If someone has applied for a business license with the same or similar trademark name before you register a trademark, according to the principle of trademark law, your trademark registration will not automatically invalidate its business license. But if your trademark is similar to its trademark name, you can protect your trademark right by exercising it.
In this case, you can take the following measures to safeguard your trademark rights:
1. Trademark infringement complaint: If someone is found to use the same or similar logo as your trademark in the same category, you can file a trademark infringement complaint with the relevant trademark management authority or court and ask the other party to stop using the infringing logo.
2. Trademark litigation: If the trademark infringement dispute cannot be resolved through consultation, you can consider filing a trademark infringement lawsuit to protect your trademark rights and interests through legal means.
Please note that trademark infringement and the right to use a business license are two different legal issues. I suggest you consult a professional intellectual property lawyer under specific circumstances to obtain accurate legal advice and guidance.
