Legal analysis: The Certificate of International Registration of Trademarks is a certificate issued by the International Bureau to the applicant for international registration of trademarks, which records the relevant matters in detail. Usually, it is sent directly to the applicant (agent) by the International Bureau within 4 months from the date of application. Because it takes one year for international registration in accordance with the Agreement and one and a half years for international registration in accordance with the Protocol, the country designated for territorial extension may reject the applicant's application for territorial extension after the International Bureau issues the applicant with the Certificate of International Registration of Trademarks. Therefore, the Certificate of International Registration of Trademarks can only prove the fact that the applicant has registered the trademark internationally, but it cannot prove that all the countries designated for protection in the Certificate of International Registration of Trademarks are valid. A legal document that can prove that the country designated by the applicant for international registration of trademarks is effective is the International Register of Trademarks, which has legal effect and is kept in the International Bureau. After receiving an application for international registration that conforms to the Detailed Rules for the Implementation of madrid agreement concerning the international registration of marks and its Protocols, the International Bureau shall register in the international register book and issue the Trademark International Registration Certificate to the applicant for trademark registration. The Trademark International Registration Certificate shall be sent directly to the International Registration Office of the Trademark Office, which shall forward it to the applicant or trademark agency. It should be noted that the applicant must fill in the address clearly (mailing address can be added), and if the applicant's address changes, it should be changed in time.
