I’m a dual-qualified Chartered Trade Mark Attorney and European Patent Attorney. That means that I clear, register and enforce many different types of interesting Intellectual Property (IP).


From big charity names to fashion designs. From cancer campaign logos to social media use. From financial business brands to surgical instrument inventions. The team and I advise charities, membership organisations and socially responsible businesses.

I specialise in managing large international trade mark and patent portfolios. (Five languages and a love of travel help, as does a degree in Chemical Engineering.) My colleagues and I regularly speak at IP seminars, primarily for non-profits which we have a real sector expertise in. I have over ten years’ experience in IP and a background of co-heading the London office of an international boutique IP law firm.

Past and present clients include: Cruelty Free International, F M Conway, Girl Guiding, Giorgio Armani group, De’Longhi, the organizing committees of the Paralympic Games, Battersea Dogs & Cats Home, DEC, Samaritans, Crimestoppers, Shelter, Sightsavers, The Eve Appeal, The Institute of Masters of Wine, FairFX, and many others.


  • Trade mark infringement settlement for a membership body

    A commercial entity was selling items branded with marks similar to our client’s, taking advantage of our client’s well-known reputation within the sector. We negotiated a favourable settlement agreement, thereby avoiding costly court proceedings.

  • IP audit and protection strategy for a well-known charity

    We conducted a full IP audit for a household-name charity. This encompassed reviewing the scope of its existing trade mark protection, website notices, brand pack and its many and varied licence agreements. As part of the resulting brand protection strategy we revised the wording of licences and notices, filed several new trade mark applications in the UK and abroad and put in place brand monitoring services.

  • Commercial and legal aspects of a financial service provider rebrand

    A financial services provider needed UK and international trade mark searches for a shortlist of six names for a major rebrand, all within a very tight timeframe. We advised on both the legal aspects and the commercial considerations, including names, logos, website colour palette, and domain names.
