Gray Market Goods Infringement: Why Genuine Products Can Still Trigger U.S. Trademark Liability

In today’s world, where cross-border e-commerce and global distribution are increasingly common, one of the misunderstandings brand owners most often encounter is the idea that “as long as the goods are genuine, there can be no infringement.” U.S. federal courts do not take that view. For U.S. trademark law, the issue is often not whether the goods originated from the factory, but whether what U.S. consumers receive is still the “U.S.-market version” of the branded product as they understand it. The Supreme Court recognized early on in A. Bourjois & Co. v. Katzel that even if the defendant sold genuine goods manufactured by the original French factory, the conduct could still constitute infringement if it harmed the goodwill accumulated by the U.S. trademark owner in the U.S. market. Prestonettes v. Coty, however, reminds us that resale of genuine goods is not automatically unlawful. The key remains whether the conduct is likely to mislead the public. In other words, U.S. law does not simply take either side of “genuine goods are innocent” or “parallel imports necessarily infringe.” Instead, the analysis centers on consumer confusion and the protection of goodwill.
The Infringement Boundary for Parallel Imports and Gray Market Goods in U.S. Federal Litigation
This point is especially prominent in today’s cases involving gray market goods. In practice, what plaintiffs usually allege is not that “the defendant is selling counterfeit goods,” but rather that “although the goods sold by the defendant are genuine, they are not the version sold through authorized U.S. channels and therefore are no longer genuine goods in the trademark-law sense.” Once a court accepts this characterization, the case shifts from ordinary secondhand resale or circulation of genuine goods into a trademark infringement and unfair competition case under the Lanham Act.
Gray Market Goods Under U.S. Law Are Not the Same as “Parallel Imports” in Everyday Usage
Both parallel imports and gray market goods refer to genuine goods circulated through unofficial channels, but “parallel imports” is a broad colloquial term used more in commercial and regulatory contexts, while “gray market goods” is a strict legal concept in U.S. law centered on trademark rights and consumer confusion. Under U.S. law, especially in the context of U.S. Customs and Border Protection (“CBP”) and federal courts, these concepts require more precise definitions. What the Supreme Court discussed in K Mart Corp. v. Cartier, Inc. was gray market goods in the customs-law sense, namely goods manufactured abroad, bearing a lawful U.S. trademark, but imported without the consent of the U.S. trademark owner. The focus of that case was the scope of customs law and Section 526 of the Tariff Act, not the complete establishment of a civil infringement standard. For that reason, after K Mart, what truly supported federal civil litigation was mainly the “material differences” theory gradually developed by the various circuit courts.
Therefore, at the litigation level, a brand owner cannot simply say, “These are parallel imports” or “These are gray market goods.” It must further demonstrate whether there are differences between those imported goods and the U.S.-authorized version sufficient to affect U.S. consumers’ purchasing decisions. Without this step, the case is often difficult to establish. With this step, even if the goods are genuine, they may still be deemed by a court to be “non-genuine goods” in the trademark-law sense.
How Federal Courts Determine Whether Parallel Imports and Gray Market Goods Infringe
The core test applied by U.S. federal courts in these cases is already very clear: whether there are material differences between the accused goods and the U.S.-authorized version. This standard does not require the differences to be enormous, nor does it require the plaintiff to prove that a large amount of actual consumer confusion has already occurred. In Societe Des Produits Nestle v. Casa Helvetia, the First Circuit clearly stated that under the Lanham Act, a plaintiff only needs to prove a likelihood of confusion and does not need to prove that actual confusion has already occurred. The court also stated that in gray market goods cases, injunctive relief is often supported even without evidence of actual confusion.
This also explains why the material differences theory is so powerful in gray market goods cases. Once a difference is found to be “material,” courts usually further infer that, when consumers encounter the same trademark, they will naturally understand the goods to have the same quality, packaging, service, warranty, and brand endorsement as goods sold through U.S.-authorized channels. That understanding is precisely what the defendant’s sales conduct distorts.
What Exactly Counts as a “Material Difference”?
