network and determine whether the increment/decrement network or the temporary
register will be selected to provide the most significant byte of the result.” The
Examiner further argues that Daniels’ Figures 5 and 7 demonstrate that the output
of the multiplexer in Daniels is a function of the carry-out. The carry-out signal
affects the intermediate signal B7C in Figure 5, which, as shown in Figure 7,
affects whether the increment/decrement network (INCH) or the temporary register
(TEMPH) is output to the high-order address bus (ABH) (Answer 5).
Appellants further argue that the sign bit of the second binary operand does
not qualify as proper selection data. (Reply Br. 5). Although Appellants’ statement
is factually correct, as stated by the Examiner (Answer 5), it does not apply to the
carry-out signal. The output to ABH bus is a function of both the sign bit and the
carry-out. (Daniels Abstract). Thus, whether or not the sign bit satisfies the
selection data criteria, we are convinced by the Examiner’s assertion that the carry-
out signal constitutes the selection data.
We note that independent claims 18 and 19 recite similar limitations which,
as discussed above, are taught by Daniels. Thus, we sustain the 35 U.S.C. § 102
rejection of independent claims 1, 18, and 19, as well as dependent claims 2, 3, 5,
6, 8-10, and 12-17 argued together as one group (Br. 8).
