There is no trademark printed on the lid of the Red Rhododendron Casserole, so it is not fake. A product does not necessarily have a registered trademark, because the country currently registers trademarks. Except for cigarettes, which require compulsory registration, other products or services are voluntarily registered. Therefore, if the product you purchase does not have a registered trademark, it does not mean that it is a fake. To determine whether a product is counterfeit or infringing, registered trademark is only one of the factors. The judgment must also be based on price, physical appearance, performance, quality, and manufacturer identification.
