Design patents protect one of the most commercially underestimated forms of intellectual property: how a product looks. While utility patents dominate most conversations about patents, design patents have been at the center of some of the most significant IP disputes in history — including Apple's decade-long litigation against Samsung that resulted in over $1 billion in damages.
For inventors and product designers, understanding what design patents cover, what they cost, and when they make strategic sense is essential to building a complete IP strategy.
What Is a Design Patent?
A design patent protects the novel, ornamental appearance of an article of manufacture — the way a product looks, not the way it works. Under 35 U.S.C. § 171, a design patent may be granted for any new, original, and ornamental design for an article of manufacture.
The key distinction from a utility patent: a utility patent protects function (what an invention does and how it does it), while a design patent protects form (the visual appearance of the object).
A design patent cannot protect an aesthetic feature that is dictated purely by the function of the object — if a shape exists only because the item must work that way, it is considered functional and cannot be protected by design patent.
What a Design Patent Covers
Design patent protection extends to the ornamental appearance of an article, which can include:
- The overall shape or configuration of a product
- Surface ornamentation (patterns, textures, graphic elements applied to a surface)
- A combination of shape and surface ornamentation
- The appearance of a portion of a product (using broken lines to disclaim the unclaimed portions)
- User interface elements and screen displays (under updated USPTO guidelines)
- Typefaces and fonts
- Icons, logos, and graphical user interface elements as applied to an article
What a design patent does NOT cover: functionality, methods of use, internal structure, or any feature that is purely the result of how the article works.
The "Article of Manufacture" Requirement
A design patent must be tied to an article of manufacture — the design must exist as applied to a physical product or a screen display. A standalone two-dimensional design (like an illustration that is not applied to any product) generally cannot be design-patented; it would be protected instead by copyright.
The article requirement is one of the most common sources of rejection in design patent applications: applicants must clearly show what the article is and what portions of it are being claimed.
Design Patent vs. Utility Patent: Key Differences
Many inventions are eligible for both design patent and utility patent protection simultaneously. Understanding the differences helps inventors decide which type to pursue — or whether to pursue both.
| Feature | Design Patent | Utility Patent |
|---|---|---|
| What it protects | Ornamental appearance of a product | How an invention works or is used |
| Duration | 15 years from date of grant | 20 years from filing date |
| Maintenance fees | None required | Due at 3.5, 7.5, and 11.5 years |
| Number of claims | Exactly one claim (the design itself) | Multiple independent and dependent claims |
| Application cost | Lower — typically $1,500–$3,500 all-in | Higher — typically $5,000–$15,000+ all-in |
| Prosecution timeline | ~18–24 months average | ~2–3 years average |
| Scope of protection | Narrower — look and feel of the design | Broader — functional concept, multiple embodiments |
| Description requirement | Minimal text — the drawings are the claim | Detailed written specification required |
| Can protect same product? | Yes — both can apply to a single product if it has novel appearance AND novel function | |
A product like a uniquely shaped water bottle might warrant a utility patent (if the shape serves a novel functional purpose) and a design patent (for the ornamental appearance) simultaneously. Filing both provides layered protection that is harder for competitors to design around.
How Long Does a Design Patent Last?
A design patent issued from an application filed on or after May 13, 2015, lasts 15 years from the date of grant. Design patents filed before that date lasted 14 years.
Unlike utility patents, design patents require no maintenance fees — once granted, the patent remains in force for its full term with no renewal payments. The 15-year term runs from the grant date, not the filing date.
Design Patent Requirements: What Qualifies
To qualify for a design patent under USPTO examination standards, the design must satisfy three requirements:
1. Novelty (35 U.S.C. § 102)
The design must not have been previously patented, described in a printed publication, or in public use or on sale more than one year before the filing date. The U.S. offers a one-year grace period from public disclosure — but international filings under the Hague Agreement do not; in most foreign jurisdictions, any public disclosure before the filing date destroys novelty.
Be advised: international design patents under the Hague System must be filed within six months of the original US application.
2. Non-Obviousness (35 U.S.C. § 103)
The design must not have been an obvious variation of existing designs to an "ordinary designer" skilled in the relevant field. Minor changes in proportions, color choices alone, or simple rearrangement of known design elements typically fail this test.
Examiners compare the claimed design to the prior art corpus using the "ordinary observer" test from Egyptian Goddess, Inc. v. Swisa, Inc. (Fed. Cir. 2008).
3. Ornamentality
The design must be ornamental — not purely functional. A design that is entirely dictated by the functional requirements of the article cannot be design-patented. If the shape of a part is required for it to connect to another part or function properly, that shape is functional and not protectable.
However, if there are multiple possible shapes that would serve the same function equally well, a choice among them for aesthetic reasons can still qualify as ornamental.
The Design Patent Application: What It Contains
Unlike utility patent applications — which are primarily text-driven with detailed written descriptions and multiple claims — a design patent application is primarily visual. The drawings are the claim; the written specification is brief by comparison.
