This is to advise the IETF that Nortel Networks has patents and/or
patent applications that may be considered essential to RFC 3525,
Gateway Control Protocol (rfc3525.txt),
before the Megaco Working Group.  Specifically:

      6,385,196 / US, Communication System Architecture and a Management Control
      Agent and Operating Protocol Therefore
      742,135 / AU, Communication System Architecture and a Management Control
      Agent and Operating Protocol Therefore
      99/31926 / WO, Communication System Architecture and a Management Control
      Agent and Operating Protocol Therefore
      1 040 703 / EP, Communication System Architecture and a Management Control
      Agent and Operating Protocol Therefore

Where there is a necessary dependence upon such patents and/or patent applications in
implementing this or other IETF standards document of the Megaco Working Group, Nortel
Networks is willing to make available non-exclusive licenses on fair, reasonable,
reciprocal, and non-discriminatory terms and conditions, to such patent rights it owns,
solely to the extent such rights are essential to comply with such IETF standard.
