Well-known trademark refers to a trademark that is widely known in the commercial field and has a high reputation. Such trademarks are usually closely related to a famous brand or well-known enterprise, forming brand awareness and brand loyalty.

After years of accumulation and marketing, such trademarks have successfully formed super-high brand value in the minds of consumers.

The significance of a well-known trademark is that it represents a high trademark value and consumer awareness. With this trademark symbol, enterprises can communicate and trade with customers more conveniently, and can also influence consumers' choice behavior with the help of this brand influence to improve their market share and image.

Therefore, well-known trademarks are an important part of enterprise brand value and market position.

The formation of famous trademarks requires long-term marketing and product execution of enterprises. At the same time, enterprises need to have a high sense of social responsibility and have close ties with consumers. With the support of these conditions, enterprises can create famous trademarks with global competitiveness and popularity, thus effectively promoting the development and growth of enterprises in the market. In marketing activities, enterprises should make comprehensive use of various resources, combine quality, brand, price, service and other factors, create more high-quality products and services, and continue to promote them.
