Director Must Determine Substantial New Question of Patentability Within Three Months
Note:
The Director must decide within three months if a new question about the patent's validity is raised by a reexamination request, considering any relevant patents or publications.

(a) Within three months following the filing of a request for reexamination under the provisions of section 302, the Director will determine whether a substantial new question of patentability affecting any claim of the patent concerned is raised by the request, with or without consideration of other patents or printed publications. On his own initiative, and any time, the Director may determine whether a substantial new question of patentability is raised by patents and publications discovered by him or cited under the provisions of section 301 or 302 of this title. The existence of a substantial new question of patentability is not precluded by the fact that a patent or printed publication was previously cited by or to the Office or considered by the Office.

Director Must Determine Substantial New Question of Patentability Within 3 Months
Note:
The Director of the USPTO must decide within 3 months if a reexamination request raises a substantial new question of patentability, without considering input from the patent owner unless they filed the request.

35 U.S.C. 303 requires that within 3 months following the filing of a request for reexamination filed under 35 U.S.C. 302, the Director of the USPTO will determine whether or not the request raises a “substantial new question of patentability” affecting any claim of the patent of which reexamination is desired. See also MPEP § 2241. Such a determination may be made with or without consideration of other patents or printed publications in addition to those cited in the request. No input from the patent owner is considered prior to the determination, unless the patent owner filed the request. See Patlex Corp. v. Mossinghoff, 771 F.2d 480, 226 USPQ 985 (Fed. Cir. 1985).

Claims Basis for Substantial New Question of Patentability
Note:
The claims in effect at the time of determination will be used to decide if a new question of patentability has been raised.

The patent claims in effect at the time of the determination will be the basis for deciding whether a substantial new question of patentability has been raised. 37 CFR 1.515(a). Amendments which (1) have been presented with the request if filed under 35 U.S.C. 302 by the patent owner, (2) have been filed in a pending reexamination proceeding in which the certificate has not been issued, or (3) have been submitted in a reissue application on which no reissue patent has been issued, will not be considered or commented upon when deciding requests.

Requirement for Substantial New Question of Patentability in Reexamination Request
Note:
The decision on a reexamination request is based on whether a substantial new question of patentability exists, not on the merits of patentability.

The decision on the request for reexamination filed under 35 U.S.C. 302 has as its object either the granting or denial of an order for reexamination. This decision is based on whether or not “a substantial new question of patentability” is found. A determination as to patentability/unpatentability of the claims is not made in the decision on the request; rather, this determination will be made during the examination stage of the reexamination proceedings if reexamination is ordered. Accordingly, no prima facie case of unpatentability need be found to grant an order for reexamination. If a decision to deny an order for reexamination is made, the requester may seek review by a petition under 37 CFR 1.181. See 37 CFR 1.515(c). See MPEP § 2248. It should be noted that a decision to deny the request for reexamination is equivalent to a final holding (subject only to a petition pursuant to 37 CFR 1.515(c) for review of the denial) that the request failed to raise a substantial new question of patentability based on the cited art (patents and printed publications).

Substantial New Question of Patentability Required for Reexamination
Note:
A substantial new question of patentability must be established for at least one claim to grant reexamination.

It is only necessary to establish that a substantial new question of patentability exists as to one of the patent claims in order to grant reexamination. The Office’s determination in both the order for reexamination and the examination stage of the reexamination ordered under 35 U.S.C. 304 will generally be limited solely to a review of the claim(s) for which reexamination was requested. If the requester was interested in having all of the claims reexamined, requester had the opportunity to include them in its request for reexamination. However, if the requester chose not to do so, those claim(s) for which reexamination was not requested will generally not be reexamined by the Office. It is further noted that 35 U.S.C. 302 requires that “[t]he request must set forth the pertinency and manner of applying cited prior art to every claim for which reexamination is requested.” If the requester fails to apply the art to certain claims, then the requester is not statutorily entitled to reexamination of such claims. If a requester chooses not to request reexamination for a claim, and thus fails to set forth the pertinency and manner of applying the cited art to that claim as required by 37 CFR 1.510(b), that claim will generally not be reexamined. The decision to reexamine any claim for which reexamination has not been requested under 35 U.S.C. 302 lies within the sole discretion of the Office, to be exercised based on the individual facts and situation of each individual case. If the Office chooses to reexamine any claim for which reexamination has not been requested under 35 U.S.C. 302, it is permitted to do so. In addition, the Office may always initiate a reexamination on its own initiative of the non-requested claim (35 U.S.C. 303(a)). See Sony Computer Entertainment America Inc. v. Dudas, 85 USPQ2d 1594 (E.D. Va 2006). It is to be noted that if a request fails to set forth the pertinency and manner of applying the cited art to any claim for which reexamination is requested as required by 37 CFR 1.510(b), a filing date will not be awarded to the request.

