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
