Other key lawyers:

Franck Klein


The law firm is setting new standards for Germany in the fields of physics, electrical engineering and electronics as well as mechanical patent litigation.’

‘Four partners and several collaborators work proactively to provide a complete service, ranging from providing non-infringement or infringement arguments, successfully fighting for or against the validity of patents, knowing about and finding necessary evidence, proposing workarounds and usually to winning cases or suggesting useful solutions.’

‘Fritz Emmerling is very successful in coordinating international litigation.’

Fritz Emmerling is great at analyzing cases, discovering strengths and weaknesses and finding solutions for the client. He knows what kind of external support is required. His cooperation with litigators, but also with teams in other countries or in joint defense groups is moderate and convincing. I have yet to see a comparable German patent lawyer in litigation.’
