Pictures for Patent
are two acceptable types of drawings that can be sent with a
utility patent application.
Black ink. These are normally the required type. India ink or a
type that will produce solid black lines must be used.
Color drawings are accepted only when necessary and after filing
an explanation telling why the color is important to the patent
may also be submitted, but normally are not permitted in utility
patent applications. Find out more about the rules that apply at
the U.S. Patent
and Trademark Office Home Page.
