As used herein, Qualified Parties means a party who has not, does not and 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 SDK because that licensee implements or practices the ZRTP Specification.

PRZ will grant non-exclusive licenses to Non-Qualified Parties on reasonable and reciprocal terms and conditions. For further information, see http://philzimmermann.com/zfone
