Regardless, it would be darn rude to do it without permission of the inventor. They made a great product. If they do not make it or cannot make it anymore, perhaps they would be happy to let it go to someone else or accept a small percentage of the profits. But the right thing to do is to talk to them about it first.
Say what?
I don't think that's how it works.
(In my understanding), absent patent protection, the market expects competitors to enter the market. You can't duplicate copyright items, so no copying the artwork, but otherwise, if a company can create a competitive product, that's all to the best.
