By that I mean people who live to get their ideas out. People who have various ideas and want to see them done, maybe not by them, but they want to receive the full credit and full benefits (money?) for them. They don't want fame, they don't want people to recognize them when they walk down the street, they simply want the credit and the benefits, as they see it as a fair thing to do - after all, the idea was theirs, and selling ideas isn't a thing that they would want to do.
Here's an example: Joe thinks of how to make computer coolers more efficient, and assuming he's got the right tools - he reworks his computer coolers at home. However, he doesn't tell any of his friends about it, nor reveals it at all. He may merely mention that he's made his coolers much more efficient, but nothing more. Eventually, someone told someone, etc., and a guy comes knocking at his door. The guy wants to know how he made the coolers more efficient and if proven, he offers to buy his idea off of him, however he wouldn't receive any credit and would get a one-time huge payment. He refuses the deal because he wouldn't get the credit and he wouldn't get the further benefits (even though the one-time payment covers 10 years of what he'd make from selling those coolers). He also isn't going to make and sell them himself, or patent the idea, as he doesn't have the money to do so. He "hopes" that he will, eventually, be able to patent the idea, start a company and sell the coolers himself. Not to be recognized, known, etc., but because it's his idea and he wants to play with it and control the implementation of it himself.
Which types would those be? Here's what I know, whether it's correct or not: ENTJs want only to make an idea come true, make it practical, maybe even cut some cool feature out because it would cost too much without doing any research about alternatives. ENTPs simply have lots of ideas, and rarely they go as far as implementing them. INTPs seek to deconstruct things, and if they have the idea, they would like to be behind the scenes, maybe getting the credit, maybe not. INTJs don't get many ideas, they can work on one idea all their life, especially if it's something that pays good.
