The Patent at Issue
This landmark case involved U.S. Design Patent No. USD938,242S (U.S. Application No. 29/730,088) covering the ornamental design of a key chain with a door opening hook and stylus. 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
Judge Andrea R. Wood granted Plaintiff’s Motion for Entry of Default and Default Judgment in its entirety. All named defaulting defendants were deemed in default. The court entered a permanent injunction and awarded monetary damages in the form of disgorgement of profits under 35 U.S.C. § 289, attracting broad attention from IP professionals and e-commerce companies worldwide.
The aggregate damages reflect individualized profit calculations per defendant seller, consistent with § 289’s requirement that infringers disgorge total profits from the sale of infringing articles — a powerful remedy unique to design patent law with no analogous cap. For example, LML Metal Product Ltd. was liable for $26,729, Guangzhou Tianhui Hardware Co., Limited for $9,093, and multiple smaller defendants for $250 each.
Key Legal Issues
The case proceeded on a default basis, meaning the court accepted the plaintiff’s well-pleaded allegations as true under Fed. R. Civ. P. 55. The absence of any defense response eliminated the need for claim construction hearings, validity challenges, or infringement analysis at trial. The legal standard applied for design patent infringement is the ordinary observer test established in Egyptian Goddess, Inc. v. Swisa, Inc., 543 F.3d 665 (Fed. Cir. 2008). The application of 35 U.S.C. § 289 — which entitles design patent holders to an infringer’s total profits from the article of manufacture — is particularly significant. Unlike utility patent damages under § 284, § 289 does not require apportionment. This makes design patents disproportionately powerful enforcement tools for consumer product companies.

The case involved U.S. Design Patent No. USD938,242S (Application No. 29/730,088), covering the ornamental design of a key chain with a door opening hook and stylus.
Section 289 entitles design patent holders to recover an infringer’s total profits from the sale of any article bearing the infringing design, without apportionment — a remedy exclusive to design patent law.
Sellers of key chains and related accessories on U.S.-accessible platforms should conduct immediate design patent clearance. Platform-level asset freezes mean infringement exposure can result in account and fund restrictions before a seller is even aware of litigation.
