724.05    Petition To Expunge Information or Copy of Papers in Application File [R-07.2015]

I.    INFORMATION SUBMITTED UNDER MPEP § 724.02

A petition under 37 CFR 1.59(b) to expunge information submitted under MPEP § 724.02, or that should have been submitted under MPEP § 724.02 (as where proprietary information is submitted in an information disclosure statement but inadvertently not submitted in a sealed envelope as discussed in MPEP § 724.02) will be entertained only if the petition fee (37 CFR 1.17(g) ) is filed and the information has been found not to be material to patentability. If the information is found to be material to patentability, any petition to expunge the information will be denied. Any such petition to expunge information submitted under MPEP § 724.02 should be submitted at the time of filing the information under MPEP § 724.02 and directed to the Technology Center (TC) to which the application is assigned. Such petition must contain:

  • (A) a clear identification of the information to be expunged without disclosure of the details thereof;
  • (B) a clear statement that the information to be expunged is trade secret material, proprietary material, and/or subject to a protective order, and that the information has not been otherwise made public;
  • (C) a commitment on the part of the petitioner to retain such information for the period of enforceability of any patent with regard to which such information is submitted;
  • (D) a statement that the petition to expunge is being submitted by, or on behalf of, the party in interest who originally submitted the information;
  • (E) the fee as set forth in 37 CFR 1.17(g) for a petition under 37 CFR 1.59(b).

Any such petition to expunge should accompany the submission of the information and, in any event, must be submitted in sufficient time that it can be acted on prior to the mailing of a notice of allowability or a notice of abandonment for original and reissue applications, or prior to, or shortly after (i.e., in time to be addressed before the reexamination proceeding enters the reexamination certificate printing process), the mailing of a Notice of Intent to Issue Reexamination Certificate (NIRC) for reexamination proceedings. Timely submission of the petition is, accordingly, extremely important. If the petition does not accompany the information when it is initially submitted, the petition should be submitted while the application or reexamination is pending in the Technology Center (TC) and before it is transmitted to the Publishing Division. If a petition to expunge is not filed prior to the mailing of a notice of allowability or a notice of abandonment for original and reissue applications, or prior to, or shortly after (i.e., in time to be addressed before the reexamination proceeding enters the reexamination certificate printing process), the mailing of a NIRC for reexamination proceedings, any material then in the file will remain therein and be open to the public in accordance with 37 CFR 1.14. Accordingly, it is important that both the submission of any material under MPEP § 724.02 and the submission of any petition to expunge occur as early as possible during the examination process. The decision will be held in abeyance and be decided upon the close of prosecution on the merits.

II.    INFORMATION UNINTENTIONALLY SUBMITTED IN APPLICATION

A petition to expunge information unintentionally submitted in an application (other than information forming part of the original disclosure) may be filed under 37 CFR 1.59(b), provided that:

  • (A) the Office can effect such return prior to the issuance of any patent on the application in issue;
  • (B) it is stated that the information submitted was unintentionally submitted and the failure to obtain its return would cause irreparable harm to the party who submitted the information or to the party in interest on whose behalf the information was submitted;
  • (C) the information has not otherwise been made public;
  • (D) there is a commitment on the part of the petitioner to retain such information for the period of any patent with regard to which such information is submitted;
  • (E) it is established to the satisfaction of the Director that the information to be returned is not material information under 37 CFR 1.56; and
  • (F) the petition fee as set forth in 37 CFR 1.17(g) is included.

A request to expunge information that has not been clearly identified as information that may be later subject to such a request by marking and placement in a separate sealed envelope or container shall be treated on a case-by-case basis. Applicants should note that unidentified information that is a trade secret, proprietary, or subject to a protective order that is submitted in an Information Disclosure Statement may inadvertently be placed in an Office prior art search file by the examiner due to the lack of such identification and may not be retrievable.

III.    INFORMATION SUBMITTED IN INCORRECT APPLICATION

37 CFR 1.59(b) also covers the situation where an unintended heading has been placed on papers so that they are present in an incorrect application file. In such a situation, a petition should request that the papers be expunged rather than transferred to the correct application file. The grant of such a petition will be governed by the factors enumerated in paragraph II of this section in regard to the unintentional submission of information. Where the Office can determine the correct application file that the papers were actually intended for, based on identifying information in the heading of the papers (e.g., application number, filing date, title of invention and inventor(s) name(s)), the Office will transfer the papers to the correct application file for which they were intended without the need of a petition. However, if the papers are correctly matched with the application serial number given in an electronic filing via EFS-WEB, the information is not considered to have been submitted in the incorrect application even if the identifying information in the heading of the papers is directed toward a different application.

IV.    INFORMATION FORMING PART OF THE ORIGINAL DISCLOSURE

A petition to expunge a part of the original disclosure must be filed under 37 CFR 1.183, since such a request requires a waiver of the requirements of 37 CFR 1.59(a). Petitions under 37 CFR 1.183 should be directed to the Office of Petitions. The petition must explain why justice requires waiver of the rules to permit the requested material to be expunged. It should be noted that petitions to expunge information which is a part of the original disclosure, such as the specification and drawings, will ordinarily not be favorably entertained. The original disclosures of applications are scanned for record keeping purposes. Accordingly, the grant of a petition to expunge information which is part of the original disclosure would require that the USPTO record of the originally filed application be changed, which may not be possible.
