Tokyo-based litigation partner David Case has left Orrick, Herrington & Sutcliffe to start his own firm – the second Orrick partner to make such a move within the last two years.

Case left Orrick in March after six years as a partner in the Japanese capital and launched his own firm, Asia Pacific Law, which focuses on intellectual property, commercial transactions, venture capital investments and disputes in the U.S. and Asia. Case will relocate to the U.S. and will be based on the west coast, according to a LinkedIn profile.
