France

Change is afoot in France, thanks to the roll-out of President Macron’s much-discussed Action Plan for Business Growth and Transformation. As a result of the reforms, opposition proceedings have for the first time become part of the French patent granting process, rendering the system more rigorous and strengthening the resultant rights. While this is generally viewed as a positive step and has brought in new work for French attorneys, some are concerned that the introduction of an extra step to the process may lead inventors to bypass France entirely and head straight to the European Patent Office (EPO). Whether this pattern ultimately emerges remains to be seen. Question marks still hang over the fate of the Unified Patent Court (UPC) and French patent practitioners – much like their counterparts elsewhere on the continent – continue to wait and see how things play out.

Allen & Overy LLP

The Paris office of pan-European juggernaut Allen & Overy is well equipped to tackle high-stakes disputes involving high technology and life sciences, demonstrating impressive sector knowledge in both areas. Across these two broad fields, the firm prides itself on being the French leader when it comes to preliminary injunctions: it was involved in 75% of all such actions carried out in the jurisdiction last year, many of which were precedential in nature. David Por is the figurehead on the high-technology side, recently fighting the corners of Samsung Electronics France and Archos. He is an expert at the intersection of IP and competition law. On the life sciences side, Laëtitia Bénard leads the charge and regularly appears in high-profile international patent suits, most recently on behalf of Novartis. The co-head of Allen & Overy’s worldwide life sciences group is noted for her unique ability to advise on pharmaceutical regulatory issues and their interplay with intellectual property.

Altana

As a fully integrated component of a large multi-practice law firm, the IP group at Altana provides comprehensive commercial advice through close communication with other departments. Its agile, client-oriented team, comprised of 12 creative specialists, offers innovative solutions to contentious and transactional quandaries, collaborating with a network of patent attorneys to ensure the best technical support. The pace setter is Spanish speaker Frank Valentin, who handles litigation in the IT and life sciences sectors. In addition to his IP expertise, he has keen insight in the related areas of cybersecurity and data privacy.

Amar Goussu Staub

Whether clients are seeking strong representation in patent litigation, astute strategic advice or some combination of the two, Amar Goussu Staub is always a smart choice. The firm moves in virtually every industry and demonstrates particular dexterity when it comes to FRAND matters – a real advantage for its telecommunications clients. One leading FRAND expert is kingpin Cyrille Amar, whom competitors are quick to celebrate. He brings invaluable in-house experience to the table, gained from nine years working in the mobile telephony division of the Philips group. Colleague Jean-François Guillot holds the distinction of being a member of both the Paris and New York bars, and spends his time engaging in complex patent disputes and advising clients on licences and technology transfer agreements.

Armengaud Guerlain

Collaboration is the watchword at Armengaud Guerlain, a firm whose meticulous approach has helped it to forge and sustain myriad fruitful client relationships for more than half a century. Its laser focus on teamwork ensures that a fully briefed lawyer is always on hand to assist with all issues relating to a client’s portfolio or case, no matter when they might arise. Garnering wide acclaim is globetrotting polyglot Catherine Mateu, who has a knack for finding cost-effective solutions to patent infringement and licensing problems. “She is very efficient, very knowledgeable, has sound judgement and is easy to cooperate with. She is also very pleasant as a person and – importantly – she can be safely relied on to keep track of ongoing matters.” Founder Stéphane Guerlain is another influential presence, having been a member of the Paris Bar for more than 30 years. He has a fine-grained understanding of unfair competition law and extensive experience of managing patent disputes and offering strategic advice to French and multinational clients.

August Debouzy

A standout independent outfit on the French market, August Debouzy demonstrates exceptional capability when prosecuting patents, bringing contentious matters to a successful close and dispensing strategic advice. This versatility is reflected in positions on all three tables in the rankings. Despite its relatively small size, it makes light work of multinational proceedings, earning it the loyalty of industry titans such as Teva, Orange and Total. One enthusiastic client declares: “In short, there is no better patent attorney or patent law firm in the whole of Europe than them. I learned that I needed August Debouzy on my side.  I definitely did not want them to be on the other side of the table.” François Pochart and Grégoire Desrousseaux are the dynamic duo at the heart of the practice. Pochart’s guidance on regulatory issues, supplementary protection certificates (SPCs) and plant protection products is always on point; while Desrousseaux benefits from qualifications in both law and engineering. “There is no doubt of Grégoire’s extraordinary intelligence. However, what makes him truly stand out without equal is his fierce application of that intelligence and subject-matter expertise to achieving clients’ business objectives. He does not hesitate to take measured risks in the pursuit of total victory.” “He is a brilliant professional, able to handle a huge amount of data in a very short period of time and to extract its essence.”

