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 agree that it is good to use Vorbis, Theora and WebM, but that still doesn't help if the video you want to see is encoded in MPEG-2 or the audio you want to hear is encoded in MP3. Unlike the GIF format, both encoding and decoding of MP3, MPEG-2 and H.264 are patented.
