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

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.
