If the trademark registration is not approved, it may need to be modified. Adding letters is a possible modification method. After a trademark application is reviewed, if there are problems such as similarity with an existing trademark, lack of originality, and likely to cause confusion, the Trademark Office or relevant agencies may raise objections or refuse registration.

In order to pass the trademark registration review, you may need to make some modifications to your trademark to increase its uniqueness, reduce its similarity to an existing trademark, or otherwise meet the registration requirements under the Trademark Law. In this process, adding letters is a common modification method that can make the trademark more distinguishable.

The specific modification strategy will depend on the examination results and the specific requirements of the Trademark Office. It is recommended that you read the review result notice carefully and make reasonable modifications based on relevant suggestions. In addition, you can also consult a professional trademark agent or lawyer for more specific guidance and advice.
