Case Overview
The Parties
⚖️ Plaintiff
Leading global technology brand with a robust IP portfolio covering distinctive product designs in hair care, vacuum, and air purification.
🛡️ Defendant
A collective of over 40 individual e-commerce storefronts operating on major online marketplaces, predominantly overseas-based.
The Patent at Issue
This case centered on Dyson’s U.S. Design Patent No. D715,996, protecting the unique ornamental design of its iconic hair dryer. Design patents are registered with the U.S. Patent and Trademark Office (USPTO) and protect ornamental appearance rather than functional technology.

The Verdict & Legal Analysis
Outcome
The court **granted Dyson’s Motion for Default Judgment in its entirety**, entering a permanent injunction and awarding monetary damages under 35 U.S.C. § 289. Total damages awarded across all defendants exceeded **$256,000**, with major awards including Beilanxi Trading ($168,114) and AFBT ($55,633). The court also ordered third-party payment processors (PayPal, Amazon Pay, Alipay, eBay, Wish.com, DHgate, Walmart, Etsy, and Temu) to freeze and release defendant funds.
Key Legal Issues
The resolution, taking just 60 days, highlights the efficiency of the “file, obtain TRO with asset freeze, serve electronically, and pursue default judgment” model. The Northern District of Illinois continues to be a preferred forum for such e-commerce enforcement. The court’s finding of personal jurisdiction was based on defendants’ interactive storefronts shipping to Illinois. Damages were calculated under 35 U.S.C. § 289 for total profits, with a $250 floor for low-volume sellers, consistent with the Supreme Court’s ruling in Samsung Electronics Co. v. Apple Inc.

U.S. Design Patent No. D715,996, issued October 21, 2014, covering the ornamental design of a Dyson hair dryer.
All defendants failed to appear or answer the complaint. The court accepted Dyson’s allegations as true and entered judgment under Fed. R. Civ. P. 55, supported by screenshot evidence of infringing storefronts.
Any seller offering hair styling products visually similar to Dyson’s patented designs faces significant risk of TRO, asset freeze, and default judgment — even without U.S. physical presence.
