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:
- Novel (35 USC § 171)
- The design must be new and original, not previously disclosed or publicly available.
- Non-functional
- The design must be purely ornamental. If it serves a functional purpose, it may be more suitable for a utility patent.
- Non-obvious
- The design must not be an obvious variation of existing designs to someone skilled in the art.
Design Patent Application Process
- 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.
- Includes:
- 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.
- 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
feature | Design Patent | Utility Patent |
|---|---|---|
Protects | Ornamental appearance | Functional aspects |
Duration | 15 years from grant date | 20 years from filing date |
Examination | Simpler and faster | More complex and lengthy |
Application Cost | Lower cost | Higher cost |
Number of Claims | Usually one claim | Multiple claims covering functionality |
Examples | Shape of a phone, pattern on fabric | Internal phone components, software |
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.
