What's the fine print in this area? Does NIST have any PR blurbs covering
patents?
Common sense, politics, and patents makes for a horrible mess.
I think I'd be happy if the developing company got a head start. That could
be a reasonable trade for a lot of engineering/support during testing.
I think I'd be unhappy if they got a patent on a receiving technique that was
obvious to one skilled in the art (or whatever the magic patent phrase is)
after you looked at the description of the modulation/encoding technique.
That's assuming that NIST didn't get a broad free-to-use license for that
patent for listening to WWVB.
Another way to view this mess is the general topic of patents in standards.
WWVB isn't in the same class of "standards" as IETF/IEEE/ANSI/ISO type
documents, but given that it's a government monopoly, it's as good (or
better) than any other standard.
