Beware Enablement of Genus Antibody Claims

by | Oct 5, 2023 |

The US Court of Appeals for the Federal Circuit invalidated yet another set of antibody genus claims, finding the case “materially indistinguishable” from those in the 2023 Supreme Court of the United States case, Amgen v. Sanofi. The Federal Circuit concluded that patent claims covering a class of antibodies targeting functions of blood clotting factors were invalid for lack of enablement, echoing the reasoning followed by fellow Circuit Judge Dyk, who sat by designation in the district court. Baxalta Inc. and Baxalta GMBH v. Genentech, Inc., Case No. 2022-1461 (Fed. Cir. Sept. 20, 2023) (Moore, Clevenger, Chen, JJ.)

This case involves Baxalta’s patent covering antibody preparations that bind to blood clotting Factors IX/IXa and thereby increase the procoagulant activity of Factor IXa. This in turn activates another blood clotting factor, Factor X, that is useful to treat hemophilia, particularly in patients who develop inhibitors to blood clotting Factor VIII. The claim at issue recited “[a]n isolated antibody or antibody fragment thereof that binds Factor IX or Factor IXa and increases procoagulant activity of Factor IXa.”

Baxalta sued Genentech for infringement. In a prior appeal involving claim construction, the Federal Circuit vacated the district court’s grant of summary judgment of noninfringement and remanded for further proceedings. On remand, the district court granted Genentech’s motion for summary judgment for lack of enablement. Baxalta appealed.

Baxalta challenged the summary judgment of invalidity on enablement. Baxalta argued that a skilled artisan could make the full scope of the claimed antibodies without undue experimentation. With reference to the subject patent’s disclosure of using a prior art method known as the hybridoma technique for generating Factors IX/IXa antibodies, Baxalta argued that using routine screenings to find the antibodies exhibiting the claimed functions (i.e., those that bind Factors IX/IXa and increase procoagulant activity of Factor IXa) was within the skill of a skilled artisan without undue experimentation.

The Federal Circuit, citing Amgen, explained that the enablement standard under Section 112(a) requires that “the specification [] enable the full scope of the invention as defined by its claims,” allowing for “a reasonable amount of experimentation.” The Court explained that in Amgen, the patents at issue generically claimed all antibodies that bind to specific amino acid residues on a protein and blocked the protein from binding to LDL receptors. The Court observed that while the Amgen patent disclosed amino acid sequences of 26 antibodies, the claim scope could cover millions. Similarly, the Amgen patent disclosed a roadmap and another conservative substitution method for generating new antibodies and testing them for the claimed functions. In Amgen, the Supreme Court held that such methods were nothing more than “trial-and-error experimentation,” which, in the absence of “some general quality . . . running through the class that gives it a peculiar fitness for the particular purpose,” failed to enable the full scope in that case.

The Federal Circuit found the facts in this case “materially indistinguishable” from Amgen. Like the claims at issue in Amgen, Baxalta’s patent claims all [...]

No Need To Be Explicit: Implicit Finding of Expectation of Success Is Sufficient

by | Oct 5, 2023 |

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board unpatentability decision, finding that a combination of prior art references only requires an implicit indication of a reasonable expectation of success. Elekta Ltd. v. Zap Surgical Systems, Case No. 21-1985 (Fed. Cir. Sept. 21, 2023) (Reyna, Stoll, Stark JJ.)

Elekta owns a patent directed to a “method and apparatus for treatment by ionizing radiation.” The claimed invention uses a radiation source such as a linear accelerator (linac) mounted on concentric rings to deliver a beam of ionizing radiation to a target area on the patient. Zap challenged the patent as obvious in an inter partes review (IPR) proceeding. In its Final Written Decision, the Board agreed, concluding that a skilled artisan would have been motivated to combine the asserted prior art references. Elekta appealed.

Elekta raised three arguments on appeal:

  1. The Board’s findings on motivation to combine were not supported by substantial evidence.
  2. The Board failed to make any findings (explicit or implicit) on a reasonable expectation of success.
  3. Even if the Board made such findings, they were not supported by substantial evidence.

The Federal Circuit first considered the issue of motivation to combine the prior art references disclosing radiation imagery with references disclosing radiation therapy, noting that the obviousness determination does not always require the prior art to expressly state a motivation for every obviousness combination. Elekta had challenged the asserted combination based on a physical impracticality in combining the art due to the weight of the linac. The Board, however, disagreed largely because of the level of skill in the art in addition to its definition of the relevant field as one that “includes the engineering design of sturdy mechanical apparatuses capable of rotationally manipulating heavy devices.” The Court found that the Board’s finding of motivation to combine was supported by substantial evidence, including the prosecution history, the prior art teaching and the expert testimony of record.

