The Clayton Antitrust Act of 1914, (October 15, 1914, ch. 323, 38 Stat. 730, codified at 15 U.S.C. § 12–27, 29 U.S.C. § 52–53), was enacted in the United States to add further substance to the U.S. antitrust law regime by seeking to prevent anticompetitive practices in their incipiency. That regime started with the Sherman Antitrust Act of 1890, the first Federal law outlawing practices considered harmful to consumers (monopolies and cartels). The Clayton act specified particular prohibited conduct, the three-level enforcement scheme,the exemptions, and the remedial measures.
