They can patent a process that gives them very reliable dosages, though. And like the other reply said, the Generic companies aren't relying on the patent protection anyway. They might find different sorts of chemical structures that are theraputically superior than LSD itself as well, but this stuff wont' happen without minimally having LSD medically legal. They can still sell the patented "alternatives" : LSD isn't a cure-all and isn't necessarily ideal for everyone. Besides, these patents will eventually run out, so they'll have to think up new ideas nevertheless.
