Re: Comments on zrtp-03: non-technical
I thought the main issue was the part regarding the disclosure flag.
If it's simply the question of making a free license depend on people
not suing me for patent infringement, I got that wording from a
number of other people who said that it was a common element of many
IPR disclosure statements submitted to the IETF. I think it's a fair
trade to require reciprocity in patent usage. I'm using it
defensively, which many regard as a reasonable and generous way to
use a software patent.

One part of the comment that I (IANAL) find confusing is this:
"As used herein, Qualified Parties means a party who has not, does
will not assert, in litigation or otherwise, including in licensing
discussions, any patent or other intellectual property right
against PRZ of
any nature, or assert the same against any licensee of the libZRTP
connection with such licensee's implementation or practice of any IETF
standard incorporating the ZRTP Technology."
Perhaps lawyers read it differently, but "any patent or other
property right against PRZ of any nature" doesn't seem to be
issues revolving around ZRTP and the IETF spec (as is explicitly
licensees). So, to give a random example: IBM agrees to use ZRTP.
cannot now in any way use *any* patent against PRZ. PRZ is
(say) Samsung. Now IBM can't use *any* patent against Samsung
losing it's license to use ZRTP).
Was this intentional? Do I read this right?
