Patent
From Wikipedia, a free encyclopedia written in simple English for easy reading.
A patent is when someone has a new idea. They then write the idea down, and go to an office, where they say the idea is new.
The office will then check, and if the idea is really new, they can use their invention for a long time. If someone else comes up with the same idea, and wants to make a product from it, they can sue him or her. He may have to pay royalties to use the idea.
This short article needs someone to make it better.
