Trade Dress Infringement Lawsuits
Demandas por infracción de imagen comercial: empaques, diseños de producto y decoración de locales.
When a competitor copies the look of your packaging, your product, or your store, Section 43(a) of the Lanham Act lets you sue even without a registration. To win, you must define the trade dress precisely, prove that buyers see it as your brand, prove it is not functional, and show that the copy is likely to confuse. We bring these cases for brand owners in Florida, Latin America, and Europe, often with design patent and copyright claims alongside.

Trade dress is the look that tells buyers who made the product
Trade dress is the overall appearance of a product or its packaging, when that appearance identifies the source. The Eleventh Circuit describes it as the "total image of a product," which may include size, shape, color, texture, graphics, and even sales techniques (Dippin' Dots, Inc. v. Frosty Bites Distribution, LLC, 369 F.3d 1197 (11th Cir. 2004)). Think of a bottle shape, a box design, the layout and décor of a restaurant chain, or the shape of a product itself.
Most trade dress is not registered, and the claim to enforce it is Section 43(a) of the Lanham Act, 15 U.S.C. § 1125(a), which reaches any "word, term, name, symbol, or device" used in commerce in a way likely to cause confusion. If the trade dress is registered on the Principal Register, you can also sue under 15 U.S.C. § 1114, with the presumptions that come with registration. See Federal Trademark Infringement Litigation.
Trade dress cases are harder than word-mark cases. The plaintiff has to define something visual in words, prove that buyers see it as a brand rather than as decoration or a useful feature, and, for unregistered trade dress, prove it is not functional. Many cases are won or lost on those threshold issues before confusion is ever weighed. If you have not yet protected your trade dress, start with Trade Dress Registration or Florida Trade Dress Registration.
Three kinds of trade dress, three rules
- Packaging: labels, containers, boxes, bottle wraps. Can be inherently distinctive.
- Product design: the shape or configuration of the product itself. Never inherently distinctive; secondary meaning is required.
- Restaurant and retail décor: treated like packaging in Two Pesos; the Supreme Court later called it something close to packaging, a "tertium quid."
- Ambiguous cases are treated as product design (Wal-Mart v. Samara, 2000).
Define the trade dress precisely, in a list of elements
Every later issue depends on the definition: what is distinctive, what is functional, and what the defendant copied. A vague description ("the look and feel of our products") invites a motion to dismiss and a jury that cannot tell what it is protecting.
The standard is not uniform. The Second Circuit requires the plaintiff to "separate out and clearly identify in a list the discrete components that make up its trade dress" (Cardinal Motors, Inc. v. H&H Sports Protection USA, Inc., 2d Cir. Feb. 6, 2025). We have not found an Eleventh Circuit decision setting the same rule. Florida federal courts have been more forgiving at the pleading stage while still expecting specifics. In Ducharme Seating International v. Series USA (S.D. Fla. 2024), Chief Judge Altonaga accepted a complaint that identified specific design features and attached photographs, while repeating an earlier warning that a plaintiff "may be well advised to identify the distinctive elements of its design more specifically." Middle District courts have said a plaintiff must at least identify the aspects it claims are non-functional, and that "trade dress claims require specificity."
We draft to the stricter standard anyway. The definition will be tested again on summary judgment, in the jury instructions, and in the wording of any injunction, and a definition broad enough to cover a style or an idea will fail. The Eleventh Circuit compares the overall impression of the products, so the list should describe a combination, not isolated features.
How we write the definition
- List each element: shape, proportions, color placement, materials, graphics, layout
- Describe the combination as a whole, with photographs or drawings
- Leave out features that serve a purpose or appear across the industry
- Use the same definition in the complaint, expert reports, and proposed injunction
- Avoid "such as," "including," "typically," or other open-ended words
- Match what you actually sold and advertised, consistently, over time
Three elements, each a possible stopping point
The Eleventh Circuit requires a Section 43(a) trade dress plaintiff to prove that (1) the trade dress of the two products is confusingly similar, (2) the features are primarily non-functional, and (3) the trade dress is inherently distinctive or has acquired secondary meaning (Dippin' Dots, 2004). Because all three are required, a court may decide the case on any one of them.
