Shenzhen Deweili v. Alorair Solutions: Design Patent Case Dismissed for Lack of Jurisdiction
Shenzhen Deweili Technology asserted three U.S. design patents covering dehumidifiers, ventilators, and wood dust collectors against Alorair Solutions and four related brands. After 517 days, the Central District of California dismissed the complaint for lack of jurisdiction — without ever reaching the merits of infringement.
Jurisdiction Ends a Multi-Brand Design Patent Fight Over Air Treatment Products
On November 28, 2023, Shenzhen Deweili Technology Co., Ltd., a Chinese manufacturer, filed a patent infringement complaint in the U.S. District Court for the Central District of California (Case No. 5:23-cv-02410). The plaintiff asserted three ornamental design patents — USD0997333S, USD1001256S, and USD0981670S — covering the visual designs of a dehumidifier, a ventilator, and a wood dust collector respectively. Named defendants included Alorair Solutions, Inc. and associated brands Abestorm, BaseAire, Argendon, AlorTec, and Doe defendants.
The case ended on April 28, 2025, when the court dismissed the entire complaint for lack of jurisdiction under Federal Rules of Civil Procedure Rules 12(h)(3) and 58. Prior to final dismissal, defendants Abestorm, BaseAire, Argendon, AlorTec, and Does 1–10 had already been dismissed on or about September 13, 2024, leaving only Alorair Solutions as the remaining active defendant. The court simultaneously denied a motion by the defendant to amend and dismissed the action in full, denying any further requested relief.
The 517-day duration, spanning nearly a year and a half, is notable given that the action never advanced to a merits determination. The jurisdictional dismissal suggests the court identified a fundamental threshold defect — potentially relating to standing, subject matter jurisdiction, or personal jurisdiction over a Chinese plaintiff — that precluded adjudication of the design patent claims. The public record does not disclose whether the plaintiff intends to refile in a different forum or under an amended complaint correcting the jurisdictional deficiency.

Dismissed for lack of jurisdiction: what the ruling means for both parties
Jurisdictional dismissal leaves infringement claims unresolved
Under FRCP Rule 12(h)(3), a federal court must dismiss an action whenever it determines it lacks subject matter jurisdiction. The court here dismissed Shenzhen Deweili’s complaint on that basis — meaning no finding was made on whether Alorair Solutions actually infringed the asserted design patents. A jurisdictional dismissal is not a ruling on the merits, and it does not preclude refiling if the underlying defect can be cured.
No merits adjudicationDeweili loses procedurally — design patent rights remain intact
The dismissal for lack of jurisdiction does not invalidate or weaken Shenzhen Deweili’s three design patents. The patents were never substantively challenged at trial. However, Deweili failed to clear the threshold jurisdictional hurdle, meaning over 517 days of litigation yielded no enforceable judgment. The company may have the option to refile, potentially in a different venue or with corrected pleadings, but any such action would restart the litigation clock.
Patents survive; enforcement stalledAlorair avoids infringement ruling — exposure persists
Alorair Solutions and its associated brands escaped this action without any finding of infringement. However, the dismissal was procedural, not substantive — the court did not rule that Alorair’s products are non-infringing. If Deweili refiles with corrected jurisdictional standing, Alorair faces renewed exposure under the same three design patents. The earlier dismissal of co-brands Abestorm, BaseAire, Argendon, and AlorTec in September 2024 suggests the action was progressively narrowed before its final collapse.
Infringement question unresolvedCross-border design patent enforcement faces jurisdictional headwinds
This case is consistent with a broader pattern of Chinese manufacturers asserting U.S. design patents against domestic competitors, a strategy that has grown sharply in the consumer appliance and air treatment sector. A jurisdictional dismissal here signals that U.S. courts will scrutinise standing and jurisdictional prerequisites rigorously, even when design patents appear formally valid. Companies competing in the dehumidifier and air treatment market should monitor whether Deweili refiles — the underlying design rights remain live and enforceable.

