A design patent grants protection for the non-functional ornamental aspects of an article. In simpler terms, it protects the way an object looks, rather than how it works. Unlike a utility patent that protects the functionality of an invention, a design patent safeguards the visual design of an object. This can include the product's shape, configuration, surface ornamentation, or a combination of these elements.

Familiar examples include the design of a new water bottle shape, the unique pattern on a pair of sneakers, or the ornamental features of a chair. Here is a breakdown of design patents, how to prepare for one with different views, and the key requirements:

The specific views required for the design patent will depend on the complexity of your design. However, some common views include:

• The specific views required for the design patent will depend on the complexity of your design. However, some common views include:
• Perspective View: An optional view that shows the design in three dimensions, helpful for providing a general impression.
• Orthographic Views: These are flat, two-dimensional views that showcase the design from different angles.
• Front View: The primary view, typically the most aesthetically pleasing or functionally important aspect of the design.
• Back View: Shows the opposite side of the design from the front view.
• Top View: Shows the design from directly above.
• Bottom View: Shows the design from directly below.
• Side Views: One or two views from the sides, depending on the complexity of the design.

Below is an example of Tricycle invention with different views – Top, Front, Perspective and Side views.

Below are some of the typical illustration requirements of patent offices.

Professional Quality: Drawings should be clear, clean, and professional in appearance. Consider using a professional illustrator or drafting service for complex designs.

Black and White: Drawings must be submitted in black and white, with any shading used to depict surface texture or contour, not for depth.

Specific Views: The number and type of views required will depend on the patent office examiner's assessment of what is necessary to adequately disclose the design. Be prepared to provide additional views if requested.

Scale: Drawings should be submitted to a scale that allows for a clear depiction of the design details. The USPTO and other patent offices specify acceptable scales in its guidelines.

Consistency: Each view provided should be consistent with other views. For example, if a fastener is shown in the centre in one view, the same fastener should be shown exactly in the centre in all views.

No Unnecessary Elements: Avoid including unnecessary elements like background scenery, people, or stands in your drawings. Focus solely on the design itself. Avoid environmental elements. If at all you need to show an environmental item, use dotted or broken line.

These are some additional tips that can help in preparing design patent illustrations.

Dimensioning: Including dimensions is generally not required for design patents, as they focus on appearance, not functionality. However, you might consider including them if they are crucial to understanding the ornamental aspects of your design.

Broken Lines: Broken lines can be used to depict portions of the design that are not claimed as part of the invention, such as internal components hidden from view.

Material and Color Disclaimer: A note can be added to the drawings stating that the invention is not limited to specific materials or colors shown.

Further, patent drawings should satisfy / comply with the drawing standards as defined by the Patent office and it will vary for each jurisdiction. For example,

• The drawing should be submitted in A4 size
• The margins for a US application should be Top = 2.5 cm, Left = 2.5 cm, Right = 1.5 cm, Bottom = 1 cm
• The margins for an EP or PCT application should be Top = 2.5 cm, Left = 2.5 cm, Right = 1.5 cm, Bottom = 1.5 cm
• The margins for an Indian Patent application should be Top = 4 cm, Left = 4 cm, Bottom = 3 cm, Right = 3 cm
• The page number should be given in the Top of page for US, EP, PCT whereas for India it is given on Left top corner

By following these guidelines and considering the different views, you can create effective design patent illustrations that accurately represent your invention and increase your chances of a successful patent application.
