What is a design patent?

A design patent is a type of patent granted by the United States Patent and Trademark Office (USPTO) that protects the ornamental or aesthetic appearance of a functional item. Unlike utility patents, which protect how an invention works, a design patent protects how it looks.

What Does a Design Patent Protect?

A design patent covers the visual characteristics of a product, including:

• Shape and configuration (eg, the unique contour of a bottle).
• Surface ornamentation (eg, patterns or decorative elements on a product).
• Combination of shape and ornamentation (eg, the overall visual appearance of a consumer product).
  
  

Examples of Design Patents:

• The iconic shape of a Coca-Cola bottle.
• The rounded corners of a smartphone.
• The user interface icons or graphical designs of software.
  
  

Key Requirements for a Design Patent

To qualify for a design patent, the design must be:

1. Novel (35 USC § 171)
   • The design must be new and original, not previously disclosed or publicly available.
2. Non-functional
   • The design must be purely ornamental. If it serves a functional purpose, it may be more suitable for a utility patent.
3. Non-obvious
   • The design must not be an obvious variation of existing designs to someone skilled in the art.

Design Patent Application Process

1. Filing the Application
   • Includes:
     • Drawings or photos showing multiple views of the design (typically front, back, side, top, bottom, and perspective views).
     • A description of the design.
     • One or more claims defining the design's visual characteristics.
2. USPTO Examination
   • The examiner reviews the application to ensure the design is novel and ornamental.
   • The process is generally faster and simpler than for utility patents.
3. Approval and Grant
   • If approved, the applicant pays issue fee, and the design patent is granted.
   • Design patents last for 15 years from the date of grant and do not require maintenance fees.
     
     

Design Patent vs. Utility Patent

Key Takeaway

A design patent protects the visual appearance of a product rather than its functionality. It lasts for 15 years and offers a cost-effective way to safeguard distinctive and recognizable product designs.
