204.01 Filing Date Cancelled if Minimum Filing Requirements not Met
Applications under §1 or §44 of the Trademark Act are initially assigned a filing date and serial number and then reviewed for compliance with the minimum requirements for receipt of a filing date set forth in 37 C.F.R. §2.21(a). If the minimum filing requirements have not been met, the USPTO cancels the filing date and serial number, refunds any filing fee submitted, and sends a notice to the applicant explaining why the application is defective.
See TMEP §204.02 regarding the procedures for requesting review of the denial of a filing date by the Office of the Deputy Commissioner for Trademark Examination Policy.
