15 USC 1091 - Supplemental register

(a) Marks registerable 
In addition to the principal register, the Director shall keep a continuation of the register provided in paragraph (b) of section 1 of the Act of March 19, 1920, entitled An Act to give effect to certain provisions of the convention for the protection of trademarks and commercial names, made and signed in the city of Buenos Aires, in the Argentine Republic, August 20, 1910, and for other purposes, to be called the supplemental register. All marks capable of distinguishing applicants goods or services and not registrable on the principal register provided in this chapter, except those declared to be unregistrable under subsections (a), (b), (c), (d), and (e)(3) of section 1052 of this title, which are in lawful use in commerce by the owner thereof, on or in connection with any goods or services may be registered on the supplemental register upon the payment of the prescribed fee and compliance with the provisions of subsections (a) and (e) of section 1051 of this title so far as they are applicable. Nothing in this section shall prevent the registration on the supplemental register of a mark, capable of distinguishing the applicants goods or services and not registrable on the principal register under this chapter, that is declared to be unregistrable under section 1052 (e)(3) of this title, if such mark has been in lawful use in commerce by the owner thereof, on or in connection with any goods or services, since before December 8, 1993.
(b) Application and proceedings for registration 
Upon the filing of an application for registration on the supplemental register and payment of the prescribed fee the Director shall refer the application to the examiner in charge of the registration of marks, who shall cause an examination to be made and if on such examination it shall appear that the applicant is entitled to registration, the registration shall be granted. If the applicant is found not entitled to registration the provisions of subsection (b) of section 1062 of this title shall apply.
(c) Nature of mark 
For the purposes of registration on the supplemental register, a mark may consist of any trademark, symbol, label, package, configuration of goods, name, word, slogan, phrase, surname, geographical name, numeral, device, any matter that as a whole is not functional, or any combination of any of the foregoing, but such mark must be capable of distinguishing the applicants goods or services.

15 USC 1092 - Publication; not subject to opposition; cancellation

Marks for the supplemental register shall not be published for or be subject to opposition, but shall be published on registration in the Official Gazette of the Patent and Trademark Office. Whenever any person believes that such person is or will be damaged by the registration of a mark on the supplemental register
(1) for which the effective filing date is after the date on which such persons mark became famous and which would be likely to cause dilution by blurring or dilution by tarnishment under section 1125 (c) of this title; or
(2) on grounds other than dilution by blurring or dilution by tarnishment,

such person may at any time, upon payment of the prescribed fee and the filing of a petition stating the ground therefor, apply to the Director to cancel such registration. The Director shall refer such application to the Trademark Trial and Appeal Board which shall give notice thereof to the registrant. If it is found after a hearing before the Board that the registrant is not entitled to registration, or that the mark has been abandoned, the registration shall be canceled by the Director. However, no final judgment shall be entered in favor of an applicant under section 1051 (b) of this title before the mark is registered, if such applicant cannot prevail without establishing constructive use pursuant to section 1057 (c) of this title.

15 USC 1093 - Registration certificates for marks on principal and supplemental registers to be different

Registration of a mark on the supplemental register, or under the Act of March 19, 1920, shall not preclude registration by the registrant on the principal register established by this chapter.
