Substantial New Question of Patentability Requires Ex Parte Reexamination
Note:
If a substantial new question of patentability is found, an ex parte reexamination must be ordered for resolution.

(a) If a substantial new question of patentability is found pursuant to § 1.515 or § 1.520, the determination will include an order for ex parte reexamination of the patent for resolution of the question. If the order for ex parte reexamination resulted from a petition pursuant to § 1.515(c), the ex parte reexamination will ordinarily be conducted by an examiner other than the examiner responsible for the initial determination under § 1.515(a).

Examiner Must Identify Substantial New Question of Patentability
Note:
The examiner must identify at least one substantial new question of patentability and explain how prior art raises it, indicating their initial position on all issues.

In the examiner’s decision, the examiner must identify at least one substantial new question of patentability and explain how the prior art patents and/or printed publications raise such a question. The examiner should indicate, insofar as possible, their initial position on all the issues identified in the request or by the requester (without rejecting claims) so that comment thereon may be received in the patent owner’s statement and in the requester’s reply. The prior art relied on should be listed on a form PTO-892 if it is not already listed on a form PTO/SB/08 or PTO/SB/42 (or on a form having a format equivalent to one of these forms) by the requester. A copy of a reference should be supplied only where it has not been previously supplied to the patent owner and requester.

Substantial New Question of Patentability Must Be Addressed
Note:
The decision must identify and address each substantial new question of patentability, including the prior art, new teaching, claims affected, and why it was not previously considered.
As to each substantial new question of patentability identified in the decision, the decision should point out:
  • (A) The prior art patents and printed publications which add some new teaching as to at least one claim;
  • (B) What that new teaching is;
  • (C) The claims that the new teaching is directed to;
  • (D) That the new teaching was not previously considered nor addressed in the earlier concluded examination or review of the patent or a final holding of invalidity by a federal court, and was not raised to or by the Office in a pending reexamination or supplemental examination of the patent;
  • (E) That the new teaching is such that a reasonable examiner would consider the new teaching to be important in deciding to allow the claim being considered; and
  • (F) Where the question is raised, or where it is not clear that a patent or printed publication pre-dates the patent claims, a discussion should be provided as to why the patent or printed publication is deemed to be available against the patent claims.

Substantial New Question of Patentability Must Be Raised
Note:
The decision on a request should indicate that a substantial new question of patentability is raised by the art, rather than stating that claims are unpatentable over specific prior art references.

The example in MPEP § 2247.01 is drafted for the case where the “request indicates that Requester considers that Claims 1-3 are unpatentable over Smith taken with Jones.” There may, however, be a request that does not indicate the claims to be unpatentable over the art, but rather that a substantial new question of patentability is raised by the art. This may occur, for example, in a patent owner request filed to address prior art that raises a substantial new question of patentability but the claims are still patentable over the art. In such an instance, the decision on the request should not state that the “request indicates that Requester considers that Claims 1-3 are unpatentable over Smith taken with Jones.” Rather, it should state that the “request indicates that Requester considers that a substantial new question of patentability is raised as to Claims 1-3 based on Smith taken with Jones.”

Examiner Only Decides on Reexamination Request
Note:
The examiner decides if there is a substantial new question of patentability to grant the request for reexamination, but does not decide on the patentability of claims or reject them based on prior art.

In the decision on the request, the examiner will not decide, and no statement should be made as to, whether the claims are rejected over the patents and printed publications. The examiner does not decide the question of patentability of the claims in the decision on the request. The examiner only decides whether there is a substantial new question of patentability to grant the request to order reexamination.

Challenge to Examiner's SNQ Determination in Response
Note:
Patent owner can challenge the examiner’s determination that a reference raises a substantial new question by requesting reconsideration and presenting arguments in response to the Office action.

A patent owner may challenge the correctness of the decision to grant an order for ex parte reexamination under 35 U.S.C. 304 on the basis that there is no SNQ by requesting reconsideration of the examiner's SNQ determination in a patent owner’s statement under 37 CFR 1.530 discussing the SNQ raised in the reexamination order for the examiner's consideration. See 35 U.S.C. 304. When the examiner makes a rejection based in whole or in part on a reference (patent or printed publication) in an Office action, the patent owner may present a challenge to the examiner's SNQ determination by requesting reconsideration of the examiner's determination that the reference raises a SNQ and presenting appropriate arguments in the response to the Office action. See 37 CFR 1.111(b) (the patent owner's response to an Office action must point out the supposed errors in the examiner's action and must reply to every ground of objection and rejection in the Office action). By presenting arguments regarding the SNQ to the examiner in the early stages of the proceeding, the patent owner helps the Office to resolve the issues quickly. For example, if the patent owner timely files a statement or response, and the examiner agrees with the patent owner that no SNQ has been raised in the ex parte reexamination proceeding, then the proceeding prosecution will be terminated or the reexamination order will be vacated (whichever is appropriate). However, if the examiner determines that the SNQ is proper, further review can be obtained by exhausting the patent owner's rights through the reexamination proceeding and ultimately seeking review before the Board – along with an appeal of any rejections. To obtain review of the SNQ issue, patent owner must include the SNQ issue and the appropriate arguments in its appeal brief to the Board.

