Jérôme Kommer is a partner in Quinn Emanuel’s Munich and Mannheim offices. Jérôme’s expertise covers all aspects of complex patent litigation, including the coordination of international litigation efforts. He represents the firm’s clients both in 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, UMTS 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 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.).

Legal 500 ranked Jérôme in 2020 as a “core attorney” of the team. Managing IP’s IP Stars ranked him as a Rising Star (2018) and a Notable Practitioner (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 recommend his "good understanding of law and technology", and say that 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).
