Patent Drawings

All patent applications require at least one drawing with very few exceptions. Design patents usually require at least six to show each perspective.

The majority of patent drawings require reference numbers to identify elements, components, and parts. These numbers are used throughout the written description to describe and explain how the invention works and is used. It is very important to correctly number these elements in a sequential and consistent manner.

About Patent Drawings

The USPTO has strict guidelines for technical drawings that must be followed when submitting an application. Drawings that do not conform to these standards may be rejected.

The purpose of a drawing requirement is to visually convey all of the details that describe how the invention works and is used. The written description and drawings must match.

There are several different types of drawings depending on the type of invention, or what the inventor wants to explain.

Orthogonal Views (2-D)

Perspective Views (3-D)

Other Views

Graphical techniques


These actual patents from the USPTO show one drawing from each registration to show different ways that a drawing conveys information about the written description.
