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 be on May 22, starting at 12:01 AM and ending at 11:59 PM ET. Additional outages will be scheduled. Please see the USPTO System Status and Availability page for more information.
During the PKI outage, users will be unable to use PKI certificates to authenticate. 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 webpage for guidance.
If you need to file a new application during this outage, please access EFS-Web with your verified account, use EFS-Web for Unregistered eFilers, 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.
