Cisco's Statement about IPR claimed in draft-mcgrew-srtp-ekt-00.txt
Date: 6 April 2006 
From: Dan Lang <dlang@cisco.com>

Cisco is the owner of one or more pending unpublished patent applications> 
relating to the subject matter of "Encrypted Key Transport for Secure RTP" 
<draft-mcgrew-srtp-ekt-00.txt>.

If technology in this document is included in a standard adopted by IETF 
and any claims of any Cisco patents are necessary for practicing the 
standard, any party will have the right to use any such patent claims 
under reasonable, non-discriminatory terms, with reciprocity, to implement 
and fully comply with the standard.

The reasonable non-discriminatory terms are:

If this standard is adopted, Cisco will not assert any patents owned or 
controlled by Cisco against any party for making, using, selling, importing 
or offering for sale a product that implements the standard, provided, 
however that Cisco retains the right to assert its patents (including 
the right to claim past royalties) against any party that asserts a patent 
it owns or controls (either directly or indirectly) against Cisco or any 
of Cisco's affiliates or successors in title; and Cisco retains the right 
to assert its patents against any product or portion thereof that is not 
necessary for compliance with the standard.

Royalty-bearing licenses will be available to anyone who prefers that option.
