Overview

One of our strongest practice areas is patent litigation (infringement litigation / injunctions, invalidation trials / litigation for revoking JPO trial decisions, arbitration, customs import bans, etc.). In our intellectual property practice, through collaboration among lawyers and patent attorneys each specializing in a particular area, we have handled numerous cases involving a broad range of technological fields, including life sciences, materials, machinery, electrical equipment, electronic materials, communications, and business models. These include cases involving cutting-edge technologies such as biotechnology and telecommunications, as well as cases relating to standard essential patents. 

We also have extensive experience in litigation based on the Unfair Competition Prevention Act concerning trade secrets and counterfeit goods, design infringement litigation, trademark infringement litigation, and copyright infringement litigation.
