Full-class trademark protection means that the applicant specifies all categories of goods and services when applying for trademark registration, so that its trademark is protected in all categories. Some people think that it is not necessary to apply for full class registration when the trademark is not yet well-known. However, it is better to defend beforehand than to relieve afterward. Trademark is an intangible asset, and intangible assets can be converted into tangible assets, creating endless economic benefits for enterprises. If the company develops and its trademarks gain popularity, these registered trademarks can be licensed or transferred for a fee, and franchised, so that the company's strength will continue to expand and it will develop in the direction of diversification and groupization. Therefore, registering for all categories is not just about spending money to buy peace of mind. Full-class registration can be said to be a protective investment behavior that can lay the foundation for the diversified and group development of enterprises. In addition, registered trademarks can be pledged after evaluation by relevant departments to provide guarantees to creditors.

According to Article 51 of my country’s Trademark Law: “The exclusive right of a registered trademark is limited to the approved registered trademark and the approved goods for use.” This shows that the protection of registered trademarks is limited. This provision of the Trademark Law also defines the scope of protection of registered trademarks. Generally, registered trademarks are only protected by law within the category in which they belong. The so-called all-category protection means that all categories are protected.

To be protected in all categories, there are two ways: one is to become a nationally well-known trademark and enjoy all-category protection prescribed by law; the other is to register it in all categories. "Full-class registration" refers to the behavior of the same applicant applying for trademark registration to the Trademark Office of the State Administration for Industry and Commerce for the same trademark in all categories listed in the "Classification Schedule" (currently there are 45 categories). For small and medium-sized enterprises, it is not easy to own a nationally well-known trademark. To fully protect themselves, registering a full range of trademarks is a good way. The total cost is about 80,000 yuan, which is generally more common in large companies.

Some people think that it is not necessary to apply for full class registration when the trademark is not yet well-known. However, it is better to defend beforehand than to relieve afterward. As a resource, trademarks are always becoming less and less. By the time a company's trademark becomes somewhat famous, many people may have legally registered trademarks identical or similar to it in other categories. By then, the trademark will be created. People will be in a passive position. If the trademark founder takes the lead in registering all categories, it can prevent others from legally acquiring exclusive rights in other categories as the trademark grows.

Secondly, trademark is an intangible asset, and intangible assets can be converted into tangible assets, creating endless economic benefits for enterprises. If the company develops and its trademarks gain popularity, these registered trademarks can be licensed or transferred for a fee, and franchised, so that the company's strength will continue to expand and it will develop in the direction of diversification and groupization. Therefore, registering for all categories is not just about spending money to buy peace of mind. Full-class registration can be said to be a protective investment behavior that can lay the foundation for the diversified and group development of enterprises. In addition, registered trademarks can be pledged after evaluation by relevant departments to provide guarantees to creditors.