Many companies initially assume that only differences in formula, materials, components, or performance count as material differences. U.S. case law is not that narrow. In Original Appalachian Artworks v. Granada Electronics, the Second Circuit addressed the entry of Spanish-version Cabbage Patch Kids dolls into the U.S. market. The court supported the plaintiff, in part because the adoption papers and birth certificates accompanying the dolls were in Spanish. That difference was sufficient to cause a deviation in the experience and expectations of consumers in the U.S. market. The importance of this case is that it shows that “accompanying documents, language, and performance experience” themselves may also constitute material differences.
The First Circuit in Nestle v. Casa Helvetia pushed the application of material differences even further. That case involved different versions of PERUGINA chocolates. The court held that differences in packaging, varieties, ingredients, price, quality control, and transportation and storage methods could all be relevant “differences.” In other words, as long as a difference could be important to U.S. consumers when making a purchase, there is a chance that the court will include it in the assessment of “materiality.”
What is even more important for brand owners to note is that a difference does not necessarily have to be a “physical difference.” The Federal Circuit clearly stated in SKF USA Inc. v. ITC that nonphysical differences may also constitute material differences. Services, warranties, and accompanying documents may all create differences between gray market goods and authorized goods sufficient to support a trademark infringement finding. The Tenth Circuit continued this reasoning in Beltronics USA v. Midwest Inventory Distribution: when goods lose certain upgrades, discounts, warranties, and service support because of differences in the handling of serial numbers, those differences may be included in the trademark infringement analysis. For brands that emphasize after-sales systems, warranty coverage, missing-part replacement, recall support, and membership benefits in the U.S. market, this line of cases has significant practical importance.
Quality Control Is Not Just a Slogan
In gray market goods litigation, brand owners also often argue that “these goods did not go through our U.S. quality control.” This route is available, but courts will not automatically accept it merely because the plaintiff says the words “quality control.” The Third Circuit in Iberia Foods Corp. v. Romeo clearly warned that the quality control asserted by the plaintiff must be real, specific, and substantively meaningful. If the so-called inspection merely excludes obviously damaged or plainly unsellable goods, and those problems were unlikely to reach consumers in the first place, then this practice of “screening out obviously defective goods” is insufficient to create a material difference that can support an infringement conclusion.
This is a very important practical reminder for brand owners. A truly effective quality-control argument cannot remain at an abstract level. It should be grounded as much as possible in verifiable systems and implementation facts. For example: whether the goods must go through a specific testing process before entering U.S. channels; whether they must match U.S.-version packaging and compliance labels; whether they must be entered into the U.S. after-sales database; and whether they must be tied to U.S.-version warranties, recalls, serial numbers, and customer service systems. Only when these systems are made concrete will courts be more likely to accept the argument that “goods not released through this system are no longer genuine goods.”
Why the Lever Line of Cases Is So Important
If K Mart was primarily a customs-law case, then the Lever Brothers line of cases almost laid the modern framework for protection based on “physical or material differences.” In Lever Brothers Co. v. United States, the D.C. Circuit faced the issue of differences between U.K.-version and U.S.-version cleaning products. The court stated that the purpose of the Lanham Act is clearly to protect the goodwill of U.S. trademark owners in the U.S. market and that foreign-version goods should not be allowed to free ride on goodwill in the U.S. market. The subsequent Lever Brothers Co. v. United States again reaffirmed that even if goods are genuine in overseas markets, they may still infringe U.S.-registered trademark rights.
The importance of these two cases lies not only in supporting brand owners’ reliance on material differences in federal court, but also in their later direct influence on the CBP administrative protection pathway known as the Lever-rule. Today, whenever one discusses “CBP border protection measures against gray market goods with material differences,” the intellectual origin almost inevitably traces back to these two cases.
What Claims Do Brand Owners Most Commonly Assert in Federal Court?
In terms of claim design, the most common core claims in these cases remain registered trademark infringement and federal unfair competition under the Lanham Act. The reason is that once goods are found to be non-genuine because of material differences, the brand owner can argue that the defendant’s sale of those goods using the same trademark is likely to cause confusion about source, sponsorship, approval, or product characteristics. In other words, the focus of the case is no longer “whether the trademark is real,” but rather “whether the same trademark conceals important differences between the goods and the U.S.-authorized version.” This is also why complaints in gray market goods cases often include packaging differences, language differences, manual differences, after-sales differences, warranty differences, recall eligibility, and service-support differences together.
