Response Time Period

The Office action (official letter) you receive from the USPTO will specify the time period in which you must respond. In most cases, the USPTO must receive a response to your Office action within six (6) months of the date specified in the heading of the e-mail notification that you receive when an Office action issues. In certain limited circumstances, the Office action may specify a different response period. However, trademark examining attorneys have no discretion to extend the time period for filing a response. Because the length of the response period may vary, please confirm the specific time period in your Office action. If you do not respond within that time period, the USPTO will declare your application abandoned, the application process will end, and your trademark will fail to register. 

To ensure your response is timely, the USPTO strongly recommends that you file your response online through the Trademark Electronic Application System (TEAS).  If filed through TEAS, the filing date of your response is the date when the USPTO receives the transmission. Eastern Time controls for purposes of determining whether your TEAS response form was timely filed. Any submission that arrives as of 11:59 p.m. Eastern Time will be given that day's filing date regardless of the USPTO's regular business hours.

If you are filing a response using regular mail, the filing date of the response is the date of receipt in the USPTO, not the postmarked date. To ensure that your response is timely, you may add to the end of the response a properly completed "certificate of mailing" for a response submitted by mail. You should retain a photocopy of your response with the signed certificate in the event that the response is lost or misplaced by the USPTO. For additional information on attaching a certificate of mailing, see TMEP Section 305.02