Reexamination Limited to Requested Claims
Note:
The Office will generally only review claims for which reexamination was requested during the examination stage of a reexamination ordered under 35 U.S.C. 304.

It is only necessary to establish that a substantial new question of patentability exists as to one of the patent claims in order to grant reexamination.

Office Has Sole Discretion to Reexamine Claims
Note:
The Office can decide on its own to reexamine claims not requested for reexamination, based on individual case facts.

It is only necessary to establish that a substantial new question of patentability exists as to one of the patent claims in order to grant reexamination.

Discussion Order for Reexamination Claims
Note:
The examiner must discuss claims in the order of reexamination, focusing on new questions of patentability without rejecting them.

The decision on the request for reexamination should discuss all of the patent claims requested for reexamination. The examiner should limit the discussion of those claims in the order for reexamination as to whether a substantial new question of patentability has been raised. The examiner SHOULD NOT reject claims in the order for reexamination. Rather, any rejection of the claims will be made in the first Office action (on the patentability of the claims) that is issued after the expiration of the time for submitting any patent owner statement and requester reply that follow the examiner’s order.

Subsequent Ex Parte Reexamination Requests Must Raise New Question
Note:
A second or subsequent request for ex parte reexamination must include prior art that raises a new substantial question of patentability not addressed in the pending proceedings.

If a second or subsequent request for ex parte reexamination is filed (by any party) under 35 U.S.C. 302 while a first ex parte reexamination is pending, the presence of a substantial new question of patentability depends on the prior art (patents and printed publications) cited by the second or subsequent requester. If the requester includes in the second or subsequent request prior art which raised a substantial new question in the pending reexamination, reexamination should be ordered only if the prior art cited raises a substantial new question of patentability which is different from that raised in the pending reexamination proceeding. If the prior art cited raises the same substantial new question of patentability as that raised in the pending reexamination proceedings, the second or subsequent request should be denied.

Requirement for Different Substantial New Question of Patentability
Note:
The Office will deny a second or subsequent request for reexamination unless it provides a different substantial new question of patentability affecting the claims in effect at the time of determination.

The second or subsequent request for reexamination under 35 U.S.C. 302 may provide information raising a substantial new question of patentability with respect to any new or amended claim which has been proposed under 37 CFR 1.530(d) in the first (or prior) pending reexamination proceeding. However, in order for the second or subsequent request for reexamination to be granted, the second or subsequent requester must independently provide a substantial new question of patentability which is different from that raised in the pending reexamination for the claims in effect at the time of the determination. The decision on the second or subsequent request is based on the claims in effect at the time of the determination (37 CFR 1.515(a)). Thus, the second or subsequent request must be directed to the claims of the patent, as modified by any disclaimer, or by any reexamination certificate that has issued as of the time of the determination. If a “different” substantial new question of patentability is not provided by the second or subsequent request for the claims in effect at the time of the determination, the second or subsequent request for reexamination must be denied since the Office is only authorized by statute to grant a reexamination proceeding based on a substantial new question of patentability “affecting any claim of the patent.” See 35 U.S.C. 303. Accordingly, there must be at least one substantial new question of patentability established for the existing claims in the patent in order to grant reexamination.

Requirement for Substantial New Question of Patentability in Reexamination
Note:
A reexamination request must raise at least one new question regarding the patent's claims to be granted.

The second or subsequent request for reexamination under 35 U.S.C. 302 may provide information raising a substantial new question of patentability with respect to any new or amended claim which has been proposed under 37 CFR 1.530(d) in the first (or prior) pending reexamination proceeding.

Second Reexamination Can Address Proposed Claims
Note:
A second reexamination request can include information on proposed new or amended claims to examine the entire patent package when a substantial new question of patentability is raised.

