Marks for the supplemental register shall not be published for or be subject to opposition, but shall be published on registration in the Official Gazette of the Patent and Trademark Office.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 he is or will be damaged by the registration of a mark on this register he may at any time, upon payment of the prescribed fee and the filing of a petition stating the ground therefor, apply to the Commissioner to cancel such registration. The Commissioner 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 Commissioner. 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.