The Federal Circuit next considered Elekta’s argument that the Board erred by failing to articulate findings on reasonable expectation of success. The Court explained that “an obviousness determination requires finding that a person of ordinary skill in the art would have had a reasonable expectation of success,” referring to “the likelihood of success in combining references to meet the limitations of the claimed invention.” The Court concluded, however, that unlike the motivation to combine determination, which must be an explicit analysis under KSR, a finding of reasonable expectation of success may be implicit. The Court acknowledged that this could be seen as being in tension with its review of Board determinations under the Administrative Procedure Act but concluded that “there is no such tension where the Board makes an implicit finding on reasonable expectation of success by considering and addressing other, intertwined arguments, including . . . those [regarding] a motivation to combine.”

Finally, the Federal Circuit addressed Elekta’s argument that, even if the Board made an implicit finding on reasonable expectation of [...]

Seeking Harmony: Supreme Court to Consider Retrospective Relief for Timely Copyright Claims Under Discovery Rule

by | Oct 5, 2023 |

The Supreme Court of the United States agreed to consider whether a copyright plaintiff’s timely claim under the discovery rule is subject to retrospective relief for infringement occurring more than three years before the suit was filed. Warner Chappell Music, et al. v. Nealy, Case No. 22-1078 (Supr. Ct., Sept. 29, 2023) (certiorari granted). The specific question presented is as follows:

Whether, under the discovery accrual rule applied by the circuit courts and the Copyright Act’s statute of limitations for civil actions, 17 U. S. C. §507(b), a copyright plaintiff can recover damages for acts that allegedly occurred more than three years before the filing of a lawsuit.

Music Specialist and Sherman Nealy (collectively, Nealy) filed a copyright infringement suit against Warner alleging that Warner was using Nealy’s musical works based on invalid third-party licenses and in violation of 17 U.S.C. § 501. The alleged copyright infringement occurred as early as 10 years before Nealy filed the lawsuit. The district court denied Warner’s motion for summary judgment on statute of limitation grounds, finding that there was a genuine dispute of material fact regarding when Nealy’s claim accrual occurred. In a separate order, the district court certified for interlocutory appeal whether “damages in this copyright action are limited to the three-year lookback period as calculated from the date of the filing of the Complaint pursuant to the Copyright Act and Petrella.” Warner appealed.

The US Court of Appeals for the Eleventh Circuit agreed with the district court, issuing a decision that where a copyright plaintiff has a timely claim for infringement occurring more than three years before the filing of the lawsuit, the plaintiff may obtain retrospective relief for that infringement.

The Eleventh Circuit’s approach specifically disagreed with the Second Circuit’s approach to the application of the discovery rule, thereby creating a circuit split.

What’s Kühler Than Kühl? No Likelihood of Confusion

by | Sep 28, 2023 |

Addressing unfair competition claims under the Lanham Act, the US Court of Appeals for the Tenth Circuit concluded that no reasonable juror would confuse an alcohol distributer’s use of the word “kühl” with use of a similar mark by a clothing company. Alfwear, Inc. v. Mast-Jägermeister US, Inc., Case No. 21-4029 (Fed. Cir. Sept. 7, 2023) (Holmes, Kelly, Carson, JJ.)

Alfwear has used the mark KÜHL on its outdoor apparel line since 1993 and has registered the mark in connection with apparel, wine and beer. Mast-Jägermeister US (MJUS), a German herbal liqueur distributor, began incorporating “kühl” into its advertisements on billboards, commercials and digital advertising in phrases such as “kühl as ice” and “drink it ice kühl.” In response, Alfwear filed suit against MJUS, asserting trademark infringement and unfair competition. The district court granted MJUS’s motion for summary judgment, finding that there was no likelihood of confusion because all but one factor for assessing likelihood of confusion supported MJUS. Alfwear appealed.

Alfwear argued that the district court erred by not concluding that MJUS’s use of the word “kühl” was likely to cause confusion with Alfwear’s use of the essentially the same word. To determine whether a likelihood of confusion exists, the following factors must be considered:

  • The degree of similarity between the marks
  • The intent of the alleged infringer in adopting its mark
  • Evidence of actual confusion
  • Similarity of products and manner of marketing
  • The degree of care likely to be exercised by purchasers
  • The strength or weakness of the marks.

