§ 2.71 Amendments to correct informalities. The applicant may amend the application during the course of examination, when required by the Office or for other reasons. ( a ) 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.
( b ) ( 1 ) If the verified statement in an application under § 2.33 is unsigned or signed by the wrong party, the applicant may submit a substitute verification.
( 2 ) If the verified statement in a statement of use under § 2.88, or a request for extension of time to file a statement of use under § 2.89, is unsigned or signed by the wrong party, the applicant must submit a substitute verification before the expiration of the statutory deadline for filing the statement of use.
( c ) The applicant may amend the dates of use, provided that the amendment is verified, except that the following amendments are *not* permitted: ( 1 ) In an application under section 1(a) of the Act, the applicant may not amend the application to specify a date of use that is subsequent to the filing date of the application;
( 2 ) In an application under section 1(b) of the Act, after filing a statement of use under § 2.88, the applicant may not amend the statement of use to specify a date of use that is subsequent to the expiration of the deadline for filing the statement of use.
