Patent Owner Submission Not Fully Responsive to Non-Final Office Action in Reexamination
Note:
The examiner may treat a patent owner's submission that is not fully responsive to a non-final Office action by waiving deficiencies, accepting the amendment with a new response requirement, or notifying completion within the remaining period to avoid proceeding termination.
Where patent owner’s amendment or response prior to final rejection is not fully responsive to an Office action in a reexamination and meets all of (A) through (C) above, the prosecution of the reexamination proceeding should not be terminated; but, rather, a practice similar to that of 37 CFR 1.135(c) (which is directed to applications) may be followed. The examiner may treat a patent owner submission which is not fully responsive to a non-final Office action by:
  • (A) waiving the deficiencies (if not serious) in the response and acting on the patent owner submission;
  • (B) accepting the amendment as a response to the non-final Office action but notifying the patent owner (via a new Office action setting a new time period for response) that the omission must be supplied; or
  • (C) notifying the patent owner that the response must be completed within the remaining period for response to the non-final Office action (or within any extension pursuant to 37 CFR 1.550(c)) to avoid termination of the prosecution of the proceeding under 37 CFR 1.550(d). This third alternative should only be used in the very unusual situation where there is sufficient time remaining in the period for response (including extensions under 37 CFR 1.550(c)), as is discussed below.

Patent Owner Submission Must Address All Rejections
Note:
A patent owner submission must address all rejections, objections, or requirements in a non-final Office action; otherwise, the examiner may issue a new Office action addressing unaddressed issues.

Where a patent owner submission responds to the rejections, objections, or requirements in a non-final Office action and is a bona fide attempt to advance the reexamination proceeding to final action, but contains a minor deficiency (e.g., fails to treat every rejection, objection, or requirement), the examiner may simply act on the amendment and issue a new (non-final or final) Office action. The new Office action may simply reiterate the rejection, objection, or requirement not addressed by the patent owner submission, or the action may indicate that such rejection, objection, or requirement is no longer applicable. In the new Office action, the examiner will identify the part of the previous Office action which was not responded to and make it clear what is needed. Obviously, this course of action would not be appropriate in instances in which a patent owner submission contains a serious deficiency (e.g., the patent owner submission does not appear to have been filed in response to the non-final Office action).

Omission After Final Rejection Must Not Be Noticed
Note:
If a response to an examiner's final rejection is filed with an omitted point, the examiner should not issue a failure notice but instead provide an advisory action explaining the omission.

The practice of giving the patent owner a time period to supply an omission in a bona fide response does not apply after a final Office action. If a bona fide response to an examiner’s action is filed after final rejection (before the expiration of the permissible response period), but through an apparent oversight or inadvertence, some point necessary to fully respond has been omitted, the examiner should not issue (to the patent owner) a notice of failure to fully respond. Rather, an advisory Office action (form PTOL-467) should be issued with an explanation of the omission. The time period set in the final rejection continues to run and is extended by two months if the response is the first response after the final rejection in accordance with the guidelines set forth in MPEP § 2265. See also MPEP § 2272.

Amendments Must Place Proceeding in Condition for Issuance of Certificate or Better Appeal Form
Note:
Amendments after final rejection are approved only if they place the proceeding in condition for a reexamination certificate or improve appeal form; otherwise, they are denied.

Amendments after final rejection are approved for entry only if they place the proceeding in condition for issuance of a reexamination certificate or in better form for appeal. Otherwise, they are not approved for entry. See MPEP § 714.12 and § 714.13. Thus, an amendment after final rejection should be denied entry if some point necessary for a complete response under 37 CFR 1.113 was omitted, even where the omission was through an apparent oversight or inadvertence. Where a submission after final Office action (e.g., an amendment filed under 37 CFR 1.116) does not place the proceeding in condition for issuance of a reexamination certificate, the period for response continues to run until a response under 37 CFR 1.113 (i.e., a notice of appeal or an amendment that places the proceeding in condition for issuance of a reexamination certificate) is filed. Where a submission after appeal (e.g., an amendment filed under 37 CFR 41.33) does not place the proceeding in condition for issuance of a reexamination certificate, the period for filing an appeal brief continues to run until an appeal brief or an amendment that places the proceeding in condition for issuance of a reexamination certificate is filed. The nature of the omission is immaterial. The examiner cannot give the patent owner a time period to supply the omission.

Note:
A patent owner submission must address all rejections, objections, or requirements in a non-final Office action; if it contains a serious deficiency, such as not responding to the action, it will be deemed inappropriate.

Where a patent owner submission responds to the rejections, objections, or requirements in a non-final Office action and is a bona fide attempt to advance the reexamination proceeding to final action, but contains a minor deficiency (e.g., fails to treat every rejection, objection, or requirement), the examiner may simply act on the amendment and issue a new (non-final or final) Office action.

Examiner May Grant New Time for Omission but Not if Abused
Note:
An examiner may give a patent owner an extended time period to address an omission, but should not do so if the patent owner is attempting to misuse this practice to gain additional response time.

This practice authorizes, but does not require, an examiner to give the patent owner a new time period to supply an omission. Thus, where the examiner concludes that the patent owner is attempting to abuse the practice to obtain additional time for filing a response, the practice should not be followed.

Where patent owner’s submission contains a serious deficiency (i.e., omission) to be dealt with prior to issuing an action on the merits and the period for response has expired, or there is insufficient time remaining to take corrective action before the expiration of the period for response, the patent owner should be notified of the deficiency and what is needed to correct the deficiency, and given a new time period for response.

