The Trademark Law clearly stipulates some names and logos that are prohibited from being used, for example, geographical names cannot be registered as trademarks. If you register a foreign trademark, you can't violate local taboos, for example, some countries forbid using numbers as trademarks, and the United States forbids using precious animals as trademark graphics, and so on.
it is desirable for a company to have a high brand awareness. however, if the brand goes too far, it may get burned, lose its distinctiveness and become a common name or symbol of a certain product. Such as "USB flash drive", "zipper" and so on, are typical examples of weakening trademarks into common names. Trademarks such as "Weibo" and "Double Eleven" that have appeared in recent years are also in danger of being weakened into common names.
In this case, China's Trademark Law stipulates that any unit or individual may apply to the Trademark Office to cancel the registered trademark.