Circumstances Allowing Vacating Reexamination Order
Note:
This rule outlines the situations where an order granting reexamination can be vacated, including when the reexamination is not based on prior art patents or printed publications, all claims are invalid by a court decision, the wrong patent was ordered for reexamination, or it was based on duplicate requests.
“Appropriate circumstances” under 37 CFR 1.181(a)(3) exist to vacate the order granting reexamination where, for example:
  • (A) the reexamination order under 35 U.S.C. 304 is facially not based on prior art patents or printed publications (this does not include a situation where the Office has given reasons why a reference is a prior art patent or printed publication, and patent owner disagrees, but rather would include, for example, a situation where reexamination is ordered based on 35 U.S.C. 112, with a reference used to support a new question as to 35 U.S.C. 112);
  • (B) all claims of the patent for which reexamination was ordered were held to be invalid by a final decision of a federal court after all appeals;
  • (C) reexamination was ordered for the wrong patent; or
  • (D) reexamination was ordered based on a duplicate copy of the request.

Patent Owner Must First Request Reconsideration Before Examiner for SNQ Review
Note:
A patent owner must first request reconsideration of the SNQ issue by the examiner before seeking Board review to preserve the right to have the Board review the SNQ issue.

In order to preserve the right to have the Board review the SNQ issue, a patent owner must have first requested reconsideration of the SNQ issue by the examiner. Accordingly, for ex parte reexamination proceedings ordered under 35 U.S.C. 304 on or after June 25, 2010, the patent owner may seek a final agency decision from the Board on the SNQ issue only if the patent owner has first requested reconsideration before the examiner (e.g., in a patent owner's statement under 37 CFR 1.530 or in a patent owner's response under 37 CFR 1.111) and then seeks review of the examiner's SNQ determination before the Board. In its appeal brief, the patent owner is to clearly present the issue and arguments regarding the examiner's SNQ determination under a separate heading and identify the communication in which the patent owner first requested reconsideration before the examiner. (For ex parte reexamination proceedings ordered under 35 U.S.C. 304 prior to June 25, 2010, if the patent owner presents the SNQ issue in its appeal brief, the Board panel will review the procedural SNQ issue along with its review of any rejections in an appeal and will enter a final agency decision accordingly.) See MPEP § 2274 for further discussion of the appeal process as to the SNQ issue.

Accordingly, for ex parte reexamination proceedings ordered under 35 U.S.C. 304 on or after June 25, 2010, the patent owner may seek a final agency decision from the Board on the SNQ issue only if the patent owner has first requested reconsideration before the examiner (e.g., in a patent owner's statement under 37 CFR 1.530 or in a patent owner's response under 37 CFR 1.111) and then seeks review of the examiner's SNQ determination before the Board. In its appeal brief, the patent owner is to clearly present the issue and arguments regarding the examiner's SNQ determination under a separate heading and identify the communication in which the patent owner first requested reconsideration before the examiner. (For ex parte reexamination proceedings ordered under 35 U.S.C. 304 prior to June 25, 2010, if the patent owner presents the SNQ issue in its appeal brief, the Board panel will review the procedural SNQ issue along with its review of any rejections in an appeal and will enter a final agency decision accordingly.)

The Director must order reexamination if a substantial new question of patentability is found affecting any claim of a patent, and the patent owner has a reasonable period to file a statement or amendment.

If, in a determination made under the provisions of subsection 303(a), the Director finds that a substantial new question of patentability affecting any claim of a patent is raised, the determination will include an order for reexamination of the patent for resolution of the question. The patent owner will be given a reasonable period, not less than two months from the date a copy of the determination is given or mailed to him, within which he may file a statement on such question, including any amendment to his patent and new claim or claims he may wish to propose, for consideration in the reexamination. If the patent owner files such a statement, he promptly will serve a copy of it on the person who has requested reexamination under the provisions of section 302. Within a period of two months from the date of service, that person may file and have considered in the reexamination a reply to any statement filed by the patent owner. That person promptly will serve on the patent owner a copy of any reply filed.

Prior Art Must Be Listed on PTO-892
Note:
The examiner must list prior art relied upon on a form PTO-892 if not already listed on forms PTO/SB/08 or PTO/SB/42 by the requester.

