II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 9,101,225 - Convertible High Chair

  • Patent Identification: U.S. Patent No. 9101225, "Convertible High Chair," issued August 11, 2015.
  • The Invention Explained:
    • Problem Addressed: The patent describes a need in the art for an improved convertible high chair that is more convenient for users to convert. It specifically notes that some prior art high chairs with detachable booster seats require the booster to be coupled to a "separate base member" before it can be used on a standard chair (’225 Patent, col. 1:35-44).
    • The Patented Solution: The invention is a convertible high chair with two main components: a first child seat on a frame and a second, removable child seat (booster). The key feature is that the second child seat has a base surface configured to "stably support itself on a support surface (e.g., a standard chair) without the need to be secured to a separate component (e.g., a separate base member)" (’225 Patent, col. 1:38-44). This dual-use design, where the booster nests into the main high chair or functions as a standalone unit, is illustrated in the patent's figures (Compl. ¶17, referencing ’225 Patent, Figs. 1, 2, and 7).
    • Technical Importance: This approach enhances convenience by eliminating the need for an extra component, which simplifies the conversion process and reduces manufacturing costs (’225 Patent, col. 6:55-65).
  • Key Claims at a Glance:
    • The complaint asserts independent claim 1 and dependent claims 2-3 (Compl. ¶47).
    • Independent Claim 1 of the ’225 Patent requires:
      • A frame configured for resting on a floor;
      • A first child seat defining a first seating surface, coupled to the frame and supported above the floor;
      • A second child seat defining a second seating surface, configured for being removably coupled to the first child seat;
      • Wherein the second child seat defines a base surface configured for engaging the first seating surface when coupled, and for "resting directly on a flat support surface and thereby supporting the second child seat in a stable upright position" when decoupled (Compl. ¶19).

U.S. Patent No. 9,883,749 - Convertible High Chair

  • Patent Identification: U.S. Patent No. 9883749, "Convertible High Chair," issued February 6, 2018.
  • The Invention Explained:
    • Problem Addressed: Sharing a common specification with the ’225 Patent, the ’749 Patent addresses the same problem of inconvenient prior art convertible high chairs that require a separate base for their booster seat function (’749 Patent, col. 1:38-44; Compl. ¶15).
    • The Patented Solution: The ’749 Patent claims the invention with a focus on the structural efficiency of the booster seat's base. The claims require that the "same base portion" of the second child seat performs two distinct functions: it "both engages the first seat assembly" in the high chair configuration and "also rests directly on a flat support surface without the need for a separate support member" in the booster seat configuration (’749 Patent, Claim 1; col. 6:23-35).
    • Technical Importance: This claimed solution emphasizes the unitary and multi-functional nature of the booster seat's base, which simplifies the product's design and use (’749 Patent, col. 6:56-65).
  • Key Claims at a Glance:
    • The complaint asserts independent claim 1 and dependent claims 5 and 6 (Compl. ¶62).
    • Independent Claim 1 of the ’749 Patent requires:
      • A first seat assembly comprising a frame and a first child seat;
      • A second child seat comprising a base portion and a seatback portion;
      • Wherein the "same base portion" both engages the first seat assembly when coupled in a high chair configuration, and also rests directly on a flat support surface without a separate support member when decoupled in a booster seat configuration (Compl. ¶21).

Multi-Patent Capsule: U.S. Patent No. 10,278,513 - Convertible High Chair

  • Patent Identification: U.S. Patent No. 10278513, "Convertible High Chair," issued May 7, 2019 (Compl. ¶22).
  • Technology Synopsis: The ’513 Patent claims a convertible high chair where a second child seat is detachably coupled to a first child seat. The claims specify that a "base portion of the second child seat [is] supported over the first child seat" in the combined configuration and is configured to "rest directly on a generally flat support surface" when detached (Compl. ¶23).
  • Asserted Claims: Independent claim 1 and dependent claim 5 (Compl. ¶76).
  • Accused Features: The complaint alleges that the accused products' ability to have the booster seat rest on top of the main seat, and then be removed to rest on an adult chair, infringes the ’513 Patent (Compl. ¶¶ 79-82).

Multi-Patent Capsule: U.S. Patent No. 10,835,053 - Convertible High Chair

  • Patent Identification: U.S. Patent No. 10835053, "Convertible High Chair," issued November 17, 2020 (Compl. ¶24).
  • Technology Synopsis: The ’053 Patent claims a convertible high chair where the base surface of the second child seat is "dimensioned to nest within the first child seat" in the high chair configuration. This same base surface is also configured to provide a "stable platform" on a separate support surface without needing a separate base or support member (Compl. ¶25).
  • Asserted Claims: Independent claim 1 and dependent claim 8 (Compl. ¶90).
  • Accused Features: The infringement allegations focus on the accused products' booster seats, which are alleged to both nest within the main high chair structure and provide a stable, standalone platform when used as a booster (Compl. ¶¶ 93-96).

