Former Mayer Brown IP Partner Wang Goes In-House at Rohm Co.

Longtime Silicon Valley intellectual property lawyer David Wang has left Mayer Brown to become Rohm Co.'s top U.S.-based in-house IP counsel.

Wang started last month as chief counsel of legal and IP for Rohm, a Japan-based semiconductor and electronic parts manufacturing company.

He made the jump after working as a partner with Mayer Brown since 2016, in the firm’s Palo Alto, Calif. office. Before that, Wang was a partner with Winston & Strawn’s Silicon Valley office located in nearby Menlo Park.

Wang said the gig is “an exciting opportunity” to represent a former client in a different capacity, and to be able to handle a wider array of legal matters for the company.

Aside from overseeing IP, he said in his new role, he’d get to work on general litigation, antitrust, employment law, and tax matters.

Wang was reluctant to go into specifics about clients he represented and individual matters he handled while at Mayer Brown, though he did say that he mainly worked on patent litigation and patent licensing.

While at Winston & Strawn, Wang had gained extensive experience representing different Asian-based companies including those based in Japan, Taiwan and China, on U.S. patent litigation matters, according to a Mayer Brown statement at the time of his hiring there.

Wang has handled patent infringement matters before various courts and the International Trade Commission including Section 337 actions. He has represented clients that manufacture everything from electronics, digital and analog circuits, software, and semiconductor devices, to robotics and high-definition televisions.
