Appeal No. 98-3299
Application 08/335,331
At the outset, we note the fundamental difference between
all the applied prior art and the invention as claimed. The
invention requires only a single sensor station which
establishes a line of bearing from the mobile transceiver to
the sensor station. Whereas the prior art employs other
sensor stations to generate other lines of bearing and use the
triangulation technique to determine the location of the
transceiver, the apparatus and the method claimed here use the
so called collateral information together with the single line
of bearing. Thus, the other sensor stations are not required.
All the independent claims have the limitations directed to
this difference. In claim 1, we note these limitations as “a
single ... processing unit for determining ... one ... line of
bearing from the single sensor station to the mobile
transceiver,” [lines 6 to 8]; and “a ... processing unit for
determining a probable position of the mobile transceiver ...
from (1) the line of bearing ... and (2) the collateral
information” [lines 11 to 14].
We have considered the rejections presented by the
Examiner under 35 U.S.C. § 102 over Hodson or Maloney or Gray
or Bunn or Kennedy. [Answer, pages 7 to 11]. We have
