Appeal No. 1996-3591 Application No. 08/251,053 language of Appellants’ claim 8, we find Masaki’s teaching of a voltage divider to be cumulative to that of Iyengar which clearly illustrates a voltage divider 118, 120 in the multiplier circuit of Figure 7. Further, after considering the Examiner’s analysis (Answer, page 5) of the limitations of Appellants’ claim 8, it is our view that all of the claimed elements exist in the multiplier circuit illustrated in Figure 7 of Iyengar. The claimed comparator is illustrated at 94 of Iyengar’s Figure 7 and is shown coupled to a stabilizing feedback circuit with the voltage at node 108 equaling the voltage at line MVA (Iyengar, col. 17, lines 48-53). The voltage divider 118, 120 of Iyengar in turn operates to reduce the multiplied voltage dependent on the values of resistors 118 and 120 as described at column 16, lines 38-42. Further, we agree with the Examiner’s analysis (Answer, page 6) that Iyengar’s P-channel transistors 110 and 112 and voltage divider resistors 118 and 120 meet all of the requirements of dependent claims 9-14. Accordingly, all of the elements of claims 8-14 have been shown to be fully disclosed by Iyengar. A disclosure that anticipates under 35 U.S.C. § 102 also renders the claim unpatentable under 35 U.S.C. § 103, for 12Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
