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.
If there were older valid patents, prior to circa 1997, belonging to someone else other than On2, which both On2 and the USPTO missed entirely, and which are still valid to this very day, covering some aspect of video compression technology as used in VP3, for which in all this time the owner has never made any demands at all, I would be utterly astounded.
Considering that VP3 patents were seen as obsolete, and handed over to open source in late 2001, that would be the timeframe. Perhaps earlier.
Highly unlikely. Extremely unlikely.
