Senior Partner at ThomannFischer
Fabian Leimgruber is a senior partner and head of ThomannFischer’s IP prosecution and litigation team. He is a registered European and Swiss patent attorney and admitted lawyer before the Swiss Federal Patent Court. He has over 20 years’ experience helping leading international companies build up their IP portfolios and resolve their IP and technology-focused disputes before trial and appellate courts, domestic and international arbitration tribunals and the European Patent Office (EPO).
Dr Leimgruber holds an LLM and a JD, and a PhD in physics. His particular area of expertise is implementing and leading international and national patent infringement litigation and nullity actions, handling complex cases before all the Swiss and German courts and the EPO. He and his team have run several large cases involving patents and standards. He has a substantial track record in EPO opposition and appeal actions, and in national nullity and infringement proceedings. In particular, he was involved in several cases that led to key decisions of the EPO Board of Appeal relating the patentability of emerging technologies.
Besides his procedural work, Dr Leimgruber maintains a large patent prosecution portfolio for international and national clients. He has many years’ experience in various large law firms in Bern, Basel and Zurich, with a focus on mobile communication and information technology, emerging technologies, nanotechnology, business methods and software patenting – particularly in the emerging field of insurance and financial technology patenting, as well as simulation technology, big data and the Internet of Things.
Dr Leimgruber provides strategic advice and expertise (IP due diligence, tax-related matters) and represents clients in European and Swiss arbitration and Asia Pacific cases. His long-term experience in Singapore and Shanghai gives him a deep insight into the particularities of various Asian legal systems.
As an author and speaker, Dr Leimgruber has recently addressed topics such as reverse payment agreements, developments in software and business model patenting (Europe, the United States and Asia-Pacific), emerging technologies, artificial intelligence and antitrust issues.
