Dyson Technology Ltd v. Schedule A Defendants: Design Patent Dispute Closed in 13 Days
Dyson Technology Limited filed suit in the Northern District of Illinois against an anonymous group of online sellers, asserting two design patents covering hair styling and hair care apparatus. The case resolved in just 13 days when Dyson voluntarily dismissed its claims against Yiwu Xunhan Trading Co., Ltd. without prejudice — leaving the door open for future enforcement.
Dyson’s rapid-exit Schedule A enforcement action in N.D. Illinois
On August 22, 2025, Dyson Technology Limited filed a design patent infringement action in the Northern District of Illinois (Case No. 1:25-cv-10068) before Judge Lindsay C. Jenkins. The complaint named ‘The Partnerships and Unincorporated Associations Identified on Schedule A’ — a standard enforcement vehicle used in e-commerce IP actions — and asserted two design patents, USD852415S and USD853642S, both covering hair styling and hair care apparatus. Greer, Burns & Crain, Ltd. represented Dyson.
The case closed on September 4, 2025 — just 13 days after filing — when Dyson filed a voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1). The dismissal was without prejudice and targeted specifically Yiwu Xunhan Trading Co., Ltd. and associated individuals and entities. A without-prejudice dismissal means Dyson has not relinquished its substantive claims and may refile against this defendant in future proceedings.
The 13-day resolution is consistent with the swift lifecycle of many Schedule A cases in N.D. Illinois, where plaintiffs often obtain a temporary restraining order to freeze marketplace assets before defendants are formally served, and then dismiss once a settlement or asset recovery is achieved. The public record does not disclose whether any financial settlement or asset transfer accompanied this dismissal, so the commercial outcome for Dyson remains unknown from available filings.

13 days — well below the median lifespan for Schedule A design patent cases in N.D. Ill.
Dismissed without prejudice: what Dyson’s exit filing means for both sides
Rule 41(a)(1): plaintiff-controlled dismissal, no court approval needed
A dismissal under Federal Rule of Civil Procedure 41(a)(1) can be filed by the plaintiff as of right before the defendant serves an answer or motion for summary judgment. It requires no judicial approval and takes effect immediately upon filing. Because no defendant counsel appeared in this case, Dyson had unilateral authority to exit the litigation on its own timeline.
Procedural exit, no merits rulingDyson keeps its claims alive — refiling remains an option
A without-prejudice dismissal expressly preserves Dyson’s right to refile the same claims against Yiwu Xunhan Trading Co., Ltd. in the future. This contrasts with a with-prejudice dismissal, which would permanently bar those claims. The public record does not disclose whether a settlement was reached; if compensation or marketplace removal was obtained privately, a without-prejudice structure may still have been chosen to preserve ongoing enforcement leverage.
Claims preserved, future filing possibleNo injunction, no judgment — but exposure remains
Yiwu Xunhan Trading Co., Ltd. faces no court-ordered injunction or damages award from this action. However, the without-prejudice dismissal means the defendant has not achieved a clean legal win. If any marketplace account freezes were obtained via a temporary restraining order prior to dismissal, their status depends on separate court orders and is not addressed by the dismissal filing itself.
No judgment, ongoing exposure riskDyson’s Schedule A strategy: fast pressure, quiet resolution
This case is consistent with Dyson’s broader use of Schedule A litigation as a rapid-enforcement tool against online counterfeiters and design copycats in the hair care appliance sector. The 13-day lifecycle suggests the filing achieved its commercial objective — whether through asset freezing, marketplace takedown, or private settlement — without requiring prolonged litigation. Design patents on product appearance remain a powerful lever against e-commerce infringement.

