A friend said to Lao Yang, who said to Putui trademark, that a trademark has been registered in the trademark category, but some subclasses have not applied for registration, so the registered trademark can be used in this subclass.
Take the 30 classes of convenience food as an example, for example, the product that has been registered in the "flour" subcategory, the trademark of the same name is not possible for others to apply for the trademark of all products in the subclass of 3008 is highly likely to be rejected, it is a similar commodity, the holder wants to play r on the "corn coarse meal" is not recommended, others are unable to apply for registration, it is recommended that you can use it without playing r, if the product of the "cereal products" subclass has been registered, you can basically play r on the "corn coarse meal".
Yes, it can be used, but some can play R, some can't play R, the name chosen is a large generic name, including more products, so that it can be used more widely, and at the same time it can also be exclusive. Some companies will also apply for the registration of multiple trademarks or more than 10 products or services in one category, so as to include enough products or services.
