Thank you and congratulations, DWA!

I wanted to congratulate and send a big thank you to DreamWorks 
Animation for the new DWAA/B compression algorithms.  They are fantastic.
I have one question about the patent, however.  I would like in the 
future to integrate the compression algorithm with ffmpeg. ffmpeg being 
a C program only does not include any C++ code. Currently its OpenEXR 
support has been manually recoded in C (it does not use OpenEXR's 
limited C API).  Coding the DWAA algorithm in ffmpeg would probably 
infringe on the patent.  So that's my question.  Would it be possible to 
extend the patent to cover a possible future ffmpeg (re)implementation?
