Return of Inappropriate Papers Reduces Scanned Record
Note:
Papers deemed inappropriate are expunged from the record, reducing the amount of scanned documents.

The return of inappropriate submissions complies with the regulations that certain papers will not be considered and also reduces the amount of paper which would ultimately have to be scanned into the record. Where an inappropriate (unauthorized, improper) paper has already been scanned into the Image File Wrapper (IFW) of the reexamination proceeding before discovery of the inappropriate nature of the paper, the paper cannot be physically returned to the party that submitted it. Instead, the paper will be “returned” by expunging it, i.e., by marking the paper as “non-public” and “closed” so that it does not appear in the active IFW record with the other active papers that comprise the public record of the reexamination proceeding.

Any opposition to a petition must be filed within two weeks of receiving the original petition, otherwise it will remain in the record but not considered.

After a third party files an opposition, no further responses will be considered in inter partes reexamination.
