Once you receive a serial number for your application, you can check the status of your application through the Trademark Status and Document Retrieval (TSDR) system. If you do not have access to the Internet, you can call the Trademark Assistance Center at 1-800-786-9199 to request a status check. You should check on the status of your pending application every 3-4 months. If the USPTO has taken any action, you may need to respond promptly. All USPTO actions are available for viewing using TSDR.
