Professional Qualifications
European Patent Attorney
Chartered Patent Attorney

As a Chartered and European Patent Attorney and European Patent Litigator, Jim is able to represent clients in matters before the UK Intellectual Property Office (UKIPO), the European Patent Office (EPO) and the Unified Patent Court (UPC).

Academic Qualifications
B.Sc. Chemistry, University of York
Ph.D. Chemistry, University of York

Scientific Background
Jim’s Ph.D. was sponsored by ICI and involved the synthesis and characterisation of novel fluorine-containing engineering thermoplastics.

Jim joined Abel + Imray in 1997 and is based in the Bath Office. Before joining Abel + Imray, he spent 21 months as a Research Assistant at the University of Durham, where he prepared novel polyether electrolyte materials for Li-ion batteries. Following that, he worked for three years as a Senior Research Chemist for a global chemical manufacturer, focusing on natural polymers, and polymer synthesis, including solution, emulsion, and suspension polymerisation of acrylate polymers, as well as a range of industrial applications of water-borne polymers including paper making, construction, oilfield, water treatment, detergents, and cosmetics. Jim is a Member of the Royal Society of Chemistry.

Experience
Jim’s experience includes patent work for a range of clients including US corporations, multinationals, and university spin-outs. Drawing on a background in both academia and the chemical industry Jim works with inventors, managers, and in-house attorneys to draft and prosecute patent applications that protect innovation and align with our client’s commercial strategy.
