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 Helps Client Novozymes Win Patent Infringement Case

October 27, 2011

Biotechnology powerhouse Novozymes has repeatedly turned to David Tellekson for his expertise in enforcing patent rights. Novozymes celebrated its first trial win with Mr. Tellekson in 2006 in the District of Delaware, obtaining a judgment of willful infringement, followed by an award of double damages and attorneys’ fees, against Genencor. It was therefore not surprising that Novozymes again hired Mr. Tellekson and his Fenwick team to pursue Danisco, a subsidiary of DuPont, in a patent case involving genetically modified proteins. The Fenwick team filed suit against Danisco in the rocket docket of the Western District of Wisconsin in May 2010 and tried the case to a jury in October 2011. After returning a unanimous verdict of willful infringement and validity, the jury awarded Novozymes $18.2 million in damages

The Fenwick & West team was led by David Tellekson and Virginia DeMarchi, together with partner Brian Buckley and associates Melanie Mayer, Jeffrey Lasker, Ewa Davison, Michael Saunders, Jeffrey Ware and David Austin.
