Rule of Law:
A product design feature is functional, and thus not protectable as trade dress, if it is essential to the use or purpose of the product or affects its cost or quality. The availability of alternative designs is irrelevant when a feature is functional under this primary test.
Facts:
- Eppendorf-Netheler-Hinz GMBH (Eppendorf) is a German company that manufactures a popular line of disposable pipette tips known as 'Combitips' for use with its dispenser syringes in laboratories.
- The Combitips have a specific design configuration, which includes features like a top flange, support fins, a plunger head, and specific lengths and coloring.
- Eppendorf dominated the American market for these disposable pipette tips.
- In the early 1990s, Ritter GMBH (Ritter), another German manufacturer, began producing disposable pipette tips, called 'Ritips,' that were virtually identical in design to Eppendorf's Combitips.
- Ritter, through its U.S. distributor RK Manufacturing, Inc., entered the American market in 1994.
- Ritter's Ritips were designed to be compatible with Eppendorf's dispenser syringes and were marketed as a 'direct replacement' for Combitips.
- Ritter priced its Ritips below Eppendorf's Combitips in an effort to capture market share.
Procedural Posture:
- Eppendorf filed suit against Ritter and RK Manufacturing in the U.S. District Court for the Eastern District of New York, alleging trade dress infringement under the Lanham Act.
- The case was transferred to the U.S. District Court for the Southern District of Mississippi.
- A jury trial was held, resulting in a verdict for Eppendorf, finding that Ritter and RK had willfully infringed on Eppendorf's trade dress rights.
- The jury awarded Eppendorf $750,000 in lost profits and $250,000 in lost licensing fees.
- The district court entered a final judgment for Eppendorf, adding $750,000 in enhanced damages and issuing a permanent injunction against Ritter and RK.
- Ritter and RK (Defendants-Appellants) appealed the district court's judgment to the U.S. Court of Appeals for the Fifth Circuit.
- Eppendorf (Plaintiff-Appellee) filed a cross-appeal regarding the denial of attorneys' fees and prejudgment interest.

Issue:
Are product design features that are essential to the use or purpose of the product, or that affect its cost or quality, considered functional and thus ineligible for trade dress protection, even if alternative designs are available?
Opinions:
Majority - Judge Edith H. Jones
Yes, product design features that are essential to the product's function are ineligible for trade dress protection, regardless of whether alternative designs exist. The Lanham Act requires the party asserting trade dress protection to prove that the feature is non-functional. Following the Supreme Court's decision in TrafFix Devices, Inc. v. Marketing Displays, Inc., the primary test for functionality is the 'traditional' definition: 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. This court's prior 'utilitarian' test, which focused on competitive necessity and the availability of alternatives, is now a secondary inquiry. Here, Eppendorf's entire case for non-functionality rested on demonstrating that alternative designs were available for the eight features in question. However, the evidence showed that each of the eight features—the flange, fins, plunger, coloring, etc.—was essential to the Combitips' operation, such as by providing structural support, enabling connection to the syringe, or facilitating measurement. Because these features are 'the reason the device works,' they are functional as a matter of law. The existence of other design possibilities is irrelevant under the primary functionality test.
Analysis:
This decision solidifies the application of the Supreme Court's TrafFix functionality standard in the Fifth Circuit, prioritizing the 'traditional' functionality test over the previously used 'competitive necessity' or 'utilitarian' test. It significantly narrows the scope of trade dress protection for product design by making it clear that features essential to a product's use or purpose cannot be protected, even if competitors could have designed their products differently. The ruling reinforces the boundary between patent law, which protects useful inventions for a limited time, and trademark law, which protects source-identifying marks and features indefinitely, thereby preventing companies from using trade dress to achieve perpetual patent-like monopolies on functional designs.
