Examiner Must Provide Patent Owner with Useful Information Twice Before Final Action
Note:
The examiner must provide the patent owner with useful information and references twice before making a final action to define the Office's position on unpatentability.

Before a final action is in order, a clear issue should be developed between the examiner and the patent owner. To bring the prosecution to a speedy conclusion and at the same time deal justly with the patent owner and the public, the examiner will twice provide the patent owner with such information and references as may be useful in defining the position of the Office as to unpatentability before the action is made final. Initially, the decision ordering reexamination of the patent will contain an identification of the substantial new questions of patentability that the examiner considers to be raised by the cited prior art. In addition, the first Office action will reflect the consideration of any arguments contained in the request, any amendments submitted with a request under 35 U.S.C. 302, any owner’s statement filed pursuant to 37 CFR 1.530, and any reply thereto by the requester, and should fully apply all relevant grounds of rejection to the claims.

Second Office Action Generally Final In Reexamination
Note:
The second office action in a reexamination proceeding will typically be made final, similar to the criteria for making a rejection final in an application.

It is intended that the second Office action in the reexamination proceeding following the decision ordering reexamination will generally be made final. The criteria for making a rejection final in an ex parte reexamination proceeding is analogous to that set forth in MPEP § 706.07(a) for making a rejection final in an application. Both the patent owner and the examiner should recognize that a reexamination proceeding may result in the final cancellation of claims from the patent and that the patent owner does not have the right to renew or continue the proceedings by refiling under 37 CFR 1.53(b) or 37 CFR 1.53(d) or former 37 CFR 1.60 or 1.62, nor by filing a request for continued examination under 37 CFR 1.114. Complete and thorough actions by the examiner coupled with complete responses by the patent owner, including early presentation of evidence under 37 CFR 1.131(a) or 37 CFR 1.132, will go far in avoiding such problems and reaching a desirable early termination of the reexamination prosecution.

Reexamination Final Cancellation No Renewal
Note:
Patent owner cannot renew or continue reexamination by refiling under specific rules after claims may be cancelled.

It is intended that the second Office action in the reexamination proceeding following the decision ordering reexamination will generally be made final. The criteria for making a rejection final in an ex parte reexamination proceeding is analogous to that set forth in MPEP § 706.07(a) for making a rejection final in an application.

Clear Issue Must Be Developed Before Final Action
Note:
Before finalizing an action, the examiner must develop a clear issue with the patent owner based on prior art and any submitted arguments or amendments.

Before a final action is in order, a clear issue should be developed between the examiner and the patent owner. To bring the prosecution to a speedy conclusion and at the same time deal justly with the patent owner and the public, the examiner will twice provide the patent owner with such information and references as may be useful in defining the position of the Office as to unpatentability before the action is made final.

Review All Grounds of Rejection in Final Action
Note:
Ensure all grounds of rejection are carefully reviewed and clearly developed for the patent owner to assess an appeal.

In making the final rejection, all outstanding grounds of rejection of record should be carefully reviewed and any grounds or rejection relied on should be reiterated. The grounds of rejection must (in the final rejection) be clearly developed to such an extent that the patent owner may readily judge the advisability of an appeal. However, where a single previous Office action contains a complete statement of a ground of rejection, the final rejection may refer to such a statement and also should include a rebuttal of any arguments raised in the patent owner’s response.

Examiner May Use New Prior Art Without Amendment
Note:
If new prior art is submitted without a statement similar to 37 CFR 1.97(e), the examiner may use it and make the next Office action final, even if claims are not amended.

Where art is submitted in a prior art citation under 37 CFR 1.501 and/or 37 CFR 1.555 (an IDS filed in a reexamination is construed as a prior art citation) and the submission is not accompanied by a statement similar to that of 37 CFR 1.97(e), the examiner may use the art submitted and make the next Office action final whether or not the claims have been amended, provided that no other new ground of rejection is introduced by the examiner based on the new art not cited in the prior art citation.

