Registered copyright does not refer to a different type of intellectual property right, but to copyright that has been registered under the voluntary system of registration. Copyright is indeed an automatic right that does not depend on registration. Nevertheless, in some countries (e.g. Belgium), national laws allow registration of artistic/literary works. This voluntary system of registration is generally aimed at identifying the work and serving as evidence in court in litigation disputes (e.g. in order to prove more easily the date of creation of the work); it does not prove authorship.
