Well-known trademarks, well-known trademarks and well-known trademarks have both similarities and differences, and are closely related. 1, Similarity Well-known trademarks, well-known trademarks and well-known trademarks, as "famous trademarks", have many similarities. For example, they are all recognized by certain institutions and procedures, and they are all recognized in accordance with relevant regulations and standards, so they are more special and famous than ordinary trademarks. 2. Distinguishing well-known trademarks, well-known trademarks and well-known trademarks also have significant differences, which are mainly reflected in the following aspects: First, the accreditation agencies are different. Well-known trademarks shall be recognized and protected by the Trademark Office of the State Administration for Industry and Commerce (hereinafter referred to as the State Administration for Industry and Commerce), the Trademark Review and Adjudication Board or the designated people's court at or above the intermediate level. Famous trademarks are usually recognized and managed by institutions authorized by the people's governments of provinces, autonomous regions and municipalities directly under the Central Government. Well-known trademarks are generally recognized and managed by institutions authorized by the people's governments of prefecture-level cities. Second, according to different legal provisions. Well-known trademarks are recognized according to relevant international conventions, trademark laws, judicial interpretations and departmental rules. The identification of famous trademarks shall be based on the local regulations or local government regulations of provinces, autonomous regions and municipalities directly under the Central Government. Well-known trademarks are recognized in accordance with the provisions of prefecture-level municipal governments. Third, the criteria or conditions for identification are different. For example, well-known trademarks must be known to the relevant public nationwide. Well-known trademarks and well-known trademarks shall be known to the relevant public in this province, autonomous region, municipality directly under the Central Government or local city. The situation in each province, autonomous region, municipality directly under the Central Government and prefecture-level city is different. Fourth, the requirements for trademark registration are different. Well-known trademarks can be registered or unregistered, while well-known trademarks and well-known trademarks are usually registered trademarks. Fifth, the scope of protection is different. Well-known trademarks can be protected not only at home, but also internationally. Famous trademarks and well-known trademarks are protected in this province, autonomous region, municipality directly under the central government or prefecture-level cities. Well-known trademarks can be protected across categories and fields, but well-known trademarks and well-known trademarks do not have this treatment. 3. The relationship between well-known trademarks, well-known trademarks and well-known trademarks have certain relevance. First, a well-known trademark can be used as other documents to confirm the public's awareness of the trademark or to prove that the trademark is well-known. Well-known trademarks can also be used as other documents to prove the well-known trademarks. Second, the three can also be transformed into each other, because the reputation and popularity of each trademark are constantly changing with the passage of time or the changes in the way trademark users use it. Well-known trademarks and well-known trademarks can gradually evolve into well-known trademarks, and well-known trademarks may also degenerate into well-known trademarks, well-known trademarks and even ordinary trademarks. In China, ordinary trademarks, well-known trademarks, well-known trademarks and well-known trademarks are in the shape of pagodas, and well-known trademarks are at the top of the tower.