Official order — verbatim text
The court’s order — grounded in FRCP Rules 12(h)(3) and 58 — reflects a finding that the action suffered a jurisdictional defect so fundamental that amendment was unavailable. Notably, the court simultaneously denied the defendant’s motion to amend, suggesting the jurisdictional issue was not attributable solely to the plaintiff’s pleading structure. The explicit denial of ‘any other form of relief’ forecloses any residual claims in this action. Because this was a jurisdictional dismissal rather than a merits ruling, neither party can point to this outcome as precedent on the substantive design patent infringement questions.
USD0997333S, USD1001256S & USD0981670S — Dehumidifier, Ventilator & Dust Collector Designs
The three asserted patents — USD0997333S (App. No. 29/859246), USD1001256S (App. No. 29/862277), and USD0981670S (App. No. 29/858137) — are U.S. design patents protecting the ornamental appearance of consumer air treatment and workshop equipment. Design patents under 35 U.S.C. § 171 protect only the visual, non-functional aspects of a product, and infringement is assessed under the ‘ordinary observer’ test. These patents cover distinct product categories — residential dehumidification, ventilation, and wood dust collection — suggesting a deliberate portfolio approach to locking in the visual identity of Deweili’s product line in the U.S. market.
For competitors in the air treatment and air quality equipment sector, these three patents represent meaningful enforcement risk even following this case’s dismissal. U.S. design patents in consumer appliances are frequently leveraged against Chinese competitors and white-label importers selling visually similar products through e-commerce channels. Any manufacturer or reseller whose dehumidifier, ventilator, or dust collector products share visual similarities with Deweili’s patented designs should assess exposure, particularly given Deweili’s apparent willingness to litigate in U.S. courts across multiple brands simultaneously.
Should you run an FTO against USD0997333S, USD1001256S, and USD0981670S?
If your company manufactures, imports, or retails dehumidifiers, ventilators, or wood dust collectors in the U.S. market, these three Deweili design patents warrant a targeted freedom-to-operate review. The jurisdictional dismissal here resolved nothing about infringement. Any product whose ornamental design is substantially similar to the patented designs — as judged by an ordinary consumer — could attract a refiled or new enforcement action. This risk is amplified for brands selling through Amazon, Walmart, or similar platforms where Chinese patent holders frequently pursue enforcement.
PatSnap Eureka’s FTO Search Agent can map the visual claim scope of USD0997333S, USD1001256S, and USD0981670S against your product portfolio, identify prior art that could support design patent invalidity arguments, and flag related pending applications in Deweili’s design portfolio. For procurement and R&D teams sourcing air treatment products, an early FTO assessment is substantially cheaper than defending a refiled infringement action in the Central District of California.

What this case signals for the air treatment and consumer appliance IP landscape
A jurisdictional dismissal after 517 days highlights how procedural missteps can derail even well-grounded design patent campaigns.
Jurisdictional standing is the first battleground in cross-border design patent suits
Chinese manufacturers asserting U.S. design patents must establish clear jurisdictional hooks before filing in federal court. Deweili’s dismissal under Rule 12(h)(3) — after extensive litigation — illustrates that courts will not overlook foundational defects. IP counsel advising foreign plaintiffs should conduct jurisdictional analysis before complaint drafting, not after.
Design patents on consumer appliances are an active enforcement vector
Three design patents across dehumidifier, ventilator, and wood dust collector form factors signals that Deweili has invested seriously in protecting its product aesthetics in the U.S. market. Competitors selling visually similar air treatment products should treat these patents as live enforcement risks regardless of this case’s outcome, as none were invalidated.
Shenzhen v Alorair — key questions answered
The Central District of California dismissed the case under FRCP Rule 12(h)(3), which requires dismissal when a court lacks subject matter jurisdiction. The court did not articulate the specific jurisdictional defect in the publicly available verdict text, but the dismissal of a Chinese plaintiff’s design patent suit suggests possible issues with standing or Article III jurisdiction. No merits ruling on infringement was issued.
Deweili asserted three U.S. design patents: USD0997333S (App. No. 29/859246), USD1001256S (App. No. 29/862277), and USD0981670S (App. No. 29/858137). These cover the ornamental designs of a dehumidifier, a ventilator, and a wood dust collector respectively. All three patents remain in force and were not invalidated by this case.
A jurisdictional dismissal under FRCP 12(h)(3) is not a ruling on the merits, and does not necessarily preclude refiling. If Deweili can correct the underlying jurisdictional defect — for example by establishing proper standing or subject matter jurisdiction — it could file a new action asserting the same design patents. The public record does not confirm whether the dismissal was with or without prejudice in this specific context.
The case concerned three product categories: dehumidifiers, ventilators, and wood dust collectors. These are consumer and light industrial air treatment and air quality products commonly sold through e-commerce platforms. The defendants — Alorair Solutions, Abestorm, BaseAire, Argendon, and AlorTec — operate in the same product segments.
Defendants Abestorm, BaseAire, Argendon, AlorTec, and Does 1–10 were dismissed from the case on or about September 13, 2024 — approximately 10 months before the final dismissal of the action against Alorair Solutions. The basis for those earlier dismissals is not detailed in the available verdict record, but the progressive narrowing of defendants is consistent with typical multi-brand litigation consolidation or voluntary dismissal of peripheral parties.
