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 London Taxis v Metrocab (shape trade mark), Comic v Twentieth Century Fox (“Glee” trade mark), AP Racing v Alcon Components (patent, leading case on added matter), Phil & Ted Buggies (also patent). 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. Premonition, the independent legal performance database, analysed the performance of 1381 barristers across 1844 cases in the UK High Court, Chancery Division, for the period 2014-2016 and found that Douglas was one of only two QCs (and the only one in IP) with a minimum of four appearances to achieve a 100% success rate. Douglas not only maintained his 100% record for the High Court, Chancery Division in Premonition’s 2017 update, but he also added a further 100% record for his appearances in the Intellectual Property Enterprise Court. 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, eg Singapore IP Week 2016 and CITMA Spring Conference 2017.
