Agreed, "In all countries that are members of the Berne Convention, copyright is automatic and need not be obtained through official registration with any government office. Once an idea has been reduced to tangible form, for example by securing it in a fixed medium (such as a drawing, sheet music, photograph, a videotape, or a computer file), the copyright holder, or rightsholder, is entitled to enforce his or her exclusive rights."
