I think you are correct: ANS is an entropy coding method, so a patent shouldn't be able to claim a new use for encoding some specific type of information [1]. Also, Duda's paper even exemplifies the obvious use case for video compression [2].

Unfortunately, that's not the case, at least as the patent office currently sees things. There's thousands of patents for H.264 and HEVC that amount to "code a certain bitstream symbol with CABAC this certain way".

If that's the case, that's a terrible perversion of the intended purpose of patents. The progress of science and the useful arts would probably be better served by putting the entire patent system on hiatus for a few decades.
