After the successful registration of a trademark, the trademark owner obtains the exclusive right to use the trademark, that is, others cannot use the same or confusing trademark on the same or similar goods or services. But trademark right and business license are two different concepts, and trademark right does not directly affect the use of business license.

Business license is a document to prove the legal operation of an enterprise, while trademark registration is to protect the exclusive right of a trademark in commercial activities. Even if the trademark registration is successful, others have registered a business license with the same name before. Generally speaking, this will not be directly affected by the trademark law.

However, some situations may require attention:

1. Priority principle: In business activities, the principle of first registration is usually applied. If others register the same or similar trade name before your trademark registration, they may have priority.

2. Local regulations: In some places, there may be specific regulations that require enterprises to avoid conflicts with existing enterprises when registering locally.

3. Brand image: Although trademark registration can provide strong legal protection, it is suggested that enterprises should also pay attention to their brand image and try to avoid confusion or disputes with other enterprises in order to safeguard their goodwill.

Generally speaking, the relationship between trademark right and business license right is complicated, and the specific situation may be affected by laws, regional regulations and the principle of priority. If you are worried about possible conflicts, it is recommended to consult a professional intellectual property lawyer for specific legal advice.
