Appeal No. 96-4014
Application 08/192,939
description of the proportional-integral controller in
Appellant's specification is not prior art.
The examiner does not address appellants' arguments. In our
opinion, it would be misleading to argue that "[t]here is no
statement disclosing that conventional proportional-integral
controllers are currently being used or can be used with the
prior art control system disclosed in Fig. 2 of Appellant's
specification" (Brief, page 12), if appellants were in fact aware
that proportional-integral controllers were used or can be used
in the prior art control system. Thus, on this record, we have
no evidence establishing a prima facie case of obviousness with
respect to the proportional-integral controllers of claims 12 and
18 or the fuzzy proportional-integral controllers of claims 13
and 19. The rejection of claims 12, 13, 18, and 19 is reversed.
Appellants' arguments
1.
Appellants argue that Hisano does not disclose the claimed
limitations of: (1) a plurality of low-level controllers;
(2) a fuzzy logic hierarchical controller connected to the
low-level controllers; and (3) the fuzzy logic hierarchical
controller generating a single output value derived from an
aggregation of control variable values. These three limitations
are common to all three independent claims 7, 14, and 20.
