Appeal No. 96-1460
Application 07/882,811
defining a digital map further defining a number of layers,
each of which has various zones corresponding to a rate of
application of a product at a plurality of global positions
within the zone. Finally, at the end of each claim there is
recited the determination of the current position of the
vehicle corresponding to one of these previously recited
plurality of global positions within each zone.
The examiner’s reliance upon col. 2, lines 55 to 59 of
Hanson to provide a basis for all of these navigation features
is misplaced since we find that the reference does not
disclose or otherwise anticipate all of these features as
referenced in each of independent claims 1 and 13 on appeal.
We recognize as do appellants that every point of a given
field has inherently some associated global coordinates such
as latitude and longitude associated with it. However, there
is no evidence before us that Hanson necessarily, in the sense
of inherency as apparently argued by the examiner, teaches the
associated global coordinates and global positions in his
system as recited in these claims on appeal. Hanson’s system
uses a dead reckoning-type navigation system. The examiner’s
reasoning also appears to bridge over into reasoning
