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

U.S. Patent No. 9,035,180 - "Powered Cover Plate," Issued May 19, 2015

The Invention Explained

  • Problem Addressed: The patent describes the difficulty of adding functionality like nightlights or USB chargers to existing electrical outlets. Prior solutions often required complex wiring, were bulky, or blocked access to the outlet receptacles themselves (’180 Patent, col. 1:19-33).
  • The Patented Solution: The invention is a cover plate with built-in electrical components that draws power through prongs designed to make contact with the screw terminals located on the sides of a standard electrical receptacle. This design allows the cover plate to be powered without requiring any wiring by the user and while keeping the main outlet receptacles unobstructed (’180 Patent, col. 2:1-12; Fig. 4).
  • Technical Importance: This approach provides a "plug-and-play" solution for enhancing standard electrical outlets, making it simple for consumers to add features like pathway lighting without hiring an electrician or sacrificing outlet availability (Compl. ¶11).

Key Claims at a Glance

  • The complaint asserts independent claim 11 (’180 Patent, col. 8:16-29; Compl. ¶36).
  • The essential elements of independent claim 11 are:
    • An active cover plate for an electrical receptacle having a body and screw terminals.
    • A front plate with one or more apertures for the receptacle.
    • An electrical load within the cover plate.
    • Prongs configured to extend between the body of the electrical receptacle and the sides of an electrical receptacle box.
    • The prongs are further configured to contact the screw terminals to provide power from the receptacle to the electrical load.
  • The complaint reserves the right to assert claims that depend from claim 11 (Compl. ¶36).

U.S. Patent No. 9,899,814 - "Active Cover Plates," Issued February 20, 2018

The Invention Explained

  • Problem Addressed: Similar to the ’180 Patent, this patent addresses adding functionality to cover plates. It further refines the design to account for the physically constrained space between an outlet body and the surrounding electrical box, and the need to prevent the power-drawing prongs from shorting against the box (’814 Patent, col. 3:5-15).
  • The Patented Solution: The invention claims a cover plate with a prong that includes an "insulating tab." This tab extends from the cover plate's back surface and is positioned to physically separate the prong's conductive parts from the wall of the electrical box, thereby preventing electrical shorts while guiding the prong into place (’814 Patent, col. 15:52-60; Fig. 2D).
  • Technical Importance: The inclusion of an integrated insulating tab enhances the safety and reliability of the power-drawing mechanism, particularly in installations where the clearance between the outlet and the electrical box is minimal (Compl. ¶11).

Key Claims at a Glance

  • The complaint asserts independent claim 1 (’814 Patent, col. 15:45-67; Compl. ¶54).
  • The essential elements of independent claim 1 are:
    • An active cover plate system with longitudinal, lateral, and transverse directions.
    • A face plate with an outlet aperture.
    • A prong extending rearward from the back surface of the face plate.
    • An insulating tab also extending rearward from the back surface of the face plate, positioned outboard of the prong, and comprising a wall extending at least partially along a length of the prong.
    • The prong resiliently deflects between a neutral position and a deflected position located outboard of the neutral position.
    • The insulating tab tracks the prong as it deflects.
  • The complaint reserves the right to assert claims that depend from claim 1 (Compl. ¶54).

U.S. Patent No. 10,109,945 - "Active Cover Plates," Issued October 23, 2018

  • Technology Synopsis: This patent refines the design of the power-drawing prongs. It describes a prong with a "resilient contact" that has a "bow shape," where movement of the middle portion of the bow causes the end of the contact to move, facilitating compression and ensuring a stable connection with the screw terminal (’945 Patent, col. 16:5-24).
  • Asserted Claims: Independent claims 1 and 8 (Compl. ¶72).
  • Accused Features: The LumiCover and GloCover products are alleged to use a prong and contact mechanism that practices the claimed invention (Compl. ¶71).

U.S. Patent No. 10,373,773 - "Active Cover Plates," Issued August 6, 2019

  • Technology Synopsis: This patent discloses a prong structure comprising a "conductive upright" and an "electrically insulative material positioned inboard of" it. This layered construction provides structural support while ensuring the conductive path is insulated from the front-facing parts of the device and guided away from potential shorts (’773 Patent, col. 16:5-14).
  • Asserted Claims: Independent claims 1, 11, and 17 (Compl. ¶90).
  • Accused Features: The LumiCover and GloCover products are alleged to incorporate the claimed composite prong structure (Compl. ¶89).