Required Components
Drawings (the most critical element): Design patent drawings must show the claimed design from every angle necessary to fully disclose the appearance. USPTO rules typically require views from the front, rear, left side, right side, top, and bottom — six standard views — plus any perspective views needed to convey the three-dimensional character of the design.
Every line in the drawings is legally significant. Solid lines indicate claimed portions; broken (dashed) lines indicate portions of the article that are not being claimed and are shown for environmental context only.
Specification: A design patent specification is short by patent standards. It includes a preamble identifying the title of the design and the article it applies to, a cross-reference to related applications if any, a brief description of each drawing view, and the single claim: "The ornamental design for [article], as shown and described."
The claim: A design patent has exactly one claim. The scope of that claim is defined entirely by the drawings. This is why professional-quality drawings prepared in conformance with USPTO rules (37 C.F.R. § 1.84) are not optional — they are the patent.
Common Drawing Mistakes That Cause Rejections
- Inconsistent line weights across views — solid lines that should be dashed, or vice versa
- Missing a required view (often the bottom view is omitted)
- Surface shading that is unclear or inconsistent between views
- Photographs submitted instead of professional line drawings (photographs are accepted only in limited circumstances)
- Broken lines used inconsistently — sometimes claiming features, sometimes disclaiming them across views
- Title that doesn't match the article shown (e.g., "container" when the drawings show a bottle)
Drawing errors are the most common reason design patent applications receive office actions. Professional drawings by a patent draftsperson working under attorney supervision typically cost $200–$600 depending on complexity but can save weeks of prosecution time and prevent scope narrowing.
Design Patent Costs and Timeline
USPTO Filing Fees (as of 2025)
| Fee | Micro Entity | Small Entity | Large Entity |
|---|---|---|---|
| Basic filing fee | $60 | $120 | $300 |
| Search fee | $60 | $120 | $300 |
| Examination fee | $140 | $280 | $700 |
| Total USPTO fees | ~$260 | ~$520 | ~$1,300 |
Most individual inventors and small businesses qualify for micro entity or small entity status, which significantly reduces USPTO fees. Qualifying as a micro entity requires meeting gross income limits and not having been named on more than four previously filed patent applications.
Attorney Fees
At Michael Meyer Law, design patent attorney fees are approximately $1,500–$2,000 for a straightforward single-embodiment design, including preparation and filing. This is substantially lower than utility patent attorney fees ($4,000+) because design patent applications require minimal written description and a single claim — the primary work is coordinating professional drawings and ensuring the drawings comply with USPTO requirements.
All-In Cost Estimate
Most individual inventors file as small or micro entities, making the total cost for a professionally prepared design patent application approximately $1,800–$3,000 all-in. This compares favorably with the $5,000+ cost of a utility application and reflects the simpler structure of design patent prosecution. See our complete patent cost guide for a full breakdown of fees and timeline.
Timeline
Design patent applications currently average 18–24 months from filing to grant at the USPTO, with first office actions typically arriving 12–18 months after filing. Design patent pendency is generally shorter than utility patent pendency, which averages 2–3 years for most technology areas.
There is no provisional equivalent for design patents — design patent applications go directly to non-provisional status. However, a utility patent provisional can sometimes be used to establish a priority date for a design that is part of a product with both functional and ornamental features, as long as the design is disclosed in the provisional's drawings.
The "Ordinary Observer" Test: How Design Patent Infringement Works
Design patent infringement is evaluated using the "ordinary observer" test established in Egyptian Goddess, Inc. v. Swisa, Inc. (Fed. Cir. 2008): a design patent is infringed if an ordinary observer, familiar with the prior art, would be deceived into thinking the accused design is the same as the patented design.
Because design patents protect visual appearance, proving infringement requires comparing the overall visual impression of the accused product against the patented design — not comparing functional features or claim elements individually.
Apple v. Samsung: The High-Stakes Consequences
The Apple v. Samsung litigation, initiated in 2011, remains the most prominent design patent case in history. Apple asserted design patents covering the rectangular front face, rounded corners, and bezel of the iPhone, as well as the icon grid of the iOS home screen.
The case eventually reached the Supreme Court in 2016 (Samsung Electronics Co. v. Apple Inc.), which addressed how damages should be calculated when a design patent covers only a component of a complex product — not the entire article. The Supreme Court held that an "article of manufacture" for damages purposes could be a component of a product rather than the entire product, sending the damages calculation back to the lower courts.
The case ultimately settled, but not before demonstrating that design patents can generate billion-dollar damages claims and that the ornamental appearance of consumer electronics is worth serious IP protection.
For product companies, design patents are not a secondary consideration — they are often the fastest and most cost-effective first line of protection while utility patent prosecution proceeds.
When Does a Design Patent Make Strategic Sense?