BARDEHLE PAGENBERG SELAS 

A stalwart of the legal scene in neighbouring Germany, BARDEHLE PAGENBERG continues to impress with the output of its Paris office. The practice has carved a niche on matters involving non-practising entities, attracting warm acclaim from competitors in the process. A key figure is Julien Fréneaux, who relishes the ins and outs of multinational patent disputes in fields as varied as medical devices, sports equipment and mechanical engineering. He is also no stranger to licensing matters, technology transfer agreements and IP-related contracts, and conducts IP due diligence as part of large M&A transactions. At his side is patent attorney and attorney at law Dominique Dupuis-Latour, who combines patent prosecution with involvement in patent infringement and nullity proceedings before the courts, as well as opposition and appeal proceedings before the EPO.

Bird & Bird AARPI

The French arm of worldwide leader Bird & Bird marries local know-how with the resources and network of a sprawling international firm. Home to 22 dedicated IP practitioners, the practice coordinates must-win patent litigation for clients across the full spectrum of industries, most prominently life sciences and telecommunications. Life sciences maven Yves Bizollon recently represented Amgen in a fraught pan-European battle against fellow behemoth Fresenius. Bizollon is widely respected and has had a hand in numerous precedential cases, including two of significance for the European Central Bank and another which gave rise to a major breakthrough regarding the patentability of pharmaceutical drugs. Not least thanks to this stellar record, he is now a professor at the Centre for International Intellectual Property Studies (CEIPI) in Strasbourg. His trusted partner is Anne-Charlotte Le Bihan, who shines in pan-European patent litigation in the pharmaceuticals, electronics and telecommunications sectors. As adept at parsing complex technical matters as at addressing sensitive legal issues, she was elected president of the Licensing Executives Society France – a position that bears testament to her multitudinous talents.

Cabinet Beau de Loménie

Cabinet Beau de Loménie is held in high regard for the sterling prosecution work carried out by its 50-plus patent professionals from four offices across France, supported by an additional three in Germany and the UK. The outfit plays well in industries as varied as pharmaceuticals, mechanical engineering and IT, handling everything from original drafting to representation in proceedings before all of Europe’s main IP offices. At the centre of the practice are managing partners Philippe Hubert and Didier Intes: the former has keen chemistry and life sciences acumen, while the latter heads up the mechanics department. Fellow leading light Pierre Balesta primarily works within the aeronautic, civil engineering and physics fields. He is academically qualified in both law and general engineering, and is involved in litigation while also conducting due diligence reviews of patent portfolios.

CASALONGA

With both patent attorneys and attorneys at law among its ranks, CASALONGA provides a fully integrated service to multinational corporations, small and medium-sized enterprises and individual inventors alike, whatever their requirements. Its collaborative approach is particularly advantageous on cross-border litigation, as the firm can draw on the technical knowledge and legal skills of its practitioners to achieve the best possible results. Abundant scientific prowess emanates from patent attorneys Gérard Dossmann and Francis Zapalowicz, who excel in the life sciences and electronics, respectively. Dossmann has been with the firm for more than 45 years and lends a seasoned eye to contract negotiations and licence agreements, alongside his regular work prosecuting patents and coordinating litigation across Europe. Zapalowicz is likewise engaged on both prosecution and contentious mandates; semiconductors and integrated circuits are a forte. Working in close collaboration with this esteemed duo is attorney at law Arnaud Casalonga, who knows his way around an SPC and has litigated in areas as varied as mechanics, pharmaceutical goods and electronics; he also maintains a thriving competition law practice.

Cousin & Associés

While Pierre Cousin retired from practice last year, his impact can still be felt at Cousin & Associés, which – despite the absence of its founder – remains a potent force on the market, effortlessly conducting must-win patent suits across France and the wider continent. Agility and flexibility are crucial to the firm’s success: it puts together tailored teams and develops made-to-measure approaches to each issue that clients face, ensuring that every possible strategic option is considered. Laying down the line is Sandrine Bouvier-Ravon, who “displays the highest possible level of professionalism”. In the 10 years she has spent at Cousin & Associés, she has litigated countless patent disputes in a wide range of fields, from mechanics to chemistry.