Multi-Patent Capsule: U.S. Patent No. 11,534,006 - Convertible High Chair

  • Patent Identification: U.S. Patent No. 11534006, "Convertible High Chair," issued December 27, 2022 (Compl. ¶26).
  • Technology Synopsis: The ’006 Patent claims a convertible high chair with a second child seat comprising an "upper portion" for supporting a child and a "lower portion" with a surface configured for resting on a flat support. The claims state that the upper and lower portions together are configured for "detachably coupling to the first child seat" (Compl. ¶27).
  • Asserted Claims: Independent claim 1 (Compl. ¶104).
  • Accused Features: The complaint accuses the entire convertible functionality of the accused products, where the second child seat couples to the first and can also stand alone on a flat surface (Compl. ¶¶ 107-109).

Multi-Patent Capsule: U.S. Patent No. 11,653,771 - Booster Seat for Convertible High Chair

  • Patent Identification: U.S. Patent No. 11653771, "Booster Seat for Convertible High Chair," issued May 23, 2023 (Compl. ¶28).
  • Technology Synopsis: Unlike the other patents-in-suit that claim the entire high chair, the ’771 Patent claims the booster seat component itself. The claims describe a child seat configured for removable coupling to a high chair assembly, featuring a base portion that can rest on a flat surface and that includes "recesses configured to receive corresponding shoulder portions of the high chair seat assembly" (Compl. ¶29).
  • Asserted Claims: Independent claims 1 and 21 (Compl. ¶¶ 117, 124).
  • Accused Features: The complaint accuses the booster seats of the accused products, alleging they are designed to fit onto the main high chair and also function independently (Compl. ¶¶ 119-128).

III. The Accused Instrumentality

  • Product Identification: The complaint names the Maxi Cosi Moa 8-in-1 High Chair, the Monbebe Fusion Reclining Highchair, and the Safety 1st Grow and Go Rotating High Chair (collectively, the "Moa/Fusion/Grow High Chairs") (Compl. ¶47). The Maxi Cosi Minla 6-in-1 High Chair is also accused of infringing the ’771 patent (Compl. ¶117).
  • Functionality and Market Context: The accused products are multi-functional high chairs sold by Defendant Dorel. The complaint alleges these products operate in multiple modes, including as a full high chair and as a standalone booster seat that can be detached and placed on an adult dining chair (Compl. ¶¶ 50-52). The complaint provides photographic evidence showing the accused products in these different configurations. For example, a set of photographs shows the accused Moa/Fusion/Grow High Chairs assembled as high chairs with frames resting on the floor (Compl. p. 17). Defendant sells these products through its own brand websites and major third-party retailers such as Amazon and Walmart (Compl. ¶¶ 38-44).

IV. Analysis of Infringement Allegations

U.S. Patent No. 9,101,225 Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
a convertible children's high chair comprising: a frame configured for resting on a floor; The accused products are convertible high chairs with frames that rest on the floor. ¶50 col. 3:20-22
a first child seat defining a first seating surface, the first child seat being coupled to the frame and supported above the floor; and The accused products have a main child seat that is attached to the frame above the floor. A photograph shows the main seat component of the accused chairs detached from the booster seat (Compl. p. 18). ¶51 col. 3:37-41
a second child seat defining a second seating surface, the second child seat configured for being removably coupled to the first child seat; The accused products include a second, smaller seat (booster) that is removably coupled to the first seat. ¶52 col. 2:50-54
wherein the second child seat defines a base surface configured for engaging the first seating surface... and for resting directly on a flat support surface and thereby supporting the second child seat in a stable upright position on the flat support surface when the second child seat is decoupled from the first child seat. The complaint alleges the base of the second seat both engages the first seat and can be decoupled to rest directly and stably on a flat surface, such as an adult chair. A series of photographs shows the accused booster seats resting on adult dining chairs to illustrate this functionality (Compl. p. 19). ¶52 col. 2:55-60

