This is to advise the IETF that AT&T believes it owns at least one patent
that may relate to Internet Draft document "draft-mogul-http-delta-07.txt",

technology discussed in that Internet Draft becomes an IETF Standard and to

Standard, AT&T agrees that, upon written request, AT&T will offer, on a
nondiscriminatory basis, non-exclusive, royalty-free licenses 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.
