Trade dress is the overall visual identity of a product that tells consumers where it came from: the shape of a bottle, the color of a box, the layout of a store, the look of an app. Common examples of trade dress include the contour of the Coca-Cola bottle, the robin’s-egg blue of a Tiffany jewelry box, the red lacquered sole on a Christian Louboutin heel, the silhouette of the Volkswagen Beetle, the interior of a Taco Cabana restaurant, and the layout of an Apple retail store. Federal law protects these visual identifiers under 15 U.S.C. § 1125, which lets a business stop competitors from copying a look consumers have come to associate with a single source.1Office of the Law Revision Counsel. 15 USC 1125 – False Designations of Origin and False Descriptions Forbidden
Packaging Examples
Packaging is where most people first encounter trade dress. The Coca-Cola bottle is the textbook case. Its curved, fluted glass shape is recognizable in silhouette, with no label needed. The bottle doesn’t make the soda taste better or keep it fresher. It exists to signal one brand, and that combination of recognizability and non-functionality is exactly what the law protects.
The Tide detergent bottle works on the same logic. The bright orange color and bullseye graphics let a shopper spot the brand from across the aisle before reading a word. Tiffany’s jewelry box does it with a single color: the robin’s-egg blue doesn’t make the box sturdier or the jewelry inside more valuable, but decades of consistent use have taught consumers whose box it is.
Packaging qualifies for protection when it is either inherently distinctive or has acquired what courts call secondary meaning, which is proof that consumers link the look to a specific brand rather than treating it as generic decoration. In Two Pesos, Inc. v. Taco Cabana, Inc., the Supreme Court held that inherently distinctive packaging does not need proof of secondary meaning.2Justia. Two Pesos, Inc. v. Taco Cabana, Inc., 505 US 763 (1992) That gives newer brands a path to protection before they have years of sales data behind them.
Single Colors
A single color can function as trade dress on its own. In Qualitex Co. v. Jacobson Products Co., the Supreme Court held that the Lanham Act’s definition of a trademark is broad enough to include a color by itself, provided the color has acquired secondary meaning.3Justia. Qualitex Co. v. Jacobson Products Co., 514 US 159 (1995) The case involved a green-gold color used on dry cleaning press pads that had become so closely tied to one manufacturer that a competitor using the same shade was found to be trading on someone else’s reputation.
Tiffany Blue fits within this rule. So does Christian Louboutin’s red sole on high-heeled shoes, which the Second Circuit found protectable when the red sole contrasts with the upper part of the shoe. There is one firm limitation: single-color marks are never inherently distinctive. The brand owner always has to prove that consumers learned to associate the color with a particular source, which usually means showing extensive advertising, long use, and strong sales.
Color protection also has a ceiling. The color cannot be functional. If a shade is standard in an industry, no single company gets to own it. Think safety orange for construction vests.
Product Shape and Design
The physical shape of the product itself can serve as trade dress, but the legal bar is higher. In Wal-Mart Stores, Inc. v. Samara Brothers, Inc., the Supreme Court ruled that product design is never inherently distinctive and always requires proof of secondary meaning.4Justia. Wal-Mart Stores, Inc. v. Samara Brothers, Inc., 529 US 205 (2000) The reasoning: consumers generally expect a product’s design to make the item more appealing or useful, not to identify its maker. A cocktail shaker shaped like a penguin, the Court noted, is probably meant to be charming rather than to signal a brand.
That higher bar hasn’t stopped well-known shapes from earning protection. The silhouette of the Volkswagen Beetle, the body of a Gibson Les Paul guitar, and the Hermès Birkin handbag are all examples where the form itself functions as a brand identifier. None of those shapes are necessary for the product to work. A car doesn’t need that particular curve to drive, a guitar doesn’t need that cutaway to make sound, and a handbag doesn’t need that trapezoid profile to hold your things. The shapes are non-functional, and years of commercial use have taught consumers to recognize them at a glance.
Store Layout and Atmosphere
The look and feel of a place of business can also qualify. The leading case is Two Pesos v. Taco Cabana, where the Supreme Court held that a restaurant’s festive interior, including its color scheme, floor plan, and decorative elements, was protectable trade dress without proof of secondary meaning because the overall look was inherently distinctive.2Justia. Two Pesos, Inc. v. Taco Cabana, Inc., 505 US 763 (1992) The jury instructions defined trade dress as the “total image of the business,” covering everything from the exterior shape to the kitchen floor plan to the servers’ uniforms.
Apple’s retail stores are a more recent example. Apple obtained federal service mark registrations for the store layout, including the glass storefront, cantilevered wooden shelves, rectangular display tables arranged in parallel lines, and the Genius Bar at the rear below flush-mounted screens. The registration was granted based on acquired distinctiveness. Apple showed that the store layout itself had become a brand identifier.
In both cases, no single element carries the protection. It is the combination working together that qualifies. And the design still cannot be purely functional. A kitchen layout dictated by health codes, or an open floor plan chosen only because it cuts construction costs, would not make it.
Websites and App Interfaces
Courts have recognized that website and app designs can qualify for trade dress protection, though the area is still developing. The overall look of an interface, including its color palette, icon design, navigation layout, and content arrangement, can serve as a source identifier when the combination is distinctive and non-functional.
The analysis mirrors physical trade dress. Commonplace elements like a search bar at the top of a page or a hamburger menu icon are functional conventions that no one owns. But a distinctive combination of design choices can be protectable. The more unique elements a developer brings together, the stronger the potential claim.
The practical problem is that digital design evolves fast and conventions spread faster. Proving secondary meaning for an app layout that has existed for a year or two is much harder than proving it for a bottle shape that has been on shelves for decades. That is where digital trade dress claims tend to struggle.
What Cannot Be Protected: The Functionality Bar
The functionality doctrine is the single biggest limitation on trade dress, and it defeats more claims than anything else. If a design feature is essential to what the product does, or if it affects the cost or quality of making the product, it cannot be trade dress. That is true no matter how recognizable the feature has become.
The Supreme Court set out the test in TrafFix Devices, Inc. v. Marketing Displays, Inc.: a feature is functional if it is “essential to the use or purpose of the article or if it affects the cost or quality of the article.”5Justia. TrafFix Devices, Inc. v. Marketing Displays, Inc., 532 US 23 (2001) The case involved a dual-spring design for road signs that made them wind-resistant. An expired utility patent on the same design was treated as strong evidence that the feature was functional.
That last point carries real weight. If the feature you want to protect was ever claimed in a utility patent, courts treat that as powerful evidence of functionality, and overcoming the inference is a heavy lift.5Justia. TrafFix Devices, Inc. v. Marketing Displays, Inc., 532 US 23 (2001) For unregistered trade dress, the statute also puts the burden on the person claiming protection to prove non-functionality. Courts will not assume it.1Office of the Law Revision Counsel. 15 USC 1125 – False Designations of Origin and False Descriptions Forbidden
Registering Trade Dress
Trade dress can be registered with the U.S. Patent and Trademark Office. Registration brings practical advantages: a legal presumption of validity, nationwide constructive notice to competitors, and the right to use the ® symbol. The base filing fee is $350 per class of goods or services under the most recent schedule.6USPTO. Summary of 2025 Trademark Fee Changes
The application needs a clear description of the elements being claimed and usually a drawing or photograph showing the overall look. For product design, the USPTO will always require proof of acquired distinctiveness. Useful evidence includes advertising spend, sales figures, consumer studies linking the design to its source, media coverage, length of exclusive use, and evidence that competitors have tried to copy the look.
Registration is not required to enforce trade dress. Unregistered trade dress is protectable under 15 U.S.C. § 1125(a), and many of the most famous disputes have involved unregistered designs.1Office of the Law Revision Counsel. 15 USC 1125 – False Designations of Origin and False Descriptions Forbidden The tradeoff is that an unregistered claimant carries the burden of proving non-functionality, while registration shifts some of that burden to the challenger.
