Paul is Senior Partner (IP Litigation) with over 35 years of experience in intellectual property matters. He has worked in both non-contentious and contentious matters relating to patents, covering a wide variety of technologies including complex chemical cases, electronics and mechanical patents.
On the contentious side, he handled the successful defence of Black & Decker in an action brought by Electrolux, the outcome of which led to the Patents Court guidelines on experiments and expert’s reports. He was also involved in the erythropoietin litigation (Kirin Amgen) and stent litigation (Boston Scientific).
Paul is particularly noted in trade mark matters (registered and unregistered), having successfully litigated the first case under the Trade Marks Act 1994 (Wagamama Ltd v City Centre Restaurants plc). More recently, he was involved in the latest extended passing off case: Fage v Chobani.
He is also known for his confidential information practice and handled the Dyson v Strutt litigation, relating to misuse of confidential information, and the same litigation on important issues of costs. He also led the successful team in the First Conference v Bracchi case, which included executing an interlocutory search and seizure order against the defendant.
On the non-contentious side, Paul’s skill and experience in analysing and solving strategic IP matters is called upon by many international clients. It ranges from trade mark problems and licensing strategies, to patent analysis and assessment. He has also been instrumental in the negotiation and preparation of international licensing arrangements for patents and trademarks, and has been involved in many non-contentious dealings including corporate support by way of due diligence relating to the sale of businesses and the licensing of the IP, preparation of multi-national licensing and cross-licensing arrangements (including co-existence agreements), and most notably the £2 billion sale to Du Pont of ICI’s film business. Paul has also overseen programmes for the registration of trademarks in many overseas jurisdictions. He also deals with the copyright and design right field, and has acted for a management buy-out team in relation to computer software and computer hardware.
Paul has lectured on both patents and trade marks, as well as confidential information. He is well-known domestically and internationally and has been invited to speak at international conferences as far afield as Bulgaria, Egypt, the UK and USA. He also teaches trade mark law on the Intellectual Property Diploma Course at the University of Oxford. He has written many articles over the years on both patents and trade mark issues.
