The MPEGLA site has this caveat " Up to and through date of last patent expiration" and I'm wondering if anyone knows that date? I couldn't find the definitive list of patents in the license product on any of the 'open' pages. On each pool, there's a prominent link for the patent list applicable to the pool. For example, the patent list for the AVC pool is here: http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx http://www.mpegla.com/main/programs/AVC/Pages/PatentList.asp... It's not secret, or 'closed'.
