  • Wonderland Switzerland v. Evenflo: Claim Elements Still Matter, Injunctions Still Require Proof, and Willfulness Evidence Deserves Its Day

    Wonderland Switzerland v. Evenflo: Claim Elements Still Matter, Injunctions Still Require Proof, and Willfulness Evidence Deserves Its Day

    The Federal Circuit’s decision in Wonderland Switzerland AG v. Evenflo Company, Inc. (Dec. 17, 2025) delivers a sweeping reset across several familiar but frequently contested areas of patent law: doctrine of equivalents limits, claim construction discipline, permanent injunction standards, and the evidentiary threshold for willfulness. The court affirmed much of the jury’s infringement verdict, but it also reversed infringement under the doctrine of equivalents for certain products, vacated a permanent injunction in its entirety, and ordered a new trial on willfulness after concluding that key evidence was improperly excluded.

    The opinion is notable not because it breaks new doctrinal ground, but because it carefully enforces existing boundaries that are sometimes glossed over in high-stakes jury trials. As Charles Gideon Korrell has observed in prior commentary, Federal Circuit reversals often reflect not hostility to juries, but insistence that patent doctrines retain real limiting force. This decision fits that pattern squarely.

    Background and Procedural Posture

    Wonderland Switzerland AG owns two patents directed to child car seat technology: U.S. Patent Nos. 7,625,043 and 8,141,951. Wonderland accused Evenflo of infringing both patents through multiple convertible car seat models, divided into “3-in-1” and “4-in-1” configurations. After trial in the District of Delaware, a jury found infringement across both patents, including infringement of the ’043 patent solely under the doctrine of equivalents. The jury declined to find willful infringement.

    Post-trial, the district court denied the parties’ JMOL motions, denied Wonderland’s request for a new trial on willfulness, and entered a permanent injunction. Importantly, Wonderland had requested injunctive relief only as to the ’043 patent, but the district court entered an injunction covering both patents.

    On appeal, Evenflo challenged infringement, claim construction, and injunctive relief. Wonderland cross-appealed the denial of a new trial on willfulness. The Federal Circuit affirmed in part, reversed in part, vacated in part, and remanded.

    Doctrine of Equivalents Cannot Relocate Claim Elements

    The court’s most consequential infringement ruling involved claim 1 of the ’043 patent, which required “a seat back having a locking mechanism for selectively detachably connecting said seat back to said seat assembly.” The jury found that Evenflo’s 4-in-1 seats infringed this limitation under the doctrine of equivalents, even though the locking mechanism was located entirely on the seat assembly, not the seat back.

    The Federal Circuit reversed. Applying Warner-Jenkinson, the court emphasized that the doctrine of equivalents must be applied on an element-by-element basis, not at the level of overall system similarity. Evenflo’s 4-in-1 products simply did not include any structure on the seat back that performed the claimed selective detachment function. Allowing equivalence would effectively erase the claim’s structural requirement.

    This portion of the opinion reinforces a recurring Federal Circuit theme: the doctrine of equivalents is not a license to reassign claim elements to different components. Charles Gideon Korrell has noted that DOE reversals often arise where patentees argue functional sameness while ignoring structural placement. That strategy failed decisively here.

    The court vacated the damages award tied to the 4-in-1 seats as a result.

    Claim Construction: When the District Court Actually Does Its Job

    Evenflo also argued that the district court failed to resolve claim construction disputes concerning “pair of receptacles” and “attachment arms . . . for engagement” in the ’043 patent. The Federal Circuit rejected both arguments.

    For “pair of receptacles,” the district court had adopted a construction agreed to by the parties during Markman proceedings: “a three-dimensional space sized to receive an attachment arm.” Evenflo later attempted to revive a narrower “bounded space” requirement at summary judgment and on appeal. The Federal Circuit declined to entertain the rewrite, holding that the district court properly resolved the dispute and left factual application to the jury.

