In addition, he is advising on license agreements, research and development agreements, the law on employee inventions and issues relating to the protection of trade secrets. Based on his physics background and a corresponding in-depth understanding of complex technology he is holding a particular track record in litigating high-tech patents and patents on medical devices. He acts for his clients before the Unified Patent Court, national German courts, collaborates on opposition proceedings, and plans and coordinates multi-national litigation cases.
Klaus studied in Würzburg and Munich. He wrote his diploma thesis at the European Laboratory for Particle Physics, CERN, in Geneva. Parallel to his studies, he worked as a freelancer in a Munich based patent attorney firm for more than 10 years.
