstein and has an enviable track record in high-profile litigation across all key European venues. Finally, firm namesake Jochen Pagenberg is an illustrious figure who has litigated in the electronics, telecommunications and automotive fields for more than three decades and is an adroit coordinator of multi-disciplinary international teams.

Bird & Bird LLP

As a central cog in the firm’s global IP machine, Bird & Bird’s German practice provides an A-to-Z patent service – from EPO oppositions and Patent Cooperation Treaty filings to representation in patent infringement proceedings – to the likes of Edwards Lifesciences, Sandoz, Nokia and healthcare company B Braun Melsungen. Acting for Edwards Lifesciences are Anna Wolters-Höhne and Boris Kreye, who relish the cut and thrust of cross-border litigation. The pharma-focused Wolters-Höhne has appeared in numerous headline-grabbing preliminary injunction proceedings; while Kreye’s broad practice sees him involved in everything from pharmaceutical battles to SEP and FRAND disputes. Colleague Felix Rödiger has also featured in a number of FRAND firsts in Germany and is a smooth broker of litigation, arbitration and licensing agreements across Europe and the United States. Acting for Sandoz, as well as for Broadcom in a series of infringement, opposition and nullity proceedings, is Oliver Jan Jüngst, a “clear and concise communicator” with “a pragmatic approach to litigation”: “He is clearly well respected by judges and opposing counsel, and is an impressive advocate.” Nokia turns to German department head and international IP co-head Christian Harmsen, whose “valuable, business-minded advice” leads to “insightful strategic decision making”; while B Braun Melsungen has both Matthias Meyer and Daniela Kinkeldey on its side. Equally at home at the deal table as in the courtroom, Meyer also serves as head of the China desk in Germany; while Kinkeldey draws on a doctorate in chemistry in her pharmaceutical disputes work. Meanwhile, patent attorneys Felix Landry and Michael Alt are on hand for prosecution briefs. PhD physicist Landry is a telecommunications and IT specialist who has lately carried out EPO filings and oppositions for the likes of Garmin and Airbus. The contentious experience of PhD biochemist Alt stretches to acting in nullity proceedings in court and consulting on cross-border infringement actions; he also recently appeared in cancer therapy-related opposition proceedings on behalf of Zentiva.


“One of the best-established and most prominent IP outfits in Germany”, according to competitors, BOEHMERT & BOEHMERT is home to some 70 dedicated professionals – including both patent attorneys and attorneys at law – who can meet and exceed every patent need of its discerning clientele. Key patrons on the prosecution side include blockchain innovator Black Gold Coin, biotechnology company Gennova Biopharmaceuticals and research institution King Faisal Specialist Hospital & Research Centre. Assisting Black Gold Coin is physicist and portfolio manager Dennis Kretschmann, whose glittering academic career saw him study in Germany, the United States, the United Kingdom and Italy. The latter two clients are safe under the wing of PhD biochemist Markus Engelhard, a farsighted strategist and EPO advocate who comes highly recommended by the market. Their fellow patent attorneys are physicists Heinz Goddar and Christian W Appelt. Elder statesman and IP strategist Goddar shares his wisdom by teaching patent and licensing law at the University of Bremen and the Munich Intellectual Property Law Centre; while Appelt has a contentious focus, regularly acting in opposition and nullity proceedings and supporting on infringement suits. He is a trusted adviser to Chinese, US and especially Japanese clients, having spent time in the IP department of Sony Corporation in Tokyo, as well as in private practice in Osaka. Attorneys at law Michael Rüberg and Carl-Richard Haarmann have it all covered on the contentious front. Rüberg is a law PhD whose recent credits include an ongoing set of disputes on behalf of Aeritas relating to mobile boarding and location-based services within the aviation industry; while Haarmann is a savvy portfolio manager who also appears in infringement battles for the likes of JVC.