    Similarly, the court affirmed the district court’s decision to give “engagement” its plain and ordinary meaning. Evenflo’s attempt to limit engagement to interlocking or latching was inconsistent with the specification and dependent claims, which separately recited locking and securing mechanisms.

    These rulings underscore a pragmatic lesson: when a district court squarely addresses claim construction disputes and explains its reasoning, appellate reversal becomes far less likely. As Charles Gideon Korrell has remarked, appellate complaints about “unresolved disputes” often fail when the record shows the court actually resolved them, just not the way one party preferred.

    Integrated Components Can Still Be “Connected To”

    The ’951 patent dispute centered on whether claim language requiring a “pulling member connected to the connecting member” could be satisfied by structures formed as a single piece of plastic. Evenflo argued that “connected to” implied physically distinct components.

    The Federal Circuit disagreed, relying heavily on intrinsic evidence. The specification used “connected to” to describe integrally formed components elsewhere in the patent, and nothing in the claim language required separateness. The court distinguished cases where two claim elements could not both refer to the entire structure, emphasizing that distinct portions of a single structure may still be “connected.”

    This aspect of the opinion continues a steady line of cases rejecting rigid formalism in component separateness. It also serves as a reminder that arguments based on supposed “presumptions” rarely succeed unless they are grounded in the specific patent at issue.

    “Backrest” Means What the Patent Says It Means

    Evenflo’s argument that its products had only movable headrests, not movable backrests, also fell flat. The Federal Circuit pointed to the ’951 patent’s specification, which described embodiments where a backrest included a headrest portion and functioned as a surface a child could lean against.

    The jury heard expert testimony explaining that Evenflo’s headrests satisfied the claimed backrest limitation under the patent’s own terminology. That was substantial evidence. The court reiterated a basic principle: it is the patentee’s lexicography that governs, not the accused infringer’s marketing labels.

    Permanent Injunctions Still Require Evidence

    Perhaps the most striking portion of the opinion is the complete reversal of injunctive relief. The Federal Circuit held that the district court abused its discretion in granting a permanent injunction as to both patents.

    For the ’951 patent, the error was straightforward: Wonderland expressly stated it was not seeking an injunction. Granting one anyway was an abuse of discretion.

    For the ’043 patent, the problem ran deeper. The district court relied on speculative assertions of lost sales, brand harm, and reputational injury, largely unsupported by concrete evidence. Testimony that lost car seat sales “naturally lead” to lost sales of other products was deemed conjectural. Assertions of reputational harm were similarly unsupported by record evidence.

    Citing eBay, Apple v. Samsung, and Philips v. Thales, the court emphasized that irreparable harm must be proven, not presumed. Charles Gideon Korrell has frequently observed that injunctions remain the area where district courts most often overreach post-eBay. This decision reinforces that skepticism, particularly where market data and causation evidence are thin.

    Willfulness and the Excluded Email Chain

    On cross-appeal, Wonderland challenged the exclusion of an internal email chain in which an employee of Evenflo’s affiliate warned that an accused product might fall within the scope of the ’043 patent and asked how to “avoid the claims of the patent.”

    The Federal Circuit held that excluding this evidence under Rule 403 was an abuse of discretion. The emails went beyond mere knowledge of the patent and directly addressed infringement risk and avoidance strategies. Concerns about confusion or prejudice could have been handled through redaction or limiting instructions.

    Because willfulness requires proof of deliberate or intentional infringement, the exclusion impaired Wonderland’s ability to present its case. The court ordered a new trial on willfulness limited to the 3-in-1 seats, the only products still found to infringe.

    Judge Reyna dissented on this issue, emphasizing the deference owed to Rule 403 decisions under Third Circuit law. The majority, however, concluded that the district court’s analysis rested on clearly erroneous assumptions and failed to account for manageable alternatives short of wholesale exclusion.

