Partner, Patent Attorney Southampton
Profile of Cathrine McGowan

I’ve been with D Young & Co since 2001 and was made a partner in 2019. I enjoy being able to work in a diverse selection of technological fields and with experienced and dedicated colleagues.

I represent multinationals, SMEs and academic institutions in a number of areas. These include the preparation and prosecution of patent applications, opposition and appeal work before the European Patent Office, national and international assignment and licence recordal, and the preparation of opinions on the validity and infringement of patents and applications. My main areas of expertise are in the technical fields of physics, mechanics and electronics. I’m particularly experienced with cases involving optical fibres, medical devices and software, image processing, sensors, telecommunications and packaging.

Before joining the firm in 2001, I gained several years’ experience in a London-based private practice. There, I focused on patent, design and trademark work for a diverse range of clients.
