What Is a Class?
In a trademark application, a class is, simply put, a category of goods or services.
There are 45 classes in total. Classes 1 through 34 cover goods, while Classes 35 through 45 cover services.
For example, pharmaceuticals, advertising and consulting services, restaurant services, and legal services are assigned to specific classes under the classification system used by the Japan Patent Office (JPO).
The appropriate class or classes depend on the goods and services for which you intend to use and protect your trademark.
