Patents without assuming that independent discovery was a copy are pointless. We have copyright for that.
How do you figure? The point of patents is to protect inventions, which is something copyright can't do, because it protects only expressions. How do you suppose copyright would stop Merck from manufacturing and selling a drug that Pfizer invented? Assume that Pfizer could prove Merck learned how from Pfizer's paper on the subject, so that independent discovery is not an issue.
