A patent is a government grant that gives an inventor the right to stop others from making, using, or selling an invention for a limited time. The United States Patent and Trademark Office examines applications and issues patents, and federal courts handle disputes. Congress sets the rules.

Readers usually want to know what can be patented, how to apply, and how the process works. They ask how claims define an invention, how searches for earlier inventions are done, how long and how costly the process is, and what a patent does and does not protect.
