Represented startup streaming service Quibi Holdings LLC in high-profile trade secret and patent litigation concerning Quibi’s app. Shortly before Quibi’s launch, we filed a declaratory judgment action for Quibi. Eko filed its own lawsuit the next day. In April 2020, we defeated a motion for preliminary injunction that sought to interrupt Quibi’s launch. Six months later, after Quibi announced it intended to return funds to investors, we defeated a second injunction request to interfere with Quibi’s wind down. The litigation resolved in September 2021 and was widely covered in the Wall Street Journal, Hollywood Reporter, and other publications.
