Dale Cendali is a ‘world class litigator’ who heads a ‘great team of highly trained lawyers’ at Kirkland & Ellis LLP. Alongside John O'Quinn, the ‘brilliant’ Claudia Ray and Diana Torres, Cendali recently represented Nike at the Federal Circuit, which overturned a previous ITC ruling, supporting the client’s enforcement efforts against knockoffs of its Converse Chuck Taylor design. Ray, Torres and Cendali also assisted Johanna Schmitt and Joshua Simmons in defeating a motion for preliminary injunction filed by Equinox Hotel Management against client Equinox Holdings; the plaintiff sought to prevent the client from using the ‘Equinox’ trademark in connection with its forthcoming hotel line, though failed to establish a likelihood of success on the merits of irreparable harm. Industries of expertise include media and entertainment, software and technology, financial services, consumer products and fashion. Torres is based in LA while O’Quinn operates from Washington DC. All other named attorneys are part of the firm’s New York office.
