Kitsch LLC v. Leafinity: Design Patent Infringement Dismissed Without Prejudice
Kitsch LLC, a beauty accessories brand, sued Chinese e-commerce seller Leafinity in the Northern District of Illinois over alleged infringement of design patent USD0926471S covering a soap bag. The case was voluntarily dismissed without prejudice just 93 days after filing, leaving the door open for re-filing.
Design patent dispute over a soap bag ends before defendant responds
On 7 October 2024, Kitsch LLC filed a design patent infringement action in the U.S. District Court for the Northern District of Illinois (Case No. 1:24-cv-09663) against Chengduhechuangjietongdianzishangwuyouxiangongsi, a Chinese e-commerce entity operating under the brand name Leafinity. The asserted patent, USD0926471S (App. No. US29/745514), protects the ornamental design of a soap bag — a consumer beauty and personal care accessory. Leafinity’s accused products comprised at least six Amazon ASINs in the soap bag product category.
The case was terminated on 8 January 2025 — just 93 days after filing — when Kitsch LLC filed a voluntary notice of dismissal without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). This procedural mechanism is available before the defendant has served an answer or a motion for summary judgment, requiring no court order and no defendant consent. A dismissal without prejudice means Kitsch retains the right to re-file the same claims against Leafinity or related entities in a future action, subject to applicable statutes of limitations.
The sub-100-day resolution before any substantive defence was filed is consistent with early-stage settlement negotiations, a licensing arrangement, or a commercial agreement to cease the accused product listings — none of which would necessarily appear in the public record. The absence of defendant counsel on the docket suggests Leafinity may not have retained U.S. litigation counsel, which can be a significant driver toward early resolution in actions against foreign e-commerce sellers. What drove the ultimate dismissal — whether a commercial deal, voluntary product removal, or strategic withdrawal — remains unknown from the public record.

Dismissed without prejudice: what Rule 41 means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit before answer
Fed. R. Civ. P. 41(a)(1)(A)(i) allows a plaintiff to dismiss its own complaint without a court order, and without defendant consent, provided the defendant has not yet served an answer or summary judgment motion. The dismissal takes effect immediately upon filing. No judicial approval is required, making this one of the cleanest procedural exits available in U.S. federal litigation.
Voluntary, unilateral dismissalWithout prejudice: the claims live on
A dismissal without prejudice does not extinguish Kitsch’s underlying patent infringement claims. Kitsch LLC retains the right to re-file suit on USD0926471S against Leafinity or related sellers, provided it does so within the applicable limitations period. This contrasts with a with-prejudice dismissal, which would bar re-filing on the same claims. The public record does not disclose whether any settlement, licence, or undertaking was reached.
Claims remain viableLeafinity faces no judgment — but no permanent shield
Leafinity obtained a practical exit from this litigation without having to defend on the merits or incur the cost of U.S. legal representation. However, the without-prejudice nature of the dismissal means Leafinity cannot treat this as a final resolution. If the accused product listings remain active or the parties have not reached a commercial arrangement, re-filing risk persists. No injunction, damages award, or consent decree appears on the public record.
No merits adjudicationCross-border design enforcement: early exit patterns
Cases against Chinese Amazon sellers asserting U.S. design patents frequently resolve pre-answer, often following ASIN removal or informal negotiation. The six accused ASINs in the soap bag category suggest Leafinity had meaningful sales exposure. For competitors in the beauty accessories space operating similar product lines, this case signals that Kitsch LLC is actively monitoring its design IP — even if this particular action did not proceed to merits adjudication.

