Minimore Living v. Huizhou Jiushengchen Furniture: Sofa Design Patent Dismissed
Minimore Living, Inc. sought a declaratory judgment against Chinese furniture maker Huizhou Jiushengchen Furniture Co., Ltd. over sofa design patent USD1004993S. The Illinois Southern District Court dismissed the case after 187 days, finding it lacked personal jurisdiction over the defendant and that venue was improper — a procedural defeat for the plaintiff before any merits could be reached.
Declaratory judgment bid collapses on jurisdiction and venue
Filed on 25 April 2024 in the Illinois Southern District Court, Minimore Living, Inc. brought a declaratory judgment action against Huizhou Jiushengchen Furniture Co., Ltd., a Chinese furniture manufacturer, concerning sofa design patent USD1004993S (application number US29/865344). The plaintiff sought a court declaration — likely of non-infringement or invalidity — before any infringement suit could be launched against it. Glacier Law LLP represented Minimore Living; no defendant counsel of record was identified, suggesting Huizhou Jiushengchen may not have appeared.
The case closed on 29 October 2024 when Judge John Robert Blakey dismissed the action for lack of personal jurisdiction over Huizhou Jiushengchen and improper venue in the Southern District of Illinois. These are threshold procedural bars: the court found it had no legal basis to compel a Chinese defendant to answer in that forum. No substantive ruling on the validity or infringement of the design patent was issued, leaving those questions legally open.
The 187-day resolution is notably swift and consistent with early-stage procedural dispositions rather than substantive patent litigation. The absence of any defendant law firm on record suggests the dismissal may have been granted on unopposed or default motion practice. What remains unknown is whether Minimore Living intends to refile in a proper venue — such as a district with a stronger nexus to the defendant’s US activities — or whether the threat of patent enforcement by Huizhou Jiushengchen has otherwise dissipated.

Dismissed on jurisdiction and venue: what the ruling means for both sides
Dismissed: no personal jurisdiction and improper venue
A dismissal for lack of personal jurisdiction means the court found it had no authority to bind the defendant — here, a Chinese company — to proceedings in the Southern District of Illinois. Improper venue compounds this: even if jurisdiction existed elsewhere, this district was not the right forum. Critically, neither ground touches the merits of the design patent, so USD1004993S remains legally intact and unchallenged by this proceeding.
Procedural dismissal — no meritsMinimore Living’s declaratory bid fails at the threshold
Minimore Living did not obtain the patent certainty it sought. A declaratory judgment would have allowed it to operate without the threat of infringement claims; instead, that uncertainty persists. The plaintiff may refile in a district where the defendant has sufficient contacts — such as a major e-commerce or import hub — but must first establish a proper jurisdictional hook. The clock on any statute of limitations considerations may also be a factor in any refiling strategy.
Declaratory relief denied — may refileHuizhou Jiushengchen avoids US court scrutiny — for now
The Chinese manufacturer emerged from this action without having to defend the validity or scope of its sofa design patent on the merits. The dismissal is a practical win: the defendant was never subjected to US discovery or injunctive risk in this proceeding. However, the underlying IP dispute is unresolved. If Huizhou Jiushengchen sells into the US market through platforms or distributors, it may face renewed jurisdictional exposure in a court better connected to its commercial activities.
Avoided merits — dispute unresolvedDesign patent disputes with Chinese manufacturers: venue is a real barrier
This case illustrates a structural challenge for US companies seeking preemptive declaratory relief against Chinese design patent holders: establishing personal jurisdiction over an overseas manufacturer with limited US presence is frequently dispositive. Companies in the furniture and home goods sector relying on e-commerce supply chains should assess whether a potential defendant’s US sales activity, platform presence, or distribution arrangements are sufficient to support jurisdiction before commencing declaratory proceedings.

