II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,053,868 - "Floor panel and floor covering consisting of a plurality of such floor panels"
- Patent Identification: U.S. Patent No. 10,053,868, "Floor panel and floor covering consisting of a plurality of such floor panels," issued August 21, 2018.
The Invention Explained
- Problem Addressed: The patent seeks to overcome drawbacks of prior art flooring panel connection systems that required a "tilting movement" for installation. This movement could exert damaging forces on the panels and required significant space, making it difficult to lay flooring near walls or under radiators (ʼ868 Patent, col. 1:44-53).
- The Patented Solution: The invention is a floor panel with complementary, resilient coupling parts on opposite edges. These parts, comprising a specific geometry of tongues, flanks, and grooves, are designed to elastically deform when one panel is pushed downward or linearly into another. After engagement, the parts "move back resiliently to the original position," creating a durable, locked connection without requiring a tilting motion (ʼ868 Patent, col. 2:40-49). This "push-to-lock" mechanism is achieved through the interaction of precisely shaped aligning edges and locking elements on the coupling parts ('868 Patent, Abstract).
- Technical Importance: This approach allows for a simpler, stronger, and more reliable installation method that is less likely to damage the product and can be performed in confined spaces ('868 Patent, col. 1:54-col. 2:2).
Key Claims at a Glance
- The complaint asserts independent claims 1, 2, and 3 ('868 Patent, col. 17:1-col. 19:2; Compl. ¶15).
- Independent Claim 1: The broadest asserted claim recites a floor panel with:
- A central core.
- A first resilient coupling part on one edge, comprising a single upward tongue, an upward flank, and an upward groove.
- A second resilient coupling part on the opposite edge, comprising a single downward tongue, a downward flank, and a downward groove.
- Specific geometries for the tongue sides, including surfaces that form an "upward aligning edge" and a "downward aligning edge."
- An "upper side of the upward tongue" that runs "inclining downward" and a corresponding upward-inclining "upper side of the downward groove."
- A "locking element" on a side of the downward tongue and a "counter-locking element" on the upward flank, which cooperate to lock panels together.
- Independent Claim 2: This claim is structurally similar to claim 1 but omits the limitation requiring the corresponding inclining surfaces on the upward tongue and downward groove.
- Independent Claim 3: This claim adds specificity to the upward tongue, requiring the side facing the upward flank to include a "first portion" and a "second portion" with defined geometries and orientations.
III. The Accused Instrumentality
Product Identification
- The "GOLDEN AROWANA®" collection of luxury vinyl plank flooring, including the "GOLDEN AROWANA® HDPC® Rigid Core Waterproof Planks" (Compl. ¶16).
Functionality and Market Context
- The complaint alleges the accused products incorporate a "patented push down" lock system marketed by Unilin Technologies as "UNIPUSH®" (Compl. ¶17). This mechanism is allegedly used on the short sides of the flooring planks, allowing them to be connected without a traditional angling or folding motion (Compl. ¶24).
- The products are sold by Defendant Wellmade through various retailers, including Defendant Costco (Compl. ¶16). A photograph in the complaint shows a cross-section of the accused locking mechanism (Compl. p. 5, Image).

|---|---|---|---|
| A floor panel, comprising: a centrally located core provided with an upper side and a lower side, | The GOLDEN AROWANA® product is a floor panel with a centrally located core. | ¶25 | col. 17:1-2 |
| at least one first resilient coupling part and second resilient coupling part connected respectively to opposite edges of the core, | The product includes coupling parts on opposite edges of the core, identified as a fold-down system on the long sides and the accused Unilin UNIPUSH® mechanism on the short sides. | ¶24, ¶25 | col. 17:3-5 |

A photo circles these components. | ¶30 | col. 17:42-48 |
- Identified Points of Contention:
- Scope Questions: The claims require a "resilient coupling part." The patent describes this resiliency in terms of elastic deformation and pivoting that allows the grooves to temporarily widen ('868 Patent, col. 4:9-11). The infringement analysis may turn on whether the accused "UNIPUSH®" system achieves its lock through this specific claimed resiliency or via a different mechanical interaction that falls outside the scope of "resilient" as defined by the patent.
- Technical Questions: A primary question will be one of locational precision. Claim 1 requires the "locking element" to be on the "side of the downward tongue facing away from the downward flank." The complaint alleges this configuration (Compl. ¶30), supported by a photo circling the relevant area (Compl. p. 16, Image). However, a defendant may argue that the actual locking feature (e.g., a bulge or recess) on the accused product is technically part of the downward flank, not the downward tongue, thereby creating a mismatch with the explicit language of the claim.
V. Key Claim Terms for Construction
The Term: "resilient coupling part"
- Context and Importance: This term is fundamental to the invention. The theory of infringement rests on the accused product’s parts being "resilient" in the manner claimed. Practitioners may focus on this term because if the accused product's coupling parts are found to be rigid or to lock via a non-resilient mechanism, the infringement case could fail.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification states that locking is "realized by deforming the first coupling part and/or the second coupling part relative to the core" ('868 Patent, col. 2:61-64), suggesting that any part that elastically deforms to achieve a connection could be considered "resilient."
- Evidence for a Narrower Interpretation: The patent describes a specific embodiment where "the end part is adapted to move resiliently (elastically) in a direction enclosing an angle...with a plane formed by the core" ('868 Patent, col. 3:62-65). A defendant could argue this language limits "resilient" to a specific pivoting action, rather than general material elasticity.
The Term: "locking element"
- Context and Importance: The precise location and structure of the "locking element" is a critical limitation. Claim 1 places it on the "downward tongue," while the "counter-locking element" is on the "upward flank." This distinction will be central to the infringement analysis.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes the element functionally, noting it can be a "protruding (outward bulging) or recessed (inward bulging) edge deformation" ('868 Patent, col. 3:5-7), which supports a broad structural definition.
- Evidence for a Narrower Interpretation: The patent also states the locking element is "connected substantially rigidly to...the upward tongue" ('868 Patent, col. 2:56-59). A party could argue this disfavors an interpretation where the locking element is a flexible tab or is structurally indistinct from the tongue itself. The specific structures in the figures (e.g., bulge 44 on flank 42 and recess 49 on flank 47 in Fig. 6) may be used to argue for a narrower definition tied to the preferred embodiments.
VI. Other Allegations
The complaint alleges direct infringement under 35 U.S.C. § 271(a) (Compl. ¶33). It does not contain separate counts for indirect or willful infringement, nor does it allege specific facts to support pre-suit knowledge of the patent.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "resilient coupling part," which the patent links to specific elastic deformation and pivoting mechanisms, be construed to read on the accused UNIPUSH® system? The case may depend on whether the accused product's function aligns with the specific type of resiliency described and claimed.
- A key evidentiary question will be one of structural precision: does the accused product's locking mechanism possess a "locking element" that is located on the "side of the downward tongue," as strictly required by Claim 1, or is it located on an adjacent surface in a way that falls outside the literal scope of the claim? The resolution of this factual and technical question will be critical for determining infringement.
