The United States Patent And Trademark Office

A patent protects your invention.

A patent for an invention is a grant of property rights by the U.S. Government through the U.S. Patent and Trademark Office. The patent grant excludes others from making, using, or selling the invention in the United States.

Marking of an article as patented, when it is not, is illegal and subject to penalty.
