§1066b Ex Parte Reexamination

Title 15 › Chapter 22— TRADEMARKS › Subchapter I— THE PRINCIPAL REGISTER › § 1066b

Summary

Anyone can ask the patent office to reexamine a trademark if they believe the mark was not being used in commerce for some or all of the listed goods or services by a key date. Relevant date: either the original filing date for certain filings, or the date use was claimed or the statement-of-use period (with extensions) ended for other filings. The petition must name the registration, say which goods or services are at issue, describe the investigator’s steps and other facts that support the claim, include evidence, and pay the required fee. The Director will check each item and decide if the petition shows a basic (prima facie) case. If so, the Director starts a reexamination and tells the registrant and petitioner, sending them the petition and evidence. The Director will make rules about what counts as a reasonable investigation and acceptable evidence, and the decision to start a reexamination is final and not reviewable. The reexamination follows set procedures, allows different timing and limits, and accepts different types of proof of use. If the examiner finds the mark was not used by the relevant date for some goods or services, those parts of the registration will be canceled. The Director can also start a reexamination on the Director’s own, and petitions or Director-initiated actions must be filed no later than 5 years after the registration date. While one reexamination for particular goods or services is pending, no later reexamination can be started for those same goods or services, and goods or services previously found to have been used before the relevant date may not be reexamined again.

Commerce and Trade — Source: USLM XML via OLRC

(a)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)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)section 1051(a) of this title and not amended at any point to be filed pursuant to section 1051(b) of this title, the date on which the application was initially filed; or
(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)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)(1)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)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)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)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)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)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)(1)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)Nothing in this subsection shall be construed to limit any other authority of the Director.
(i)A petition for ex parte reexamination may be filed, or the Director may institute on the Director’s own initiative an ex parte reexamination proceeding, at any time not later than 5 years after the date of registration of a mark registered based on use in commerce.
(j)(1)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)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)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.
