Has Nintendo shut down a game because it cloned the gameplay of one of their games?

Welcome to the game development community! This is a place to talk about and post anything related to the field of game development.
Even in their case, the phrasing within their patent form is fairly specific to their games. Unless one completely clones the system, I would be surprised if they got legal trouble for it. Better to check with a qualified lawyer of course.
