On June 12, 2019, the U.S. Court of Appeals for the Seventh Circuit decided Bodum USA, Inc. v. A Top New Casting Inc., No. 18-3030, 2019 U.S. App. LEXIS 17555 (7th Cir. June 12, 2019). The case was based on an allegation of infringement by A Top of Bodum’s unregistered trade dress in its Chambord® French press coffee maker design and squarely addressed the doctrine of “functionality” of trade dress. The court addressed two important issues related to functionality: (1) what type of evidence is necessary to prove functionality of a particular design and (2) under what circumstances are utility patents relevant to that analysis? Counseled by Vedder Price, Bodum convinced the court to accept its position on these crucial questions.

In Bodum, there was no dispute that the designs were similar (as shown below with the Bodum design on the left and the A Top French press on the right):

Bodum, 2019 U.S. App. LEXIS 17555, at *2. Evidence presented at trial established that Bodum has a long history of protecting the design of its Chambord® French press and advertising its distinctive features, namely, its metal cage, metal pillars ending in curved feet, C-shaped handle and domed lid topped with a spherical knob. Id. at *3.

Trade dress, which is a variety of trademark protection, refers to a particular design or configuration (including packaging or the design of the product itself) that is so distinctive that consumers immediately recognize it as associated with a unique source. Trademark law is based on consumer protection laws. Thus, if a company markets a particular good or service (such as a French press coffee maker) in a way that confuses a consumer into believing that the good or service is that of someone else, such actions constitute unfair competition, and the action is one for trademark infringement. For any trademark infringement claim, a trademark owner needs to prove that it has a valid trademark (that is, that the mark is distinctive enough that consumers associate it with a single source), and that the accused mark is likely to cause confusion as to source. When the trademark is trade dress, there is an additional requirement to show infringement. Because trade dress applies to the configurations (e.g., shape) of a product, there is an additional requirement on the trade dress owner to prove that the trade dress is not “functional.” A trade dress is “functional” if it confers an unfair advantage in terms of cost or quality, or would exclude others from competing for the same type of product. The distinction is necessary because functional innovations (i.e., what things do and how they work) can be protected only through the grant of a utility patent. Obtaining a utility patent requires the overcoming of significant hurdles, including proving that the functional innovation is both new (nobody has done it before) and not obvious (even if new, it would not have been obvious to do). If a person could obtain trade dress protection for functional designs, that person could obtain the equivalent of utility patent protection without meeting the stringent requirements for entitlement to a utility patent.

The tension between utility patent protection and trade dress protection is exemplified by the U.S. Supreme Court’s case, TrafFix Devices, Inc. v. Mktg. Displays, Inc., 532 U.S. 23, 28–29 (2001). In that case, the Court held that there is a rebuttable presumption that features of a design patent (which is very similar to trade dress protection in that it protects ornamental, nonfunctional designs) that are claimed in a utility patent are functional. Because of the close similarity between design patent protection and trade dress protection, the Seventh Circuit extended that same presumption to trade dress protection. Georgia-Pacific Cons. Prods., LP v. Kimberly-Clark Corp., 647 F.3d 723, 727–28 (7th Cir. 2011). Those cases were important aspects of the district court litigation between Bodum and A Top.

To prove infringement in the case at hand, Bodum had to establish three elements: (1) it owned a valid trade dress in the Chambord® French press product, (2) the designs of the Chambord® French press and the A Top product were likely to cause confusion among consumers and (3) the trade dress of the Chambord® French press was not functional.

Bodum prided itself on the beautiful design of its products, including the French press coffeemaker trademarked as the Chambord ®. The Chambord ® French press was originally designed by a French designer, who took his inspiration from the tops of the towers of the Chateau Chambord, located in the Loire Valley in France. In 1991, Bodum purchased Martin SA, which owned the Chambord ® design. Since that time, Bodum alleged that it has grown the design into an icon and has been working with Vedder Price to vigorously enforce its intellectual property “trade dress.” At trial, Bodum introduced the numerous design awards the Chambord ® has received, as well as the Chambord ®’s recognition by the Museum of Modern Art and multiple design publications (such as Phaidon Design Classics and Red Dot Design Yearbook) as “classic,” “legendary” and “timeless.”

Consequently, A Top did not contest likelihood of confusion or Bodum’s ownership of the trade dress. Instead, it contested only the functionality of the design. Bodum, 2019 U.S. App. LEXIS 17555, at *6–7.

A jury returned a verdict for Bodum, awarding $2 million in damages, which the district court doubled to $4 million for willfulness. Id. at *5–6. On appeal, A Top made two arguments. It argued first that Bodum had not met its burden of proving non-functionality, and second that the district court had erred by excluding from evidence certain utility patents that would have established functionality.

