If the NSA paid anything significant for any of the
curves, we would be told. Therefore the NSA paid
nothing or almost nothing, and therefore if the NSA
licensed anything, it would have licensed everything.
I doubt that the NSA paid any money whatsoever for this
license, making it profoundly unimpressive as evidence
that *any* curves have a plausible valid patent. If the
NSA paid real money, the patent holders would be
sticking it in our face as a price setting precedent.
