When a company develops a new product, one of the first patent questions is often whether to pursue a design patent, a utility patent, or both.
The answer depends largely on what makes the product valuable. Is the competitive advantage tied to the way the product looks? Does it come from the way the product functions? Or are both the appearance and the functionality worth protecting?
At Jafari Law Group, our patent lawyers help inventors, entrepreneurs, and businesses evaluate patent protection based on the product itself, the competitive market, and the features that may be easiest for competitors to copy.
Design Patent vs. Utility Patent: What Is the Difference?
The simplest distinction is this:
A utility patent generally protects how an invention works or is used.
A design patent protects the ornamental appearance of an article of manufacture.
The U.S. Patent and Trademark Office describes utility patents as covering new or improved and useful processes, machines, articles of manufacture, compositions of matter, and qualifying improvements. Design patents cover new, original, and ornamental designs for articles of manufacture.
Consider a newly developed kitchen appliance.
If the inventor creates a new internal mechanism that causes the appliance to operate differently from existing products, that functional feature may be suitable for utility patent protection.
If the inventor also creates a distinctive exterior shape or surface design, that appearance may be suitable for design patent protection.
Those rights protect different aspects of the same product.
What Is a Design Patent?
A design patent protects the visual, ornamental features of an article of manufacture.
That may include the product’s shape, configuration, surface ornamentation, or a combination of those elements. The USPTO emphasizes that a design patent protects a design as embodied in or applied to an article, rather than an abstract design standing alone.
Examples may include the distinctive appearance of:
- A bottle or container
- A piece of furniture
- A consumer electronic device
- A lighting fixture
- A shoe or accessory
- A product component
- Certain graphical interfaces or icons when the legal requirements are met
The protected feature must be ornamental rather than dictated solely by function.
That distinction matters. If a product has a particular shape only because that shape is required for the product to work, design patent protection may be more difficult to obtain for that feature.
What Does a Utility Patent Protect?
A utility patent is generally directed toward functionality.
It may protect a new machine, process, manufactured article, composition of matter, or an improvement to one of those categories. The invention must also satisfy patentability requirements such as novelty and nonobviousness.
A utility patent might cover:
- A new mechanical system
- A manufacturing process
- A software-related invention that satisfies patent eligibility requirements
- A chemical composition
- A new configuration of interacting product components
- A functional improvement to an existing device
The claims in a utility patent define the legal boundaries of the invention.
This can make utility patents powerful because a competitor may infringe even if its product looks entirely different, depending on whether it falls within the scope of the patent claims.
Can You Get Both a Design Patent and a Utility Patent?
Yes.
The USPTO expressly recognizes that both a utility patent application and a design patent application may be filed for the same product when the invention includes both functional and ornamental features.
This can be useful for products where competitors might copy either the underlying technology or the outward appearance.
Imagine a company develops a new wearable fitness device. The company creates a new sensor arrangement that improves how the device measures movement. It also develops a distinctive housing that gives the product a recognizable appearance.
The sensor system could potentially be addressed through a utility patent application, while the appearance of the housing could potentially be addressed through one or more design patent applications.
The two forms of protection serve different purposes.
When a Design Patent May Make Sense
A design patent may be particularly useful when appearance plays a major part in why customers recognize or choose a product.
This can happen in industries such as consumer electronics, furniture, apparel accessories, household products, packaging, tools, automotive components, and medical devices.
Design patents can also be useful when competitors could reproduce the product’s appearance without copying the internal technology.
Suppose a company sells a desk lamp with fairly conventional electrical components but an unusual and recognizable housing. The functional components may offer limited opportunities for utility patent protection, but the ornamental configuration of the lamp could present a separate design patent issue.
The analysis depends on the design and existing prior art.
When a Utility Patent May Make More Sense
A utility patent may be the stronger focus when the product’s commercial advantage comes primarily from what it does.
A product may look ordinary while incorporating a highly valuable technical improvement.
Consider a pump that externally resembles other pumps in the market but contains a new internal arrangement that reduces energy consumption. The appearance may not be commercially significant. The functional improvement may be the part worth protecting.
Utility patents can also cover broader concepts than a particular product appearance when properly drafted and supported.
That broader potential scope is one reason utility patent applications are often more involved to prepare and prosecute.
How Long Does Each Type of Patent Last?
For current U.S. applications, design patents generally have a term of 15 years from the date the patent is granted.
Utility patents generally have a term of up to 20 years from the earliest applicable nonprovisional filing date, subject to patent-term rules and possible adjustments. Utility patents also require maintenance fees after issuance to remain in force.
Design patents do not require the same periodic USPTO maintenance fees after issuance.
The different term structures can affect filing strategy, especially for products with long commercial life cycles.
How to Get a Design Patent
The process begins by identifying exactly what visual features should be protected.
A U.S. design patent application typically includes drawings or photographs showing the claimed design, a specification, and a single claim. The visual disclosure is particularly important because the drawings largely define the scope of what is being claimed.
A typical process involves several steps:
- Evaluate the design. Determine which features are ornamental and whether certain portions should be claimed or left unclaimed.
- Review prior designs. Existing patents, published applications, products, and other public disclosures can affect patentability.
- Prepare the drawings. Drawings should consistently show the claimed design from the required views. Small differences in line treatment can affect the scope of the patent.
- Prepare and file the application. The application is filed with the USPTO along with the required government fees.
- Respond to USPTO examination. A patent examiner reviews the application and may issue objections or rejections that require a response.
