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.

What makes you think that these formats are not covered by patents? Are you aware that the patent claims on JPEG only surfaced after the format had been in use for over fifteen years?
