Goodwin Procter has continued to raid Cooley, most recently adding trial lawyer Patrick Gunn, a longtime Cooley partner and former head of its San Francisco office.

Gunn, who spent nearly 25 years at Cooley and who has represented high-profile tech clients over the years, moved to Goodwin’s San Francisco office, the firm confirmed Tuesday. The announcement comes about a week after Goodwin said it was adding five corporate partners from Cooley in Boston in its tech and life sciences practices.