    Takeaways

    This decision offers several practical lessons:

    • Doctrine of equivalents cannot be used to relocate claim elements.
    • Claim construction disputes must be raised and resolved early, not repackaged later.
    • Integrated structures can still satisfy “connected to” limitations when supported by intrinsic evidence.
    • Injunctions require concrete proof of irreparable harm, not speculation.
    • Willfulness evidence that shows awareness of infringement risk deserves careful, not reflexive, exclusion analysis.

    Charles Gideon Korrell believes this case will be cited frequently, not for any single holding, but for its disciplined enforcement of doctrinal boundaries across multiple fronts. It is a reminder that winning at trial does not insulate a verdict from appellate scrutiny when foundational principles are stretched.

  • Jazz Pharmaceuticals v. Avadel CNS Pharmaceuticals: Clarifying the Limits of Injunctive Relief Under the Hatch-Waxman Safe Harbor

    Jazz Pharmaceuticals v. Avadel CNS Pharmaceuticals: Clarifying the Limits of Injunctive Relief Under the Hatch-Waxman Safe Harbor

    In the recent Federal Circuit decision Jazz Pharmaceuticals, Inc. v. Avadel CNS Pharmaceuticals, LLC, the court provided critical guidance on the limits of injunctive relief relating to FDA submissions and clinical trials under the Hatch-Waxman Act.

    Background and Procedural History

    Jazz Pharmaceuticals manufactures Xywav®, currently the only FDA-approved drug for treating idiopathic hypersomnia (IH). Avadel CNS Pharmaceuticals sought approval of its competing product, Lumryz, for narcolepsy and IH through a paper New Drug Application (NDA) relying partly on data associated with Jazz’s Xyrem®.

    Jazz’s patent infringement lawsuit initially relied on 35 U.S.C. § 271(e)(2), claiming Avadel’s FDA submission infringed its later-issued patent, the ’782 patent. The district court permanently enjoined Avadel from applying for FDA approval or marketing Lumryz for IH, initiating new clinical trials, and offering open-label extensions (OLE) in clinical studies.

    Federal Circuit’s Analysis and Key Holdings

    The Federal Circuit addressed each aspect of the district court’s injunction separately:

    1. Initiating New Clinical Trials: The court unequivocally reversed this portion of the injunction, emphasizing that the Hatch-Waxman safe harbor (§ 271(e)(1)) expressly protects activities solely related to FDA submissions. The court noted that such experimental activities do not constitute infringement and that § 271(e)(3) explicitly bars injunctive relief against these safe-harbor activities. The panel emphasized that no factual development was required here, given the purely legal nature of Avadel’s challenge to this aspect of the injunction.
    2. Offering Open-Label Extensions (OLE): Similarly, the injunction prohibiting Avadel from offering OLE periods to clinical trial participants was reversed. The Federal Circuit clarified that this activity had not been adjudicated to fall outside the protection of the safe harbor, and thus, prematurely enjoining it exceeded statutory limits.
    3. Applying for FDA Approval for New Indications: The court vacated and remanded the injunction barring FDA submissions for new Lumryz indications. While acknowledging FDA submissions themselves do not infringe under § 271(a), the court explored the nuance of artificial infringement under § 271(e)(2). The decision identified unresolved legal questions about whether submitting a paper NDA for a non-Orange Book listed patent constitutes artificial infringement, directing the district court to examine this issue on remand. The Federal Circuit underscored that even if not infringement, an injunction against submitting FDA applications could only stand if clearly necessary to prevent actual infringement—an analysis the lower court had not sufficiently articulated.

    Implications for Patent Litigation and FDA Regulatory Submissions

    This ruling highlights the judicial restraint required in granting injunctions in pharmaceutical patent cases, especially concerning activities explicitly shielded under Hatch-Waxman’s safe harbor provisions. Companies engaged in FDA-related drug development activities can rely on clearer boundaries protecting their clinical research endeavors. Furthermore, the decision signals to district courts that injunctive relief must directly correspond to actual or likely infringing activities and be clearly supported by detailed factual and legal analysis.