De Gaulle Fleurance & Associés

Full-service outfit De Gaulle Fleurance & Associés provides A-to-Z patent assistance, managing litigation for companies with valuable patent portfolios while also helping them to optimise the commercial exploitation of those portfolios in the most tax-efficient way. A master of both arts is Julien Horn, a “sharply minded litigator” whose USP lies in architecting innovative mass litigation campaigns for IT and software companies. At his side is German speaker and media and technology expert Francine Le Péchon-Joubert. Like Horn, she has hammered out favourable results in all manner of disputes, while also maintaining a transactional practice encompassing R&D, licensing and M&A.

Dentons

As a vital cog in the wheel of the largest law firm on the planet, the French office of Dentons leverages the skills and experience of more than 600 IP lawyers worldwide to superb effect. The team displays superior levels of industry know-how, gleaned both from its own practitioners and from colleagues across the world, and ensures that cross-border litigation is always managed seamlessly. Heading the department in Paris, David Masson is well known for his life sciences work, but has also acted in several high-profile telecommunication suits. Also more than worthy of recognition is Isabelle Leroux, who coordinates IP litigation across France, Europe and the Middle East and advises on licensing, trade secrets and IP due diligence.

Duclos, Thorne, Mollet-Viéville & Associés

For more than half a century, Duclos, Thorne, Mollet-Viéville & Associés has had a prime seat in the French IP arena. It is unstintingly committed to understanding clients’ businesses, needs and goals, whether in the context of litigation or when consulting on IP strategy. Its motto is “Listen, analyse and be available” – an ethos embodied by Thierry Mollet-Viéville, hailed as “one of the top four patent litigators in France”. He has built this reputation over more than 50 years at the coalface and knows everything there is to know about all things pharmaceutical. At his side is Thomas Cuche, who is similarly capable in the pharmaceutical space and is “very easy to work both with and against”.

Germain & Maureau

Since 1849, Germain & Maureau has been filing and prosecuting patents across the full spectrum of technologies. This storied history is impressive, but its nine partners never rest on their laurels and continue to make Trojan efforts to ensure that patrons receive a first-rate service. Growth has been very much on the cards over the last year, thanks to the recruitment of 11 patent attorneys, including specialists in cutting-edge areas such as nanotechnology and artificial intelligence. The outfit has also established two new offices in Lausanne and Bordeaux, bolstering its offering even further.

GEVERS & ORES

GEVERS makes its sophomore outing in the IAM Patent 1000 rankings in 2020 – this year accompanied by ORES, with which the French practice has successfully merged. Its legion of patent attorneys based in three offices in Paris, Strasbourg and Toulouse file with alacrity at local venues and across Europe; new recruits have lately brought additional insight in areas such as software. Rainmaker Jean-Christophe Rolland deftly handles the heftiest of patent portfolios for multinationals and start-ups alike, dealing with everything from initial drafting to offensive and defensive oppositions. He makes it his mission to cultivate closer relationships between IP professionals and R&D and engineering teams.

Gide Loyrette Nouel AARPI

“Gide is a premium firm, both in terms of quality and in terms of the people.” It has all bases covered when it comes to patent litigation and transactional matters across a range of technologies; while its celebrated junior team climbs the ranks, senior partners Grégoire Triet and Arnaud Michel are still on hand to offer sage counsel. Triet is at home on local and international patent infringement and validity disputes, and recently played a crucial role in several cases involving SPCs. Telecommunications maestro Michel has the ear of clients across Europe thanks to his clear, creative approach. Snapping at their heels are Emmanuel Larere and Raphaëlle Dequiré-Portier, who each have almost 20 years’ experience of patent litigation, particularly in the life sciences. Larere is a soothsayer when it comes to the UPC, while Dequiré-Portier has a nuanced grasp of SPCs and the growing medical device sector.

Gowling WLG 

Though a relatively modest offering by size in comparison to some of its other worldwide offices, the French base of Gowling WLG repeatedly proves its might on knotty contentious and transactional briefs for first movers in the worlds of biotechnology, optical devices, telecommunications and blockchain. It considers itself akin to a boutique within a global law firm, leveraging international expertise while retaining flexibility and adapting to clients’ needs in real time. The commander-in-chief is Céline Bey, who has honed her understanding of French litigation procedure over almost two decades. Her broad legal know-how covers intellectual property, data protection and unfair competition; she is also a percipient counsellor on all aspects of non-contentious IP.

