§ 2.173 Amendment of registration. ( a ) *Form of amendment.* The owner of a registration may apply to amend a registration or to disclaim part of the mark in the registration. The owner must submit a written request specifying the amendment or disclaimer. If the registration is involved in an *inter partes* proceeding before the Trademark Trial and Appeal Board, the request must be filed by appropriate motion to the Board.
( b ) *Requirements for request.* A request for amendment or disclaimer must: ( 1 ) Include the fee required by § 2.6;
( 2 ) Be verified and signed in accordance with § 2.193(e)(6); and
( 3 ) If the amendment involves a change in the mark: one new specimen per class showing the mark as used on or in connection with the goods, services, or collective membership organization; a verified statement that the specimen was in use in commerce at least as early as the filing date of the amendment; and a new drawing of the amended mark. When requested by the Office, additional specimens must be provided.
( 4 ) The Office may require the owner to furnish such specimens, information, exhibits, and affidavits or declarations as may be reasonably necessary to the proper examination of the amendment.
( c ) *Registration must still contain registrable matter.* The registration as amended must still contain registrable matter, and the mark as amended must be registrable as a whole.
( d ) *Amendment may not materially alter the mark.* An amendment or disclaimer that materially alters the character of the mark will not be permitted, in accordance with section 7(e) of the Act.
( e ) *Amendment of identification of goods, services, or collective membership organization.* No amendment in the identification of goods or services, or description of the nature of the collective membership organization, in a registration will be permitted except to restrict the identification or to change it in ways that would not require republication of the mark.
( f ) *Amendment of certification statement for certification marks.* An amendment of the certification statement specified in § 2.45(a)(4)(i)(A) or (a)(4)(ii)(A) that would materially alter the certification statement will not be permitted, in accordance with section 7(e) of the Act.
( g ) *Conforming amendments may be required.* If the registration includes a disclaimer, description of the mark, or other miscellaneous statement, any request to amend the registration must include a request to make any necessary conforming amendments to the disclaimer, description, or other statement.
( h ) *Elimination of disclaimer.* No amendment seeking the elimination of a disclaimer will be permitted, unless deletion of the disclaimed portion of the mark is also sought.
( i ) *No amendment to add or delete section 2(f) claim of acquired distinctiveness.* An amendment seeking the addition or deletion of a claim of acquired distinctiveness will not be permitted.