Braun-Dullaeus Pannen Emmerling 

Commercially focused boutique Braun-Dullaeus Pannen Emmerling arrives in the IAM Patent 1000 this year on a wave of client commendations: “Its advice is clear, well thought out and applicable across multiple jurisdictions; and the team is detail oriented, sensible and shows great judgement.” With legal and technical expertise in abundance, it has made annulment actions something of a specialty: it is currently involved in 5% of all such pending proceedings in Germany. In the spotlight is physicist Friedrich Emmerling, who has been appearing in oppositions and drafting applications for Huawei, while also representing adidas at the EPO. “Friedrich’s attention to detail is immaculate and he recalls all of the issues straight away, so you can discuss any point with him instantly. He is one of the best German patent attorneys out there and has a good feel for what will work before the courts.” Fellow namesake and physicist Karl-Ulrich Braun-Dullaeus is “an impressive analyst” with “broad knowledge of SEP procedure” and the ability to handle a challenging number of cases in parallel.

Clifford Chance

The small but perfectly formed German IP group at Clifford Chance draws judiciously on the wider firm’s sweeping global network and complete command of law to hammer out the rights results on consequential cross-border mandates. Patent infringement, nullity and unfair competition proceedings; IP-rich M&A deals – it has seen and done it all for its loyal following of pharmaceutical, high-technology and telecommunications multinationals and dynamic domestic concerns. “Efficient cooperation, responsiveness and time and cost-effective recommendations” are hallmarks of its service. Running the show is Claudia Milbradt, who leads both the German IP group and the German tech group. Having dispensed globally minded IP advice across the contentious/non-contentious divide for more than two decades, she has developed “an increasingly respected patent litigation practice”, according to peers.


With both patent attorneys and attorneys at law on deck, and a total headcount of 22 partners, COHAUSZ & FLORACK stands as one of Germany’s elite patent firms. “I have never encountered a smarter, more effective, more versatile, more cost-efficient group of lawyers,” marvels one client. “They are sensitive to every issue and thoughtful in addressing them, and maintain the highest ethical standards. Their evaluation of patents holds up without failure; and they are great in enforcement actions as well.” It is currently assisting leading European paint and varnish manufacturer Brillux with a sprawling set of EPO oppositions – a matter orchestrated by chemist Arwed Burrichter. A PhD earned in California and a stint in the IP litigation group of a New York law firm have given him keen insight into US patent procedure. Gottfried Schüll, Philipe Walter and Christoph Walke have electronics on lock. Communications and video compression technology ace Schüll “created the gold standard for patent pool licensing” and has acted in upwards of 750 contentious patent matters. Electrical engineer Walter has won many fans among Germany’s Mittelstand for his canny portfolio development and regularly plays a role in battles between smartphone companies, set-top-box manufacturers and automotive suppliers. Walke has lately been assisting Sharp Corporation in infringement proceedings at the Mannheim and Munich Regional Courts, and receives rave reviews: “Christophe is clearly in Germany’s top patent attorney league. He makes life as easy as possible for in-house teams, with his clear strategic recommendations and well-prepared drafts. His technical expertise is outstanding and he puts himself into the shoes of clients in order to understand their business needs.” Mechanical engineering and mining technology are fortes for Andreas Thielmann, who has spent almost 30 years in the game and holds a post as an honorary judge in the Senate for Patent Attorney Matters at the Federal Court of Justice in Karlsruhe.


