Internet & Networking Despite the recent interest in adopting HTML5's video tag, there is still one major problem: there is no mandated standard video codec for the video tag. The two main contestants are the proprietary and patended h264, and the open and free Theora. In a comment on an LWN.net article about this problematic situation, LWN reader Trelane posted an email exchange he had with MPEG-LA, which should further cement Theora as the obvious choice.

Thom, maybe you haven't noticed, but usually the patent trolls emerge when a technology is already in wide use and popular.

In order for there to be a patent troll against Theora, there has to be a patent that was awarded before the patents for VP3 were awarded to On2. In addition, the USPTO has to have made a mistake, and awarded that earlier patent, and also On2's patent(s) for VP3, so that they covered the same methods for video compression.

That is highly unlikely.

If a patent troll turns up with a patent that was awarded after the patent(s) for VP3 ... big deal. The patent(s) for VP3, being earlier, trump any later ones covering the same video compression methods.

That would only apply if On2's patents covered each and every part of the codec. It is far more likely that On2's patents cover somer major parts of the codec but each and every algorithm etc used in it.

The fact that On2 has some patents absolutely does not guarantee that there couldn't be any older patents covering some parts of the codec.
