Pure guess: Certicom asserts that it has patents on this stuff.
I am not a cryptographer but I talked to Hilarie Orman and others about
some elliptical curve stuff at an IETF meeting. There was a disagreement
about whether Certicom patents left enough gaps to allow useful open
source code.
Here's a sample message that I got via google:
