37 C.F.R. § 2.63 Reexamination.
Title 37 - Patents, Trademarks, and Copyrights
(a) After response by the applicant, the application will be reexamined or reconsidered. If registration is again refused or any formal requirement[s] is repeated, but the examiner's action is not stated to be final, the applicant may respond again. (b) After reexamination the applicant may respond by filing a timely petition to the Director for relief from a formal requirement if: (1) The requirement is repeated, but the examiner's action is not made final, and the subject matter of the requirement is appropriate for petition to the Director (see §2.146(b)); or (2) the examiner's action is made final and such action is limited to subject matter appropriate for petition to the Director. If the petition is denied, the applicant shall have until six months from the date of the Office action which repeated the requirement or made it final or thirty days from the date of the decision on the petition, whichever date is later, to comply with the requirement. A formal requirement which is the subject of a petition decided by the Director may not subsequently be the subject of an appeal to the Trademark Trial and Appeal Board. [48 FR 23134, May 23, 1983]
