The landlord's question is not very clear. What is the international use of trademarks? Trademarks are only used to indicate the source of products and can be used at will in theory. I wonder what the landlord means: can a trademark be directly protected internationally after it is successfully registered in a country? In this regard, the answer is no, because trademarks are regional and need to be registered separately to be protected. For example, registered trademarks in China can only be protected in China. If a trademark wants to be protected in Japan, it should be successfully registered in Japan.
