724.04(c) Materials Submitted in Reexamination File Open to the Public Under 37 CFR 1.11(d)

Any materials submitted under MPEP § 724.02 in a reexamination file open to the public under 37 CFR 1.11(d) will be treated in the following manner:

(A) Materials submitted under MPEP § 724.02 will only be released to the public with any other papers in the reexamination file if no petition to expunge (37 CFR  1.59) was filed prior to the mailing of a Notice of Intent to Issue Reexamination Certificate (NIRC), or if a petition to expunge was filed and the petition was denied. The submitted information will be maintained separate from the reexamination file and will not be publicly available until a determination has been made as to whether or not the information is important to a reasonable examiner in deciding whether or not a claim is patentable.

(B) Prior to the mailing of a NIRC, the examiner will review the reexamination file and determine if a petition to expunge is in the reexamination file but not acted upon. The examiner, or other appropriate Office official who is responsible for considering the information, will make a determination as to whether or not any portion or all of the information submitted is important to a reasonable examiner in deciding whether or not a claim is patentable.

(C) If any portion or all of the submitted information is found important to a reasonable examiner in deciding whether or not a claim is patentable, the petition to expunge will be denied and the information will thereafter become a permanent part of the reexamination file and open to the public.

(D) If any portion or all of the submitted information is found not to be important to a reasonable examiner in deciding whether or not a claim is patentable, the petition to expunge will be granted and the information expunged.

(E) If a petition to expunge is not filed prior to the mailing of the NIRC, the materials submitted under MPEP § 724.02 will become a permanent part of the reexamination file and open to the public under 37 CFR  1.11(d).

(F) Any petition to expunge a portion or all of the submitted information under 37 CFR 1.59(b) will be treated in accordance with MPEP § 724.05.