Once the second or subsequent request has provided a “different” substantial new question of patentability based on the claims in effect at the time of the determination, the second or subsequent request for reexamination may also provide information directed to any proposed new or amended claim in the pending reexamination, to permit examination of the entire patent package. The information directed to a proposed new or amended claim in the pending reexamination is addressed during the later filed reexamination (where a substantial new question of patentability is raised in the later filed request for reexamination for the existing claims in the patent), in order to permit examination of the entire patent package. When a proper basis for the second or subsequent request for reexamination is established, it would be a waste of resources to prevent addressing the proposed new or amended claims, by requiring parties to wait until the certificate issues for the proposed new or amended claims, and only then to file a new reexamination request challenging the claims as revised via the certificate. This also prevents a patent owner from simply amending all the claims in some nominal fashion to preclude a subsequent reexamination request during the pendency of the reexamination proceeding.

Examiner Determines Substantial New Question of Patentability Within Three Months
Note:
The examiner must decide within three months after receiving an ex parte reexamination request whether a new question regarding the patent's claims' patentability is raised by the cited prior art.

(a) Within three months following the filing date of a request for an ex parte reexamination, an examiner will consider the request and determine whether or not a substantial new question of patentability affecting any claim of the patent is raised by the request and the prior art cited therein, with or without consideration of other patents or printed publications. A statement and any accompanying information submitted pursuant to § 1.501(a)(2) will not be considered by the examiner when making a determination on the request. The examiner’s determination will be based on the claims in effect at the time of the determination, will become a part of the official file of the patent, and will be given or mailed to the patent owner at the address provided for in § 1.33(c) and to the person requesting reexamination.

Requester Can Seek Review of Denial Decision for Reexamination
Note:
If the request for reexamination is denied, the requester may petition for review under 37 CFR 1.181.

The decision on the request for reexamination filed under 35 U.S.C. 302 has as its object either the granting or denial of an order for reexamination. This decision is based on whether or not “a substantial new question of patentability” is found. A determination as to patentability/unpatentability of the claims is not made in the decision on the request; rather, this determination will be made during the examination stage of the reexamination proceedings if reexamination is ordered. Accordingly, no prima facie case of unpatentability need be found to grant an order for reexamination. If a decision to deny an order for reexamination is made, the requester may seek review by a petition under 37 CFR 1.181. See 37 CFR 1.515(c). See MPEP § 2248. It should be noted that a decision to deny the request for reexamination is equivalent to a final holding (subject only to a petition pursuant to 37 CFR 1.515(c) for review of the denial) that the request failed to raise a substantial new question of patentability based on the cited art (patents and printed publications).

Claims Not Requested for Reexamination Generally Not Examined
Note:
If a requester does not include all claims in the request for reexamination, those claims will generally not be reviewed by the Office.

It is only necessary to establish that a substantial new question of patentability exists as to one of the patent claims in order to grant reexamination. The Office’s determination in both the order for reexamination and the examination stage of the reexamination ordered under 35 U.S.C. 304 will generally be limited solely to a review of the claim(s) for which reexamination was requested. If the requester was interested in having all of the claims reexamined, requester had the opportunity to include them in its request for reexamination. However, if the requester chose not to do so, those claim(s) for which reexamination was not requested will generally not be reexamined by the Office. It is further noted that 35 U.S.C. 302 requires that “[t]he request must set forth the pertinency and manner of applying cited prior art to every claim for which reexamination is requested.” If the requester fails to apply the art to certain claims, then the requester is not statutorily entitled to reexamination of such claims. If a requester chooses not to request reexamination for a claim, and thus fails to set forth the pertinency and manner of applying the cited art to that claim as required by 37 CFR 1.510(b), that claim will generally not be reexamined. The decision to reexamine any claim for which reexamination has not been requested under 35 U.S.C. 302 lies within the sole discretion of the Office, to be exercised based on the individual facts and situation of each individual case. If the Office chooses to reexamine any claim for which reexamination has not been requested under 35 U.S.C. 302, it is permitted to do so. In addition, the Office may always initiate a reexamination on its own initiative of the non-requested claim (35 U.S.C. 303(a)). See Sony Computer Entertainment America Inc. v. Dudas, 85 USPQ2d 1594 (E.D. Va 2006). It is to be noted that if a request fails to set forth the pertinency and manner of applying the cited art to any claim for which reexamination is requested as required by 37 CFR 1.510(b), a filing date will not be awarded to the request.

