Ye v. Guangzhoushikaermansixinxikejiyouxiangongsi: Design Patent Dispute Ends in Voluntary Dismissal
Jiaxiang Ye filed suit in the Southern District of New York alleging infringement of two USD design patents covering decorative ribbed glass ceiling light shades and vintage-style bulb accessories. The case closed 228 days after filing via voluntary dismissal, with the parties required to correct procedural deficiencies in their stipulation before the court would accept it.
Design Patent Dispute Over Glass Lighting Shades Resolves Without Merits Ruling
On April 27, 2024, individual plaintiff Jiaxiang Ye filed an infringement action in the U.S. District Court for the Southern District of New York against Guangzhoushikaermansixinxikejiyouxiangongsi, a Guangzhou-based technology and electronics company. The complaint alleged infringement of two U.S. design patents — USD0997438S and USD1017877S — covering the ornamental appearance of decorative ribbed glass ceiling light shades and related vintage lighting accessories sold through online channels including Amazon.
The case closed on December 11, 2024, 228 days after filing, following a joint stipulation of voluntary dismissal filed by both parties on December 4, 2024. The court did not enter a dismissal outright; instead, Judge Mary Kay Vyskocil ordered the parties to correct procedural deficiencies in their stipulation and refile a corrected version by December 20, 2024. The basis of termination is recorded as voluntary dismissal. Critically, the public record does not specify whether the dismissal was with or without prejudice, leaving that distinction unresolved in the available docket.
A 228-day resolution is relatively swift for design patent litigation in S.D.N.Y. and is consistent with a negotiated resolution — whether a settlement, license, or cessation of the accused conduct — reached before any substantive merits briefing. The absence of any recorded verdict, damages award, or fee ruling means the precise commercial terms, if any, remain undisclosed. What drove the resolution cannot be confirmed from the public record alone, though the bilateral nature of a stipulated dismissal typically suggests mutual agreement rather than unilateral abandonment.

Voluntarily dismissed: what the stipulation means for each party
What a stipulated voluntary dismissal means in practice
A stipulated voluntary dismissal under Federal Rule of Civil Procedure 41 is a bilateral procedural act — both parties agree to end the litigation. Unlike a court judgment, it does not constitute a ruling on the merits of the patent claims. Here, the court flagged deficiencies in the parties’ December 4, 2024 stipulation and ordered a corrected filing, but the ultimate disposition remains voluntary dismissal rather than any adjudicated outcome.
No merits adjudicationThe public record is silent on prejudice — and that gap matters
A dismissal ‘with prejudice’ bars Ye from refiling the same design patent claims against this defendant. A dismissal ‘without prejudice’ preserves that right. Under Rule 41, a stipulated dismissal is presumed without prejudice unless the stipulation states otherwise. However, the available docket record does not confirm which applies here. IP professionals tracking this case should monitor the corrected stipulation filing for clarification on this commercially significant distinction.
Prejudice status unconfirmedYe exits without a recorded win — but terms may be privately favourable
Jiaxiang Ye obtains no public judgment enforcing the design patents. However, voluntary dismissals in design patent cases frequently accompany private settlements involving product redesigns, licence fees, or takedown commitments. Without a merits ruling, the patents USD0997438S and USD1017877S remain valid and enforceable against third parties, preserving Ye’s ability to pursue future infringement actions on the same IP.
Patents remain enforceableDismissal ends litigation exposure — for now
The defendant avoids a potentially adverse design patent judgment and any public damages award. If the dismissal is without prejudice, residual litigation risk persists should the accused product remain on the market. If with prejudice, exposure to Ye’s specific claims is extinguished. The defendant’s decision to stipulate jointly, rather than litigate, suggests a pragmatic commercial calculus — consistent with the pattern seen among Chinese e-commerce sellers facing U.S. design patent suits.

