After a 10-year hunt, Sheppard, Mullin, Richter & Hampton is finally planting its flag in Silicon Valley, picking up the last two partners from Thelen Reid Brown Raysman & Steiner‘s tiny office there.

Along with Thelen’s Marc Sockol and Riaz Karamali, Sheppard Mullin also hired Karen Canaan, a former partner at Mintz, Levin, Cohn, Ferris, Glovsky and Popeo with her own life science patent boutique. The firm will round out the initial group by moving Sheppard partner James Chadwick from San Francisco.
