When a reissue application is filed, it goes through the normal prosecution process while the original patent that is the basis for the reissue also continues. Annuity fees must be maintained until the reissue is granted, at which time the original basis patent is surrendered and the IFI legal status is set to “Ceased”. Unlike a regular utility patent application, the reissue application is NOT published prior to grant. Furthermore, the reissue patent term is only for the remainder of the original patent term . No patent term adjustment is carried over to the reissue patent termwhich includes any extensions and adjustments at the time of issuance.
The reissue information in the original basis patent is found in the office-specific-data container. The reissue application information shows the new reissue application number and once the reissue grants, the reissue grant publication number is also available.
