station . . . analyzing the instantaneous positions of said first and second mobile tracking
stations and the bearing information transmitted from said first and second mobile tracking
stations thereby to ascertain by triangulation the exact position of said target.”
We find that the combination of Reagan, Fraughton and Angeloni fails to teach or
suggest a tracking system where each mobile tracking station determines it’s position,
determines the bearing of the target relative to the mobile tracking station and transmits
the bearing and position information, wherein the bearing and position information is used
to locate the target. We find that Reagan teaches a system where there are mobile
tracking stations which determine the direction of the target relative to the mobile tracking
station. See column 2, line 26 to 29. Further, we find that Reagan teaches that the system
may employ triangulation. See column 2, lines 22 through 25. However, we find that
Reagan fails to teach that the position of the mobile tracking stations is determined or that
the position of the tracking station and the bearing of the target are transmitted. Further,
we find that Reagan does not teach or suggest how to perform triangulation.
We find that Angeloni teaches a system for locating a vehicle by using triangulation
based upon bearing information received from stationary tracking stations.
See column 2, lines 15 through 29. We find that Angeloni fails to teach determining the
positions of the stationary tracking stations. Further, we find that Angeloni fails to suggest