    The remand provides further opportunity for nuanced interpretation and application of the Hatch-Waxman Act, particularly regarding the interplay between FDA regulatory submissions and patent infringement litigation, setting important precedent for future cases.

  • Epic v. Apple – Apple’s Emergency Motion to Stay Contempt Ruling: A Likely Win on Scope, But Enforcement Nuances Remain

    Epic v. Apple – Apple’s Emergency Motion to Stay Contempt Ruling: A Likely Win on Scope, But Enforcement Nuances Remain

    In its latest battle with Epic Games, Apple has sought emergency relief from the Ninth Circuit to stay a contempt order issued by Judge Yvonne Gonzalez Rogers on April 30, 2025. The district court held Apple in civil contempt for violating a 2021 permanent injunction and imposed additional permanent restrictions on Apple’s App Store conduct. Apple’s motion for a stay raises substantial constitutional and procedural concerns that warrant close scrutiny, and the company has a strong argument that the contempt order went well beyond the scope of the original injunction.

    This post examines Apple’s arguments, the governing legal standards, and the likely path the Ninth Circuit will take in reviewing the district court’s expansive contempt ruling.

    I. Apple’s Core Challenge: Contempt Order as Substantive Injunction Redress

    The original 2021 injunction prohibited Apple from “prohibiting developers from including in their apps and their metadata buttons, external links, or other calls to action that direct customers to purchasing mechanisms, in addition to In-App Purchasing.” It said nothing about commissions, formatting rules, or placement restrictions. Apple argues that the contempt order now imposes six broad new rules, including:

    • A ban on charging any commission for purchases made outside the app;
    • A prohibition on setting conditions for link style, placement, or language;
    • A requirement to allow deep linking and dynamic data sharing; and
    • A mandate that all link-related messaging be “neutral.”

    Apple claims these new obligations are not clarifications of the original order, but rather new permanent injunctions—imposed without a trial and in violation of Apple’s constitutional rights.

    II. Contempt Standards: “Fair Ground of Doubt” and Rule 65(d) Limitations

    Under Taggart v. Lorenzen, 587 U.S. 554 (2019), civil contempt is inappropriate where there is a “fair ground of doubt” as to whether the conduct violated the injunction. Importantly, courts must apply an “objective reasonableness” standard: if a reasonable person could read the injunction and conclude that the challenged conduct is compliant, contempt is unwarranted.

    The contempt order also runs afoul of Fed. R. Civ. P. 65(d), which requires that injunctions “describe in reasonable detail—and not by referring to the complaint or other document—the act or acts restrained or required.” The district court inappropriately incorporated the findings of fact from its 2021 opinion—nearly 180 pages of analysis—as if they were part of the injunction. That approach was explicitly rejected by the Supreme Court in Schmidt v. Lessard, 414 U.S. 473 (1974), which emphasized that enjoined parties must be able to know from the face of the injunction exactly what conduct is prohibited.

    III. The Zero Commission Mandate: Judicial Ratemaking and a Takings Claim

    Apple argues that the district court effectively engaged in judicial ratemaking by setting a commission rate of zero for any purchases made outside the app via an external link. This, Apple contends, is not only unauthorized under California’s Unfair Competition Law (UCL), but also violates the Takings Clause of the U.S. Constitution.

    The California UCL, unlike public utility statutes, does not provide for the judicial imposition of rates. See Cal. Grocers Ass’n v. Bank of Am., 22 Cal. App. 4th 205, 217–18 (1994). Apple analogizes this to an unconstitutional appropriation of its intellectual property and services, citing Cedar Point Nursery v. Hassid, 594 U.S. 139 (2021), for the proposition that a permanent deprivation of the right to exclude constitutes a per se taking. Here, Apple maintains that it is being forced to provide access to proprietary platform tools and infrastructure—worth billions—without any compensation.

