How can a patent be granted for
Standard industry practice for the last 20 years - For example the Livechart format that uses the exact same method for both proprietary cell/chart/map data and expanded to include S57 encoded data.
These methods are obvious to anyone knowledgeable in the art.
Another failing in the patent checking system for prior art or obvious work? Worse the applicant Chersoft must have known about prior art anyway!
- A method of communicating electronic map data to a remote vehicle, comprising a first data processing terminal interfaced with a vehicle-borne map data processing terminal over a network connection, the method performed at the first data processing terminal comprising the steps of;
compiling map data as at least one cell comprising a plurality of vector data records and a plurality of feature data records;
compressing the compiled cell data;
encrypting and digitally
signing the compressed cell data; and
transmitting the encrypted and digitally signed cell data over the network;
characterised in that the step of compiling comprises the further step of
reducing the respective bit length of a plurality of vector data values.