The Office’s determination in both the order for reexamination and the examination stage of the reexamination ordered under 35 U.S.C. 304 will generally be limited solely to a review of the claim(s) for which reexamination was requested. If the requester was interested in having all of the claims reexamined, requester had the opportunity to include them in its request for reexamination. However, if the requester chose not to do so, those claim(s) for which reexamination was not requested will generally not be reexamined by the Office. It is further noted that 35 U.S.C. 302 requires that “[t]he request must set forth the pertinency and manner of applying cited prior art to every claim for which reexamination is requested.” If the requester fails to apply the art to certain claims, then the requester is not statutorily entitled to reexamination of such claims. If a requester chooses not to request reexamination for a claim, and thus fails to set forth the pertinency and manner of applying the cited art to that claim as required by 37 CFR 1.510(b), that claim will generally not be reexamined. The decision to reexamine any claim for which reexamination has not been requested under 35 U.S.C. 302 lies within the sole discretion of the Office, to be exercised based on the individual facts and situation of each individual case. If the Office chooses to reexamine any claim for which reexamination has not been requested under 35 U.S.C. 302, it is permitted to do so. In addition, the Office may always initiate a reexamination on its own initiative of the non-requested claim (35 U.S.C. 303(a)). See Sony Computer Entertainment America Inc. v. Dudas, 85 USPQ2d 1594 (E.D. Va 2006). It is to be noted that if a request fails to set forth the pertinency and manner of applying the cited art to any claim for which reexamination is requested as required by 37 CFR 1.510(b), a filing date will not be awarded to the request. See MPEP § 2217 and § 2227.

Substantial New Question Depends on Cited Prior Art in Second Ex Parte Reexamination Request
Note:
If a second request for ex parte reexamination is filed while the first is pending, it depends on new prior art cited by the requester to determine if there's a substantial new question of patentability.

If a second or subsequent request for ex parte reexamination is filed (by any party) under 35 U.S.C. 302 while a first ex parte reexamination is pending, the presence of a substantial new question of patentability depends on the prior art (patents and printed publications) cited by the second or subsequent requester. If the requester includes in the second or subsequent request prior art which raised a substantial new question in the pending reexamination, reexamination should be ordered only if the prior art cited raises a substantial new question of patentability which is different from that raised in the pending reexamination proceeding. If the prior art cited raises the same substantial new question of patentability as that raised in the pending reexamination proceedings, the second or subsequent request should be denied.

Decision on Request for Reexamination
Note:
The decision grants or denies an order for reexamination based on whether a substantial new question of patentability is found.

The decision on the request for reexamination filed under 35 U.S.C. 302 has as its object either the granting or denial of an order for reexamination. This decision is based on whether or not “a substantial new question of patentability” is found. A determination as to patentability/unpatentability of the claims is not made in the decision on the request; rather, this determination will be made during the examination stage of the reexamination proceedings if reexamination is ordered. Accordingly, no prima facie case of unpatentability need be found to grant an order for reexamination. If a decision to deny an order for reexamination is made, the requester may seek review by a petition under 37 CFR 1.181. See 37 CFR 1.515(c). See MPEP § 2248. It should be noted that a decision to deny the request for reexamination is equivalent to a final holding (subject only to a petition pursuant to 37 CFR 1.515(c) for review of the denial) that the request failed to raise a substantial new question of patentability based on the cited art (patents and printed publications).

Examiner Should Not Reject Claims In Reexamination Order
Note:
The examiner must not reject claims in the reexamination order but instead make any rejection in a subsequent Office action.

The decision on the request for reexamination should discuss all of the patent claims requested for reexamination. The examiner should limit the discussion of those claims in the order for reexamination as to whether a substantial new question of patentability has been raised. The examiner SHOULD NOT reject claims in the order for reexamination. Rather, any rejection of the claims will be made in the first Office action (on the patentability of the claims) that is issued after the expiration of the time for submitting any patent owner statement and requester reply that follow the examiner’s order.

Proper Meaning of Patent Claims Determined for Ex Parte Reexamination
Note:
The Office will determine the proper meaning of patent claims by giving them their broadest reasonable interpretation consistent with the specification, except for expired patents where claim construction follows Phillips v. AWH Corp principles.

