“Rowling’s ability to stop the Potter pretenders is largely a function of the new regime of international copyright.

And the borrowing of characters itself has a longer tradition.” Tim Wu —Harry Potter and the International Order of Copyright: Should Tanya Grotter and the Magic Double Bass be banned? (Slate)
