US West Coast giant Wilson Sonsini Goodrich & Rosati has elected 12 new partners across the firm. Wilson Sonsini, which is a bellwether for the health of the West Coast’s technology-focused firms, promoted just seven last year. Chief executive John Roos said the promotions would be effective from 1 February 2006 and reflected the firm’s diversity. Of the 12 new partners, four are women. Six are in the firm’s corporate and securities practice, with one of those based in New York, while the others are in the firm’s Palo Alto headquarters.
