How are incorrect papers handled in the patent file wrapper?
This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.
When a paper is incorrectly placed in the patent file wrapper, the USPTO has specific procedures to handle it while maintaining the integrity of the record. According to MPEP 724.01: ‘If a paper is placed in the file by applicant which discloses proprietary material, it may be returned to the applicant for submission under 37 CFR 1.59 but the Office will retain a copy of the paper.’ This approach ensures that while incorrect or proprietary papers can be addressed, a complete record is still maintained. The examiner or other USPTO personnel will typically make a note in the file indicating the reason for returning the paper and retaining a copy.
