taught by the input of these value [sic] into the
fuzzy inference portion 51. Membership values are
obtained by calculation through fuzzy MIN and MAX
arithmetic operations.
Appellant asserts (brief, page 7), inter alia, that Mega
does not teach or suggest calculating fuzzy control parameters
for tuning the fuzzy logic controller, and that (reply brief,
page 2) “[n]owhere does Mega tune the fuzzy logic controller
using fuzzy control parameters.” We agree. We find that in
Mega (col. 4, line 40 et seq.), the inputs I , I and I to the1 2 3
fuzzy inference portion 51 are the differences between the
deviation signals (A-B), the integral value of the difference
(A-B), and the differential value of the differences (A-B),
respectively. However, we find that the input of the values
I , I and I into the fuzzy inference portion, and the1 2 3
subsequent calculation of membership values do not tune the
fuzzy inference unit as required by independent claims 1 and
14. We find that Mega discloses (col. 4, line 64 - col. 5,
line 28) that the values I , I and I are input into three1 2 3
membership value arithmetic circuits 55, which read out
membership functions stored in antecedent membership function
memory 56, and obtain membership values by calculating through
