Philip specialises in patent matters in the fields of physics, electronics, mechanical engineering, and information technology. He has particular experience in automotive engineering, manufacturing, energy generation and storage, and sensor technology. In addition to drafting and prosecuting patent applications before the EPO and UKIPO, he also advises on the infringement and validity of UK and European patents and handles Registered Design matters. Philip also has experience in carrying out patent watches, freedom-to-operate searches, and European opposition work.
For over twelve years, Philip combined his role at Keltie with a long-term secondment to the patent department of a major UK automotive manufacturer. This enabled him to gain direct experience in the management of a large patent portfolio from an in-house perspective with a focus on securing effective patent protection across a range of different jurisdictions, particularly in the US, China and Japan. He also carried out numerous patent infringement investigations and co-ordinated assertion activities, including licensing negotiations and litigation support.
As a member of Keltie's IP Consulting Group, Philip draws on his in-house experience to advise clients on how best to maximise the quality of their IP rights in a cost-effective manner so as to create a commercially exploitable portfolio. He advises on patent landscape searching, the use of patent analytics tools for identifying monetization opportunities and pre- and post-grant reviews of patent families to strengthen and widen their scope of protection prior to assertion.
Philip graduated from the University of Sheffield in 2001 with an MPhys degree in Physics with Astronomy, during which his research project focused on organic light-emitting polymers and their application to flat panel display technology. Before joining Keltie in 2007 and becoming a Partner in 2018, Philip spent five years working at two other firms of patent and trade mark attorneys, during which time he obtained the Certificate in Intellectual Property Law from Queen Mary, University of London. He qualified as a Chartered Patent Attorney in 2009 and as a European Patent Attorney in 2010.
