Copyrights that are already granted in countries that are part of the Berne Convention, of which Vietnam is a member, are already granted in all other treaty countries. The convention also means that you as the creator automatically own the copyrights without the formal need to register them. However, it is still advisable to register copyrights in Vietnam with the National Copyright Office of Vietnam (NCO), or the Department of Culture, because this will make court proceedings easier if you ever need to enforce these rights before a Vietnamese court. Copyright certificates are also required in certain enforcement procedures. The NCO is required by law to notify you in writing whether or not the copyright has been granted within 15 working days from the date of receipt of a valid application.
