Panel Review Conference Not Held for Allowed Claims
Note:
A panel review conference is not required for claims that were in the case and before the Board at the time of appeal decision.

A panel review conference is not to be held as to any claim that was in the case (proceeding) at the time the case was reviewed by the Board or a federal court. The following example will serve to illustrate this point. In a reexamination proceeding, claims 5-10 are allowed by the examiner, and claims 1-4 are rejected. The rejection of claims 1-4 is then appealed to the Board. The Board reverses the rejection of claims 1-4 and imposes a new ground of rejection of claims 1-4 under 37 CFR 41.50(b). The patent owner then elects further prosecution before the examiner pursuant to 37 CFR 41.50(b)(1) and submits an amended set of claims 1-4. The examiner finds amended claims 1-4 to be allowable and wishes to “allow” the entire case by issuing a NIRC. A panel review conference must be held at this stage of the proceeding. The conferees will review the allowance of amended claims 1-4. The conferees will not, however, review the allowance of claims 5-10, because claims 5-10 were in the case, and before the Board at the time the Board decided the appeal.

Amendments Not Allowed After Termination
Note:
No amendments, information disclosure statements, or other papers related to the merits can be filed after reexamination prosecution is terminated without a petition.

A NIRC informs the patent owner and any third party requester that the reexamination prosecution has been terminated. The rules do not provide for an amendment to be filed in a reexamination proceeding after prosecution has been terminated. The provisions of 37 CFR 1.312 do not apply in reexamination. Any amendment, information disclosure statement, or other paper related to the merits of the reexamination proceeding filed after prosecution has been terminated must be accompanied by a petition under 37 CFR 1.182 to have the amendment, information disclosure statement, or other paper considered.

No Panel Review Conference for Claim Cancellation
Note:
Examiner will issue a NIRC action with an examiner’s amendment canceling all live claims, without holding a panel review conference.

A panel review conference is not to be held, because the proceeding is to be concluded by the cancellation of all claims. Rather, the examiner will issue a NIRC action, and as an attachment to the NIRC, the examiner will draft an examiner’s amendment canceling all live claims in the reexamination proceeding. In the examiner’s amendment, the examiner should point out why the claims have been canceled. For example, the examiner might make one of the two following statements, as appropriate:

Examiner’s Amendments Not Subject to 1.121(g) in Reexamination
Note:
Examiner’s amendments in reexamination proceedings do not qualify for the exception set forth in 37 CFR 1.121(g).

Where it is necessary to amend the patent in order to place the proceeding in condition to issuance of a reexamination certificate, the examiner may request that the patent owner provide the amendment(s), or the examiner may make the amendments, with the patent owner’s approval, by an examiner’s amendment. If the changes are made by an examiner’s amendment, the examiner’s amendment must comply with the requirements of 37 CFR 1.530(d) – (j) in amending the patent.

Exception to Full Text Presentation Requirement for Claim Deletions
Note:
Allows deletion of an entire claim without presenting the full text if approved by the patent owner.

Where it is necessary to amend the patent in order to place the proceeding in condition to issuance of a reexamination certificate, the examiner may request that the patent owner provide the amendment(s), or the examiner may make the amendments, with the patent owner’s approval, by an examiner’s amendment. If the changes are made by an examiner’s amendment, the examiner’s amendment must comply with the requirements of 37 CFR 1.530(d) – (j) in amending the patent. Thus, the examiner’s amendment requires presentation of the full text of any paragraph or claim to be changed, with the 37 CFR 1.530(f) markings.

Title and Abstract Unchanged During Reexamination
Note:
The title of the invention and abstract should not be changed during reexamination unless necessary, in which case patent owner must be notified early. Examiner may only change them with owner's permission if all claims are found patentable.

Normally the title of the invention or the abstract will not need to be changed during reexamination. If a change to the title or to the abstract is necessary, the patent owner should be notified of the need to provide an amendment changing the title or abstract as early as possible in the prosecution as a part of an Office action. If all of the claims are found to be patentable and a NIRC has been or is to be mailed, the examiner may only change the title of the invention or the text of the abstract by an examiner’s amendment authorized by the patent owner. Changing the title and merely initialing the change is not permitted in reexamination.

Note:
A NIRC must be issued and signed by the examiner, with conferees initialing it to indicate their participation if the conference confirms the examiner's decision.

The examiner will so inform the examiner's Central Reexamination Unit (CRU) Supervisory Patent Reexamination Specialist (SPRS) or Technology Center (TC) Quality Assurance Specialist (QAS) of the conclusion of the reexamination proceeding. The CRU SPRS/TC QAS will convene a panel review conference (see MPEP § 2271.01), and the conference members will review the patentability of the claim(s). If the conference confirms the examiner’s decision, a NIRC shall be issued and signed by the examiner, with the two, or more, other conferees initialing the NIRC (as “conferee”) to indicate their participation in the conference. All conferees will initial, even though one of them may have dissented from the conference decision on the patentability of the claim(s).

NIRC Required for Allowable Claims
Note:
A Notice of Intent to Issue a Reexamination Certificate is required when claims are found allowable after appeal and further prosecution.

A panel review conference is not to be held as to any claim that was in the case (proceeding) at the time the case was reviewed by the Board or a federal court. The following example will serve to illustrate this point. In a reexamination proceeding, claims 5-10 are allowed by the examiner, and claims 1-4 are rejected. The rejection of claims 1-4 is then appealed to the Board. The Board reverses the rejection of claims 1-4 and imposes a new ground of rejection of claims 1-4 under 37 CFR 41.50(b). The patent owner then elects further prosecution before the examiner pursuant to 37 CFR 41.50(b)(1) and submits an amended set of claims 1-4. The examiner finds amended claims 1-4 to be allowable and wishes to “allow” the entire case by issuing a NIRC. A panel review conference must be held at this stage of the proceeding. The conferees will review the allowance of amended claims 1-4. The conferees will not, however, review the allowance of claims 5-10, because claims 5-10 were in the case, and before the Board at the time the Board decided the appeal.

Thus, a panel review conference must be held in each instance where a NIRC is about to be issued, unless the NIRC is being issued: (A) following and consistent with a decision by the Board (or court) on the merits of the proceeding; or (B) as a consequence of the patent owner’s failure to respond or take other action where such a response or action is necessary to maintain pendency of the proceeding and, as a result of which failure to respond, all of the claims will be canceled.

Notice of Intent to Issue Reexamination Certificate Terminates Prosecution
Note:
A Notice of Intent to Issue a Reexamination Certificate informs the patent owner and any third party that reexamination prosecution has ended, and no further amendments can be filed without a petition.

A NIRC informs the patent owner and any third party requester that the reexamination prosecution has been terminated. The rules do not provide for an amendment to be filed in a reexamination proceeding after prosecution has been terminated. The provisions of 37 CFR 1.312 do not apply in reexamination. Any amendment, information disclosure statement, or other paper related to the merits of the reexamination proceeding filed after prosecution has been terminated must be accompanied by a petition under 37 CFR 1.182 to have the amendment, information disclosure statement, or other paper considered.

Note:
The examiner must contact the patent owner by telephone to confirm that any timely response or appeal was not misdirected within the Office before issuing a Notice of Intent to Issue Reexamination Certificate.

Prior to canceling the claims and issuing the NIRC, the examiner should telephone the patent owner to inquire if a timely response, timely appeal, etc., was filed with the Office so as to make certain that a timely response has not been misdirected within the Office. If communication could not be made via telephone, the examiner could also use email (if authorized by the patent owner) to contact the patent owner.

Note:
The examiner will issue a NIRC action with an examiner’s amendment to cancel all live claims in the reexamination proceeding.