U.S. Patent No. 10,381,788 - "Active Cover Plates," Issued August 13, 2019

  • Technology Synopsis: This patent focuses on a specific prong design that includes a "cantilever spring." The spring is configured to provide a restoring force to a resilient contact, assisting it in making and maintaining a secure electrical connection with the screw terminal after being compressed during installation (’788 Patent, col. 8:56-62).
  • Asserted Claims: Independent claims 1 and 12 (Compl. ¶108).
  • Accused Features: The LumiCover and GloCover products are alleged to use prongs with a spring mechanism that infringes the patent (Compl. ¶107).

U.S. Patent No. 10,381,789 - "Active Cover Plates," Issued August 13, 2019

  • Technology Synopsis: This patent is similar to the ’788 Patent but further specifies the cantilever spring as "extending from an upper portion of an upright." This claim appears directed to the specific geometry and point of action of the spring mechanism within the prong assembly (’789 Patent, col. 8:16-24).
  • Asserted Claims: Independent claims 1, 9, and 20 (Compl. ¶126).
  • Accused Features: The LumiCover and GloCover products are alleged to use a prong and cantilever spring design that meets the specific limitations of this patent (Compl. ¶125).

U.S. Patent No. 10,404,045 - "Active Cover Plates," Issued September 3, 2019

  • Technology Synopsis: This patent claims an active cover plate with a "resiliently deflectable prong" and a "separate insulating tab." The separation of the conductive prong from the insulating tab is a key claimed feature, allowing the two components to be distinct parts of the assembly (’045 Patent, col. 8:1-9).
  • Asserted Claims: Independent claims 1, 10, and 15 (Compl. ¶144).
  • Accused Features: The LumiCover and GloCover products are alleged to have a prong assembly with a separate insulating component that infringes the patent (Compl. ¶143).

III. The Accused Instrumentality

  • Product Identification: The accused products are powered cover plates sold under the exemplary brand names "LumiCover" and "GloCover" (Compl. ¶25).
  • Functionality and Market Context: The complaint alleges these are powered cover plates that install over standard electrical outlets to provide functions such as LED nightlights, power failure lights, USB charging ports, and motion-activated lighting (Compl. ¶¶ 25, Page 9). The products are marketed as being easy to install without wiring (Compl. ¶¶ Page 9, 11). A marketing image from a Westek Lighting Catalog depicts a "LUMICOVER" product with the text "INSTALLS IN SECONDS! NO WIRING NEEDED!" (Compl. ¶ Page 11). Packaging for the "Lumicover Nightlight Wallplate" shows that it is designed to "Press" onto an outlet to draw power (Compl. ¶ Page 9). The complaint alleges Defendant sells these products through major retail and ecommerce channels, including The Home Depot, Lowes, Walmart, and Amazon.com (Compl. ¶¶ 29, 31).

IV. Analysis of Infringement Allegations

The complaint references claim charts attached as exhibits that were not included with the filed document (Compl. ¶¶ 36, 54). Accordingly, a narrative summary of the infringement theory is provided below.

  • ’180 Patent Infringement Allegations
    The complaint alleges that the Accused Products, such as the LumiCover and GloCover, are "active cover plates" that practice all elements of at least independent claim 11 of the ’180 Patent (Compl. ¶¶ 36-37). The core of the infringement theory is that the Accused Products include prongs that extend from the back of the cover plate and are configured to physically contact the side screw terminals of a standard electrical receptacle. This contact allegedly allows the products' internal electrical load—such as an LED nightlight—to draw power from the receptacle, thereby infringing the claim (Compl. ¶¶ 25, 35).

  • ’814 Patent Infringement Allegations
    The complaint alleges that the Accused Products also practice all elements of at least independent claim 1 of the ’814 Patent (Compl. ¶¶ 54-55). The infringement theory for this patent centers on the allegation that the Accused Products include not only a power-drawing prong but also an "insulating tab." This tab is alleged to be positioned alongside the prong to prevent it from making electrical contact with the side of the metal electrical box in which the outlet is housed, thereby practicing the safety feature claimed in the patent (Compl. ¶¶ 11, 53).

