When there is an objection to trademark registration, it can be handled through the following steps:

1. Objection: After the trademark registration is completed, anyone thinks that there is a problem with the registration of the trademark or If there is a conflict, you can file an objection with the corresponding trademark registration agency. Objections usually need to be filed within a certain time limit, which varies according to the regulations of different countries/regions.

2. Preparation of objection materials: Before raising an objection, prepare sufficient materials to support the objection position. This may include trademark search reports, evidentiary materials, legal basis, etc. to prove that the trademark registration conflicts or does not meet legal requirements.

3. Submission of opposition application: Submit the prepared opposition application materials to the corresponding trademark registration agency. Make sure to submit your application in accordance with the prescribed format and requirements and pay the appropriate fees, if any.

4. Opposition review: The trademark registration agency will review the opposition application. They will assess the legality of the objection and the credibility of the evidence, communicate with the trademark registration applicant and listen to statements from both parties.

5. Opposition decision: The trademark registration agency will make a decision based on the review results of the opposition application. They may reject the objection and maintain the trademark registration; or they may accept the objection and cancel or modify the trademark registration.

6. Appeal: If you are not satisfied with the trademark registration authority’s opposition decision, the legal systems of some countries/regions may allow you to appeal the decision. Within the specified time limit, an appeal application can be submitted to the corresponding appellate authority and relevant evidence and reasons can be provided.

Please note that the specific procedures and requirements for trademark registration opposition may vary from country to country. In specific cases, it is recommended to follow the country's trademark laws and trademark registration authority's guidelines, and consult a professional trademark agency or lawyer for accurate information and guidance.
