I'm not sure there's really a bill in place to take away our rights and there's another thread under Open Discussion about the same thing.
Right now, when you create something by writing or graphics or even music, you are automatically given rights to your work. If someone steals your work, you don't need to have registered the work to have a case. Some people's work slides, after they have already died or for whatever reason that they have let their copyright slide for 50 years. These are orphaned works. No one seems to own them. Hence, orphans. It's probably in the same vein, if someone creates something and doesn't attach their name to the work. Since no one knows who owns the work, it is designated as an orphan.
