Carlos,
I can only comment on the second document listed in the third-party IPR
disclosure (http://www.google.com/patents/WO2016039798A1#npl-citations). I have
not been aware of the first one. Regarding the second patent application, I am
a bit confused by the intent of this IPR disclosure.
To add some context: There is a publication, and actually that text may be
easier to read:
Michael Scharf, Gordon T. Wilfong, Lisa Zhang: "Sparsifying network
topologies for application guidance", Proceedings of IFIP/IEEE IM 2015, May
2015, pages 234-242 (http://dl.ifip.org/db/conf/im/im2015/135438.pdf)
That paper refers to draft-ietf-alto-deployments at various places to explain
the background of ALTO (reference [4]). So, it is not surprise that
draft-ietf-alto-deployments is cited in the patent application. I am not a
lawyer. However, if I had assumed that an action according to RFC 3979 is
required in this situation, an IPR disclosure would obviously have been
submitted.
In general, draft-ietf-alto-deployments is a long informational document that
surveys quite a number of use cases and technologies. Given that widely used
technologies such as CDN optimization and methods to obtain dynamic
connected-network topology via nodes are mentioned, it would be a huge surprise
to me there was no other IPR "somehow" related to some wording in
draft-ietf-alto-deployments, including e.g. IPR owned by Cisco Technology, Inc.
However, I am not sure what value IPR disclosures have for such an
informational document that does not give normative guidance.
Regarding the process, I am actually surprised that a patent search has been
performed as part of an OPS-DIR review, given e.g. what is written in RFC 5706
Appendix A. And I think the wording of RFC 3979 Section 6.1.3 is that a third
party IPR disclosure is "encouraged". So far I have assumed that this wording
does not imply "mandatory". Maybe the IESG can better explain that?
Michael

Hi, Mirja,
One clarification, for the record, inline.

Hi all,
find below an IPR disclosure that was filed last week related to
draft-ietf-alto-deployments. This is a third-party disclosure for a patent
application that lists this draft as ‚document to be considered related‘. See:
https://data.epo.org/publication-server/rest/v1.0/publication-dates/20
150902/patents/EP2913979NWA1/document.pdf
The IETF last call for draft-ietf-alto-deployments was performed between June
7 and June 21, 2016, while the IPR disclosure was submitted afterwards (as
reaction to the OPS-DIR review).
I was actually the OPS-Dir Reviewer assigned to draft-ietf-alto-deployments-15.
I submitted my OPS-Dir review delayed, after the IETF LC ended, because I was
on vacation (and unreachable) when I received the OPS-Dir review assignment. As
part of my review, as I came across those two (not only the one you include
above) published patent applications potentially relating to the subject matter
as indicated in non-patent citations, I had to submit that 3rd party disclosure.
Thanks,
— Carlos.
If this disclosure raises any concerns regarding the publication of this
draft as RFC, please state your opinion on the alto(_at_)ietf(_dot_)org
mailing.
Thanks,
Mirja - responsible AD
