any suggestion as to modifying anything in Noguchi? Noguchi has error correction circuitry
[column 2, lines 47-50], and there is no indication that there is any problem therewith.
Therefore, there would have been no reason for the artisan to look to add an error
correction circuit to Noguchi.
The examiner contends that it would have been obvious to employ alternative error
correction circuits. However, we agree with appellants that Noguchi provides the error
correction circuitry at the input/output of memory 26 in order to prevent errors in the
memory operation. In Kondo, block code data is transmitted and used to correct errors
that might be present in quantized data. We are at a loss to see why, without guidance
from appellants’ disclosure, the artisan would have eliminated the error correction circuitry
from the input/output of Noguchi’s memory and placed it elsewhere in the system, as
disclosed by Kondo.
Moreover, even if the artisan would have been led, in some manner, to do so, it is
still not clear to us how one arrives at the instant claimed subject matter.
Claim 1 calls for a very specific combination of elements and interrelated functions.
The signal processor has the interleave write data and the amplifier has the
circuit for restoring the interleave data. The processor and the amplifier are
interconnected by a plurality of signal lines and each of the plurality of interleave write data
