15 U.S.C. 1-7

15 U.S.C. §5: Bringing in additional parties

Whenever it shall appear to the court before which any proceeding under section 4 of this title may be pending, that the ends of justice require that other parties should be brought before the court, the court may cause them to be summoned, whether they reside in the district in which the court is held or not; and subpoenas to that end may be served in any district by the marshal thereof.

15 U.S.C. §6: Forfeiture of property in transit

Any property owned under any contract or by any combination, or pursuant to any conspiracy (and being the subject thereof) mentioned in section 1 of this title, and being in the course of transportation from one State to another, or to a foreign country, shall be forfeited to the United States, and may be seized and condemned by like proceedings as those provided by law for the forfeiture, seizure, and condemnation of property imported into the United States contrary to law.

15 U.S.C. §6a: Conduct involving trade or commerce with foreign nations

Sections 1 to 7 of this title shall not apply to conduct involving trade or commerce (other than import trade or import commerce) with foreign nations unless—

(1)  such conduct has a direct, substantial, and reasonably foreseeable effect—

(A)  on trade or commerce which is not trade or commerce with foreign nations, or on import trade or import commerce with foreign nations; or

(B)  on export trade or export commerce with foreign nations, of a person engaged in such trade or commerce in the United States; and

(2) such effect gives rise to a claim under the provisions of sections 1 to 7 of this title, other than this section.

If sections 1 to 7 of this title apply to such conduct only because of the operation of paragraph (1) (B), then sections 1 to 7 of this title shall apply to such conduct only for injury to export business in the United States.
