Appeal No. 2005-0116 Application No. 10/109,390 establish a genuine issue of material fact." Dembiczak, 175 F.3d at 999, 50 USPQ2d at 1617, citing McElmurry v. Arkansas Power & Light Co., 995 F.2d 1576, 1578, 27 USPQ2d 1129, 1131 (Fed. Cir. 1993). The examiner relies upon the teachings of Merrill to teach the additional limitation in claim 3 with respect to the use of a buffer at the output of the circuit. The examiner relies upon the teachings of Gowda to teach the additional limitation in claims 4 and 5 with respect to the use of the second reference signal a subsequent first reference signal. Appellants do not contest the teachings of Merrill or Gowda, but maintain that they do not remedy the deficiencies in Fossum as noted above. We agree with appellants and find that the examiner has not established a prima facie case of obviousness of the claimed invention. With respect to independent claim 6, the examiner relies upon the teachings of Dhuse in combination with Booth, Jr. as evidence of obviousness of the detailed limita- tions of independent claim 6. From our review of the teachings of Dhuse, we agree with appellants’ (Brief at pages 6-7) that Dhuse is deficient with respect to the second black reference signal branch and that the teachings of Booth, Jr. do not fairly suggest the use of separate and distinct branch circuits for the same pixel and use thereof for black reference signals to modify the pixel signal. Therefore, we find that the examiner has not established a prima facie case of obviousness of the invention as recited in 8Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
