DLA Piper has forged ahead on its hiring spree in California, bringing on three partners in San Francisco in recent weeks.

The three additions are John Maselli, a former Amazon.com in-house lawyer who came to the firm from Goodwin Procter, Michael Sitzman, a longtime patent litigator at Gibson, Dunn & Crutcher, and Soumitra “Sam” Deka, a former intellectual property counsel at Arnold & Porter Kaye Scholer.
