fail to. For four decades he has been lawyer, adviser and friend to many prominent companies and
investors. Some consider him the most powerful person in Silicon Valley. Companies beg for his law firm
to represent them. The 65-year-old chairman of Wilson Sonsini Goodrich & Rosati (WSG&R) has suddenly
been thrust into the spotlight first, for counselling many of the technology firms now under scrutiny for
backdating stock options (and in some cases, serving on their boards); and more recently, as outside
counsel to Hewlett-Packard (HP), for initi fuel dispenser ally defending the board s dubious investigative practices.
WSG&R boasts 600 lawyers and represents around half of Silicon Valley s public companies, including
Apple, Sun Microsystems and Google. Last year it ranked first in private-equity and venture-capital deals,
with nearly twice as many as its closest rival. Over the past five years WSG&R has worked on over 1,000
mergers and acquisitions, collectively worth over $260 billion.
The recent troubles cast a shadow over WSG&R s reputation. Although Mr Sonsini is not accused of
wrongdoing himself, many of his firm s clients are on the ropes. Former executives at Brocade
Communications suffered crimi fuel dispenser nal charges in July. Mr Sonsini served on Brocade s board until last year
and his firm was its outside counsel. He also was on the boards of Pixar, Echelon, Lattice Semiconductor,
LSI Logic and Novell—all firms at which the issuing of stock options is being called into question.
WSG&R dismisses the idea that Mr Sonsini faced a conflict of interest by acting as both director and legal
adviser to so many firms and says he did not advise HP in its investigation of board members. Mr Sonsini
initially said it was “well done and within legal limits� It now seems it was neither.
