Independence Tube Corp., 467 U.S. 752 (1984) , is a major US antitrust law case decided by the Supreme Court concerning the Pittsburgh firm Copperweld Corporation and the Chicago firm Independence Tube.  It that held that a parent company is incapable of conspiring with its wholly owned subsidiary for purposes of Section 1 of the Sherman Act because they cannot be considered separate economic entities.  Section 1 of the Sherman Act states that "Every contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the several States, or with foreign nations, is declared to be illegal."  However, for a condition of conspiracy to exist, there must be at least two parties involved.  "Copperweld" held that separate incorporation was not enough to render a parent and its subsidiary capable of conspiring, since forcibly the economic interests of a wholly owned subsidiary must be those of its parent.  It does not apply to partially owned subsidiaries.
