Appeal No. 1998-0747
Application 08/609,958
these claims is met by Yajima. Accordingly, these claims fall
with claim 1.
Claims 3, 4, 8-18 and 22-31 are rejected under 35 U.S.C. §
103 as unpatentable over Yajima and Entenman. Yajima teaches a
redundancy type system of components comprising processing units
11 and 12. Entenman teaches a redundancy system of components
comprising modems 10. Whereas modems are processing units, it
would have been obvious to one of ordinary skill in the art at the
time the invention was made to utilize Entenman’s modems as the
processing units in Yajima. Section 103 requires us to presume
that the artisan has full knowledge of the prior art in his field
of endeavor and the ability to select and utilize knowledge from
analogous arts. In re Deminski, 796 F.2d 436, 442, 230 USPQ 313,
315 (Fed. Cir. 1986).
With respect to dependent claims 15-17, the examiner took the
position in the answer that it would have been obvious to provide
a chassis for housing the modems of Entenman and that the
motivation to do so would have been to protect the actual
circuitry. We agree. A conclusion of obviousness may be made from
common knowledge and common sense of the person of ordinary skill
in the art without any specific hint or suggestion in a particular
