Practice Areas

Douglas is one of the few silks to excel at both hard and soft IP.  His recent cases in the Court of Appeal include Icescape v Ice-World (patent: leading case on infringement under the doctrine of equivalents following the change in the law made by the Supreme Court in Actavis v Lilly); AP Racing v Alcon Components (patent), Frank v Nike (trade mark, upholding interim injunction granted in IPEC),  London Taxis v Metrocab (shape trade mark), Comic v Twentieth Century Fox (“Glee” trade mark).  Comic settled on the eve of the hearing in the Supreme Court in November 2017. His range of work at first instance is even broader: from pharma patent cases such as Warner-Lambert v Highland Health Board (second medical use) and Boehringer Ingelheim v Teva (fifth most commonly prescribed drug on the NHS) to telecommunications patents (Semafone v Eckoh, payment systems; BT v Assia, ADSL technology) to computer games (Blizzard v Bossland, copyright in “Overwatch” game; Bethesda v ABT, “Fallout” game, trade mark) to champagne and polo (Veuve Clicquot v Polistas, trade mark). His international experience includes numerous appearances in the European Patent Office (EPO), both Opposition Division and Technical Board of Appeal; and the Supreme Court of Bermuda (a trade mark case in 2017).

In Court Douglas understands which points appeal to judges and which don’t, so his clients always have an edge. He is a fighter when he needs to be and a first class cross-examiner.  Out of Court, he is a good team player with a sense of humour. He is highly rated for his inclusive style, and his willingness to educate and motivate the more junior people on the team.

Douglas is a Deputy High Court Judge, and mainly sits in the Intellectual Property Enterprise Court, or IPEC (appointed February 2015). He is also a Civil Recorder (appointed October 2010), where he sits mainly in the Central London County Court Chancery List; and a Crime Recorder on the South Eastern Circuit (appointed December 2014). He was a member of the Attorney General’s Panel of Junior Counsel to the Crown from 2010-2015 and acted for and/or advised many Government departments including the UK Intellectual Property Office (UKIPO), the Ministry of Justice, the Home Office, HMRC, the Treasury, and the Cabinet Office. He has acted as an expert witness on UK intellectual property law in US District Court proceedings in the Southern District of New York.  He is an in-demand speaker at major national and international IP conferences.  For instance at the UP & UPC Conference which was held at the EPO in Munich in July 2018 he presented a paper on the impact of Brexit on the UPC, and he also argued the mock trial which was held under UPC rules.   In August 2019 he presented a paper on infringement of second medical use patents to a global IP audience at Singapore IP Week as part of the judges’ panel, and he also presented a session on the IPEC.
