Appeal 2007-2258
Application 09/738,054
ISSUE
The issue is whether the Examiner erred in rejecting the appealed
claims under 35 U.S.C § 103(a). With respect to appealed claims 1 and 3,
would one of ordinary skill in the art at the time of the invention have found
it obvious to combine Goodman and Chau to render the claimed invention
unpatentable?
FINDINGS OF FACT
The following findings of fact (FF) are believed to be supported by a
preponderance of the evidence.
1. Goodman relates to a system that provides video signal
communication between a source of the video signal and a plurality of units
that includes an interface coupled to the source and to telephone lines, each
of which serves at least one of the units and carries voice signals to and from
one or more telephones coupled to the telephone line at said unit. (Abstract).
2. Goodman discloses that in many office buildings, the telephone
wiring is not the only network of twisted pair wiring that extends to each
office and converges at a common point. Over the past several years,
common communication networks that connect personal computers, known
as Local Area Networks or LANs, have begun to use twisted pair wiring for
their conductive paths. In the typical configuration, a digital electronic
device serves as the “hub” for such a system, and a separate twisted pair
wire connects from this center to each of the computer nodes. In this
application, the technique for communication across a public network trunk
(PBX) is expanded to provide the same capabilities for wiring networks that