U.S. Patent No. 9,883,749 Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
a first seat assembly comprising a frame configured for resting on a floor, and a first child seat attached to the frame and supported above the floor by the frame; and The accused products are comprised of a first seat assembly with a frame and a main child seat supported by it. ¶¶65-66 col. 3:8-15
a second child seat comprising a base portion and a seatback portion, The accused products' booster seats are alleged to have a base portion and a seatback portion. ¶67 col. 4:1-6
wherein the same base portion both engages the first seat assembly when the second child seat is coupled to the first seat assembly in a high chair configuration, and also rests directly on a flat support surface without the need for a separate support member... to independently support the second child seat in a stable upright position... in a booster seat configuration. The complaint alleges that the base of the accused booster seats performs a dual function: it engages the main high chair and also serves as the direct support surface when used as a standalone booster. Photographs show the accused booster seats placed on adult chairs, allegedly demonstrating this dual-function base (Compl. p. 24). ¶67 col. 6:23-35
  • Identified Points of Contention:
    • Scope Questions: A central dispute may arise over the construction of key claim terms like "resting directly on a flat support surface" ('225 Patent) and "same base portion" ('749 Patent). The question for the court will be whether these terms, in the context of the patent specification, encompass the specific designs of the accused products' booster seats, or if there are material differences that place them outside the claim scope.
    • Technical Questions: A key technical question is whether the base of the accused booster seats actually performs the dual functions as claimed. For instance, regarding the '749 Patent, what evidence does the complaint provide that the features of the booster's base that "engage" the first seat assembly are part of the "same base portion" that "rests directly" on a chair? The complaint relies on photographs, and the litigation will likely involve a more detailed structural and functional comparison.

V. Key Claim Terms for Construction

  • The Term: "resting directly on a flat support surface" (’225 Patent, Claim 1)

  • Context and Importance: This term is critical because it captures the patent's primary point of novelty over prior art that allegedly required a separate, intermediate base for the booster seat. The outcome of the infringement analysis for the ’225 Patent may depend heavily on whether the accused products are found to "rest directly" on a chair.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The patent's background distinguishes the invention from prior art that "must be coupled to a separate base member" (’225 Patent, col. 1:35-38). A party could argue that "directly" should be interpreted in this context to mean "without a separate, attachable base piece," which could still permit the presence of integral feet or minor contours on the bottom of the booster.
    • Evidence for a Narrower Interpretation: The claim also requires resting on a "flat support surface," and the specification describes the base surface as "substantially flat" (col. 4:57-58). A party could argue that "resting directly" requires a near-complete planar contact and that any significant structural features on the base, such as feet, would mean the booster is not resting "directly" on the flat surface but rather on those features.
  • The Term: "same base portion" (’749 Patent, Claim 1)

  • Context and Importance: This term is central to the infringement theory for the ’749 Patent, which claims a specific efficiency where one structural element performs two different functions. Practitioners may focus on this term because if different features on the booster's underside are used for coupling versus for standing, an argument of non-infringement could be made.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The specification generally describes the "second child seat 20" and its "bottom base surface 30" as a single unit (’749 Patent, col. 4:54-55). A party could argue that the entire underside structure constitutes the "base portion," and because this single unit performs both functions (engaging and resting), it meets the claim limitation.
    • Evidence for a Narrower Interpretation: The claim requires the "same base portion" to both engage and rest. A party could argue this requires the very same surface area to perform both functions. If, for example, the booster uses specific clips or hooks to engage the main seat but rests on a different flat area of its bottom, it could be argued that different parts of the base portion are performing the two functions, not the "same base portion."

VI. Other Allegations

  • Indirect Infringement: The complaint alleges that Dorel induces infringement by selling the accused products to customers, who then assemble and use them in an infringing manner. It also alleges contributory infringement by selling components of the products (Compl. ¶¶ 48, 63, 77).
  • Willful Infringement: The complaint alleges that Dorel's infringement has been willful and deliberate. This allegation is based on Dorel having gained actual knowledge of the asserted patents and its alleged infringement "at least by the date of pre-suit negotiations which took place on May 15, 2024" (Compl. ¶¶ 56, 70, 84). The complaint also alleges willful blindness for conduct prior to that date.

VII. Analyst’s Conclusion: Key Questions for the Case

The resolution of this case may turn on the following key questions:

  • A core issue will be one of definitional scope: Can the phrase "resting directly on a flat support surface," intended to distinguish from prior art needing a separate base, be construed to read on the specific bottom-surface geometry of the accused booster seats? The court's interpretation of "directly" will be pivotal.
  • A second central question will be one of structural and functional identity: For the ’749 Patent, does the "same base portion" of the accused booster seats perform both the function of engaging the main high chair and the function of resting on a flat surface, or are these functions performed by distinct features of the booster's base?
  • A key question for damages will be one of scienter and willfulness: Did Dorel's alleged conduct, particularly its sales after the May 15, 2024 pre-suit negotiations, rise to the level of willful infringement, which could expose it to the risk of enhanced damages?
