No need to apply for a patent. Instead, it is a registered trademark.

For example, McDonald's has registered a large number of trademarks for its services and products. For example, McDonald's is its service trademark, and it has registered separate trademarks for various products, such as Big Mac.

When he obtains the exclusive rights to these trademarks, other companies cannot use the same brands and logos. But others can still make products, such as burgers, everyone can make them.

Regarding patents, McDonald’s has also applied for a large number of patents, such as baking components, patent number 03808465.1; automatic grill, patent number 03808737.5; device and method for grilling food on the grill, patent number 200680043544 .X, etc., you may understand after reading this. He applied for a patent for the device and cooking method he used. Common foods cannot obtain patent authorization because they are not novel.

For newly invented foods, it is possible to apply for a patent. For example, the patent number is 95197315.0, the name is "food", and the content of the invention is: a new type of food contains a fat content of at least 3, preferably at least 5 and dairy products with a gelatin content of at least 0.1.
