Application No. 09/002,173
applied “regardless of the generation of the carry bit Ci in the
carry lookahead circuit on its right” [column 3, lines 15-16, of
Tomoji].
The examiner argues that this second circuit is disclosed by
Tomoji by “the corresponding circuit that provide [sic, provides]
the limited carry to gates 332 and 336" [answer-page 4].
However, whatever is providing this limited carry in Tomoji
always supplies the same suspense carry bit and so it is not
“based only on K bits of said augend and K bits of said
addend...,” as claimed.
Accordingly, since an important claim limitation is absent
from the teachings of Tomoji, Tomoji cannot anticipate the
claimed subject matter and we will not sustain the rejection of
claims 1-7 and 9-11 under 35 U.S.C. 102(b).
Similarly, since we find no reason to modify Tomoji to
provide for this deficiency, we also will not sustain the
rejection of claim 8 under 35 U.S.C. § 103.
