PKI authentication will be discontinued soon

Please use your verified USPTO.gov account to authenticate to EFS-Web and Private PAIR because the USPTO will discontinue use of Public Key Infrastructure (PKI) authentication soon. You will no longer be able sign in to EFS-Web or Private PAIR using a PKI certificate.  Please refer to the instructions below.

If your USPTO.gov account is already enabled to access EFS-Web and Private PAIR  

If you've already enabled your USPTO.gov account to access EFS-Web and Private PAIR, please use your USPTO.gov account to sign in.

 

If you have not yet migrated your PKI account

If you are a patent practitioner or independent inventor with an existing PKI certificate that has NOT been migrated, please use the Migration Tool to link your existing PKI certificate with your USPTO.gov account. The last day to migrate a PKI certificate to USPTO.gov account will be posted on the Authentication Change page.

For additional help:

If you have not been sponsored

If you are a support staff member (paralegals, legal admins, and others), previously using a Practitioner's PKI certificate, you must now have your own USPTO.gov account and be sponsored by a practitioner. Please request that the registered patent practitioner(s) whom you are supporting access the Sponsorship Tool to sponsor your USPTO.gov account to allow you to work on their behalf. In order to sponsor support staff, a practitioner must first migrate to a USPTO.gov account

If you are a new user

If you are a new patent practitioner or independent inventor, please see instructions to register for a new verified USPTO.gov account and the Patent Electronic System Access Document for information on the authentication, sponsorship, and verification for accessing the patent electronic system.
