The following was reported by a member of the Public-Key Infrastructure
(X.509) Working Group. Note that no official notification as been
received by the IETF Secretariat

RSA Data Security, Inc. has provided the following statement with
regard to this patent:

It is our understanding that the proposed PKIX Certificate Profile
(PKIX-1) standard currently under review contemplates the use of
U.S Patent 4,405,829 entitled "Cryptographic Communication System
and Method" (the "RSA patent") which patent is controlled by RSA.

It is RSA's business practice to make licenses to its patents
available on reasonable and nondiscriminatory terms. Accordingly,
if the foregoing identified IETF standard is adopted, RSA is willing,
upon request, to grant non-exclusive licenses to such patent
on reasonable and non-discriminatory terms and conditions to those
who respect RSA's intellectual property rights and subject to
RSA's then current royalty rate for the patent licensed. The royalty
rate for the RSA patent is presently set at 2% of the
licensee's selling price for each product covered by the patent.
Any requests for license information may be directed to:

Director of Licensing
RSA Data Security, Inc.

Redwood City, CA 94065

A license under RSA's patent(s) does not include any rights to
know-how or other technical information or license under other
intellectual property rights. Such license does not extend to any
activities which constitute infringement or inducement thereto. A
licensee shall make his own determination as to whether a license
is necessary under patents of others.

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.
