said quantizing vectors of a training pattern classified in
the same label series of clusters and the continuous
probability distribution density HMM." Similarly, claim 9,
the other independent claim, specifies in pertinent part the
following limitations: "vector quantizing means connected to
said word pattern memory means for quantizing vectors of a
training pattern received from said word pattern memory means
and converting said quantizing vectors into a label series of
clusters to which they belong . . . and label incidence
calculating means connected to said parameter memory means for
calculating the incidence of the labels in each state from
said quantizing vectors of a training pattern classified in
the same label series of clusters and the continuous
probability distribution density HMM.”
Having determined what subject matter is being claimed,
the next inquiry is whether the subject matter is obvious.
"’A prima facie case of obviousness is established when the
teachings from the prior art itself would appear to have
suggested the claimed subject matter to a person of ordinary
skill in the art.’" In re Bell, 991 F.2d 781, 782, 26 USPQ2d
