Appeal No. 1998-1319
Application No. 08/466,188
499, 501 (1990)). Without knowing what each claim defines, we
cannot determine whether the claims distinguish over the prior
art. Accordingly, before analyzing the rejections, we must
determine the scope of the various claims.
Each of claims 9, 10, 15, 18 through 29, 31, and 33
through 44 specifies in pertinent part the generation of
plural tone voltages. Specifically, claims 9, 10, 28, and 29
each recite (emphasis added) a device for "generating a
plurality of tone voltages." Similarly, claims 18, 19, and 23
through 27 recite (emphasis added) "a voltage generator for
... generating a plurality of discrete output signals at
respectively different voltage levels." Claims 20 through 22,
31, and 33 specify (emphasis added) that "2 different voltageN
levels" are generated." The method of claim 15 includes
(emphasis added) "generating a plurality of multi-tone
displaying voltages," and the methods of claims 36 and 41
recite (emphasis added) "producing a plurality of different
multi-tone voltages." Methods of claims 38 and 43 specify
that "2 kinds of voltage levels" are produced. Claims 34,N
35, 37, 39, 40, and 42 each include a step of "producing
multi-tone voltage selecting data." For voltages to be
