there is no doubt that to maintain the commercial appeal of the logo, on the one hand, it is necessary to maintain the stable quality of the goods, on the other hand, it is also necessary to maintain the distinctiveness of the logo. Once it cannot indicate the source of the goods or be used to distinguish the goods of other operators, even if the logo is still attractive, it is only for its own design or color, and it is not helpful to promote the sales of specific goods. To make matters worse, if the consumer is confused, or misled or deceived by similar signs, then he is likely to buy inferior products from other operators by mistake, thus damaging the goodwill of the real trademark owner. Therefore, trademark owners do everything possible to maintain the distinctiveness of trademarks, thus maintaining their own goodwill. Trademark distinctiveness has gradually become the core of trademark protection. Since the mid-2th century, with the prosperity of mass media and advertising industry, the function of trademark is no longer limited to indicating the source of goods, or indicating the quality and reputation. It has begun to have multiple functions: it represents a culture, an experience, and becomes the characteristics of personal identity and taste. Many times, consumers often buy a specific product not because it originated from a specific producer or has a certain quality level, but because consumers think it is a representative of a culture and a fashionable experience. For example, "Marlboro", consumers may not know the quality of clothes marked with "Marlboro", but consumers may still want to buy the clothes of this brand because of the meaning of Marlboro, because Marlboro represents the manly spirit of pioneering in the western United States. What does this question mean? It shows that the buyer's desire to buy a commodity not only comes from the commodity itself, but sometimes it actually recognizes the spirit and image represented by the brand.
