Appeal No. 2001-1596 Application 09/296,102 In effect, the examiner seems to be retroactively applying the Nov. 7, 2000 amendment of the rules, supra, by which this provision was removed from § 1.104(e), but an agency does not have the authority to promulgate retroactive rules unless expressly given that authority by Congress, Motion Picture Assn. of America Inc. v. Oman, 969 F.2d 1154, 1156, 23 USPQ2d 1447, 1449 (D.C.Cir. 1992), and the PTO has not been given such authority. Moreover, even if present 37 CFR § 1.104(e) had been in effect when appellants’ original application was pending, we do not consider that the recapture rule would preclude them from obtaining the claims now on appeal. Discussing what may constitute a surrender for purposes of the recapture rule, the Court in Hester Industries, 142 F.3d at 1481, 46 USPQ2d at 1648, stated that: as a general proposition, in determining whether there is a surrender, the prosecution history of the original patent should be examined for evidence of an admission by the patent applicant regarding patentability. . . . In this regard, claim amendments are relevant because an amendment to overcome a prior art rejection evidences an admission that the claim was not patentable. . . . Arguments made to overcome prior art can equally evidence an admission sufficient to give rise to a finding of surrender. . . . Logically, this is true even when the arguments are made in the absence of any claim amendment. Amendment of a claim is not the only permissible predicate for establishing a surrender. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
