Here's the official statement from Ridgeway Systems & Software with regards
to intellectual property claims on methods for the traversal of non-protocol
awarefirewalls and NATs for session-oriented protocols such as SIP and H.323,
(currently draft-davies-fw-nat-traversal-00.txt), which you may put on the
IETF IPR page as you deem appropriate:

"Ridgeway Systems & Software has applied for one or more patents on
technology related to the traversal of firewalls and NATs for session-oriented
protocols such as SIP, H.323, H.246, MGCP and FTP.

If any patents issued to Ridgeway are required to implement a standard for
the traversal of firewalls and NATs, Ridgeway intends to disclose those patents
and license them under openly specified, fair and non-discriminatory terms."