A panel review conference is not to be held, because the proceeding is to be concluded by the cancellation of all claims. Rather, the examiner will issue a NIRC action, and as an attachment to the NIRC, the examiner will draft an examiner’s amendment canceling all live claims in the reexamination proceeding. In the examiner’s amendment, the examiner should point out why the claims have been canceled. For example, the examiner might make one of the two following statements, as appropriate:

Requirements for NIRC Submission Before Processing
Note:
Examiner must ensure all patent claims, descriptions, and amendments are correctly completed and follow specific procedures before forwarding the NIRC.
The following items deserve special attention. The examiner should ensure they have been correctly completed or followed before forwarding for processing of the NIRC.
  • (A) All patent claims for which a substantial new question of patentability has been found must have been examined. See MPEP § 2243.
  • (B) No renumbering of patent claims is permitted. New claims may require renumbering. See MPEP § 2250.
  • (C) All amendments to the description and claims must conform to requirements of 37 CFR 1.530(d)-(j). This includes any changes made by Examiner’s Amendment. If a portion of the text is amended more than once, each amendment should indicate all of the changes (insertions and deletions) in relation to the current text in the patent under reexamination. See MPEP § 2250.
  • (D) The prior art must be listed on a form PTO 892, PTO/SB/08, or PTO/SB/42 (or on a form having a format equivalent to one of these forms). These forms must be properly completed. See MPEP § 2257.
  • (E) The examiner and reexamination clerk checklists PTO-1516 and PTO-1517 must be entirely and properly completed. A careful reading of the instructions contained in these checklists is essential. The clerical checklist is designed as a check and review of the examiner’s responses on the examiner checklist. Accordingly, the CRU support staff should personally review the file before completing an item. The CRU support staff should check to make certain that the responses to all related items on both checklists are in agreement.
  • (F) Multiple pending reexamination proceedings are often merged. See MPEP § 2283.
  • (G) Where the reexamination proceeding is copending with an application for reissue of the patent being reexamined, the files must have been forwarded to the Office of Patent Legal Administration (OPLA) for a consideration of potential merger, with a decision (by a Senior Legal Advisor) on the question being present in the reexamination file. See MPEP § 2285.
  • (H) Reasons for patentability and/or confirmation are required for each claim found patentable. See below.
  • (I) There is no issue fee in reexamination. See MPEP § 2233.
  • (J) The patent claims may not be amended nor new claims added after expiration of the patent. See MPEP § 2250.
  • (K) Original drawings cannot be physically changed. “Amended” or “New” figures must be appropriately labeled as such and presented on new sheets in compliance with 37 CFR 1.84. See 37 CFR 1.530(d)(3) and MPEP § 2250.01.
  • (L) An amended or new claim may not enlarge the scope of the patent claims. See MPEP § 2250.
  • (M) If the patent has expired, all amendments to the patent claims and all claims added during the proceeding must be withdrawn. Further, all presently rejected and objected-to claims are canceled by examiner’s amendment. See MPEP § 2250, subsection III, Amendment after the Patent Has Expired.

Review Required for Reexamination Certificate
Note:
Examiners must review reexamination and patent files to ensure all parts are completed before publishing the certificate.
In preparing the reexamination file for publication of the certificate, the examiner must review the reexamination and patent files (IFW and paper files) to be sure that all the appropriate parts are completed. The review should include completion of the following items:
  • (A) The IFW file wrapper Search Notes form — The “SEARCHED” and the “SEARCH NOTES” boxes are to be filled in with the classes and subclasses that were actually searched and other areas consulted. See MPEP § 719.05.
  • (B) The IFW file jacket form — Check to be sure that the necessary data is included thereon, such as the certificate number, e.g., “C1” or “C2”. The “Litigation Review” and “Copending Office Proceedings” boxes should be completed to ensure that the Office is aware of prior or concurrent litigation and Office proceedings.
  • (C) The Bibliographic Data Sheet — Check to be sure that the data included thereon is correct and the blank spaces have been initialed.
  • (D) The Issue Classification IFW form — The form must be completed to set forth the status of each claim and the final claim numbers. The appropriate information must be included in the “Issue Classification” boxes. The examiner should enter the classification in the Issue Classification boxes that corresponds to the current classification of the patent and any additional classification based on newly claimed subject matter. See MPEP § 903.07. The current classification of the patent may be found by viewing the patent in PE2E SEARCH, the automated search tool. See MPEP § 902.03(e). Completion of the Issue Classification boxes is required, even if all of the claims are canceled. An appropriate drawing figure is to be indicated for printing on the certificate cover sheet and in the Official Gazette. In addition, a representative claim which has been reexamined is to be indicated for publication in the Official Gazette. The claim or claims for the Official Gazette should be selected in accordance with the following instructions:
  • (A) The broadest claim should be selected;
  • (B) Examiners should ordinarily designate but one claim on each invention, although when a plurality of inventions are claimed in one application, additional claims up to a maximum of five may be designated for publication. In the case of reexamination, the examiner must select only one claim;
  • (C) A dependent claim should not be selected unless the independent claim from which it depends is also printed. In the case where a multiple dependent claim is selected, the entire chain of claims for one embodiment should be listed. In the case of reexamination, a dependent patent claim may be selected where the independent original patent claim has been canceled; in such a case, the dependent claim would be printed while the independent claim would not be printed; and
  • (D) In reissue applications, the broadest claim with changes or the broadest additional reissue claim should be selected for printing.