Hogan Lovells

Combining a strategic global outlook with deep local knowledge, the French patent practice at global giant Hogan Lovells puts in flawless performances for international blue-chips on critical cross-border disputes. Its six patent practitioners, housed inside a larger IP team comprising 22 fee-earners, excel in particular on life sciences matters, as evidenced by their work this year on a major infringement case on behalf of Eli Lilly. Taking charge on this case is Stanislas Roux-Vaillard, the Paris office patent chief. His calendar is stacked full of multi-jurisdictional litigation, most notably in the pharmaceuticals, telecommunications and chemistry fields. “He is very sharp and extremely good at arguing cases of complex technology in the court. It’s better to be with him than against him.”

HOYNG ROKH MONEGIER VERON AARPI 

HOYNG ROKH MONEGIER has long ranked among the crème de la crème of firms featured in the IAM Patent 1000. Having joined forces with Véron & Associés last year, it has further grown in stature: peers describe the merger as an “extremely interesting move which has reinforced an impressive position on the European market”. In this expanded incarnation, the firm continues to dispatch patent litigation and advisory work across all sectors with dexterity, supported by a pair of technically minded in-house patent attorneys. Overseeing this megalith is founding partner Denis Monégier du Sorbier, who is “extremely professional but also reactive and easy to hold discussions with”. The firm’s bench of highly capable and variously specialised litigators includes managing partner of the French group Sabine Agé and overall managing partner Benoît Strowel. Over more than 20 years, Agé has developed enviable expertise in cross-border litigation, with a particular emphasis on standard essential patents (SEPs) in the fields of multimedia systems and telecommunications. “Sabine is one of the absolute leaders in French patent litigation. She is very good and quite the fighter.” Strowel is equally well versed in cross-border litigation and qualified to practise not only in France, but also in Belgium and England and Wales. Technically adept, he is additionally armed with an MSc in general biochemistry and molecular biology from King’s College, London, which comes in very handy when representing major bio-pharmaceutical companies. In addition to this super-group of managing partners, two rising stars deserving of recognition are Florence Jacquand and Amandine Métier. Jacquand is a versatile practitioner with fluency in everything from chemistry and human and animal health to electronics; Métier’s remit is equally wide, although she has recently been particularly busy intervening in disputes concerning SEPs and FRAND licences.

Jones Day

The international reach of Jones Day is of immense value to its French contingent, which consistently delights patrons through a combination of bespoke, down-to-earth service and seamless collaboration with the firm’s worldwide network. In addition to intellectual property, practitioners in the Paris office have expertise across virtually all areas of business law, operating as a one-stop shop that can meet clients’ every commercial requirement. Its beating heart is Thomas Bouvet, an “effective litigator” who has spent more than two decades chalking up wins in cases involving patents, trade secrets and plant variety rights. His knowledge runs the gamut from SPCs to SEPs; and he also assists with the drafting of research, technology transfer and licence agreements. Heading up the office is fellow litigator Emmanuel Baud, who also focuses on cross-border technology transfer and licensing within the context of national and international transactions.

LAVOIX

With integrated teams of attorneys at law and patent attorneys working in harmony to provide a comprehensive patent offering across the innovation cycle, LAVOIX can meet and exceed the expectations of companies of all stripes and sizes. Offices in France, Germany, Italy and most recently Luxembourg give it pan-continental reach, making it a preferred choice for multinationals. CEO Philippe Blot was among the first European attorneys to obtain the ‘Patent Litigator’ qualification and is famed for his contentious and FRAND licensing activities on behalf of telecommunications companies. One client of 10 years’ standing asserts: “We appreciate his availability, his management capabilities and the quality of his advice, even in some tricky areas.” Managing partner for patents Gérard Myon runs the Lyon office, bringing priceless experience from a previous stint as an EPO examiner to the mix. Praised for his “deep analysis and solid advice”, Bertrand Domenego likewise knows his stuff when it comes to the EPO, having handled myriad opposition and appeal proceedings there.  He also devises IP strategies and conducts freedom-to-operate audits, as well as training future IP professionals at the CEIPI. Another regular at the EPO is the engaged and internationally minded Stéphanie Michiels, a trained chemical engineer who has also spent time working in the patent department of a multinational pharmaceutical company and then with major IP players in London.

