The Motion Picture Patents Company, founded in December 1908 and effectively terminated in 1915 after it lost a federal antitrust suit, was a trust of all the major US film companies and local foreign-branches, the leading film distributor and the biggest supplier of raw film stock, Eastman Kodak. The MPPC ended the domination of foreign films on US screens, standardized the manner in which films were distributed and exhibited within the US, and improved the quality of US motion pictures by internal competition. It also discouraged its members' entry into feature film production, and the use of outside financing, both to its members' eventual detriment.

United States v. Motion Picture Patents Co., 225 F. 800, was a civil antitrust prosecution overlapping to some extent with the issues in the decision in the Supreme Court's Motion Picture Patents case. After the trial court found that the defendants violated §§ 1 and 2 of the Sherman Act by establishing control over "trade in films, cameras, projecting machines, and other accessories of the motion picture business," by their patent licensing practices and other conduct, they appealed to the Supreme Court. After the Supreme Court's 1917 decision in Motion Picture Patents Co. v. Universal Film Manufacturing Co., however, the parties dismissed the appeal by stipulation in 1918 that the decision had made the defendants' appeal futile.
