To be sure the USPTO sends this letter to a current address, please check the official roster of registered patent attorneys and agents located at Patent Attorneys/Agents Search. If the contact information is correct, the practitioner need not update the information and the letter will be sent to that address. If the information is not current, the practitioner should go to Change of Address Form [PDF], complete the address change form, and promptly mail the change of address form to Mailstop OED, U.S. Patent and Trademark Office, P.O. Box 1450, Alexandria, Virginia 22313-1450. Practitioners who have been removed from the Roster of Patent Attorneys and Agents must apply for reinstatement to the roster.
