Case Overview
The Parties
⚖️ Plaintiff
Chinese electronics manufacturer asserting U.S. intellectual property rights over its proprietary wireless charger design.
🛡️ Defendants
More than two dozen online marketplace sellers operating storefronts on major e-commerce platforms, accused of infringing Guanyu’s design patent.
The Patent at Issue
This landmark case involved U.S. Design Patent USD892046S covering the ornamental design for a wireless charger, registered with the U.S. Patent and Trademark Office (USPTO). Design patents protect the *visual appearance* of a product, not its function, and offer powerful remedies under 35 U.S.C. § 289.

The Verdict & Legal Analysis
Outcome
The court granted plaintiff’s Motion for Entry of Default and Default Judgment in full, finding all non-appearing defendants in default. The judgment includes:
- • Permanent Injunction prohibiting defendants from using, selling, distributing, or advertising any product bearing the Guanyu Design Patent (USD892046S) or any colorable imitation thereof
- • Damages awarded pursuant to 35 U.S.C. § 289 on a per-defendant basis (specific individual amounts not disclosed in the public order)
- • Asset Freezes requiring third-party payment processors—including PayPal, Alipay, Amazon Pay, Alibaba, Ant Financial, and Wish.com—to restrain and release defendant funds to plaintiff within 14 calendar days
- • Platform Takedowns requiring online marketplace operators including Amazon, eBay, AliExpress, Alibaba, and Dhgate to disable defendant storefronts within seven days of order receipt
Key Legal Issues
Because no defendant appeared, the court did not conduct merits-based claim construction or infringement analysis. Default judgment operates on the legal presumption that well-pleaded allegations are admitted. Guanyu’s complaint established ownership of a valid U.S. design patent and alleged that defendants’ wireless charger products were substantially similar in ornamental appearance—the operative standard under *Egyptian Goddess, Inc. v. Swisa, Inc.*, 543 F.3d 665 (Fed. Cir. 2008), which applies the “ordinary observer” test for design patent infringement. The willfulness finding—implicit in the § 289 damages award and explicit injunctive language—reflects the court’s acceptance of plaintiff’s allegations that defendants intentionally copied the patented design for commercial gain through anonymous online storefronts.

U.S. Design Patent USD892046S (Application No. US29/732794), covering the ornamental design of a wireless charger.
Defendants failed to appear or respond to the complaint. The Northern District of Illinois court granted plaintiff’s unopposed Motion for Entry of Default and Default Judgment, awarding permanent injunctions and damages under 35 U.S.C. § 289.
Under 35 U.S.C. § 289, a design patent infringer is liable for the total profits from the sale of the article of manufacture to which the design is applied. In this case, the default judgment awarded damages under § 289, reinforcing its power in high-volume consumer electronics markets.
