First, let’s take a look at how a trademark is defined:

A product trademark is the mark of a product. It is the most basic form of expression of a trademark, and what is usually called a trademark mainly refers to a commodity trademark.

Once a product trademark is registered by a production (sales) enterprise, the enterprise has the exclusive right to use the product trademark and is protected by law.

Commodity trademarks can be divided into industrial trademarks of commodity producers and commercial trademarks of commodity sellers.

Industrial trademarks: refer to trademarks that clearly indicate the producer of goods (also called manufacturing trademarks). This kind of trademark has the same meaning as a "manufacturer's name", which allows the goods produced by the commodity producer to have the producer's mark, thereby distinguishing it from other producers, and conveying to consumers the meaning of the producer of a certain commodity. Information and sources.

Commercial trademark: refers to the trademark used by sellers (operators) to sell goods (also called sales trademarks). The focus of this kind of trademark is to promote the mark of the seller of the goods, not the producer of the goods. Those who use such trademarks are often commercial enterprises with high reputation and strength. They produce goods with their own trademarks under OEM brands, thereby ensuring some credibility to consumers.

Under normal circumstances, there is no distinction between the above two trademark types when used, and they are both used as commodity trademarks.

What I mainly say is: as a kind of logo, a trademark is used to make the goods produced by commodity producers have the mark of the producer, so as to distinguish them from other producers and provide consumers with Conveys the information and origins of the producer of a commodity.

So not all products must have a trademark.
