Stuart Raynor

Partner, Patent Attorney

Stuart is a partner based in our London office. Stuart handles work across a wide variety of chemical subject matter, with a particular focus on polymers and catalysis. Stuart’s technical knowledge in these areas is extensive and is supported by a year spent at the Royal Institution investigating ferrocenyl complexes heterogenised to materials which included MCM-41.

Stuart has extensive experience of EPO opposition and appeal proceedings, particularly in the polymer and catalysis fields. He attends numerous hearings each year, and frequently handles complex multi-party opposition proceedings.

As well as handling contentious EPO opposition and appeal proceedings, a significant proportion of Stuart’s work involves the prosecution of patent applications before the European Patent Office. Much of this prosecution is for applicant companies based in Japan and Korea. Stuart regularly visits both countries.

Stuart joined J A Kemp in 2000 and became a partner in 2010.
