Representative Experience

  • Prevailed in a $40 billion battle for corporate control of Viacom on behalf of controlling shareholder and Chairman Emeritus Sumner M. Redstone that was waged in the courts of Delaware, Massachusetts, and California. The cases ended in a settlement “which firmly put the future of the corporate empire under the control of Mr. Redstone and his daughter.” (See “Fight for Viacom Is Said to End with the Redstones in Control,” The New York Times)
  • Representing Zeltiq Aesthetics, a subsidiary of Allergan, in a putative class action lawsuit alleging false advertising related to the CoolSculpting System, Zeltiq’s cold-assisted lipolysis technology.
  • Obtained a low-five-figure settlement in a putative consumer class action litigation seeking over $85 million in damages. The suit alleged that Allergan’s leading skincare and cosmetics line violated the Food, Drug, and Cosmetic Act and that the product was being marketed in a way that violates state false advertising and unfair competition laws. The settlement came days before plaintiffs’ class certification brief was due after aggressive offensive discovery revealed facts damaging to plaintiffs’ case.
  • Representing Sorrento Therapeutics Inc., a leading provider of antibody therapeutics and cell therapy, in an action against various U.S. and multinational entities and individuals for breach of contract, theft of trade secrets, and related torts.
  • Obtained a low-six-figure settlement in a putative consumer class action against Electronic Arts alleging invasion of privacy based on use of address book data to “find friends” through video game applications on Apple iOS devices.
  • Secured a pre-suit settlement preventing publication of a “tell-all” book about a technology company and its founder written in violation of nondisclosure agreements.
  • Secured denial of a temporary restraining order seeking to enjoin SpaceX from hiring former Broadcom engineers.