The Seventh Circuit affirmed. On the burden issue, the Seventh Circuit faulted A Top for painting its functionality picture too broadly, focusing on the functionality of the elements themselves instead of the functionality of the actual designs. As the Seventh Circuit noted (with its emphasis):

Bodum does not claim that any French press coffeemaker with a handle, a domed top, or metal around the carafe infringes on its trade dress. Rather, it is the overall appearance of A Top’s SterlingPro, which has the same shaped handle, the same domed lid, the same shaped feet, the same rounded knob, and the same shaped metal frame as the Chambord, that Bodum objects to. Thus, to establish it has a valid trade dress, Bodum did not have to prove that something like a handle does not serve any function. It merely needed to prove that preventing competitors from copying the Chambord’s particular design would not significantly disadvantage them from producing a competitive and cost-efficient French press coffeemaker.

Id. at *9–10. The court went on to cite the testimony of both parties’ experts that the particular elements of the Chambord® French press were not necessary to the design, or that alternatives would work just as well (if not better). Id. at *10–12. The court also noted the testimony that the trade dress design did not confer an unfair advantage in terms of cost or quality (one way of determining whether a trade dress is functional). In fact, Bodum’s use of metal components and particularly shaped handle made the design more expensive than alternative French presses with feet, a cage, a handle and a domed lid. Id. at *13–14. In other words, Bodum’s Chambord® design did not confer an unfair competitive advantage on Bodum, since other equally functional French press designs remained available, including ones at a lower cost.

The court next addressed A Top’s argument that the district court had erred by excluding utility patents that would have shown the trade dress to be functional. At trial, Bodum’s expert was asked whether certain utility patents disclosed the elements of Bodum’s trade dress. Id. at *16–17. However, only portions of the patents were shown to the witness, consisting largely of pictures taken from those patents. Id. at *17. The witness testified that he could not tell what were disclosed as important functional elements in the patents solely from pictures. Id. What a utility patent actually protects as the functionality of the innovation is described in words at the end of the patent, called “claims,” and not in pictures. Because he understood the claims to be critical to the question of what aspects of those patents were functional, and he had been presented with pictures and not the patents’ actual claims, Bodum’s expert could not make an assessment of any functionality based on the patents A Top’s attorneys presented to him. Id.

Upon objection, the district court excluded the patents as potentially confusing to a jury under Federal Rule of Evidence 403.¹ The district court, recognizing that a utility patent can create a presumption of functionality, nevertheless limited that presumption to circumstances in which the utility patent claims the trade dress features in some “significant way.” Id. at *19. The district court found that features at issue in the case were not claimed in the subject patents, elaborating as follows:\

[T]here is a massive potential for jury confusion here if these things are used in the way, frankly, that they were used during the cross-examination of the [ ] expert. You put a picture up there, that’s got a handle, it’s got a knob, it’s got a plunger, it’s cylindrical like yours, that’s not what the inquiry is. The inquiry isn’t whether somebody has drawn this picture before. The inquiry is whether ... the features are claimed in a patent in a way that shows that they have some sort of a function.

Id. at *20 (quoting the district court).

The Seventh Circuit agreed with the district court. The court cited TrafFix Devices, Inc. v. Mktg. Displays, Inc., 532 U.S. 23, 28–29 (2001), and Georgia-Pacific Cons. Prods., LP v. Kimberly-Clark Corp., 647 F.3d 723, 727–28 (7th Cir. 2011), in support.

In framing the court’s analysis, the court pointed out that the “patents A Top sought to introduce do not claim any of the features that comprise the claimed Chambord trade dress.” See TrafFix Devices, 532 U.S. at 29 (utility patents are evidence ‘that the features therein claimed are functional’ (emphasis added)).” Bodum, 2019 U.S. App. LEXIS 17555, at *20–21. The court further stated that the particular patents, which at least appeared to show “French presses with handles, domed lids, or knobs; are irrelevant to the legal question of functionality because the patents do not claim any of those features as part of the patented invention. Permitting the jury to view and consider the patents would cause confusion as to the appropriate inquiry for functionality.” Id. at *21 (emphasis added). Finally, the court distinguished the case below (in which the district court properly excluded utility patents that did not claim the trade dress elements) from a prior case in which the court had reversed a district court that had determined on summary judgment that the feature claimed in the patent was not functional, saying that the matter of whether the claim feature was part of the functionality or just “incidental” was a matter for the jury. Id. at *22.

The case is most interesting because of the way the court handled the utility patent evidence. “Trade dress is always a difficult claim to prove, and this victory is paramount to our client, Bodum’s, protection of its brand going forward.” The decision indicates that the court clearly drew the line on use of the utility patents at whether the trade dress element was claimed in those patents or not. Its language supporting the district court’s decision repeatedly made reference to the fact that the utility patents did not claim the particular elements of Bodum’s trade dress. Further, the court distinguished an earlier case in which utility patents were required to be considered by a jury based on the fact that the feature at issue there was in the claims. The court’s decision not only limits the applicability of utility patents in trade dress cases, it suggests that such patents may not even be admissible unless the party introducing those patents into evidence can point to the trade dress elements in the claims.
