Paten is like a very special sticker that a person can get when they come up with something new and different. It's like getting a gold star in school, but for inventing something!
Let's say you come up with a new toy that no one else has thought of before. You can go to a special office and fill out some papers to apply for a paten. This tells everyone else that you're the one who came up with that toy and they can't make it or sell it without your permission.
It's kind of like when you draw a really cool picture and write your name on it so everyone knows you made it. When you get a paten, it's like you're putting your name on your invention so people know it's yours.
Having a paten is important because it helps protect your invention and make sure you get the credit and money you deserve for creating something special.
