Famous branding is a phenomenon of unfair competition. It mainly refers to registering a famous trademark as one's own company trade name in order to confuse the company name and the brand name, trying to make consumers mistakenly think that the famous brand is the name of the company. The company produces to expand sales and gain profits. Originally it has nothing to do with famous brands, but it is necessary to use trademarks and company names to associate one's own company or products with famous brand products. This phenomenon of "famous branding" that can easily lead to misunderstanding and confusion among consumers is not only serious. It infringes upon the legitimate rights and interests of consumers and directly affects the sound and orderly development of the market economy. It has become the common sense of people from all walks of life to curb the phenomenon of following famous brands, protect intellectual property rights, and protect the legitimate rights and interests of consumers.
