Haha, no. What happens when a normal person like you or I slave away at something that no one else would have been able to do only for a huge company to say " o hey that cool, lets copy it and slap our sticker on it!"?
Well then you probably should have been working for such a company in the first place if all you can do is invent and you don't have the ability to market, sell, and distribute the product as well. Just because you invent something doesn't mean you're all of a sudden entitled to a mountain of cash.
