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):

Licensing 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 "Access right control using access control alerts ” (10/353014) (the “Disclosed Patents”), may be required to implement the following IETF contribution ”RFC 4575, A Session Initiation Protocol (SIP) Event Package for Conference State” (the “Contribution”).

To the extent that the Contribution is incorprorated 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.

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.
