Nortel Networks Statement on IPR claimed in draft-ietf-ccamp-loose-path-reopt-00.txt

["Adrian Farrel" <adrian@olddog.co.uk>]

Dear Richard and Michelle,
 
Thank you for submitting your Patent Disclosure

(http://www.ietf.org/ietf/IPR/nortel-ipr-draft-ietf-ccamp-loose-path-reopt-00.txt)

with respect to IETF Internet Draft draft-ietf-ccamp-loose-path-reopt-00.txt.
 
I would be grateful if you could clarify two points to help me understand this discolsure further.

1. The disclosure states that:
     Nortel Networks U.S. Patent No. 6,560,654 entitled "Apparatus and
     method of maintaining timely topology data within a link state routing
     network" may contain claims that may be necessary for practicing a
     resulting IETF Standard based on this Internet Draft.
  Could you provide more detail about what aspects of
  draft-ietf-ccamp-loose-path-reopt-00.txt you believe may be impacted by
  this disclosure?
 
2. Can you clarify whether the "fair, reasonable, reciprocal, and
   non-discriminatory terms" referenced in the disclosure include the
   intention, in the event that the referenced draft becomes an Internet
   Standard, not to assert the patent except that some party asserts a patent
   patent it owns or controls against Nortel?

   By way of an example of wording that covers this intention, can I draw

   your attention to a completely unrelated IPR disclosure at
   http://www.ietf.org/ietf/IPR/cisco-ipr-draft-ietf-tcpm-tcpsecure.txt
 
Thank you for any clarification you are able to offer.

 

Please note that I am copying this email to Kireeti Kompella who co-chairs the IETF's CCAMP working group with me. The CCAMP working group developed the Internet-Draft in question (draft-ietf-ccamp-loose-path-reopt-00.txt) and so I am also copying this email to the CCAMP mailing list.

 

Best regards,

Adrian Farrel
