Catherine Cowley

Special Counsel

I love meeting clients, learning about their amazing inventions and then helping them to obtain the best protection possible to suit their commercial objectives.

Katie is a Chartered Patent Attorney and European Patent Attorney and is a special counsel and a member of the Patent Counseling & Prosecution practice group in Cooley's London office. She has many years of experience in dealing with patents and applications in the life sciences sector and in this time has handled most aspects of patent practice, including drafting and prosecuting patent applications before the WIPO, the EPO, the UKIPO and other national patent offices, patent infringement and validity, and freedom-to-operate. She also enjoys complex opposition and appeal work and frequently represents clients in oral proceedings at the EPO.
