Fenwick & West was founded in 1972 in the heart of Silicon Valley—before “Silicon Valley” existed—by four visionary lawyers who left a top-tier New York law firm to pursue their shared belief that technology would revolutionize the business world and to pioneer the legal work for those technological innovations. In order to be most effective, they decided they needed to move to a location close to primary research and technology development. These four attorneys opened their first office in downtown Palo Alto, and Fenwick became one of the first technology law firms in the world.  MORE >

Why Life Sciences Companies Choose Fenwick

We Understand the Business and Science Behind Our Clients
Many of our practitioners have prior careers working in-house as researchers or executives, enabling them to predict and effectively respond to the nuances of the technical and legal issues that companies in this industry face.

We Are Proactive and Innovative– As Attorneys and Business Partners
As trusted legal advisors, we take on the responsibility of trying to predict what our clients will likely face in their future, and we advise our clients accordingly. Our attorneys are active in the business community, serving on committees of the SEC and some of the nation’s top research institutions. Within the legal industry, Fenwick spear-headed the move towards offering clients alternative fee arrangements, and the firm earned significant recognition in the media for its flat fee agreement with Cisco Systems, which was an emerging concept at the time. We understand the financial constraints new and established businesses face, which is why we offer a menu of alternative fee arrangements as well as initial client meetings, at no charge, to learn about the client’s history, technology and services, establish team roles, determine communication preferences and confirm reporting and billing requirements. We continue with ongoing meetings, at no charge, to ensure we are current with the client’s business strategy and goals and that we continue to meet management’s needs and expectations. We are proactive in bringing business opportunities to our clients that will enhance their profiles, whether it be through institutional funding recommendations, media outreach or award nominations.