df-mp enjoys a stellar reputation as a prosecution shop par excellence, with special proficiency in life sciences and electrical and mechanical technology. “A relationship with df-mp is built on mutual trust and respect, high professional standards and ethical conduct,” reports one client. “They listen actively; bring curiosity, entrepreneurship and creativity to the table; and always communicate clearly and concisely.” Teva recently engaged the firm on SPC-related nullity proceedings; while Biogen has enlisted it for a set of EPO oppositions. Acting on the former brief is biotechnologist and firm co-founder Ulrich Dörries, whose varied diet includes drafting and prosecution, EPO advocacy and SPC advice. Fellow co-founder Sandra Pohlman is looking after Biogen; she heads up the biotechnology and pharmaceutical group, has a flourishing DNA and CRISPR practice, and is qualified to act before the USPTO. Also active on the life sciences side is chemistry head Elisabeth Greiner, a “proactive and strategic thinker” and “a diligent and pleasant person to work with”. For electronics and mechanics, dial up physicists Dominik Ho and David Molnia, who recently acted for Unwired Planet in a series of infringement and nullity actions as part of its seminal dispute with Huawei, LG, Samsung, HTC and Google. Ho is a dual-qualified patent attorney and attorney at law who lately represented Sonos in a spat with Google over smart speakers; while firm co-founder Molnia is a qualified US patent agent whose other recent highlights include acting for Nokia in an infringement battle against Daimler.

DLA Piper

Growth is the central narrative at DLA Piper, which has picked up a slew of new instructions over the last 12 months, including infringement proceedings on behalf of Dell, Microsoft and HP. Audio electronics company Harman is another pioneering client which the firm is representing in a series of suits, including its intervention in the ground-breaking Broadcom v BMW case. Leading on this is practice head Markus Gampp, who “provides consistent, creative and effective counsel”: “He is proactive in considering upcoming issues and is very knowledgeable on the substantive legal issues, while also considering the business realities.” Life sciences don Philipp Cepl has been busy advising medical devices leader Medtronic on patent enforcement and preliminary injunctions. “He is a standout patent litigator with immense procedural experience and sound judgement”; “His advice is practical and he never loses sight of clients’ economic interests and goals.”

Dompatent von Kreisler Selting Werner

Arriving in the IAM Patent 1000 thanks to effusive peer feedback, this “reliable stalwart” provides a holistic offering to a legion of multinationals across the chemistry, biotechnology, electronics and telecommunications fields. It plays host to both patent attorneys and attorneys at law, filed more than 1,000 European patents in 2019, has around 320 EPO oppositions on its plate at present and regularly features in must-win litigation. The twin pillars of its practice are Christoph Schreiber and Alexander von Kirschbaum, whose tenures with the firm are both approaching the 25-year mark. Chemistry PhD and seasoned portfolio manager Schreiber has the life sciences down cold; while mechanical engineer von Kirschbaum effortlessly gets to grips with the tech in fields as varied as medical technology and automotive.

DREISS Patentanwälte PartG mbB 

Domestic SMEs and multinationals from the United States, Korea and China flock to the doors of patent attorney outfit DREISS for its precision prosecution. Through smart collaborations with other legal teams, it also tackles major disputes for the likes of illustrious Japanese innovator Pioneer and packaging leader Storopack. First among equals is process engineering ace David Sinz, who “shows high technical expertise, maintains a good overview of matters and provides fast support in litigation”. Alongside his portfolio management workload, he recently represented Philip Morris International in opposition proceedings alongside colleagues Thomas Knapp and Andreas Pfund. The former has valuable industry experience from his time as an aerospace engineer and a wide knowledge base encompassing everything from medical technology to machine tools; the latter is a semiconductor nanophysics PhD who is similarly fluent in myriad technical disciplines, having worked as a solid-state physics research associate in Switzerland. This broad technical acumen is shared by electrical engineer and Spanish speaker Michael Kröhnert, who is steadily growing his AI practice.


While perhaps best known for its hybrid practice in the United Kingdom, EIP’s German IP litigation squad is a formidable force. This year it has continued to act for Conversant – both on the German component of its sprawling pan-European litigation against Huawei, ZTE and LG, and in a brace of hotly contested connected cars disputes with Daimler and Tesla. Avago has also engaged it in litigation against Daimler; while Broadcom has sought it out for out-of-court portfolio analysis and infringement advice. Providing input on all of these briefs is Florian Schmidt-Bogatzky, an “extremely creative and hardworking attorney who can quickly master new technologies”. Leading on the Conversant matter and heading up the Dusseldorf office, Christof Höhne litigates across the electronics, pharmaceuticals and mechanical engineering industry and regularly pairs up with patent attorneys to defend clients in EPO oppositions.

