> buy patents Whose non-existant patent would they buy under the new system where the non-practitioner can't have one to sell? Or I can see you could only let practitioners enforce, but what would be the details on that? The non-practioner could just threaten to become a practitioner or sell to one in exchange for a settlement from someone violating, or if prior violators were grandfathered in once practitioning from the holder began, it would be a race to violate as many as possible before they could be put into practice, in order to get them free through grandfathering.