  • Identified Points of Contention:

    • Scope Questions: A central issue may be how the term "prongs" in the ’180 Patent is construed, and whether the specific structure of the contacts on the LumiCover and GloCover products falls within that scope. For the ’814 Patent, a key question will be whether the accused devices include a distinct structure that meets the definition of an "insulating tab" that "tracks" the prong as it deflects, or if their design is technically distinguishable.
    • Technical Questions: While the general function appears similar, a factual question will be whether the Defendant’s products achieve this function using the specific structures and methods recited in the claims. The complaint’s reference to the ITC GEO and CBP Ruling Letter, which found infringement, suggests Plaintiff possesses evidence on this point, but the court will have to make its own independent determination based on the evidence presented in this case (Compl. ¶¶ 22-23).

V. Key Claim Terms for Construction

  • Term 1 (from ’180 Patent, Claim 11): "prongs configured to extend between the body of the electrical receptacle and sides of an electrical receptacle box and contact the screw terminals"

    • Context and Importance: This term defines the core power-drawing mechanism. The dispute will likely focus on the required structure, shape, and resilience of the "prongs" and the nature of the "contact" with the terminals. Practitioners may focus on this term because the precise physical implementation of this connection is central to the infringement analysis.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The specification describes the prongs in general terms as "electrically conductive protrusions" (’180 Patent, col. 2:5-6) and shows various embodiment shapes, which may support an interpretation that covers any protrusion achieving the stated function.
      • Evidence for a Narrower Interpretation: The figures show specific embodiments with distinct shapes, such as curved or angled prongs (e.g., ’180 Patent, Figs. 4, 6A-6C). Defendant may argue that the term should be limited to structures similar to those disclosed, rather than any conceivable structure that can make contact.

  • Term 2 (from ’814 Patent, Claim 1): "insulating tab ... positioned outboard of the prong ... tracking the prong as the prong deflects"

    • Context and Importance: This term is a key addition in the ’814 Patent, introducing a specific safety feature. The case may turn on whether the accused products have a structure that qualifies as a distinct "insulating tab" and whether that structure "tracks" (i.e., moves with) the prong in the claimed manner.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The specification describes the function of the tab as preventing the prong from touching the electrical box (’814 Patent, Abstract), which could support construing the term to cover any structure that performs this insulating and guiding function in concert with the prong.
      • Evidence for a Narrower Interpretation: The patent figures depict the "insulating tab" as a distinct, wall-like structure extending from the back of the faceplate (e.g., ’814 Patent, Fig. 2D, element 34). Defendant may argue that this structure is distinct from any insulating features on its own products, and that "tracking" implies a specific type of coordinated movement not present in the accused devices.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges induced infringement, stating that Defendant instructs its customers (including retailers like The Home Depot) and end-users on how to install and use the Accused Products in an infringing manner through marketing materials, packaging, and user guidelines (Compl. ¶¶ 45, 47, 63, 65). It also alleges contributory infringement on the basis that the Accused Products have no substantial non-infringing use and constitute a material part of the invention (Compl. ¶¶ 44, 62).
  • Willful Infringement: Willfulness is alleged based on Defendant’s purported knowledge of the patents and infringement since at least October 2020, when Plaintiff sent a notice letter that Defendant allegedly ignored (Compl. ¶¶ 38, 56). The complaint further alleges that Defendant’s continued importation and sale of the Accused Products after the issuance of the ITC’s GEO and the adverse CBP ruling demonstrates willful, wanton, and deliberate infringement (Compl. ¶¶ 32, 48, 66).

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

  • A core issue will be the consequence of prior adjudication: To what extent will the findings of the ITC and CBP—that the Accused Products infringe and should be excluded from importation—influence the court’s analysis of liability and, particularly, willfulness? This history frames the dispute not as an initial accusation but as an alleged ongoing violation in the face of multiple adverse administrative rulings.
  • A key technical question will be one of structural and functional specificity: While the Accused Products and patented inventions operate in the same general manner, the case will likely devolve into a granular analysis of whether the precise physical structures of the Accused Products' prongs and insulating features meet the specific limitations recited in the asserted claims, a question that will be heavily dependent on claim construction.
  • Finally, a central question for damages will be deliberateness: Based on the extensive history alleged in the complaint, was the Defendant's conduct objectively reckless, justifying a finding of willful infringement and potential enhancement of damages under 35 U.S.C. § 284?
