Dbest Products v. Jieyang Juxiaonian: Portable Cart Patents Dismissed Without Prejudice
California-based Dbest Products filed suit against Chinese importer Jieyang Juxiaonian Trading Co., asserting two portable cart patents — US12275446B2 and US12304546B1 — before voluntarily dismissing without prejudice just 118 days later, with each party bearing its own costs.
Portable cart patent suit exits before defendant enters the arena
On May 21, 2025, Dbest Products Inc. filed an infringement action in the U.S. District Court for the Central District of California against Jieyang Juxiaonian Trading Co., Ltd., a Chinese trading company. The complaint asserted two utility patents — US12275446B2 and US12304546B1 — both directed to portable cart technology, a product category where Dbest competes against a wave of lower-cost imports sold through online marketplaces.
On September 16, 2025, Dbest filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), citing that the defendant had not yet filed an answer or a motion for summary judgment, and that Dbest had not previously dismissed a federal or state action on the same claims. The dismissal was expressly without prejudice, meaning Dbest retains the legal right to refile the same claims against the same defendant. Each party was ordered to bear its own costs, fees, and expenses.
The 118-day timeline — resolved entirely before any responsive pleading — is consistent with several scenarios common in import-enforcement matters: an out-of-court resolution, difficulty serving a foreign defendant, or a tactical reassessment of litigation strategy. Because the dismissal is without prejudice and no settlement terms are disclosed on the public record, the commercial relationship between the parties and any potential payment or undertaking remains unknown.

Voluntarily dismissed without prejudice: what the record reveals
Rule 41(a)(1)(A)(i): unilateral right to dismiss before answer
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order at any point before the defendant serves an answer or a motion for summary judgment. Because Jieyang Juxiaonian had not filed either, Dbest exercised this right unilaterally. The dismissal is effective upon filing — no judicial approval is required. Critically, the filing expressly states the dismissal is without prejudice, preserving Dbest’s ability to refile.
Procedural voluntary dismissalWithout prejudice: the door remains open for Dbest
A dismissal without prejudice means the claims are not adjudicated on their merits and no bar to refiling exists. Dbest explicitly invoked Rule 41(a)(1)(B) to confirm the without-prejudice character. This contrasts with a dismissal with prejudice, which would permanently extinguish the asserted claims. The public record does not disclose whether any private settlement, licensing agreement, or undertaking was reached — meaning the commercial resolution, if any, is unknown.
No merits bar; refile rights intactJieyang Juxiaonian exits without admitting infringement
Because the case was dismissed before any responsive pleading and without prejudice, Jieyang Juxiaonian faces no injunction, no damages award, and no finding of infringement. The defendant was never required to engage on the merits. However, the without-prejudice nature means this is not a clean legal exit — Dbest could refile, potentially after gathering additional evidence or adjusting litigation strategy. The absence of defendant counsel on the record may suggest the defendant did not formally appear.
No liability; risk of refiling remainsPattern enforcement against import competitors: watch the docket
Dbest’s assertion of two recently issued portable cart patents against a Chinese trading company is consistent with a broader enforcement strategy targeting imported competing products. A swift without-prejudice dismissal may signal a private resolution, or alternatively a repositioning before refiling. Companies operating in the portable cart and consumer goods import space — particularly those selling via U.S. e-commerce channels — should monitor Dbest’s patent portfolio and any subsequent enforcement actions against similar importers.

Official order — verbatim text
The dismissal notice precisely tracks the requirements of Rule 41(a)(1)(A)(i): plaintiff confirms no answer or summary judgment motion has been filed, and no prior dismissal of the same claims exists. The express invocation of Rule 41(a)(1)(B) to confirm the without-prejudice character is a deliberate legal step, not boilerplate — it ensures no ‘two-dismissal rule’ trap applies if Dbest refiles. The cost-neutrality provision, while standard, is consistent with a negotiated exit rather than a purely unilateral strategic retreat.
US12275446B2 & US12304546B1 — Portable Cart Technology
US12275446B2 (application no. US18/460131) and US12304546B1 (application no. US19/032431) both relate to portable cart technology — a product category encompassing folding carts, utility carts, and consumer mobility goods sold broadly through retail and e-commerce channels. Their sequential application numbers and ‘B2’/’B1’ grant designations suggest these are recently issued utility patents, placing Dbest at the beginning of their statutory enforcement window. The specific claim scope — whether directed to structural features, folding mechanisms, materials, or configurations — would require review of the issued claims.
In the portable consumer goods sector, patent rights over cart design and utility features can be commercially decisive, particularly as the market faces intense price competition from imported products. Dbest’s decision to assert two patents simultaneously against a Chinese trading company suggests a layered IP strategy intended to create broad claim coverage and raise the cost of design-around. For competitors in the folding cart, utility cart, and consumer mobility space, both patents represent active enforcement assets that could generate additional litigation against importers, distributors, and online marketplace sellers.
Should your product team run an FTO against US12275446B2 and US12304546B1?
Any company importing, manufacturing, or distributing portable carts — including folding carts, utility carts, and similar consumer mobility products — for the U.S. market should treat both Dbest patents as live risk assets. The without-prejudice dismissal confirms Dbest retains full enforcement rights. Companies selling through Amazon, Walmart, or other U.S. e-commerce channels are particularly exposed, as import-enforcement actions frequently target marketplace sellers and their supply chains.

What this case signals for the portable cart and consumer goods IP landscape
A pre-answer voluntary dismissal rarely closes the enforcement story — particularly where recently issued patents and import competition are involved.
Pre-answer dismissals often precede private resolutions or refiling
When a plaintiff with newly issued patents drops a case before the defendant appears on record, it typically signals either a private agreement (unlicensed on public terms) or a tactical reset. Either scenario warrants monitoring for subsequent filings by Dbest against this or related defendants in the portable cart category.
Both asserted patents are recently issued — enforcement risk is real and active
US12275446B2 and US12304546B1 appear to be recently granted patents, suggesting Dbest is in an early enforcement phase. Companies in the portable cart, folding cart, and consumer mobility product space should treat these as live enforcement assets and conduct freedom-to-operate analysis before product launch or import.
Dbest v Jieyang — key questions answered
The case was dismissed without prejudice. Dbest Products explicitly invoked Federal Rule of Civil Procedure 41(a)(1)(B) to confirm the without-prejudice character of the dismissal, meaning Dbest retains the right to refile the same patent infringement claims against Jieyang Juxiaonian Trading Co. in the future.
Dbest Products asserted two patents: US12275446B2 (application no. US18/460131) and US12304546B1 (application no. US19/032431). Both patents relate to portable cart technology and appear to be recently issued utility patents based on their grant designations and sequential application numbers.
The public record does not disclose the reason for dismissal. The without-prejudice dismissal before any responsive pleading was filed by Jieyang Juxiaonian is consistent with several scenarios: a private out-of-court resolution, a licensing agreement, difficulty serving a foreign defendant, or a tactical reassessment of enforcement strategy. No settlement terms appear on the public docket.
The dismissal notice expressly provides that each party bears its own costs, fees, and expenses. No fee-shifting was ordered and no award of attorney fees was made. This cost-neutrality provision is standard in Rule 41(a)(1) voluntary dismissals but may also reflect a negotiated exit between the parties.
Yes. Because the dismissal was without prejudice and this was Dbest’s first dismissal of a federal or state action based on the same claims — as expressly stated in the filing — the ‘two-dismissal rule’ under Rule 41(a)(1)(B) does not apply. Dbest retains the full right to refile the same portable cart patent claims against Jieyang Juxiaonian or other defendants.
