They can't take that away. Sure it's reasonable to regulate the selling of the patented or copyrighted product, but to regulate how you use it is just wrong.

No law out there that I know of, makes it illegal to use a patented/copyrighted item you bought for your own use however you want to. It only covers what you do with that work when you give/sell it to someone else. If you make your own segway, they can't sue you.
