Claim Basis for Substantial New Question of Patentability
Note:
The claims in effect at the time of determination will be used to decide if a substantial new question of patentability is present during reexamination.

The claims of the patent in effect at the time of the determination will be the basis for deciding whether “a substantial new question of patentability” is present. 37 CFR 1.515(a). The Office’s determination in both the order for reexamination and the examination stage of the reexamination under 35 U.S.C. 302 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 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), 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)). Thus, while the examiner will ordinarily concentrate on those claims for which reexamination is requested, the finding of “a substantial new question of patentability” can be based upon a claim of the patent other than the ones for which reexamination is requested, if reexamination is requested under 35 U.S.C. 302. For example, the request filed under 35 U.S.C. 302 might seek reexamination of particular claims, but the examiner is not limited to those claims and can make a determination that “a substantial new question of patentability” is present as to other claims in the patent without necessarily finding “a substantial new question” with regard to the claims for which reexamination was requested.

Claim Requires Cited Art Application for Reexamination
Note:
A claim must demonstrate how cited art applies to it for reexamination to proceed.

Note:
The Office may reexamine claims not requested for reexamination under 35 U.S.C. 302 based on individual case facts and circumstances.

The claims of the patent in effect at the time of the determination will be the basis for deciding whether “a substantial new question of patentability” is present. 37 CFR 1.515(a).

Note:
The Office will generally limit reexamination to the claims specified in the request, unless the Office decides otherwise based on individual circumstances.

The claims of the patent in effect at the time of the determination will be the basis for deciding whether “a substantial new question of patentability” is present. 37 CFR 1.515(a). The Office’s determination in both the order for reexamination and the examination stage of the reexamination under 35 U.S.C. 302 will generally be limited solely to a review of the claim(s) for which reexamination was requested.

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)). Thus, while the examiner will ordinarily concentrate on those claims for which reexamination is requested, the finding of “a substantial new question of patentability” can be based upon a claim of the patent other than the ones for which reexamination is requested, if reexamination is requested under 35 U.S.C. 302. For example, the request filed under 35 U.S.C. 302 might seek reexamination of particular claims, but the examiner is not limited to those claims and can make a determination that “a substantial new question of patentability” is present as to other claims in the patent without necessarily finding “a substantial new question” with regard to the claims for which reexamination was requested.