A patent owner claim scope statement and any accompanying information submitted pursuant to 37 CFR 1.501(a)(2) will not be considered by the examiner when making the determination of whether to order ex parte reexamination under 35 U.S.C. 304. This is so, because 35 U.S.C. 301(d) provides that a written statement submitted pursuant to 35 U.S.C. 301(a)(2), and additional information submitted pursuant to 35 U.S.C. 301(c) are not to be considered by the Office for any purpose other than to determine the proper meaning of a patent claim in a proceeding that is ordered pursuant to 35 U.S.C. 304. In making the determination of whether to order reexamination, the Office will determine the proper meaning of the patent claims by giving the claims their broadest reasonable interpretation consistent with the specification (see In re Yamamoto, 740 F.2d 1569, 222 USPQ 934 (Fed. Cir. 1984)), except in the case of an expired patent (in a reexamination involving claims of an expired patent, claim construction is pursuant to the principle set forth by the court in Phillips v. AWH Corp., 415 F.3d 1303, 1316, 75 USPQ2d 1321, 1329 (Fed.

If reexamination is ordered, the patent owner statement, if applicable, and any accompanying information submitted pursuant to 37 CFR 1.501(a)(2) will be considered during the examination stage to the fullest extent possible when determining the scope of any claims of the patent which are subject to reexamination.

The patent claims in effect at the time of the determination will be the basis for deciding whether a substantial new question of patentability has been raised. 37 CFR 1.515(a). Amendments which (1) have been presented with the request if filed under 35 U.S.C. 302 by the patent owner, (2) have been filed in a pending reexamination proceeding in which the certificate has not been issued, or (3) have been submitted in a reissue application on which no reissue patent has been issued, will not be considered or commented upon when deciding requests.

Request Must Address Modified Claims
Note:
The second or subsequent request for reexamination must address the claims as modified by any disclaimers or reexamination certificates issued at the time of determination.

The second or subsequent request for reexamination under 35 U.S.C. 302 may provide information raising a substantial new question of patentability with respect to any new or amended claim which has been proposed under 37 CFR 1.530(d) in the first (or prior) pending reexamination proceeding. However, in order for the second or subsequent request for reexamination to be granted, the second or subsequent requester must independently provide a substantial new question of patentability which is different from that raised in the pending reexamination for the claims in effect at the time of the determination. The decision on the second or subsequent request is based on the claims in effect at the time of the determination (37 CFR 1.515(a)). Thus, the second or subsequent request must be directed to the claims of the patent, as modified by any disclaimer, or by any reexamination certificate that has issued as of the time of the determination. If a “different” substantial new question of patentability is not provided by the second or subsequent request for the claims in effect at the time of the determination, the second or subsequent request for reexamination must be denied since the Office is only authorized by statute to grant a reexamination proceeding based on a substantial new question of patentability “affecting any claim of the patent.” See 35 U.S.C. 303. Accordingly, there must be at least one substantial new question of patentability established for the existing claims in the patent in order to grant reexamination.

Proposed New Claims During Reexamination
Note:
Patent owners can address proposed new or amended claims during the reexamination process if a proper basis for a second or subsequent request is established, without waiting for a certificate to issue.

Once the second or subsequent request has provided a “different” substantial new question of patentability based on the claims in effect at the time of the determination, the second or subsequent request for reexamination may also provide information directed to any proposed new or amended claim in the pending reexamination, to permit examination of the entire patent package. The information directed to a proposed new or amended claim in the pending reexamination is addressed during the later filed reexamination (where a substantial new question of patentability is raised in the later filed request for reexamination for the existing claims in the patent), in order to permit examination of the entire patent package. When a proper basis for the second or subsequent request for reexamination is established, it would be a waste of resources to prevent addressing the proposed new or amended claims, by requiring parties to wait until the certificate issues for the proposed new or amended claims, and only then to file a new reexamination request challenging the claims as revised via the certificate. This also prevents a patent owner from simply amending all the claims in some nominal fashion to preclude a subsequent reexamination request during the pendency of the reexamination proceeding.

Patent Litigation Review Required Before Reexamination Determination
Note:
Before deciding on a reexamination request, a litigation search must be conducted to check if the patent is involved in any litigation.

Before making a determination on the request for reexamination filed under 35 U.S.C. 302, a litigation search from the Technical Support Staff (TSS) of the Central Reexamination Unit (CRU) or the Scientific and Technical Information Center (STIC) must be done to check if the patent has been, or is, involved in litigation. The “Litigation Review” box on the reexamination IFW file jacket form (RXFILJKT) should be completed to indicate that the review was conducted and the results thereof. A copy of the litigation search and the reexamination file jacket form are scanned into the IFW reexamination file history. In the rare instance where the record of the reexamination proceeding or the litigation search indicates that additional information is desirable, guidance as to making an additional litigation search may be obtained from the library of the Office of the Solicitor. If the patent is or was involved in litigation, and a paper referring to the court proceeding has been filed, reference to the paper by number should be made in the “Litigation Review” box on the reexamination IFW file jacket form as, for example, “litigation; see paper filed 7-14-2005.” If a litigation records search is already noted on the file, the examiner need not repeat or update it before making a determination on the request.

