Yes. You can file an international registration application for a trademark at the same time as you file the national application. However, if the national application is rejected or deemed inadmissible, the Industrial Property Division will inform WIPO, which will then cancel the international registration. In the Principality of Monaco, registration is not officially confirmed until a minimum of one month and one day after filing, and so it is recommended to wait for your trademark to be registered nationally before then applying for an international extension.
