The principle for judging the identity and similarity of trademarks is: 1. Based on the general concern of the relevant public, it is necessary to compare not only the whole trademark, but also the main parts of the trademark, and the comparison should be carried out separately in the state of isolated 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 the trademarks are similar, we should consider the distinctiveness and popularity of the registered trademarks. 3. The approximate query of trademark registration is very important, but it is also very complicated. This is a technical job, and it takes a long time to accumulate to increase the success rate of judgment.
