2658 Scope of - 2600 Optional Inter Partes Reexamination
2658 Scope of Inter Partes Reexamination [Added R-2]
37 CFR 1.906 Scope of reexamination in inter partes reexamination proceeding.
(a) Claims in an inter partes reexamination proceeding will be examined on the basis of patents or printed publications and, with respect to subject matter added or deleted in the reexamination proceeding, on the basis of the requirements of 35 U.S.C. 112.
(b) Claims in an inter partes reexamination proceeding will not be permitted to enlarge the scope of the claims of the patent.
(c) Issues other than those indicated in paragraphs (a) and (b) of this section will not be resolved in an inter partes reexamination proceeding. If such issues are raised by the patent owner or the third party requester during a reexamination proceeding, the existence of such issues will be noted by the examiner in the next Office action, in which case the patent owner may desire to consider the advisability of filing a reissue application to have such issues considered and resolved.
Inter partes reexamination differs from ex parte reexamination in matters of procedure, such as when the third party requester can participate, the types of Office actions and the timing of issuance of the Office actions, and the requirement for identification of the real party in interest. Inter partes reexamination also differs from ex parte reexamination in the estoppel effect it provides as to the third party requesters and when the initiation of a reexamination is prohibited.
Inter partes reexamination does not, however, differ from ex parte reexamination as to the substance to be considered in the proceeding.
I. PRIOR ART PATENTS OR PRINTED PUBLICATIONS
Rejections on art in reexamination proceedings may only be made on the basis of prior art patents or printed publications. See MPEP § 2258 and § 2258.01 for a discussion of art rejections in reexamination proceedings based on prior art patents or printed publications. The discussion there includes making double patenting rejections and the use of admissions.
It is to be noted that the decisions cited in MPEP §§ 2258 and 2258.01 for determining the presence or absence of "a substantial new question of patentability" in ex parte reexamination proceedings apply equally in inter partes reexamination proceedings, since the statutory language relied upon in those decisions, which is taken from the ex parte reexamination statute, is also found in the inter partes reexamination statute.
II. COMPLIANCE WITH 35 U.S.C. 112
Where new or amended claims are presented or where any part of the disclosure is amended, the claims of the reexamination proceeding are to be examined for compliance with 35 U.S.C. 112. See MPEP § 2258 for a discussion of the examination in a reexamination proceeding based upon 35 U.S.C. 112.
III. CLAIMS IN PROCEEDING MUST NOT ENLARGE SCOPE OF THE CLAIMS OF THE PATENT
Where new claims are presented, or where any part of the disclosure is amended, the claims of the inter partes reexamination proceeding should be examined under 35 U.S.C. 314, to determine whether they enlarge the scope of the original claims. 35 U.S.C. 314(a) states that "no proposed amended or new claim enlarging the scope of the claims of the patent shall be permitted" in an inter partes reexamination proceeding.
A. Criteria for Enlargement of the Scope of the Claims
A claim presented in a reexamination proceeding enlarges the scope of the claims of the patent being reexamined where the claim is broader than each and every claim of the patent. See MPEP § 1412.03 for guidance as to when the presented claim is considered to be a broadening claim as compared with the claims of the patent, i.e., what is broadening and what is not. If a claim is considered to be a broadening claim for purposes of reissue, it is likewise considered to be a broadening claim in reexamination.
B. Amendment of the Specification
Where the specification is amended in a reexamination proceeding, the examiner should make certain that the amendment to the specification does not enlarge the scope of the claims of the patent. An amendment to the specification can enlarge the scope of the claims by redefining the scope of the terms in a claim, even where the claims are not amended in any respect.
C. Rejection of Claims Where There Is Enlargement
Any claim which enlarges the scope of the claims of the patent should be rejected under 35 U.S.C. 314(a). Form paragraph 26.03.01 is to be employed in making the rejection.
¶ 26.03.01 Rejection, 35 U.S.C. 314(a), Claim Enlarges Scope of Patent
Claim [1] rejected under 35 U.S.C. 314(a) as enlarging the scope of the claims of the patent being reexamined. 35 U.S.C. 314(a) states that "no proposed amended or new claim enlarging the scope of the claims of the patent shall be permitted" in an inter partes reexamination proceeding. A claim presented in a reexamination "enlarges the scope" of the patent claims where the claim is broader than the claims of the patent. A claim is broadened if it is broader in any one respect, even though it may be narrower in other respects. [2].
Examiner Note
The claim limitations which are considered to broaden the scope should be identified and explained in bracket 2. See MPEP § 2658.IV. OTHER MATTERS
A. Patent Under Reexamination Subject of a Prior Office or Court Decision
Where some of the patent claims in a patent being reexamined have been the subject of a prior Office or court decision, see MPEP § 2642. Where other proceedings involving the patent are copending with the reexamination proceeding, see MPEP § 2686 - § 2686.04.
Patent claims not subject to reexamination because of their prior adjudication by a court should be identified. See MPEP § 2642. For handling a "live" claim dependent on a patent claim not subject to reexamination, see MPEP § 2660.03. All added claims will be examined.
Where grounds set forth in a prior Office or Federal Court decision, are not based on patents or printed publications, yet clearly raise questions as to the claims, the examiner's Office action should clearly state that the claims have not been examined as to those grounds not based on patents or printed publications nor applicable portions of 35 U.S.C. 112 stated in the prior decision. See 37 CFR 1.906(c). See In re Knight, 217 USPQ 294 (Comm'r Pat. 1982). All claims under reexamination should, however, be reexamined on the basis of prior patents and printed publications.
