Richard specialises in all aspects of intellectual property law with a particular emphasis on patents.  His clients benefit from his unique background, first as an electrical engineer and later as a Chartered and European Patent Attorney. Richard is acknowledged as one of the leaders in his field.

Richard’s patent practice encompasses a diverse range of technologies. These include his specialist field of electronics in addition to mechanical engineering, chemical engineering together with some pharmaceutical and biochemical work. He has particular expertise in the telecommunications sector having advised such giants as Apple, LG Electronics, Nokia, Motorola and Symbian. Recently he has represented the UK Government in the Pregabalin litigation concerning second medical use claims.

His dual qualification as a European Patent Attorney has resulted in him appearing frequently before the European Patent Office. Notable successes include acting for Zipher in respect of patents which had been revoked by the UK courts.

He has particular expertise in cases involving patent and trade mark attorney practice both before the UK IPO and the EPO. This includes unusual and complex areas such as judicial review of IPO decisions made as an International Receiving Office, restitution and actions concerning attorney negligence.

Richard is equally at home with the other intellectual property rights and has carved a niche in designs and ‘difficult’ copyright cases.  He is one of the few counsel to have appeared before the CJEU (General Court) on a designs matter and one of the very few to have appeared before the UK Registered Designs Appeal Tribunal. He has been involved in a number of cases which have pushed the boundaries of what is protectable under the law of copyright and database rights.

In addition to his IP practice, Richard also advises on a multiplicity of IT matters, in particular in relation to contractual issues involving a technical aspect, the licensing of IP rights and software copyright.

Richard is one of the general editors of the Black Book (CIPA Guide to the Patents Acts). He lectures and tutors regularly on IPRs to patent and trade mark attorneys and solicitors. He is a visiting lecturer of CEIPI on the European patent litigation diploma.
