Nortel Networks Second Update to Nortel Networks Statement about IPR in RFC 3489
Date: 20 March 2008
From: Lee, Michelle

Dear Sir,

Please consider this a revised update to and replacement of Nortel
Networks Statement about IPR in RFC 3489 (ID#937). As identified in its
IPR disclosure ID#918, Nortel Networks Limited has an issued US patent
no. 6,993,595, entitled "Address Translation Change Identification",
that may be relevant to at least a portion of this proposed IETF RFC
3489
standard if approved and implemented:

Title: STUN - Simple Traversal of User Datagram Protocol (UDP) Through
Network Address Translators (NATs)
Tag: RFC 3489 http://www.ietf.org/rfc/rfc3489.txt?number=3489

If and to the extent claims of U.S. patent no. 6,993,595 cover and are
necessary to practice the resulting IETF RFC 3489 standard as approved,
further to Nortel Networks Statement IPR ID#918, Nortel Networks is
willing to make available licenses on fair, reasonable, reciprocal, and
non-discriminatory terms under such necessary claims of this patent for
compliance with the resulting approved IETF RFC 3489 standard.
