After the trademark registration, the registrant obtains the exclusive right to use the trademark, and others use the same or similar trademark on similar goods or services, which may constitute infringement. The main function of a registered trademark is to protect the rights and interests of the trademark owner and ensure that others will not use similar trademarks on the same or similar goods or services.

Specifically:

1.** Exclusive right: * * Trademark registration gives the registrant the exclusive right to use the trademark in the registered area, and others may not use the same or similar logo as the registered trademark on similar goods or services.

2.** Legal protection: * * Trademark registration enables the trademark owner to legally sue for infringement, and requires the infringer to stop using similar trademarks and claim compensation for losses.

3.** Validity period: * * Trademark registration usually has a certain validity period and needs to be renewed before it expires. Long-term effective protection requires continuous trademark maintenance.

Generally speaking, trademark registration provides a stronger legal status for trademark owners and prevents others from using similar trademarks on similar goods or services, thus maintaining the uniqueness and brand value of trademarks.
