Wilson Sonsini Goodrich & Rosati is an American multinational law firm specializing in corporate, intellectual property, venture capital, and securities law for technology and life sciences companies worldwide. The firm serves clients ranging from entrepreneurial start-ups to multibillion-dollar global corporations, as well as venture capital firms, private equity establishments, and investment banks that finance them. Founded in 1961 in Palo Alto, California, as McCloskey, Wilson & Mosher by name partners Paul N. “Pete” McCloskey Jr., John Arnot Wilson, and Roger Laurence Mosher, the firm has maintained its headquarters in Palo Alto for over 60 years. It operates 18 offices globally, including locations in Austin, Boston, Brussels, Hong Kong, London, Los Angeles, New York, Palo Alto, San Diego, San Francisco, Seattle, Shanghai, Washington D.C., and Wilmington, DE. As a law firm, it does not raise venture funding or have a “latest round” in the traditional sense; instead, it provides legal services such as mergers and acquisitions, equity and debt offerings, and IP litigation. The firm does not publicly disclose current key executive names beyond its founding partners, though it employs a large roster of partners across its practice areas, including corporate and securities law specialists like Brian Appel in Palo Alto.
