Xiaoxi Tu is an associate in Weil’s Antitrust/Competition practice, where she focuses on civil litigation, including competitor and class action disputes, as well as antitrust counseling and government investigations.

Xiaoxi has experience at all phases of litigation, including motion practice, discovery, trial, and appeal. Some of her recent experience includes serving on Weil teams representing:

  • C&S Wholesale Grocers in the post-trial and appellate phases of a multi-hundred million dollar antitrust class action alleging that C&S and Supervalu entered into a conspiracy to allocate certain geographic markets in violation of the Sherman Act. In 2020, following oral argument, the Eighth Circuit affirmed the complete defense verdict Weil earlier won in 2018 dismissing all claims.
  • Hilton in a nationwide antitrust class action filed against Hilton and other major hotel chains, in which plaintiff alleges that that defendant hotel companies conspired to eliminate competition for branded keyword search advertising against each other, illegally raising consumers’ costs to find and book hotel rooms, and seeks damages and injunctive relief under the Sherman Act.
  • Hilton in a federal multidistrict antitrust class action challenging alleged agreements between online travel companies and hotels regarding the retail prices for online hotel room reservations.
  • Pilgrim’s Pride in a series of federal class actions across the country brought by direct and indirect purchasers alleging the major chicken producers reduced output to raise the price of broiler chickens.
  • An international electronics company in a DOJ antitrust investigation.
  • Nuance Communications and Bio-Rad Technologies as defendants in separate antitrust counterclaims related to patent infringement cases.

Prior to joining Weil, Xiaoxi worked at another international law firm, where she focused on litigating complex civil disputes.

Xiaoxi also has an active pro bono practice. Recently, she has been working as part of a Weil team, in collaboration with Sanctuary for Families, that successfully defended a mother and her children in proceedings commenced in New York federal court under the Hague Convention for International Child Abduction. In November 2019, the Eastern District of New York dismissed the petition against Weil’s clients.

Xiaoxi received her B.A. in Music from Wesleyan University, and her J.D. from University of California, Berkeley. During law school, she worked as a summer law clerk at the Office of the Solicitor in the U.S. Department of Labor.
