Only when a trademark is attached to the product package or product and used together with the product name can consumers distinguish the source of the product. The product name is used to distinguish the different raw materials and different uses of the product. Use independently. Trademarks are specific and exclusive, while trade names (except for unique names) are usually public. Product name is one of the important parts of the entire trademark registration work, and it determines the scope of registered trademark protection. Therefore, when applying for trademark registration, the specific names of goods and services must be specified. Moreover, the goods or services reported on an application can only be limited to one category. That is, the product name and trademark name do not need to be consistent.
