I could be completely wrong here, but it seems to me that everyone with some idea thinks that companies are just waiting for a great idea to appear so they can steal it when in fact companies can’t even move forward with stuff they want to do, let alone stuff that nobody has ever seen. Adding to that, even truly great products don’t sell themselves nowadays and that’s the reason people and companies spend millions of dollars in advertising and marketing. You can invent a time machine but unless you can spread the word out there nobody is going to buy it or care. I guess what I’m trying to say is: work on your product and pray that someone picks it up. If it’s complex and super hard to reproduce chances are that people will try to get you on their side as opposed to stealing it from you. If it’s simple then you should not worry about it because companies will copy it anyway and even if you have a patent it’s useless if you can’t defend it, in the US or overseas. Focus on your product and trying to sell it.
