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.

Well first of all claiming Theora is in anyway close the H.264? Sorry but you're dreaming. You'll need twice the filesize to get comparable picture quality. And frankly Ogg is a very badly designed container* with numerous problems.

Second if you think any of those are free of getting hit by the patent hammer? think again. Have you SEEN the MPEG-LA patents? we are talking about over 200 patents covering just about every stage of compression and decompression. They haven't been hit by the hammer yet simply because they are a teeny tiny niche not worth chasing by MPEG-LA. If you were able to actually get the public (who frankly doesn't care about this mess because their devices "just work" and that is all they care about) to use these codecs? they would spend the next decade in court.

That is why thinking you can geek around this stuff is simply a fallacy. the ONLY way to deal with this stuff is in the courts not in the lab. Sadly I doubt anyone in the know has enough money for the massive bribes it will take to get congress to do anything about it so things will only get worse. Of course the net result will be a major WIN for China and India who won't play our little reindeer games and thus will still get to innovate while the corps in the USA go "where's my check?". All the rest of us can do is wait for the patent clock to run out, or in the case of copyrights hope our great great great grand-kids live long enough to see something actually enter the public domain again.
