FYI --
The official disclosure will probably be posted by the secretariat
shortly, but in the meantime I thought that the IPv6 WG should be
aware of this incoming IPR notification.

Dear Ms. Wasserman and Messrs. Townsley, Hinden and Haberman:
The Public Patent Foundation ("PUBPAT") formally notified IETF today
of the existence of intellectual property rights that may relate to
technology described in IETF documents. Specifically, U.S. Patent
No. 6,101,499 ("the '499 patent") owned by Microsoft Corporation may
relate to RFC 2462 - IPv6 Stateless Address Autoconfiguration and
RFC 2464 - Transmission of IPv6 Packets over Ethernet Networks
(collectively referred to as "IPv6"). A copy of the formal
notification appears below.
As stated in the notification, although others have disclosed the
'499 patent with respect to IPv4, its claims may also relate to
IPv6. For example, claims 1 and 30 could relate to the technology
described in RFC 2462. However, other than identifying this
potential relationship, PUBPAT takes no position regarding the
validity or scope of the '499 patent.
If PUBPAT can provide any further information or be of any other
assistance to IETF in its review of this matter, including perhaps
raising this issue with the entire IPv6 Working Group, should that
be desirable, please do not hesitate to contact me.
Sincerely,
Daniel B. Ravicher

Dear IETF:
Pursuant to IETF RFC 3979 Section 6.1.3, the Public Patent Foundation
("PUBPAT") hereby notifies IETF of the existence of intellectual
property rights that may relate to technology described in IETF
documents. Specifically, U.S. Patent No. 6,101,499 ("the '499 patent")
owned by Microsoft Corporation may relate to RFC 2462 - IPv6 Stateless
Address Autoconfiguration and RFC 2464 - Transmission of IPv6 Packets
over Ethernet Networks (collectively referred to as "IPv6").
Although IETF was previously notified of the '499 patent with respect to
IPv4 related documents (see
http://www.ietf.org/ietf/IPR/MICROSOFT-499.txt and
https://datatracker.ietf.org/public/ipr_detail_show.cgi?ipr_id=554), the
'499 patent's claims, including for example claims 1 and 30, could
possibly be read as also relating to IPv6. However, other than
identifying this potential relationship, PUBPAT takes no position
regarding the validity or scope of the '499 patent.
If we can provide any further information or be of any other assistance
to IETF in its review of this matter, please do not hesitate to contact me.
Sincerely,
Daniel B. Ravicher
