Application No. 09/814,054
a present position mark 61, to the destination, as indicated by a destination
mark 62. The map display panel 60 is provided with, as input means: a
route change key 64 for changing the entire route indicated, namely, for
commanding a re-search; a route information key 65 for calling up a route
information screen 7; and a guide start key 66 for starting navigation along
the displayed route.
A route information screen 7, as shown in FIG. 7(b), is opened by
pushing the route information key 65 in the entire route map screen 6 of
FIG. (7a), and lists the road names and the branching point names on the
route ahead of the present position. For the route display, a branching
point mark 72 is shown as lying ahead of a present position mark 71 toward
the destination, and a road is indicated at 73 by parallel lines together with
distances 74 in between.
2. Ohmura states in the abstract of the invention that:
A vehicle navigation system for guiding a vehicle to a preselected
destination by continually communicating the heading direction to be
followed regardless of any detours away from a direct heading. In one
embodiment, a two phase system is provided to initially guide the vehicle to
a zonal area containing the destination, and in the second phase, guiding the
vehicle, by communicating local information, directly to a specific
destination within said zonal area. The system can employ bar coded signs
being read by a remote reader on the vehicle to obtain detailed information
concerning the vehicle location, the streets-roads in the vicinity of each sign,
traffic control information; parking and fuel availability, and specific street-
road address information.
With the above discussion in mind, we find that the Asano-Ohmura combination
teaches away from the claimed invention. First, Asano’s teaching violates the requirements
set forth in the claim limitation. Asano teaches, as depicted in figure 4, displaying two
markings corresponding to the present position of the vehicle and the selected destination.
Asano also teaches displaying a routing path interconnecting the position of the vehicle
and the selected destination. The claimed invention, in contrast, expressly requires that
only the present location of the vehicle and the selected destination be displayed without
showing any routing path interconnecting them. Such a violation of the claim limitation