The Tenth Circuit found that the two marks were not similar in sound, meaning or appearance, and that MJUS only used “kühl” in association with other MJUS marks. The Court explained that Alfwear often depicts the KÜHL mark alongside a logo of a shield-type shape containing a stylized, snow-covered mountain peak in the colors brown, black and white against a bright blue sky. In contrast, MJUS uses the word “kühl” in phrases such as “kühl shots” or “kühl as ice,” on top of a black or green background and accompanied by a combination of either the mark JÄGERMEISTER, the Jägermeister logo or images of a Jägermeister bottle.

The Tenth Circuit also found that MJUS did not intend to copy Alfwear’s mark, explaining that MJUS was not aware of Alfwear’s trademark when designing the new advertising campaign, and noting that when MJUS became aware of the trademark, MJUS intended to avoid infringement by not placing the mark on its apparel or liquor products. The Court also determined that there was insufficient evidence of actual confusion. Alfwear presented anecdotal evidence from Alfwear executives who had heard about confusion from individuals and survey evidence that demonstrated consumers experienced an approximately 30% chance of confusion. The Court found that the anecdotal evidence was de minimis and found that the survey was not designed properly because the products were not shown to survey participants as they would appear in the marketplace and used leading questions. The Court also found that the two [...]

Grubhub Relishes Victory Against Trademark Preliminary Injunction

by | Sep 28, 2023 |

Upholding the denial of a preliminary injunction motion in a trademark infringement dispute, the US Court of Appeals for the Seventh Circuit concluded that the district court did not err in finding that the trademark owner failed to show a likelihood of success on its reverse confusion theory. Grubhub Inc. v. Relish Labs LLC, Case No. 22-1950 (7th Cir. Sept. 12, 2023) (Lee, Jackson-Akiwumi, Wood, JJ.)

Relish Labs and the Kroger Company (Home Chef) create and deliver meal kits with pre-portioned ingredients that customers can cook at home. Home Chef began using its “HC Home Mark,” which is protected by five federal trademark registrations, in 2014. Home Chef has spent more than $450 million on advertising and reached $1 billion in annual sales in October 2021.

Grubhub is an online food ordering and delivery service that provides on-demand order management, dispatching and procurement. In June 2021, Grubhub was acquired by Netherlands-based Just Eat Takeaway (JET), an international food delivery company that typically combines its “JET House Mark” with the marks of its local brands.

Before finalizing its acquisition of Grubhub, JET filed an international trademark application for the JET House Mark. However, the US Patent & Trademark Office (PTO) examiner preliminarily rejected the mark, finding it to be “confusingly similar” to the HC Home Mark. JET did not respond and withdrew the application. After acquiring Grubhub, JET adopted the “Grubhub House Logo,” which combined the Grubhub logo with the JET House Mark. Grubhub introduced the new logo in July 2021 and has spent millions of dollars rebranding.

After receiving a cease-and-desist letter from Home Chef, Grubhub sued, seeking a declaratory judgment that its logo did not infringe Home Chef’s marks. Home Chef countered with a motion for preliminary injunction, which was referred to a magistrate judge. The magistrate judge recommended that the court grant Home Chef preliminary injunctive relief, but the district court rejected the recommendation and denied Home Chef’s motion, finding that it had not shown a likelihood of success on the merits. Home Chef appealed.

On appeal, the Seventh Circuit began by addressing which Grubhub mark was at issue: the JET House Mark alone or the Grubhub House Logo (which incorporated the logo portion of the JET House Mark). The Court noted that Grubhub had not used the JET House Mark without the Grubhub brand name in the United States and thus agreed with the district court that the accused mark was the Grubhub House Logo:

Turning next to Home Chef’s reverse confusion theory, the Seventh Circuit addressed the relevant four factors [...]

Standard Practice: The Public Has Right to Copyrighted Material Incorporated Into Law

by | Sep 28, 2023 |

In a case that attracted a slew of amicus curiae participation and was the most recent in the series of American Society for Testing and Materials (ASTM) copyright cases, the US Court of Appeals for the District of Columbia Circuit affirmed the district court’s holding that the noncommercial dissemination of standards, as incorporated by reference into law, constitutes fair use and thus does not support liability for copyright infringement. Am. Soc’y for Testing & Materials v. Public.Resource.Org, Case No. 22-7063 (DC Cir. Sept. 12, 2023) (Henderson, Pillard, Katsas, JJ.)

