Dyson Wins Design Patent Case Against Counterfeit Hair Styler Sellers

Case Overview

The Parties

The Patents at Issue

This case involved two design patents protecting Dyson’s distinctive hair care product designs:

• • USD852,415S — Ornamental appearance of a Dyson hair styling device
• • USD853,642S — Ornamental appearance of a related hair care product design configuration

Design patents protect the novel, ornamental appearance of a functional article — not its underlying mechanics. Under Egyptian Goddess, Inc. v. Swisa, Inc. (Fed. Cir. 2008), infringement is assessed through the “ordinary observer” test: whether an ordinary purchaser would mistake the accused product for the patented design.

The Accused Products

The alleged infringing products were counterfeit or unauthorized replicas of Dyson hair stylers and hair dryers, specifically those marketed through online retail channels that copied the distinctive visual design of Dyson’s premium devices.

Legal Representation

Dyson retained Greer, Burns & Crain, Ltd. (Chicago, IL), a law firm with recognized expertise in IP enforcement and Schedule A e-commerce litigation. Attorneys of record included Andrew Daniel Burnham, Justin R. Gaudio, Justin Tyler Joseph, and Lawrence J. Crain. No defense counsel appeared on the docket, consistent with default posture in Schedule A actions.

The Verdict & Legal Analysis

Outcome

The case was terminated with an order directing the release of Dyson’s $10,000 bond — the security posted to obtain preliminary injunctive relief — back to Dyson or its counsel. Bond release upon case termination indicates the injunctive relief phase concluded and the matter resolved in Dyson’s favor, with no need for continued security.

Litigation Timeline & Procedural History

The case was filed on **January 7, 2025**, and closed on **April 1, 2025**, totaling just 84 days. This rapid resolution strongly indicates a standard Schedule A workflow: ex parte temporary restraining order (TRO) to freeze defendant assets and storefronts, followed by preliminary injunction, and ultimately a default judgment or negotiated resolution before trial.

The Illinois Northern District Court is a preferred forum for Schedule A enforcement actions due to procedural familiarity with ex parte TRO applications. Chief Judge John Robert Blakey presided over this matter, providing experienced judicial oversight.

Legal Significance

This case reinforces several important legal principles:

• Design Patent Enforcement Velocity: Design patents offer faster, lower-burden infringement proof than utility patents; visual comparison governs.
• Schedule A Procedural Efficacy: The 84-day lifecycle demonstrates that Schedule A proceedings provide efficient IP enforcement against e-commerce counterfeiters.
• Bond Release as Litigation Signal: The $10,000 bond release confirms Dyson did not overreach in seeking injunctive relief.

Strategic Takeaways

• For Patent Holders: Pair utility patents with design patents for comprehensive product protection. Design patents are powerful against counterfeiters due to visually obvious copying.
• For Accused Infringers: In Schedule A actions, failing to appear is commercially catastrophic. Engage counsel early to negotiate asset unfreezes or challenge TRO scope.

Industry & Competitive Implications

The personal care appliance market—valued at over $50 billion globally—has become a primary battleground for design patent enforcement. Dyson’s premium positioning makes it a frequent target for counterfeit operations, particularly on cross-border e-commerce platforms where enforcement asymmetry historically favored bad actors.

This case reflects a broader industry trend toward systematic Schedule A enforcement programs adopted by premium brands. Rather than filing individual suits, these brands maintain rolling enforcement dockets against hundreds of anonymous sellers per year, using initial TROs to disrupt supply chains.

For competitors in the personal care space, this case underscores that Dyson actively monitors and enforces its design IP portfolio. Companies developing hair styling tools should budget for comprehensive design patent clearance searches and consider filing defensive design patent applications on distinctive product features before market launch.
