No, they don't have to show anything "dramatic" at all. A patent only has
to show uniqueness and workability.

Making mony is irrelevant to a patent, though since one has to pay money
to get a patent, it's a good idea.

History? Publication will prevent (in an honest world) someone else from
patenting your idea. You'll still need a lawyer and a pile of money if
someone else does patent your idea.
