Not only Kodak... color management is fullfilled of patents.

Here are some:

http://www.frontiernet.net/~shyam/colormanagement.htm

Please note that these are USA patents, and does not apply worldwide.

I have tried to do my best to avoid any patent, and implement
only what the ICC spec provides. There was only one part, tetrahedral
interpolation, that was  under patent  when I wrote the core engine.
For this reason the default interpolation is trilinear and there is a toggle to
select tetrahedral at compile time. Anyway, Sakamoto's patent, is now expired.

I cannot assure the code is completly completly patent-free, but I have taken
this issue seriously. If you or anybody does know some portion of code
breaking any patent, please let me know. I will remove that part or provide
a workaround as fast as possible.
