Dyson Technology v. Schedule A Defendants — Design Patent Consent Judgment (116 Days)
Dyson Technology Limited pursued design patent infringement claims against an anonymous e-commerce seller in the Northern District of Illinois, asserting two design patents covering its iconic hair styler and hair dryer aesthetics. The case resolved via consent judgment after 116 days, securing a permanent injunction and $4,000 in damages — a swift enforcement win consistent with Dyson’s broader Schedule A anti-counterfeiting strategy.
Dyson’s Schedule A design patent sweep nets injunction and $4K damages
Dyson Technology Limited filed this action on February 21, 2025, in the U.S. District Court for the Northern District of Illinois against an anonymous defendant (Def. No. 44 operating under seller alias gjnfMMF) identified on a Schedule A, asserting infringement of two U.S. design patents — D852,415 and D853,642 — covering the ornamental designs of its hair stylers and hair dryers. The defendant operated e-commerce stores targeting U.S. consumers, accepted payments in U.S. dollars, and shipped infringing products to Illinois residents.
The case closed on June 17, 2025, through a consent judgment entered by Judge Elaine E. Bucklo. The court found personal jurisdiction, held the defendant liable for patent infringement under 35 U.S.C. § 271, issued a permanent injunction, and ordered Walmart to transfer $4,000 from the defendant’s frozen accounts to Dyson. The case is technically dismissed with leave to reinstate within 180 days, automatically converting to dismissal with prejudice absent a reinstatement motion — a mechanism that preserves Dyson’s enforcement leverage during any payment transition period.
The 116-day resolution reflects the efficiency of Dyson’s enforcement playbook: TRO-based account freezes applied immediately upon filing, placing financial pressure on marketplace sellers to settle early. The $4,000 settlement amount is modest relative to litigation costs but represents a component of a broader multi-defendant campaign — the pattern of Schedule A enforcement is cumulative. What remains undisclosed is the full roster of co-defendants in this action and the aggregate recovery across the campaign.
Filing to Consent Judgment in 116 days
116 days — resolved well within the median Schedule A case timeline in N.D. Illinois
Consent judgment secured: permanent injunction plus $4,000 damages from Walmart account
Consent judgment: court-enforceable resolution by agreement
A consent judgment is a court order that formalises the parties’ negotiated settlement, carrying the same enforceability as a contested judgment. Here, the court made express findings of personal jurisdiction and patent infringement liability before entering the order — giving Dyson a judicially confirmed infringement finding, not merely a private settlement. This matters: the finding under 35 U.S.C. § 271 is on the public record.
Court-entered, fully enforceableDyson secures injunction and account freeze-backed payment
Dyson obtained a permanent injunction barring the defendant from selling, offering, or importing the infringing product and from forming new entities to evade the order. Critically, the court directed Walmart to transfer $4,000 directly from the defendant’s frozen account — a mechanism that ensures payment without relying on voluntary defendant compliance. Dyson bears its own legal costs but achieves market exclusion, the primary objective.
Permanent injunction grantedSeller faces permanent ban and account seizure via Walmart
Defendant gjnfMMF (Def. No. 44) agreed to pay $4,000 in damages and accept a permanent injunction. The consent judgment expressly bars creating successor entities to circumvent the order. The case is technically dismissed with leave to reinstate for 180 days — meaning Dyson retains the right to return to court if the defendant re-emerges or fails to comply. Walmart account restraints lift only upon confirmed payment transfer.
Enjoined; account restrainedSchedule A enforcement: cumulative pressure on marketplace counterfeiters
This case is one data point in Dyson’s broader Schedule A enforcement campaign targeting e-commerce design infringers across major U.S. marketplaces. The TRO-plus-account-freeze model is engineered for leverage: sellers face operational disruption from day one, making early settlement economically rational. Competitors and marketplace sellers in the personal care appliance space should note that Dyson actively monitors and enforces its design patent portfolio with speed and consistency.

Official order — verbatim text
The consent judgment is notable for its explicit judicial findings prior to the agreed order — the court affirmatively found personal jurisdiction and infringement liability under 35 U.S.C. § 271 rather than simply endorsing a private settlement. This distinction means the infringement finding carries judicial authority. The permanent injunction’s anti-circumvention language, expressly barring successor entities, reflects N.D. Illinois practice in Schedule A cases and extends Dyson’s enforcement reach beyond the named defendant alias.
USD0852415S & USD0853642S — Dyson hair appliance ornamental designs
U.S. Design Patents D852,415 (issued June 25, 2019) and D853,642 (issued July 9, 2019) protect the ornamental visual appearance of Dyson’s hair styling and drying appliances — not their functional mechanics. Both filed under application numbers US29/627707 and US29/627749 respectively, these design patents cover the specific aesthetic elements that give Dyson products their distinctive commercial identity. Design patents grant 15-year terms from grant date under U.S. law, placing both patents within their active enforcement window through 2034.
