Appeal No. 1997-1389
Application 08/642,811
The discussion of the first two paragraphs of column 5 of this
reference also indicate that the logic circuit 32 operates to
reduce or prevent the occurrence of shoot-through voltages
associated with respect to transistors 21 and 22. Thus, these
teachings clearly meet the end use limitation of the preamble
of claim 1 on appeal “for substantially eliminating shoot-
through current” to the extent this limitation breathes any
life or meaning into the body of claim 1 on appeal.
Attention is also directed to the Figure 8 embodiment
discussed at the middle of column 8 which shows a comparable
circuit to Figure 2 but utilizes instead a bootstrap bias
detector 71 connected to the midpoint of the transistors 21
and 22 at the output thereof, where the circuit 70 feeds
directly into the logic circuit 65, which circuit generally is
taught to control the switching transistors 21 and 22. The
enablement feature at the end of claim 1 is taught in the same
words at column 9, lines 22 through 26 with respect to Figure
8's more detailed showings in Figure 9.
In summary, we have sustained two of the three rejections
under 35 U.S.C. § 102 of claim 1 on appeal but have reversed
