History for IPR disclosure
Lucent's Patent Statement pertaining to SRP in general, and RFC2945 specifically

From: http://www.ietf.org/ietf-ftp/IPR/LUCENT-SRP

Received March 28, 2002
From: "Carter, William Robert (Bill)"


It has come to our attention that misunderstandings may exist concerning
Lucent's willingness to license patents that are essential to the Secure
Remote Password specification ("SRP") from Stanford University which has
been submitted to the IETF and has been approved by the IETF as a standards
track RFC, namely RFC 2945.

To avoid any further misunderstandings, going forward we would like to state
the following:

Lucent has not conducted and has no current plans to conduct a search of
its patent portfolio with respect to SRP.  In addition, Lucent has not studied
and has no current plans to study its patents with respect to SRP.

However, in the event that any Lucent patents are determined to be
essential to the implementation of SRP as an IETF standards track specification,
Lucent is prepared to grant - on the basis of reciprocity (grantback) - a
license to those patents on reasonable and non-discriminatory terms.

We sincerely regret any misunderstandings, and hope that the foregoing
statement will alleviate concerns about Lucent's commitment to licensing its
patents in connection with SRP.

As you are aware, RFC 2945 was neither submitted or proposed by Lucent.
Therefore, Lucent's general patent statement to IETF in 1999 does not cover
RFC 2945.

Lucent may have patent claims that are essential to RFC 2945.  But that
would have to be verified by a careful review of our patent portfolio.  Such
a search has not been conducted.  Because of the present strain on our
resources, it is unlikely that a search will be conducted.  However, if the
IETF has particular concerns about one or two patents that could impact RFC
2945, we would welcome your identification of those patents and your
comments on those issues so that we could review the particular patents in
light of RFC 2945.

Sincerely,