Examiner May Amend Patent for Reexamination Certificate
Note:
The examiner can request patent owner to provide amendments or make them with approval, ensuring the proceeding meets reexamination certificate issuance conditions.

Where it is necessary to amend the patent in order to place the proceeding in condition to issuance of a reexamination certificate, the examiner may request that the patent owner provide the amendment(s), or the examiner may make the amendments, with the patent owner’s approval, by an examiner’s amendment. If the changes are made by an examiner’s amendment, the examiner’s amendment must comply with the requirements of 37 CFR 1.530(d) – (j) in amending the patent. Thus, the examiner’s amendment requires presentation of the full text of any paragraph or claim to be changed, with the 37 CFR 1.530(f) markings. The exception for examiner’s amendments set forth in 37 CFR 1.121(g) does not apply to examiner’s amendments in reexamination proceedings. See MPEP § 2250. The only exception to the full text presentation requirement is that an entire claim or an entire paragraph of specification may be deleted from the patent by a statement deleting the claim or paragraph without the presentation of the text of the claim or paragraph.

Examiner Must Inspect Title Report
Note:
The examiner is required to review the title report in the file to ensure it matches the patent copy and address any discrepancies by contacting the patent owner.

The examiner should inspect the title report, or patent abstract of title, in the file. If the title report, or patent abstract of title, indicates a title in the inventors, but the patent copy shows an assignment to an assignee, a telephone call can be made to the patent owner, and the patent owner can be asked to submit a statement under 37 CFR 3.73 indicating that title is in the assignee (i.e., it has not reverted back to the inventors). If communication could not be made via telephone, the examiner could also use email (if authorized by the patent owner) to contact the patent owner. See MPEP § 320.

Claims Rejected and Canceled
Note:
All live claims in the proceeding, including claims 1-5 and 6-8, have been rejected by the Board decision of 9/9/99 and canceled due to lack of timely appeal.

“Claims 1-5 and 6-8 (all live claims in the proceeding) were subject to rejection in the last Office action mailed 9/9/99. Patent owner failed to timely respond to that Office action. Accordingly claims 1-5 and 6-8 have been canceled. See 37 CFR 1.550(d) and MPEP § 2266.” “The rejection of claims 1-5 and 6-8 (all live claims in the proceeding) has been affirmed in the Board decision of 9/9/99, and no timely appeal to the court has been filed. Accordingly claims 1-5 and 6-8 have been canceled.”

Prohibiting Title Changes Without Amendment
Note:
Examiners are not permitted to change the title of an invention during reexamination without a patent owner's authorized amendment.

Normally the title of the invention or the abstract will not need to be changed during reexamination. If a change to the title or to the abstract is necessary, the patent owner should be notified of the need to provide an amendment changing the title or abstract as early as possible in the prosecution as a part of an Office action. If all of the claims are found to be patentable and a NIRC has been or is to be mailed, the examiner may only change the title of the invention or the text of the abstract by an examiner’s amendment authorized by the patent owner. Changing the title and merely initialing the change is not permitted in reexamination.
