He handles a wide array of technologies including ceramics, glasses, polymers, composite materials, alloys, amorphous metals, electroceramics, magnetic materials, photovoltaic devices, energy storage devices, carbon, diamond, graphite, nanomaterials, chemical engineering processes, pharmaceuticals, biotechnology, synthetic organisms, and medical devices such as implantable MEMS devices, adaptive prostheses, sutures and surgical tools. Jim has been an inventor in fields ranging from lithium ion battery electrodes, inorganic fiber compositions, fuel cell components, graphite technology and collectors for current transfer to electrical vehicles.

As a former examiner for the European qualifying examinations for patent attorneys, and as a long-standing member of the Standing Advisory Committee before the European Patent Office (SACEPO), Jim is well versed in all aspects of European Patent Office law and practice.

Jim is a contributor to CIPA Journal and other professional publications, and has been invited to speak to various bodies including, among others, the American Intellectual Property Law Association (AIPLA) and the All China Patent Attorneys Association (ACPAA).
