Antitrust / Competition

  • In re Vitamins Antitrust Litigation – Brian served as co-lead counsel in the landmark case on behalf of vitamin direct purchasers who were overcharged as a result of a ten-year global price-fixing and market allocation conspiracy. The case settled for over $1 billion, and in 2003 the case went to a jury trial resulting in a verdict of $148 million in trebled damages. The jury trial was the twelfth largest U.S. jury verdict that year.
  • Empagran, S.A. et al. v. F. Hoffmann-LaRoche, Ltd., et al. – Brian was one of the principal lawyers that led this case on behalf of foreign vitamin purchasers. The case was litigated all the way to the Supreme Court, resulting in a groundbreaking judgment on the scope of the U.S. Sherman Act jurisdiction. The case was designated as the “Matter of the Year” by The Global Competition Review.
