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 an experienced advocate. Margaret is consistently recommended in The Legal 500 and in previous editions 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 is recommended in the latest edition of WTR 1000, a directory of the world’s leading trademark professionals, in which she receives praise for her “profound knowledge of the trademarking process and the ability to lead negotiations effortlessly”, setting “a benchmark for the IP legal world that is difficult to beat”. She has also been noted for putting ‘the interests of her clients first at all times’ and providing ‘tailored advice and practical strategies that are very cost effective. She takes care of matters personally so you feel well-cared for at all times.’ Sources have commented that she handles ‘meaty trademark litigations very effectively – she remains strong for her clients, but is a respectful opponent who you can have a punchy conversation with’ and that she has ‘a keen eye for commercial resolutions’. Margaret features as a ‘Trade Mark Star’ in the latest edition of Managing IP’s IP STARS, a ranking she 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 IP seminars and training for large multinational clients to help improve IP awareness amongst their marketing and legal teams.

“Mathys & Squire have been key to the development of Xaar’s IP portfolio since the late 1980s and have supported us through a number of changes in business focus in an increasingly competitive space. The support and advice we receive from their dedicated team is well considered and takes into account the commercial imperatives of our business. We appreciate the quality of the legal and technical knowledge of the Mathys & Squire team, and their pragmatic and flexible approach.”


“Mathys & Squire are a highly professional organisation with the scale and breadth of capability we need to handle our global portfolio. I have found Margaret Arnott to be exceptionally diligent and good at her job. She has a good understanding not only of the trade mark areas which we work in, but also of deeply technical aspects of the technology, picking out the nuances and understanding where we fit in the marketplace.”
