space neighborhood of required precision. The Examiner
further offers an analogy of increasing the amount of “bins”
which receive data and correspond to the contiguous vertical
bars in the Fig. 4 histogram of Hanson dependent on the
precision required. Upon a careful review of DARPA and
Hanson, we find that neither reference teaches the claimed
calculation of neighborhood input space. While we agree with
the Examiner that the setting up of a histogram such as
illustrated in Hanson involves a quantization of input space,
such quantization does not involve a calculation of a
neighborhood of input space which satisfies the required
precision of single output data. We further agree with
Appellants (page 8 of reply brief) that Hanson is silent as to
the expression of a calculated neighborhood as a quantization
number as claimed.
Appellants further argue on pages 20 and 21 of the Brief
that DARPA does not teach the enlargement of the calculated
neighborhood to extract similar cases and further does not
teach a similarity determination based on a predetermined
degree of enlarging. Appellants recite in claim 1
