If after selecting the USPTO SSO button, the user experiences a problem with single sign-on, please ask them to contact the (USPTO) Service Desk.

If you are unable to log in after selecting the USPTO SSO button, please contact the (USPTO) Service Desk by phone at 2-9000 or by email servicedesk@uspto.gov and request help with the issue.

This is a technical issue with Single Sign-On, not a Learning Center issue.

Thank you.
