Appeal No. 1997-1317
Application No. 08/371,995
radio signal reflected from said target.
[Emphasis added.]
Appellant's next argument relative to claim 1 is
that Strauch further points out in column 2, lines 3-7, that
the system described in the U.K. patent specifications
"generates a sawtooth transmission frequency having a fixed
modulation slope and consequently operates according to a
different principle than the device according to the
invention" (Brief at 14). This argument is not understood,
because appellant has not explained why claim 1 precludes
variation of the slope, as occurs in Strauch's device,
wherein the modulation slope of the transmitted frequency
varies as a function of the range (col. 2, lines 7-9).
Appellant also argues that "Strauch mandates (column
4) divider 10 as a necessity, for that device to work, for
cancelling drifts in the two inputs of the mixer, which leads
away from the simple device proposed in the present invention"
(Brief at 14). This argument fails because appellant has not
explained why claim 1 precludes the presence of such a
divider.
