Adam Acosta is a partner in White & Case's Global Antitrust and Competition practice.  He focuses on antitrust litigation, government investigations, and related counseling.

Recognized by Legal 500 US as one of three "Rising Stars" nationwide in the Antitrust Cartel category, Adam has helped clients achieve significant victories at virtually all stages of complex antitrust litigation.  Some of those major victories include:

  • obtaining dismissal of all federal and state antitrust claims in a product-tying case (Tim Hortons);
  • obtaining dismissal of all antitrust and False Claims Act claims in a sham-litigation case (Zytiga);
  • defeating a motion for class certification in a reverse-payment case (AndroGel);
  • prevailing at summary judgment in a product-hopping case (Doryx);
  • securing a complete defense verdict as part of the trial team in a price-fixing case (Toshiba).

In the pre-litigation context, Adam has successfully resolved numerous government investigations before the DOJ’s Antitrust Division, the Federal Trade Commission, and various state attorneys general, all without those agencies seeking injunctive, monetary, or other relief. 

Adam also routinely works with clients on compliance and competition-related counseling involving competitor collaborations, competitive intelligence, trade associations, information exchanges, and various business initiatives.

As immediate past President of the Hispanic Bar Association of the District of Columbia (HBA-DC), Adam led one of the largest and most active bar associations in the Washington, DC area. He has served as a board member for HBA-DC since 2015 and is active in the American Bar Association's Antitrust Section.

Before joining White & Case, Adam completed a two-year clerkship in the US District Court for the Southern District of Indiana.

  • Successful representation of entertainment/hospitality client in a post-merger conduct investigation by the DOJ's Antitrust Division and a state attorney general. The agencies did not take any legal action or seek any relief from the client.

Pharmaceutical Antitrust Litigation

  • Successful defense of Boston Scientific's subsidiary BTG International Ltd. against "sham litigation" claims related to patent litigation for Zytiga®. The district court dismissed all antitrust claims by direct and indirect-purchaser plaintiffs as well as a Qui Tam plaintiff under the False Claims Act. BTG was the only defendant dismissed in all three cases.
  • Successful opposition to direct-purchaser plaintiffs' motion for class certification in the AndroGel® "reverse payment" litigation in which the plaintiffs sought several billion dollars in alleged class damages.
  • Successful defense of Warner Chilcott against "product hopping" claims in the Doryx® antitrust litigation, securing the first ever grant of summary judgment against such claims. The Third Circuit affirmed on appeal.
  • Successful defense of Par Pharmaceutical and Paddock Laboratories in the seminal FTC v. Actavis litigation concerning "reverse payment" claims. After the US Supreme Court's decision in FTC v. Actavis, Inc., 570 U.S. 136 (2013) and follow-on litigation in federal district court, the FTC voluntarily dismissed its claims with prejudice for zero damages, no liability, and no injunctive relief beyond that already agreed to previously by the client's corporate parent in an unrelated matter.
  • Successful defense of Par Pharmaceutical and Paddock Laboratories in the In re AndroGel Antitrust Litigation, obtaining a voluntary dismissal with prejudice of all indirect-purchaser class-action claims with zero damages, no liability, and no injunctive relief.
  • Successful defense of Allergan related to alleged reverse payment and product hopping claims in the Asacol® antitrust litigation. On the eve of opening arguments, the First Circuit stayed the trial and granted an interlocutory appeal, ultimately vacating a federal district court's certification of an indirect-purchaser class.
  • Successful defense of a pharmaceutical company, obtaining a complete dismissal of a direct-purchaser plaintiff's class-action complaint on statute-of-limitation grounds, despite allegations of fraudulent concealment.
