Actavis (resulting in a complete defense verdict). He has successfully defended individuals against charges of price-fixing, and a major motion picture studio against claims of monopolization and tying; served as antitrust counsel to major trade associations on issues such as standard-setting and denials of membership; has represented corporations in matters before the Federal Trade Commission; and was actively involved in the firm’s representation of the nine non-settling plaintiff States in the Microsoft antitrust case. 

In other areas, Mr. Pitt has successfully represented a group of corporate executives in lawsuits alleging wrongful termination and shareholder derivative claims; has secured dismissals from multiple U.S. jurisdictions, on forum non conveniens grounds, of a major tort action based upon events allegedly occurring in Latin America; and has conducted internal corporate investigations into allegations of wrongdoing under the Foreign Corrupt Practices Act, the federal False Claims Act, the anti-kickback laws, and the Food, Drug, and Cosmetic Act. He has also secured the dismissal of civil RICO and Lanham Act claims in the Southern District of New York and the Second Circuit (where he successfully argued the appeal on behalf of his client); and has litigated several highly contested and sensitive private disputes for individual clients, involving considerable assets.
