I have specialised in intellectual property law since commencing practice as a barrister in 1983. I have acted in numerous matters relating to all of the main types of intellectual property. These have included a number of significant cases such as 

Designers Guild v Russell Williams on the distinction between idea and expression in copyright

PLG v Ardon on the interpretation of patent claims

C&H v Klucznik on design right

the Jif Lemon case on visual branding

Clearsprings v Businesslinx on the ownership of copyright in bespoke software

Ball v Eden Project on the ownership of trademark rights

Lux v Pike & Faronwise on patentability and prior use

Parmenter v Malt House on invoking fresh prior art after trial

Potton v Yorkclose on accounting for unrealised profits

Entec v Abacus on the scope of copyright in sketches

BSkyB v Lyons on the protection of encrypted TV signals

Experience Hendrix v Hillman on performers' rights

I am frequently instructed in cases relating to the internet, including 

domain name disputes such as,,,,,,,,,,,,,, and many other cases 

recovery of domain names registered by dissolved companies, such as and

copyright claims such as v Fitch

database right claims for screen-scraping by price-comparison websites

complaints about misleading content or branding as in Localtel v Greatxcape and Worldonline v Iomart

I am a WIPO and Czech Arbitration Court panelist for domain name disputes under the UDRP and the EU regulations.

I studied electronics and biochemistry at London University and have handled cases in a variety of technical fields, including oriented polymer nets, polyurethane coatings, statins, software, vehicle components and farm machinery. I am also the joint author of a paper on acute glaucoma. Further details of my education are set out in my curriculum vitae.

I did a Masters Degree in European Law at Brussels University and I am particularly interested in European aspects of intellectual property law, including the application of competition and free trade rules in this area and the interpretation of harmonising legislation.

My experience as head of IP law at Coopers & Lybrand UK has also given me knowledge of tax, valuation and commercial issues relating to intellectual property.

I have contributed to a number of publications on intellectual property law, in particular on the interface between protection of IP and prohibitions of restraints on free trade and competition.  Please click here for details.
