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 >

Asyst Wins $75M Patent Verdict

February 02, 2007

Darryl Woo, chair of the patent litigation group at Fenwick & West, was recently quoted in an IP Law360 article entitled, "Asyst Wins $75M Patent Verdict." It highlights the fact that a federal jury in Northern District, California, awarded $74.4 million to Fenwick & West client, Asyst Technologies Inc., which accused rival Jenoptik AG of infringing their patent on its Smart Traveler system.

If issued a month earlier in 2006, the verdict would have been the fifth largest patent verdict of that year, according to Fenwick & West.

"I'm very pleased with the result," said Fenwick & West attorney Darryl Woo. "I think the company was very innovative at the time, and this basically validates the innovation."

The dispute between the two companies commenced 1996, when Asyst first sued Jenoptik for infringing two of its patents. The case bounced back and forth between the district court and the appeals court, with Asyst eventually voluntarily dismissing one of the patents in question.

Jenoptik claimed to have abandoned that type of technology in 1999, but the jury still held it liable for lost profits damages of over $30 million and price erosion damages of over $40 million.

The Asyst litigation team included: partners Darryl Woo and Michael Sacksteder and associates Joseph Belichick, Jeffrey Lasker, Mashhood Rassam, David Schumann and Karen Server.
