Intellectual property: Patents

August Debouzy

With extensive and wide-reaching experience that includes complex patent infringement litigation before the UPC, IP offices, and French courts, the team at August Debouzy has a strong footing within the industry and also handles contractual and licensing matters, as well as patent applications. The firm is lauded by clients for its deep industry expertise, which is evidenced in co-head Grégoire Desrousseaux's previous experience as an engineer, bolstering his notable ability to handle complex litigation, including FRAND and oral hearings before The Hague and in Munich courts. Heading the department alongside Desrousseaux is François Pochart, who specialises in advising clients active in the healthcare, pharmaceuticals, life sciences, biotech, and chemical industries, and Lionel Martin, who specialises in aiding clients in the telecommunication, energy, medical devices, and automotive industries. Julia Cohen-Solal and Pierre-Olivier Ally are also key names at the firm. Abdelaziz Khatab left the firm in 2024 to join Simmons & Simmons.