Are TROs and Preliminary Injunctions Easy to Obtain in These Cases?
However, it should also be recognized that whether these cases can successfully obtain a TRO or preliminary injunction often depends not on the statutory text itself, but on whether the plaintiff can explain the differences with sufficient specificity. The more easily the court can intuitively understand differences such as packaging-language differences, differences in after-sales coverage, warranty and recall support differences, accompanying-document differences, and differences in product traceability and quality-control mechanisms, the more likely a preliminary injunction will be issued. Conversely, if the plaintiff has only vague statements such as “we did not authorize this” or “our brand will be harmed,” without structured evidence, the court may find the materials insufficient.
Can the Defendant Defeat the Plaintiff’s Claims by Adding a Disclaimer?
This is another issue often misjudged in gray market goods cases. If the defendant states on the product page that “this product is not authorized for sale by the U.S. trademark owner,” that may indeed weaken the plaintiff’s argument concerning confusion over an authorized relationship to some extent, but it usually will not automatically destroy the plaintiff’s case. The reason is that the core of a gray market infringement claim is not merely that “consumers mistakenly think this is sold by an authorized dealer.” More importantly, it is whether “consumers mistakenly think they are buying the same branded product as the U.S.-authorized version.” If the disclaimer does not clearly explain the material differences and does not truly make consumers aware that the goods differ in packaging, instructions, warranty, after-sales service, missing-part replacement, recall support, and other respects, then it does more to reduce risk than to eliminate risk. What the Supreme Court accepted in Prestonettes was labeling that truthfully explained the relationship and was sufficient to prevent deception, not an abstract self-exculpatory statement.
Is Statutory Damages Available?*
On this issue, many brand owners easily confuse gray market goods cases with counterfeit cases. The conclusion is very clear: if the essence of the case is “genuine parallel imports plus material differences,” rather than a counterfeit or fake-goods infringement case, then the plaintiff usually cannot directly seek statutory damages under the Lanham Act provisions specifically directed at counterfeit marks. The special arrangements for enhanced monetary remedies and statutory damages under 15 U.S.C. § 1117 are built around counterfeit marks, not ordinary gray market goods cases.
This means that monetary remedies in gray market goods cases are usually closer to those in traditional trademark infringement and unfair competition cases. The plaintiff’s main focus is the defendant’s profits, the plaintiff’s actual damages, litigation costs, and, in appropriate circumstances, attorney’s fees. In other words, if the case is not about counterfeiting but rather “genuine goods with material differences,” then brand owners should not treat statutory damages as the default weapon. More realistic expectations usually include injunctive relief, disgorgement of profits, and compensation for actual losses.
Note: Statutory damages refer to damages for which the law predetermines a range when actual losses are difficult to prove, and the court then determines the amount within that range at its discretion.
If There Is No Statutory Damages, How Are Monetary Remedies Calculated?
In these cases, monetary remedies usually revolve around two main lines. One is the plaintiff’s own actual damages, including losses caused by disruption to the pricing system, diversion of authorized-channel sales, and harm to brand positioning and goodwill. The other is the defendant’s unjust enrichment, namely the profits the defendant obtained by selling gray market goods with material differences. For brand owners, the latter often becomes the focus of litigation because the plaintiff’s actual damages are often difficult to quantify precisely, while once the defendant’s sales are identified, the disgorgement-of-profits route is usually more operationally practical.
But this also leads to a practical judgment: in genuine gray market goods cases, injunctive relief is often more strategically valuable than damages. This is not because damages are unavailable, but because the real harm gray market goods cause brand owners often lies in the disruption of channel order, pricing systems, after-sales systems, and brand expectations. These consequences are inherently more difficult to fully express in a single number than in counterfeit-goods cases. Therefore, in many cases, the first goal is not to obtain high damages, but to quickly suppress the sales conduct and then continue investigating profits and supply chains during discovery.