AWH Corp., 415 F.3d 1303, 1316, 75 USPQ2d 1321, 1329 (Fed. Cir. 2005) (words of a claim “are generally given their ordinary and customary meaning” as understood by a person of ordinary skill in the art in question at the time of the invention, see Ex parte Papst-Motoren, 1 USPQ2d 1655 (Bd. Pat. App. & Inter. 1986)). If reexamination is ordered, the patent owner statement, if applicable, and any accompanying information submitted pursuant to 37 CFR 1.501(a)(2) will be considered during the examination stage to the fullest extent possible when determining the scope of any claims of the patent which are subject to reexamination.

Examiner’s Determination for Ex Parte Reexamination
Note:
The examiner's determination on a request for ex parte reexamination must be based on the claims in effect at the time of the determination and will become part of the official patent file.

(a) Within three months following the filing date of a request for an ex parte reexamination, an examiner will consider the request and determine whether or not a substantial new question of patentability affecting any claim of the patent is raised by the request and the prior art cited therein, with or without consideration of other patents or printed publications. A statement and any accompanying information submitted pursuant to § 1.501(a)(2) will not be considered by the examiner when making a determination on the request. The examiner’s determination will be based on the claims in effect at the time of the determination, will become a part of the official file of the patent, and will be given or mailed to the patent owner at the address provided for in § 1.33(c) and to the person requesting reexamination.

Rejections Must Be In First Office Action After Replies
Note:
Rejections of claims must be made in the first office action on patentability after all required replies have been submitted.

The decision on the request for reexamination should discuss all of the patent claims requested for reexamination. The examiner should limit the discussion of those claims in the order for reexamination as to whether a substantial new question of patentability has been raised. The examiner SHOULD NOT reject claims in the order for reexamination. Rather, any rejection of the claims will be made in the first Office action (on the patentability of the claims) that is issued after the expiration of the time for submitting any patent owner statement and requester reply that follow the examiner’s order.

Second Request Must Raise New Patentability Question
Note:
The second or subsequent request for reexamination must independently provide a new substantial question of patentability not addressed in the first pending reexamination.

The second or subsequent request for reexamination under 35 U.S.C. 302 may provide information raising a substantial new question of patentability with respect to any new or amended claim which has been proposed under 37 CFR 1.530(d) in the first (or prior) pending reexamination proceeding. However, in order for the second or subsequent request for reexamination to be granted, the second or subsequent requester must independently provide a substantial new question of patentability which is different from that raised in the pending reexamination for the claims in effect at the time of the determination. The decision on the second or subsequent request is based on the claims in effect at the time of the determination (37 CFR 1.515(a)). Thus, the second or subsequent request must be directed to the claims of the patent, as modified by any disclaimer, or by any reexamination certificate that has issued as of the time of the determination. If a “different” substantial new question of patentability is not provided by the second or subsequent request for the claims in effect at the time of the determination, the second or subsequent request for reexamination must be denied since the Office is only authorized by statute to grant a reexamination proceeding based on a substantial new question of patentability “affecting any claim of the patent.” See 35 U.S.C. 303. Accordingly, there must be at least one substantial new question of patentability established for the existing claims in the patent in order to grant reexamination.

Petition Under 37 CFR 1.182 for Harassment Purposes
Note:
If a patent owner files a petition under 37 CFR 1.182 as part of a second or subsequent ex parte reexamination request with clear intent to harass, the request will be suspended and not merged with existing proceedings.

In certain situations, after a grant of a second or subsequent request for ex parte reexamination, where (A) the patent owner files a petition under 37 CFR 1.182 as part of the statement or as the statement, and (B) it appears clear that the second or subsequent request was filed for purposes of harassment of the patent owner, if the petition is granted, prosecution on the second or subsequent reexamination would be suspended. Merger of such a second or subsequent request with the already pending reexamination proceeding(s) would unduly prolong the conclusion of the pending reexamination and be inconsistent with the requirement that reexamination proceeding be conducted with special dispatch.
