Successfully registering a trademark and obtaining a registration certificate does not mean that the possibility of infringement is completely eliminated. Even if a trademark is successfully registered, there are still other situations that may infringe upon your trademark rights.

The following are some situations that may lead to continued infringement after successful trademark registration:

1. First use right: Trademark registration is usually based on the first-to-file, first-served principle, but in a certain In some countries or regions, those who have used the trademark in relevant fields before you registered the trademark may have certain rights of prior use. This means that even if your trademark is registered, if someone can prove that they have used the same or similar trademark in that field before you, they may have the right to continue to use it.

2. Similar trademarks: Although your trademark has been registered, there is still a risk of confusion with other trademarks that are similar to yours. If another trademark looks, sounds, or means very similar to yours, it may cause confusion among consumers and infringe on your trademark rights.

3. Unregistered trademark: Trademark registration is only valid in the country or region where you registered. If someone uses the same or similar logo as yours in another country or region but does not register the trademark, they may infringe on your trademark rights, especially if you plan to expand your business to other regions.

4. Malicious behavior: Some people may deliberately infringe on your trademark rights and make profits through counterfeiting, misappropriation of trademarks or other fraudulent means. These malicious actions may require legal action to protect your trademark rights.

Therefore, trademark registration is only an important step to ensure that you legally own the trademark rights, but it does not completely eliminate the possibility of infringement. In order to protect your trademark rights and interests, it is recommended that you monitor and maintain it regularly and take appropriate legal action when infringement is discovered.

Please note that trademark laws and infringement regulations may vary from country to country. If you require specific legal advice, it is recommended that you consult a local trademark attorney.
