Professional background

I advise clients on a wide range of intellectual property disputes. My experience includes trade marks, passing off, copyright and design rights.

I have worked on several High Court cases:

  • Successfully represented Google LLC in the High Court to defend claims of trade mark infringement and passing off in relation to Google's use of the name "YouTube Shorts" (Shorts International Limited v Google LLC [2024] EWHC 2738 (Ch))
  • Currently representing Getty Images in a claim for infringement of copyright and other rights against Stability AI in relation to their generative AI model (IL-2021-000007: Getty Images (US), INC. and others v Stability Al Ltd)
  • As a trainee I acted for Oh Polly Ltd to assist in bringing a claim against fast fashion retailer Shein for infringement of unregistered design rights, supplementary unregistered design rights, continuing unregistered Community designs and copyright (IL-2024-000091: Oh Polly Limited and Bo and Tee Limited v Roadget Business Pte. Ltd and others)

I also have experience advising clients on protecting their brand and trade mark portfolios.
