[Cryptography] What is the state of patents on elliptic curve cryptography?

[Phillip Hallam-Baker]

It is almost certain that most uses of EC would not infringe the remaining
patents.

But the patent holder can force anyone attempting to use them to spend
about $3-5 million to defend their right to use EC and so there is very
little incentive to do so given that RSA 2048 is sufficient for almost any
need.


The situation might change depending on who buys RIM.
