1. Advantages of Madrid trademark registration 1) Simple procedures Trademark applicants can generally apply for trademark registration to all parties that have joined the same treaty except their countries of origin by submitting an application in one language (French, English or Spanish) and paying a fee once (at present, only the fees charged by Japan and Ghana are divided into application fee and registration fee twice), thus eliminating the need. (2) The practice of low cost shows that it is cheaper to apply for international trademark registration through Madrid system than to apply for trademark registration one by one in each country. The more countries apply, the more cost savings will be. The simplicity of the procedures and the low cost are also reflected in many procedures after the application for international registration. For example, applications for change, transfer, renewal, deletion and cancellation only need to submit one application and pay one fee. (3) Reduce the workload of the trademark authorities of the contracting parties. The classification of goods and services and the formal examination of the application for international registration of trademarks are completed by the International Bureau of the World Intellectual Property Organization (hereinafter referred to as the International Bureau), which reduces the workload of the trademark authorities of the contracting parties to some extent. In addition, the International Bureau is responsible for the issuance of international registration announcements, exempting all competent authorities from the obligation to announce international registered trademarks again. The collection and distribution of international registration fees are also completed by the International Bureau, which also reduces the workload of the competent authorities. 2. Disadvantages of registration: 1. There is no trademark certificate, only one certificate. If you take the certificate and go to Japan, South Korea or other countries to apply for a certificate, you will have to incur other expenses. 2. The follow-up procedure is complicated. If the trademark is rejected or objected, it needs to entrust an agency to reply again, resulting in other expenses. 3, must be based on domestic trademark registration, that is, you must first apply for or register a trademark in China. 4. The principle of "center attack", within 5 years from the date of registration, the basic trademark is revoked or rejected, and its effect is in all designated countries. 5. It is difficult to determine the specific time of protection (that is, when the applicant successfully registered). There is no certificate for registration in Madrid, only the acceptance certificate. 6. Sometimes the documents sent are in French.
