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 USPTO.gov account. Authentication via verified USPTO.gov accounts to access EFS-Web and Private PAIR will be available. Please ensure that you migrated the proper PKI to the correct USPTO.gov 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 USPTO.gov 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 USPTO.gov 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 ebc@uspto.gov or 866-217-9197.
