Overview

Our intellectual property practice covers not only IP litigation but also IP transactional matters, from the traditional IP transactions, such as licensing or research and development agreements to complex IP M&A, IP finance, IT related matters, or entertainment business.

To bring together the strength of a common focus, the Intellectual Property Practice Group (“IPPG”) consists of members who emphasize IP in their practices. Our IPPG gathers together some of the most well-regarded practitioners in Japan, and it exists to combine, for greater value, the diverse backgrounds and experiences of its members by sharing legal developments, strategy and market understanding relevant to our clients' most important concerns. By combining these diverse resources under the shared goal of providing the best IP legal representation to the best companies operating or based in Japan, we hope to exceed the expectations of every client on every matter in which we are called upon to assist.
