Taizhou Xiaotanglang v. Schedule A Defendants: Bath Tub Design Patent Dismissed
Chinese infant products maker Taizhou Xiaotanglang asserted design patent USD1013129S — covering a baby bath tub — against a group of unnamed online defendants in Florida’s Southern District. The case was voluntarily dismissed without prejudice just 135 days after filing, leaving the door open for future enforcement.

Voluntary dismissal without prejudice: what the record shows
Voluntary dismissal without prejudice explained
A voluntary dismissal without prejudice means the plaintiff elected to end the case before any merits ruling. Crucially, ‘without prejudice’ preserves the plaintiff’s right to refile the same claims against the same or different defendants. No court judgment on infringement, validity, or damages was entered, and the defendants received no formal legal victory.
Plaintiff-initiated exitTaizhou Xiaotanglang retains full right to refile
By dismissing without prejudice, Taizhou Xiaotanglang keeps USD1013129S fully intact and enforceable. The dismissal imposes no estoppel or preclusion. The plaintiff may re-assert these design patent claims — against the same Schedule A defendants or newly identified infringers — in a fresh action, subject to applicable statutes of limitations.
Enforcement optionality preservedDefendants exit without prejudice — no lasting protection
The Schedule A defendants secured no declaratory judgment of non-infringement or invalidity. A dismissal without prejudice does not bar future suit. Any defendant that continues selling the accused bath tub products remains exposed to a renewed infringement action. The lack of a merits ruling means this outcome offers defendants limited long-term certainty.
Re-exposure risk remainsDesign patent risk persists for online bath tub sellers
Schedule A litigation targeting e-commerce sellers of infant products is a recurring enforcement strategy. A without-prejudice dismissal is commonly associated with out-of-court settlements or strategic case management rather than a concession on the merits. Sellers of ornamental baby bath tub designs on online marketplaces should treat this dismissal as a pause, not a clearance.

Official order — verbatim text
The voluntary dismissal notice is unambiguous on one key point: the case is dismissed ‘without prejudice,’ meaning no merits adjudication occurred. The record contains no judgment on infringement of USD1013129S, no validity ruling, and no damages award. For defendants, this is procedural relief only — it carries no res judicata effect and provides no shield against a subsequent action asserting the same design patent claims.
USD1013129S — Baby Bath Tub Ornamental Design Patent
USD1013129S is a U.S. design patent protecting the ornamental appearance of a baby bath tub, filed under application number US29/904849. Design patents cover the visual and aesthetic characteristics of a product — not its function — and grant the holder the exclusive right to the specific ornamental design as depicted in the patent drawings. Infringement is assessed under the ‘ordinary observer’ test established in Egyptian Goddess v. Swisa.
In the highly competitive infant and child products market, ornamental design rights are strategically significant. Baby bath tubs sold through online marketplaces often feature closely similar silhouettes and styling. A design patent like USD1013129S gives a Chinese manufacturer — increasingly active in U.S. IP enforcement — a tool to challenge copycat listings across major e-commerce platforms, particularly in the context of Schedule A ‘John Doe’ litigation.
Should you run an FTO analysis against USD1013129S?
Any company designing, importing, or selling baby bath tubs through U.S. e-commerce channels should treat USD1013129S as an active enforcement risk. Because the case was dismissed without prejudice, the patent remains in force and the plaintiff retains full rights to refile. Sellers whose bath tub designs share visual similarities with the patented ornamental design face potential exposure — particularly those operating as Schedule A-type online storefronts.
PatSnap Eureka’s FTO Search Agent can cross-reference USD1013129S against your product design, flag similar design patents held by Taizhou Xiaotanglang or related entities, and surface litigation history across U.S. district courts. For infant product companies expanding into the U.S. market, a design patent clearance search before listing is a cost-effective first line of defence against Schedule A actions.

What this case signals for the infant products design patent landscape
Schedule A design patent actions in Florida are a well-worn enforcement tactic. This dismissal pattern warrants close attention from e-commerce IP teams.
Without-prejudice exits often mask private resolutions
Voluntary dismissals without prejudice in Schedule A cases frequently follow informal settlements or licensing agreements that never appear on the public docket. IP teams monitoring Taizhou Xiaotanglang’s enforcement posture should track subsequent filings — a refile within months would suggest the original exit was strategic rather than substantive.
Design patents on infant products carry real enforcement weight
USD1013129S is an ornamental design patent — the legal threshold for infringement is the ‘ordinary observer’ test, which can be easier to satisfy than utility patent infringement standards. E-commerce sellers of baby bath products should assess visual similarity carefully, not just functional differences, when evaluating infringement risk.
TAIZHOU v Individuals — key questions answered
It means Taizhou Xiaotanglang chose to end the case before any court ruling on the merits. ‘Without prejudice’ preserves the right to refile identical claims. No judgment of infringement or non-infringement was entered, and design patent USD1013129S remains fully enforceable.
Yes. A voluntary dismissal without prejudice has no effect on patent validity or enforceability. USD1013129S was not invalidated, and no finding of non-infringement was made. The patent holder retains all rights and may assert the patent in future proceedings.
Schedule A defendants are unnamed parties — typically online marketplace sellers — listed on a sealed exhibit filed with the complaint. Plaintiffs use this approach to file quickly before defendants can hide assets, later identifying specific defendants through third-party subpoenas to platforms like Amazon. It is a common tactic in e-commerce IP enforcement.
Florida’s Southern District has developed extensive experience with Schedule A e-commerce cases. Judges there are familiar with TRO and asset-freeze procedures used against online sellers. The court’s procedural familiarity and established precedents make it a strategically attractive venue for IP holders pursuing online marketplace infringers.
Under the ‘ordinary observer’ test from Egyptian Goddess v. Swisa (Fed. Cir. 2008), a design patent is infringed if an ordinary observer, familiar with the prior art, would consider the accused design substantially similar to the patented design. Functional differences alone are insufficient to avoid infringement — visual similarity is the controlling standard.
