Margaret Arnott


UK Trade Mark and Design Attorney

BA, CITMA, High Courts Litigation Certificate in Intellectual Property

Margaret has been a trade mark specialist in private practice since 1992. She is a registered UK and European trade mark and design attorney and a member of the Institute of Trade Mark Attorneys. Margaret has considerable experience in advising a broad range of clients, including multinational corporations, in the development, management, exploitation, protection and enforcement of their trade mark portfolios. She is consistently recommended in The Legal 500 and has been commended for her “hands-on role” in managing trade mark work, and heading up a “well organised, reliable and responsive” team (2021). She has also been praised for possessing the “rare qualities of reasonableness and level-headedness as a litigator”, and described as “hardworking, sound, and has common sense and good presentation skills”. Margaret has been consistently ranked in the WTR 1000, a directory of the world’s leading trade mark professionals, where she is noted for being a “a trade mark encyclopaedia”, as well as someone who is “very pragmatic and will always provide the full picture prior to assisting in the decision making process.” She also features as a ‘Trade Mark Star’ in the latest edition of Managing IP’s IP STARS, a ranking Margaret has held consecutively for the last few years.

Margaret has over two decades of experience in trade mark protection and an impressive track record of representing a diverse range of clients, including multinational corporations, in the development, management and protection of their trade mark portfolios. In particular, Margaret has extensive experience of filing and prosecuting trade mark and design applications in many jurisdictions, and managing large portfolios of trade marks on behalf of her clients.  Margaret’s background as a commercial solicitor (non-practising), as well as her Higher Courts Litigation Certificate in Intellectual Property, is invaluable in her conduct of contentious intellectual property proceedings and in negotiating the settlement of such proceedings. Her role includes advising on brand name selection and clearance, trade mark prosecution and a full range of contentious work including oppositions, cancellation actions, domain name UDRP proceedings and litigation in court.  She routinely advises on the settlement of contentious proceedings and drafts any necessary co-existence/delimitation agreements. A member of the team that secured one of the first pan-European trade mark injunctions for infringement of a community trade mark (as it was then called), Margaret has successfully protected the interests of her clients in proceedings in the courts. She also provides regular intellectual property (IP) seminars and training for large multinational clients to help improve IP awareness amongst their marketing and legal teams.
