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 & West Awarded Prestigious First Tier Status from International Tax Review

March 4, 2010 (Mountain View, CA) – Fenwick & West LLP is pleased to announce that International Tax Review, a leading publication covering the tax industry, has named Fenwick & West in the first tier of the World's Leading Tax Transactional Firms for the United States, one of only five law firms in the entire U.S. to earn First Tier status. Fenwick & West has been ranked as a First Tier tax practice by International Tax Review since the survey's inception.

When commenting on how the advice attorneys give to their clients has changed over the past 12 months, David Forst, Chair of the Tax Group at Fenwick & West, said, "Changes in laws worldwide, increases in the complexity of laws and transactions and the proliferation of global revenue raising measures has put a premium on flexibility and creativity in providing client service."

"Fenwick & West advised on a broad array of significant recent M&A transactions in 2009, including, Blackrock's $13 billion acquisition of Barclays Global Investors, Cisco's pending $3 billion acquisition of Tandberg (Norway), EMC's $2.4 billion acquisition of Data Domain, and Autonomy Plc's acquisition of US-based Interwoven," says Jim Fuller, a partner in Fenwick & West's Silicon Valley office.

"The US tax rules, in terms of changes, have been more administrative than legislative, but cross-border M&A of course involves melding a foreign country's M&A rules with the US rules, in addition to anticipating changes in these rules," says Ron Schrotenboer, head of the M&A tax sub-group at Fenwick & West in Silicon Valley.

Fenwick's recognition was announced in International Tax Review's recent Global Tax Transactional Survey. The survey and related articles can be viewed in their entirety on the International Tax Review website (subscription required).
