 It's always a question of degree, isn't it? Because intellectual property does not stop a person from being inspired by someone else's idea. It stops people from slavish imitation, as we say. And there must be some degree of similarity permitted, or else you couldn't have a fashion. It would not be possible to say that this is the fashion is whatever it might be. Gothic, let's say. There are certain common elements to constitute a fashion. But, and that is permitted. However, you cannot slavishly imitate or copy. Just as you might say that there are certain common elements to a school of art. So impressionism has something in common. But you can't, you know, you couldn't at the time just take one of Monet's paintings and reproduce it exactly.