Eisenführ Speiser 

The patent attorneys and attorneys at law at Eisenführ Speiser draw on “in-depth knowledge of both technical and legal matters” to provide an inter-disciplinary, commercially focused service. One recent highlight was its representation of NPE Sisvel in patent infringement proceedings against Xiaomi – a high-profile matter to which attorneys at law Volkmar Henke and Tilman Müller and patent attorney Jochen Ehlers made vital contributions. “Amiable and well respected” among major communications players, Henke skilfully handles both infringement disputes and licensing mandates, with “a notably high success rate”. Müller’s remit encompasses patent infringement and nullity proceedings, SEP and antitrust-related issues, IP-related arbitrations and contract negotiation. Prosecution, litigation and transactions all fall within the purview of telecommunications and semiconductor expert Ehlers, who also comes equipped with FRAND and SEP know-how. Other esteemed patent attorneys on deck include electrical and telecommunications engineer Klaus G Göken – an IP strategist and litigation sage with rich industry experience from his previous career in the semiconductor field at Siemens and IBM; and life sciences whizz Manuel Söldenwagner, who recently represented fragrance and flavours company Symrise in a series of oppositions. “Manuel is efficient, organised and sensitive to client needs,” reports one happy patron of 10 years’ standing. “I have nothing but praise for his work, responsiveness and quality advice.”

Freshfields Bruckhaus Deringer LLP

Competitors observe that Freshfields’ German patent group is “a collaborative and close-knit team which is involved in many of the biggest cases on the market, working day and night to reach winning solutions”. From five bases across the country – and with robust support from the firm’s global network – its practitioners coordinate multi-jurisdictional litigation and negotiate IP-rich transactions with finesse. Tenacious litigator Frank-Erich Hufnagel heads up the Dusseldorf office and has been with the firm for over two decades – his highlight reel includes acting for the likes of Ericsson and Lenovo in SEP disputes and advising Novartis on pharmaceutical and biologics patents. Fellow courtroom warrior Wolrad Prinz zu Waldeck und Pyrmont also has a diverse practice and often works at the intersection of patent and competition law. His linguistic capabilities in English, French and Russian make communication a breeze for international clients. Captaining the Hamburg IP practice is Jochen Dieselhorst, a transactional maven whose stomping grounds are the IT and life sciences sectors. Notable briefs include shepherding M&A deals over the line for the likes of Merck KgaA and Boehringer Ingelheim; and counselling BioNTech SE on covid-19 vaccine-related licensing and collaboration agreements with Pfizer.

Gleiss Lutz

Gleiss Lutz provides a reassuringly holistic patent offering: cross-border litigation, strategic advice and IP-related transactions and licensing are all dispatched with alacrity and poise. As one of Germany’s largest corporate law firms, it has an edge on multi-faceted mandates, making it a persuasive one-stop shop for its multinational clientele. Versatile litigator Matthias Sonntag acts in disputes across the industry spectrum, although telecommunications is a stronghold. He also assists on IP-related M&A projects, bringing international insight from time spent on secondment at an IP law firm in New York. He is joined on the disputes side by elder statesman Thomas Bopp, who has been with the firm for almost three decades and specialises in healthcare battles. Pure-play transactions lawyer Herwig Lux changes the game for life sciences and automotive titans through the licensing agreements and M&A deals he gets inked for them.

