PKI Outage for EFS-Web and Private PAIR

PKI authentication for EFS-Web and Private PAIR will be unavailable starting 12:01 a.m., Thursday, May 30, and ending at 11:59 p.m., Friday, May 31 ET. Additional outages will be scheduled. Please see the USPTO Systems Status and Availability page for more information.

During the PKI outage period, customers will be unable to use PKI certificates to authenticate. This PKI outage does not affect customers accessing EFS-Web and Private PAIR with a verified account. 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 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.
