Re: Possible patents pending Claim on ECDSA

This is to advise the IETF that Certicom believes it has patents pending that 
relate to ECDSA, namely point compression, public key validation (including 
domain parameter validation), and computational techniques. In accordance with 
the intellectual property rights procedures of the IETF standards process, 
assuming the relevant patents are granted, Certicom is willing to offer, upon 
written requests from the implementers of the ECDSA, a non-exclusive license 
under reasonable and non-discriminatory terms and conditions, providing the 
applicant provides a similar grant for the applicant's relevant patents (if 
any) and respects Certicom's other intellectual property.

Any party wishing to request a license should contact:
