Associated Mark refers to a trademark owner registering several similar trademarks on the same goods, or registering several identical or similar trademarks on different goods of the same category. , these trademarks that are similar to each other are called joint trademarks. Among these trademarks, the one registered first or mainly used is the main trademark, and the rest are joint trademarks. Due to the special role and function of joint trademarks, if one of the trademarks is left idle, it will not be revoked by the national trademark authority. Due to the similarity of the joint trademarks to each other, the joint trademarks may not be divided, used or transferred across categories.

1. The subject of the joint trademark is also the owner of the original trademark, and the two should be consistent. The goods for which the joint trademark is approved are identical or similar to the goods for which the original trademark is approved. Moreover, the joint trademark should be similar in sound, shape and meaning to the original trademark.

2. Joint trademark registration is not for use, but to form a protective perimeter for the main trademark.

3. Joint trademarks can be registered separately, but each trademark cannot be transferred separately. The entire joint trademark must be transferred together, and the same is true for the joint trademark use license.

4. Each trademark in the joint trademark is relatively independent. The cancellation or termination of one of the trademarks will not affect the validity of the other trademarks.
