The trademark registration certificate has the following functions:

1. Legal protection: The trademark registration certificate is the legal proof of trademark ownership. It confirms that you, as the legal owner of the trademark, have the right to use and protect the trademark in the country or region where it is registered. A trademark registration certificate provides legal protection, giving you the right to sue infringers and defend your trademark rights.

2. Priority of trademark rights: The trademark registration certificate can be used as evidence that you enjoy trademark rights from the date of trademark application. In trademark rights disputes, having a trademark registration certificate can prove that you applied for and registered the trademark before other similar trademark applicants, thereby giving priority to trademark rights.

3. Trademark publicity and commercial value: Trademark registration proves the legality and uniqueness of the trademark, which can increase the publicity and commercial value of the trademark. As an asset of a trademark brand, a trademark registration certificate can enhance consumers' trust and recognition of the brand and improve the brand's market competitiveness.

4. Trademark licensing and transfer: The trademark registration certificate can be used as an important document for trademark licensing and transfer. If you plan to license your trademark to others or transfer your trademark to others, the trademark registration certificate can prove that you are the legal owner of the trademark and ensure the legality and rights of the transaction.

5. International protection: A trademark registration certificate can facilitate you to apply for a trademark in other countries or regions. Some countries or regions require a previously registered trademark certificate as proof when applying for a trademark. The trademark registration certificate can be used as your evidence during the international trademark registration process.

In short, the trademark registration certificate is the legal certificate of trademark ownership and plays an important role in protecting trademark rights, increasing trademark value and facilitating trademark transactions.