Marks & Clerk France

Although it has since partnered with the formidable international Marks & Clerk network, Marks & Clerk France was initially established by the former leaders of a major electronics group. This unique heritage gives it the global reach and breadth of expertise of a multinational law firm, alongside local insight and a refined understanding of the electronics and telecommunications industries. Within these sectors, Marks & Clerk France has filed thousands of European patent applications over the last 10 years from its office in Arcueil, while simultaneously helping investors and start-ups to optimise their intellectual property. The already strong group of patent attorneys has benefited handsomely from the arrival of recent recruit Mark Bell, who boasts profound technical capabilities in software, networks and telecoms. He comes fresh from IBM, where he was senior IP strategist in the IP management solutions team – experience that informs his current work developing and implementing global IP strategies, advising on IP monetisation and licensing, and filing and prosecuting patent applications.

Pinsent Masons 

“The team at Pinsent Masons consists of top professionals, always mindful of their clients’ best interests. They are very detailed oriented, business focused and business savvy. All decisions are carefully considered, with in-depth discussions of the pros and cons.” From offices across Europe, Pinsent Masons deftly deals with cross-border matters that have an impact in several jurisdictions, while always keeping commercial goals in mind. The French office tackles everything from pre-litigation strategy and multi-jurisdictional validity and infringement disputes to the management of IP licensing schemes – all under the watchful eye of Emmanuel Gougé, a renowned lawyer with dual qualifications to practise in England and Wales and France. This litigator par excellence also has extensive transactional experience, including with FRAND licensing and patent pool issues. “We are fully satisfied by the quality, accuracy and efficiency of the work performed by Emmanuel,” enthuses one client. “He understands all the technical aspects of a case very quickly and is proactive in managing the case from a strategic perspective.”

Plasseraud IP

Plasseraud IP provides redoubtable, soup-to-nuts patent support, from pre-emptive actions to filing and prosecution; it also stands ready to jump in on infringement and validity actions and coordinate opposition and appeal hearings at the EPO should the situation so require. Its broad team of more than 50 patent attorneys displays technical ability across all sectors, including life sciences, chemistry, mechanics and electronics. With 10 offices across France, Spain, Germany, the Czech Republic and China, and the linguistic resources to draft in French, English and German, the firm is truly international in its outlook.

REGIMBEAU

REGIMBEAU maintains its status as one of the key patent attorney firms on the Paris scene.  Committed to staying on top of market developments, it has been generously sharing its wisdom with the wider community through its book Unitary Patent and Unified Patent Court – Europe Adopts New Tools to Promote Innovation and through the IP Academy it has established, European Patents and Designs: The Essentials. These extra-curricular activities complement its day-to-day representation of clients across a wide spectrum of industries, from life sciences to chemistry, information technology and mechanical engineering. A standout figure on the life sciences team is Frédérique Faivre Petit, who accrued in-depth knowledge of European legal systems stems as head of European patent litigation at a major pharmaceutical company. She handles all manner of contentious matters, from opposition and appeal proceedings to patent litigation.

Santarelli 

One of the elite patent prosecution outfits in the jurisdiction, Santarelli impresses for its strength in depth. With 25 patent practitioners on deck – seven of whom are partners – it has a broad technical wingspan; its attorneys can also handle contentious matters, which serves to enhance their prosecution and drafting skills. A varied roster of clients enjoy 24-hour access to their patent portfolios through an online customer portal developed and maintained in-house, which is personalised and updated in real time. Name partner Luc Santarelli has a glowing reputation consistent with that of his firm, cultivated over an illustrious career. In the words of one longstanding patron: “I have worked with him closely over the course of the last decade on numerous matters, principally advisory and contentious in nature. Luc is extremely knowledgeable in his field, responsive and a pleasure to work with”. His “talented team” includes Thierry Caen, a patent attorney who “not only has deep knowledge and interest in the life science field, but also shows great litigation sense”. The doctor of pharmacy is in charge of patent activities in the chemical, pharmaceutical and biotechnology domains. On the engineering side, the ace in the hole is François Lepelletier-Beaufond, who previously worked as a consultant in energy management for a government agency. He focuses on patent drafting and prosecution, as well as contentious matters.