The ASTM and the other plaintiffs are private organizations that develop and promulgate standards for establishing best practices for their respective industries or products. In 2013, they brought an action for copyright infringement against Public.Resource.Org for posting their copyrighted standards (as they were referenced in agency rulemaking and incorporated into law) on its website, thereby making these materials available to the public at no cost. After the district court initially granted ASTM’s motion for summary judgment of copyright infringement and rejected Public Resource’s fair use defense, the DC Circuit reversed and remanded for further consideration the issue of whether posting the incorporated standards constituted fair use. Subsequently, the district court “found fair use as to the posting of standards incorporated into law and infringement as to the standards not so incorporated.” The plaintiffs appealed.

On appeal, the DC Circuit analyzed the following fact-intensive fair use factors:

  • The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes
  • The nature of the copyrighted work
  • The amount and substantiality of the portion used in relation to the copyrighted work as a whole
  • The effect of the use upon the potential market for or value of the copyrighted work.

The DC Circuit concluded that the first three factors strongly favored holding that Public Resource’s posting of the incorporated standards constituted fair use. As to the first factor, the Court explained that in a manner similar to the one discussed by the Supreme Court of the United States in its 2021 Google v. Oracle Am. case, Public Resource’s use was for nonprofit, noncommercial educational purposes. The DC Circuit further found Public Resource’s use transformative in that it served different purposes than ASTM’s use (“provide[ing] the public with a free and comprehensive repository of the law” versus “producing standards reflecting industry or engineering best practices.”)

As to the second factor, the DC Circuit reasoned that the “nature of the copyrighted work” heavily favored fair use because the standards “fall at the factual end of the fact-fiction spectrum” and “have legal force, [such that] they . . . fall ‘at best, at the outer edge of copyright’s protective purposes.’” As to the third factor, the Court found that it strongly supported fair use because the standards had been incorporated and thus had “the force of law.”

With respect to the fourth factor, the DC Circuit recognized that Public Resource’s [...]

Chilly Adventures: Design Patent Prior Art Comparison Applies to Article of Manufacture

by | Sep 28, 2023 |

Addressing a matter of first impression concerning the scope of prior art relevant to a design patent infringement analysis, the US Court of Appeals for the Federal Circuit concluded that “to qualify as comparison prior art, the prior-art design must be applied to the article of manufacture identified in the claim.” Columbia Sportswear North America, Inc. v. Seirus Innovative Accessories, Inc., Case Nos. 21-2299; -2338 (Fed. Cir. Sept. 15, 2023) (Prost, Reyna, Hughes, JJ.)

Columbia owns a design patent that covers an ornamental design of a heat reflective material. Seirus markets and sells products (e.g., gloves) made with material that it calls HeatWave. An image of Columbia’s patented design and Seirus’s HeatWave material appear below:

Columbia Patented Design

Seirus HeatWave

Columbia sued Seirus for infringement. After the district court granted summary judgment of infringement, Seirus appealed to the Federal Circuit. The Court issued its decision in Columbia I, concluding that the district court improperly declined to consider the effect of Seirus’s logo in its infringement analysis and resolved certain issues that should have been left to the jury. The Court therefore vacated summary judgment and remanded for further proceedings.

On remand, the district court held a trial. Before trial, the district court limited admissible comparison prior art to “wave patterns of fabric,” declined to instruct the jury that “prior art” referred to prior designs of the claimed article of manufacture, and declined to instruct the jury that it did not need to find that any purchasers were deceived or that there was any actual or likelihood of confusion among consumers in the marketplace. Seirus was permitted to admit three prior art references that disclosed fabric, and Columbia was precluded from distinguishing the references by arguing that they did not disclose heat reflective material. The jury returned a verdict of noninfringement. Columbia appealed.

Among other things, Columbia challenged the exclusion of evidence and jury instructions concerning comparison prior art, and the jury instructions implicating Seirus’s logo.

The Federal Circuit began by discussing the appropriate prior art comparison in the context of design patent infringement. Citing its 2008 en banc decision in Egyptian Goddess v. Swisa, the Court explained that under the ordinary-observer test governing design patent infringement, prior art can help highlight distinctions and similarities between the claims and the accused design. For instance, when a claimed design is close to a prior art design, small differences between the accused design and the claim design are likely to be important. Conversely, if an accused design copied a particular feature of the claimed design that departs from the prior art, the accused design is likely to be regarded as deceptively similar to the claimed design, and thus infringing.

