Returned Paper Must Be Expunged From IFW
Note:
If an unauthorized paper is scanned into the Image File Wrapper before its nature is recognized, it must be expunged by marking it non-public and closed. No copy will be retained by the Office.

Where an unauthorized or otherwise improper paper has already been scanned into the Image File Wrapper (IFW) of the supplemental examination proceeding before recognizing the nature of the paper, the paper cannot be physically returned to the party that submitted it. Instead, the paper will be expunged, i.e., by marking the paper "non-public" and "closed" so it does not appear in the public record of the supplemental examination proceeding. A copy of the Office communication notifying the patent owner of the return of the paper (or its expungement) will be made of record in the patent file. However, no copy of the returned/expunged paper will be retained by the Office. If a later submission of the returned/expunged paper is appropriate, such as during any resulting ex parte reexamination proceeding, then the paper may be filed and entered by the Office at that time. The date of the later submission will be the filing date of the paper.

An unauthorized paper submitted to a supplemental examination proceeding must be marked non-public and closed, not physically returned, to ensure it does not appear in the public record.
