First, it is a kind of protection for one's own rights and interests.
Take Li Jiaqi Voice's trademark application for example. Because his delivery style in Li Jiaqi is imitated by many bloggers and can be recognized by many consumers, many people will imitate Li Jiaqi's sales style and even deliberately imitate Li Jiaqi's voice to help them sell their products in order to increase the sales of their products. Therefore, this will have some influence on Li Jiaqi himself, that is, others will buy some goods because of his voice, but if he is a seller himself, it has nothing to do with Li Jiaqi. However, Li Jiaqi's popularity is used for sales. If he seriously cheated consumers, consumers may be angry with Li Jiaqi, which will harm Li Jiaqi's rights and interests.
Second, avoid opportunistic people from having a negative impact on themselves.
Because we know that many people will use Li Jiaqi's sales methods to sell their products online. However, not all merchants are customers who only sell excellent quality goods. If a fake and shoddy business imitates the style of Li Jiaqi, many consumers buy these fake and shoddy goods by virtue of their good feelings for Li Jiaqi, which eventually leads to some adverse effects on consumers' rights and interests, then although this matter has nothing to do with Li Jiaqi himself, consumers are likely to put their first impression on Li Jiaqi, which will have some negative effects on Li Jiaqi.
Third, in order to bring greater benefits to ourselves.
Because if Li Jiaqi registers his own voice as a trademark, his own voice can only be used by himself. It is impossible for others to imitate and steal. In this way, we can not only protect our own rights and interests, but also strive for greater interests for ourselves. If others want to sell it in Li Jiaqi's voice, they need to pay for the right to use the trademark, which can also bring some income.
