37 C.F.R. § 2.133 Amendment of application or registration during proceedings.
Title 37 - Patents, Trademarks, and Copyrights
(a) An application involved in a proceeding may not be amended in substance nor may a registration be amended or disclaimed in part, except with the consent of the other party or parties and the approval of the Trademark Trial and Appeal Board, or except upon motion. (b) If, in an inter partes proceeding, the Trademark Trial and Appeal Board finds that a party whose application or registration is the subject of the proceeding is not entitled to registration in the absence of a specified restriction to the involved application or registration, the Trademark Trial and Appeal Board will allow the party time in which to file a request that the application or registration be amended to conform to the findings of the Trademark Trial and Appeal Board, failing which judgment will be entered against the party. (c) Geographic limitations will be considered and determined by the Trademark Trial and Appeal Board only in the context of a concurrent use registration proceeding. (d) A plaintiff's pleaded registration will not be restricted in the absence of a counterclaim to cancel the registration in whole or in part, except that a counterclaim need not be filed if the registration is the subject of another proceeding between the same parties or anyone in privity therewith.
