'VI'. Licensing Declaration

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

This is to advise the IETF, in accordance with the IETF RFCs 3979 and 4879 that Nokia Corporation believes the Nokia patent application "Method of transmitting an acknowledgement to an A-subscriber” (09/571022) (the “Disclosed Patents”), may be required to implement the following IETF contribution ” RFC 3665” (the “Contribution”).

To the extent that the Contribution is incorporated in an IETF RFC, Nokia Corporation informs that Nokia Corporation and its Affiliates will make a license available on fair, reasonable and non-discriminatory (“FRAND”) terms and conditions based on reciprocity to all persons desiring to implement such IETF RFC for those claims of the Disclosed Patents only that would, in the absence of a license, be necessarily infringed by the use of a right (e.g. making, using, selling, importing, distribution, copying,etc) with respect to a technology implementing such IETF RFC (the “License”). In this context, “necessarily infringed” means that such claims are technically necessary to implement the IETF RFC in question.

“Affiliate” of Nokia Corporation means any legal entity that is for the time being directly or indirectly controlled by Nokia Corporation. Notwithstanding the foregoing Nokia Siemens Networks B.V (the joint venture of Nokia Corporation and Siemens AG) and the companies controlled by Nokia Siemens network B.V shall not be deemed to be Affiliates of Nokia Corporation. Control in this context, exists where one entity owns more than fifty percent (50%) of the voting stock or equity in another entity, or regardless of stock or equity ownership, is otherwise able to direct its affairs or to appoint a majority of the members of the board of directors or an equivalent body to determine the course of action of the entity by virtue of its voting or other rights. Such entities shall only be deemed to be Affiliates hereunder for as long as such control exists.

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.
