Still not FOSS compatible as the patent grant is only for implementations of the specification. It is still a pretty generous grant without other caveats though

Still not FOSS compatible as the patent grant is only for implementations of the specification. It is still a pretty generous grant without other caveats though. The patent "racket" is the system enshrined in the current laws which I agree need fixing but our wishes for that to happen don't make it so and the patents won't disappear unless it does or until they expire.
