Matthew S. Weiler, who has over a dozen years of experience litigating complex matters in both federal and California state courts, focuses his practice on complex commercial litigation, including antitrust, consumer, and securities actions.

At BFA, Matthew primarily prosecutes antitrust actions, representing individuals, companies, and investors who have been harmed by fraud and unfair business practices.  Matthew is currently pursuing claims against German automobile manufacturers, the self-named Fünfer-Kreise ("Circle of Five"), alleging the largest known single automobile cartel in U.S. and European history.  

Matthew has experience litigating antitrust actions concerning pharmaceutical products, electronics components, employment, FRAND licensing obligations, and technology companies. At a prior plaintiffs’ firm, Matthew was an integral member of the team that collected $399 million in settlements for California purchasers of the drug Cipro, one of the largest cash settlements in the history of California antitrust law. Matthew also helped obtain settlements on behalf of direct purchasers of capacitors from members of an international price-fixing cartel, and previously pursued monopolization claims against the United Fighting Championship (the “UFC”).  Matthew additionally has experience with Foreign Sovereign Immunity Act litigation.
