Patents actually come in two different forms. The patents described in this section are utility patents, a type of patent that protects the intellectual property around how an invention functions.

Inventors may also take advantage of design patents. These patents cover the appearance of an invention and last for only 15 years. They do not protect the idea of an invention, only the form of the invention, so they are generally seen as a weaker form of intellectual property protection than utility patents, but they are also easier to obtain.
