II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 11,006,761 - “Mattress Foundation”
The Invention Explained
- Problem Addressed: The patent's background section notes that conventional mattress foundations are often "large and bulky, making them difficult to store and/or move," particularly for shipping to a consumer's home and navigating within it (’761 Patent, col. 2:39-44). Prior collapsible designs are described as having their own deficiencies, such as being difficult to assemble or not collapsing into a sufficiently small size (’761 Patent, col. 2:45-50).
- The Patented Solution: The invention is a mattress foundation that can be disassembled into component parts for compact shipping and then reassembled without tools (’761 Patent, col. 15:18-65). It consists of head and foot panels, side panels, and a central longitudinal support assembly. A series of crossbars are placed into corresponding notches on the side panels and the central support assembly to create a flat, stable surface for a mattress. The design of the longitudinal support, which features separate left-side and right-side notches divided by a barrier, is a key structural element illustrated in Figure 33 (’761 Patent, col. 16:36-48; Fig. 33).
- Technical Importance: The invention provides a method for constructing a robust, full-size bed foundation from components small enough to fit in a standard shipping box, addressing a key logistical challenge for online mattress and furniture retailers (’761 Patent, col. 2:41-44).
Key Claims at a Glance
- The complaint asserts dependent claims 2, 7-9, 11, 12, and 14, all of which depend from independent claim 1.
- The essential elements of Independent Claim 1 are:
- A head end panel assembly and a foot end panel assembly.
- Left and right side panel assemblies attached to and extending between the head and foot end panel assemblies, each having a plurality of notches.
- A longitudinal support assembly disposed between the side panels, attached to the head and foot end panels, and also having a plurality of notches.
- A first set of crossbars disposed between the left side panel and the longitudinal support assembly, with ends fitting into their respective notches.
- A second set of crossbars disposed between the right side panel and the longitudinal support assembly, with ends fitting into their respective notches.
- A requirement that the longitudinal support assembly has a top surface with both left-side and right-side notches formed into it.
- A requirement that the left-side notches are separated from the right-side notches by a barrier.
III. The Accused Instrumentality
Product Identification
The "GhostBed All-in-One Foundation" and the "All-in-One Foundation by Nature's Sleep," which the complaint alleges are structurally identical products (Compl. ¶1, ¶31).
Functionality and Market Context
The accused product is a metal mattress foundation sold disassembled in a box for consumer assembly (Compl. ¶32). The complaint alleges the product is composed of head and foot end panels, side panels, a central longitudinal support, and crossbars that are inserted into notches on the panels and central support to form the frame (Compl. ¶¶34-40). The complaint includes a screenshot from an assembly video for the accused product, with labels added by the Plaintiff to identify the components. This screenshot shows an assembled foundation with a clear head end panel, foot end panel, side panels, and a central longitudinal support with crossbars spanning the gaps (Compl. ¶32). The products are allegedly sold through various major online retail channels, including the defendant’s own websites, Amazon.com, HomeDepot.com, and Macys.com (Compl. ¶¶23-29).

Identified Points of Contention
- Technical Questions: The complaint presents a highly detailed, element-by-element mapping of the accused product onto the claim limitations, supported by annotated photographs and screenshots. The central technical question for the court will be whether the defendant can establish any legally significant technical or functional distinction between its product's components and those recited in the claims. For example, what evidence, if any, will be presented to argue that the accused product's central beam is not a "longitudinal support assembly" or that the divider between its notches is not a "barrier" within the meaning of the patent?
- Scope Questions: The patent claims are not limited to a specific material, but various embodiments describe wood or metal construction (’761 Patent, col. 4:50-51, col. 16:1-2). The complaint alleges the accused product is made primarily of steel (Compl. ¶46). While this appears to fall within the patent's scope, it raises the question of whether any arguments related to material-specific properties or prosecution history disclaimers might be raised by the defense.
V. Key Claim Terms for Construction
The Term: "longitudinal support assembly"
Context and Importance: This term defines the central spine of the patented foundation. Its construction is critical because its structure and features, including the "notches" and "barrier," are central to the infringement theory. Dependent claim 11 further defines this assembly as having a "frame structure, including an upper beam and a lower beam." The complaint alleges the accused product has this specific structure (Compl. ¶48, ¶54). Practitioners may focus on this term to determine if limitations from dependent claims or the specification should be read into the independent claim.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: Claim 1 itself only requires the assembly to be disposed between the side panels, attached to the end panels, and have notches along its length (’761 Patent, cl. 1(e)).
- Evidence for a Narrower Interpretation: The specification and dependent claim 11 describe a more specific "frame structure, including an upper beam and a lower beam, separated from each other by a gap of at least 4 inches, with supports between the upper beam and the lower beam" (’761 Patent, cl. 11; col. 16:49-55). A defendant may argue that this more detailed structure is the "invention" and should limit the scope of the broader term in Claim 1.
The Term: "barrier"
Context and Importance: This term defines the specific feature that separates the left-side and right-side notches on the longitudinal support assembly. The complaint explicitly identifies this feature on the accused product with photographic evidence (Compl. ¶53). Its definition is important for confirming a literal match.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim requires only that the left-side notches are "separated from the right-side notches by a barrier," suggesting any structure that performs this separating function would suffice (’761 Patent, cl. 1).
- Evidence for a Narrower Interpretation: While the claim language is broad, a party could argue that the term should be limited to the physical implementation shown in the patent's figures, such as Figure 33, which depicts a solid, raised portion of the upper surface of the support assembly.
VI. Other Allegations
Indirect Infringement
The complaint alleges inducement of infringement, asserting that the defendant instructs and encourages its customers to assemble the accused products in an infringing manner, specifically referencing a "How to Assemble Your All-in-One Foundation" video (Compl. ¶20, ¶32).
Willful Infringement
The willfulness claim is based on the allegation that the defendant has known of the ’761 patent "since at least July 15, 2021" but has continued its allegedly infringing conduct "without any reasonable basis for believing that it had a right" to do so (Compl. ¶55, ¶58).
VII. Analyst’s Conclusion: Key Questions for the Case
- A central issue will be one of evidentiary rebuttal: given the complaint's detailed photographic evidence suggesting a one-to-one correspondence between the accused product and the patent's claims, can the defendant produce contrary evidence demonstrating a meaningful structural or functional difference that creates a genuine dispute over infringement?
- The case may also turn on a question of claim scope: will the term "longitudinal support assembly" in independent Claim 1 be given its plain and ordinary meaning, or will it be narrowed by the court to incorporate the more specific "upper and lower beam" frame structure described in dependent Claim 11 and the preferred embodiments? The answer will determine the scope of protection afforded by the patent's core claim.