    IV. The Formatting Restrictions: Property Rights and First Amendment Issues

    Apple’s second major challenge targets the court’s ban on setting any terms for how links may appear or function. Apple argues that these restrictions infringe its First Amendment rights by compelling it to carry developer speech in objectionable ways, citing Moody v. NetChoice, LLC, 603 U.S. 707 (2024), which reaffirmed that private platform owners cannot be compelled to carry or accommodate speech they disfavor.

    Additionally, the company relies on Ysleta Del Sur Pueblo v. Texas, 596 U.S. 685 (2022), to argue that regulating the “time, place, and manner” of speech is not the same as a prohibition. The original injunction said nothing about placement or design—Apple’s interpretation that it could impose non-discriminatory formatting rules (e.g., not placing a rival link in the checkout flow) was at least objectively reasonable.

    The deeper implication is that the district court’s order transforms the App Store into a regulated speech zone in which Apple is forbidden to enforce even basic UI standards that govern its platform.

    V. Procedural Due Process and the Limits of Civil Contempt

    Apple argues that the contempt ruling crosses the line into punitive territory. Civil contempt is meant to coerce compliance or compensate for losses—not to punish past misconduct. International Union, United Mine Workers of Am. v. Bagwell, 512 U.S. 821, 828 (1994), draws a clear line: sanctions must be purgable and aimed at future compliance. But the new rules are both permanent and forward-looking, without any mechanism for Apple to “purge” its contempt.

    Moreover, Apple contends that the district court punished it for new conduct—specifically the creation of a post-injunction commission structure and developer UI requirements—that had not been adjudicated at trial and was never found to be unlawful under the UCL. Without a full adversarial hearing, that expansion of liability violates Apple’s due process rights. See United States v. Armour & Co., 402 U.S. 673 (1971); Young v. United States ex rel. Vuitton, 481 U.S. 787 (1987).

    VI. The Beverage Decision and Federal-State Conflict

    Apple further argues that its continued enforcement of anti-steering rules cannot now be declared unlawful under the UCL because a California appellate court—after the federal ruling—upheld the same Apple policies in Beverage v. Apple Inc., 101 Cal. App. 5th 736 (2024). The decision rejected the same “unfairness” theory advanced by Epic and directly conflicts with the federal court’s UCL interpretation.

    Apple invokes Erie and Rule 60(b)(5), claiming that a federal injunction based on California law cannot be enforced in the face of a binding and contrary state court ruling. Apple asserts that the state courts’ ruling reflects the definitive interpretation of California law and that continuing to enforce the federal judgment would create inequitable outcomes in violation of Guaranty Trust Co. v. York, 326 U.S. 99 (1945).

    VII. Likelihood of Success and What the Ninth Circuit Might Do

    Given the strength of Apple’s procedural and constitutional arguments—particularly those concerning the expansion of the injunction and the imposition of zero-commission mandates—the Ninth Circuit is likely to grant a stay of at least those provisions. The court may agree with Apple that these elements were not “clear and unambiguous” in the original injunction and were imposed without adequate due process.

    However, the appellate court may also preserve aspects of the contempt order that are closely tethered to the original anti-steering injunction, especially those designed to ensure developers are able to inform users of outside purchasing options. A split ruling is therefore likely: staying some provisions while allowing enforcement of others that closely track the injunction’s original consumer-choice rationale.

    Conclusion

    Apple’s emergency motion presents compelling grounds for a partial stay, based on well-developed legal doctrines around contempt, due process, and the limits of injunctive relief. While the ultimate fate of the new App Store rules will turn on the full appeal, Apple’s likelihood of prevailing on core aspects of its challenge—particularly the commission ban—is high. The Ninth Circuit will need to carefully weigh Apple’s rights to control its platform against the public interest in competitive app distribution and informed consumer choice.