The question of first impression before the Federal Circuit was the proper scope of comparison prior art that [...]

Head East: Contract Disputes Act Claims Must Be Filed in DC

by | Sep 28, 2023 |

The US Court of Appeals for the Ninth Circuit concluded that the Contract Disputes Act (CDA) “impliedly forbids” federal contractors from bringing most trade secret misappropriation claims against federal agencies in district court. Instead, the CDA requires contractors to bring such claims before the US Court of Federal Claims or the agency board of contract appeals, both of which are located in Washington, DC. United Aeronautical Corp. v. United States Air Force, Case No. 21-56377 (9th Cir. Sept. 7, 2023) (Smith, Lee, JJ.) (Collins, JJ., dissenting).

United Aeronautical Corporation (Aero) develops firefighting products, including the Mobile Airborne Fire Fighting System for use in aerial firefighting. The US Forest Service contracted with Aero to develop an updated aerial system to assist the agency in fighting fires. The ensuing prototype necessarily incorporated significant amounts of Aero’s intellectual property. To protect that information, Aero and the Forest Service executed a Data Rights Agreement (DRA) providing that “the technical data produced . . . or used or related” to developing the prototype “shall remain the property of [Aero],” but specifying that the Forest Service “shall have unlimited rights to view and use the data required for the continued use and operation of the” prototype. The Forest Service proceeded to share Aero’s data with the Air Force, which developed an upgraded aerial firefighting system it marketed internationally.

Aero sued the Air Force for misappropriating its trade secret information. Procedurally, Aero brought its claims under the Administrative Procedure Act (APA), seeking a declaration that the Air Force’s actions violated the Trade Secrets Act and federal procurement law, and an injunction prohibiting any further use of that data to develop competing products. Although the Air Force believed it was permitted to use Aero’s trade secrets pursuant to the DRA, it also argued that Aero’s complaint must be dismissed for lack of subject matter jurisdiction. The district court agreed, concluding that the CDA vests exclusive jurisdiction over federal-contractor disputes with the Court of Federal Claims where, as here, the dispute is related to a procurement contract. Aero appealed.

The Ninth Circuit affirmed the dismissal. Aero argued that the APA permits any “person suffering legal wrong[s] because of agency action” to seek redress in a federal district court and that the Air Force’s misappropriation of Aero’s trade secret information—in violation of the Trade Secrets Act—was exactly that. The Ninth Circuit disagreed, concluding that the nature of Aero’s claims (misappropriation, not breach of contract) and the relief it sought (an injunction, not damages or specific performance) mattered little. What mattered was the existence of a contract between the contractor and an agency that “related to” the intellectual property at issue.

Under the APA, a private party cannot bring suit when its claims are “impliedly forbidden” by a different statute that vests exclusive jurisdiction with another tribunal. The Ninth Circuit concluded that the CDA “impliedly forb[ade]” Aero’s claims since it was enacted to create a dispute resolution system for claims concerning federal procurement contracts, vesting exclusive jurisdiction of these disputes with [...]

Pre-Enforcement Commercialization Isn’t “Impossible” Basis for Personal Jurisdiction of Nonresident Defendant

by | Sep 28, 2023 |

The US Court of Appeals for the Ninth Circuit reversed a district court’s dismissal of trademark declaratory judgment claims, finding that pre-enforcement commercialization activities can be used to establish personal jurisdiction. Impossible Foods Inc. v. Impossible X LLC, Case No. 21-16977 (9th Cir. Sept. 12, 2023) (Lucero, Bress, JJ.) (VanDyke, J., dissenting).

Impossible Foods is a Delaware corporation manufacturing plant-based meat substitutes, including the “Impossible Burger.” Impossible X, a Texas LLC, is Joel Runyon’s one-person company selling apparel and nutritional supplements using a website and social media. San Diego, California, was Impossible X’s “base point” for two years, serving as Runyon’s apartment and workspace. A LinkedIn profile listed San Diego as the headquarters, and social media frequently tagged San Diego as Impossible X’s location. When vacating his lease, Runyon signed the document as “Joel Runyon, Impossible X LLC.” Even after leaving, Runyon took at least eight trips to California between 2017 and 2019 for the purpose of performing Impossible X work and promoting the Impossible brand.

