which claims 11 and 12 depend, that are not present in claim
1, from which claims 3 and 4 depend. Specifically, as noted
supra, we find that claim 9's limitation of "generating a set
of identifiers" which signify rising slope, falling slope, or
no slope is taught by Toyama. Because that limitation is not
present in claim 1, we are not persuaded that claims 11 and 12
should be patentable for the same reasons that claims 3 and 4,
respectively, are patentable.
With respect to claims 11 and 12, we find that Kao
teaches character recognition "by finding a correlation
between the normalized waveshape and one of the defined
character waveform patterns stored in ROM" (column 6, lines
16-19). Kao thus teaches comparing amplitude ratios (i.e.,
normalized amplitudes) of the samples of each set with
predetermined sets of amplitude ratios, in order to identify
which character has been read. We further find that Roberts
teaches applying plural pattern recognition techniques to a
set of input data, and selecting an output from among the
recognition methods (see column 2, lines 1-12, and Figure 3).
We find that those skilled in the art, having the
