37 C.F.R. §§ 2.71–2.75

The applicant may amend the application to clarify or limit, but not to broaden, the identification of goods and/or services or the description of the nature of the collective membership organization.

The applicant may amend the dates of use, provided that the amendment is verified, except that the following amendments are not permitted:

The applicant may amend the application to correct the name of the applicant, if there is a mistake in the manner in which the name of the applicant is set out in the application. The amendment must be verified. However, the application cannot be amended to set forth a different entity as the applicant. An application filed in the name of an entity that did not own the mark as of the filing date of the application is void.

An amendment that would materially alter the certification statement specified in § 2.45(a)(4)(i)(A) or (a)(4)(ii)(A) will not be permitted.

In an application based on use in commerce under section 1(a) of the Act, the applicant may amend the description or drawing of the mark only if:

In an application based on a bona fide intention to use a mark in commerce under section 1(b) of the Act, the applicant may amend the description or drawing of the mark only if:

In an application based on a claim of priority under section 44(d) of the Act, or on a mark duly registered in the country of origin of the foreign applicant under section 44(e) of the Act, the applicant may amend the description or drawing of the mark only if:

Form of Amendment. Amendments should be set forth clearly and completely. Applicant should either set forth the entire wording, including the proposed changes, or, if it would be more efficient, indicate which words should be added and which words should be deleted. The examining attorney may require the applicant to rewrite the entire amendment, if necessary for clarification of the record.

Signature. A request for amendment of an application must be signed by the applicant, someone with legal authority to bind the applicant (e.g., a corporate officer or general partner of a partnership), or a practitioner qualified to practice under § 11.14 of this chapter, in accordance with the requirements of § 2.193(e)(2). If the amendment requires verification, see § 2.2(n).

An application for registration on the Principal Register under section 1(a) or 44 of the Act may be changed to an application for registration on the Supplemental Register and vice versa by amending the application to comply with the rules relating to the appropriate register, as the case may be.

An application under section 1(b) of the Act may be amended to change the application to a different register only after submission of an acceptable amendment to allege use under § 2.76 or statement of use under § 2.88. When such an application is changed from the Principal Register to the Supplemental Register, the effective filing date of the application is the date of the filing of the allegation of use under section 1(c) or 1(d) of the Act.

In an application under section 66(a) of the Act, the applicant may not amend the application to the Supplemental Register.
