Different Patent Drawing Views
An object can be viewed from a large number of view angles – for example, from the front, top back or side, etc. A single figure or drawing can show an object only from one view angle and thus all-important figures can not be shown in one figure. Many parts of the object can be hidden in a single view. Therefore, when we aim to clearly explain the inventive steps using drawing while preparing patent applications we should select the views needed to explain the disclosed subject matter clearly, without unnecessary duplication.
For ready references, conventional names of view angles are used. Common Drawing views are listed below:
- Orthogonal Views
- Perspective Views
- Isometric View
- Exploded View
- Sectional View
What Each Patent View Shows
Orthographic Views
Front, rear, side, top and bottom views show the article from selected perpendicular directions. Compare corresponding edges and features across views. Read our orthogonal and orthographic drawing guide for terminology and projection basics.
Perspective and Isometric Views
A perspective view communicates overall three-dimensional appearance, while an isometric view uses a consistent axonometric presentation of the object. These views can orient the reader, but they may not reveal every relevant surface or internal relationship.
Exploded and Sectional Views
An exploded view separates components to explain their relationship or assembly. A section reveals a cut through the subject to clarify otherwise hidden structure. In a design application, select views to disclose ornamental appearance; do not add purely functional interior detail without considering its relevance to the design disclosure.
How Many Patent Drawing Views Are Needed?
Use enough views to explain the invention or fully disclose the claimed design. There is no universal seven-view minimum for every design application. The USPTO design guide explains view selection and appropriate omissions; the utility guide provides the relevant standards for utility figures.
Create a View Register Before Drafting
List each proposed figure, its purpose, source file and corresponding description. For a device, an overall view may orient the reader, a section may clarify an internal connection and an exploded view may explain assembly. Include each because it resolves a disclosure question. Check consistent labels, feature positions, numbering and revision versions across the final set.