Grünecker Patent Attorneys and Attorneys-at-Law 

Hybrid firm Grünecker “continues to dominate” in prosecution, while steadily growing its reputation in the contentious space through its involvement in a range of automotive and electronics disputes. “It shows sound judgement and a deep understanding of the technology, and delivers exceptional results while billing very efficiently,” report clients; while competitors attest that it is “very professional, rigorous and well prepared, and has great experience in oral proceedings at the EPO”. Its SEP know-how is another USP; as is its sensitivity to the specific needs of companies from the United States and China. The group’s electronics and software experts – who act for the likes of Microsoft and Samsung – include patent attorneys Anton Pfau, Moritz Höffe, Reinhard Knauer, Thomas Eickelkamp and Peter Miltényi. The “efficient and capable” Pfau has impeccable academic credentials: he holds a doctorate in physics and studied semiconductor technology at the University of Berkeley, California. Höffe is fluent in disciplines ranging from physics and software to medical devices and mechanical engineering; oppositions and infringement and licensing opinions are his bread and butter. Computer scientist Knauer devises futureproofed IP strategies for some of the world’s leading high-technology companies; electrical engineer Eickelkamp has an intuitive grasp of the essence of inventions in spaces as diverse as nanotechnology and renewable energy; and physicist Miltényi has a unique perspective as a dual-qualified German patent attorney and Spanish patent agent. For life sciences instructions, look no further than microbiology PhD Heike Vogelsang-Wenke, a trusted ally of major biotechnology and pharmaceutical companies for the last 25 years. The litigation division is jointly led by attorneys at law Ulrich Blumenröder and Bernd Allekotte, both of whom shine in the heat of cross-border litigation. Blumenröder is a law PhD and a UPC expertwho has spent almost 30 years at the patent coalface; and SEP and automotive sector specialist Allekotte has a flair for matters at the intersection of patent and antitrust law.

Hannke Bittner & Partner

With offices in Regensburg, Koblenz, Trier and Kassel, IP boutique Hannke Bittner & Partners offers a cradle-to-grave patent service to a varied group of innovators, including the likes of Volkswagen. Its “trustworthy and efficient” practitioners “communicate well to ensure clients have all the information they need to make the best decisions”; “their patent applications are always well drafted and thorough”. Name partner Bernhard Bittner is a dual-qualified patent attorney and attorney at law and “a relentless fighter in opposition proceedings – he is always well prepared and presents convincing arguments”. He shares his physics specialism with patent attorney Melanie Pfeuffer, a prolific prosecutor and EPO representative who can instantly parse the complexities of everything from computer-implemented inventions to automotive technologies.

Hengeler Mueller

Hengeler Mueller’s patent division delights and reassures with its “consistently high-quality work”, “proactive guidance” and total mastery of even the most challenging patent infringement suits. SEP issues and cutting-edge technologies are increasingly a focus: in the last year alone, it has intervened in Germany’s most hotly discussed dispute (Nokia v Daimler) on behalf of Renault; duked it out for France Brevets and IPCom in a set of infringement actions against Apple; and represented General Electric subsidiary Concept Laser in a series of 3D-printing-related matters. Acting on all these cases is the “smart, practical and results-oriented” Wolfgang Kellenter. Whether in litigation or licensing scenarios, the patent infringement group head “quickly grasps the facts, asks intelligent questions and delivers solutions promptly. He puts himself in his clients’ shoes and sees their problems before they even see them themselves”.

Heuking Kühn Lüer Wojtek

The thriving patent litigation practice at full-service firm Heuking – which handles both infringement and nullity proceedings in all venues at home and in Europe – is bolstered by abundant ancillary know-how in other relevant areas, such as trade secrets, antitrust and wider commercial law. Its international profile has recently expanded, with increasing numbers of instructions pouring in from across the continent and beyond to complement its domestic caseload. Clients which have lately benefited from its staunch representation include telecommunications company Swissphone, in infringement proceedings; French medical technology company ECHOSENS, in a dispute which has seen parallel proceedings take place in Austria and India; and Dutch lawn sport surfaces leader Sisgrass, in both infringement proceedings and parallel EPO oppositions. Running point on these is department head Anton Horn, who has a cosmopolitan outlook from a stint at a corporate law firm in Mexico City; life sciences and high technology are his happy hunting grounds. Alongside him on the latter two mandates is Sabine Dethof, an enforcement ace who knows both the medical devices and mechanical engineering fields like the back of her hand.


