Appeal No. 1996-3126
Application No. 08/300,586
Accordingly, we cannot sustain the rejection of claims 2 and
22 over Krauss.
As explained above, neither Sokal nor Krauss has a
varactor capacitance. Therefore, Sokal and Krauss clearly do
not include a substantial varactor capacitance as recited in
claims 3 and 23. Accordingly, we cannot sustain the
anticipation rejection of claims 3 and 23 over Sokal nor
Krauss.
Claims 5 and 25 recite a voltage immediately prior to the
switch's turning on equal to about 50% of the supply voltage.
Sokal shows in Figure 4A a peak voltage of 3.47 V - 2.47 V .cc CE
A graphical calculation of V shows that the voltage step just
cc
before turn-on of the switch is approximately 50% of the
supply voltage V . Similarly, Figure 14-8 of Krauss would
cc
appear to have a voltage at turn-on of the switch at about 50%
of the supply voltage. However, neither reference indicates
what type of scale is used for the vertical axis of the graph.
As appellants assert (Reply Brief, page 6) that "[i]t is not
uncommon for voltage and current waveforms to be plotted on
semi-log graphs rather than on a linear-linear scale," we find
that the value of the voltage step relative to the supply
