> what's left after getting rid of the bad patents is "very limited".
Nonsense.
MPEG LA claims that H.264 is covered by about 50 patents in any given country.
Invalidating 45 out of 50 would change *nothing* (even with just one patent, you can't develop or distribute). And current invalidation efforts have invalidated zero out of 50.
The "bad patents" topic is a distraction used by pro-swpat companies and their sock puppets.
