Stuart Raynor

Partner, Patent Attorney

Stuart has over 15 years' professional experience and handles work across a wide variety of chemical subject matter.

Stuart has handled patent applications in a large number of countries and has also been involved in the prosecution of patent families where cases have been filed in a number of jurisdictions and where co-ordination of the prosecution strategy has been essential. However, a significant proportion of his current work involves the prosecution of cases before the European Patent Office (EPO). Stuart has extensive experience of EPO opposition and appeal proceedings and attends numerous hearings each year. He has, in particular, been responsible for handling complex multi-party proceedings and was also recently successful in gaining an award of costs against an Opponent.

He works on behalf of a wide range of clients which include academic institutions and startup companies right up to multinational conglomerates. His clients are mainly based in the UK, the USA and Japan.

Stuart's work focuses on areas which include petrochemicals and pharmaceuticals and he has significant expertise in handing cases which involve polymers. He also has a particular interest in catalysis having spent a year at the Royal Institution investigating ferrocenyl complexes heterogenised to materials which included MCM-41.

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