| Element | What you must show | How it is usually proved | Typical evidence |
|---|---|---|---|
| A defined trade dress you use in U.S. commerce | A specific, consistent combination of elements that you own and use | The written definition, with photographs and sales history | Product samples, packaging files, catalog and ad archives, launch dates |
| Distinctiveness | Inherent distinctiveness (packaging, décor) or secondary meaning (always for product design) | Market evidence under the Eleventh Circuit's four factors; consumer surveys | Advertising that features the look, sales, unsolicited media, "look-for" campaigns, secondary-meaning surveys |
| Non-functionality | The features are not essential to use or purpose, do not affect cost or quality, and are not needed to compete | Plaintiff's burden for unregistered trade dress (§ 1125(a)(3)); engineering and design testimony; alternative designs | Patent history, design files, cost data, competitors' alternative designs |
| Likelihood of confusion | The defendant's trade dress is likely to confuse buyers about source, sponsorship, or affiliation | The seven Eleventh Circuit factors, comparing overall impression | Side-by-side photos, channels, intent evidence, actual confusion, surveys |
Packaging can be inherently distinctive; product design never is
Two Supreme Court decisions set the framework. In Two Pesos, Inc. v. Taco Cabana, Inc. (1992), the Court held that inherently distinctive trade dress, there a restaurant's décor, is protected under Section 43(a) without proof of secondary meaning. In Wal-Mart Stores, Inc. v. Samara Brothers, Inc. (2000), it held that product design is protectable "only upon a showing of secondary meaning," because "design, like color, is not inherently distinctive."
The shape of a chair, a shoe, or a boat hull is product design. A bottle label, a box, or a hang tag is packaging. A store or restaurant interior is treated like packaging.
Courts are told to "err on the side of caution and classify ambiguous trade dress as product design" (Wal-Mart). If there is a real argument either way, plan to prove secondary meaning.
Ask whether the overall combination is arbitrary or suggestive in its market, rather than common or merely descriptive. In AmBrit, Inc. v. Kraft, Inc., 812 F.2d 1531 (11th Cir. 1986), the Eleventh Circuit protected the Klondike ice cream bar wrapper as a whole (its square size, bright coloring, pebbled texture, and polar bear and sunburst images) even though individual elements were common. Some courts outside this circuit apply the Seabrook test (is the design a common basic shape, unique or unusual in its field, or a mere refinement of a commonly adopted form?). We have not found Eleventh Circuit precedent adopting it, so we brief the issue under the circuit's own cases and address Seabrook-style arguments if the defendant raises them.
Then the case turns on market evidence, described in the next section. Without it, a product design claim fails no matter how close the copy.
Four factors the Eleventh Circuit uses to find secondary meaning
Secondary meaning exists when the buying public associates the look with a single source. The Eleventh Circuit weighs four factors from Conagra, Inc. v. Singleton, 743 F.2d 1508 (11th Cir. 1984). A survey is usually the most direct evidence on the last one.
Length and manner of use
How long and how consistently you have used the same look. Frequent redesigns weaken the claim.
Sales history, product archiveNature and extent of advertising
Not just spending, but whether ads feature the trade dress itself. Spend on the brand name alone proves little about the shape.
Ad samples, media plansEfforts to link the look to you
"Look for" advertising, packaging shots, social posts that call out the design, and consistent presentation in stores and online.
Campaign files, social contentWhether the public actually identifies it with you
Secondary-meaning surveys, unsolicited media, retailer and customer testimony, and evidence that copyists targeted the look.
Survey, declarationsFor brands launched in Latin America or Europe, recognition abroad does not substitute for recognition by U.S. buyers; we look for U.S. sales, U.S. advertising, and U.S. distributor and retailer testimony.
For unregistered trade dress, you must prove it is not functional
Section 43(a)(3) puts the burden on "the person who asserts trade dress protection" to prove "that the matter sought to be protected is not functional." In the Eleventh Circuit, features "are deemed functional until proved otherwise by the party seeking trade dress protection" (Dippin' Dots).
