Jinhuanshi v. Dbest Products: Stackable Storage Bin Patent Case Dismissed in 62 Days
Chinese e-commerce seller Jinhuanshi (trading as Hhuohuachichi) filed a patent infringement action against Dbest Products Inc. in the Illinois Northern District Court, asserting US12103576B2 over stackable storage bins sold on Amazon. The case was voluntarily dismissed without prejudice just 62 days after filing, before any merits ruling was reached.
Amazon storage bin patent dispute ends before first hearing
On 27 December 2024, Jinhuanshi Electronic Commerce Co., Ltd. — operating under the brand name Hhuohuachichi — filed suit in the U.S. District Court for the Northern District of Illinois against Dbest Products Inc., a consumer storage products company. The complaint asserted infringement of US12103576B2, a patent covering stackable storage bins, against five Dbest product listings on Amazon (ASINs B0CGD1R87W, B0DGTP4PZJ, B0CGD1W4P6, B0D93RMSVD, and B0D9BCZJSK) and products sold through dbest-products.com.
On 27 February 2025 — exactly two months after filing — plaintiff’s counsel filed a notice of voluntary dismissal without prejudice pursuant to Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure. Because Dbest had not yet filed an answer or a motion for summary judgment at the time of the notice, dismissal was effective automatically upon filing, requiring no court order. The filing also requested that an in-person hearing scheduled for 28 February 2025 be stricken as moot, confirming the case terminated the day before that hearing.
The 62-day lifespan is notably brief even for voluntary dismissals, and the timing — filed the day before a scheduled court hearing — is consistent with a pre-hearing resolution or strategic withdrawal. The public record does not disclose whether a settlement was reached, a licensing arrangement was agreed, or the plaintiff simply elected to abandon the action. Because the dismissal is without prejudice, Jinhuanshi retains the right to re-file claims against Dbest on the same patent, subject to applicable statutes of limitations.

62 days — resolved well below the median district court patent case lifespan
Voluntarily dismissed: what the Rule 41 notice means for both parties
Rule 41(a)(1)(A)(i): automatic dismissal, no court order needed
Under Rule 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. Dismissal is immediate and self-executing. Because Dbest had not yet answered, Jinhuanshi could exit the case unilaterally. No judge signature was required, and no merits determination was made.
Procedural exit — no merits rulingWithout prejudice: the public record does not confirm finality
A dismissal ‘without prejudice’ preserves the plaintiff’s right to re-file the same claims. A dismissal ‘with prejudice’ would bar re-filing permanently. The notice here expressly states ‘without prejudice,’ meaning Jinhuanshi can reassert US12103576B2 against Dbest in a future action. Whether a private settlement or license underlies this exit is not disclosed in the public docket — the record is silent on any commercial terms.
Re-filing right preservedDbest escapes a merits ruling — but patent risk persists
Dbest Products Inc. faces no adverse judgment and incurs no liability from this termination. However, the without-prejudice nature of the dismissal means the threat of re-litigation under US12103576B2 remains live. Dbest may wish to consider whether its stackable storage bin product line requires design modification, a freedom-to-operate clearance, or an IPR challenge against the asserted patent to secure long-term certainty.
No liability — risk not extinguishedAmazon storage product sellers face recurring assertion risk
This case is consistent with a pattern of short-cycle patent assertions targeting Amazon ASIN-level product listings by Chinese IP holders. The rapid filing and equally rapid withdrawal suggests either a licensing negotiation concluded off-docket, or the plaintiff is managing a broader enforcement campaign. Competing sellers of stackable storage bins should monitor US12103576B2 and assess whether their own product lines fall within its claims.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly states ‘without prejudice,’ meaning no merits determination was made and no preclusive effect attaches. The phrasing confirms Dbest had not yet answered, enabling unilateral plaintiff withdrawal. The simultaneous request to strike the 28 February hearing as moot is procedurally routine but confirms the case ended the day before substantive proceedings would have commenced. No findings on infringement, validity, or damages were entered.
