In some conversations here at IEEE 802 wireless interim, we have 'worked 
out' that the first patent deals with EC co-factors greater than 1. 
Although all of the curves we currently specify have a co-factor of 1, 
we do not state anything about the co-factor in the standard.

We only need to explicitly limit 5201-bis (and HIP-DEX) to curves with a 
co-factor of 1 and avoid the first patent.

Once we work out text on the co-factor, I guess I will send it to my old 
IPsec buddy, Tony Rosati, and see if it addresses their position (I 
understand other standards limit the co-factor to a value of 1).

We are still trying to figure out the others. I hope I can get help on 
working through them.
