Bryan C. Diner


Bryan Diner practices all aspects of intellectual property law, including strategic patent portfolio management, litigation, prosecution, opinion preparation, due diligence investigations, and interferences. His litigation practice has involved diverse technical areas, ranging from protecting the rights of innovative pharmaceutical companies in Abbreviated New Drug Application (ANDA) litigations to defending clients' right to use certain medical devices. He also has extensive experience in conducting IP due diligence investigations for all types of transactions.

Mr. Diner served as the managing partner of the firm's Brussels office from 1998 through 2003. During his tenure in Brussels, he learned much about the European legal system, from the European Patent Convention (EPC) to the diversity of laws and practice among the European national systems. Strategic portfolio management and litigation counseling for European clients is also an important part of Mr. Diner's practice. His knowledge of the European legal system and how it differs from that in the United States allows Mr. Diner to counsel both European and domestic clients on a full range of IP issues and to find cohesive solutions tailored to the needs of companies with global interests.

Mr. Diner lectures at various international programs and conferences targeted to the U.S. and European business community.
