respectively, from MPU 1 (col. 5, lines 32-36). The outputs
of these drivers/ receivers are connected to bus width
converter 302, which includes drivers/receivers 302 , 302 ,1 3
302 , and 302 for outputting 16-bit or 8-bit data (col. 5,4 5
lines 39-51). The examiner contends it would have been
obvious
to utilize Kinoshita's bus convertor in the
combined Bowater and Grants's memory
interface controller because it would have
further increased the utility of the memory
controller by enabling the processor to
interface with various memory devices
having different data widths. [Answer at
8.]
Appellants argue that the teachings of the references thus
combined will not satisfy claim 11's requirement for "an
external
port having . . . a plurality of bus size input lines" and a
"decoding circuit . . . for sampling input on said bus size
input lines." We agree with this argument, which has not been
addressed by the examiner. Kinoshita does not disclose or
suggest automatically determining bus size by sampling input
signals from an external port or a device coupled thereto.
Nor is this suggestion found in Kinoshita considered with
