Carl-Philipp Clarenbach studied mechanical engineering at the Technical University of Karlsruhe (now KIT) and at the University of Massachusetts, Amherst (USA). He completed his diploma thesis in 2005 in cooperation with the Dr. Ing. h.c. F. Porsche AG.

Subsequently, he underwent training in the field of intellectual property law at the law firm “Gleiss Große Schrell und Partner mbB” and completed a part-time law degree (law for patent attorneys). During this time, he also completed an internship at the Mannheim District Court and worked at the German Patent and Trademark Office and the German Federal Patent Court.

After his admission as a German Patent Attorney and as a European Patent Attorney (2009), he deepened his education in the field of intellectual property law by further legal studies with a focus on European intellectual property law and obtained a Master of Laws (LL.M.) in 2012. In the same year he became partner of the firm that had trained him.

Carl-Philipp Clarenbach is authorized to represent clients before the German Patent and Trademark Office (DPMA), the European Patent Office (EPO), the EUIPO, the German Federal Patent Court (BPatG) as well as before the German Federal Supreme Court (BGH) regarding nullity proceedings and proceedings that concern the grant or withdrawal of a supplementary protection certificate or the grant of a compulsory license. In addition, he is entitled to represent in matters of plant variety protection before the Federal Plant Variety Office. In addition, he is also authorized to represent his clients before the (European) Unified Patent Court, which will start its work in June 2023 and will be responsible for the new European Unitary Patent.

Since the beginning of his training, Carl-Philipp Clarenbach has been entrusted with the drafting of IP applications, with patent grant, opposition and nullity proceedings (concerning patents and utility models), with the preparation of opinions on patent infringement and validity, and with freedom-to-operate analyses. In addition, he is familiar with the registration and enforcement of designs and trademarks. He advises and represents German and international, large and medium-sized companies as well as university and commercial research institutions and start-ups. Furthermore, he trains patent attorney candidates in his office and regularly gives lectures and talks.
