Appeal No. 1997-4221 Page 7
Application No. 08/255,518
“without any delay to the data transfer operation,” as claimed.
Since the encoder/decoder of Tsang is not connected to the bus,
in parallel with the modules, as disclosed and suggestively
claimed by appellant, it would appear that there would be an
inherent delay in any data transfer in Tsang, unlike the
instant claimed system. We do not find that the artisan would
have found any advantage in attempting to modify the Deroo
system with that of Tsang even if such a combination was,
somehow, suggested by the prior art which, in our view, the
examiner has not shown.
In our view, the examiner has chosen, without any
suggestion in the prior art for doing so, bits and pieces of
the instant claimed invention from the prior art (the data
transfer of Deroo and the “on-the-fly” teaching of Tsang) and
thrown these pieces together in a haphazard attempt to meet the
instant claim language. 35 U.S.C. 103 requires some reasonable
suggestion for combining the teachings of the prior art. We
find no such suggestion in the evidence provided by the
examiner.
