PKI outage for EFS-Web and Private PAIR

PKI authentication for EFS-Web and Private PAIR will be unavailable starting on Wednesday, June 5 at 12:01 a.m. ET, until further notice. Additional information and updates will continue to be posted to this USPTO systems status and availability page

Please use your verified USPTO.gov account to access EFS-Web for registered eFilers and Private PAIR

If you need to file a new patent application and do not have a verified USPTO.gov account, you can use EFS-Web for unregistered eFilers or EFS-Web contingency. If you need to file a follow-on submission and do not have a verified USPTO.gov account, use an alternative filing method.

Migration will be available during this outage. Please ensure that you migrated the proper PKI to the correct USPTO.gov account. If you have not migrated or need to sponsor support staff, please visit the authentication change webpage for guidance.

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