Authentication Change for EFS-Web and Private PAIR

EFS-Web and Private PAIR users now have a new, safer, and simpler login. The USPTO is moving from using PKI certificates for two-factor authentication because the PKI software vendor will no longer support the authentication software product after the end of 2018. With this in mind, the USPTO now offers users better security with the new, two-factor authentication method using accounts. The new method grants access to multiple USPTO systems with one consolidated sign-in and eliminates shared credentials by providing practitioners and their support staff with their own accounts.

The Migration Tool is available for existing PKI digital certificate holders (registered practitioners and independent inventors) to link their accounts to their current PKI digital certificates. To successfully migrate, users must already have a account. If you do not already have one, create a account and opt-in for two-step authentication. Please follow the step-by-step instructions to migrate and allow 1–2 business days after you finish the migration steps for the process to complete; you can then use your account to sign in to EFS-Web and Private PAIR. Customer Numbers associated with the PKI certificate will be migrated to the linked account. PKI certificates can still be used to sign in to EFS-Web and Private PAIR as well.

The Sponsorship Tool is now available for existing registered practitioners to sponsor their support staff to work on their behalf. The support staff individual must have already created a account and set it to two-step authentication in order to be sponsored by a practitioner. Please follow the step-by-step instructions to sponsor support staff. Once support staff are successfully sponsored, they will be able to sign in using their own account and select the registered practitioner that they are working on behalf of. Please review the Patent Electronic System Access Document for additional information on authentication, sponsorship, and verification for accessing patent electronic systems.
