1605.06 Section 14 Limitation is Independent of §15 Affidavit or Declaration
Section 14 of the Trademark Act, 15 U.S.C. §1064, limits the grounds that a third party can raise in a petition to cancel a mark registered on the Principal Register when the petition is filed more than five years from the date of registration or publication under §12(c). This limitation of grounds does not depend on the filing of a §15 affidavit or declaration. Trademark Trial and Appeal Board Manual of Procedure (“TBMP”) §307.02(b).
