Generally speaking, after a trademark is registered, the core elements of the trademark, including the characters, graphics or the combination of graphics and characters, have been determined and registered. If you want to add new elements after trademark registration, such as a new logo, you usually need to apply for trademark registration again.

The steps to add new elements may include:

1. Design a new trademark: create a design containing a new logo and ensure that it meets the requirements stipulated in the Trademark Law.

2. trademark search: conduct trademark search to ensure that the newly designed trademark does not conflict with the existing trademark.

3. submit a new trademark registration application: submit a trademark registration application containing a new logo. In the application, you need to provide detailed trademark patterns, a list of goods or services and other relevant information.

4. Waiting for examination: The Trademark Office will examine the new trademark registration application, including formal examination and substantive examination.

5. Get a new trademark registration certificate: If the new trademark application passes the examination and is registered successfully, you will get a new trademark registration certificate.

It should be noted that the change of a trademark may affect the validity of the trademark right, so it is recommended to consult a professional trademark agent or legal professional when making any trademark change to ensure the compliance and validity of the change.
