Due to recent technical issues, the PKI authentication and migration deadlines associated with the authentication change for
EFS-Web and Private PAIR are no longer applicable until further notice.
Currently, authentication using both USPTO.gov accounts and PKI
certificates continues to be operational. We encourage you to use your
USPTO.gov accounts to authenticate in preparation for the upcoming
changes.
At
this time, most users have successfully migrated and are using their
USPTO.gov accounts to access EFS-Web and Private PAIR. If you have not
done so, please create your USPTO.gov account, ensure it is opted in to two-step authentication, and use the Migration Tool to link your existing PKI certificate to your USPTO.gov account. Registered practitioners should use the Sponsorship Tool to sponsor their support staff to work on their behalf.
More information regarding updated deadlines is forthcoming.
