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

If the SCVP draft (ietf-pkix-scvp-18) is adopted as a standard by IETF, and
any claim in any of the Patents is necessary for implementing such standard,
CoreStreet will negotiate licenses of the Patents on reasonable and
nondiscriminatory terms and conditions for at least any part or function of
a product or service that is technically necessary for compliance with such
standard. CoreStreet's willingness to grant such license(s) is conditioned
upon the prospective licensee paying reasonable royalties and granting a
reciprocal license to CoreStreet (and its successors) of its applicable
patent rights. Except as provided above, CoreStreet reserves its rights in
its intellectual property.

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.

Additional notes

This letter describes CoreStreet's position with respect to the current IETF
IPR Policy, and provides a disclosure concerning CoreStreet patents that
relate to the subject matter of the current SCVP draft
(http://www.ietf.org/internet-drafts/draft-ietf-pkix-scvp-18.txt).

CoreStreet understands the IETF's IPR Policy to require disclosures of
intellectual property rights that are necessarily infringed by
implementation of a standard with respect to which a person is contributing;
in our case, SCVP. CoreStreet believes an implementation of the SCVP
standard (as currently drafted) need not necessarily infringe our patents
and, for this and other reasons, believes no disclosure of our patents has
been or is required.
