The Robinson-Patman Act was approved by the President on June 19, 1936. The purpose of the act was to amend section 2 of the Clayton Act, which prohibited price discriminations in interstate commerce. Congress, by amending section 2 of the Clayton Act, broadened the scope of the section by extending its purposes and prohibitions to price discriminations not formerly covered and by prohibiting other forms of discrimination which give favored purchasers undue cost advantages over their non-favored competitors. It also reduced the extent of requisite competitive injury.
