Appeal No.2003-1091 Application No. 09/484,248 rely on assertions made with respect to claim 1, i.e., that Butcher fails to disclose the single step selection of a plurality of delay elements. As previously discussed, we find these arguments unpersuasive since the language of claim 1 does not require the selection of a plurality of delay elements but, rather, only the single step selection of “up to a plurality of delay elements.” Since Appellant, by the presented arguments, has chosen to let the rejection of claims 2-8, 11-13, and 18-20 stand or fall with claim 1, the Examiner’s 35 U.S.C. § 103(a) rejection of these claims is sustained. Note In re King, 801 F.2d 1324, 1325, 231 USPQ 136, 137 (Fed. Cir. 1986); In re Sernaker, 702 F.2d 989, 991, 217 USPQ 1, 3 (Fed. Cir. 1983). We have taken note of Appellant’s presentation, for the first time, in the Reply Brief of arguments directed to claims 2 and 20, as well as the discussion of features of other unspecified claims. We will not consider these new arguments. Because an Examiner is no longer permitted to file sua sponte a supplemental Examiner’s Answer in response to a Reply Brief, 37 CFR § 1.193(b)(1)(1998), we do not have the benefit of the Examiner’s response to Appellant’s new arguments. Considering the new arguments would not only be unfair but would entail the risk of an improvident or ill-advised opinion. Cf.