Simmons & Simmons LLP

International law firm Simmons & Simmons has practitioners stationed in key patent litigation venues in Europe, including Paris. The addition of prosecution capabilities to its European offering two years ago has made it an even more attractive proposition, as it can now provide clients both in France and beyond with the full suite of IP services. The French office specialises in pharmaceuticals and leverages on the firm’s wider global network to devise future-proofed solutions on even the most demanding instructions. Two esteemed litigators within its walls are Marina Cousté and François Jonquères, who fluently speak the language of innovators in a dizzying array of technical sectors, including pharmaceuticals, chemistry and telecommunications. Jonquères also holds a PhD in pharmacy from the University of Montpellier and formerly worked at Sanofi Aventis Group, giving him a useful in-house perspective; Cousté comes highly recommended not only for her contentious acumen, but also for her experience in mediation and arbitration.

TALIENS

With offices in Munich and Paris, and a close partnership with BAYLOS in Madrid, IP boutique TALIENS has the whole continent covered when it comes to providing sound and pragmatic legal support alongside strategic advice across the gamut of patent-heavy industries. The firm frequently assists clients with patent enforcement and participates in thorny patent litigation, but is perhaps best known for its transactional prowess, drafting and brokering all manner of lucrative IP deals. A wizard in this area is co-founder Jean-Frédéric Gaultier, whose nuanced understanding of intellectual property is matched by an equally solid grip of the ins and outs of unfair competition law. He has won the loyalty of numerous high-profile innovators in the fields of telecommunications, pharmaceuticals, medical devices and mechanics.

Other recommended experts

Michel Abello of the eponymous abello is a former patent attorney who turned his hand to practising law in 2003; since then, he has put his combination of “great technical and judicial expertise” to good use on behalf of clients in the engineering and software industries. At HBC Avocats, Jonathan Burnham is on hand to offer support to life sciences players, assisting them with the preparation and negotiation of agreements. Having worked in law firms and in-house in France, England and the United States, he has a cosmopolitan outlook. Celebrated patent litigator Emmanuel de Marcellus has also participated in many patent portfolio audits as part of corporate collaborations, especially in the life sciences. He operates out of Cabinet de Marcellus & Disser. At Linklaters, Pauline Debré deftly handles high-stakes cross-border patent litigation in the healthcare and telecommunications sectors. “Pauline is really responsive and clear, with a perfect knowledge of the subject, but also the ability to be pragmatic and keep the commercial aims in mind. Her advice is always rock-solid. She provides useful and reliable recommendations that help when making business decisions. She thinks matters through to the end and crystallises her proposal for the first move to get to the end goal.” Chief of patents at Ernest Gutmann - Yves Plasseraud, Anne Desaix represents French and international research laboratories and dynamic start-ups, primarily in the life sciences. She makes light work of complex proceedings before the EPO and the French courts, and regularly conducts patent portfolio assessment audits at times of major corporate change. Bandpay & Greuter’s Renaud Fulconis has appeared in upwards of 100 oral proceedings at the EPO and has impressive technical chops, having spent three years at the Curie Insitute working on his PhD thesis at the interface between physics and biology. Business lawyer Antoine Gautier-Sauvagnac of FTPA Avocats is a seasoned coordinator of multi-jurisdictional litigation with an affinity for the fine print of licensing agreements. Bertrand Liard heads up the French IP practice at White & Case; he supplements his cross-sector, cross-border patent litigation acumen with an encyclopaedic understanding of IT regulatory matters. Stefan Naumann of Hughes Hubbard & Reed is admitted to both the French and Californian bars and has recently found a niche working at the crossroads between his two specialisms: IP and entertainment law. Marianne Schaffner has flown in from Dentons to build up the IP practice at Reed Smith in Paris. She is particularly active in the telecommunications and pharmaceutical spaces, where she collaborates closely with her US colleagues. The titular Denis Schertenleib of Schertenleib Avocats is a man of many talents, armed with a PhD in molecular neurobiology along with qualifications to practise at the Paris bar and as a solicitor in England and Wales. His workload centres on international litigation – predominantly in the life sciences, but also in chemistry, mechanics, telecommunications and physics. Having notched up over 35 years at the patent coalface, Dariusz Szleper combines IP and unfair competition law expertise, litigating from his base at self-titled SZLEPER | HENRY Avocats. François Tanty is a specialist in mechanics, physics and electronics, and has been a partner at Nony & Partners for 20 years. He shares his knowledge by teaching at the Chamber of Commerce and Industry of PARIS.
