Additional Patent Electronic Systems
Please check the USPTO Systems Status and Availability page for operating status of the following systems that provide similar functionality as Patent Center:
EFS-Web for Registered eFilers
Enhanced filing, follow-on processing, saved submissions and more.
EFS-Web for Unregistered eFilers
Basic initial filing of new patent applications. Note: Unregistered eFilers are not permitted to file follow-on submissions or fees in EFS-Web. We advise eFilers to pay fees online as part of the initial application submission or use an alternative filing method to pay fees on the same day to avoid a late surcharge.
Basic initial filing of new patent applications when the primary portal to EFS-Web has an unscheduled outage. Learn more about EFS-Web Contingency.
Securely access information on your pending patent application
For documents and status on publicly available patents and applications
Alternative filing methods
If you need to file a new patent application, follow-on submission to existing application, or fee payment when EFS-Web, EFS-Web Contingency, and Patent Center are unavailable, please use an alternative filing method.
If you need assistance with Patent Center, EFS-Web, or PAIR, please contact the Patent Electronic Business Center at 866-217-9197 (toll free) or email EBC@uspto.gov .
