Note that there's some patents that haven't yet expired, at least in the US. AFAIK this is because if there's delays in patent examination you get extra duration on your patent to compensate. Here's a list of the patents that were filed before High Profile was standardized and are still valid: https://meta.wikimedia.org/wiki/Have_the_patents_for_H.264_M...

Of course MPEG-LA deliberately makes figuring out which patents cover which parts of H.264 (which is really a set of multiple standards spanning a 10+ year period) ambiguous and hard to determine in order to sell more licenses.

I can't afford to claim otherwise.
