Rainmaker Yitai Hu is leaving Akin Gump Strauss Hauer & Feld, causing the firm to close its Taiwan office and take a closer look at its Silicon Valley office, firm Chairman R. Bruce McLean said Tuesday.

A patent litigator with big Taiwanese-based clients like RealTek Semiconductor Corp., Hu has kept both of those offices busy since he opened them for Akin Gump in 2005. The firm will now decide whether it makes sense to continue in Silicon Valley, said McLean.
