Philip Harris

Call: 2014


Philip had 30 years’ experience as a registered trade mark attorney and solicitor-advocate in in-house and private practice (latterly as a partner and Head of Department in a prominent London IP attorney firm), representing major international clients, before transferring to the Bar in 2014. He specialises in all aspects of contentious and non-contentious trade mark law and has experience of copyright, designs and other “soft” IP rights too.

Philip’s contentious practice includes infringement and passing off in the English courts, especially the Intellectual Property Enterprise Court where he was the first Trade Mark Attorney to appear as trial advocate. He also specialises in proceedings before the UK Intellectual Property Office and the Office for Harmonization in the Internal Market.  As a former trade mark attorney Philip has extensive experience of working with international clients, especially those in the EU, US and the Far East, and he can continue to receive direct instructions for advice and assistance from overseas trade mark and IP lawyers.

A Fellow of the Institute of Trade Mark Attorneys, Philip was its President from 2006-2008 and is still a Council Member. He serves on several committees and was recently appointed Chair of the Education Committee. From 2009-2012 he was a Board Member of the Intellectual Property Regulation Board, having led much of the work leading to its creation as a regulatory body under the Legal Services Act 2007, which included giving evidence to a parliamentary committee.

In his free time Philip plays bass guitar, mandolin and banjo with a celtic-rock band which has   appeared at major venues and festivals across the UK and in Europe.
