Leaders Directory 2025

WIPR Leaders is a one-stop guide to the leading IP practitioners in the world. The handbook lists over 2000 lawyers across patent, trademark, and copyright practices. Following an extensive nomination period, our research team vetted the nominated lawyers for suitability by exploring their work. This meant looking at practice history, industry expertise and notable cases, as well as any additional activities, such as writing and teaching responsibilities, which have allowed the lawyers to shape and influence other and future IP practitioners.
