international trademarks need to be maintained after successful registration! For example, countries such as the United States and the Philippines have to submit an oath in the fifth-sixth year and the third year to provide evidence to prove that the trademark is still in use. If the trademark is not submitted within the time limit, it will be invalid. In addition, we should also pay attention to whether the trademarks applied by others in the future are the same or similar to those registered by you, and raise objections in time to protect our trademark rights and interests.
