I understand that logic and have heard it before. However, it has a fundamental problem. Patents do not protect abstract ideas; they protect concrete inventions. I cannot patent "a means of traveling backwards in time" because that is an idea. As far as we know it's also impossible. You can't get a patent on "A surface that has zero friction" unless you also create that surface and explain how to do so. The idea that any physicist who is "skilled in the art" could figure out how to create such a surface from the laws of physics (which it surely must follow) is silly. On the other hand, software patents are exactly like that. I can patent "A method whereby clicking a button solves P=NP" and simply claim that the solution is produced somehow. I have to give no example implementation or even very specific details. This is highly at odds with other industries. I do understand the legality of it, but it's still significantly different than other fields and leads to inane results.
