source knowledge in tools which build the
fuzzy reasoning system. This poses the
problem that when a situation in making the
reasoning has changed, the produced system
fails to conform to the new situation, or
that the system cannot conform to a plurality
of situations. In such a case, it is
necessary to reproduce the system or to
produce a plurality of systems. It is
accordingly very difficult to cope with
various situations.
It is this fixed and inflexible association which the appellants
seek to avoid. The specification at 3 states:
In the first aspect of the present invention,
a plurality of fuzzy sets conforming to the sorts
of situation are prepared in correspondence with
one fuzzy rule group beforehand, whereby the fuzzy
set to be used can be dynamically altered at the
time of execution of reasoning.
Sakai does not anticipate the appellants’ claimed invention

which applies multiple levels of fuzzy reasoning by use of up to
