I believe that for all parties to feel that all intellectual-property issues
are being addressed in the most explicit fashion possible, all of this
group's drafts should include the following text. I apologize for the
"Cisco Systems has an issued patent (US 6,052,718) and patents pending that
may relate to this proposal. If this proposal is adopted by the IETF and any
patents issued to Cisco or its subsidiaries with claims that are necessary
practicing this proposal, any party will be able to obtain the right to
implement, use and distribute the technology or works when implementing,
using or distributing technology based upon the specific specification(s)
under openly specified, reasonable, non-discriminatory terms."
I will further note that to the best of my personal knowledge none of the
pending patents relate specifically to CDI or "content peering." However,
they do relate to aspects of "content distribution technology" and so it's
hard to argue a priori that CDI would be completely unaffected by them.
Again, my apologies for the timing. I should have sent a version of this
message a week or more ago but lost track of it as a to-do, and only
realized today that it was still undone.
