History for IPR disclosure
Brocade Communication Systems' General IPR Statement

From: http://www.ietf.org/ietf-ftp/IPR/Brocade.txt

Hardcopy letter dated May 10, 2002
From: Brocade Communications Systems, Inc.
1745 Technology Drive
San Jose, CA 95110



This letter sets forth Brocade's patent licensing policy regarding any
IETF Standard, current or future. Brocade is not willing to waive its
rigts in its relevant, essential patent and patent applications
(collectively "IPR"). However, in accordance with RFC 2026, Brocade is
willing to negotiate licenses for its IPR on reasonable and
nondiscriminatory terms and conditions. In particular, Brocade is willing
to negotiate nonexclusive, worldwide licenses under its IPR to allow the
manufacture, use, sale, offer for sale and importation of the portions of
any product that implement and are compliant with all relevant portions of
the standard; provided that these licenses may not extend to any part of
function of a product that is not required to implement or comply with the
standard.

Brocade's license grant may be conditioned upon the licensee's grant of a
reciprocal license under the licensee's IPR and IPR owned by parties with
which licensee is affiliated. In assessing what terms are reasonable,
Brocade may refer to the royalty rates that a potential licensee has set
for its own IPR and IPR of parties with which it may be affiliated.
Brocade also reserves the right to grant licenses to its IPR as part of a
cross-license with any other party.

Brocade has not performed a search of its patent portfolio for the purpose
of determining whether Brocade has any IPR to any existing or pending IETF
standard. With this letter, Brocade submits there is no futher obligation
to search its patent portfolio for future standards.

Please contact me at 408-392-5225 concening any licensing  matters.

Sincerely,

Brocade Communications Systems, Inc.
