Socket Solutions v. Yuyao Zhuoli: Default Judgment & Permanent Injunction in 110 Days
Socket Solutions, LLC secured a permanent injunction and full default judgment against Chinese manufacturer Yuyao Zhuoli Wire Cable Factory for infringing two outlet cover patents and falsely passing off products as genuine Sleek Socket® goods. The case resolved in just 110 days — the defendant never appeared in court.
Swift default judgment in the electrical safety accessory IP space
Socket Solutions, LLC filed suit on November 2, 2023, in the U.S. District Court for the Northern District of Illinois against Yuyao Zhuoli Wire Cable Factory, a Chinese wire and cable manufacturer. The complaint alleged direct and induced infringement of U.S. Patent No. 9,509,080 (the ‘080 Patent) via single-cord wall outlet covers, and direct infringement of U.S. Patent No. 11,450,997 (the ‘997 Patent) via dual-cord outlet covers, both sold through Alibaba.com into the U.S. market. Socket Solutions also alleged Lanham Act violations for false safety certification markings and counterfeit Sleek Socket® branding.
Because Zhuoli never appeared, answered, or sought an extension, the court entered a default on December 27, 2023, and on February 20, 2024, issued a comprehensive judgment and permanent injunction. The injunction bars Zhuoli, its affiliates, officers, agents, and anyone acting in concert with them from manufacturing, selling, offering to sell, or importing the infringing outlet covers into the United States — covering products not more than colorably different from those at issue. The Lanham Act finding additionally prohibits Zhuoli from representing to any customer that it sells genuine Sleek Socket® products.
The 110-day timeline is consistent with default proceedings where a foreign defendant declines to engage with U.S. process. No contested merits briefing occurred, so the court’s infringement findings rest on Socket Solutions’ uncontested allegations and the complaint record. What remains unknown from the public docket is whether any damages were separately awarded or if enforcement proceedings have been initiated to block Zhuoli’s Alibaba storefronts — issues that frequently arise after cross-border default injunctions of this kind.

What a default judgment means — and its limits
A default judgment is entered when a defendant fails to appear or respond. The court accepts the plaintiff’s well-pleaded allegations as true and enters judgment without a contested merits trial. Here, Zhuoli’s non-appearance led to an uncontested finding of infringement on both patents. Importantly, the judgment is as legally binding as a litigated one — but enforcing it against a China-based entity involves distinct practical challenges.
Uncontested liability findingPermanent injunction: scope and enforceability
The permanent injunction covers not just the named products but any outlet cover ‘not more than colorably different’ — a deliberately broad formulation that captures design-arounds. It binds Zhuoli’s parents, subsidiaries, officers, agents, and those acting in concert. Cross-border enforcement typically requires separate action: U.S. Customs recordation, ITC exclusion orders, or platform takedowns are common follow-on steps not visible in this docket.
Broad product scopeFalse advertising and counterfeit branding compounds liability
Beyond patent infringement, the court found Zhuoli violated Section 43(a) of the Lanham Act by affixing false safety certifications, claiming ‘Enhanced Safety,’ and falsely representing products as genuine Sleek Socket® goods. This dual-track liability — patent plus trade dress/false advertising — is a common enforcement strategy against overseas counterfeiters, and can support additional remedies including damages and platform-level enforcement.
Lanham Act § 43(a) violationEnforcing a U.S. judgment against a Chinese manufacturer
China does not automatically recognise or enforce U.S. civil judgments. Practical enforcement of this injunction is likely to rely on U.S. Customs recordation of the patents, e-commerce platform takedown requests directed at Alibaba, and potentially a Section 337 ITC complaint if infringing imports persist. The Alibaba.com sales channel identified in the complaint gives Socket Solutions a concrete platform enforcement avenue without requiring cooperation from Zhuoli.

