I know next to nothing about laws pertaining to copyright/trademark infringement. To what extent do they apply to iPhone apps? Am I allowed to create a game which is identical to a commercially released board game as long as I call it something else? An example is the "4 in a Row" game. The developer of this game did a very nice job even down to the etchings on the playing pieces. As a developer, do you have to get the permission of someone like Milton Bradley?
