After the trademark is successfully registered, your trademark rights are protected by law, which means that you have the right to prevent others from using the same or similar logo as your trademark in the same category. Trademark rights and business licenses are two different concepts. Trademark rights do not directly involve the use of business licenses.

If someone has previously applied for a business license using the same or similar trademark name before you registered your trademark, according to the principles of trademark law, your trademark registration will not automatically invalidate the business license. However, if your trademark is similar to its trademark name, you can protect your trademark rights by exercising trademark rights.

In this case, you can take the following measures to safeguard your trademark rights:

1. Trademark infringement complaint: If you find that someone is using your trademark in the same category If you have the same or similar logo, you can file a trademark infringement complaint with the relevant trademark administrative agency or court and request the other party to stop using the infringing logo.

2. Trademark rights litigation: If the trademark infringement dispute cannot be resolved through negotiation, you may consider filing a trademark infringement lawsuit to protect your trademark rights through legal means.

Please note that trademark infringement and the right to use a business license are two different legal issues, so in specific cases, it is recommended that you consult a professional intellectual property lawyer to obtain accurate legal advice and guidance.
