Title: Rene Struik's Statement of IPR Related to RFC 6189 belonging to Certicom Corp. Submitter: Rene Struik Date: 2011-08-03 Dear colleagues: Hereby, I would like to notify IETF of potential 3rd party IPR that may be relevant to RFC 6189 - ZRTP - Media Path Key Agreement for Unicast Secure RTP (April 2011). This disclosure is based on best effort and does not judge on validity of patent claims (I am no lawyer, after all). I do not like to be put in the position to make third party declarations, but felt the duty to notify to the IETF community, even at this late stage. Best regards, Rene == 1.

Additional notes Given the timeline of the current draft (it has been an RFC for months now (since April 2011), after having passed LC stage a year earlier) and since I have not seen any disclosure of potential IPR posted on the IETF website to-date, I felt the duty to notify. This disclosure is based on best effort and does not judge on validity of patent claims (I am no lawyer, after all).
