Two Gibson Dunn Teams Recognized in Litigation Daily’s Litigator of the Week Runners-Up and Shout Outs

A Gibson, Dunn & Crutcher trial team led by partners Brian Rosenthal and Jaysen Chung and associate Nathaniel Scharn secured a defense verdict for Cisco Systems and Duo Security Inc. in patent litigation brought by CosmoKey. CosmoKey claimed the “Duo Push” feature in an early version of the Duo multifactor authentication system infringed its patent. But after a weeklong trial, federal jurors in Delaware found the Duo Push feature did not infringe CosmoKey’s patent, that Duo had used essentially the same system more than a year before the priority date of the asserted patent, and that the asserted claims were anticipated by Duo’s own prior art. The Gibson Dunn trial team included Yana Nebuchina, Erin Kim and Julian Manasse-Boetani, with local counsel Jennifer Ying and Travis Murray of Morris, Nichols, Arsht & Tunnell, and further assistance from Libby Moulton of Orrick, Herrington & Sutcliffe.

Shout-out to a separate Gibson Dunn team led by partners Trey Cox and Andrew LeGrand and of counsel Cristina Martinez Squiers, who helped GE Vernova beat back $400 million in damages claims from Alta Power, a power plant developer that planned to procure GE gas turbines through a refurbishment program offered by WattStock. U.S. District Judge Brantley Starr in Dallas sided with GE on summary judgment, finding that Alta’s master agreement with Wattstock barred consequential damages—including lost profits—between the parties and subcontractors such as GE. “While the underlying facts about how Alta came about and ultimately failed to get off the ground are interesting, those facts bear little relation to the court’s resolution of this dispute,” Starr wrote. “All one needs to know is that there is a contract that limits the parties’ liability and the court’s job here is to determine whether that contractual provision applies in this case.”
