Kids2 LLC v. Carter’s Inc.: Activity Center Patent Suit Dismissed in 3 Days
Kids2 LLC sued Carter’s Inc. and Skip Hop entities in the Eastern District of Texas asserting US7740560B2 against the Skip Hop Explore & More and related activity center product lines. The case closed just 3 days after filing — before defendants were served — via voluntary dismissal without prejudice under Rule 41.
A 72-Hour Patent Filing: Strategic Shot Across the Bow or Misstep?
On December 16, 2025, Kids2 LLC — an infant and toddler product company and holder of US7740560B2 — filed an infringement action in the Eastern District of Texas against Carter’s Inc., The William Carter Co., Carter’s Retail Inc., and Skip Hop Inc. The asserted products included the Skip Hop Explore & More 3-stage activity center, the Silver Lining Cloud, and the Discoverosity Montessori Skip Hop line — all multi-stage infant play products that Kids2 alleged fell within the scope of its patent.
Three days after filing, on December 19, 2025, Kids2 filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), terminating the action before any defendant had been served or filed an answer. Because dismissal under 41(a)(1)(A)(i) is a unilateral plaintiff right exercised before service of an answer, no court order was required. Costs and fees were allocated so that each side bears its own. The public record does not disclose whether any settlement, licensing negotiation, or other arrangement preceded the withdrawal.
A case lifespan of three days — from filing to voluntary dismissal — is notably brief even by the standards of patent suits that resolve early. The absence of defendant service suggests the dismissal may reflect a pre-litigation development such as an opening licensing discussion, a strategic recalibration, or a filing timed to establish a legal record. Because the dismissal was without prejudice, Kids2 retains the right to refile substantially the same claims, keeping the competitive pressure on the Skip Hop product lines unresolved from a patent standpoint.
Filing to Voluntary dismissal in 3 days
3 days — among the shortest-lived district court filings; closed before defendants were served
Voluntarily dismissed: what a Rule 41 exit before service means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit right
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss its action without a court order at any time before the defendant has served either an answer or a motion for summary judgment. Kids2 exercised this right on day three. Because no defendant had been served, the dismissal was purely unilateral — no judicial approval, no merits adjudication, no binding findings on the patent’s validity or scope.
No court order requiredThe prejudice distinction matters — and the record is silent on why
A dismissal without prejudice leaves the door open: Kids2 may refile the same infringement claims against the same defendants at a later date, subject to the applicable statute of limitations. A dismissal with prejudice would have barred refiling entirely. The notice here explicitly states ‘without prejudice,’ meaning the Skip Hop product lines remain under potential threat. The public record does not disclose whether any licensing discussion, demand letter response, or side agreement preceded the withdrawal.
Refiling remains possibleCarter’s and Skip Hop: no win on the merits, but costs avoided
The defendants were never served and filed no response, so there is no court finding in their favour regarding invalidity, non-infringement, or unenforceability of US7740560B2. Each side bearing its own costs means defendants incurred no fee award. However, the without-prejudice dismissal provides no legal shield against a future suit on the same patent — the infringement question remains open and the activity center product lines are still potentially exposed.
No merits ruling for defendantsUnresolved IP cloud over the Skip Hop activity center portfolio
US7740560B2 remains an active, unadjudicated patent. The rapid dismissal without prejudice is consistent with an opening move in a licensing negotiation or a tactical filing to establish a record. Competitors and retailers carrying Skip Hop activity center lines should note that no court has ruled on the patent’s scope or validity. Product teams working on multi-stage infant activity centers should monitor the status of this patent and any refiling activity closely.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly states ‘without prejudice,’ confirming this is a unilateral plaintiff withdrawal carrying no merits determination. The explicit cost-bearing language — each party to bear its own costs — forecloses any fee recovery argument. Critically, the filing confirms defendants had not been served, meaning no litigation hold, responsive pleading, or court scheduling order had been triggered. The patent’s enforceability is wholly unaffected.
