Zemiao Chen v. Schedule A Defendants: Design Patent Dismissed After Inactivity
Zemiao Chen filed an infringement action in Florida’s Southern District asserting design patent USD1019124S covering a beach bag and seashell bag design against a group of anonymous online sellers. After 228 days and no plaintiff activity, Judge Singhal dismissed the case without prejudice — also flagging it as potentially duplicative of a parallel action.
Court-Initiated Dismissal in a Schedule A Design Patent Action
On June 15, 2024, plaintiff Zemiao Chen, represented by Palmer Law Group PA, filed suit in the U.S. District Court for the Southern District of Florida alleging infringement of design patent USD1019124S — an ornamental design for a beach bag or seashell bag — against a wide class of anonymous online sellers identified only as ‘Schedule A’ defendants, a common enforcement structure used in e-commerce IP actions.
Following six months of inactivity on the docket, Judge Raag Singhal issued an Order for Status Report on January 24, 2025, directing Chen to file a status report by January 28, 2025. Plaintiff filed nothing. The court then dismissed the case without prejudice on January 29, 2025, and denied all pending motions as moot. Dismissal without prejudice means Chen retains the legal right to refile the same claims, though no settlement, judgment, or merits ruling was reached.
Notably, the court flagged the case as ‘duplicative’ of Case No. 24-60863-CIV-AHS, suggesting Chen had filed substantially the same action in the same district — a pattern sometimes seen when plaintiffs pursue parallel tracks or test different case assignments. The public record does not disclose why plaintiff went silent, whether a settlement was reached privately, or what the status of the parallel case is. The 228-day duration without any substantive ruling is consistent with cases abandoned after early-stage enforcement leverage is exhausted.

Dismissed without prejudice: what the court’s order means for both sides
Court-initiated dismissal for plaintiff inactivity
Under Federal Rule of Civil Procedure 41(b), courts may dismiss an action for failure to prosecute. Here, Judge Singhal first issued a show-cause-style status report order; when plaintiff failed to respond by the deadline, the court dismissed sua sponte. The ‘without prejudice’ designation means the dismissal does not bar refiling — it carries no res judicata effect on the merits.
FRCP 41(b) — failure to prosecuteNo merits loss — but enforcement momentum is gone
Chen retains USD1019124S in full force and may refile against the same or different defendants. However, any preliminary injunctions or TROs obtained in this action would be dissolved on closing. The court’s note about a duplicative parallel case (24-60863) suggests the patent may still be actively asserted elsewhere, but this specific action produced no enforceable outcome.
Patent survives — no injunctive relief securedDefendants escape without prejudicing future defence
Schedule A defendants — likely online marketplace sellers — face no judgment, injunction, or damages award from this case. Because dismissal is without prejudice, defendants cannot claim they have been cleared of infringement. If Chen refiles or pursues the parallel action, defendants may face the same claims again. No defendant counsel appeared, consistent with the anonymous-seller enforcement model.
No judgment — re-exposure risk remainsSchedule A tactics under judicial scrutiny in S.D. Fla.
The court’s flagging of this case as duplicative of a parallel filing signals growing judicial awareness of multi-track Schedule A enforcement strategies. Southern District of Florida judges are increasingly scrutinising simultaneous or near-identical filings. For IP counsel advising e-commerce clients, this case suggests courts may consolidate or dismiss parallel actions, increasing the cost-efficiency risk of the Schedule A playbook.

