A Patent

Patent is when someone who invents something takes out the license, thereby restricting other people from using that invention so that they can form businesses, make a product and have full ownership.

Sometimes, the person who patents the product isn’t the inventor. But he was able to get a hold of the product and patent before anybody else did. Some say patents are good because they inspire inventors to activity; like research so that they can profit from inventions that they make. This is good for society as a whole.