For Dyson, design patents serve a dual function: brand protection and competitive moat. The distinctive visual language of Dyson hair appliances commands premium retail positioning, and lookalike products on e-commerce platforms directly threaten that brand equity. Because the ordinary observer test — rather than a claim-by-claim technical comparison — governs design patent infringement, enforcement is faster and the infringement standard more intuitive to courts. This makes design patents particularly effective enforcement instruments against marketplace counterfeiters and copycat OEM products entering U.S. channels.
Should you run an FTO against USD0852415S and USD0853642S?
Any company developing or sourcing hair appliances — dryers, stylers, straighteners, or multi-function tools — that will be sold on U.S. e-commerce platforms (Amazon, Walmart, Temu, Shein) should conduct a design patent freedom-to-operate analysis against Dyson’s active design patent portfolio. This case confirms Dyson actively monitors marketplace listings and moves swiftly: TROs were secured and account freezes applied before the seller could respond. The risk is not hypothetical — it is operational and immediate.
PatSnap Eureka’s FTO Search Agent can map your product’s visual design against Dyson’s design patent claims, identify the closest prior art, and flag design-around opportunities before your product reaches U.S. customs or marketplace listing. Eureka surfaces the full Dyson design patent family, prosecution history, and related enforcement actions — giving your IP and product teams the intelligence to make a launch decision with confidence rather than exposure.

Portfolio viewWhat this case signals for the consumer electronics IP enforcement landscape
Dyson’s Schedule A strategy demonstrates how design patents function as rapid-deployment enforcement tools against e-commerce infringers.
TRO-based account freezes are the real enforcement lever in Schedule A cases
Dyson’s ability to freeze defendant Walmart accounts at the TRO stage — before any merits ruling — is what drives early settlement. The $4,000 damages figure reflects the leverage of operational disruption, not the full value of infringing sales. Marketplace sellers should treat TRO risk as an existential prompt to audit their product listings against active design patent portfolios.
Consent judgment preserves an infringement finding — stronger than a settlement alone
By obtaining a court-entered finding of infringement under 35 U.S.C. § 271, Dyson builds a public enforcement record. This matters in future actions: a pattern of consent judgments can support enhanced damages arguments and signals to other potential infringers that Dyson litigates to enforceable conclusions, not just private releases.
Design patent scope for Dyson’s D852,415 and D853,642 — freedom-to-operate risk zones
The ornamental design claims in D852,415 and D853,642 cover specific visual elements of Dyson hair appliances. Products with similar silhouette, handle geometry, or airflow nozzle styling may fall within the ordinary observer test — even if functionally different. Any competitor or private-label seller in the personal care appliance space should run a formal design patent FTO before launching similar-looking products in U.S. marketplaces.
The 180-day reinstatement window creates a rolling enforcement option for Dyson
The dismissal-with-leave-to-reinstate structure is a deliberate Dyson enforcement tool. If defendant gjnfMMF resurfaces under a new seller alias or fails to comply, Dyson can reinstate without refiling — saving time and cost. IP teams monitoring Dyson’s enforcement activity should track whether reinstatement motions are filed as indicators of defendant non-compliance or recidivism.
Limited v Partnerships — key questions answered
Dyson asserted U.S. Design Patent Nos. D852,415 and D853,642, both covering the ornamental designs of its hair styler and hair dryer products. D852,415 issued June 25, 2019, and D853,642 issued July 9, 2019.
The case resolved via a consent judgment entered June 17, 2025. The court found the defendant liable for patent infringement under 35 U.S.C. § 271, issued a permanent injunction, and ordered Walmart to transfer $4,000 from the defendant’s frozen account to Dyson. The case is dismissed with leave to reinstate within 180 days.
Dyson obtained a Temporary Restraining Order early in the case that restrained the defendant’s Walmart e-commerce store and financial accounts. The consent judgment then directed Walmart to transfer $4,000 directly from the defendant’s frozen account to Dyson, ensuring payment without relying on voluntary defendant compliance.
The permanent injunction bars the defendant, its agents, employees, and any associated parties from offering for sale, selling, or importing the infringing products. It also explicitly prohibits forming new entities or using other devices to circumvent the injunction — a standard anti-evasion clause in N.D. Illinois Schedule A cases.
A Schedule A lawsuit is a multi-defendant enforcement action where the plaintiff files against a list of anonymous defendants — typically e-commerce sellers identified by alias — as a single case. Dyson uses this structure to pursue multiple marketplace infringers simultaneously, securing TROs that freeze accounts before defendants can liquidate assets or remove listings, creating strong early settlement pressure.