B. All "Live" Claims Are Reexamined During Reexamination
Although a request for reexamination may not specify all claims as presenting a substantial new question, each "live" claim (i.e., each existing claim not held invalid by a final decision, after all appeals) of the patent will be reexamined. The resulting reexamination certificate will indicate the status of all of the patent claims and any added patentable claims.
C. Restriction Not Proper in Reexamination
Restriction requirements cannot be made in a reexamination proceeding since no statutory basis exists for restriction in a reexamination proceeding.
D. Ancillary Matters
There are matters ancillary to reexamination which are necessary and incident to patentability which will be considered. Amendments may be made to the specification to correct, for example, an inadvertent failure to claim foreign priority or the continuing status of the patent relative to a parent application if such correction is necessary to overcome a reference applied against a claim of the patent.
E. Claiming Foreign and Domestic Priority in Reexamination
The patent owner may obtain the right of foreign priority under 35 U.S.C. 119 (a)-(d) where a claim for priority had been made before the patent was granted, and it is only necessary for submission of the certified copy in the reexamination proceeding to perfect priority. Likewise, patent owner may obtain the right of foreign priority under 35 U.S.C. 119 (a)-(d) where it is necessary to submit for the first time both the claim for priority and the certified copy. However, where it is necessary to submit for the first time both the claim for priority and the certified copy, and the patent to be reexamined matured from a utility or plant application filed on or after November 29, 2000, then the patent owner will have to also file a grantable petition for an unintentionally delayed priority claim under 37 CFR 1.55(c). See MPEP § 201.14(a).
Also, patent owner may correct the failure to adequately claim (in the application for the patent to be reexamined) benefit under 35 U.S.C. 120 of an earlier filed copending U.S. patent application. For a patent to be reexamined which matured from a utility or plant applications filed on or after November 29, 2000, the patent owner will have to file a petition for an unintentionally delayed benefit claim under 37 CFR 1.78(a)(3). See MPEP § 201.11.
For a patent to be reexamined which matured from a utility or plant application filed before November 29, 2000, the patent owner can correct via reexamination the failure to adequately claim benefit under 35 U.S.C. 119(e) of an earlier filed provisional application. Under no circumstances can a reexamination proceeding be employed to correct or add a benefit claim under 35 U.S.C. 119(e) for a patent matured from a utility or plant application filed on or after November 29, 2000.
No renewal of previously made claims for foreign priority under 35 U.S.C. 119 or domestic benefit under 35 U.S.C. 119(e) or 120, is necessary during reexamination.
F. Correction of Inventorship
Correction of inventorship may also be made during reexamination. See 37 CFR 1.324 and MPEP § 1481 for petition for correction of inventorship in a patent. If a petition filed under 37 CFR 1.324 is granted, a Certificate of Correction indicating the change of inventorship will not be issued, because the reexamination certificate that will ultimately issue will contain the appropriate change-of-inventorship information (i.e., the Certificate of Correction is in effect merged with the reexamination certificate).
G. Affidavits in Reexamination
Affidavits under 37 CFR 1.131 and 1.132 may be utilized in a reexamination proceeding. Note, however, that an affidavit under 37 CFR 1.131 may not be used to "swear back" of a reference patent if the reference patent is claiming the same invention as the patent undergoing reexamination. In such a situation, the patent owner may, if appropriate, seek to raise this issue via an affidavit under 37 CFR 1.130 (see MPEP § 718) or in an interference proceeding via an appropriate reissue application if such a reissue application may be filed (see MPEP § 1449.02).
H. Issues Not Considered in Reexamination
If questions other than those indicated above (for example, questions of patentability based on public use or on sale, fraud, abandonment under 35 U.S.C. 102(c), etc.) are raised by the third party requester or the patent owner during a reexamination proceeding, the existence of such questions will be noted by the examiner in the next Office action, in which case the patent owner may desire to consider the advisability of filing a reissue application to have such questions considered and resolved. Such questions could arise in a reexamination requester's 37 CFR 1.915 request or in 37 CFR 1.947 comments by the third party requester.
Note Form paragraph 26.03.
¶ 26.03 Issue Not Within Scope of Inter Partes Reexamination
It is noted that an issue not within the scope of reexamination proceedings has been raised. [1].The issue will not be considered in a reexamination proceeding. 37 CFR 1.906(c). While this issue is not within the scope of reexamination, the patentee is advised that it may be desirable to consider filing a reissue application provided that the patentee believes one or more claims to be partially or wholly inoperative or invalid.
Examiner Note
1. In bracket 1, identify the issues.
2. This paragraph may be used either when the patent owner or the third party requester raises issues such as (but not limited to) public use or on sale, fraud, or abandonment of the invention. Such issues should not be raised independently by the patent examiner.
If questions of patentability based on public use or on sale, fraud, abandonment under 35 U.S.C. 102(c), etc. are independently discovered by the examiner during a reexamination proceeding but were not raised by the third party requester or the patent owner, the existence of such questions will not be noted by the examiner in an Office action, because 37 CFR 1.906(c) is only directed to such questions "raised by the patent owner or the third party requester".
I. Request for Reexamination Filed on Patent after it Has Been Reissued
Where a request for reexamination is filed on a patent after it has been reissued, reexamination will be denied because the patent on which the request for reexamination is based has been surrendered. Should reexamination of the reissued patent be desired, a new request for reexamination including, and based on, the specification and claims of the reissue patent must be filed.
Any amendment made by the patent owner in the prosecution of the reexamination proceeding, should treat the changes made by the granted reissue patent as the text of the patent, and all bracketing and underlining made with respect to the patent as changed by the reissue.
Where the reissue patent issues after the filing of a request for reexamination, see MPEP § 2686.03.
