What is a patent?

A patent is like a special permission slip from the government that says "this is YOUR invention, and nobody else can copy it" [2][3]. It's a legal document that protects your idea so you're the only one allowed to make, use, or sell it [4].

Why do patents exist?

Patents exist to reward people who come up with new and creative ideas [2]. If inventors knew someone could just steal their invention and sell it, they wouldn't want to work hard on new things, so patents encourage people to invent [4].

What can be patented?

You can patent inventions like new devices, substances, methods, and processes—basically anything new that you create [5]. But it has to be actually new, not something someone already invented [5].

How long does a patent last?

Once you get a patent, you get to keep your exclusive rights for a limited time, and you need to maintain those rights to keep them protected [1].
