human: How can I get patent information on submitting a change of correspondence address?
assistant: Where an attorney or agent of record (or applicant, if he or she is prosecuting the application pro se) changes his or her correspondence address, he or she is responsible for promptly notifying the United States Patent and Trademark Office of the new correspondence address (including ZIP code number). The notification should also include his or her telephone number. For additional information on change of correspondence address, you may visit the Patents page and then by clicking on ""Customer-requested actions"" see MPEP Chapter 601.03. Also, you may visit our web site for patent forms , see Form No. PTO/SB/122 (pending application) and PTO/SB/123 (issued patent).
In addition, an address represented by a Customer Number [definition] may be designated as the correspondence address of one or more applications (or patents) or the fee address of one or more allowed applications or patents. In addition, a Customer number representing a list of practitioners may be designated as the practitioners covered by a Power of Attorney in one or more applications or patents. A Customer Number associated with a correspondence address of an application or patent is the Customer Number used to obtain access to the Private Patent Application Information Retrieval (PAIR) system for that application or patent at http://portal.uspto.gov/external/portal/pair. See MPEP § 1730 for additional information regarding PAIR. To use Patent Center for change of correspondence address please see the Patent Center user guide.
