He joined the firm in 2014 as a French and European Patent Attorney, after five years of experience at a renowned IP firm. Admitted to the Paris Bar in 2016, he has since leveraged his dual scientific and legal background, practicing both as a European Patent Attorney (EPA) and as a lawyer. He is also registered as a UPC representative. He advises and assists French and international clients with all aspects of patent litigation, including enforcement and defense of their patent rights, before the French courts, the UPC, the EPO, and the French PTO (INPI), in both French and English. Lionel also continues to support his clients in preparing patent applications and handling examination processes before patent offices. A large proportion of his work involves mixed patent litigation cases pending before both the EPO and the French courts or the UPC, requiring a high level of interaction. His scientific background has naturally led him to handle cases in sectors such as telecommunications (including FRAND licensing disputes), energy, medical devices, and the automotive industry, almost systematically involving large corporations and representing international clients on a regular basis. Lionel contributes to the transmission of knowledge through teaching activities at leading engineering schools (Ponts Paristech; CentraleSupélec), law schools (Paris-Saclay University: Master 2 LEAD; Strasbourg University: CEIPI), and universities abroad (University of Michigan). > Lionel Martin is clearly a clever and very insightful lawyer, making waves in the UPC. He is very responsive and strong in communication. > > Chambers and Partners France 2025 ## Background - 2015 EFB Paris - École de Formation des Barreaux de Paris | Paris Bar School - 2013 Paris 2 - Université Panthéon Assas | Bar School Admission (CRFPA) - 2010 Paris 2 - Université Panthéon Assas | Master’s degree in Private Law - 2009 Université Robert-Schuman - Université Robert-Schuman | CEIPI (Patents) - 2008 ENPC - École des Ponts ParisTech | Engineering Degree, Mechanical Engineering and Materials Science ## *Rankings and* **Recognition** m - (01)Best Lawyers 2027 - France Technologies Media IP The Best Lawyers in France - (02)IAM 2026 - France Litigation Gold - (03)Chambers and Partners 2026 Intellectual Property Band 1 [More distinctions](https://www.august-debouzy.com/en/distinctions/?search_type-collaborateur%5B%5D=lionel-martin) ## *Latest* News k [13/02/26 Press release 1 min Classement Chambers and Partners | Global Guide 2026 Chambers Global 2026 distingue une nouvelle fois August Debouzy, avec 3 expertises classées et 10 distinctions individuelles, saluant l’excellence et l’engagement de nos équipes.](https://www.august-debouzy.com/en/press-release/classement-chambers-and-partners-global-guide-2026/) [05/02/26 Press release 3 min Chambers and Partners France Guide 2026 Rankings Chambers France 2026 distingue une nouvelle fois August Debouzy, avec 13 expertises classées et 25 avocats reconnus pour leur excellence et leur leadership.](https://www.august-debouzy.com/en/press-release/chambers-and-partners-france-guide-2026-rankings/) [15/05/25 Legal Article 17 min Clarity On Knotty Patent Jurisdiction Questions From CJEU Despite the emergence of the Unified Patent Court in 2023, with jurisdiction over 18 of the 27 European Union member states for both infringement and validity, the national patent courts in the EU retain a competitive jurisdiction.](https://www.august-debouzy.com/en/legal-article/clarity-on-knotty-patent-jurisdiction-questions-from-cjeu/) [21/03/25 Legal Article 1 min UPC – The interpretation of patent claims by the UPC Claim interpretation is central in patent infringement and revocation litigation.
