fuzzy MIN arithmetic operations, which results in the output
of membership values to fuzzy output arithmetic circuit 57.
The fuzzy inference circuit is based on a rule format (col. 4,
lines 52 and 53). Rules R1-R10 (col. 5, lines 1-10) utilize
an IF-Then format. Fuzzy output arithmetic circuit 57 reads
out rules R1-R10 stored in rule memory 58 and membership
functions stored in a consequent membership function memory
59. Fuzzy arithmetic output circuit 57 then obtains fuzzy
output K through a fuzzy max arithmetic operation.

From our review of Mega, we find no tuning of the fuzzy
inference circuit, and are in agreement with appellant (reply
brief, page 2) that “careful inspection of the Mega reference
indicates that these values do not tune the fuzzy controller,
but rather are simply the inputs that determine the outputs of
the fuzzy logic controller.” We therefore find that Mega does
not anticipate claim 1. With regard to claim 14, we
additionally find that Mega does not disclose the claimed
“tuning module.” Accordingly, the rejection of claims 1 and
14 under 35 U.S.C. § 102(e) as unpatentable over Mega is
reversed. As claims 9 and 10 depend from claim 1, the
