26-cv-12807 | Dyson Files Suit: Hair Dryer, Styler, and Vacuum Accessory Sellers Take Note

Case overview

• Plaintiff: Dyson Technology Limited (a Dyson group company)
• Court: U.S. District Court for the Northern District of Illinois
• Filed: October 19, 2026
• Status: Filed. The plaintiff also filed a “Leave to File” document the same day, which in Schedule A cases usually seeks leave to file the defendant list and other materials under seal.

The complaint and Schedule A defendant list are not yet public; the rights and products at issue will be updated.

What may happen next

Schedule A plaintiffs usually move for a TRO within days of filing. Once granted, marketplaces freeze defendants’ funds. If your store is frozen in the coming days and your products relate to this brand, this case is a likely source.

Seller checklist

Dyson enforcement may involve trademarks, design patents, or utility patents; the complaint will tell. We suggest:

• Check for products that look like Dyson hair dryers, stylers, vacuums, or fans
• For compatible accessories (filters, heads, batteries) using “for Dyson,” make clear they are compatible items and avoid Dyson logos or official images
• Check whether images or descriptions imply an affiliation with Dyson

Already frozen?

Keep the platform notice, emails from plaintiff’s counsel, affected listings, and sales records. Hold off on replying to the plaintiff or signing anything, and have counsel review the case. See our guide: Store Frozen by a TRO: The First 72 Hours.
