Title: Nokia's Statement about IPR Claimed in draft-trossen-simple-ondemand Received: November 17, 2003 From: harri.t.honkasalo@nokia.com This is to advise the IETF that Nokia has an unpublished US patent application No 10/602,078 that may relate to the Internet Draft submission: On-Demand Access Authorization for SIP Event Subscriptions . Regarding this Internet Draft submission simple/ondemand, to the extent this submission is included into final IETF standard spesification, Nokia agrees not to assert those claims in Nokia patents that apply to this submission and are technically necessary to implement the IETF standard spesification against any other party in respect of its implementation of the specification, provided that the party relying on this commitment does not assert its patents against Nokia. Regards, Harri Honkasalo Director of IPR, Standard Technology Nokia Corporation
