Application 08/330,335
unpatentable over Gabbitas in view of
Flannery and Merlo and further in view
of Raudonat.
Claim 4 depends from claim 1 and recites that the
signal processor contains Fourier transform means and
frequency discrimination means. The examiner adds Raudonat to
the combination just discussed because Raudonat teaches the
use of the Fourier transform in processing Doppler signals.
The examiner’s rationale for adding the teachings of Raudonat
to the
teachings of Flannery, Merlo and Gabbitas is sufficient to
establish a prima facie case of obviousness.
Appellant makes the same arguments discussed above and
argues that the modification of the applied references would
destroy the intended functions of each of the references
[brief, page 26]. We do not agree with this argument of
appellant. The rejection does not propose that the teachings
of the references should be poured into a pot and the contents
stirred. Rather, the rejection looks at Flannery as the
principle reference teaching a dual channel Doppler frequency
detector. Gabbitas is cited only to teach the obviousness of
