Jérôme manages the firm’s Munich office. His expertise covers all aspects of complex technology litigation, including the coordination of international litigation efforts. He especially represents the firm’s clients in patent infringement and invalidity proceedings across a range of technologies, including telecommunications, IT, automotive engineering, medical products, and pharmaceuticals.

He has pleaded cases before the German patent infringement courts at district court and appellate level, in opposition proceedings at the EPO and in nullity actions before the German Patent Court and the Federal Supreme Court, involving, for example, network access technologies, speech coding, software interface architectures, and radiation therapy devices.

Jérôme has extensive experience in disputes involving FRAND licensing and standards, as well as the patentability of software. He regularly gives workshops on computer implemented inventions and teaches patent law at the University of Mannheim.

Jérôme holds degrees of the University of Heidelberg (JD equivalent) and the University of California, Berkeley School of Law (LL.M.).

Jérôme is ranked as notable practitioner and “up and coming” by Chambers in 2022, citing an impressed client: "Jérôme is extremely easy to work to. He is always available to talk and he also meets deadlines for specific deliverables. He speaks at the right level for in-house lawyers with both patent and non-patent backgrounds, which is exactly what we need." Legal 500 ranks Jérôme as a “core attorney” of the team. Managing IP’s IP Stars ranked him as a Rising Star (2018) and as a Notable Practitioner since 2020. Called a “young big-hitter” by Juve, Germany’s leading legal publication, Jérôme is recommended in Juve Patent in particular for his coordination of the joint defense group in the Daimler connected car cases. Clients call him a “super SEP litigator” (Juve 2021) and recommend his “good understanding of law and technology“. They also say he has an “excellent work ethic and produce[s] excellent results”, adding that he is “… always accessible, highly efficient and professional“ (Managing IP's IP Stars 2017).
