Theoretical circles believe that fictitious marks, arbitrary marks and implied marks have inherent distinctiveness and can be directly registered as trademarks. Descriptive symbols can only be registered after they have obtained the second meaning through use, that is, the salience; Generic names are strictly not allowed to be registered. The theoretical basis of this division and regulation lies in the influence of trademark registration on market competition. William M. William M. Landers believes that "the protection of trademarks that can't distinguish the brand of a product from another brand, or trademarks composed of words, symbols, shapes or colors used by other producers of the product, may hinder the effective competition of others". Because whether a trademark has an adverse impact on market competition mainly depends on the supply of such trademarks, for a specific product, the more similar trademarks or replaceable trademarks, the less impact the trademark has on competitors, and vice versa. Theoretically, the number of fictitious trademarks of a product can be endless, and the adverse effects on the commercial use and expression of competitors can be almost ignored. Similarly, there are many words that can be used as arbitrary trademarks, which have little adverse impact on the commercial use and expression of other competitors. And "the supply elasticity of implied trademarks is smaller than that of fictional trademarks and arbitrary trademarks, but if we consider the substitutability between trademark types, it is actually not much smaller than the latter."