Utilitarian functionality
The traditional test
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" (TrafFix Devices, Inc. v. Marketing Displays, Inc., 2001, applying Inwood). If a feature is functional under that test, the inquiry ends; the court need not consider whether competitors have alternative designs. A utility patent claiming the feature is "strong evidence" of functionality, and the plaintiff then carries a "heavy burden" to show otherwise.
Aesthetic functionality
Competitive necessity
A feature that is not useful in the engineering sense can still be functional if exclusive use would put competitors at a "significant non-reputation-related disadvantage." The Supreme Court discussed this test in Qualitex (1995) and TrafFix. In Dippin' Dots, the Eleventh Circuit held the color, size, and shape of the ice cream functional under the traditional test (color signals flavor; size and shape follow from the freezing process), and noted that they would also be functional under the competitive-necessity test.
What helps a plaintiff
Building the non-functionality record
Evidence that the feature was chosen for appearance, not performance; that it costs the same or more to make; that competitors sell successful products without it; that your advertising does not tout its utility; and that no utility patent claims it.
What the defendant will use
Expect these exhibits
Your own patents (expired ones included), marketing that praises how the feature works, engineering files, industry standards, and testimony that buyers want the feature for reasons unrelated to source. A patent's silence on a feature does not prove it is non-functional (Dippin' Dots).

Registered and unregistered trade dress compared
Registering trade dress is harder than registering a word mark, but a registration changes the litigation in the plaintiff's favor.
| Issue | Registered (Principal Register) | Unregistered |
|---|---|---|
| Federal claim | § 1114 and § 1125(a) | § 1125(a) only |
| Validity and ownership | Certificate is prima facie evidence (§§ 1057(b), 1115(a)); conclusive once incontestable (§ 1115(b)) | Plaintiff proves both from scratch |
| Burden on functionality | Registration is presumed valid, so the challenger must prove functionality | Plaintiff must prove non-functionality (§ 1125(a)(3)) |
| Functionality as a defense | Still available, even against an incontestable registration (§ 1115(b)(8)); cancellation "at any time" (§ 1064(3)) | Available |
| Distinctiveness | Established in examination; product design is usually registered on proof of acquired distinctiveness under § 1052(f) | Plaintiff proves inherent distinctiveness or secondary meaning |
| Priority | Nationwide constructive use from filing date (§ 1057(c)) | Limited to actual use and reputation |
| Likelihood of confusion | Plaintiff must prove | Plaintiff must prove |

The same seven factors, applied to overall appearance
Trade dress confusion is judged by the same seven Eleventh Circuit factors used for word marks: strength of the trade dress, similarity of design, similarity of the products, retail outlets and purchasers, advertising media, the defendant's intent, and actual confusion. See the factor-by-factor guide on our Federal Trademark Infringement Litigation page.
Two points matter more in trade dress cases. First, the comparison is of overall impression, so the defendant will stress differences in its labels, logos, and house marks. Clear labeling can dispel confusion, and in Dippin' Dots the Eleventh Circuit found no likely confusion between the parties' logos even though six of the seven factors favored the plaintiff, because the logos looked so different. Second, intent evidence often carries weight. In AmBrit, the court noted that a competitor's effort to come as close as the law allows to a successful trade dress can be strong evidence of likely confusion.
Post-sale confusion is often central for product designs, since buyers see the product after the label is gone. The Eleventh Circuit has recognized that likely confusion includes post-sale confusion of the purchasing public (United States v. Torkington, 1987).
Evidence we gather on confusion
- Side-by-side photographs as buyers see the products, on shelf and online
- Marketplace search results showing the products together
- Product returns, warranty claims, and reviews naming the wrong brand
- Evidence of copying: timing, prior dealings, shared suppliers or molds
- A likelihood-of-confusion survey, designed for trade dress stimuli
Remedies, and the design patent and copyright claims that travel with trade dress
A trade dress plaintiff gets the Lanham Act remedies: an injunction with the rebuttable presumption of irreparable harm (§ 1116(a)), the defendant's profits, actual damages, costs, and fees in exceptional cases (§ 1117(a)), and destruction of infringing materials (§ 1118). For valuation, see Damages Evaluations. Where the copied product is also covered by a design patent or copyright, adding those claims can make the case easier to win.
