PatentLeft is a way that people can share ideas and inventions with other people without needing to get a patent. A patent is an official government document that gives a person or company the legal right to be the only one who can make and sell a product or invention. But patents are expensive, so PatentLeft lets people give away their inventions for free. This means that other people can then use the idea or invention without having to pay or get permission from the original inventor. This encourages creativity and innovation and helps new ideas to spread more quickly.
