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.

I am not really that concerned since we have Vorbis, Speex, Theora, VP8 and others which come very close and in many cases surpass the patented offerings. These are examples of the very best in engineering efforts, as evading patented technologies and still making a superior product is so complicated.

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?
