Appeal No. 1997-0896
Application 08/141,610
Appellant challenges the Examiner’s Official Notice and
complains that the Examiner has not come forward with evidence
of such. We find no further evidence required. Run length
encoding is admitted by Appellant (APA) to be well known, as
exemplified by Aono.
Appellant argues that his run length encoding “outputs a
terminated run length by using the bit of the second value in
the bits to be run length encoded to terminate the string of
bits of the first value and likewise by using the bit of the
first value in the bits to be run length encoded, to terminate
the string of bits of the second value.” which is not shown by
the prior art. Also, “Both of the encoding techniques
disclosed in Aono code strings of bits of one value only.”
(Brief-pages 10 and 11.)
We agree with the Examiner, the recited distinctions are
not distinctions, and are found in the well known run length
encoding shown in Aono. The Examiner points to column 1,
lines 54-62, where run length encoding is used for 1s or 0s,
1s representing white, and 0's representing black. Here, we
read “or” as “and”, meaning that both white and black are run
length encoded.
