Douglas is one of the few silks to excel at both hard and soft IP. His recent cases in the Court of Appeal include Industrial Cleaning Equipment (Southampton) v intelligent Cleaning Holdings Co (trade mark: acquiescence, departure from retained EU law; new defence to passing off); Industrial Cleaning Equipment (Southampton) v intelligent Cleaning Holdings Co (trade mark: acquiescence, departure from retained EU law; new defence to passing off); Interdigital v Lenovo, (patent, 4G/LTE telecoms standard), Warner-Lambert v NHS Scotland and others (damages enquiry on cross-undertaking relating to second medical use patent), 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). His range of work at first instance is even broader: from mobile phone apps (PlanetArt v Photobox) and medical devices (Coloplast v Salts) to pharma patent cases such as Neurim v Teva (interim injunction where patent held valid and infringed in other litigation) and Boehringer Ingelheim v Teva (fifth most commonly prescribed drug on the NHS) to computer software (Alphasharp v ADG Capital Management, a financial trading strategy; Trappit v GBT Travel Services, a travel management tool), computer games (Blizzard v Bossland, copyright in “Overwatch” game; Bethesda v ABT, “Fallout” game, trade mark) to smart trainers (Puma v Nike, trade mark) to champagne and polo (Veuve Clicquot v Polistas, trade mark).
In Court Douglas understands which points appeal to judges and which don’t. 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 in January 2022 he presented 2 sessions on “Developments in Global Patent Law” to panellists from Singapore, Hong Kong, Australia, New Zealand, EUIPO, and WIPO as part of a seminar arranged by the Intellectual Property Office of Singapore.
He is the Editor of Terrell on the Law of Patents, soon to be published in its 20th edition as the leading practitioner text on UK patent law.
