Leaders Directory

WIPR Leaders is a one-stop guide to the leading IP practitioners in the world. The handbook lists over 1,700 lawyers across patent, trademark, and copyright practices. Stemming from a four month nomination period in which we sought views from 12,000 IP professionals, our research team vetted every nominated lawyer 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.
