There's no mention of a patent grant. Does anybody know the state of ALAC with regards to patents?



I believe the apache 2.0 license [1] includes a grant.

     3. Grant of Patent License. Subject to the terms and 
     conditions of this License, each Contributor hereby grants 
     to You a perpetual, worldwide, non-exclusive, no-charge, 
     royalty-free, irrevocable (except as stated in this section) 
     patent license to make, have made, use, offer to sell, sell, 
     import, and otherwise transfer the Work, where such license 
     applies only to those patent claims licensable by such 
     Contributor that are necessarily infringed by their 
     Contribution(s) alone or by combination of their 
     Contribution(s) with the Work to which such Contribution(s) 
     was submitted. If You institute patent litigation against 
     any entity (including a cross-claim or counterclaim in a 
     lawsuit) alleging that the Work or a Contribution  
     incorporated within the Work constitutes direct or 
     contributory patent infringement, then any patent licenses 
     granted to You under this License for that Work shall 
     terminate as of the date such litigation is filed.

So, the next question is: is the container format (MPEG-4 Part 14) patent encumbered?


There is no active patent pool for MPEG-4 systems.
