Re: [Hipsec] Fwd: IPR Disclosure: Certicom Corp's Statement of IPR Related todraft-ietf-hip-rfc5201-bis-05

Hi Bob,

following up on this old IPR disclosure, even though the spec now
mandates a co-factor of 1, I have not seen any updated to the IPR
disclosure. Do you know anything else about this? What about the other
two patents referenced in the disclosure?

Thanks,

Gonzalo
