609.02(c) Processing Requests to Change the Correspondence Address Before Registration
Once the correspondence address is established for a particular application, the USPTO will generally not change it unless there is a written request to do so, signed by the applicant or the qualified practitioner of record. 37 C.F.R. §§2.18(a)(7) and (b)(2). The mere transmittal of a response to an Office action bearing a new address for an applicant or an applicant’s qualified practitioner does not effect a change in a correspondence address. See TMEP §609.02(b) for further information about the requirements for a written request to change the correspondence address, and TMEP §609.02(a) for discussion of situations in which a request to change the correspondence address is presumed.
When the request is filed through TEAS, the data from the form is inputted directly into the USPTO's Trademark database. When a request to change the correspondence address is filed on paper, the USPTO manually enters the new correspondence address into its Trademark database and places the request in the application record, but does not send a confirmation or other acknowledgment of the request to change the correspondence address. The applicant may check the TSDR database at http://tsdr.uspto.gov to determine whether the change of address has been entered into the USPTO’s Trademark database.
The USPTO will not process a request to change the correspondence address in an abandoned application, unless submitted in conjunction with a petition to revive or request for reinstatement. When an applicant files a request to change the correspondence address in an abandoned application, the USPTO simply places the request in the record.
