In the decision of the Supreme Court (SC) issued on February 2 2007 in McDonald's Corporation v Macjoy Fastfood Corporation, the SC employed the dominancy test to affirm the decision of the Intellectual Property Office (IPOPhil) that the predominant features of the McDonald's marks (namely its corporate logo known as the golden arches or M design, McDonald's, McChicken, MacFries, BigMac, McDo, McSpaghetti, McSnack, and Mc), are the "M" logo design, and the prefixes "Mc" and "Mac", and found confusing similarity between the McDonald's marks and the opposed Macjoy and device mark, especially since both are used on the same products falling under Classes 29 and 30.
