Case Timeline

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

U.S. Patent No. 10,272,934 - “Multi-terrain multi-purpose insulated container” (Issued Apr. 30, 2019)

The Invention Explained

• Problem Addressed: The patent's background describes conventional insulated coolers as "archaic and riddled with inconveniences," noting they are difficult to transport over uneven terrain because their wheels are too small or, if made larger, they either increase the cooler's overall size or reduce internal storage capacity (’934 Patent, col. 1:39-54).
• The Patented Solution: The invention is a portable container with a unique body geometry and large wheels designed to improve off-road transport. The body features walls of differing heights, which creates a "gradient" on the underside, and large wheels are integrated to increase ground clearance without compromising the container's core function. This design aims to combine the utility of a cooler with the rugged mobility of a wagon (’934 Patent, col. 2:1-23).
• Technical Importance: The described solution seeks to enhance the portability of heavy, fully-loaded coolers in outdoor environments where paved surfaces are unavailable, such as beaches, campsites, and job sites (’934 Patent, col. 1:28-34, 55-58).

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶20).
• The essential elements of independent claim 1 include:
  • a body with a plurality of walls forming an enclosure and a lid;
  • a first wall and an oppositely disposed second wall, where the first wall's height is greater than the second wall's height;
  • a base and a third wall extending from the base to the second wall, with the third wall having a "first gradient" due to the height differential;
  • a "junction" affixed to a first side wall, which has a "second gradient" with respect to the base; and
  • a first and second wheel positioned adjacent to the first and second side walls, respectively.
• The complaint reserves the right to assert additional claims (Compl. ¶26).

U.S. Patent No. D881,673 - “Handle” (Issued Apr. 21, 2020)

The Invention Explained

• Problem Addressed: Design patents protect ornamentation, not function, and therefore do not articulate a technical problem.
• The Patented Solution: The patent claims the ornamental design for a handle. The design, as shown in the solid lines of the figures, consists of a specific configuration of two vertical legs joined by two horizontal, transverse bars. The lower transverse bar includes two cylindrical grip portions extending outward (’673 Patent, Figs. 1-5). The broken lines in the figures illustrate the environment (e.g., the cooler body) and form no part of the claimed design (’673 Patent, Description).

Key Claims at a Glance

• Design patents contain a single claim for the ornamental design as shown and described in the drawings (Compl. ¶28; ’673 Patent, Claim).
• The essential elements are the visual characteristics of the handle depicted in the patent's figures, including the arrangement, shape, and proportions of its constituent bars and grips.

Multi-Patent Capsule

• Patent Identification: U.S. Patent No. D893,979, “Handle,” Issued Aug. 25, 2020.
• Technology Synopsis: This design patent, a continuation of the application for the ’673 Patent, claims the ornamental design for a handle. The claimed design consists of the specific visual appearance of the handle as depicted in the patent's figures, which show a structure of vertical legs and transverse bars (’979 Patent, Claim, Figs. 1-5).
• Asserted Claims: The single claim for the ornamental design as shown and described (Compl. ¶36).
• Accused Features: The handle on Defendant’s coolers is accused of infringing the claimed ornamental design (Compl. ¶¶ 18, 36).

III. The Accused Instrumentality

• Product Identification: The accused products are "Kong Cooler's coolers, including but not limited to Kong's 50 Quart Cooler with Wheels" (Compl. ¶18).
• Functionality and Market Context: The complaint identifies the accused products as wheeled, insulated containers marketed and sold by the Defendant in the United States (Compl. ¶¶ 4, 18). The infringement allegations focus on the physical structure of the coolers, including the cooler body, wheels, and handle assembly, as embodying the patented utility and design features (Compl. ¶¶ 20, 28, 36).

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references, but does not include, claim chart exhibits that purportedly detail the infringement of each patent-in-suit. Lacking these exhibits, the infringement theories are summarized below based on the complaint's narrative allegations.

• '934 Patent Infringement Allegations
  The complaint alleges that the Accused Products directly infringe at least Claim 1 of the ’934 Patent (Compl. ¶20). It states that an attached claim chart (Exhibit D) describes this infringement, but the exhibit was not filed with the complaint (Compl. ¶26). The narrative theory is that the physical construction of Defendant's wheeled coolers embodies the claimed apparatus, including the specified arrangement of walls of differing heights, a base, a "third wall" with a "first gradient," a "junction" with a "second gradient," and wheels (Compl. ¶¶ 18, 20).

