Requirements for a patent
Not obvious: Which often boils down to "not done before" (which isn't the same but there you go)
Inventive : A requirement so rarely met, is it really a requirement anymore?
Utility: Must be useful (in its own right, not as a legal tool for bashing the competition!)
Embodiment: Somebody skilled-in-the-art must be able to read the patent and use it to build a device that does the useful thing.
The patent referred to has lots of "may this", "might that", "one could try this" and so on but doesn't seem to say "do this to achieve the useful thing in a manner a skilled-in-prior-art person would not have thought of" and so the requirements look a tad sketchy IMHO.
