Registered Chinese and English combination trademarks can be used separately, but cannot be marked. Even if used separately, it has no legal significance and is equivalent to an unregistered trademark. If you want to use the trademark separately, you must apply separately. Otherwise, the trademark will be revoked by the Industrial and Commercial Bureau or involve trademark infringement due to incorrect use of the trademark.

It is better to apply for combined trademark registration separately, ① which can improve the success rate of trademark registration. Separate registration can effectively improve the approval rate of trademark applications. For trademarks that are a combination of elements such as Chinese trademarks, letter trademarks, and graphic trademarks, the Trademark Office will separate them and examine each component separately. As long as one of the elements is the same or similar to a trademark previously applied for by others, the entire Combination trademarks will be rejected. Even if a certain trademark is rejected for separate registration, it will not affect other parts of the application.

② It can improve the efficiency of trademark registration review. Each part of a combination trademark must be examined one by one, which means that the examination speed is much slower than that of a separate application, resulting in a reduction in examination efficiency. Applying separately will not affect each other. ③ It can make the use of registered trademarks more flexible. Once the combination registration is approved, the trademarks can only be used in accordance with the combination of the trademarks at the time of registration. However, each element of a trademark applied for separately can be used independently or combined in any combination, making it more flexible in use. ④ Conducive to protecting trademarks and effectively safeguarding rights. Separate registration can not only increase the probability of successful registration, but also effectively enhance the defense capabilities of the trademark. In a combination trademark, if the infringer only uses a certain part of the combination trademark, the court may not necessarily determine that it constitutes infringement. However, trademarks registered separately are independent and distinctive, making it easier to defend rights in the event of infringement.
