Can I paten a technique for saving people's lives that requires no tools and anyone can learn, but no human being has ever done it before (intentionally)?
The paten question is no triviality and should not be treated as such. Don't think "oh why don't they just revoke it". Perhaps what is wrong with our system is the time given, 7 years in software terms may as well be a lifetime, while 7 years in physical product terms is hardly anything. Thats the problem with our system. And copyright is a whole nothing monster. They mingle often, but are not the same.
