V. Licensing Declaration

The Patent Holder states that its position with respect to licensing any patent claims contained in the patent(s) or patent application(s) disclosed above that would necessarily be infringed by implementation of the technology required by the relevant IETF specification ("Necessary Patent Claims"), for the purpose of implementing such specification, is as follows(select one licensing declaration option only):

Licensing See Text Below for Licensing Declaration
Licensing information, comments, notes, or URL for further information

Certicom will, upon request, provide a nonexclusive, royalty free patent license, to
manufacturers to permit end users (including both client and server sides), to use the
patents in schedule A when implementing any of these protocols, including those
requiring third party certificates provided the certificate is obtained from a licensed
Certificate Authority (CA).

It is important to clarify the situation stated in the preceding paragraph regarding
certificates. If a CA creates certificates that use Certicom intellectual property then
Certicom would expect this entity to obtain license from Certicom, which will be granted on reasonable and non-discriminatory terms. Certificates acquired from a licensed CA
may then be used in any of the above protocols on a royalty free basis, i.e. without further
payment to Certicom.

The reasonable terms and conditions of this license, are contained in the license
document that Certicom intends to make available on its web site.

This royalty free license is restricted to the use of the protocols listed above utilizing the
ECC options in the specified drafts and restricted to NIST curves P256, P384, and P521
only. The IKE and IKEv2 protocols must be used in combination with IPSec in this
license grant. The above list of protocols will be amended from time to time in order to
keep the documents current.

The license granted does not extend, either explicitly or implicitly, to other IETF
protocols.

Should those end users requesting this royalty free patent license also have patents
containing claims that are necessary and essential in the implementation of the above
protocols, Certicom’s grant of the royalty free license will be conditioned upon the grant
to Certicom of a reciprocal license under such end user’s necessary and essential
claim(s).

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
