All members of chambers are frequently involved in matters relating to registered trade marks (including both United Kingdom trade marks and European Community trade marks) and passing off.

This typically involves proceedings in the High Court for infringement and validity of a registered trade mark under the Trade Marks Act 1994. As this Act is derived from a European Council Directive which seeks to harmonise trade mark law across the EU, such cases can and do result in references to the European Court of Justice. Other related aspects of European law, such as exhaustion of rights, also often arise in these contexts.

Barristers from chambers also conduct opposition and revocation proceedings before the Registrar of Trade Marks in the UK in relation to UK registered trade marks and at the Office for Harmonisation in the Internal Market (OHIM) in relation to community trade marks.