Official order — verbatim text
Dyson’s Rule 41(a)(1) filing named Yiwu Xunhan Trading Co., Ltd. specifically, suggesting the company was identified as the primary target from among the broader Schedule A roster. The without-prejudice qualifier is the operative legal term: it prevents claim preclusion and keeps Dyson’s enforcement options fully intact. No court reviewed the merits of the design patent infringement allegations, so neither the validity of USD852415S and USD853642S nor the question of infringement was adjudicated.
USD852415S & USD853642S — Hair Styling Apparatus Design Patents
USD852415S (App. No. US29/627707) and USD853642S (App. No. US29/627749) are U.S. design patents protecting the ornamental appearance of Dyson’s hair styling and hair care products. Design patents cover the way a product looks rather than how it works, making them particularly effective against copycat products that replicate Dyson’s distinctive aesthetic. The close application numbers suggest the two patents were filed as a coordinated pair, likely capturing related design variations of the same product family.
For Dyson, these design patents serve as a frontline defence of the premium visual identity that differentiates its hair care products — such as the Airwrap and Supersonic — from lower-cost alternatives flooding online marketplaces. In the consumer appliance sector, ornamental design protection is increasingly critical because functional features may be difficult to patent once a technology becomes commoditised. Competitors and OEM manufacturers developing hair styling tools should treat Dyson’s design patent portfolio as a live enforcement risk, particularly when targeting international e-commerce channels.
Should you run an FTO against USD852415S and USD853642S?
Any company designing, manufacturing, or distributing hair styling or hair care apparatus for sale on global online marketplaces — particularly Amazon, Walmart, or eBay — should assess freedom-to-operate against Dyson’s design patent family. The risk is not limited to direct copycats: design patent infringement is assessed by whether an ordinary observer would find the designs substantially similar, a standard that can capture products with only a superficial resemblance to Dyson’s registered aesthetic.
PatSnap Eureka’s FTO Search Agent can map the ornamental claim scope of USD852415S and USD853642S against your product’s design drawings, flag prosecution history that may inform design-around strategies, and identify related Dyson design filings in international jurisdictions. For product teams preparing a market entry in the hair care appliance category, an Eureka-powered FTO review can surface risk before tooling and inventory investment is committed.

What this case signals for the hair care appliance IP landscape
Dyson’s rapid Schedule A filing and exit illustrates how design patent enforcement is weaponised against e-commerce sellers in consumer electronics.
Schedule A filings create immediate commercial pressure before trial
N.D. Illinois courts routinely grant TROs and asset freezes in Schedule A actions within days of filing. For online sellers of hair styling products, this means account suspension and payment holds can precede any meaningful opportunity to respond. Brand owners in the consumer appliance sector should monitor this channel for competitive intelligence.
Design patents are Dyson’s sharpest enforcement tool in hair care
USD852415S and USD853642S protect the ornamental appearance of Dyson’s hair styling apparatus — a scope that can be difficult to design around for low-cost manufacturers aiming to replicate the premium aesthetic. Companies in adjacent product categories should assess whether their product design overlaps with Dyson’s registered design portfolio before entering the market.
Limited v Partnerships — key questions answered
Dyson asserted two U.S. design patents: USD852415S (App. No. US29/627707) and USD853642S (App. No. US29/627749), both covering the ornamental design of hair styling and hair care apparatus.
The case was dismissed just 13 days after filing via a Rule 41(a)(1) voluntary dismissal. This timeline is consistent with Schedule A litigation strategy, where plaintiffs often obtain a TRO to freeze marketplace assets and then dismiss once enforcement objectives are achieved — though the public record does not confirm whether a settlement was reached.
A without-prejudice dismissal means Dyson’s infringement claims were not adjudicated on the merits and Dyson retains the right to refile the same claims against Yiwu Xunhan Trading Co., Ltd. in the future. The defendant received no court-ordered judgment but also has no clean legal victory to rely on.
USD852415S and USD853642S are U.S. design patents protecting the ornamental appearance of Dyson’s hair styling and hair care apparatus. Design patents cover how a product looks rather than how it functions, and infringement is assessed by whether an ordinary observer would consider the accused design substantially similar to the patented design.
A Schedule A filing is a litigation strategy used primarily in N.D. Illinois where a plaintiff names multiple anonymous defendants — typically online marketplace sellers — on a confidential schedule filed with the court. It allows plaintiffs to obtain emergency relief such as TROs and asset freezes against numerous sellers simultaneously before identifying them publicly.