Official order — verbatim text
The court’s December 4, 2024 order reveals a procedurally imperfect dismissal: the parties’ stipulation contained deficiencies identified by Clerk’s Office staff, and Judge Vyskocil directed correction rather than immediate entry. This suggests the dismissal had not yet been formally accepted as of the case close date. The absence of any merits language in the court’s order confirms that no patent validity or infringement determination was made — the case ends solely on procedural resolution, leaving the design patents unexamined by the court.
USD0997438S & USD1017877S — Ornamental Glass Lighting Shade Designs
USD0997438S (App. No. 29/891,803) and USD1017877S (App. No. 29/834,114) are U.S. design patents protecting the ornamental appearance — not the functional features — of decorative glass lighting products. Design patents in the ’29/’ application series are typically granted within 12–18 months of filing and carry a 15-year term from grant. The asserted products include ribbed-glass ceiling light shades and vintage-style scented or dimmable bulb accessories marketed through Amazon and UK lighting retail channels.
In the decorative lighting accessory market — heavily populated by Chinese manufacturers supplying global e-commerce platforms — design patent portfolios have become a meaningful enforcement tool for smaller design originators. A granted USD design patent creates a presumption of validity that places the burden of proof on any challenger. For competitors operating in the ribbed-glass and vintage-shade segment, the existence of two granted design patents from the same apparent portfolio holder signals an enforcement-minded posture that warrants proactive FTO analysis.
Should your product team run an FTO against USD0997438S and USD1017877S?
Any manufacturer, importer, or Amazon third-party seller dealing in decorative glass ceiling light shades, ribbed glass lamp shades, or vintage-style bulb accessories targeting the U.S. market should treat these two design patents as live enforcement risks. The voluntary dismissal in this case does not invalidate either patent — both remain in force and could anchor future infringement actions against new defendants with visually similar products.

What this case signals for the decorative lighting design patent landscape
Design patent enforcement against online-marketplace sellers is a growing S.D.N.Y. pattern. This case illustrates the lifecycle.
S.D.N.Y. is an increasingly active venue for design patent suits against Chinese online sellers
This case follows a recognisable enforcement template: individual or small-entity U.S. design patent holders filing in S.D.N.Y. against Chinese e-commerce sellers distributing via Amazon or similar platforms. The relatively short duration and joint stipulation are consistent with defendants choosing commercial resolution over expensive U.S. litigation defence.
Design patents on lighting accessories carry real enforcement leverage despite narrow scope
USD design patents protect ornamental appearance only, not function. Yet in e-commerce contexts — where product images drive purchasing decisions — even modest visual similarity can support a plausible infringement claim. Manufacturers and importers of decorative glass lighting shades should assess their product designs against granted USD design patents in this category.
Ye v Guangzhoushikaermansixinxikejiyouxiangongsi — key questions answered
Two U.S. design patents were asserted: USD0997438S (App. No. 29/891,803) and USD1017877S (App. No. 29/834,114). Both protect the ornamental appearance of decorative glass lighting accessories, including ribbed glass ceiling light shades and vintage-style bulb products sold via Amazon and UK retail channels.
The parties filed a joint stipulation of voluntary dismissal on December 4, 2024. The court identified procedural deficiencies and ordered a corrected filing by December 20, 2024. The basis of termination is voluntary dismissal, consistent with a negotiated resolution, though no settlement terms are publicly disclosed. No merits ruling on the design patents was issued.
The public docket record does not specify whether the voluntary dismissal was with or without prejudice. Under FRCP Rule 41, a stipulated dismissal is presumed without prejudice unless stated otherwise. The corrected stipulation ordered by Judge Vyskocil, if filed, may clarify this. IP professionals monitoring Ye’s enforcement activity should track the corrected filing on the S.D.N.Y. docket.
Yes. A voluntary dismissal does not invalidate or cancel the asserted design patents. USD0997438S and USD1017877S remain in force and enforceable against third parties. The dismissal only ends this specific litigation against this specific defendant and does not constitute a ruling on patent validity or infringement.
Judge Vyskocil’s December 4, 2024 order directed the parties to correct deficiencies in their voluntary dismissal stipulation rather than immediately entering the dismissal. This is procedurally notable: it means the dismissal was not immediately accepted, and the corrected stipulation may contain additional terms — including prejudice status — not yet visible in the public record. The case close date of December 11, 2024 predates the December 20 correction deadline.
