Notice of IPR

[Geoff Huston <gih@apnic.net>]

An IPR disclosure that pertains to the Internet-Draft entitled "Hash 
Based Addresses (HBA)" (draft-ietf-shim6-hba) was submitted to the 
IETF Secretariat on 2006-11-09 and has been posted on the "IETF Page 
of Intellectual Property Rights Disclosures" 
(https://datatracker.ietf.org/public/ipr_list.cgi). The title of the 
IPR disclosure is "Microsoft's Statement about IPR claimed in 
draft-ietf-shim6-hba-01." Its Claim Number 762, in the section 
"Specific IPR Disclosures", submitted on the 9th November.

The disclosure has ticked the box:

Royalty-Free, Reasonable, and Non-Discriminatory License to All Implementers.

and  also ticked:

This licensing declaration is limited solely to standards-track IETF documents.

Section 8 of RFC3979 states:

  "In general, IETF working groups prefer technologies with no known 
IPR claims or, for technologies with claims against them, an offer of 
royalty-free licensing.  But IETF working groups have the discretion 
to adopt technology with a commitment of fair and non-discriminatory 
terms, or even with no licensing commitment, if they feel that this 
technology is superior enough to alternatives with fewer IPR claims 
or free licensing to outweigh the potential cost of the licenses.


Are there any comments about the viability of HBA approach in the 
light of this, or do WG members think that the royalty-Free 
Non-Discriminatory terms are acceptable in this case?