| Claim | What it protects | Proof advantage | Limits |
|---|---|---|---|
| Trade dress (§ 1125(a) / § 1114) | Source-identifying look, for as long as it is used and distinctive | No fixed term; covers packaging, design, and décor | Secondary meaning for product design; functionality; confusion |
| Design patent | Ornamental design of an article of manufacture | No need to prove secondary meaning or confusion; infringer liable for its "total profit," at least $250 (35 U.S.C. § 289) | Only if a design patent issued; term of 15 years from grant (35 U.S.C. § 173) |
| Copyright | Artistic features of packaging, labels, graphics, and features of a useful article that can be imagined separately as art | Protects copied artwork without proof that buyers link it to you | Useful-article features protected only if separable (Star Athletica v. Varsity Brands, 2017) |
| Florida claims | Common-law unfair competition and FDUTPA | Added remedies and a state-law route | See Florida common law and FDUTPA |

Five common mistakes in trade dress cases
These are the threshold problems that end trade dress claims before confusion is reached. Accused parties should see Defending Trade Dress Infringement Claims.
Claiming a style instead of a trade dress
A definition that covers a general look or a design category reads as an attempt to own an idea, and courts reject it.
DefinitionList specific elements and show them in images.
Treating product design as packaging
Pleading inherent distinctiveness for a product shape fails as a matter of law, and close cases are treated as design.
Wal-Mart v. Samara (2000)Plan to prove secondary meaning from the start.
Ignoring your own patents and ads
A utility patent, or marketing that praises how a feature works, is the defendant's best functionality evidence.
TrafFix (2001)Audit patents and marketing before defining the trade dress.
Advertising the brand, not the look
Large ad budgets that never feature the design say little about whether buyers recognize it.
Conagra factorsRun "look for" advertising long before any dispute.
Changing the design every season
Inconsistent presentation weakens both the definition and secondary meaning.
Length and manner of useKeep the core elements constant, and register them when you can.

Frequently asked questions
Do I need a registration to sue for trade dress infringement?
No. Unregistered trade dress is protected under 15 U.S.C. § 1125(a). A registration helps: it is prima facie evidence of validity and ownership, and it shifts the burden on functionality to the defendant. See Trade Dress Registration.
How specific does my description of the trade dress need to be?
Specific enough that a court and jury can tell exactly what is protected. Florida federal courts have accepted complaints that list specific features with photographs, and the Second Circuit requires a clear list of elements. We write the definition as a closed list of elements describing the overall combination.
Is my product's shape protectable without proof that consumers recognize it?
No. Under Wal-Mart v. Samara (2000), product design is protectable only with secondary meaning. Packaging and restaurant décor can be inherently distinctive, but ambiguous cases are treated as product design.
What evidence proves secondary meaning?
The Eleventh Circuit looks at the length and manner of use, the nature and extent of advertising, efforts to connect the look with your company, and whether the public actually identifies it with you. A well-designed survey is often the most direct evidence on the last factor.
What makes trade dress functional?
A feature is functional if it is essential to the product's use or purpose or affects its cost or quality, or if giving you exclusive rights would put competitors at a significant disadvantage unrelated to reputation. A utility patent covering the feature is strong evidence of functionality (TrafFix, 2001).
Who has to prove the trade dress is or is not functional?
For unregistered trade dress, the plaintiff must prove it is not functional (§ 1125(a)(3)). For registered trade dress, the registration is presumed valid, so the party challenging it carries the burden, although functionality remains a defense even against an incontestable registration.
Can I add design patent or copyright claims?
Yes, if you have them. A design patent claim does not require secondary meaning or confusion and lets you recover the infringer's total profit on the article. Copyright can protect graphics and separable artistic features. These claims are often pleaded together with trade dress.
Does a different label on the copy defeat my claim?
Not necessarily, but it matters. Courts compare overall impression, and a prominent different brand name can weigh against confusion at the point of sale. Post-sale confusion, which the Eleventh Circuit recognizes, can still support the claim for products seen after purchase.
