of a noise-related signal in an energy signal. Nevertheless, the
examiner’s position at page 12 of the answer is that,
Fukuoka uses a comparator to get an Vout which is equal
to Vin, if a different voltage is produced (noise-related
signal is detected), the Vg is inputted to the comparator
until the Vout is equal to the Vin (col. 5, lines 20-40), so,
the unwanted different voltages (noise-related signal or
crosstalk) is not produced in the display panel.
We are not persuaded by the examiner’s position. With
respect to Figure 1 of Fukuoka, V would be the energy signal
OUT
applied to a pixel of claim 58. However, Fukuoka does not detect
a noise-related signal in the energy signal and, accordingly,
discloses no means for modifying the energy signal in response to
detection of a noise-related signal. Although Fukuoka modifies
V , it is in response to V , which is neither a noise-relatedOUT G
signal nor in the energy signal.
We will not sustain the rejection of dependent claims 12 and
48 as obvious over Fukuoka or of dependent claims 39-42 as obvious
over Fukuoka and Kanayama. We do not agree with the examiner that
the feedback line of Fukuoka is a current mirror circuit. A
current mirror circuit includes at least two outputs providing
output currents. Fukuoka’s feedback line has but one circuit line
which could be considered as providing a current output.
Furthermore, appellants disclose at page 16, lines 23 and 24, of