- Pay the issue fee if allowed. Once the USPTO allows the application, the required issue fee must be paid before the patent grants.
The USPTO does not allow applicants to add new subject matter after filing. That makes careful preparation at the beginning particularly important.
Why Design Patent Drawings Matter So Much
In a utility patent, written claims define the boundaries of protection.
In a design patent, the drawings effectively carry much of that burden.
Solid lines generally identify claimed portions of a design, while broken lines can be used in appropriate circumstances to show environmental or unclaimed subject matter. How those drawings are prepared can substantially affect what the patent ultimately covers.
Suppose two versions of a product share the same distinctive front panel but use different rear housings.
Depending on the filing strategy, it may be possible to focus the claimed design on the front-panel features rather than limiting the patent to every visible feature of one exact product configuration.
These decisions should be made before filing because new matter generally cannot later be added to the application.
How Much Does a Design Patent Cost?
The total design patent cost usually includes two separate categories: USPTO government fees and the cost of preparing and prosecuting the application.
As of September 2026, the USPTO lists the basic design patent filing fee at $300 for a large entity, $120 for a qualifying small entity, and $60 for a qualifying micro entity. The USPTO also requires separate design search and examination fees.
Current design patent fees include:
| USPTO Fee | Large Entity | Small Entity | Micro Entity |
| Basic filing fee | $300 | $120 | $60 |
| Search fee | $300 | $120 | $60 |
| Examination fee | $700 | $280 | $140 |
| Issue fee, if allowed | $1,300 | $520 | $260 |
Those figures are government fees only and can change. They also do not include patent attorney fees, professional patent drawings, responses to Office Actions, petitions, international filings, or other costs that may arise.
Small-entity and micro-entity discounts are available only when the applicant satisfies the applicable USPTO requirements.
For that reason, there is no single design patent cost that applies to every product.
Are Design Patents Cheaper Than Utility Patents?
Often, yes, but not always.
Design patent applications tend to contain less written technical material than utility patent applications. That can make them less costly to prepare in many cases.
A utility patent application may require a detailed technical description, multiple claims of varying scope, inventor interviews, analysis of alternative embodiments, and a more involved examination process.
The difference can become significant when a product has several inventions or several visual configurations that warrant separate applications.
Cost should not be the only deciding factor. A less expensive form of patent protection is not necessarily useful if it protects the wrong part of the product.
What Happens If Someone Makes a Product That Looks Similar?
Design patent infringement focuses on the patented design rather than simply asking whether two products share individual elements.
Under the governing legal framework, courts consider the overall visual impression from the perspective of an ordinary observer familiar with the relevant prior art.
This is another reason the scope of the design shown in the patent drawings matters.
A very narrowly claimed design may leave competitors more room to change individual visual features. A filing strategy that appropriately focuses on commercially significant design elements may provide different coverage.
Whether infringement exists is a fact-specific legal question and should not be determined from a side-by-side visual comparison alone.
What Happens If Someone Copies How Your Product Works?
That is generally where utility patent claims become more relevant.
Utility patent infringement depends on whether the accused product or process contains each limitation of an asserted patent claim, either literally or, in some circumstances, under the doctrine of equivalents.
A competitor does not necessarily avoid a utility patent simply by changing the exterior appearance.
Similarly, owning a design patent does not automatically give the owner rights over every product that performs the same function.
Each type of patent protects a different legal interest.
Should You File Before Showing the Product to the Public?
Early filing is often the safer approach.
Public disclosures, sales, offers for sale, trade shows, crowdfunding campaigns, websites, social media posts, investor presentations without adequate confidentiality protections, and other disclosures can affect patent rights.
U.S. law provides certain inventor-related grace-period rules, but relying on them can create problems, particularly when international rights are important. Many foreign jurisdictions are less forgiving of pre-filing disclosure.
A business planning a product launch should therefore consider patent strategy before the public rollout rather than after it.
What If the Product Is Still Changing?
Products often evolve between prototype and commercial launch.
That can affect both design and utility patent strategy.
If the functional concept is established but the exterior appearance is still changing, utility protection may need to be considered before the final industrial design is complete.
If several exterior designs are being tested, a business may need to evaluate which versions deserve design patent filings and when.
Because new subject matter cannot simply be added to an already-filed application, substantial changes sometimes require additional filings.
Design Patents Are Not the Same as Trademarks
Product owners sometimes assume that a design patent protects a brand name or logo in the same way a trademark does.
These are different forms of intellectual property.
A patent grants rights relating to an invention or design for a limited statutory term. A trademark identifies the source of goods or services and can potentially remain enforceable as long as the mark continues to function as a source identifier and the applicable legal requirements are met.
Some product features may potentially implicate both design patent and trade dress protection, but the legal standards are different.
A broader intellectual property strategy may therefore involve patents, trademarks, copyrights, trade secrets, or a combination of those rights.
Choosing Between a Design Patent and a Utility Patent
The right question is often not simply, “Which patent is better?”
A more useful question is, “What part of this product would hurt the business most if a competitor copied it?”
If the answer is the product’s visual appearance, design patent protection may deserve serious consideration.
If the answer is the underlying technology, operation, or method, utility patent protection may be more appropriate.
If competitors could gain an advantage by copying either one, pursuing both may be worth evaluating.
Patent strategy should also account for the product’s expected commercial life, development budget, launch timing, prior art, likely competitors, planned product variations, and international markets.
