TMEP § 1711
If an application is denied a filing date and the applicant wants the filing date restored, the usual procedure is to file a petition to the Director under 37 C.F.R. §2.146.
However, the applicant may request restoration of the filing date without a formal petition in either of the following situations:
In these situations, a staff attorney or paralegal in the Office of the Deputy Commissioner for Trademark Examination Policy may restore the original filing date without a formal petition or a petition fee. In all other circumstances, the applicant must file a formal petition to the Director, including the petition fee required by 37 C.F.R. §2.6.
Procedure for Filing Request to Restore a Filing Date. In any request to restore an application filing date, the applicant should first refile the application using the trademark electronic filing system and pay the application filing fee required by 37 C.F.R. §2.6(a)(1). After the applicant receives a new serial number, the applicant should file a Request to Restore Filing Date form in the trademark electronic filing system. The request must be filing using the new serial number and: (1) include the cancelled serial number; (2) state the reason(s) why the applicant believes the filing date was denied in error; and (3) include a copy of any Notice of Incomplete Trademark Application received from the USPTO. See TMEP §204.02.
Time Limit for Filing Request to Restore a Filing Date. All requests to restore filing dates, whether made by formal petition or informal request, must be filed promptly. If the USPTO issues a notice advising the applicant of the denial or cancellation of the filing date, the request to restore the filing date must be filed within two months of the issue date of the action, or it will be denied as untimely. 37 C.F.R. §2.146(d). Although applicants have two months from the issue date of this notice to file a request to restore the original filing date, it is recommended that an applicant promptly refile the application, and file the request to restore the filing date immediately upon receipt of the new serial number, to minimize the delay in receiving a filing date, and to reduce the impact on third parties who may rely on the current filing date information in the Trademark database.
Furthermore, applicants must exercise due diligence in monitoring the status of applications. 37 C.F.R. §2.23(d)(1); TMEP §§108.03, 1705.05. That is, an applicant must check the status of a pending application every six months between the filing date of the application and issuance of a registration. 37 C.F.R. §2.23(d)(1).
Evidence of Missing Element Required. If the USPTO denies a filing date due to the omission of an element required by 37 C.F.R. §2.21, and the applicant declares that the missing element was in fact included with the application as filed, the Director will not grant a petition to restore or reinstate the filing date unless: (1) the applicant provides evidence that the element was received in the USPTO on the requested filing date; or (2) there is an image of the element in the USPTO’s Trademark database.