Official order — verbatim text
The court’s order is procedural rather than substantive: dismissal was triggered by plaintiff’s failure to file a court-ordered status report, not by any ruling on infringement, validity, or claim construction. The ‘duplicative’ flag is analytically significant — it suggests the court may have been prepared to consolidate or dismiss regardless of plaintiff activity. No party received a merits adjudication. The without-prejudice designation leaves the legal landscape unchanged for both Chen and the anonymous defendants.
USD1019124S — Ornamental Design for a Beach Bag / Seashell Bag
USD1019124S is a U.S. design patent granted on the ornamental appearance of a beach bag or seashell bag, filed as application US29/798341. Design patents protect the non-functional, visual characteristics of a product — in this case, the distinctive aesthetic of the bag’s shape, surface ornamentation, or silhouette. Design patents typically have a 15-year term from grant and are frequently asserted against overseas manufacturers and marketplace sellers who copy the visual design of consumer accessories.
In the highly fragmented beach accessories and seasonal bags market, ornamental design rights are among the primary enforcement tools for individual designers and small brands competing against high-volume online sellers. USD1019124S sits within a category where near-identical products are routinely listed across Amazon, Temu, and similar platforms by Schedule A sellers. The patent’s commercial value is tied directly to enforcement activity — without an injunction or judgment, it functions primarily as a deterrent and licensing leverage instrument.
Should your team run an FTO against USD1019124S?
Any brand or seller manufacturing, importing, or listing beach bags, seashell-shaped bags, or visually similar coastal accessories in the U.S. market should assess exposure to USD1019124S. This is particularly relevant for marketplace sellers on Amazon, Walmart, and Temu, as well as private-label importers sourcing from manufacturers in China. The parallel case 24-60863 may still be active, meaning enforcement risk has not been extinguished by this dismissal.

What this case signals for design patent enforcement in e-commerce
This dismissal illustrates pressure points in the Schedule A enforcement model — inactivity, duplicative filings, and judicial pushback.
Parallel filings in Schedule A cases draw judicial scrutiny
Judge Singhal explicitly noted this case appeared duplicative of 24-60863-CIV-AHS. For IP practitioners using multi-track filing strategies against anonymous e-commerce sellers, this is a material warning: Southern District of Florida judges are actively cross-referencing dockets and may dismiss redundant actions without waiting for parties to raise the issue.
Without prejudice dismissal preserves patent — but erodes enforcement credibility
USD1019124S remains valid and assertable after this dismissal. However, a court-ordered closure for inactivity signals to future defendants and their counsel that the plaintiff’s enforcement posture may be opportunistic. Defendants in any refiled action could use the docket history to argue for early dismissal or fee-shifting if litigation conduct appears abusive.
Chen v Individuals — key questions answered
The case was dismissed without prejudice on January 29, 2025, by Judge Raag Singhal of the Southern District of Florida. Plaintiff Zemiao Chen failed to respond to a court-ordered status report after six months of inactivity. No merits ruling was issued. The court also noted the case appeared duplicative of parallel action 24-60863-CIV-AHS.
Yes. A without-prejudice dismissal for failure to prosecute has no effect on patent validity. USD1019124S remains in force unless separately challenged at the USPTO via inter partes review or cancelled through another legal proceeding. Chen retains the right to assert the patent in a refiled or ongoing parallel action.
Dismissed without prejudice means defendants face no judgment, injunction, or damages award from this specific action. However, it also means they have not been adjudicated non-infringing — the plaintiff may refile the same claims. Any account freezes or marketplace restrictions tied to this case number would typically be lifted on case closure, but the parallel action may create separate exposure.
A ‘Schedule A’ defendant structure is used in e-commerce IP enforcement where the plaintiff cannot identify individual sellers before filing. The complaint names a class of unknown online sellers, with a sealed schedule listing marketplace handles or store URLs. Courts in S.D. Florida routinely grant ex parte TROs to freeze seller accounts pending identification. This structure is common for design patent and trademark actions against marketplace infringers.
The court noted that Case No. 0:24-cv-61036 appeared duplicative of 24-60863-CIV-AHS, suggesting Chen had filed substantially identical infringement claims in two separate S.D. Florida actions, potentially before different judges. Courts in this district have grown increasingly attentive to parallel Schedule A filings and may dismiss or consolidate redundant actions. The public record does not confirm whether the same defendants or the same patent are at issue in both cases.
