Fieldfisher’s ‘exceptional’ IP team has recently been active in high-profile trade mark-related litigation and continues to act for well-known clients across the technology and gaming, retail and fashion, and manufacturing industries. Hastings Guise leads the practice, and he is sought after for his expertise in launching new brands, multi-jurisdictional clearance projects, and providing representation before the UKIPO and EPO in contentious proceedings. Claire Keepax is another key attorney in the team with substantial experience in global trade mark filing strategies. Leighton Cassidy relocated abroad in March 2024.
