The legitimate proprietary interest of the United States and of a contractor in technical or other data shall be defined in regulations prescribed as part of the single system of Government-wide procurement regulations as defined in section

Such regulations may not impair any right of the United States or of any contractor with respect to patents or copyrights or any other right in technical data otherwise established by law. Such regulations shall provide, with respect to executive agencies that are subject to the provisions of title III of the Federal Property and Administrative Services Act of 1949 [
