Perry v. H.J. Heinz Company Brands, L.L.C.: When Packaging Similarity Is Not Trademark Infringement

Introduction: The Limits of Trade Dress and Trademark Protection

Trademark law protects consumers from confusion and businesses from unfair competition, but it does not grant companies a monopoly over general product aesthetics. The Fifth Circuit’s decision in Perry v. H.J. Heinz Company Brands, L.L.C., 994 F.3d 466 (5th Cir. 2021), provides a modern and practical illustration of this principle. The case underscores the high evidentiary burden required to prove trade dress infringement and serves as an important reminder that similarity alone is not enough to establish trademark liability.

Background of the Dispute

The dispute arose from competing condiment packaging. The plaintiff, Perry, marketed a brand of mustard and asserted trade dress rights in the overall appearance of his product’s packaging. Heinz, a dominant player in the condiment market, introduced packaging that Perry alleged was confusingly similar to his own. Perry claimed that Heinz’s packaging infringed his trade dress and misled consumers into believing the products were associated or originated from the same source.

The case presented a familiar but difficult question in trademark law: when does similarity in packaging cross the line from lawful competition into actionable infringement?

Trade Dress Law Framework

Trade dress refers to the total image and overall appearance of a product, including features such as size, shape, color combinations, graphics, and packaging design. To prevail on a trade dress infringement claim, a plaintiff must establish that the trade dress is distinctive, non-functional, and that the defendant’s use creates a likelihood of consumer confusion.

Unlike word marks or logos, trade dress claims face heightened scrutiny because granting protection over product appearance risks limiting legitimate competition. Courts therefore require plaintiffs to clearly articulate the specific elements of the claimed trade dress and to demonstrate that those elements function as a source identifier in the minds of consumers.

The Fifth Circuit’s Analysis

The Fifth Circuit affirmed summary judgment in favor of Heinz, emphasizing several critical deficiencies in Perry’s claims. First, the court found that Perry failed to precisely define the elements of his alleged trade dress. Rather than identifying a coherent combination of distinctive features, Perry relied on general similarities common to condiment packaging. Such broad descriptions, the court explained, are insufficient to support a protectable trade dress claim.

Second, the court underscored the importance of distinctiveness. Perry offered little evidence that consumers associated the claimed packaging features specifically with his brand. Without proof that the trade dress had acquired secondary meaning, the claimed design could not function as a trademark.

Third, the court rejected the notion that Heinz’s use of similar packaging elements created a likelihood of confusion. The presence of prominent branding, labeling, and source-identifying marks on Heinz’s products weighed heavily against confusion. Trademark law, the court reiterated, does not exist to protect competitors from marketplace competition, particularly where consumers are capable of distinguishing products based on clear brand identifiers.

Functionality and Competitive Necessity

Although not the sole basis for the decision, the court’s reasoning reflected ongoing concern about functionality in trade dress cases. Packaging features that are common, useful, or competitively necessary are not protectable under trademark law. Allowing one seller to monopolize standard packaging features would improperly hinder competition and conflict with the fundamental purpose of trademark protection.

Why Perry v. Heinz Matters

The decision in Perry v. Heinz carries significant implications for brand owners, especially those asserting trade dress rights. It reinforces that courts will closely scrutinize trade dress claims to ensure they are not being used to obtain de facto patent-like protection over product design or packaging concepts. Plaintiffs must do more than point to similarity; they must prove distinctiveness, non-functionality, and a real likelihood of consumer confusion.

For defendants, the case highlights the importance of strong branding and clear source identification. Prominent trademarks, logos, and labeling can significantly reduce the risk of confusion, even in crowded product categories where packaging conventions overlap.

Practical Lessons for Businesses

Businesses seeking to protect product packaging should invest early in developing distinctive, non-functional design elements and should gather evidence demonstrating that consumers associate those elements with a single source. Relying on common industry design choices will rarely support enforceable trade dress rights.

Conversely, companies launching competing products should take comfort in the fact that trademark law allows room for competition. Similarity driven by market norms or functional considerations does not automatically give rise to liability, particularly where branding is clear and transparent.

Analysis

Perry v. H.J. Heinz Company Brands, L.L.C. illustrates the modern judiciary’s cautious approach to trade dress claims. Trademark law protects source identification, not market exclusivity over common packaging designs. By reaffirming these principles, the Fifth Circuit ensured that trademark protection remains aligned with its core purpose: preventing consumer confusion without stifling legitimate competition.
