But you have a lot of legwork to do. If it was as easy as "Hey! I have an idea! I'm going to make 1% in perpetuity!" everyone would do it.
You have to have reduced that idea to practice, meaning, it has to be tangible. If you just say "Hmmm, it would be really cool to have pencil erasers that taste like cherry!" or "Wouldn't it be neat to have a little portable handle for your weiner when you go to the men's room so you don't spread germs?", that's not enough to be patentable.
Remember also, patents are simply the right to stop others from using your innovation, not the other way around. Many patents have little licensing value because they build on other patents that prevent them from being used. Think of the pencil and the eraser. Just because you thought of the eraser, doesn't mean it's worth anything unless you also have the right to make the pencil itself.
If you're serious, you may want to contact an attorney; I would stay away from those clearinghouses that advertise for your ideas; they WILL take some or all of the proceeds from the patent.
