I've just noticed that Nortel has recently been issued a patent for 
which they have made an IPR disclosure relative to RFC 3428, the SIP 
MESSAGE method.

The disclosure document is listed at:

http://www.ietf.org/ietf/IPR/nortel-ipr-rfc-3428.txt

The issued patent is US patent number 6,757,732

and you can retrieve its full text from:
