Since Puzo probably didn't die poor, I'd rather he (and others in his position) leave the money he already made to his estate and let the IP open up for others to try their hand with it.
If you want to make money from your IP, you do it through licensing. If thats the model you follow, then suing the pants off of those who don't pay up is kind of what you have to do. Otherwise you don't get money.
If you don't want to make money, or don't care about it, there's still good reason to lock down your IP. You want only positive usage of your IP, so you set rules to how it can be used and by whom. Anybody who doesn't follow the rules, you sue, for the good of the IP.
In this case, there was an agreement between businesses. IP was used, a game was created, and one of the parties says they never received their due. Asking your business partner to fulfill the agreement in now way stifles creativity. If anything, it encouraged it, since by allowing the game to be made, good or bad, somebody took a crack at making something with the IP. I see nothing wrong with what the Puzo estate is doing. They have very few alternatives that make any sort of sound business sense.This comment was edited on Jun 19, 13:26.
