II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,254,043 - “Lighted Cup Holder for Seating Arrangements,” issued February 9, 2016
The Invention Explained
- Problem Addressed: The patent’s background section describes the difficulty of locating cup holders in seating arrangements used in dark or low-visibility conditions, such as in home theaters or vehicles, which can lead to spills and damage. (’043 Patent, col. 1:52-61).
- The Patented Solution: The invention solves this problem by providing a cup holder with an integrated light source for illumination. More specifically, the invention consolidates controls for other functions of the seating arrangement—such as massage or recline mechanisms—into a flange on the cup holder, simplifying the furniture’s construction and improving user access to controls in the dark. (’043 Patent, Abstract; col. 7:6-15; Fig. 7).
- Technical Importance: This design approach centralized user controls in an accessible, illuminated location, which was a valuable feature for increasingly complex home theater and recreational vehicle seating. (’043 Patent, col. 7:6-9).

Identified Points of Contention
- Scope Questions: For the ’043, ’882, and ’221 Patents, a central dispute may arise over the scope of the phrase "a component of the seating arrangement other than the cup holder apparatus." The complaint alleges that a light strip at the base of the seat is such a component. (Compl. ¶22). This raises the question of whether lighting for the chair is distinct from the "cup holder apparatus," especially when the invention is a "lighted cup holder."
- Technical Questions: Infringement of the ’505 Patent hinges on whether the accused cup holder switch controls either a "powered reclining mechanism" or a "massaging mechanism." (Compl. ¶33). The case will depend on factual evidence demonstrating this specific link and control in the accused LCI product lines. The complaint's allegations for multiple product families are identical, which raises an evidentiary question as to whether each product implements the controls in the same infringing manner.
V. Key Claim Terms for Construction
The Term: "a component of the seating arrangement other than the cup holder apparatus" (from claim 1 of the ’043, ’882, and ’221 Patents)
- Context and Importance: The definition of this term is critical for determining the breadth of the asserted claims. A narrow construction of "cup holder apparatus" (e.g., only the physical structure for holding a cup) would mean controlling almost any other chair feature infringes. Practitioners may focus on this term because the plaintiff's infringement theory relies on the cup holder controlling an external lighting strip, and the defendant may argue that such lighting is part of the overall illumination system of the "lighted cup holder apparatus" itself.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation (of the controlled "component"): The specification provides examples of such components, including a "massage mechanism" and a "USB port," which are clearly distinct from the physical cup holder. (’043 Patent, col. 6:55-65). This supports a reading where the controlled component can be any functionally separate part of the chair.
- Evidence for a Narrower Interpretation (of the controlled "component"): A defendant could argue that the patent’s primary purpose is to illuminate the cup holder itself to prevent spills. (’043 Patent, col. 2:8-17). This context may support an interpretation where the "component other than the cup holder apparatus" must be functionally unrelated to illumination, potentially excluding the accused base lighting strip.
The Term: "operatively linked" (from claim 1 of all asserted patents)
- Context and Importance: This term is crucial for establishing the connection between the cup holder's switch and the controlled component. The nature of this "link"—whether a direct wire, a bus communication, or a software command—will be a key factual question. The complaint alleges the link exists but does not specify its technical implementation. (Compl. ¶22).
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification is not particularly limiting, describing a "cup holder controller" and showing schematic "electrical interconnection," suggesting that any form of functional control connection would satisfy the limitation. (’043 Patent, Fig. 2; col. 4:38-42).
- Evidence for a Narrower Interpretation: The figures primarily illustrate direct electrical connections and controllers. (’043 Patent, Figs. 2, 5). A party could argue that "operatively linked" should be construed in light of these disclosed embodiments and might not cover, for example, a more attenuated or indirect network-based control system if used in the accused products.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that LCI contributes to and induces infringement by selling the eMOMO HX43 Cup Holder Products to downstream recreational vehicle manufacturers (e.g., Grand Design RV, Forest River) with the knowledge and intent that those manufacturers will incorporate them into infringing seating arrangements. (Compl. ¶29, ¶38). The complaint further alleges that the cup holders are not a "staple article or commodity of commerce suitable for substantial non-infringing use." (Compl. ¶29).
- Willful Infringement: The willfulness allegations are based on purported pre-suit knowledge. The complaint claims that LCI’s supplier, eMOMO, was aware of Raffel's patents and that "eMOMO met with and instructed LCI at least as early as April, 2016, that Raffel's patents covered the eMOMO HX43 Cup Holder Products." (Compl. ¶¶16-17). These allegations of specific, direct notice form the basis of the claim for willful infringement.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the claim term "component of the seating arrangement other than the cup holder apparatus" be construed to cover an ambient light strip at the base of the chair, or is that lighting functionally part of the "lighted cup holder apparatus" itself and therefore outside the claim's scope?
- A second central issue will be one of knowledge and intent: can the plaintiff produce sufficient evidence to prove its allegation that LCI was "instructed" by its supplier about the patents-in-suit? The outcome of this factual question will be critical to the claim for willful infringement and potential enhanced damages.
- A key evidentiary question will be one of functional operation: does the accused eMOMO HX43 cup holder, as implemented across LCI's various furniture collections, actually perform the specific control functions required by each asserted claim (e.g., controlling a "powered reclining mechanism" or "massaging mechanism" for the ’505 Patent), or is there a mismatch between the broad allegations and the specific operation of each product?
