Also, the licensing terms are fixed at a maximum 10% rise per five-year renewal. Given the lifespan of patents, that's a low ceiling.
This is the first I've heard of this. Since one of the main concerns I've heard is that MPEG-LA could raise fees to unacceptable levels, do you mind providing a source for this? I'm still less comfortable with H264 being the standard rather than WebM, but this makes me less worried. (Anti-FUD?)
