IV. Disclosure of Patent Information
i.e., patents or patent applications required to be disclosed by RFC 3979

A. For granted patents or published pending patent applications, please provide the following information:

Patent, Serial, Publication, Registration, or Application/File number(s)

Not known
Date: Not known
Country: Probably US

Notes: Several years ago I heard that Hewlett Packard had a patent on cross-net latency
measurements that used GPS time sources. (Given that HP split itself in two,
the patent, if it exists might be owned by Agilent.)

I have no idea whether I was hearing (or mis-hearing), much less any details on
the patent.

This RFC might suggest something that, if implemented, might impinge on that
patent (assuming that it exists.)

I hate to be so vague, but I don't have anything more concrete. I was working
on some net measurement tools myself (e.g. ) and remember that I and
several others avoided using GPS time measurements for transit-time measurements
precisely because of the existence of this putative patent.

By-the-way, as for question "B" below, I have no idea whether what I heard
about was an unpublished application. But it was several years ago so any
period of non-publication ought to have expired by now.

B. Does this disclosure relate to an unpublished pending patent application?:

Has patent pending No
