TMEP § 714.05(a)(ii)
If the applicant responds to a nonfinal Office action requiring an amendment to the identification of goods/services, and the examining attorney determines that the identification is still unacceptable, generally the examining attorney must issue a final requirement to amend the identification of goods/services. There are only three exceptions to this rule:
If the examining attorney issues a nonfinal action requiring amendment of the identification because it is indefinite, and the applicant responds with an amended identification that is definite, but is otherwise unacceptable (e.g., because it includes a registered trademark or service mark (see TMEP §1402.09)), this is not considered a new issue, and the examining attorney must issue a final Office action requiring amendment of the identification.
However, if the examining attorney issues a final action requiring amendment of the identification because it is indefinite, and the applicant responds with an amended identification that is definite but is otherwise unacceptable (e.g., because it includes a registered mark), the examining attorney should treat the response as incomplete, and grant the applicant additional time to cure this deficiency, pursuant to 37 C.F.R. §2.65(a)(2). See TMEP §718.03(b) for further information about granting an applicant additional time to perfect an incomplete response. Examining attorneys are encouraged to try to resolve these issues by examiner’s amendment.
