Oh, the tangled web
When Patent Guilds
Conspire as thieves.
Patents today have become like some magic amulet from D&D. You only have to possess it for a short time to impart its magical protection to you forever. After that, you're free to pass (sell) it on to the next troll who needs to up his powers.
Does anyone really believe that MS will not, as a term of the sell, keep an eternal license to the patents just as AOL likely did in its sell to MS?
Patents must DIE.
