Trademarks can be divided into manufacturing trademarks and sales trademarks according to user classification. A manufacturing trademark refers to a trademark used or registered by a manufacturing enterprise. Its user is the producer of the goods. This kind of trademark is used on its own products to indicate who made the product. It is also called an "industrial trademark". Sales trademarks are trademarks used by commodity operators on the goods they sell to indicate who operates the goods. This kind of trademark promotes the logo of the product seller, so that the products it sells can compete with other products in the market, so it is also called a "commercial trademark".
