Lot Summary

With a 2006 priority date, the disclosed portfolio describes systems and methods related to routing,
data transmission reduction, advertising, and user interfaces. Some of the IP has wider application.
The patents pertain to “server-client” navigators, where some of functions of the navigator are
performed external to the navigation device. Extant technology in this class includes smartphone
navigators, connected car and telematics systems, personal navigation devices, autonomous
vehicles, and mapping web sites. This portfolio includes the following:

Abstract (US 7,831,386)
A navigation system and method uses loops as opposed to existing search techniques using line
segments to more expeditiously find routes on a map from a starting point to a destination. Roads
on a map are traced to form one or more continuous loops. Information regarding the loops is stored
for future reference. A starting point and at least one destination are specified, and loops that
connect the loops containing the starting point and destination are determined. A route is then
formulated from the starting point to the destination using road segments or intersections where
the identified loops are mutually contiguous. A list is generated including the loops and the road
segments associated therewith. The road segments of an initial loop are examined and, if a road
segment or intersection common to a next loop is identified, the road segments of that loop are
examined, and so on, until a route from the starting point to the destination is found. Alternatively
the route may be formulated by searching for routes along the roads that form one or more
continuous loops connecting the starting point and the destination. Various speed-up algorithms
and/or heuristics may be applied to the route formulation. The method finds application is many
fields of endeavor, including wireless client-server navigation; embedded/dedicated automotive
navigation, and logistics control, to name a few.

Abstract (US 8,116,974 & US 9,037,409)
A system and method are disclosed for conducting searches and generating routes to selected
points of interest using a wireless client-server (WCS) navigator. A method includes the step of
requesting, at a mobile unit, information about one or more locations meeting certain criteria.
Locations meeting the criteria are displayed on the display screen at the location of the user and, if a
location is selected, a route to include the selected location is automatically generated. Guidance
regarding how to travel to the selected location may also be provided. If the user is already en route
to a destination when a route to a selected location is requested, the navigator may generate a route
that includes both the original destination and the selected new location. If the user is already en
route to a destination when locations matching criteria are requested, along with the locations
displayed the navigator may provide information to the user as to the total travel time or distance of
a route passing through the original destination and a new location or the additional travel time or
distance in comparison to the original route. The method may further include the step of requesting
information about a class of locations such as restaurants.

Abstract (US 9,423,996)
Apparatus and methods are directed to the use and customization of user interfaces associated with
vehicle navigation systems, including “skins,” selection of context for clarification, and
autocompletion functions. The navigator may be a wireless client server navigation system
comprising mobile clients used for requesting and receiving guidance from a central server that
houses databases of geographical information. Customization may include images, icons, controls,
menus, colors, symbols, or shapes that are added, removed, or moved on the display. Options may
be selected using equipment external to the navigation system. If a word, or phrase is not
understood, the method proceeds with the steps of: searching a database for potential matching
letters, words, or phrases; querying the user with the potential matching words, or phrases; and, if
the user selects one of the potential matching words, or phrases: performing an operating associated
with the potential matching words, or phrases.

Representative Claims: US 7,831,386 – Claim #1
1. A navigation method, comprising the steps of: providing a map having a network of roads and
intersections; tracing the roads to form one or more continuous loops; specifying a starting point and
a destination on the map; graphing the map such that the loops are represented as nodes and
common roads or intersections between the loops are represented as edges; and using a greedy, A*,
SMA*, IDA*, or annealing search method on the graph to identify a set of one or more loops linked by
mutually contiguous roads and/or intersections such that a route can be traced from the starting
point to the destination along the roads and/or intersections comprising the identified loops.