Established in 1892 and with more than 150 professionals on deck today, HOFFMANN EITLE stands as one of the continent’s largest, most storied IP firms. With offices in three German cities and additional outposts in the United Kingdom, the Netherlands, Italy and Spain, it is within easy reach of its international clients, which appreciate its holistic patent service and special expertise in EPO oppositions. “The team is meticulous, focuses on understanding clients’ needs and provides constructive suggestions in difficult situations. The attorneys are relaxed to work with and concentrate on the work product, and not on prestige.” For mechanical engineering issues, Claus Thomas Becher and Frank van Bouwelen are the first port of call; while Veit Peter Frank has it all covered on the electrical engineering side. Becher recently put in the hours in EPO oppositions for Novo Nordisk in relation to its medical devices and for PopSockets in relation to its innovative mobile phone accessories. Dual qualified as a German and Dutch patent attorney, van Bouwelen is the architect of fruitful prosecution programmes across Europe, the United States and the Far East; while Frank is a tenacious EPO advocate with a focus on telecommunications. The sizeable life sciences team includes Joachim Renken, Morten Garberg, Joseph Taormino, Peter Klusmann, Thorsten Bausch, Leo Polz and Andreas Stefferl. Biotechnologist Renken recently appeared in EPO oppositions on behalf of the University of Tokyo; while Garberg’s diverse pan-European chemistry practice is enhanced by his dual qualification as a British and German patent attorney and fluency in English and Danish. Microbiologist Taormino co-heads the biotechnology group and brings deep technical acumen gained through a PhD from the John Hopkins University in the United States. Chemistry group co-head Klusmann has an intuitive grasp of everything from pharmaceuticals to polymers; while fellow co-head Bausch is hailed as “a widely experienced technical expert and one of Germany’s go-to patent attorneys”. Biochemist and seasoned EPO representative Polz earns plaudits as a “trustworthy global adviser”. Neurobiologist Stefferl is a valuable resource for start-ups, thanks to time spent nurturing early-stage biotechnology companies as an investment manager. The attorneys at law to note are Dirk Schuessler-Langeheine and Clemens Tobias Steins, each of whom beats a path through the European patent jungle for Japanese clients and regularly delivers advice in Japanese. Schuessler-Langheine puts in resonant performances in proceedings on home soil and coordinates them worldwide; while Steins concentrates on high-rolling IP transactions and licensing.

Hogan Lovells

Hogan Lovells’ German patent group ranks firmly among Europe’s crème de la crème, as reflected in the glowing client feedback it attracts: “They fully grasp new ideas and have great attention to detail. The lawyers are technically sharp and highly skilled, and their arguments persuasive and clear.” Must-win multi-jurisdictional litigation is a forte: as an example, Stephan Neuhaus and Andreas von Falck are currently fighting the corner of F Hoffmann-La Roche in cross-border patent infringement and revocation proceedings. Both have an affinity for pharmaceutical disputes, but are also known for their involvement in telecommunications and high-technology battles respectively. Von Falck’s other recent credits include a semiconductor-related dispute on behalf of Ford alongside colleague Steffen Steininger, who has litigated upwards of 250 cases throughout his career; he is “careful to present a full and accurate picture of every case and always listens to the needs of clients”. He recently collaborated with Martin Fähndrich in a series of proceedings for Koch Group subsidiary Molex; with dual academic qualifications in engineering and law, Fähndrich makes light work of technically dense cases and is singled out by the competition as a standout practitioner. Miriam Gundt is likewise acclaimed by clients as “friendly, legally astute, technically adept and one of Germany’s top IP litigators”; she has a wide remit, but focuses on pharmaceutical – and especially SPC-related – disputes. Clemens Plassmann showcases similar dexterity in his practice: his recent credits range from acting for healthcare company Medinol in a major nullity action to representing HTC in both a FRAND-related dispute and a patent validity suit. Alongside him on the latter mandate is Henrik Lehment, an authority in the telecommunications, consumer electronics and automotive fields who is “experienced, hardworking, responsive and skilled at developing winning strategies”. Also handling telecommunications cases – including those with FRAND components – as well as automotive and life sciences disputes is the “client-oriented and reliable” Benjamin Schröer: “His deep knowledge of SEPs, patent litigation and patent licensing enables him to give high-quality, up-to-date advice in ever-changing areas of law.” Dual qualified as a European patent attorney and attorney at law, fellow all-rounder Alexander Klicznik knows all the right moves both in court litigation and in EPO opposition proceedings. For licensing and technology transfer issues, meanwhile, no IP-related agreement or transaction is beyond the capabilities of Hamburg managing partner Christian Stoll.


