contact with terminal 58, and in this state the driving power
to the motor is terminated. Next, when the capacitor 92 gets
charged to a critical voltage, a time period determined by the
timing circuit 110, and contact 56 touches terminal 60, the
power is applied to the motor for the duration of the dwell
period, until the capacitor is discharged and the contact 56
touches terminal 58 [col. 3, line 34 to col. 4, line 42]; and
the cycle repeats as long as the wiper system is in the
intermittent mode. Therefore, we sustain the anticipation
rejection of claim 1 by Riester.
With respect to claim 2, we further find that, in the
intermittent mode, the wipers are in the park mode when the
contact 56 is in contact with terminal 58 and capacitor 92 is
charging but has not reached the critical voltage. As stated
above, when the critical voltage is reached at capacitor 92
and contact 56 is at terminal 60, the wipers are withdrawn
from the parking state. The cycle repeats as discussed above.
Therefore, we sustain the anticipation rejection of claim 2 by
Riester.
Regarding claim 3, we agree with Appellant that Riester
does not disclose the limitation “containing no more than one
relay.” Riester does discuss that known intermittent dwell
