801.02(b) Act of 1946, Supplemental Register
Certain marks that are not eligible for registration on the Principal Register, but are capable of distinguishing an applicant’s goods or services, may be registered on the Supplemental Register. Sections 23 through 28 of the Trademark Act, 15 U.S.C. §§1091–1096, provide for registration on the Supplemental Register. This is a continuation of the register provided for in the Act of March 19, 1920. See 15 U.S.C. §1091(a). Marks registered on the Supplemental Register are excluded from receiving the advantages of certain sections of the Act of 1946. The excluded sections are listed in §26 of the Act, 15 U.S.C. §1094. See Otter Prods. LLC v. BaseOneLabs LLC, 105 USPQ2d 1252, 1256 (TTAB 2012) (finding that while ownership of a registration on the Supplemental Register established opposer’s standing to oppose registration of applicant's mark, it did not establish that opposer owned a proprietary interest in a mark).
See TMEP §§815–815.04 and 816 regarding examination procedure relating to the Supplemental Register.
An applicant may not seek registration on both the Principal and the Supplemental Register in the same application. If an applicant requests registration on both the Principal and the Supplemental Register in the same application, the examining attorney must require that the applicant amend to specify only one register, or file a request to divide under 37 C.F.R. §2.87.
A mark in an application under §66(a) of the Trademark Act, 15 U.S.C. §1141f(a), based on a request for extension of protection of an international registration to the United States, cannot be registered on the Supplemental Register. 15 U.S.C. §1141h(a)(4); 37 C.F.R. §§2.47(c), 2.75(c).
