What Is a Design Patent?
A design patent protects how something looks. Unlike a utility patent, which covers how something works, a design patent is all about appearance—shape, surface decoration, layout, or ornamental design.
Key Features of a Design Patent
- Protects the visual appearance of a product
- Does not protect function or internal mechanics
- Lasts 15 years from the date of grant (in the U.S.)
- Only one claim—the drawing itself
Examples of Design Patents
- The shape of a bottle (like the Coca-Cola bottle)
- Unique smartphone interfaces or app icons
- Furniture and consumer product designs
- Jewelry, clothing accessories, and packaging
What Design Patents Don't Protect
- Methods, systems, or mechanical processes
- Anything that is functional or dictated by utility
- Abstract ideas or software code
Why File a Design Patent?
- Adds protection against copycats
- Often quicker and less expensive than a utility patent
- Valuable in industries like fashion, consumer electronics, packaging, and automotive
