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 >

Fenwick Intellectual Property Advisor Colleen Chien Joins White House Office of Science and Technology Policy

Mountain View, CA (October 4, 2013) – Fenwick & West intellectual property scholar and former associate Colleen Chien has joined the White House Office of Science and Technology Policy as senior adviser to U.S. Chief Technology Officer Todd Park on intellectual property and innovation.

After graduating law school in 2002, Chien began her legal career as a patent prosecution associate at Fenwick & West where she helped Fenwick build patent portfolios for Fenwick clients like Symantec. Chien also provided intellectual property counsel on the Fenwick team that represented Macromedia in its landmark $3.4 billion merger with Adobe Systems.

As a professor at Santa Clara University School of Law, Chien focused her research on patent trolls – or patent assertion entities (PAEs), a term she coined and which is regularly used in scholarly circles – and her work on patent trolls, including recent papers “Startups and Patent Trolls” and “Patent Trolls by the Numbers,” helped spark the current national conversation. Based in large part on Chien’s research, the Obama Administration focused its plan to combat patent trolls – rolled out in June 2013 with five executive actions and seven legislative recommendations – on targeting the behavior of trolls rather than trying to define a patent troll, and the June White House ​proposal for reform repeatedly cites her research.

While working at Santa Clara Law, Chien remained a trusted advisor, working with Fenwick as an IP scholar up until her recent appointment. In this role, she stayed in close contact with Fenwick attorneys, giving regular in-house presentations related to her scholarly work and working with Fenwick attorneys to understand the real world implications of her work on the patent system and on patent practitioners.

The White House Office of Science and Technology Policy was established in 1976 to provide counsel to the president and other members of the Executive Branch on the effects of technology and science on domestic and international affairs. In her new role, Chien will advise U.S. CTO Todd Park on issues related to intellectual property and innovation, as well as privacy, open government and civil liberties.