As the largest IP litigation boutique in mainland Europe – and one of the most successful outfits of its kind anywhere in the world – HOYNG ROKH MONEGIER has won the loyalty of a slew of household names in the life sciences and high-technology sectors. Clients and competition agree that it sits at the apex of the German patent litigation scene. “The team is responsive, does not over-engineer cases and streamlines litigation efforts. The range of scientific expertise on show is unique.” Leading the charge is Martin Köhler, who has spent more than 20 years defending the interests of his sector-diverse clientele to the hilt in court; he is responsible for the firm’s ongoing representation of Samsung in both infringement and nullity proceedings. Teaming up with him on this are Tobias Hahn and Mirko Weinert. Hahn’s fine-grained understanding of FRAND and unfair competition law proves invaluable for numerous telecommunications, high-technology and automotive companies; while Weinert is called on by the likes of Huawei and Gilead for his “excellent knowledge of European patent law, technology and the German legal system”. Leading on matters for Huawei, Tobias J Hessel is intimately familiar with US patent law and “provides clear guidance, is willing to take educated risks and puts the interests of clients first, second and third”. The Gilead mandate was run by Christine Kanz, an adroit coordinator of cross-border pharmaceutical and biotechnology disputes across Europe and beyond. For telecommunications battles, FRAND and SEP expert Kay N Kasper is “one of the best to turn to”: he recently represented Telekom Deutschland in a set of sprawling infringement proceedings, with support from a group of hotshot attorneys at law including Stefan Richter and Klaus Haft. Richter also focuses on telecommunications and earns praise for his “solid and well-tested litigation style”. Qualified physicist Haft has been busy advising Airbus on patent protection and enforcement, and representing Intel in globe-spanning litigation proceedings: “He is intimately familiar with worldwide legal systems and commands the attention and respect of judges. He is an excellent strategist, is very personable and can quickly grasp the technology.” Two luminaries who continue to guide the firm and devise astute global litigation strategies are Christian Osterrieth and Thomas Reimann. The former has been litigating for 35 years and knows French patent procedure inside out; while the latter is an eminent figure of almost 50 years’ standing who manages global disputes with a sure touch, while also taking part in German and EPO opposition and nullity proceedings.

Jones Day

US player Jones Day has its flag firmly planted in the German market and provides the full spectrum of patent services to a high standard, although competitors highlight the litigation group as deserving of special mention this year.

