14. Julio secured a copyright registration for a drawing of a light box. Julio used the drawing for his advertisements indicating the new internal electronic design features of the light box. Ten years after the registration of the copyright, Julian decided to manufacture and sell a light box with the same internal electric design features as the light box drawing created by Julio. However, the physical appearance of the light box manufactured by Julian is different. Julio objected to the manufacture by Julian of the light box on the ground that he (Julio) is the inventor of the light box design. Is the objection of Julio valid? Discuss.
