Appeal No. 2002-1318
Application No. 08/693,662
is argued (brief, page 5) that the system taught by West in view
of Downey, would not suggest incorporating the teachings of
Dockery because communication signals are already successfully
coupled between separate lines with a wireless link, which
includes the use of a transmitter and receiver. Appellants
further argue (id.) that in West in view of Downey, neither
reference suggests using a power line as an antenna to accomplish
the task of communicating signals between separate power lines.
It is further argued (id.) that there is no teaching in West,
Downey or Dockery for using stray propagation from a power line,
and (brief, page 6) that none of the references teaches the
sensing of data where the signal is an unintended byproduct of
communication in a network.
From our review of the record, we find that the issue before
us is whether it would have been obvious to have deleted the RF
transmitter in the combined teachings of West and Downey, in view
of the disclosure of Dockery. With regard to appellants'
assertion (brief, page 6) that none of the references teaches the
sensing of data where the signal is the unintended byproduct of
communications in a network, we note that appellants' claims do
not recite that the sensed signal is an unintended byproduct of
communications in a network. Nor do appellants' claims recite
