Appeal No. 97-0425 Application 08/330,335 using a Schottky barrier mixer cavity for the Doppler detector in Flannery. Raudonat is cited only to teach the obviousness of performing the Flannery processing using Fourier transforms. Finally, Merlo is cited only to teach the obviousness of modifying the Flannery fixed low pass filters to programmable filters which are controlled by the vehicle’s own velocity. None of these modifications destroys the basic nature of the Flannery device which is to determine the relative velocity between two vehicles. Since no other arguments are presented by appellant, we sustain the rejection of claims 4 and 5. 6. The rejection of claim 10 as unpatentable over Gabbitas in view of Flannery and Merlo and further in view of Fritzlen. Claim 10 depends from claim 9 and adds the recitation that the frequency comparison means are phase locked loops. The examiner cites Fritzlen to teach this feature and indicates why the invention of claim 10 would have been obvious within the meaning of 35 U.S.C. § 103 [Final Rejection, pages 6-7]. -15-Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
