In some countries and regions, the ownership of trademarks is usually granted to individuals or enterprises that use trademarks for the first time, that is, the principle of first use and first registration. This means that even if there is no registered trademark, as long as the trademark is used for the first time in a specific field, it may be regarded as the legal owner of the trademark.
But in other places, trademark registration is the main means to establish rights, that is, the principle of first registration first acquisition. In this case, unregistered trademarks may be vulnerable to infringement charges.
It is worth noting that some countries and regions may also take measures related to the time of use to allow trademarks to be used within a certain period before registration in order to obtain legitimate rights and interests.
Generally speaking, whether the use of a trademark before registration is infringement requires comprehensive consideration of relevant laws and regulations, including the principle of first use, the principle of first registration and other possible rights protection mechanisms.