If a third party requests reexamination, the examiner must insert 'ONE MONTH or thirty days, whichever is longer' for the examination timeframe.

2. In bracket 3, if the reexamination was requested by a third party requester, the examiner should insert “ONE MONTH or thirty days, whichever is longer”. If the reexamination was requested by the patent owner, if the reexamination was ordered under 35 U.S.C. 257, or if it is a Director-ordered reexamination, the examiner should insert “TWO MONTHS”.

Requirement for Inadvertent Omission Only
Note:
The rule requires that a time period to supply an omission is applicable only when the missing matter is considered inadvertently omitted by the examiner.

The practice of giving the patent owner a time period to supply an omission in a bona fide response (which is analogous to that set forth in 37 CFR 1.135(c) for an application) does not apply where there has been a deliberate omission of some necessary part of a complete response; rather, it is applicable only when the missing matter or lack of compliance is considered by the examiner as being “inadvertently omitted.” Once an inadvertent omission is brought to the attention of the patent owner, the question of inadvertence no longer exists. Therefore, a second Office action giving another new time period to supply the omission would not be appropriate. However, if patent owner’s response to the notification of the omission raises a different issue of a different inadvertently omitted matter, a second Office action may be given.

Period for Appeal Brief Continues Until Correct Submission
Note:
The period to file an appeal brief continues until a proper submission that places the proceeding in condition for issuance of a reexamination certificate is made.

Amendments after final rejection are approved for entry only if they place the proceeding in condition for issuance of a reexamination certificate or in better form for appeal. Otherwise, they are not approved for entry. See MPEP § 714.12 and § 714.13. Thus, an amendment after final rejection should be denied entry if some point necessary for a complete response under 37 CFR 1.113 was omitted, even where the omission was through an apparent oversight or inadvertence. Where a submission after final Office action (e.g., an amendment filed under 37 CFR 1.116) does not place the proceeding in condition for issuance of a reexamination certificate, the period for response continues to run until a response under 37 CFR 1.113 (i.e., a notice of appeal or an amendment that places the proceeding in condition for issuance of a reexamination certificate) is filed. Where a submission after appeal (e.g., an amendment filed under 37 CFR 41.33) does not place the proceeding in condition for issuance of a reexamination certificate, the period for filing an appeal brief continues to run until an appeal brief or an amendment that places the proceeding in condition for issuance of a reexamination certificate is filed. The nature of the omission is immaterial. The examiner cannot give the patent owner a time period to supply the omission.

Omission Through Oversight Requires Issuance of Reexamination Certificate
Note:
Where an amendment submitted after response time would place the proceeding in condition for a reexamination certificate except for an omission, the examiner should issue the certificate.

The examiner has the authority to enter the response, withdraw the final Office action, and issue a new Office action, which may be a final Office action, if appropriate, or an action in an otherwise allowable application under Ex parte Quayle, 25 USPQ 74, 1935 C.D. 11 (Comm’r Pat. 1935), if appropriate. This course of action is within the discretion of the examiner. However, the examiner should recognize that substantial patent rights will be at issue with no opportunity for the patent owner to refile under 37 CFR 1.53(b) or 1.53(d) in order to continue prosecution nor to file a request for continued examination under 37 CFR 1.114. Thus, where the time has expired for response and the amendment submitted would place the proceeding in condition for issuance of a reexamination certificate except for an omission through apparent oversight or inadvertence, the examiner should follow this course of action.

Patent Owner Submission Must Correct Deficiency
Note:
The patent owner must correct any serious deficiency in their submission before the response period expires to avoid prosecution termination.

Where patent owner’s submission contains a serious deficiency (i.e., omission) to be dealt with prior to issuing an action on the merits and the period for response has expired, or there is insufficient time remaining to take corrective action before the expiration of the period for response, the patent owner should be notified of the deficiency and what is needed to correct the deficiency, and given a new time period for response. The patent owner must supply the omission within the new time period for response (or any extensions under 37 CFR 1.550(c) thereof) to avoid termination of the prosecution of the proceeding under 37 CFR 1.550(d). The patent owner may also file a further response as permitted under 37 CFR 1.111. This is analogous to 37 CFR 1.135(c) for an application.

Where patent owner’s submission contains a serious deficiency (i.e., omission) to be dealt with prior to issuing an action on the merits and the period for response has expired, or there is insufficient time remaining to take corrective action before the expiration of the period for response, the patent owner should be notified of the deficiency and what is needed to correct the deficiency, and given a new time period for response.

Requirement for Full Response to Examiner's Action
Note:
A response must address all necessary points raised by the examiner and comply with any requirements made, otherwise it is considered not fully responsive.

A response by the patent owner will be considered not fully responsive to a non-final Office action where:

(C) but through an apparent oversight or inadvertence, some point necessary to a full response has been omitted (i.e., appropriate consideration of a matter that the action raised, or compliance with a requirement made by the examiner, has been omitted).

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.

¶ 22.14 ¶ 22.14 Submission Not Fully Responsive to Non-Final Office Action – Ex Parte Reexamination

The communication filed on [1] is not fully responsive to the prior Office action. [2] . The response appears to be bona fide , but through an apparent oversight or inadvertence, consideration of some matter or compliance with some requirement has been omitted. Patent owner is required to deal with the omission to thereby provide a full response to the prior Office action.

A shortened statutory period for response to this letter is set to expire [3] from the mailing date of this letter. If patent owner fails to timely deal with the omission and thereby provide a full response to the prior Office action, prosecution of the present reexamination proceeding will be terminated. 37 CFR 1.550(d) .
