Each patent pool generally offers a license to a different set of essential patents. So to the extent a company determines it needs a license to both of those separate sets of patents then yes, they would need to join both patent pools. I would note that HEVC Advance has offered the opportunity for all of the MPEG LA licensors to join the HEVC Advance patent pool with no change in our royalty rate structure. If that was to happen then companies would only need to join the HEVC Advance patent pool to obtain a license to both sets of patents.
Concerning Technicolor, please note that Technicolor did not exit both pools, rather Technicolor did not join either pool. That is, they were never a licensor in either pool. I believe the ramifications of Technicolor not being a licensor in either pool is negligible. It is my understanding that Technicolor has a relatively modest portfolio of essential patents, so IF they sought licenses from companies in this market category and IF companies determined they needed a license to those patents, then I would expect the royalty rate would also be modest. In any event, the licensing group at Technicolor is a professional organization and I have no doubt that they will act responsibly and not hinder adoption of HEVC technology. And who knows, maybe they will reconsider and decide to join either HEVC Advance or MPEG LA in the future.
