This sums up the situation

IANAL, and I know basically nothing about codec patents, but it might be worth noting that there are a whole bunch of video coding techniques that are presumably completely unnecessary for decoding video *stills*, i.e. I-frames.  Things like motion compensation are irrelevant if there's no motion.

So it's at least slightly plausible that any patents in question wouldn't apply to a heavily stripped down decoder that only implemented the parts of the spec needed to decode HEIF.