US7740560B2 — Multi-Stage Infant Activity Center Design
US7740560B2 (application number US11/136158) covers a multi-stage infant activity center — a product category that allows the same unit to serve developmental needs across multiple early childhood stages. The patent was asserted against the Skip Hop Explore & More 3-stage activity center, Silver Lining Cloud, and Discoverosity Montessori line, all of which feature reconfigurable or multi-use infant play architectures. The asserted patent remains in force and has received no adverse validity ruling.
The multi-stage infant activity center market is commercially significant, with major players including Kids2, Skip Hop (owned by Carter’s), and other nursery goods brands competing on both product design and IP. A granted utility patent covering the structural or functional aspects of a 3-stage activity center creates meaningful licensing leverage over competitors whose products share the same use-case progression. With no IPR, reexamination, or litigation-based invalidity challenge having resolved against this patent, its assertion value remains intact for Kids2.
Should your product team run an FTO against US7740560B2?
Any company designing, manufacturing, importing, or retailing multi-stage infant activity centers — particularly those with reconfigurable play modes targeting different developmental stages — should treat US7740560B2 as a live risk. The patent has now been asserted against three distinct Skip Hop product lines. The without-prejudice dismissal means no court has cleared those products, let alone third-party alternatives. If your product roadmap includes an activity gym, bouncer, or play center with a staged-use architecture, a targeted FTO is warranted before launch.
PatSnap Eureka’s FTO Search Agent allows product and IP teams to map US7740560B2’s claim scope against a specific product design, identify prior art that could support design-around strategies, and monitor the patent’s legal status and any continuation filings in real time. Given the E.D. Texas venue choice and the explicit without-prejudice nature of the dismissal, early FTO work is materially less costly than defending a refiled suit.

What this case signals for the infant activity center IP landscape
A three-day patent suit with no service and no merits ruling rarely ends the story — it often starts one.
Without-prejudice dismissals are a known pre-licensing tactic
Filing and rapidly dismissing before service is a recognised method to signal enforcement intent without committing to costly litigation. For Kids2, the filing of US7740560B2 against multiple Skip Hop entities establishes a documented assertion record that can support future licensing discussions or a refiled suit. Carter’s and Skip Hop have no court ruling protecting them.
The Skip Hop product lines remain uncleared from a patent standpoint
No validity or infringement determination was made. Retailers, licensees, and product developers working with the Explore & More, Silver Lining Cloud, or Discoverosity product ranges should note that US7740560B2 has been asserted against these specific products and the dispute is unresolved. A freedom-to-operate analysis against this patent is warranted.
Kids2 v Carter’s — key questions answered
Kids2 LLC filed a patent infringement action against Carter’s Inc. and Skip Hop entities in the Eastern District of Texas on December 16, 2025, asserting US7740560B2 over Skip Hop activity center products. Three days later, Kids2 voluntarily dismissed the action without prejudice under Rule 41(a)(1)(A)(i) before any defendant was served.
A without-prejudice dismissal means no court made any finding on the merits — Carter’s and Skip Hop received no ruling of non-infringement or invalidity of US7740560B2. Kids2 retains the legal right to refile substantially the same claims. The Skip Hop Explore & More, Silver Lining Cloud, and Discoverosity product lines remain potentially exposed to future assertion.
Kids2 asserted US7740560B2 (application no. US11/136158), which covers multi-stage infant activity center technology. The patent was asserted against the Skip Hop Explore & More 3-stage activity center, the Skip Hop Silver Lining Cloud, and the Discoverosity Montessori Skip Hop line.
A rapid filing and withdrawal before service is consistent with several strategic scenarios: initiating a licensing conversation, establishing a documented assertion record, testing venue, or responding to a pre-litigation development. The public record does not disclose the reason. The without-prejudice dismissal preserves all of Kids2’s legal options for a future refiling.
Yes. A voluntary dismissal without prejudice has no effect on the underlying patent’s enforceability or validity. No court ruled on US7740560B2’s validity, scope, or whether Skip Hop products infringe it. The patent remains an active asset and Kids2 may assert it again in future proceedings.
