Appeal No. 2006-3323
Application No. 10/287,151
Invention
Appellant’s invention relates generally to a method for
providing trip status information to a user (140) in transit from
a source location (110) to a destination location (120). First,
the user carries a mobile communication device (145) equipped
with a global positioning system that transmits to a remote
server a signal indicating the current location of the user in
transit. The remote server then estimates the time-of-arrival
bounds of the user to the targeted destination (120) based on the
received current location signal and other historical travel time
statistics pertaining to the same itinerary. The remote server
subsequently sends the estimated time-of-arrival bounds to the
user via the mobile communication device (145).
Claim 1 is representative of the claimed invention and is
reproduced as follows:
1. A method comprising:
(i) receiving a location of a mobile communications device
that is in transit to a destination;
(ii) estimating the time-of-arrival bounds for said mobile
communications device at said destination for a confidence

(a) said location, and
(b) at least one historical travel time statistic; and
