Determining authorized use of a software application

A processing device for validating a software application installed on a remote processing device, the processing device comprising:

• at least one processor;
• a memory including instructions for the at least one processor;
• and
• a communication interface connecting the at least one processor with the memory, the memory including:
• instructions for receiving a product identifier from the remote processing device via a network,
• instructions for determining a location of the remote processing device,
• instructions for accessing a set of rules with respect to a geographic restriction on use of the installed software application, the set of rules including geographic restrictions on use of the installed software application with respect to a plurality of geographic subdivisions, at least one geographic subdivision being a subset of another geographic subdivision,
• instructions for mapping the location of the remote processing device to the set of rules to determine whether use of the software application is permitted at the location of the remote processing device,
• instructions for determining whether the remote processing device is associated with an entity, and
• instructions for determining whether the software application installed on the remote processing device violates a license agreement of the entity for use of the software application.

A tangible machine-readable medium having instructions recorded thereon for at least one processor, the tangible machine-readable medium comprising:

• instructions for receiving from a processing device a product identifier identifying a software application installed on the processing device;
• instructions for determining a location of the processing device based on at least a portion of a network address of a network gateway used by the processing device to access a network;
• instructions for accessing a set of rules with respect to a geographic restriction on use of the installed software application, the set of rules including geographic restrictions on use of the installed software application with respect to a plurality of geographic subdivisions, at least one geographic subdivision being a subset of another geographic subdivision;
• instructions for mapping the location of the processing device to the set of rules to determine whether use of the software application is permitted at the location of the processing device;
• and
• instructions for providing a response to the processing device to enable a plurality of features of the installed software application when the mapping of the location of the processing device to the set of rules determines that use of the software application is permitted at the location of the processing device.
