The text of the original IPR declaration:

Original notice received November 8, 2000
Amended Notice received December 6, 2000
From: Gib Ritenour 

This is to advise the IETF that Nortel Networks has several patents (US
4,736,363, US 5,848,055, US 5,881,246, and US 5,995,503.) that it believes
may relate to MPLS technology.

Where there is a necessary dependence upon these patents in implementations
of MPLS, Nortel Networks hereby agrees to license on fair, reasonable, and
non-discriminatory terms to all parties, any patent claims it owns covering
such technology, solely to the extent such technology is essential to comply
with such standard, but on the condition that any such party grants to
Nortel Networks and its corporate affiliates a reciprocal license under such
party's patents for which there is also a necessary dependence.

Any questions related to this statement may be addressed to:
