Pekka,
Thanks! That answers the question I had (i.e., you believe the 
legal
issues are resolved).

As further clarification, here is the US patent office
transaction history for the SRI application, which shows
that the application was rejected on 8/02/04:

I think I can clear this up. The patent office rejected
SRI's patent application, therefore there are no valid
claims that could prevent ISATAP from being included
in public domain software releases. Indeed, Microsoft,
cisco, and FreeBSD/KAME are shipping ISATAP and have
been doing so for a long time, and I believe there are
also several others.

Pekka,
   I'm not assuming hidden agendas here; I simply don't know what
they mean by "no license for implementers."  It doesn't say they
relinquish *all* licensing, which would be clearer if that's what they
mean. If implementers, distributors, and users are included, then
who's left that does need licensing? If that answer really is nobody,
then why bother with "for implementers."?
   So, I don't think it's a hidden agenda, I think they said what
they mean. I just don't know what they mean. :-)


If you look at the page they used to file the disclosure:

https://datatracker.ietf.org/ipr/new-specific/

You'll notice that they chose the most relaxed option available, and 
all the options only discuss implementers not distributors.


Now, if you look at the background commentary of the subject:

http://tools.ietf.org/html/rfc3905

.. the comment about that particular option is:

   a) No License Required for Implementers: The Patent Holder does not
  require parties to acquire any license to its Necessary Patent
  Claims in order to make, have made, use, import, offer to sell,
  sell, or distribute technology that implements such an IETF
  specification.

Seems clear to me, though someone could argue whether RFC 3905 is 
normative in this context, i.e., whether the person who submitted the 
disclosure understood the comment quoted above and that that's the way 
"no license required for implementers" must be interpreted.

I guess license is no longer required for implementers of ISATAP.
Is it right, Fred?

https://datatracker.ietf.org/ipr/550/


Does this also allow license-free redistribution?

I'm certainly no lawyer, but I don't see the point of
having a patent that doesn't restrict *something*. :-)


DavidS, the history here is that first the IPR holder did not grant 
license-free implementation.  After considerable time (and I suspect 
energy spent by Fred), the company was convinced that license-free 
implementation did not hurt their interests and they were willing to 
give it away on this specific instance.  I'm not sure if you should 
attribute to hidden agendas what you can explain by "doing the right 
thing" (granted, very few companies do this which may make it suspect, 
but still..).


That is my interpretation as well.  It allows license free 
implementation, but not distribution of said implementation.


This may be a fine point.  When submitting the IPR notice, the IPR 
holder is asked whether it can be implemented without a license.  No 
questions about redistribution are asked -- maybe nobody thought that 
asking that would be necessary if a positive answer is received on the 
first one.  I'd guess that the owner that grants license-free 
implementation would also be fine with license-free (re-)distribution.

Last I heard, there are Intellectual Property claims with ISATAP,
which is why the RFC is not standards track and which makes it
effectively a proprietary protocol.

Unless that's been resolved, I think the claim by the IP owner is
that it can't be distributed without a license from them. So, maybe
not worth the effort for an experimental RFC.

[PATCH 00/05] ipv6: RFC4214 Support

2007-11-06 Thread Templin, Fred L
From: Fred L. Templin <[EMAIL PROTECTED]>

The following diffs are specific to the Linux 2.6.23
kernel distribution and implement RFC4214 (Intra-Site
Automatic Tunnel Addressing Protocol - ISATAP). The
affected modules are:

  linux2.6.23/include/linux/if.h
  linux2.6.23/include/net/addrconf.h
  linux2.6.23/net/ipv6/addrconf.c
  linux2.6.23/net/ipv6/sit.c
  linux2.6.23/net/ipv6/Kconfig

and the diffs for each file are included in the following
messages as [PATCH 01/05] through [PATCH 05/05].

The code has been tested under Fedora Core 6 running the
modified 2.6.23 and has been verified in both ISATAP
client and ISATAP router configurations. (The ISATAP
router configuration uses the 'radvd' package.)
Interoperability testing with Windows Vista has also
been performed.

Please advise as to next steps.
