Former Bingham McCutchen IP and litigation expert Tony Chen has joined the Los Angeles office of Sheppard Mullin as a partner in the firm's IP practice group. Chen, who specializes in complex IP litigation, represents both US and international clients, but with a particular focus on companies founded by Chinese-Americans. Chen plans to split his time between Los Angeles and Shanghai.

It's the fourth boost for Sheppard Mullin's IP practice in recent times with the firm snaring 
patent litigator Joy Arnold, trademarks expert Hal Milstein  and  biotech clinical contracting head Blaine Templeman in preceding months.  All three partners were previously with Heller Ehrman.
