similarity values obtained by the recognizing means using the signal patterns for learning; and
means for obtaining new reference patterns from the feature vectors for learning
extracted by the extracting means and storing the obtained new reference patterns in the
recognition dictionary means.
The examiner relies on the following references:
Takebayashi et al (Takebayashi) 4,783,802 November 8, 1988
Bahler 4,481,593 November 6, 1984
Claims 1 through 15 stand rejected under 35 U.S.C. 103 as unpatentable over Takebayashi in
view of Bahler.
Reference is made to the brief and answer for the respective details of the positions of appellants
and the examiner.
OPINION
We reverse.
Each of the independent claims 1, 6 and 11 contains limitations requiring, inter alia, that the time
series signals are recognized according to “a word spotting scheme” and that the means for learning new
reference patterns to be stored in the recognition dictionary means includes a “means for extracting feature
vectors for learning from the recognition results...”[emphasis ours]. Thus, every claim requires a
combination of using word spotting, which uses a continuous pattern matching, as the recognizing scheme,
and a learning scheme which employs the results from the recognition unit (note the connection between
