McDermotts snatches McMahon from Orricks

One of the leading intellectual property (IP) litigators in Silicon Valley is leaving Orrick Herrington & Sutcliffe to join Chicago firm McDermott Will & Emery.

Terry McMahon, who headed Orrick’s IP group, will chair McDermotts’ West Coast IP practice, covering Silicon Valley, Orange County and Los Angeles.

McMahon launched Orrick’s IP department in 1995 when he joined the firm, and is known throughout the Valley for his top litigation practice. One of his biggest cases included acting as lead counsel for Advanced Micro Devices in its long-running arbitration against Intel, and in its victory over Intel in the Federal Court jury trial concerning the use of Intel’s microcode.

Other high-tech clients include EMC Corporation, Logitech and Pacific Bell. McMahon is also known for his roles in “bet the company” cases against Hewlett Packard, Hyundai and Creative Laboratories, in which a small company brings a case against a multinational and where defeat will result in the closure of the small company.

McMahon will significantly improve McDermotts’ visibility in the practice area, spread over offices on the West Coast, Boston, Washington DC and London. Chairman Larry Gerber says: “The addition of Terry in Washington DC, Tony de Alcuaz in Silicon Valley and Fay Morriseau in Orange County gives us an extraordinary team of IP trial lawyers nationwide.”

Last year the firm’s London office took on the head of Hammond Suddards Edge’s IP practice Larry Cohen to lead its City IP group.

McMahon’s other big cases include being hired by Lucasfilm to protect against the internet distribution of Star Wars Episode 1: The Phantom Menace, and representing Microsoft to defeat an injunction that would have prevented the rollout of Windows 98.
