"Seduction is often difficult to distinguish from rape. In seduction, the rapist often bothers to buy a bottle of wine."

If you didn't have patents, no one would bother to spend money on research and development. But with patents, if someone has a good idea and a competitor can't copy it, then that competitor will have to think of their own way of doing it. So then, instead of just one innovator, you have two or three people trying to do something in a new way.
