Dr Marcus Grosch is a German qualified attorney-at-law and Partner at Quinn Emanuel. Marcus focuses on IP litigation, with a particular emphasis on patent litigation. Marcus is one of the most experienced German patent litigators. His expertise in patent litigation concerns clients and patents of various industries (high-tech, medical devices, pharma-bio) involving the coordination of lawsuits in multiple jurisdictions. Marcus also has specific experience regarding the interface of patents and antitrust laws (e.g. patents essential to industry standards and FRAND-defences). Marcus has pleaded hundreds of cases, both in the German patent infringement courts (mainly Mannheim/Karlsruhe and Düsseldorf, at trial and appellate level) and in opposition proceedings at the EPO (including appeal proceedings) as well as before the German PTO (cancellation actions) and the German Patent Court (nullity actions).
Before joining Quinn Emanuel in 2010, he was a partner at Allen & Overy for three years and a partner in a leading German IP boutique for five years. Marcus is a lecturer in patent law at the Freiburg University and the Mannheim University. He earned his PhD from Mannheim University (summa cum laude) and his LL.M. from Yale University. He was a member of the German National Academic Foundation (Studienstiftung des Deutschen Volkes), Germany’s elite scholarship foundation. For several years, the leading German law directory JUVE has recognized Marcus as one of the leading individuals in the field of patent litigation. In 2006 and 2012, JUVE acknowledged Marcus as one of the top 40 German lawyers under 40 years of age.
