Wilmer Cutler Pickering Hale and Dorr, which recently just picked up a veteran intellectual property litigator from Durie Tangri, has added three more partners to its Silicon Valley office.

Edwin Thom “Todd” Rumberger Jr., John Rockwell and Frederic Adam all joined the firm from Foley & Lardner, where they have worked closely together on transactional matters, Wilmer announced Thursday.
