Appeal No. 1997-3182 Application 08/254,643 G and G . The examiner's rejection mistakenly attributes2 1 features of the sum modifier circuit 26 to the difference modifier circuit 30 in the answer. Figure 1 contains circuits which delay the difference (A-B) signals on line 24 and the sum (A+B) signals on line 20 relative to each other, but not with respect to the left and right input signals per se as required by the language of the detector circuit quoted above in each independent claim 1 and 21 on appeal. At most, any phase shift attributed to the difference signal A-B would not be equal or equivalent to, within 35 U.S.C. § 102, the "relative phase" of the input signals, per se as claimed. As such, the claimed first multiplier circuit of claim 1 and the multiplier circuit of claim 21 on appeal also cannot be met by the teachings and showings associated with Figure 1 of Robinson. Because we have reversed the rejection under 35 U.S.C. § 102 of independent claims 1 and 21 on appeal, we also reverse the rejection of their respective dependent claims 8 and 22. Furthermore, we reverse the respective rejections of claims 15, 16 and 27 under 35 U.S.C. § 103 even in light of the 7Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
