The Olympic Charter defines the five-ring symbol and claims it as the exclusive property of the International Olympic Committee. It not only asserts a right to international trademark protection but requires all member nations, through their national Olympic committees, to assert and protect the exclusive use of the symbol, as well. This is why, at the time of the games in Atlanta, the organizing committee was successful in compelling a local fast-food drive-in restaurant to stop using, in its advertising, a picture of five onion rings, so arranged as to mimic the official Olympic symbol.
