Thomas Dienwiebel focuses his practice on patent prosecution. He is a member of our European practice team.
Thomas has significant experience in prosecuting patents before the United States Patent and Trademark Office, as well as the European Patent Office, which allows him to provide his clients with detailed guidance for transatlantic patent portfolios. He is one of a few “dual qualified” practitioners, admitted to practice in patent matters before both the USPTO and the EPO.
Thomas’ technical background is in the field of electrical engineering with a focus on electronics, telecommunications, software, optics, and medical devices. His experience also comprises European trademark, licensing, and domain arbitration matters, as well as border control procedures in Europe.
In addition to patent prosecution, Thomas also represents clients in opposition and invalidity procedures before the European Patent Office, the German Federal Patent Court, and the German Supreme Court. He frequently argues cases at the EPO. Thomas also has significant experience in patent litigation in Germany, in particular before the District Court of Düsseldorf, Germany.
Thomas graduated in Electrical Engineering at the University of Dortmund in 2002 after having worked as a photonics engineer at Tsunami Optics, Inc., Mountain View, California. He started his training in the field of intellectual property law at a patent law firm in Witten, Germany in 2003. After having finished his training, Thomas became admitted as a patent attorney in Germany in 2007. Later, he worked as a partner in a patent law firm in Dortmund, Germany.
