U.S. Patent Act
..Part IV. Patent Cooperation Treaty
....Chapt. 37. National Stage
==========================================================
An international application designating the United States, shall not be accepted by the Patent and Trademark Office for the national stage if it was filed by anyone not qualified under chapter 11 of this title [35 USCS Sects. 111 et seq.] to be an applicant for the purpose of filing a national application in the United States. Such international applications shall not serve as the basis for the benefit of an earlier filing date under section 120 of this title[35 USCS Sect. 120] in a subsequently filed application, but may serve as the basis for a claim of the right of priority under section 119 of this title 35 USCS Sect. 119], if the United States was not the sole country designated in such international application.
