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?

This is a third-party disclosure for a patent application that lists this draft as ‚document to be considered related‘.

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.
