Patent Drawings

A patent application or patent may contain drawings, also called patent drawings (or patent illustrations), illustrating the invention.

We can assist you with the preparation
of Patent Illustrations for your Patent Application

patentedPatent Drawings don’t always necessarily need to form a part of your Patent Application – but very often they provide important information that can’t easily be described in text alone – and in some countries at least one patent illustration is required.

In reality, you should consider how many patent drawings are necessary in order to demonstrate what you have invented.

Most patent applications have at least several sheets of drawings, with each sheet routinely having multiple views of the invention. You may need to show various views (top, bottom, right, left, etc.) and you may need to break down the invention and show drawings of one or more of the component parts.

The drawings must show every feature of the invention specified in the claims, and it is required by Patent Office rules to be in a particular form.
