This declaration is being made pursuant to the provisions of IETF IPR
Policy, Sections 10.3.1 and 10.3.2.

This is to advise the IETF that AT&T believes it owns intellectual property
that may relate to Internet Draft document " draft-rosen-rfc2547bis-03.txt",
including United States Patent No. 6,081,524.  To the extent that the
technology discussed in this Internet Draft becomes an IETF Standard, and to
the extent claims of AT&T's patents are required to implement the IETF
Standard, AT&T agrees that, upon written request, AT&T will offer, on a
nondiscriminatory basis, non-exclusive licenses on fair and reasonable terms
under such patent claims to implement that IETF Standard. AT&T's willingness
to grant such licenses is conditioned upon the prospective licensee granting
a reciprocal license to AT&T under any patents that the prospective licensee
has to any technology required to implement that IETF Standard.


Written requests for licenses may be sent to:
