About

Provided by Fritz Lahrtz

Germany

Practice Areas

Fritz is a European and German Patent attorney. He represents his clients in all fields of intellectual property with an emphasis on patent prosecution and opposition, nullity and infringement proceedings. Specifically, in recent years, he has gained extensive experience in multinational infringement proceedings, where he represents his clients before the German Federal Patent Court, the German infringement courts as well as before the opposition divisions and appeal boards of the European Patent Office.

Since he is also responsible for establishing and coordinating the patent strategy of large patent portfolios, he has developed a deep insight into all aspects of patent prosecution. This includes also the provision of validity and infringement opinions.

His clients include start-up companies, universities as well as large multinational companies. Due to his scientific education in the fields of immunology and neurobiology, he primarily works in the technical fields of biotechnology, chemistry and pharma, with an emphasis on handling antibody-related cases.
