Summer Infant USA Inc v. TOMY Intl Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Summer Infant (USA), Inc. (Delaware)
- Defendant: TOMY International, Inc. (Delaware)
- Plaintiff’s Counsel: ADLER POLLOCK & SHEEHAN P.C.
- Case Identification: 1:17-cv-00549, D.R.I., 11/27/2017
- Venue Allegations: Venue is asserted based on TOMY’s regular business conduct within the judicial district and because a substantial part of the events giving rise to the action, namely the dispute over product sales, allegedly occurred there.
- Core Dispute: Plaintiff seeks a declaratory judgment that its baby bathtub product does not infringe Defendant's patent related to tubs for bathing infants and toddlers.
- Technical Context: The technology concerns juvenile bath products, specifically single-unit bathtubs designed to accommodate both reclining infants and seated toddlers.
- Key Procedural History: The complaint was filed in response to a cease and desist letter from TOMY dated November 14, 2017, which asserted that the Plaintiff's product infringes the patent-in-suit. This letter is cited as the basis for the "actual controversy" required for a declaratory judgment action.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,578,209 - Tubs for Bathing Infants and Toddlers
- Patent Identification: U.S. Patent No. 6,578,209, Tubs for Bathing Infants and Toddlers, issued June 17, 2003.
The Invention Explained
- Problem Addressed: The patent background describes the challenge of bathing children as they grow from infants, who must be bathed in a reclined position, to toddlers, who prefer to sit erect. It also notes commercial challenges related to creating tubs that are convenient, conserve water, and can be efficiently stored and shipped (’209 Patent, col. 1:11-29).
- The Patented Solution: The invention is a single molded plastic tub with opposing back rests at different angles of inclination. A steeply reclined back rest supports an infant, while a more upright back rest supports a seated toddler (’209 Patent, col. 1:35-44). The tub's body is designed with a specific shape that allows identical tubs to "nest" closely together, which reduces the space needed for shipping and retail display (’209 Patent, col. 2:1-11).
- Technical Importance: This "2-in-1" design offers a single product that adapts to a child’s developmental stages, while the nesting feature addresses practical logistics and costs for manufacturers and retailers (’209 Patent, col. 3:56-59).
Key Claims at a Glance
- The complaint seeks a declaratory judgment of non-infringement for all claims of the '209 patent, focusing on a limitation it alleges is common to all independent claims (Compl. ¶5). The independent claims appear to be claims 1, 22, 23, and 30.
- Independent Claim 1, a representative claim, includes these essential elements:
- A molded plastic tub body with an upper rim and a bathing basin.
- Opposing side walls forming a first back rest at a first incline angle and a second back rest at a second incline angle.
- A bottom surface with "two seating surfaces disposed at differing inclinations and extending from respective back rests to distal edges joined at a bottom surface apex."
- A body with matching upper and lower surfaces enabling the tub to nest within an identical tub.
III. The Accused Instrumentality
Product Identification
- The "Comfy Clean Deluxe Newborn to Toddler Tub" (the "Accused Product") (Compl. ¶3).
Functionality and Market Context
- The Accused Product is described as a competitive product to TOMY’s own "TOMY Tub" and is a plastic bathtub for infants and toddlers (Compl. ¶¶2-3).
- The complaint’s primary technical description of the Accused Product is a negative one, asserting that it "does not have 'two seating surfaces disposed at differing inclinations and extending from respective back rests to distal edges joined at a bottom surface apex'" (Compl. ¶5).
- The complaint provides a visual of the Accused Product, which depicts a single-piece molded plastic tub with a continuous, curved interior surface and a separate, removable mesh sling insert for supporting an infant (Compl. p. 2, figure).
IV. Analysis of Infringement Allegations
The complaint seeks a declaratory judgment of non-infringement. The analysis below summarizes the plaintiff's (Summer Infant's) non-infringement position as articulated in the complaint.
