Trademarks emerged with the occurrence and development of the commodity economy. The earliest trademarks were mainly used to distinguish the manufacturer of the product. Generally, only the name of the product manufacturer was engraved on the product. Later, shops and workshops appeared, and the marking of goods became increasingly complex. In some cases, in addition to the name of the manufacturer, there are also signs indicating the name of the shop and workshop. Later, there were pattern trademarks, word trademarks and trademarks using both text and pictures. In Europe, trademarks originated from nomadic tribes in Spain. They branded their livestock and became a mark to distinguish their own livestock from that of others when exchanging goods. By the 13th century, European commercial guilds were generally prevalent and the commodity economy developed rapidly. Each guild began to use its own specific seal (ie trademark). Today, there are more and more types of trademarks, and they are becoming more and more eye-catching.
