A utility model is an intellectual property right to protect inventions. This right is available in a number of national statutes, as described below. It is very similar to the patent, but usually has a shorter term (often 6 to 15 years) and less stringent patentability requirements.
The German and Austrian utility model is called the " Gebrauchsmuster", which influenced some other countries such as Japan. In Indonesia the utility model is called a "Petty Patent".