’209 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Non-Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a first of the opposing side walls extending at a first incline angle with respect to the rim, and a second, opposite one of the opposing side walls extending at a second incline angle with respect to the rim, the first and second inclined side walls forming first and second back rests for children seated in the tub in different orientations; | The complaint does not provide sufficient detail for analysis of this element. | col. 6:35-40 | |
| the bottom surface having two seating surfaces disposed at differing inclinations and extending from respective back rests to distal edges joined at a bottom surface apex spaced from either end of the basin, each seating surface forming, together with a respective one of the back rests, an inclined seat; | The complaint alleges the Accused Product does not have this feature. It asserts the product lacks two distinct seating surfaces joined at a bottom surface apex. | ¶5 | col. 6:40-47 |
| wherein the body has a nominal thickness and upper and lower surfaces having matching shape across an overall extent of the tub so as to enable the tub to nest within an identical tub with a nesting space differential of less than about two inches (five centimeters). | The complaint does not provide sufficient detail for analysis of this element. | col. 6:48-53 |
Identified Points of Contention
- Technical Question: The central factual dispute raised by the complaint is whether the Accused Product's internal structure embodies the claimed "two seating surfaces... joined at a bottom surface apex." The complaint's visual evidence suggests a single, continuous curve rather than two distinct surfaces meeting at an apex (Compl. p. 2, figure).
- Scope Question: The case may turn on the construction of the term "bottom surface apex." A key question is whether this term requires a distinct, sharp, V-shaped junction as depicted in the patent’s figures (e.g., ’209 Patent, Fig. 13, element 66), or if it could be interpreted more broadly to cover a structure that functionally provides two seating areas, even if joined by a curve.
V. Key Claim Terms for Construction
- The Term: "two seating surfaces disposed at differing inclinations and extending from respective back rests to distal edges joined at a bottom surface apex"
- Context and Importance: This term is presented by the plaintiff as dispositive for the entire case. The plaintiff's non-infringement theory rests on the argument that its product lacks this specific structure, and that the limitation is required by every independent claim of the '209 patent (Compl. ¶5).
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patentee (TOMY) may argue that the term does not require a literal geometric point. The specification describes the seating surfaces as "joined by a central bottom surface portion that rises from the distal edge of one of the seating surfaces to the distal edge of the other" (’209 Patent, col. 2:64-67). This language could potentially support a construction that is not limited to a sharp, angular apex.
- Evidence for a Narrower Interpretation: The declaratory judgment plaintiff (Summer Infant) will likely argue for a narrow construction. The use of the word "apex" itself suggests a vertex or peak. Furthermore, the preferred embodiment shown in Figure 13 clearly illustrates two distinct flat surfaces (64, 70) meeting at a defined apex (66), rather than a smooth, continuous curve (’209 Patent, col. 5:42-55). This figure strongly supports a construction requiring a specific, molded V-shaped geometry.
VI. Other Allegations
- Indirect Infringement: The complaint includes a blanket denial of any direct or indirect infringement but does not provide specific facts relating to inducement or contributory infringement (Compl. ¶19).
- Willful Infringement: Willfulness is not alleged by the plaintiff. However, the complaint establishes that the defendant provided pre-suit notice of alleged infringement via its cease and desist letter of November 14, 2017 (Compl. ¶4, ¶17). This fact would become central to any future willfulness analysis if infringement were to be found.
VII. Analyst’s Conclusion: Key Questions for the Case
This declaratory judgment action appears to be a focused challenge to the scope of the ’209 patent. The case will likely turn on the resolution of two primary questions:
A core issue will be one of claim construction: How narrowly must the limitation "two seating surfaces... joined at a bottom surface apex" be defined? Will the court require a distinct, molded geometric apex as shown in the patent's figures, or can the claim language be construed to read on a more generally curved bottom surface that provides two functionally different seating areas?
A key evidentiary question will be one of factual comparison: Once the claim is construed, does the physical geometry of the Summer Infant "Comfy Clean Deluxe" tub meet that definition? The plaintiff's case is premised on the assertion of a clear structural mismatch.
