hen he was eight, Ken began spending weekends in his family’s neon sign factory watching the fusion of art and science. This was the genesis of Ken’s pursuit of a life melding left-brained and right-brained thinking. Ken’s quest has resulted in him being recognized as one of the most successful intellectual property litigation attorneys in the United States. In 2022, Patexia ranked Ken #90 out of 9,553 patent defense litigators in the nation in its Patent Litigation Intelligence Report, which analyzes actual case outcomes. And for the past two years, Super Lawyers has named Ken a Rising Star.

This recognition has flowed from victories Ken has achieved in district courts across the country, at the Federal Circuit, and at the Patent Office. Ken has briefed and argued winning dispositive motions and claim construction. He was instrumental in Fisch Sigler’s recent garnering of extraordinary mandamus relief at the Federal Circuit on behalf of client Juniper Networks. Ken has also participated in more than twenty post-grant proceedings, taken and defended dozens of depositions, and contributed to several winning jurisdictional and venue motions.

Ken’s history in IP litigation began even before he attended law school. After graduating from the University of California, Berkeley with a degree in applied mathematics, Ken jumped into the IP world with both feet, serving two years as a paralegal at Orrick, Herrington & Sutcliff in Palo Alto. His introduction to the field motivated Ken to become an attorney himself, earning a scholarship to attend the University of San Francisco School of Law.

Ken’s favorite equation is Euler’s identity: e + 1 = 0. Ken, and many other mathematicians, consider this to be the most artistically beautiful formula ever crafted.