Official order — verbatim text
The dismissal for lack of personal jurisdiction and improper venue is a threshold ruling: Judge Blakey did not evaluate the validity, scope, or infringement of design patent USD1004993S. This means neither party secured a substantive legal advantage on the patent itself. For Minimore Living, the declaratory judgment action failed before it could deliver certainty; for Huizhou Jiushengchen, the patent survives intact but the underlying commercial dispute remains live. The phrasing of the dismissal does not specify whether it was with or without prejudice, though jurisdictional dismissals are typically without prejudice, preserving the plaintiff’s option to refile in an appropriate forum.
USD1004993S — Ornamental sofa design patent (App. No. US29/865344)
USD1004993S is a US design patent protecting the ornamental appearance of a sofa, filed under application number US29/865344. Design patents in the US protect the visual characteristics of a product — its shape, configuration, and surface ornamentation — rather than functional attributes. In the furniture sector, design patents are frequently used to protect distinctive silhouettes and styling elements that differentiate products in competitive retail and e-commerce markets. The patent was the subject of a declaratory judgment action, suggesting Minimore Living faced or anticipated an infringement assertion from the holder.
Design patents for furniture items like sofas have become increasingly significant in cross-border IP enforcement, particularly as Chinese manufacturers expand direct-to-consumer sales through platforms such as Amazon, Wayfair, and Alibaba. A design patent covering a popular sofa form factor can be deployed to challenge competing products with similar ornamental profiles. For US retailers and importers, this case illustrates that even a single design patent held by an overseas manufacturer can create commercial uncertainty that prompts preemptive legal action — and that the effectiveness of that action depends heavily on establishing proper jurisdiction.
Should your product team run an FTO against USD1004993S?
Any company designing, importing, or retailing sofas with ornamental profiles that could overlap with the design claimed in USD1004993S should consider a freedom-to-operate assessment. Because this case ended without a merits ruling, the patent remains fully enforceable. This is particularly relevant for e-commerce furniture brands, contract furniture importers, and OEM buyers sourcing sofa designs from Chinese manufacturers — all of whom could face infringement exposure if their products share ornamental similarity with the protected design.

What this case signals for the furniture design patent IP landscape
Cross-border design patent disputes in furniture hinge on jurisdictional strategy — this case is a cautionary example.
Declaratory judgment plaintiffs must nail jurisdiction before filing
Filing a declaratory judgment action in the wrong forum wastes time and resources without resolving the underlying IP threat. Before commencing such actions against Chinese manufacturers, counsel should map the defendant’s US commercial footprint — including marketplace sales, US-registered agents, and import records — to identify a jurisdictionally sound venue.
Design patent USD1004993S remains unchallenged on the merits
Because the dismissal was purely procedural, the sofa design covered by USD1004993S is still fully enforceable. Competitors and retailers sourcing similar sofa designs should treat this patent as live and conduct freedom-to-operate analysis before commercialising designs with overlapping ornamental features.
Minimore v Huizhou — key questions answered
The case was dismissed because the court found it lacked personal jurisdiction over Huizhou Jiushengchen Furniture Co., Ltd. and that venue in the Southern District of Illinois was improper. No merits ruling on design patent USD1004993S was issued. Jurisdictional dismissals of this type typically leave the plaintiff free to refile in a proper forum.
USD1004993S (application number US29/865344) is a US design patent protecting the ornamental appearance of a sofa. Design patents cover the visual, non-functional characteristics of a product. The patent was the subject of a declaratory judgment action filed by Minimore Living, Inc., suggesting an infringement dispute over sofa design similarity.
A declaratory judgment action allows a party facing a patent threat to proactively ask a court to declare that it does not infringe a patent or that the patent is invalid. In this case, Minimore Living filed such an action to obtain legal certainty regarding USD1004993S before being sued. The action was dismissed on procedural grounds, so no declaration was issued.
A dismissal for lack of personal jurisdiction is generally without prejudice, meaning the plaintiff is not barred from refiling. Minimore Living could potentially bring a new action in a district court where Huizhou Jiushengchen has sufficient contacts — for example, where its products are actively sold or imported into the US market. However, no such refiling is confirmed in the public record.
This case signals that design patent USD1004993S remains active and unchallenged on the merits. Furniture companies sourcing or selling sofa designs with ornamental similarities to the protected design face potential infringement risk. The case also illustrates that establishing personal jurisdiction over Chinese manufacturers in US courts requires evidence of sufficient commercial contacts — a key consideration before pursuing declaratory relief.
