John has over 25 years' professional experience. He prosecutes patent applications in the optical, electronic and software fields, with particular expertise in semiconductor device manufacturing equipment and processes. John's clients range from large multinationals to smaller start-ups, including firms that have successfully progressed beyond the early stages to develop extensive foreign filing programmes. Clients appreciate John's pragmatic and cost-conscious approach to prosecution as well as his ability to effectively capture the essence of an invention in drafting applications.
John also handles litigation and enforcement matters, having conducted IPEC and Patents County Court proceedings and assisted in various Patents Court proceedings over the years.Many matters have been successfully resolved without recourse to litigation, sometimes making use of alternative dispute resolution methods such as mediation and IPO Opinions. John's approach is to take clear and decisive action early in correspondence to prevent a matter escalating to litigation.
His experience at the EPO Boards of Appeal covers both offensive and defensive oppositions as well as ex parte appeals on substantive grounds and formal matters such as restitutio in integrum. John also successfully handled, on behalf of the opponent, a reference to the Enlarged Board of Appeal (G0004/97) that established that it is legitimate to file an opposition in the name of a strawman. He is the primary contact at J A Kemp for UK and Community Registered Design matters.
John has extensive experience in recovering lapsed patents and applications, using restoration and restitutio procedures in the UK Intellectual Property Office (UK IPO), the EPO and elsewhere in Europe. The crucial factor in such proceedings is correct presentation of the evidence; viewed from the appropriate perspective an apparently hopeless case can become much more promising. He represented the proprietor in Ament's Patent  RPC 647 which overturned the UK IPO's practice that lack of funds could never be a ground for restoration of an inadvertently lapsed patent.
John is "recommended" in The Legal 500.
John joined J A Kemp in 1988 and became a partner in 1994.