In the examiner’s decision, the examiner must identify at least one substantial new question of patentability and explain how the prior art patents and/or printed publications raise such a question. The examiner should indicate, insofar as possible, their initial position on all the issues identified in the request or by the requester (without rejecting claims) so that comment thereon may be received in the patent owner’s statement and in the requester’s reply. The prior art relied on should be listed on a form PTO-892 if it is not already listed on a form PTO/SB/08 or PTO/SB/42 (or on a form having a format equivalent to one of these forms) by the requester. A copy of a reference should be supplied only where it has not been previously supplied to the patent owner and requester.

Examiner Prepares Decision and First Action on Merits
Note:
The examiner prepares the decision on reexamination and, if applicable, the first action on merits either before or after a conference with the patent owner.

After the examiner receives the new reexamination file, the examiner will prepare for and set up a panel review conference as per MPEP § 2271.01, to discuss the issuance of a decision on the request for reexamination. The examiner may prepare the decision on the request for reexamination, and, where applicable, (where the statement has been waived by patent owner – see MPEP § 2249 “Waiver of Statement Program”) the first Office action to accompany the decision after the conference, or may prepare the decision on the request for reexamination, and, where applicable, the first Office action prior to the conference and revise it as needed after the conference.

Copy of PTOL-465 Attached to Office Actions
Note:
Whenever an Office action is issued, a copy of the PTOL-465 form must be attached to it for mailing third-party requesters.

If the conference confirms the examiner’s preliminary decision to grant reexamination, the decision on the request for reexamination will be completed and signed by the examiner, with the two or more other conferees initialing the action (as “conferee”) to indicate their presence in the conference. When ready, the examiner’s decision will be processed and mailed. A transmittal form PTOL-465 with the third-party requester’s address will be completed, if a copy for mailing is not already available. The transmittal form PTOL-465 is used to forward copies of Office actions (and any references cited in the actions) to the third-party requester. Whenever an Office action is issued, a copy of this form will be made and attached to a copy of the Office action. The use of this form removes the need to retype the third-party requester’s address each time a mailing is required. In conjunction with the mailing, any appropriate processing (e.g., content entry through the Patent Data Portal, update scanning) is carried out by the staff of the CRU.

Patent Owner Must Present SNQ Arguments Early
Note:
The patent owner must present arguments regarding the SNQ to the examiner early in the proceeding to help resolve issues quickly.

A patent owner may challenge the correctness of the decision to grant an order for ex parte reexamination under 35 U.S.C. 304 on the basis that there is no SNQ by requesting reconsideration of the examiner's SNQ determination in a patent owner’s statement under 37 CFR 1.530 discussing the SNQ raised in the reexamination order for the examiner's consideration. See 35 U.S.C. 304. When the examiner makes a rejection based in whole or in part on a reference (patent or printed publication) in an Office action, the patent owner may present a challenge to the examiner's SNQ determination by requesting reconsideration of the examiner's determination that the reference raises a SNQ and presenting appropriate arguments in the response to the Office action. See 37 CFR 1.111(b) (the patent owner's response to an Office action must point out the supposed errors in the examiner's action and must reply to every ground of objection and rejection in the Office action). By presenting arguments regarding the SNQ to the examiner in the early stages of the proceeding, the patent owner helps the Office to resolve the issues quickly. For example, if the patent owner timely files a statement or response, and the examiner agrees with the patent owner that no SNQ has been raised in the ex parte reexamination proceeding, then the proceeding prosecution will be terminated or the reexamination order will be vacated (whichever is appropriate). However, if the examiner determines that the SNQ is proper, further review can be obtained by exhausting the patent owner's rights through the reexamination proceeding and ultimately seeking review before the Board – along with an appeal of any rejections. To obtain review of the SNQ issue, patent owner must include the SNQ issue and the appropriate arguments in its appeal brief to the Board.

Examiner Form Paragraphs

Examiner form paragraphs are standard language that you might see in an Office Action or communication from the USPTO. Examiners have latitude to change the form paragraphs, but you will often see this exact language.

¶ 22.01 ¶ 22.01 New Question of Patentability

A substantial new question of patentability affecting claim [1] of United States Patent Number [2 ] is raised by the request for ex parte reexamination.

Extensions of time under 37 CFR 1.136(a) will not be permitted in these proceedings because the provisions of 37 CFR 1.136 apply only to “an applicant” and not to parties in a reexamination proceeding. Additionally, 35 U.S.C. 305 requires that ex parte reexamination proceedings “will be conducted with special dispatch” ( 37 CFR 1.550(a) ). Extensions of time in ex parte reexamination proceedings are provided for in 37 CFR 1.550(c) .

¶ 22.73 ¶ 22.73 Correspondence and Inquiry as to Office Actions

All correspondence relating to this ex parte reexamination proceeding should be directed:
