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.
