Dyson Technology v. Schedule A Defendants: Design Patent Consent Judgment in 73 Days
Dyson Technology Limited brought a design patent infringement action in the Northern District of Illinois against anonymous e-commerce sellers operating on Walmart’s marketplace, asserting U.S. Patent No. D853,642 covering its hair styling apparatus. The case resolved in just 73 days via consent judgment, with defendants paying $5,000 in damages and accepting a permanent injunction.
Dyson’s Schedule A Strategy: Swift Design Patent Enforcement via Consent Judgment
On September 9, 2024, Dyson Technology Limited filed suit in the U.S. District Court for the Northern District of Illinois against a group of anonymous e-commerce sellers — identified on a sealed Schedule A — alleging infringement of U.S. Design Patent No. D853,642, which protects the ornamental design of Dyson’s hair styling and hair care apparatus. The defendants operated storefronts on Walmart’s marketplace, targeting U.S. consumers and accepting payment in U.S. dollars.
The case closed on November 21, 2024, via a court-entered consent judgment — a hybrid resolution combining a negotiated settlement with a binding judicial order. Three named defendants (foshanshihaobangyeshangmao, zhaoliangfashangmao, and Zhiding co., ltd) agreed to pay Dyson $5,000 in total damages and are now permanently enjoined from offering, selling, or importing the infringing products. Walmart was separately ordered to transfer the damages amount from defendants’ frozen accounts within seven days.
The 73-day resolution is notably rapid, consistent with the coercive effect of asset-freezing TROs that are standard in Schedule A cases filed in the N.D. Illinois. The $5,000 damages figure likely reflects a negotiated floor rather than full compensatory or statutory damages, suggesting defendants settled quickly to restore frozen accounts. The dismissal carries a 180-day reinstatement window, automatically converting to dismissal with prejudice if no motion to reinstate is filed — a mechanism that incentivises defendants to honour the settlement terms.

Consent judgment entered: what the order means for both parties
Consent judgment: a court-enforceable settlement
A consent judgment is not merely a private settlement — it is a court order that carries the full enforcement power of the judiciary. Defendants who violate its terms risk contempt proceedings, not just a new lawsuit. Here, the court made an explicit finding of personal jurisdiction and liability under 35 U.S.C. § 271, meaning the infringement finding is on the public record, even though damages were negotiated.
Binding judicial orderDyson secures injunction and frozen-fund recovery
Dyson achieves its primary enforcement objectives: a permanent injunction prohibiting defendants from selling or importing the infringing product, and recovery of $5,000 from accounts already frozen under the TRO. The court-entered liability finding strengthens Dyson’s position in any future enforcement actions against similar sellers copying the same design. Dyson bears its own legal costs, suggesting the $5,000 recovery is largely symbolic relative to litigation spend.
Permanent injunction grantedDefendants face permanent injunction and account restraints lifted conditionally
Upon Walmart transferring the $5,000 damages amount, defendants’ frozen e-commerce accounts and financial accounts are released from restraint. However, the permanent injunction remains fully in force — defendants are barred from selling the infringing product in any form going forward. The 180-day reinstatement clause creates ongoing exposure: if defendants breach the settlement, Dyson can seek to reopen the case within that window.
Accounts unfrozen on paymentTRO-to-settlement pipeline signals effective deterrence strategy
This case exemplifies Dyson’s mass-enforcement approach against counterfeit and knock-off e-commerce sellers. The rapid resolution — driven by frozen Walmart accounts — suggests the Schedule A / TRO strategy is commercially effective at forcing quick settlements. Other sellers of hair appliance products on U.S. marketplace platforms should treat this as a live signal that Dyson actively monitors and enforces its design patent portfolio with speed and precision.

