Christopher Weber



My name is Christopher Weber. I am founding partner of Kather Augenstein and have specialised in patent litigation for more than 15 years. Before joining Kather Augenstein, I practised patent law for many years at a leading international law firm in Düsseldorf.

The focus of Christopher Weber’s work is in the field of technical intellectual property rights (patents and utility models). M experience ranges from the management of individual national proceedings to the coordination of international disputes concerning a wide variety of intellectual property rights. The proceedings conducted by me cover virtually the entire range of technologies, including the fields of software, electronics, pharmaceuticals, chemicals, mechanics, and plastics processing. I represent my clients in front of the civil courts and assist in legal validity proceedings before the European Patent Office, the Federal Patent Court and the Federal Court of Justice. In addition, I also provide advice for unfair competition litigation with a technical focus.

My assistant is Claire Edmonds.

The start of the Unified Patent Court is a big challenge for everyone, but we are perfectly prepared for you.

Christopher Weber, Partner

I am a member of the German Association for the Protection of Intellectual Property (GRUR) and the Licensing Executives Society (LES) and publish regularly in the fields of intellectual property and litigation law.
