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 >

Dargaye Churnet

Associate, Litigation  

San Francisco 415.875.2460

Overview

Dargaye Churnet focuses his practice on patent litigation matters and patent post-grant proceedings, such as inter partes reviews (IPRs), for technology-based clients. He also has experience drafting and prosecuting patent applications at the U.S. Patent and Trademark Office. In his litigation practice, Dargaye has gained extensive experience drafting various motions, drafting invalidity and infringement contentions, working closely with technical experts to prepare declarations, managing discovery, taking depositions, and working on appeals.

Additionally, Dargaye has worked on every stage of the IPR process—from petition through oral hearing—in representing both petitioners and patent owners in several IPR proceedings, including drafting IPR petitions, preliminary responses, patent owner responses, and petitioner replies. Dargaye’s IPR experience includes representing a Fortune 500 company in two IPR proceedings in which the Fenwick team was able to successfully invalidate nearly every claim of the challenged patents.

Dargaye is also extremely active in pro bono. His pro bono work has included securing a favorable settlement for an inmate client who had accused prison guards of excessive force and failure to intervene, successfully representing a tenant in an unlawful detainer eviction case brought by the landlord, consulting low income inventors on patent prosecution matters, and aiding veterans in proceedings with the Navy Board. Dargaye served as the lead attorney in each of these matters.

Prior to joining Fenwick & West, Dargaye represented clients in patent litigation and prosecution matters at the Chicago office of a prominent intellectual property firm.

Before entering law school, Dargaye gained invaluable experience as a patent examiner at the U.S. Patent and Trademark Office. As a patent examiner, Dargaye spent three years analyzing patent applications and determining which should be granted a patent.

While in law school, Dargaye was Editor for the Northwestern’s Journal of Technology and Intellectual Property.