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.

¶ 22.09 ¶ 22.09 Ex Parte Reexamination – Action Is Final

THIS ACTION IS MADE FINAL.

A shortened statutory period for response to this action is set to expire [1] from the mailing date of this action.

Extensions of time under 37 CFR 1.136(a) do not apply in reexamination proceedings. The provisions of 37 CFR 1.136 apply only to “an applicant” and not to parties in a reexamination proceeding. Further, in 35 U.S.C. 305 and in 37 CFR 1.550(a) , it is required that reexamination proceedings “will be conducted with special dispatch within the Office.”

Extensions of time in reexamination proceedings are provided for in 37 CFR 1.550(c) . A request for extension of time must specify the requested period of extension and it must be accompanied by the petition fee set forth in 37 CFR 1.17(g) . Any request for an extension in a third party requested ex parte reexamination must be filed on or before the day on which action by the patent owner is due, and the mere filing of a request will not effect any extension of time. A request for an extension of time in a third party requested ex parte reexamination will be granted only for sufficient cause, and for a reasonable time specified. Any request for extension in a patent owner requested ex parte reexamination (including reexamination ordered under 35 U.S.C. 257 ) for up to two months from the time period set in the Office action must be filed no later than two months from the expiration of the time period set in the Office action. A request for an extension in a patent owner requested ex parte reexamination for more than two months from the time period set in the Office action must be filed on or before the day on which action by the patent owner is due, and the mere filing of a request for an extension for more than two months will not effect the extension. The time for taking action in a patent owner requested ex parte reexamination will not be extended for more than two months from the time period set in the Office action in the absence of sufficient cause or for more than a reasonable time.

The filing of a timely first response to this final rejection will be construed as including a request to extend the shortened statutory period for an additional two months. In no event, however, will the statutory period for response expire later than SIX MONTHS from the mailing date of the final action. See MPEP § 2265 .

¶ 22.10 ¶ 22.10 Ex Parte Reexamination – Action Is Final, Necessitated by Amendment

Patent owner’s amendment filed [1] necessitated the new grounds of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL . See MPEP § 706.07(a) .

A shortened statutory period for response to this action is set to expire [2] from the mailing date of this action.

Extensions of time under 37 CFR 1.136(a) do not apply in reexamination proceedings. The provisions of 37 CFR 1.136 apply only to “an applicant” and not to parties in a reexamination proceeding. Further, in 35 U.S.C. 305 and in 37 CFR 1.550(a) , it is required that reexamination proceedings “will be conducted with special dispatch within the Office.”

Extensions of time in reexamination proceedings are provided for in 37 CFR 1.550(c) . A request for extension of time must specify the requested period of extension and it must be accompanied by the petition fee set forth in 37 CFR 1.17(g) . Any request for an extension in a third party requested ex parte reexamination must be filed on or before the day on which action by the patent owner is due, and the mere filing of a request will not effect any extension of time. A request for an extension of time in a third party requested ex parte reexamination will be granted only for sufficient cause, and for a reasonable time specified. Any request for extension in a patent owner requested ex parte reexamination (including reexamination ordered under 35 U.S.C. 257 ) for up to two months from the time period set in the Office action must be filed no later than two months from the expiration of the time period set in the Office action. A request for an extension in a patent owner requested ex parte reexamination for more than two months from the time period set in the Office action must be filed on or before the day on which action by the patent owner is due, and the mere filing of a request for an extension for more than two months will not effect the extension. The time for taking action in a patent owner requested ex parte reexamination will not be extended for more than two months from the time period set in the Office action in the absence of sufficient cause or for more than a reasonable time.

The filing of a timely first response to this final rejection will be construed as including a request to extend the shortened statutory period for an additional two months. In no event, however, will the statutory period for response expire later than SIX MONTHS from the mailing date of the final action. See MPEP § 2265 .
