JP Morgan Chase, VantageScore antitrust litigation), and groundbreaking defeats of class certification (Asacol antitrust litigation, Blades v. Monsanto).

Jack successfully has represented clients in numerous trials and other litigation settings against private parties, federal prosecutors, and state attorneys general. He also has represented many leading global companies in class action litigation matters at the cutting edge of antitrust and intellectual property.
