Legal analysis: Trademark approximation refers to a trademark that is similar to the font, pronunciation and meaning of words, or the composition and color of graphics, or the overall structure of words and graphics, which easily confuses consumers about the source of goods or services.

legal basis: according to article 28 of the trademark law, if a trademark applied for registration does not conform to the relevant provisions of this law or is the same as or similar to a trademark already registered or preliminarily approved by others on the same or similar goods, the trademark office will reject the application and refuse to register it. Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Patent Infringement Disputes (II) The provisions of Article 9: The trademarks specified in Item (1) and (2) are the same, which means that there is basically no visual difference between the trademark accused of infringement and the registered trademark of the plaintiff. Trademark approximation as mentioned in Item (2) refers to that the font, pronunciation, meaning, graphic composition and color of the trademark accused of infringement are similar to those of the plaintiff's registered trademark, or the overall structure after the combination of its elements is similar, or the three-dimensional shape and color combination are similar, which is easy for the relevant public to misunderstand the source of the goods or think that its source has a specific connection with the goods registered by the plaintiff.
