The Patent Holder states that its position with respect to licensing any patent claims contained in the patent(s) or patent application(s) disclosed above that would necessarily be infringed by implementation of the technology required by the relevant IETF specification ("Necessary Patent Claims"), for the purpose of implementing such specification, is as follows(select one licensing declaration option only):

See Text Below for Licensing Declaration
Licensing information, comments, notes, or URL for further information

IBM will, upon written request, provide a nonexclusive patent license, with
other reasonable and nondiscriminatory terms and conditions, for those
patents issued to IBM which contain claims related to compliant
implementations of the referenced RFC's / Internet Drafts and for which IBM
is able to provide patent licenses (including the patents disclosed above).
This patent license is available to all entities. If a party requesting a
patent license also has claims related to the implementation of the
Specifications, IBM will grant patent licenses only if the recipient, in
return, will grant IBM a reciprocal license, with substantially identical
terms and conditions, under the Requestorâ€(tm)s Claims.

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.