Design patents are particularly valuable in specific situations:
- Consumer products where appearance drives purchasing decisions. Products like furniture, housewares, consumer electronics accessories, apparel, packaging, and sporting goods derive significant commercial value from their aesthetic differentiation. A design patent prevents competitors from releasing visually similar products while the original is still in its commercial prime.
- Fashion and apparel. While clothing cannot generally be protected by copyright in the U.S. (because fashion is considered functional), distinctive ornamental elements — shoe soles, buckle designs, surface patterns applied to an article — can qualify for design patent protection. This is a significant area of design patent activity in footwear and luxury goods.
- Graphical user interfaces and screen displays. Following a 2020 update to USPTO design patent guidelines, animated GUI elements and transitional screen displays are now eligible for design patent protection. Technology companies routinely file design patents on icon designs, layout configurations, and interactive display elements.
- Complementing a utility patent application during prosecution. A utility patent application can take 2–3 years. A design patent on the same product can grant in 18–24 months, giving the inventor enforceable IP rights against copycat designs while the more powerful utility patent works its way through examination.
- International design protection via the Hague Agreement. The U.S. joined the Hague System in 2015, allowing a single international design application to pursue protection in over 90 member jurisdictions. For inventors with global commercial ambitions for a distinctive-looking product, the Hague Agreement streamlines international design protection substantially.
Design Patent vs. Copyright: Can You Have Both?
Yes — a design can be simultaneously protected by both a design patent and copyright, and understanding the overlap is practically important.
Copyright protects original creative expression automatically from the moment it is created. For a two-dimensional artistic work applied to a product — a fabric print, a decorative illustration on a mug — copyright protection arises without registration. However, copyright protects only the specific creative expression, not the design as applied to a particular article of manufacture in the same way a design patent does.
A design patent provides broader protection against similar-looking products even when the similarity doesn't rise to the level of copyright infringement. Under the ordinary observer test, a design patent can prevent a competitor from releasing a product that looks substantially similar to the patented design — even if the competitor made the design independently without copying. Copyright requires copying; a design patent does not.
For ornamental surface designs, logos, and distinctive packaging, filing both a design patent application and a copyright registration provides layered, overlapping protection with different standards and remedies.
Frequently Asked Questions
Can I file a design patent after my product is already on the market?
Yes, but the clock is running. The U.S. grants a one-year grace period from the first public disclosure — once you've publicly sold, offered for sale, or described the design, you have one year to file. After that year, the right to a U.S. design patent is lost. International design patent protection is even less forgiving: most foreign jurisdictions require filing before any public disclosure.
Do design patents require maintenance fees?
No. Design patents issued in the U.S. require no maintenance fees for their full 15-year term. This is a meaningful advantage over utility patents, which require maintenance fees at 3.5, 7.5, and 11.5 years after grant.
How is a design patent different from a trademark?
A design patent protects the ornamental appearance of an article for a fixed term (15 years). A trademark — including trade dress — protects source-identifying features that distinguish a company's goods in commerce, potentially indefinitely. The shape of a product can qualify for trade dress protection under the Lanham Act if it is distinctive and non-functional. Some product appearances are protected by both a design patent (during the patent term) and trade dress (potentially indefinitely if the shape becomes a recognized source identifier). Apple's iPhone design is an example where both apply.
Can a design patent protect software or app interfaces?
Yes. The USPTO accepts design patent applications for graphical user interfaces, screen displays, and icons as applied to a computer screen, phone, or other display article. The application must identify the article (e.g., "display screen with graphical user interface") and include drawings showing the claimed GUI elements. Animated elements are also protectable under 2020 USPTO guidelines updates, provided the drawings adequately show the transition.
What happens when a design patent is infringed?
A design patent holder can pursue remedies including a preliminary injunction to stop sales of the infringing product, actual damages (lost profits or reasonable royalties), the infringer's total profits attributable to the infringing design under 35 U.S.C. § 289 (the provision at issue in Apple v. Samsung), and attorney fees in exceptional cases. The § 289 total profits remedy — which can require disgorgement of all profits from the sale of an article incorporating the infringing design — is what made Apple's design patent claims so economically significant. Contact a patent attorney promptly if you suspect infringement; delay can affect available remedies.
Should I file a design patent or a utility patent for my product?
If your product has both a novel appearance and a novel function, consider filing both. If the primary commercial value is in the appearance (packaging, consumer goods, furniture, fashion accessories), a design patent is typically the right first move — it's faster and significantly cheaper. If the primary value is in the function (a new mechanism, a new process, a novel composition), a utility patent is the priority. When in doubt, a consultation with a patent attorney will help clarify which type of protection provides the most defensible coverage for your specific product.
How do I get started with a design patent application?
The first step is confirming your design hasn't been previously patented or published — a USPTO design patent search through Patent Center. Michael Meyer Law offers a $500 prior art search, which includes a review of issued design patents and published applications before recommending whether to proceed with a design patent application, a utility application, or both. See the complete patent cost guide for a full breakdown of fees and timeline.
