You can't add it to the _standard_ because of restrictive licensing. I
guess Informational RFCs are possible, but they don't make me happy -
essentially the WG is doing free work, both technical and marketing, for
the owner(s) of the patents.
IIRC, not all ECC stuff is patented, only curves over GF(q), q even, which can
be implemented efficiently using two-valued logic.
The rule of thumb for ECC is something like "ECC curves are divided into three
groups, weak curves, inefficient curves, and curves patented by Certicom".
