Jon Gowshall

Equity Partner

UK Chartered Patent Attorney
European Patent Attorney

My background is biochemistry, and so my primary technical fields are biotechnology, pharmaceuticals, medicine, food science and medical devices. I work in patents and have wide experience in this area, including UK litigation and freedom to operate opinions. My core area of expertise is law and practice at the EPO, where I have considerable experience, including opposition and appeal procedures.  I have been named as one of the top 1000 patent professionals in the world in the IAM Patent 1000, with particular acknowledgement of my abilities and experience in opposition.

I qualified as both a UK and European Patent Attorney in 1989, and became a partner in 1993. From 2010 to 2015 I was Managing Partner.  I spend several weeks a year in the office in Munich, in connection with my work before the EPO.

I am a member of the epi Council, and am part of the CIPA education committee and epi Professional Education Committee.

I am married with two adult daughters - so have plenty of practice of arguing my case in the face of overwhelming odds - and live in North London. We spend as much time as we can meeting and laughing with friends. I am an avid music fan and regular concert-goer - the more obscure the better. I am also no stranger to disappointment, being a life-long supporter of Watford FC.



"A smart and practical representative before the EPO who achieves remarkable successes for clients.  His abilities extend beyond patent prosecution to very skillful respresentation in opposition and other inter partes proceedings"
