Patents
The patent family spans Functional Coordinates, the Functional Coordinate System, Functional Location, Functional Space, Functional Proximity, Functional Trajectory, the Functional Information System, and Systems Syntax — the full mechanics of which are documented on the Coordinate System page and defined term-by-term in the Lexicon.
The full patent record
All 20 grants, in order of issue. Several late-family grants (the four “Syntactic tagging in a domain-specific context” patents, and the “Predictive search and navigation” continuations) extend a single earlier invention rather than claiming an unrelated one — see each patent’s Google Patents page for its full continuation history, filing date, and co-inventors.