• '673 Patent Infringement Allegations
  The complaint alleges that the Accused Products infringe the single claim of the ’673 design patent (Compl. ¶28). It references an explanatory claim chart (Exhibit E) that was not included with the filing (Compl. ¶34). The infringement theory posits that the ornamental handle design of the Accused Products is substantially the same as the design claimed in the ’673 Patent in the eyes of an ordinary observer (Compl. ¶28).

• Identified Points of Contention:

  • Scope Questions: A central dispute for the '934 Patent will involve claim construction. For example, whether the molded contours of the accused cooler body constitute a "junction" having a "second gradient with respect to the base," as the claim requires, raises a question of definitional scope.
  • Technical Questions: For the '934 Patent, a key factual question is whether the geometry of the accused cooler meets the specific structural limitations of Claim 1, such as the required height differential between the "first wall" and "second wall" and the resulting "first gradient" on the "third wall."

V. Key Claim Terms for Construction

• The Term: "junction" (’934 Patent, Claim 1)

  • Context and Importance: This term is not standard in the art of coolers and is a key structural element of Claim 1. Its construction will be critical for determining whether the accused product, which has a molded plastic contours, infringes. Practitioners may focus on this term because its interpretation could either limit the claim to a distinct, attached component or allow it to read on an integral, molded feature of the cooler body.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification describes a "junction (150)" simply as the location where the "first side wall (130) and the front wall (140) meet" (’934 Patent, col. 4:3-5), which could support construing it as any corner or intersection of surfaces.
    • Evidence for a Narrower Interpretation: Claim 3, which depends from claim 1, specifies the junction is "configured to receive a tow bar bracket." Furthermore, Figure 5 depicts the junction as a specific bracket (550) for holding a tow bar (’934 Patent, Fig. 5; col. 6:50-54). This may support a narrower construction requiring a structure with a specific function beyond merely being a corner.

• The Term: "gradient" (’934 Patent, Claim 1)

  • Context and Importance: Claim 1 requires both a "first gradient" on the "third wall" and a "second gradient" on the "junction." The meaning of this term will determine whether the general sloped surfaces of the accused cooler satisfy these limitations.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification explains that the "gradient" is caused by "the differential between the heights of the first wall and the second wall" (’934 Patent, col. 2:10-13), suggesting any resulting sloped surface meets the definition.
    • Evidence for a Narrower Interpretation: The figures consistently depict the gradients (e.g., element 180 in Fig. 1) as distinct, relatively planar, angled surfaces, not as gentle curves or tapers (’934 Patent, Fig. 1). A party could argue this supports a narrower definition requiring a more defined, linear slope.

VI. Other Allegations

• Indirect Infringement: The infringement counts in the complaint exclusively allege direct infringement under 35 U.S.C. § 271(a) (Compl. ¶¶ 20, 28, 36). The complaint does not plead specific facts to support claims for either induced or contributory infringement.
• Willful Infringement: The complaint alleges that Defendant "made no attempt to design around the claims" and lacked a "reasonable basis for believing that the claims...were invalid" (Compl. ¶¶ 21-22, 29-30, 37-38). The complaint does not allege pre-suit knowledge of the patents. This suggests the willfulness allegation is predicated on knowledge gained from the filing of the lawsuit itself, raising the possibility of a post-suit willfulness claim.

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

1. A core issue will be one of structural correspondence: Does the physical geometry of the accused cooler body map onto the specific, multi-part structural definitions recited in Claim 1 of the '934 utility patent, particularly the claimed "junction" and "gradient" features?
2. A second central issue will be one of ornamental similarity: For the two design patents, does the overall visual appearance of the accused cooler's handle create the same impression as the claimed designs in the mind of an ordinary observer, or are the differences sufficient to avoid infringement?
3. A key evidentiary question will be the content of the missing exhibits: The infringement allegations for all three patents rely on claim charts (Exhibits D, E, and F) that were referenced but not filed. The detailed, element-by-element comparisons within these forthcoming documents will be critical in defining the precise technical and legal battlegrounds of the case.
