Design patents are granted to protect the ornamental design of a functional item. They don’t cover what a product does or how it works—that’s the job of a utility patent. Instead, design patents protect the visual appearance of a product: its shape, surface details, and configuration.

If your product has a unique and eye-catching design, a design patent helps ensure that no one else can legally copy that look. This protection lasts for 15 years from the date of grant and applies across industries, from fashion to tech.
In this guide, you’ll learn what qualifies for design patent protection, how it differs from utility patents, how to apply, and why it can be a valuable asset for your brand or business.
Understanding the Purpose of Design Patents
The goal of a design patent is to protect the visual character of a product. This includes the shape, surface ornamentation, and overall appearance—but not the internal structure or function.
Think about the curved bottle of Coca-Cola, the minimalist design of an iPhone, or the futuristic contours of a Tesla dashboard. These are all examples of ornamental features that have commercial value.
In today’s markets, a product’s appearance often influences buying decisions just as much as its features. Design patents give creators a way to secure exclusive rights over their visual innovations and maintain a competitive edge.
Industries where design patents play a big role:
- Consumer electronics (smartphones, earbuds)
- Home goods (furniture, appliances)
- Fashion (footwear, accessories)
- Automotive (headlights, dashboards)
- Software/UI (icons, user interfaces)
What Can Be Protected by a Design Patent?
Design patents apply to the visual elements of a manufactured item. To qualify, a design must be:
- New (not publicly available before the application)
- Original (created by or legally assigned to the applicant)
- Ornamental (not purely functional)
What this means is, the design has to be something that contributes to the aesthetic appeal of the item. You can’t patent something that’s dictated only by its function—like the shape of a wrench that’s shaped that way only to work properly.
Design patents can cover:
- The unique silhouette of a chair
- A decorative pattern on fabric
- A specific arrangement of icons on a screen
- The shape of a bottle, cap, or lamp
However, they do not cover:
- Functional aspects
- Invisible internal components
- Color alone (unless part of a GUI)
- Construction materials or manufacturing techniques
Real-World Examples of Design Patents
Some well-known companies rely heavily on design patents:
- Apple protects the rounded corners and layout of its devices. Its design patents played a major role in legal battles with Samsung.
- Crocs uses design patents to protect its distinctive clog shape and has taken legal action against copycat products.
- Dyson patents the futuristic designs of its vacuum cleaners and fans—not just how they work but how they look.
These examples show how design patents can defend market share and reinforce brand recognition.
Requirements for Design Patent Approval
To be granted a design patent, your application must meet three essential criteria:
- It must be new: The design must not have been disclosed, sold, or published anywhere in the world before your filing.
- It must be original: You must be the actual creator or have acquired the rights from the original designer.
- It must be ornamental: The design must be purely decorative and not essential to the item’s function.
The patent must also show the design as applied to a tangible product. It’s not enough to have an abstract sketch. The design must be visually presented as part of a manufactured article.
Clear, high-quality drawings or renderings are crucial. These illustrations show all sides of the design and define the scope of the protection. If your drawings are vague, incomplete, or inconsistent, your application could be delayed or rejected.
Novelty and Visual Distinction
For a design patent to be approved, it must give a different visual impression from anything already known or disclosed. Even if the differences are small, what matters is whether an “ordinary observer” would find your design visually distinct from existing designs.
The USPTO examines existing patents and public references (like catalogs, websites, or exhibitions) to determine whether your design meets this standard.
The design doesn’t need to be complex—it just needs to be unique and noticeable in its appearance. For example, adding a subtle but original pattern to a phone case might be enough to qualify.
How Design Patents Differ From Utility Patents
While both are types of intellectual property, design and utility patents serve very different purposes.

utility vs design patent |
Design patents protect how something looks. Utility patents protect how something works.
Here’s how they compare in key areas:
- Subject Matter: Design patents apply to the visual appearance; utility patents apply to new functions, systems, or processes.
- Application Contents: Design patent applications focus on drawings; utility patents require detailed technical descriptions and claims.
- Duration: Design patents last 15 years from grant; utility patents last 20 years from filing.
- Cost and Complexity: Design patents are generally faster, cheaper, and simpler to file.
Some products may qualify for both. For instance, a smartwatch could have a utility patent for its fitness tracking system and a design patent for its display interface.
Benefits of Getting a Design Patent
Design patents can be a strategic business asset, offering several advantages:
- Exclusive rights to the visual appearance of your product
- Legal grounds to stop copycats and seek damages
- Stronger branding, since consumers often associate products with specific looks
- Marketing value—you can promote your product as “patent-protected”
- Investment appeal, since patent portfolios can boost company valuation
Design patents are often the first line of defense for startups and product designers entering saturated markets. They prevent others from making products that look “confusingly similar,” even if they work differently.
How to Apply for a Design Patent
Here’s the step-by-step process:
- Create accurate drawings: These should show all angles of the product (top, bottom, front, back, sides, and perspective view). Use solid lines for claimed design features and broken lines for elements not being claimed.
- Write a brief specification: This should explain what the item is, and identify each figure in the drawing.
- File with the USPTO: Submit online using the USPTO eFiling system. Include all required documents and pay the filing fee.
- Respond to any office actions: If the examiner requests changes or raises objections, you’ll need to reply within the stated deadlines.
- Receive the patent grant: Once approved, your patent is published and protection begins immediately.
Professional help—especially for drawings—is highly recommended. Most design patent rejections stem from errors in illustrations.
Case Studies: Design Patent in Action
Apple vs. Samsung
In a high-profile lawsuit, Apple won over $500 million in damages against Samsung for infringing on iPhone design patents. The case proved that appearance alone could carry significant legal and financial weight.
Crocs Footwear
Crocs has sued multiple companies for copying the look of its foam clogs. Thanks to its design patents, Crocs was able to halt imports of knockoff designs and maintain its market dominance.
These cases show that design patents are enforceable and can have real-world impact, even in industries flooded with imitators.
Frequently Asked Questions
Can I patent a logo or brand name with a design patent?
No. Logos and brand names fall under trademark law, not design patents. Design patents are for the shape and appearance of physical items.
Can software interfaces be protected?
Yes. If you have a unique screen layout, button arrangement, or icon set, these can be protected under design patents—provided the design is new and properly illustrated.
What if my design changes slightly during production?
If the final product’s appearance differs from the patent drawings, your protection might not apply. Always match your design patent drawings to what you’ll actually produce.
Can I get international protection?
Yes. Through the Hague Agreement, you can apply for design protection in multiple countries with a single filing. But you must still comply with each country’s requirements.
Conclusion
Design patents are a cost-effective, high-impact tool to protect your product’s unique look. They don’t cover how it works, but if appearance drives your sales, they’re essential.
From sleek gadgets to stylish shoes, the right design can define your brand. A design patent ensures that look is yours alone, giving you the right to stop others from copying your work.
If you’re investing time into product design, don’t let it go unprotected. A design patent offers long-term security, brand value, and peace of mind.
