Title 15 › CHAPTER 22 — TRADEMARKS › SUBCHAPTER I — THE PRINCIPAL REGISTER › § 1066b
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.
