PKI Sign-In Discontinued as of Feb. 15
Written February 14, 2019
EFS-Web and Private PAIR users will no longer be able to authenticate using PKI certificates on February 15, 2019.
The USPTO has introduced a new login process which it advertises as “simpler and safer,” and is moving away from using PKI certificates for two-factor authentication because the software will no longer be supported. Users must migrate all PKIs before March 1.
New users, or users who do not migrate prior to March 1, must obtain a verified USPTO.gov account to access EFS-Web and PAIR using the website’s new verification process, which requires a notarized Patent Electronic System Verification Form. Prior to March 1, you can recover your PKI using your self-recovery codes.
