Philadephia-based Pepper Hamilton is opening a Silicon Valley office with three IP litigation partners taken from Goodwin Procter. Gregory Bishop, who had been the head of Goodwin’s California litigation practice, started Tuesday as the partner in charge of Pepper Hamilton’s new Redwood City office. He is joined by Thomas Fitzpatrick, who has been appointed co-chair of the firm’s intellectual property litigation practice, and IP litigator Andy Chan.

Opening an office in Silicon Valley has been on Pepper Hamilton’s agenda for about 18 months, part of a strategic plan to capitalize on its strengths in IP and white collar litigation and investigations, said firm CEO Scott Green. With “a number of really important clients” in the Bay Area, the 500-lawyer firm needed “boots on the ground,” he said.
