Millennium Pharmaceuticals, Inc., The Takeda Oncology Company was a leading biopharmaceutical company based in Cambridge, Massachusetts.
 Millennium has gradually been absorbed by its parent Takeda and renamed Takeda Oncology.
 The Company marketed Velcade (bortezomib) for injection, a cancer product, and has a growing clinical development pipeline of product candidates.
 Millennium's research, development and commercialization activities focused in two therapeutic areas: oncology and inflammation.
 By applying its knowledge of the human genome, understanding of disease mechanisms and industrialized drug discovery platform, Millennium developed a line of new product candidates.
 It was one of the first companies to systematically search for genes linked to disease, but none of the drugs which it is marketing or has in clinical trial, with one partial exception, have been the results of that research.
 On May 14, 2008, Japanese company Takeda Pharmaceutical announced the completion of its acquisition of Millennium for US$25.00 per share in cash—a deal worth $8.8 billion.
 Takeda completed the acquisition through a tender offer and subsequent merger of a wholly owned subsidiary of Takeda into Millennium.

Copperweld Corp. v. 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.
