37 C.F.R. §§ 2.111–2.115

A cancellation proceeding is commenced by filing in the Office a timely petition for cancellation with the required fee.

Any person who believes that he, she, or it is or will be damaged by a registration may file a petition, addressed to the Trademark Trial and Appeal Board, for cancellation of the registration in whole or in part. The petition for cancellation need not be verified, but must be signed by the petitioner or the petitioner's attorney, as specified in § 11.1 of this chapter, or other authorized representative, as specified in § 11.14(b) of this chapter. Electronic signatures pursuant to § 2.193(c) are required for petitions submitted electronically via ESTTA. The petition for cancellation may be filed at any time in the case of registrations on the Supplemental Register or under the Act of 1920, or registrations under the Act of 1881 or the Act of 1905, which have not been published under section 12(c) of the Act, on any ground specified in section 14(3) or section 14(5) of the Act, or at any time after the three-year period following the date of registration on the ground specified in section 14(6) of the Act. In all other cases, including nonuse claims not specified in section 14(6), the petition for cancellation and the required fee must be filed within five years from the date of registration of the mark under the Act or from the date of publication under section 12(c) of the Act.

The petition for cancellation must be accompanied by the required fee for each party joined as petitioner for each class in the registration(s) for which cancellation is sought (see § 2.6). A petition cannot be filed via ESTTA unless the petition is accompanied by a fee that is sufficient to pay in full for each named petitioner to seek cancellation of the registration(s) in each class specified in the petition. A petition filed in paper form that is not accompanied by a fee sufficient to pay in full for each named petitioner for each class in the registration(s) for which cancellation is sought may not be instituted.

The filing date of a petition for cancellation is the date of electronic receipt in the Office of the petition and required fee. In the rare instances that filing by paper is permitted under these rules, the filing date of a petition for cancellation will be determined in accordance with §§ 2.195 through 2.198.

The petition for cancellation must set forth a short and plain statement showing why the petitioner believes he, she or it is or will be damaged by the registration, state the ground for cancellation, and indicate, to the best of petitioner's knowledge, the name and address, and a current email address(es), of the current owner of the registration. ESTTA requires the petitioner to select relevant grounds for petition to cancel. The required accompanying statement supports and explains the grounds.

When appropriate, petitions for cancellation of different registrations owned by the same party may be joined in a consolidated petition for cancellation. The required fee must be included for each party joined as a petitioner for each class sought to be cancelled in each registration against which the petition for cancellation has been filed.

When a petition for cancellation in proper form (see §§ 2.111 and 2.112) has been filed and the correct fee has been submitted, the Trademark Trial and Appeal Board shall prepare a notice of institution which shall identify the proceeding as a cancellation, number of the proceeding and the registration(s) involved; and shall designate a time, not less than thirty days from the mailing date of the notice, within which an answer must be filed. The notice, which will include a Web link or Web address to access the electronic proceeding record, constitutes service to the registrant of the petition to cancel.

The Board shall forward a copy of the notice to petitioner, as follows:

When the party alleged by the petitioner, pursuant to § 2.112(a), as the current owner of the registration(s) is not the record owner, a courtesy copy of the notice with a Web link or Web address to access the electronic proceeding record shall be forwarded to the alleged current owner. The alleged current owner may file a motion to be joined or substituted as respondent.

The petition for cancellation or counterclaim petition for cancellation may be withdrawn without prejudice before the answer is filed. After the answer is filed, such petition or counterclaim petition may not be withdrawn without prejudice except with the written consent of the registrant or the registrant's attorney or other authorized representative.
