In December 2019, a client contacted us, with whom we have worked on other projects over the past two years. Our client is an applicant of two national trademarks before the Patent Office of the Republic of Bulgaria. Our client has recorded a change in the name and address at the Trade Register, which is why we were hired to register the change in order to fulfill the requirements of the legislation. We prepared the necessary documents for recording the changes, paid the state fees, and filed the documents at the Patent Office. After a few days, the changes were successfully recorded. We have provided a certificate to the client for the change in the name and address of the applicant for both trademarks, with which we successfully completed this project.
