I always assumed there would be patents on the software processes for
encoding and decoding. It seems to me that you could patent novel
parts of an encoder, even if the format is 20 years old. Then you
could sue anyone who tried to build an encoder using similar techniques.
I would have trouble believing that all of the companies involved are
too benevolent to try this.