Taking care of BMW’s prosecution needs are Michael Wallinger and Michael Platzoeder; while attorney at law Thomas Schachl – a seasoned patent litigator and orchestrator of parallel proceedings – has been counselling the auto manufacturer in litigation. Namesake Wallinger has been in the game since the 1980s and is lauded as “one of the true greats in the German patent space”; while high-technology group Platzoeder is a physicist who previously worked in the IP department of global semiconductor supplier Infineon Technologies. Heading up the chemistry and pharmaceutical group are co-founders and doctors of chemistry Mathias Ricker and Holger Tostmann. Ricker joined forces with Platzoeder on the Fresenius work, which involves strategic advice, opposition proceedings and the drafting of AI-related patent applications; while IAM Patent 1000 newcomer Tostmann has an enviable success rate in oppositions and is managing Immunolight’s portfolio. Also appearing in the rankings for the first time are chemist Christiane Maxien, who joined the partnership in 2018; and biotechnology doyenne Cornelia Oetke, who has a flair for advancements such as small molecules and antibodies, and recently assisted Boehringer Ingelheim with patent prosecution and opposition proceedings.

Weickmann & Weickmann PartmbB 

For almost 140 years, Weickmann & Weickmann has offered a technically proficient, strategically minded service from its base in Munich, the patent prosecution capital of Europe. Its 40-plus patent attorneys speak the language of inventors and have an intuitive understanding of the commercial needs of modern businesses. Anchoring the mechanical engineering and electronics sides is Markus Herzog, who has spent more than 25 years prosecuting and defending patents; before which he spent time in academia, imparting his solid-state physics knowledge and developing  semiconductor technologies. His counterparts on the life sciences front are biochemists Wolfgang Weiß and Christian Heubeck. Weiß has been practising for almost three decades and splits his time between dispensing strategic advice and masterminding EPO oppositions; while the technically and commercially adept Heubeck lends his hand to everything from routine filings to freedom-to-operate analyses and licensing advice.

Wildanger Kehrwald Graf von Schwerin & Partner mbB 

Competitors speak highly of Wildanger as a “strong firm which makes a good impression in court hearings”. It has carved a notable niche representing SEP owners, but disputes of every flavour are handled with finesse by its supremely capable, diversely qualified team of 13 lawyers. Spearheading the group’s SEP efforts is Peter-Michael Weisse, who was behind some of the first post-Huawei v ZTE judgments and played a key role obtaining the first German anti-anti-suit injunction against a Chinese anti-suit injunction. Also working in this space is Alexander Reetz, who joined the partnership in 2019 and regularly appears in cross-border disputes with FRAND licensing implications; and Joerg Schmidt, an IP all-rounder who is especially noted for his facility for SEP-related telecommunications suits and thriving medical technology practice. Roland Kehrwald and Eva Geschke are similarly versatile: 30-year veteran Kehrwald advises and litigates across the IT, genetic engineering and medical technology sectors; while Geschke has a wealth of scientific know-how and is hailed by peers as “a strong litigator who knows what she’s doing”. Also with broad horizons, but with a focus on the biotechnology and pharmaceutical spheres, is Wolf Graf von Schwerin, who has litigated countless consequential cross-border cases throughout his career, including many which have resulted in landmark decisions.

Wuesthoff & Wuesthoff

Established in 1927, Wuesthoff is the longstanding partner of ground-breaking innovators in spaces including consumer goods, electronics and medical technology; software has also become a growing focus of its practice, not least thanks to the efforts of Rainer Röthinger and Rainer Gunzelmann. Physicist Röthinger draws on a breadth of experience which includes time spent in the semiconductor research department of Daimler-Benz and at a US law firm; while electrical engineer Gunzelmann’s pre-Wuesthoff career included a period as a software engineer for MAN Technologie and a stint at Siemens, whose Beijing patent licensing centre he established. Fellow Siemens alumnus Bernhard Thum formerly headed up its patents and standards department; today he is a prolific drafter and prosecutor of patents in the mechanical and biomedical engineering spheres. For biotechnology, chemistry and pharmaceuticals issues, Hendrik Wichmann is the one to call. As comfortable managing sprawling portfolios as he is appearing before the EPO’s Opposition Division and Boards of Appeal, he has also intervened in cross-border litigation within the food chemistry and therapeutic antibody fields; plant varieties are a further specialism.
