Every trademark has different rules. For example, China's trademark law stipulates the principle of prior application, that is, the trademark belongs to who registers first, not who uses it first. Moreover, there is also a blind inspection period of trademarks in China, which is also the stage of trademark submission and registration. The trademark status can't be inquired, but the applicant owns the trademark, which can't be registered.
Under the premise of "application first" principle, combined with "application first" principle, it is a practical and flexible principle of preliminary examination and approval of trademarks. So why do we often say that the trademark is registered first? So if you want a trademark, you should leave and register immediately, or buy a trademark.
