Summary

Anyone can ask the Patent and Trademark Office to recheck a trademark registration if they think the mark was not actually used in business for some or all of the listed goods or services on or before the relevant date. For marks filed based on actual use, the relevant date is the date the application was first filed. For marks filed on intent-to-use (or changed to intent-to-use), the relevant date is either the date an amendment saying the mark was in use was filed or the date the deadline to file a statement of use (including approved extensions) ended. A petition must name the registration, point out which goods or services are questioned, include a signed statement describing the reasonable steps taken to check use and any facts supporting the claim, provide supporting evidence, and include the fee. The Director will look at each claimed non-use and decide if there is enough initial evidence to start a reexamination for those goods or services. The owner and the petitioner will be told and sent the petition and evidence. The Director will make rules about what counts as a reasonable check and what evidence may help, but the Director’s choice to start or not start a reexamination is final. Reexaminations follow set procedures, may have special time limits, and can lead to cancellation of parts of the registration if use before the relevant date is not shown. The Director can also start a reexamination on their own. Petitions or Director actions must be filed within 5 years after the registration date for marks registered based on use. While a reexamination is pending, no later reexamination can be started for the same goods or services, and if a reexamination already found use and did not cancel those items, no further ex parte reexamination can be brought for them. The same rules apply to registrations on the Supplemental Register as appropriate.

(a)Petition for reexamination
Any person may file a petition to reexamine a registration of a mark on the basis that the mark was not in use in commerce on or in connection with some or all of the goods or services recited in the registration on or before the relevant date.
(b)Relevant date
In this section, the term “relevant date” means, with respect to an application for the registration of a mark with an initial filing basis of— (1)
(2)section 1051(b) of this title or amended at any point to be filed pursuant to section 1051(b) of this title, the date on which—
(A)an amendment to allege use under section 1051(c) of this title was filed; or
(B)the period for filing a statement of use under section 1051(d) of this title expired, including all approved extensions thereof.
(c)Requirements for the petition
A petition filed under subsection (a), together with any supporting documents, shall—
(1)identify the registration that is the subject of the petition;
(2)identify each good and service recited in the registration for which it is alleged that the mark was not in use in commerce on or in connection with on or before the relevant date;
(3)include a verified statement that sets forth—
(A)the elements of the reasonable investigation the petitioner conducted to determine that the mark was not in use in commerce on or in connection with the goods and services identified in the petition on or before the relevant date; and
(B)any additional facts that support the allegation that the mark was not in use in commerce on or before the relevant date on or in connection with the identified goods and services;
(4)include supporting evidence on which the petitioner relies; and
(5)be accompanied by the fee prescribed by the Director.
(d)Initial determination; institution
(1)Prima facie case determination, institution, and notification
The Director shall, for each good or service identified under subsection (c)(2), determine whether the petition sets forth a prima facie case of the mark having not been in use in commerce on or in connection with each such good or service, institute an ex parte reexamination proceeding for each good or service for which the Director determines that the prima facie case has been set forth, and provide a notice to the registrant and petitioner of the determination of whether or not the proceeding was instituted. Such notice shall include a copy of the petition and any supporting documents and evidence that were included with the petition.
(2)Reasonable investigation guidance
The Director shall promulgate regulations regarding what constitutes a reasonable investigation under subsection (c)(3) and the general types of evidence that could support a prima facie case that the mark was not in use in commerce on or in connection with a good or service on or before the relevant date, but the Director shall retain discretion to determine whether a prima facie case is set out in a particular proceeding.
(3)Determination by Director
Any determination by the Director whether or not to institute a reexamination proceeding under this section shall be final and non-reviewable, and shall not prejudice any party’s right to raise any issue and rely on any evidence in any other proceeding, except as provided in subsection (j).
(e)Reexamination procedures
The procedures for reexamination shall be the same as the procedures established under section 1062(b) of this title except that the Director shall promulgate regulations establishing and governing a proceeding under this section, which may include regulations that—
(1)set response and extension times particular to this type of proceeding, which, notwithstanding section 1062(b)(3) of this title, need not be extendable to 6 months;
(2)set limits governing the timing and number of petitions filed for a particular registration or by a particular petitioner or real parties in interest; and
(3)define the relation of a reexamination proceeding under this section to other proceedings concerning the mark.
(f)Registrant’s evidence of use
A registrant’s documentary evidence of use shall be consistent with when a mark shall be deemed to be in use in commerce under the definition of “use in commerce” in section 1127 of this title, but shall not be limited in form to that of specimens as provided in section 1051(a) of this title.
(g)Examiner’s decision; order to cancel
For each good or service for which it is determined that the registration should not have issued because the mark was not in use in commerce on or before the relevant date, the examiner shall find that the registration should be cancelled for each such good or service. Unless overturned on review of the examiner’s decision, the Director shall issue an order cancelling the registration, in whole or in part, after the time for appeal has expired or any appeal proceeding has terminated.
(h)Reexamination by Director (i) Time for institution
(1)In general
The Director may, on the Director’s own initiative, institute an ex parte reexamination proceeding if the Director discovers information that supports a prima facie case of the mark having not been used in commerce on or in connection with some or all of the goods or services covered by the registration on or before the relevant date. The Director shall promptly notify the registrant of such determination, at which time reexamination shall proceed according to the same procedures established pursuant to subsection (e). If the Director determines, based on the Director’s own initiative, to institute an ex parte reexamination proceeding, the Director shall transmit or make available the information that formed the basis for that determination as part of the institution notice.
(2)Rule of construction
Nothing in this subsection shall be construed to limit any other authority of the Director.
(j)Limitation on later ex parte reexamination proceedings
(1)No co-pending proceedings
With respect to a particular registration, while an ex parte reexamination proceeding is pending, no later ex parte reexamination proceeding may be instituted with respect to the same goods or services that are the subject of a pending ex parte reexamination proceeding.
(2)Estoppel
With respect to a particular registration, for any goods or services previously subject to an instituted ex parte reexamination proceeding for which, in that proceeding, it was determined that the registrant had used the mark for particular goods or services before the relevant date, and the registration was not cancelled as to those goods or services, no further ex parte reexamination proceedings may be initiated as to those goods or services, regardless of the identity of the petitioner.
(k)Supplemental register
The provisions of subsection (b) apply, as appropriate, to registrations under section 1091 of this title. Nothing in this section shall be construed to limit the timing of a cancellation action under section 1092 of this title.
