Leaders Directory 2025

After a decade of growth, WIPR Leaders has undergone its most significant transformation to date. The 2025 edition marks the beginning of a more selective, research-driven era — shifting away from a volume-based listing to one that truly reflects the very best of the global IP legal profession. 

The WIPR research team spent months overhauling the methodology, curating a refined list of top-tier IP practitioners across 80 countries and six continents, each recognised for their proven track record, peer endorsements, and outstanding contributions to the field. With a new focus on quality over quantity, only standout lawyers were nominated by their firms. Each profile is enhanced with commentary from peers and clients—offering richer insights into their expertise and reputation. Whether clients are searching for trusted external counsel, global referral partners, or top-tier legal insights—WIPR Leaders 2025 is an essential resource. The directory spans specialists across copyright, design, patents, trademarks, and trade secrets, from global powerhouses to specialist boutiques. This first iteration of the 2025 directory also notates of contentious and non-contentious specialisms. 

The lawyers included this year represent the very best in IP law—trusted, flexible, and highly respected by peers around the world.