In 2020, Impossible X filed a notice of opposition at the Trademark Trial & Appeal Board for Impossible Food’s trademark application. Impossible Foods responded with a declaratory judgment action in 2021 in California, seeking a finding of noninfringement and that its rights to the IMPOSSIBLE mark were superior. Impossible X sought dismissal, arguing that the district court lacked personal jurisdiction.

The criteria to establish specific personal jurisdiction over a nonresident defendant are as follows:

  • The defendant must purposefully direct its activities toward the forum or purposefully avail itself of the privileges of conducting activities in the forum.
  • The claim must arise out of or relate to the defendant’s forum-related activities.
  • Exercise of jurisdiction must be reasonable.

The district court acknowledged that the personal jurisdiction question here was a “close one” and concluded that while Impossible Foods satisfied the purposeful direction or availment requirement, the declaratory judgment action did not arise out of or relate to Impossible X’s contact with California. Impossible Foods did not begin use of its mark in commerce until June 2016, at which point Runyon had already left California. The district court found that the parties did not have a live dispute until June 2016, and Impossible X’s contacts with California prior to that time were irrelevant to personal jurisdiction. Impossible Foods appealed.

The Ninth Circuit analyzed each prong of the jurisdiction test and reversed the dismissal. First, the Court agreed with the district court that Impossible X purposefully directed activities toward California and availed itself of privileges of conducting activities by building its brand and establishing trademark rights there. A court typically treats trademark infringement as tort-like for personal jurisdiction purposes and applies the purposeful direction framework. The Ninth Circuit explained that there is no need to adhere to an “iron-clad doctrinal dichotomy” between purposeful availment and direction, however. The Court leaned on “purposefulness” vis-à-vis the forum state and “easily” concluded that Impossible X purposefully directed its activities toward California and/or availed itself of the benefits and privileges [...]

Watermelon Sugar: Candy Shape and Color Deemed Functional

by | Sep 21, 2023 |

The US Court of Appeals for the Third Circuit upheld a district court’s decision that a candymaker cannot trademark the shape and colors of watermelon candy, finding that the combined colors and shape of the candy are functional because they help signal to consumers that the candies have a watermelon flavor. PIM Brands Inc. v. Haribo of America, Inc., Case No. 22-2821 (3rd Cir. Sept. 7, 2023) (Chagares, Bibas and Matey, JJ)

PIM is a leading confectionary company that introduced its Sour Jacks Wedges, a chewy gummy candy, in the early 2000s.

PIM obtained a federal trademark registration in “the shape of a wedge for candy, with an upper green section with white speckles, followed by a narrow middle white section and followed by a lower red section with white speckles.”

Haribo, a well-known German confectionery company, introduced its own watermelon-flavored sweet treat in 2019. Like the Sour Jacks Wedges, Haribo’s candy is red, white and green, with an elongated watermelon wedge shape. PIM sued Haribo for trademark and trade dress infringement under the Lanham Act and for unfair competition under New Jersey common law, alleging that Haribo copied PIM’s Sour Jacks Wedges design.

Haribo countered that PIM’s trade dress was functional and requested that the district court cancel PIM’s trademark. Haribo claimed that it designed its chewy candy’s shape and colors to match its flavor (watermelon) and that PIM’s trademark should not have been granted since it closely resembled an actual slice of watermelon. The district court agreed, finding that PIM’s trademark design was functional and not protectable since PIM’s combination of colors and shape helps identify the candy’s watermelon flavor. PIM appealed.

PIM acknowledged that the coloring of its watermelon candy was functional since it identified the candy’s flavor. However, PIM argued that the candy’s wedge shape identified the brand and challenged the district court’s decision because it did not consider the wedge shape in isolation from the colors when assessing functionality.

The Third Circuit rejected PIM’s argument, concluding that each feature of the candy’s trade dress serves a single function, which is to identify its flavor, and therefore is ineligible for trademark protection. The Court explained that a design is functional if it is useful for anything beyond branding. The Court cited to its 2021 decision in Ezaki Glico v. Lotte International America, explaining that “[e]ven if the design chosen both promotes a brand and also ‘makes a product work better,’ it is functional and unprotectable.” The Court went on to explain that if design choices (e.g., shape and color) serve the same function (e.g., identifying the flavor), they should be considered together.

PIM further argued that its Sour Jacks Wedges do not match exactly with watermelon, noting that the bottom could be more curved and have a thinner band of darker green, the wedge could be wider, the point could be sharper and a deeper red, and there could be black seeds. [...]
