See MPEP §§ 903.07 and 905 through 907 for notations to be applied on the Issue Classification sheet. The Office Action Correspondence System (OACS) automatically populates the Issue Classification sheet with the Cooperative Patent Classification symbols applied to a family of documents (continuations, divisionals, and/or foreign documents in the family). These symbols are based on the inventive concepts in the disclosure, rather than solely based on the claimed subject matter. As such, it is possible that an issue classification will include classification group/subgroup symbols that were not searched by the examiner.
In all reissue applications, the number of the original patent which is being reissued should be placed in the box provided therefor below the box for the applicant’s name.
