Planned Events

Vendor Portal Maintenance

The USPTO will perform system maintenance on the Vendor Portal beginning at 12:01 a.m., Thursday, May 23 and ending at 7 a.m., Thursday, May 23 ET.

Vendor Portal will be unavailable during the maintenance period.


PKI Outage for EFS-Web and Private PAIR

The USPTO will have a series of upcoming outages to begin the phased termination of Public Key Infrastructure (PKI) certificates for Electronic Filing System-Web (EFS-Web) and Private Patent Application Information Retrieval (PAIR). This will not affect users accessing EFS-Web and Private PAIR with a verified account.

The first PKI outage will begin at 12:01 a.m., Wednesday, May 22 and ending at 11:59 p.m., Wednesday, May 22 ET.

Additional outages will be scheduled. Please continue to revisit this page for more information.

During the PKI outage period, users will be unable to use PKI certificates to authenticate and will be unable to access EFS-Web for Unregistered eFilers. However, authentication via verified accounts to access EFS-Web and Private PAIR will be available. Please ensure that you migrated the proper PKI to the correct account prior to the outage. If you have not migrated or need to sponsor support staff, please visit the Authentication Change website for guidance.

If you need to file a new application during this outage, please access EFS-Web with your verified account, or use EFS-Web Contingency. If you need to file a follow-on submission and do not have a verified account, please use an alternative filing method.

If you have questions or need to reverse an incorrectly migrated account, please contact the Patent Electronic Business Center (EBC) at or 866-217-9197.
