1. Increased risk. The risk is greater when applying together, and vice versa when applying separately. For trademarks that are a combination of Chinese trademarks, letter trademarks and graphic trademarks, the Trademark Office will separate them and examine them separately. As long as one element is identical or similar to the same element in someone else's trademark, the trademark will be rejected as a whole.

2. Inconvenient to use. Combined application is inconvenient and inflexible, but separate application is the opposite. If applied in combination, they must be used together and cannot be split or changed. However, applying separately is very flexible and can be used independently or in any combination. For example: NIKE, graphics, Nike, can be separated or combined. It is very convenient to use on packaging, door headers and products. If applied in combination, it will be very large and unsightly when used on shoes.

3. Time increases. The examination speed of trademarks applied in combination is relatively slower than that of trademarks applied separately, because each part must be examined separately, while separate applications do not affect each other.

4. Cost issue. The combined application fee is less, and the individual application fee is more. The combined application fee is one trademark, and separate applications will cost a few cents. Although the apparent cost has increased, the intangible benefits produced during actual use are far greater than the cost of separate registration.
