Tilman Müller-Stoy

Prof. Dr. jur.

Tilman Müller-Stoy is widely recognized as a leading German patent litigator. Having won the very first inter partes preliminary injunction based on the very first Unitary Patent for his clients 10x Genomics and Harvard, he already is one of the pioneers at the newly established European Unified Patent Court. With over 20 years of experience in IP, he has handled several hundreds of patent disputes (including entitlement proceedings) in courts and patent offices, with a focus on high-profile, multinational matters. He frequently takes on a coordinating role, acting as the European lead counsel, so clients benefit from his solid understanding of the laws and procedures of all relevant jurisdictions. His expertise spans numerous technologies and sectors, for instance telecommunications, IT, consumer electronics, automotive, medical devices, and life sciences. Trained as a commercial mediator, Tilman also assists his clients in IP-related ADR proceedings, including national and international mediation and arbitration.

Tilman is particularly sought after in SEP/FRAND matters, having in-depth knowledge of numerous standards and related industry practice including the underlying economics. He assists his clients not only in such litigation but also in avoiding or preparing for it – be it as lead negotiator be it as trusted advisor in the background. As one of just a few, he already has comprehensive experience in the areas of 5G, connected cars, and IoT.

A significant part of Tilman’s daily work relates to technology transfer including licensing, R & D agreements, and corresponding aspects of antitrust law. He has vast experience not only in defending against, but also creating, evaluating, and enforcing major licensing programs, including compulsory licensing proceedings in the pharmaceutical area. 

His clients are large multinational corporations primarily headquartered in the US, Asia, and Europe as well as highly innovative SMEs that are hidden champions in their fields.