Official order — verbatim text
The consent judgment is notable for containing an explicit judicial finding of liability under 35 U.S.C. § 271, not merely a settlement recital. This means the court went beyond rubber-stamping a private deal — it made a record finding that defendants infringed D853,642. For Dyson, this creates useful precedent in future enforcement actions. The personal jurisdiction analysis, citing Am. Bridal & Prom, also confirms that operating an interactive e-commerce store shipping to Illinois is sufficient to establish jurisdiction, a point with broad implications for all cross-border marketplace sellers.
USD853,642 — Dyson hair styling and hair care apparatus ornamental design
U.S. Design Patent No. D853,642 (application no. 29/627,749) issued on July 9, 2019, and protects the ornamental design of Dyson’s hair styling and hair care apparatus — widely associated with the Dyson Airwrap or similar premium styling tools. Design patents protect visual appearance rather than functional features, meaning any product that closely resembles the claimed design in the eyes of an ordinary observer may constitute infringement, irrespective of how the product works internally.
D853,642 is strategically significant because Dyson’s hair care product line commands premium retail positioning globally, making it a persistent target for counterfeit and lookalike products on e-commerce platforms. A valid, issued design patent gives Dyson a low-burden enforcement tool: unlike utility patents, design patent infringement does not require claim construction of technical limitations — the visual comparison test is more accessible in motion practice. This makes D853,642 well-suited to the mass-enforcement Schedule A litigation model Dyson is deploying.
Should you run an FTO against USD853,642?
Any company designing, importing, or distributing hair styling appliances — including hair dryers, curling tools, airwrap-style devices, or multi-function styling tools — for sale in the U.S. market should assess their exposure to D853,642. The ordinary observer test for design patents casts a wider net than utility patent claims: a product need not be identical, only substantially similar in overall visual impression. Given Dyson’s demonstrated willingness to pursue marketplace sellers aggressively, a proactive FTO review is commercially prudent before U.S. launch or marketplace listing.
PatSnap Eureka’s FTO Search Agent can map the visual claim scope of D853,642 against your product’s design, identify related Dyson design patent families, and surface prior art that may bear on validity. Eureka can also monitor Dyson’s ongoing filing activity to flag new design applications in the hair care category, giving R&D and product teams early warning of emerging IP barriers before they reach enforcement stage.

Portfolio viewWhat this case signals for the consumer electronics IP enforcement landscape
Dyson’s 73-day enforcement cycle against marketplace sellers illustrates how design patents and TRO procedures combine to create rapid commercial leverage.
Schedule A + TRO is a proven enforcement playbook in N.D. Illinois
The Northern District of Illinois is a favoured venue for brand owners pursuing anonymous e-commerce infringers. The combination of a sealed Schedule A defendant list, a swift ex parte TRO, and Walmart/Amazon account freezes creates asymmetric pressure that drives fast settlements. Dyson’s 73-day close is consistent with this pattern.
Design patent D853,642 remains fully enforceable and actively asserted
The consent judgment confirms that D853,642 survived this enforcement action with no validity challenge raised. Any company sourcing or distributing hair styling apparatus with a design similar to Dyson’s should conduct a freedom-to-operate review against this patent before entering the U.S. market.
Frozen marketplace accounts are the real enforcement lever — not damages
The $5,000 damages figure likely understates Dyson’s litigation cost, suggesting the true enforcement objective is account disruption and injunctive relief, not monetary recovery. Sellers dependent on Walmart or Amazon revenue are structurally vulnerable to this strategy regardless of the merits of the infringement claim.
Reinstatement clause creates 180-day residual exposure for defendants
The dismissal does not immediately convert to a full disposition. Dyson retains the right to reopen the case within 180 days if defendants fail to comply. This is a standard N.D. Illinois mechanism that effectively extends Dyson’s enforcement window and maintains judicial oversight of the settlement terms.
Limited v Partnerships — key questions answered
The case resolved via consent judgment entered November 21, 2024. Three defendants were found liable for infringing Dyson’s design patent D853,642, ordered to pay $5,000 in damages (transferred by Walmart from frozen accounts), and permanently enjoined from selling or importing the infringing product. The case is dismissed with a 180-day reinstatement window.
D853,642, issued July 9, 2019, protects the ornamental design of Dyson’s hair styling and hair care apparatus. Design patents cover visual appearance rather than functional features. In this case, Dyson alleged that defendants’ products sold on Walmart’s marketplace were substantially similar in design to the patented Dyson product, satisfying the ordinary observer infringement test.
Schedule A cases are a mass-enforcement technique where a brand owner sues a large group of anonymous e-commerce sellers on a single complaint, listing defendants on a sealed schedule. The Northern District of Illinois is a preferred venue because courts there have developed efficient procedures for granting ex parte TROs that freeze defendants’ marketplace accounts and funds — creating strong settlement leverage even before defendants are formally served.
The $5,000 figure reflects a negotiated settlement amount rather than a court-assessed damages award. In Schedule A enforcement actions, the primary commercial objective for plaintiffs is typically injunctive relief and account disruption, not maximum monetary recovery from individual low-volume counterfeit sellers. Defendants likely settled quickly to unfreeze their Walmart accounts, accepting a low damages figure in exchange for resolution.
The dismissal in Case No. 1:24-cv-08188 is conditional: the case is dismissed with leave to reinstate within 180 days. If Dyson files a motion to reinstate within that window — for example, if defendants breach the settlement or violate the injunction — the court can reopen proceedings. If no motion is filed within 180 days, the dismissal automatically converts to a dismissal with prejudice, permanently closing the case.
