This all assumes the USPTO (US Patent Office) actually reviews applications for prior artwork and all that. They don't. There are MANY patents that overlap and have the same elements are others. The entire process is a mess. And then it's all about litigation. To say this makes for better competition in the marketplace is complete hogwash. It has nothing to do with that. Patents only protect large corporations with the resources to legally protect their patents. It's all about profit.
