1:24-cv-22149
Tushbaby Inc v. Fleerose
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Tushbaby, Inc. (California)
- Defendant: Fleerose (China)
- Plaintiff’s Counsel: Boies Schiller Flexner LLP
- Case Identification: 1:24-cv-22149, S.D. Fla., 06/04/2024
- Venue Allegations: Plaintiff Tushbaby alleges venue is proper because Defendant Fleerose conducts significant business in the district, including targeting consumers with products allegedly covered by the patent-in-suit. Plaintiff also notes that Fleerose made its infringement allegations in the context of other judicial proceedings within the district.
- Core Dispute: Plaintiff seeks a declaratory judgment that its "Tushbaby Carrier" product does not infringe Defendant's design patent for a hip seat baby carrier, and/or that the patent is invalid.
- Technical Context: The dispute centers on the ornamental design of hip seat baby carriers, a consumer product category focused on providing ergonomic support for carrying infants and toddlers.
- Key Procedural History: This declaratory judgment action arises from accusations of infringement made by Defendant Fleerose against Plaintiff Tushbaby during separate, ongoing lawsuits in the same district concerning trade dress and copyright. Tushbaby's central invalidity argument is that its own Tushbaby Carrier product, which it has sold since 2018, constitutes invalidating prior art against Fleerose's patent, which was filed for in 2023.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D1,024,542 - "Hip seat baby carrier"
The Invention Explained
- Problem Addressed: The complaint does not detail a specific problem, as is typical for design patents which protect ornamental appearance rather than functional utility. The subject matter is an article of manufacture for carrying a child (D’542 Patent, Title).
- The Patented Solution: The patent claims the ornamental design for a hip seat baby carrier, as depicted in its figures (D’542 Patent, Claim, Figs. 1-11). The design features a main body with a padded seat portion on top, an adjustable waist strap, and various pockets and attachment points. The overall visual impression is defined by the specific shapes, contours, and arrangement of these elements, including the texture shown on a side pocket and the pattern of raised dots on the seat surface (D’542 Patent, Figs. 1, 3, 11).
- Technical Importance: The complaint does not comment on the technical importance of the design; in the market for baby carriers, distinct ornamental designs serve to differentiate brands and appeal to consumer aesthetic preferences.
Key Claims at a Glance
- The patent contains a single claim: "The ornamental design for a hip seat baby carrier, as shown and described" (D’542 Patent, Claim).
- The scope of this claim is defined by the visual appearance of the carrier as illustrated in the patent's eleven figures.
III. The Accused Instrumentality
Product Identification
The "Tushbaby Carrier" (Compl. ¶2).
Functionality and Market Context
The complaint describes the Tushbaby Carrier as a proprietary product that "provides for the carrying of young, with storage pockets" (Compl. ¶5). Plaintiff Tushbaby asserts it is a "leading infant carrier manufacturer and distributor" and that its product has been marketed and sold since at least 2018 (Compl. ¶¶4, 7). The complaint includes several images of the Tushbaby Carrier, showing a fabric-covered hip seat with an integrated waistband and various storage compartments. One such visual shows the product in use, worn around a person's waist to support a small child (Compl. p. 2).
IV. Analysis of Infringement Allegations
The complaint is for a declaratory judgment of non-infringement and invalidity, filed by the accused infringer, Tushbaby. The infringement allegations were made by the patentee, Fleerose, in separate legal proceedings (Compl. ¶¶13-15).
The central dispute, as framed by Tushbaby, is not a typical element-by-element infringement analysis. For design patents, infringement is determined by the "ordinary observer" test, which asks whether an ordinary observer, familiar with the prior art, would be deceived into purchasing the accused product believing it to be the patented design.
Tushbaby's complaint pivots these infringement accusations into a direct challenge to the patent's validity. The core allegation is that if the D’542 patent's design is considered substantially the same as the Tushbaby Carrier for infringement purposes, then the patent must be invalid as anticipated or obvious under 35 U.S.C. §§ 102 and 103 (Compl. ¶¶23, 28). This is because Tushbaby has "publicized and sold its proprietary Carrier" since 2018, approximately five years before the D’542 patent's application was filed on September 3, 2023 (Compl. ¶21). The complaint provides evidence of these prior sales and public disclosures, including archived webpages from 2018 (Compl. ¶7, Exs. 2-3).
- Identified Points of Contention:
- Invalidity via On-Sale Bar: The primary question raised by the complaint is whether the Tushbaby Carrier, sold and publicly known since 2018, constitutes prior art that anticipates or renders obvious the design claimed in the D’542 patent. The court will need to compare the pre-2023 Tushbaby Carrier with the patented design.
- Scope Questions: The case presents a logical dilemma for the patentee, Fleerose. To prove infringement, Fleerose must argue that its patented design and the Tushbaby Carrier are substantially the same. However, as Tushbaby argues, this very assertion may support the conclusion that Tushbaby's own earlier product invalidates the patent.
V. Other Allegations
The complaint does not contain allegations of indirect or willful infringement. Plaintiff Tushbaby does, however, request that the court find the case "exceptional under 35 U.S.C. § 285" and award attorneys' fees, though the specific factual basis for this request is not detailed beyond the context of the overall dispute (Compl. p. 8).
VI. Analyst’s Conclusion: Key Questions for the Case
The resolution of this declaratory judgment action will likely depend on the court’s answers to two interdependent questions:
A question of invalidity: Does the Tushbaby Carrier, as sold and publicly disclosed since 2018, render the ornamental design claimed in the D’542 patent invalid under 35 U.S.C. § 102 (anticipation) or § 103 (obviousness)? The complaint’s factual allegations and exhibits regarding Tushbaby's long-standing product appear to make this the central issue.
A question of infringement scope: If the D’542 patent is deemed valid over Tushbaby's prior product, are the two designs "substantially the same" in the eyes of an ordinary observer? The court will have to determine if there are sufficient ornamental differences between the patented design and the accused Tushbaby Carrier to avoid a finding of infringement.
