indicated by the examiner. According to the appellant,
however (Brief at pages 4-5), (1) simply combining SCSI
controller and Ethernet controller onto a single integrated
circuit chip will not create a device functioning within an
acceptable error margin, (2) taking standard steps to isolate
analog and digital components on an integrated Ethernet and
SCSI controller will not reduce errors in the analog circuitry
below an acceptable margin , and (3) including additional
noise reduction circuitry, as further claimed in claim 1,
necessary to reduce noise within an acceptable error margin,
is not disclosed by Duschatko and is not within the knowledge
of one with ordinary skill in the art.
The appellant’s arguments are not commensurate in scope
with the features recited in claim 1. Claim 1 is broader in
scope and does not support the arguments on which the
appellant relies. For instance, insofar as noise reduction is
concerned, claim 1 simply recites that “circuitry on the
integrated circuit chip is configured to limit noise generated
in the analog circuitry by signals in the digital control
circuitry.” Claim 1 does not require that digital noise be
sufficiently reduced such that the analog circuitry in the
