(a) Revocation.

(1) Authority to represent an applicant, registrant or party to a proceeding before the Office may be revoked at any stage in the proceedings of a trademark case, upon written notification signed by the applicant, registrant, or party to the proceeding, or by someone with legal authority to bind the applicant, registrant, or party (e.g., a corporate officer or general partner of a partnership). In the case of joint applicants or joint registrants, all must sign.

(2) When a power of attorney is revoked, the Office will communicate directly with the applicant, registrant, or party to the proceeding, or with the new attorney or domestic representative if appropriate.

(3) A request to change the correspondence address does not revoke a power of attorney.

(4) A new power of attorney that meets the requirements of §2.17(c) will be treated as a revocation of the previous power.

If the requirements of §11.116 of this chapter are met, a practitioner authorized to represent an applicant, registrant, or party to a proceeding in a trademark case may withdraw upon application to and approval by the Director or, when applicable, upon motion granted by the Trademark Trial and Appeal Board.

(2) A statement of the reason(s) for the request to withdraw; and

(3) Either
