Invention registration system used to protect inventions with less inventive range than those protected by patents. They consist, for example, in giving an object a configuration or structure from which some usefulness or practical advantage is derived. The device, instrument or tool that can be protected by the utility model is characterized by its utility and practicality and not by its aesthetics, as occurs in industrial design. The scope of protection for a utility model is similar to that conferred by a patent; however, the duration of the utility model is ten years from the filing of the application.
