Wilson Sonsini

With 950 attorneys across 19 offices around the world, Wilson Sonsini Goodrich & Rosati is a global player with very deep tech roots. The firm has become a leader in technology and life sciences financings and M&A, tech licensing transactions, intellectual property, litigation, and regulatory and compliance matters..

Running Circles Around Everyone

Wilson Sonsini began as a simple three-man shop in Palo Alto under the name McCloskey, Wilson & Mosher. It was founded by John Wilson, Pete McCloskey, and Roger Mosher; McCloskey departed shortly thereafter in order to take a seat in Congress. Larry Sonsini became a name partner in 1973 after working at the firm for seven years. John Goodrich and Mario Rosati came on board in the early 1970s, and after Mosher’s departure, the firm took its current name of Wilson Sonsini Goodrich & Rosati.

One of the early hallmarks of the firm was its “Three Circles” business model, which focuses on representing enterprises through all stages of their growth. 

All About Tech

Wilson Sonsini focuses on five major practice areas—antitrust, corporate, IP, litigation, and regulatory and compliance—with a host of sub-practices. The firm’s technology experience has become as diverse as the industry itself. The firm now works with clients in the semiconductor, software, renewable energy, networking, media, fintech, social media, biotech, medical device, data storage and cloud, and consumer tech sectors. It also has a strong corporate finance practice that works closely with financial institutions, including Goldman Sachs and Morgan Stanley. Last but hardly least, the Wilson Sonsini venture capital practice has grown in tandem with early clients like Sequoia Capital, Mayfield, and Oak Investment Partners. To date, Wilson Sonsini has worked with thousands of companies and has helped raise billions of dollars. The firm has represented more than a hundred venture capital and private equity firms—many of which it helped create.

The firm boasts a strong IP practice—ranked among the top 10 in Vault’s Intellectual Property Practice Area Ranking. The patents and innovations team has over 140 attorneys, patent agents, and scientific advisors who work on everything from patent applications and patent prosecution to patent litigation and patent portfolio management to licensing and regulatory submissions and FDA-related submissions. Firm attorneys are also regulars before the Patent Trial and Appeal Board. Unique to the firm is its technology transactions practice, which focuses specifically on commercial transactions that are driven by intellectual property. Fifty of the firm’s lawyers focus exclusively on this practice. The group works with startups and tech clients across such industries as 3D printing, big data, biotech, digital media entertainment, e-commerce, fintech, health IT, open source, pharmaceuticals, renewable energy, and many more.

Ready to Launch

Corporate first and second years in the firm’s Bay Area offices can participate in Launch—a work allocation system for the corporate and securities practice. Associates in this program will receive a variety of assignments across the practice, rather than specializing in one specific area. A staff coordinator manages the workflow and provides regular feedback.
