What to Expect From an Invention Drawing

Invention drawings are specially made to illustrate an inventor’s invention. These drawings are typically prepared for the US patent application, as well as to show how the invention fits in with the “format” of the patent specification. When the inventor is nearly ready with his invention, the drafting process begins. The invention drawing contains the overall layout of the invention including graphics, text, and elements needed to support the claims.

There are some basic steps that should be followed for the drawing to ensure accuracy. The drawing should include: a drawing of the invention and all its components, including: a model or prototype if one was previously made; a description of the invention including all its features, functions, and any unique or distinguishing features that make the invention “unique”; and any data that will support the examiner’s decision as to the scope of the claim being filed. All of the invention’s components should be highlighted in a way that will indicate their importance. Also, the invention should be designed so that it can be readily described by using the appropriate language, such that the invention is easy to understand and describe. Finally, all claims should be written in a way that does not limit the legal protections of the invention but also so that they can be supported by the claims themselves.

The purpose of the invention drawing is to provide a tool for inventors and their advisors as they work on patent applications. It provides a visual representation of the invention and allows the advisor to consider each part of the invention in relation to the claims, and the invention should be complete so that it can easily be explained. In addition, the invention drawing allows the inventor to modify the invention without fear of going against the stipulations of the patent. In fact, modifications may be submitted after the patent application has been filed, if and when appropriate to do so.
