1306.03 Practice After Payment of Issue Fee; Receipt of Issue Notification [R-5]
Under the current publication process, utility and reissue patents are issued within about four weeks after the issue fee and any required publication fee are received in the Office. A patent number and issue date will be assigned to an application and an Issue Notification will be mailed after the issue fee has been paid and processed by the USPTO. Because the Issue Notification may be mailed less than two weeks before the application is expected to issue as a patent, applicants are advised to file any continuing application before receiving the Issue Notification to avoid loss of copendency.
