Legal Patent term calculation is complicated in the US because there are essentially two different systems and quite a few corner cases. Even with a list of patents, it can be tricky to determine when the patents are all expired. Since I am a computer programmer (and not a lawyer), I created a program to try and automate this. This paper discusses how patent term calculation works, and some results from a combination of hand and automatic term calculation for MP3, MPEG-2 and H.264.

As for MPEG-2, how come a technology that has been standardised by ISO is patented? Maybe some parts of it have been omitted from the standard? Like particular algorithms, modes or encoding profiles. But why standardise an incomplete/limited/broken technology in the first place then?
"standards" (even more so ISO standards like MPEG) are not "knowledge", that must (or should, at least ideally) be accessible to anyone for free (thus, public domain)...
their point is merely interoperability between *industrial* products (say, between a factory made dvd player and a factory stamped dvd-video, or a professional tool that will be used to author the dvd itself)
it's NOT to let *anyone* design and make his own thing possibily disregarding relevant parties that have a right to get their work compensated

and (most important, their intended) target is not the general public , it's members of the industry who can afford to pay for other parties' IP contained in their products (which becomes simply another item in the BOM)

OTOH nothing forbids one being a design-only firm, choose to work on algorithms alone, and yet retain the right to propose their own work as (/part of) industrial standards (it's others' choice to approve or follow them as such or not) and receive compensation for it..

welcome to the industry as it works..