Stipulation of dismissal — official text
The court’s February 20, 2024 order constitutes a comprehensive default judgment covering infringement of both patents under 35 U.S.C. §§ 271(a) and 271(b), a Lanham Act § 43(a) false advertising violation, and a permanent injunction of unusually broad scope. The ‘not more than colorably different’ language in the injunction is significant: it prevents Zhuoli from evading compliance through minor product modifications. Because the judgment was entered on default, Zhuoli retains a theoretical right to move to vacate under Fed. R. Civ. P. 60(b), though no such motion appears on the docket.
US9509080B1 & US11450997B1 — Wall Outlet Cover Patents
U.S. Patent No. 9,509,080 (App. No. 15/099,559) and U.S. Patent No. 11,450,997 (App. No. 17/175,604) both protect wall outlet cover designs associated with the Sleek Socket® product line. The ‘080 Patent covers single-cord outlet configurations, with Claim 19 at issue in this litigation. The ‘997 Patent, a more recent grant filed in 2021, covers dual-cord outlet cover configurations with Claim 1 asserted. Both patents are in the consumer electrical safety accessory space — a sector where product differentiation is closely tied to patented form factors and safety-certification marks.
The strategic value of these patents lies in their coverage of a consumer safety product sold through mainstream e-commerce channels. The ‘080 and ‘997 Patents together create complementary protection for single- and dual-cord product formats, limiting a competitor’s ability to design around one grant without potentially infringing the other. The Alibaba.com sales channel targeted in this case is consistent with broader patterns of Chinese manufacturers exporting commodity electrical accessories into the U.S. market — a recurring enforcement challenge for domestic IP holders in this category.
Should you run an FTO analysis against US9509080B1 and US11450997B1?
Any company designing, manufacturing, or importing wall outlet covers — particularly flush-fit or cord-management configurations — into the U.S. market should treat these patents as active freedom-to-operate risks. The ‘080 and ‘997 Patents cover both single-cord and dual-cord variants, and the injunction language in this case extends to products ‘not more than colorably different.’ That means incremental design changes may not provide safe harbour. E-commerce sellers listing outlet covers on U.S.-facing platforms, including Alibaba, Amazon, or direct DTC channels, face particular exposure given this enforcement precedent.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the claim sets of both patents, flagging overlap at the claim element level and surfacing prior art that may be relevant to validity challenges. If you are actively marketing outlet cover products, setting up a claim monitoring alert for the Socket Solutions portfolio — including any continuation or divisional applications — will provide early warning of scope expansion before new grants issue.

What this case signals for the electrical accessories IP enforcement landscape
This case illustrates a targeted, fast-track enforcement model that U.S. patent holders are increasingly deploying against Chinese e-commerce sellers.
Default judgment is a viable fast-track tool against non-appearing Chinese sellers
When a Chinese manufacturer sells infringing products through Alibaba or similar platforms but lacks U.S. operations, it may not engage with U.S. litigation. Socket Solutions obtained a permanent injunction in under four months by filing a well-documented complaint, securing email service, and moving efficiently to default. This model is replicable for other IP holders facing similar cross-border infringement.
Combining patent and Lanham Act claims strengthens e-commerce enforcement leverage
The addition of Lanham Act false advertising and counterfeit branding claims alongside patent infringement significantly widens the injunction’s practical scope. Platform operators like Alibaba and Amazon are more responsive to takedown requests that cite both IP infringement and counterfeit brand claims simultaneously. Companies holding patents on consumer safety products should audit whether competitor listings also trigger false certification or branding violations.
Socket v Yuyao — key questions answered
Socket Solutions asserted U.S. Patent No. 9,509,080 (covering single-cord wall outlet covers, Claim 19) and U.S. Patent No. 11,450,997 (covering dual-cord wall outlet covers, Claim 1). Both patents were found valid and enforceable in the February 20, 2024 default judgment.
Defendant Yuyao Zhuoli Wire Cable Factory never appeared, responded to the complaint, or sought an extension after being served by email on November 8, 2023. The court entered a default on December 27, 2023, and subsequently granted a permanent injunction and full judgment on February 20, 2024.
The injunction bars Zhuoli, its affiliates, officers, and agents from manufacturing, selling, offering to sell, or importing the infringing single-cord and dual-cord outlet covers into the U.S., inducing others to do so, and representing to customers that it sells genuine Sleek Socket® products. It covers products ‘not more than colorably different’ from the infringing items.
The court found Zhuoli violated Section 43(a) of the Lanham Act by including false and misleading safety certification markings on its outlet covers, making false ‘Enhanced Safety’ promotional claims, and falsely representing to customers that it sold genuine Sleek Socket® branded products.
Because China does not automatically recognise U.S. civil judgments, enforcement typically requires recording the patent with U.S. Customs and Border Protection, requesting takedowns directly with e-commerce platforms such as Alibaba, and potentially filing a Section 337 complaint with the U.S. International Trade Commission to seek an exclusion order blocking infringing imports.
