Here it is.  For more info refer to PATENTS in the openexr distro:

Additional IP Rights Grant (Patents) "DreamWorks Lossy Compression" 
means the
copyrightable works distributed by DreamWorks Animation as part of the 
OpenEXR
Project. Within the OpenEXR project, DreamWorks Animation 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,
import, sell products which incorporate this IP as part of the OpenEXR
standard, transfer, and otherwise run, modify and propagate the contents of
this implementation of DreamWorks Lossy Compression within the OpenEXR 
standard,
where such license applies only to those patent claims, both currently 
owned by
DreamWorks Animation and acquired in the future, licensable by DreamWorks
Animation that are necessarily infringed by this implementation of 
DreamWorks
Lossy Compression. This grant does not include use of DreamWorks Lossy
Compression outside of the OpenEXR standard. This grant does not include 
claims
that would be infringed only as a consequence of further modification of 
this
implementation. If you or your agent or exclusive licensee institute or 
order
or agree to the institution of patent litigation against any entity 
(including
a cross-claim or counterclaim in a lawsuit) alleging that this 
implementation
of DreamWorks Lossy Compression or any code incorporated within this
implementation of DreamWorks Lossy Compression constitutes direct or
contributory patent infringement, or inducement of patent infringement, 
then
any patent rights granted to you under this License for this implementation
of DreamWorks Lossy Compression shall terminate as of the date such 
litigation
is filed.
