Appeal No. 1997-3853 Application No. 08/196,658 the damage to the signal is small. We disagree. Han states (column 4, lines 40-68) that when the counted value of input pulses is less than a set threshold value, the pseudo control signal is substituted. Although Han discloses that the threshold may be set slightly lower than normal, Han explains that the reason it may be lower than normal is because "damage to two or three control pulses does not substantially affect picture quality" (column 4, lines 52-53). Therefore, even if one were to interpret Han as allowing the original control signal to be used when damaged, the skilled artisan would find no need to compensate such a signal, since a damaged signal is used only when the amount of damage does not affect the quality of the picture. Furthermore, the examiner contends (Answer, page 4) that "Quintus provides sufficient motivation for using his gain control and amplification means of the range selection circuit and post-amplifier for the same purpose as in the instant invention: amplification for compensation for a weakened signal." We do not find in the references any motivation for combining Quintus with Han, and we are not persuaded by the rationale provided by the examiner. Quintus does not involve 5Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