Official order — verbatim text
The dismissal notice precisely invokes Rule 41(a)(1)(A)(i), confirming this was a unilateral plaintiff action requiring no court order and no defendant consent — consistent with the absence of any defendant appearance on the docket. The without-prejudice qualifier is legally significant: it preserves Kitsch’s full ability to reassert USD0926471S against Leafinity in a future proceeding. The verdict text contains no reference to settlement terms, licence grant, or undertaking by Leafinity, meaning the commercial basis for dismissal — if any — is not disclosed in the public record.
USD0926471S — Ornamental Design for a Soap Bag
USD0926471S (Application No. US29/745514) is a U.S. design patent protecting the ornamental appearance of a soap bag — a personal care accessory used to hold bar soap and typically constructed from mesh or fabric. Design patents under 35 U.S.C. § 171 protect only the non-functional, visual characteristics of an article of manufacture. The ‘USD’ prefix designates a design patent, distinct from utility patents, and protection turns on whether an ordinary observer would find the accused product substantially similar to the claimed design.
In the consumer beauty accessories market, design patents are increasingly deployed to differentiate products sold through e-commerce platforms where visual appearance is the primary purchasing driver. Kitsch LLC’s enforcement of USD0926471S against a seller with six distinct Amazon ASINs in the soap bag category signals that the company views this design as commercially material. Competitors manufacturing or importing soap bags, mesh pouches, or similar personal care accessories should assess whether their product aesthetics fall within the scope of this design registration, particularly if selling on Amazon’s U.S. marketplace.
Should your soap bag product line be cleared against USD0926471S?
Any brand, manufacturer, or Amazon seller offering soap bags, mesh bath pouches, or similar personal care accessories in the U.S. market should consider a freedom-to-operate review against USD0926471S. The without-prejudice dismissal in this case confirms Kitsch LLC’s willingness to enforce this design and retains their right to re-file. Products sharing the ornamental profile of the patented soap bag design are at genuine risk of a renewed action, particularly if sold through Amazon where ASIN-level identification makes target selection straightforward.
PatSnap Eureka’s FTO Search Agent can map the visual scope of USD0926471S against your product designs, identify prior art that may narrow or invalidate the claimed ornamental features, and surface related Kitsch LLC design filings that may represent further enforcement risk. For product teams launching or scaling soap bag or bath accessory lines, proactive FTO analysis is materially cheaper than defending an infringement action — even one that resolves pre-judgment.

What this case signals for the beauty accessories design IP landscape
Short-duration dismissals against Amazon sellers can be as strategically significant as full trials — here is what practitioners and product teams should note.
Design patents remain a sharp tool against Amazon marketplace sellers
Kitsch’s filing strategy — asserting a design patent against a foreign Amazon seller with multiple accused ASINs — is a recognised enforcement pattern. Even without a final judgment, the filing alone can trigger ASIN removal requests, seller account pressure, and informal resolution. Product teams selling adjacent beauty accessory designs should treat USD0926471S as a live enforcement risk.
Without-prejudice exits preserve plaintiff optionality at low cost
By dismissing under Rule 41(a)(1)(A)(i), Kitsch incurred minimal court process costs while keeping its legal options fully open. This approach is increasingly common where plaintiffs achieve their commercial objective — e.g. product delisting — without needing a damages award. IP counsel should note that the speed of resolution here (93 days) suggests early commercial engagement rather than protracted defence.
Kitsch v CHENGDUHECHUANGJIETONGDIANZISHANGWUYOUXIANGONGSI — key questions answered
Kitsch LLC asserted U.S. design patent USD0926471S (Application No. US29/745514), which protects the ornamental design of a soap bag. The accused products were six Amazon ASINs sold by Leafinity, a Chinese e-commerce entity.
Kitsch LLC voluntarily dismissed the case under Fed. R. Civ. P. 41(a)(1)(A)(i), which permits a plaintiff to withdraw claims unilaterally before the defendant files an answer. The public record does not disclose whether a settlement, licence, or product removal agreement drove the decision.
Yes. A dismissal without prejudice does not bar re-filing. Kitsch LLC retains the right to reassert infringement claims based on USD0926471S against Leafinity or related entities, provided the action is brought within the applicable statute of limitations period.
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss its complaint without a court order and without the defendant’s consent, as long as the defendant has not yet served an answer or a motion for summary judgment. The dismissal is immediate upon filing and, unless specified otherwise, is without prejudice.
The complaint identified six Amazon product listings (ASINs: B0BYSQNF5B, B0BYSS238G, B0BYSS6VKB, B0BYSSV66F, B0BYZJYXXK, and B0CM3J32LD) sold by Leafinity, all in the soap bag product category, as accused of infringing the ornamental design claimed in USD0926471S.
