Who’s Who Legal


Tim has a strong technical background that has enabled him to represent clients in some of the largest and most complex intellectual property disputes to come before the UK courts in recent years.

Tim specialises in multi-jurisdictional litigation, particularly in the patents field where he has experience in coordinating litigation taking place simultaneously across Europe, North America and beyond.

He is a solicitor advocate and has represented clients as an advocate in the UK and European Patent Offices, the English High Court, Court of Appeal, House of Lords and the European Court of Justice.

This breadth of expertise means that Tim often lectures on all aspects of IP law.