The Relationship Among CBP, the Lever-Rule, and Federal Litigation
When considering whether to sue, many brand owners ask: since CBP already faces enforcement pressure in the small-package cross-border e-commerce context, would federal court injunctions encounter the same practical obstacles? This judgment is not without reason. Whether it is Lever-rule border protection or a federal court injunction, when facing gray market goods problems characterized by “direct-mail small packages, scattered sellers, low per-shipment value, and fragmented logistics chains,” neither mechanism can achieve comprehensive interception in the same way as traditional container inspections. From this perspective, the two do share some practical enforcement difficulties.
But if one therefore concludes that “federal litigation and CBP have about the same value,” that underestimates the true advantages of federal litigation in cross-border e-commerce. CBP and the Lever-rule focus mainly on the border, and the core issue is “whether this shipment can be identified and stopped upon entry.” Federal litigation is different. Its advantage lies not only in “stopping goods,” but also in directly attacking the entire commercial infrastructure that supports the infringing business. Once the plaintiff obtains a TRO, preliminary injunction, or other court order, it can often further push e-commerce platforms to remove product links, close or restrict stores, freeze store funds, restrict continued listings, cut off payment tools, and even take measures against related domain names, independent websites, PayPal accounts, and other payment channels. Compared with relying solely on border identification, this path is closer to directly cutting off the sales chain, funding chain, and traffic entry points. Its impact is often more direct and more likely to force defendants to stop operating.
This is precisely the point most worth emphasizing when comparing federal litigation with the CBP mechanism. CBP’s strength lies in border administrative enforcement. It solves the question of “whether the goods can enter.” Federal litigation’s strength lies in using court orders to act on platforms, payment service providers, domain registrars, warehousing nodes, and other third-party facilitators, thereby addressing “how the goods are sold, how the money is collected, and how the store continues operating.” For gray market goods cases involving AliExpress, independent websites, and other cross-border e-commerce scenarios, the latter is often closer to the source of the problem. Even if it is impossible to intercept every shipment, as long as stores, payments, and traffic entry points can be continuously suppressed, the defendant’s infringing business model itself will be significantly weakened.
Therefore, in today’s cross-border e-commerce environment, brand owners should not understand CBP and federal litigation as simple substitutes for each other. The Lever-rule is more like a border-pressure tool that increases uncertainty and risk for goods entering the United States. Federal litigation, by contrast, is a more penetrating market-governance tool that can apply pressure from the sales end, funding end, and operational end at the same time. The former mainly targets “goods”; the latter targets not only “goods,” but also “people, stores, money, and channels.” For this reason, when handling gray market goods and parallel import issues, federal litigation is usually more likely than reliance on CBP alone to change the conditions that allow the infringing business to continue operating at the source.
What Companies Really Need to Prepare Before Filing Suit
If a company intends to bring gray market goods, parallel import, or unauthorized-channel genuine-goods issues into U.S. federal court, the most important thing is not to first decide which platform or seller to sue. Instead, it must first answer a more fundamental question: can you turn the differences between the “U.S. version” and the “non-U.S. version” into an evidence system that the court can understand, verify, and directly connect to consumer confusion? This system should usually include packaging comparisons, manual comparisons, compliance-label comparisons, warranty and after-sales policy comparisons, missing-part replacement and recall eligibility comparisons, product serial-number and quality-control mechanism comparisons, as well as consumer reviews, customer-service records, and test-purchase evidence. Only when these materials are in place can a parallel import case truly be transformed from a commercial complaint into an actionable federal trademark case.
Conclusion
The attitude of U.S. federal courts toward gray market goods, parallel imports, and unauthorized-channel genuine goods has never been that “as long as the goods are genuine, there is definitely no problem.” The real issue is whether these goods have material differences from the U.S.-authorized version sufficient to affect consumer decision-making, and whether those differences cause the same trademark to conceal important gaps between different market versions. Katzel laid the foundation for the protection of U.S. goodwill; K Mart provided the contours of gray market goods in the customs-law context; and Original Appalachian, Nestle, Iberia, Lever, Beltronics, and SKF together shaped today’s material differences rule. For brand owners, the most important message conveyed by these cases is not that “parallel imports always infringe,” but that “as long as the differences are sufficiently important, genuine goods may also lose their genuine status under U.S. trademark law.”
