Do I need a license from someone else besides Polycom?
To our best knowledge and belief, no. Our belief is that all patents on Siren 14 technology are owned by Polycom. The algorithm is identical to that of ITU-T G.722.1 (Siren 7 audio technology), which has been in the market since 1998, and as of this writing (April 2005) no other party has claimed otherwise, even informally. However, as with any technology, it is always possible that third parties may claim, correctly or not, to have rights that are infringed by Siren 14 technology. Ultimately only a court of law can decide the validity of such claims. Polycom offers no guarantees that no one will make such a claim in the future, and will not compensate licensees for losses resulting from any such claims. Licensees are responsible for their own risks in this regard.