US12103576B2 — stackable storage bin structure and design
US12103576B2, filed under application number US18/542495, covers stackable storage bin technology — a product category with high velocity in the e-commerce and home organisation market. The patent’s corrected application number suggests it progressed through the USPTO’s standard examination pathway. Stackable storage patents in this space typically protect the interlocking geometry, structural load-bearing features, or modular connectivity mechanisms that distinguish one product from commodity alternatives.
For the consumer storage and home organisation sector, utility or design patents on stackable bin systems represent meaningful competitive moats, particularly when enforced against Amazon marketplace sellers. Jinhuanshi’s willingness to file in a U.S. federal court suggests the patent holder views US12103576B2 as commercially viable for licensing or enforcement. Competing manufacturers — including private-label sellers and Amazon FBA operators — should assess whether their modular storage products read on the claims of this patent before scaling inventory.
Should you run an FTO analysis against US12103576B2?
Any company manufacturing, importing, or selling stackable storage bins in the U.S. market — particularly via Amazon — should treat US12103576B2 as an active enforcement risk. This case demonstrates the patent holder is prepared to file federal infringement actions. The without-prejudice dismissal means re-filing is possible at any time. Product teams developing new modular storage SKUs should request an FTO clearance before launch, especially if the design involves interlocking or stacking geometry similar to Dbest’s product range.
PatSnap Eureka’s FTO Search Agent can map the claims of US12103576B2 against your product specifications, identify prior art that may support invalidity arguments, and flag related patents in the same family or classification. For procurement and product development teams operating in the home storage category, an automated FTO workflow through Eureka reduces time-to-clearance and flags risk before commercial commitments are made — not after a complaint lands in your inbox.

What this case signals for the consumer storage products IP landscape
A 62-day voluntary dismissal without prejudice rarely signals the end of a dispute — it often marks a strategic pause.
Without-prejudice dismissals preserve re-filing rights — monitor closely
Dbest and similarly positioned sellers should treat this dismissal as a temporary reprieve, not a clean exit. Jinhuanshi retains full rights to re-assert US12103576B2. Any seller of stackable storage bins on Amazon should conduct an FTO review against this patent before expanding their product line.
Pre-hearing withdrawal suggests off-docket activity worth tracking
Filing the dismissal notice the day before a scheduled court appearance is consistent with a last-minute settlement or licensing agreement. While the record is silent, competitors in this product space should watch for licensing outreach from Hhuohuachichi entities targeting similar Amazon ASINs.
jinhuanshiyehedianzishangwuyouxiangonsi v Dbest — key questions answered
Jinhuanshi (d/b/a Hhuohuachichi) filed a patent infringement action against Dbest Products Inc. in the Northern District of Illinois on 27 December 2024 over US12103576B2 covering stackable storage bins. The plaintiff voluntarily dismissed the case without prejudice on 27 February 2025, 62 days after filing, under Rule 41(a)(1)(A)(i), before any merits ruling was entered.
A dismissal without prejudice means Jinhuanshi can re-file the same infringement claims against Dbest at a future date, subject to the applicable statute of limitations. Dbest faces no adverse judgment or liability from this termination, but the patent threat under US12103576B2 is not permanently extinguished. Dbest may benefit from seeking an IPR or FTO clearance to reduce future exposure.
The complaint identified five Amazon ASINs sold by Dbest Products Inc.: B0CGD1R87W, B0DGTP4PZJ, B0CGD1W4P6, B0D93RMSVD, and B0D9BCZJSK — all described as stackable storage bins. Products sold through dbest-products.com were also referenced in the litigation.
The public record does not disclose the reason for the rapid dismissal. The timing — filed the day before a scheduled in-person hearing — is consistent with a private settlement, licensing agreement, or strategic withdrawal. Because the dismissal was filed under Rule 41(a)(1)(A)(i) before Dbest answered, no court order or explanation was required, and no terms were disclosed on the docket.
US12103576B2 is a U.S. patent held by Jinhuanshi Electronic Commerce Co. filed under application number US18/542495. It covers stackable storage bin technology, likely including structural or geometric elements relating to modular stacking, interlocking features, or storage bin design. The patent was asserted against Dbest’s consumer storage products sold on Amazon and through the Dbest direct website.
