Searching for global trademarks with one click is a bit demanding, and it is not possible at present.
Trademark protection is regional, which is divided into countries and regions. Different countries have different protection rules. Each country has its own trademark search website, but there is no unified website to enter global trademarks and realize one-click search. The stupid way is the only way, that is, to find the search website of each country and save it.
the best way to avoid infringement is to do a good job of research and analyze whether there will be infringement before making this product. In this way, we can take a step and open our arms to do cross-border e-commerce.
if you have any specific trademark questions, please leave a message in the comment area!
