The process of trademark registration among Madrid Union member states is divided into application preparation, payment of fees and certificate collection. The relevant application documents that should be submitted for application preparation are as follows: First, the enterprise needs to fill in a Chinese international registration application with an official seal and fill in a foreign international registration application with an official seal or signature; secondly, the enterprise needs to provide two trademark drawings. If it is a color trademark, two copies of the color trademark drawings must be attached. If a trademark agency is entrusted to handle the matter, a trademark agency power of attorney should be submitted. If you choose to apply in a single country, prepare the following materials: In Bulgaria, the materials required for an enterprise to submit a trademark application include the applicant's name, address, business scope, trademark drawing, power of attorney signed by the applicant, and list of goods and services. If you are a foreign applicant, you need to provide a corporate business license or related certificates.

When the Trademark Office receives the fully prepared application documents, after registering the date of receipt and assigning the application number, it will calculate the fees required by the applicant and issue a fee notice to the applicant. . The applicant shall pay the relevant fees to the Trademark Office 15 days after receiving the fee notice. After completing this step, the Trademark Office will apply to the International Bureau. After receiving the remittance, the Trademark Office will submit the application to the International Bureau. If the Trademark Office does not receive the remittance after 60 days, it will return the application documents and other attachments to the applicant, and will no longer retain the application date and application number. After everything is ready, the International Bureau will receive the application from the China Trademark Office. After confirming that it meets the international registration application, it will register it in the International Register and issue a trademark registration certificate to the trademark registration applicant.
