Trademark registration inquiry can improve the success rate of trademark registration, and the principles for judging the similarity of trademarks are as follows:

1. Based on the general attention of the relevant public, it is necessary to compare both the whole trademark and the main parts of the trademark, and the comparison should be carried out separately in the state of isolation of the comparison objects; The approximation in judging trademark infringement is not limited to the approximation of the whole trademark, but also includes the approximation of the main part.

2. When judging whether a trademark is similar, the distinctiveness and popularity of the registered trademark should be considered. The Supreme People's Court applied the above principle of judging trademark similarity when hearing this case.

3. Take the general attention of the relevant public as the standard, compare the trademark in dispute as a whole and the main parts. In the case of trademark infringement disputes, whether the accused infringing trademark is similar to the registered trademark claiming rights should be comprehensively analyzed and judged whether the whole or the main part of the trademark is likely to be confused in the market based on the specific circumstances such as the salience and market popularity of the trademark or its constituent elements, and the consideration and comparison of the font, pronunciation and meaning of words, the composition and color of graphics, or the combined structure of various constituent elements. If the whole or main part of it has the possibility of market confusion, it can be considered to be similar; Otherwise, it is not considered as an approximation.

4. When identifying the similarity of trademarks, consider the distinctiveness and popularity of the trademark requested to be protected. The more prominent and well-known a trademark is, the greater the possibility of being confused and mistaken, and therefore the greater the intensity of its protection. This is because for a registered trademark with a well-known degree in a specific market, giving it a strong legal protection commensurate with its well-known degree is conducive to encouraging the winners of market competition, encouraging legitimate competition and purifying the market order, and preventing others from improperly attaching themselves to its commercial reputation, thus effectively promoting the orderly and healthy development of the market economy.
