description of task 270; note that average speed does
not apply at the start of the trip.) In some
embodiments, adjustments to the historical travel time
data might be made based on weather information,
traffic information, and average speed. The remaining
distance to the destination can be used for
interpolation, given that the travel time database
cannot have infinite spatial resolution. Time-of-
arrival metrics that might be estimated include:
expected time-of-arrival, earliest time-of-arrival,
time-of-arrival bounds for a given confidence interval,
etc. In some embodiments, the computations of task 245
might be performed at a remote server, while in other
embodiments, the computations of task 245 might be
performed by a processor embedded in mobile
communications device 145, as is well understood in the
art.
Thus, representative claim 1 does require estimating and
sending the time-of-arrival bounds for a confidence interval for
a user in transit from a source location to a destination
location.
Now, the question before us is what Schmier would have
taught to one of ordinary skill in the art? To answer this
question, we find the following facts:
1. At column 6, line 66 through column 7, line 6, Schmier
states the following:
[T]he present invention is embodied in a system and
method using global positioning system devices mounted in
individual vehicles which determine the precise
coordinate/location of the individual vehicles. That
information is transmitted to one or more central computers,
preferably via a wireless communication link, and more
generally via any of the available communications wireless
links or "hard-wired" links, including fiber optics links,
radio, satellite, microwave, cellular, telephone, etc., and
