Appeal No. 2000-1743
Application No. 09/314,618
Bouda patent that the 1-2 shift valve (63) is maintained in a
downshifted position (1st gear) when there is little or no
fluid pressure being applied to line (102a) or to the right-
hand end of the valve as seen in Figure 1B (i.e., when the
solenoid valve 51 is deenergized and the fluid exits at drain
line 105). When the solenoid valve (51) is energized it
closes drain line (105) and produces pilot pressure in the
line (102, 102a) to move the shift valve (63) from its right
position to its left position to thereby effect shift
operations (i.e., to allow an upshift of the transmission from
1st gear to 2nd gear). In this regard, the method as
disclosed in Bouda is completely different than that set forth
in appellant's claim 1 on appeal.
As for the means for urging the 1-2 shift valve into an
upshifted position as set forth in appellant's claim 3 and the
method step therein, we again note that the operation of the
transmission in Bouda regarding the 1-2 shift valve is
entirely different than that required in appellant's claim 3
on appeal. See pages 3-5 of appellant's reply brief for the
detailed reasoning. For similar reasons, we also agree with
