II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,213,885 - "Modular Furniture Assembly," issued May 8, 2007
The Invention Explained
- Problem Addressed: The patent background describes challenges with conventional furniture, which is often difficult to transport, clean, and reconfigure due to its bulk and permanent assembly methods like nails or staples (’885 Patent, col. 1:5-23). Consumers desire furniture that is versatile, durable, easily moved into difficult-to-access locations, and can serve multiple functions (’885 Patent, col. 1:53-59).
- The Patented Solution: The invention is a modular furniture assembly comprising standardized "base" (seating) and "transverse" (back/arm) members that can be detachably connected using a tool-less coupler (’885 Patent, col. 2:1-7). This design allows a user to easily assemble, disassemble, and rearrange the components into numerous different furniture configurations, such as chairs or couches (’885 Patent, Fig. 1; col. 2:30-33).
- Technical Importance: This modular approach simplified manufacturing by allowing for the production of standardized components and enabled consumers to customize furniture layouts and move large pieces into spaces where traditional furniture would not fit (Compl. ¶17, 19).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶33).
- Claim 1 requires:
- A base with a frame assembly, at least one foot, and at least one aperture.
- A transverse member with a frame assembly, at least one foot, and at least one aperture.
- A coupler that detachably couples the transverse member to the base by being pushed downward when the components are positioned upright on the floor and their apertures are aligned, allowing the creation of different furniture assemblies.
- The complaint does not explicitly reserve the right to assert dependent claims.
U.S. Patent No. 7,419,220 - "Modular Furniture Assembly," issued September 2, 2008
The Invention Explained
- Problem Addressed: As a continuation of the application leading to the ’885 Patent, the ’220 Patent addresses the same general problems of conventional furniture. It specifically introduces a solution for improving the ease of cleaning and customization.
- The Patented Solution: The invention builds on the modular system of the parent patent by explicitly claiming removable "liners" (i.e., fabric covers) for both the base and transverse members (’220 Patent, Claim 1). These liners are adapted to cover the frame assemblies of the respective components, adding another layer of modularity to the system. The parent '885 patent specification notes that removable outer liners allow for easy laundering and enable consumers to interchange styles and colors (’885 Patent, col. 4:1-8).
- Technical Importance: The inclusion of removable liners provides a practical way for consumers to clean furniture and change its aesthetic appearance without replacing the entire piece.
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶44).
- Claim 1 requires:
- A base with a frame assembly, at least one foot, and at least one aperture.
- A base liner adapted to cover the frame assembly of the base.
- A transverse member with a frame assembly, at least one foot, and at least one aperture.
- A transverse member liner adapted to cover the frame assembly of the transverse member.
- A coupler with the same functional requirements as in Claim 1 of the ’885 Patent.
- The complaint does not explicitly reserve the right to assert dependent claims.
U.S. Patent No. 10,806,261 - "Modular Furniture Assembly," issued October 20, 2020
- Technology Synopsis: This patent describes a modular furniture assembly focusing on the structural relationship between the components. The invention comprises a base member, a transverse member with a height "substantially greater than the height of the base," and a coupler that selectively extends through a hole in the transverse member to connect the two pieces (’261 Patent, Abstract; Claim 1).
- Asserted Claims: The complaint asserts independent claim 1 (Compl. ¶55).
- Accused Features: The complaint alleges that the base, taller transverse members, and connecting couplers of the Accused Products meet the limitations of the asserted claim (Compl. ¶55).
U.S. Patent No. 7,963,612 - "Modular Furniture Assembly," issued June 21, 2011
- Technology Synopsis: This patent claims a modular furniture assembly defined by specific dimensional relationships between rectangular components. The key inventive concept is a spatial relationship where the length of a first transverse member ("A") is substantially equal to the sum of the length of the base member ("B") and the width of a second transverse member ("C"), enabling precise and varied configurations (’612 Patent, Claim 8).
- Asserted Claims: The complaint asserts independent claim 8 (Compl. ¶66).
- Accused Features: The complaint alleges that the rectangular base and transverse members of the Accused Products, along with their respective dimensions, infringe the claimed spatial relationships (Compl. ¶66, pp. 25-27).
U.S. Patent No. 11,253,073 - "Modular Furniture System with Storage Base," issued February 22, 2022
- Technology Synopsis: This patent adds a functional element to the modular furniture concept by incorporating storage. The invention claims a base that includes a frame assembly defining a "storage compartment," providing a convenient storage area for users, in addition to the standard seating surface and modular connection features (’073 Patent, Claim 1).
- Asserted Claims: The complaint asserts independent claim 1 (Compl. ¶77).
- Accused Features: The complaint alleges that the base sections of the Accused Products, which are advertised as serving as storage, infringe the claims (Compl. ¶77, p. 32).
III. The Accused Instrumentality
Product Identification
The accused products are the "Transformer Modular Couch" and "Transformer Outdoor Seating" lines of furniture (collectively, "Accused Products") (Compl. ¶13).
Functionality and Market Context
The Accused Products are modular furniture systems composed of interchangeable base and side components that allow for the creation of numerous configurations (Compl. ¶28). The complaint provides an image from the Transformer Couch Manual illustrating how a user assembles the product by connecting base and side pieces (Compl. ¶33, p. 12). Plaintiff alleges these products are "knock-offs" of its Sactionals line and copy its innovative elements (Compl. ¶13).

Identified Points of Contention
- Scope Questions: The infringement analysis for the ’885 and ’220 Patents may focus on the specific functional language of the "coupler" limitation. A question for the court could be whether the accused coupler's method of insertion and removal, as shown in product manuals (Compl. ¶33, p. 12), meets the claim requirement that it be "pushed downward...thereby allowing the coupler to be inserted or removed while the base and the transverse member are positioned on the floor in an upright orientation." The interpretation of "thereby allowing" could be a point of dispute.
- Technical Questions: A potential technical question is whether the receiving feature in the Accused Products' frame constitutes an "aperture formed therein" as that term is understood in the context of the patent specification. The ’885 Patent describes the aperture being formed by "grooves" in a support member (’885 Patent, col. 9:30-44), which may raise the question of whether the claim scope is limited to that specific structure.
V. Key Claim Terms for Construction
The Term: "coupler"
- Context and Importance: This term is central to the claimed invention, as it defines the mechanism for the modular system's reconfigurability. Its construction will determine whether Defendant’s connecting "shoe" falls within the scope of the claims.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claims define the "coupler" functionally, by what it does ("detachably coupling the transverse member to the base"). The specification also mentions various types of couplers, including a flared coupler and a ratcheting coupler, suggesting the term is not limited to a single embodiment (’885 Patent, col. 17:1-5).
- Evidence for a Narrower Interpretation: The specification heavily features a specific embodiment of the coupler as an "elongate, U-shaped member" that "sandwiches" portions of the base and transverse members (’885 Patent, Fig. 4; col. 12:48-60). A party might argue that the term should be limited by these detailed descriptions, particularly when combined with the specific functional limitations on how it is inserted and removed.
The Term: "aperture formed therein"
- Context and Importance: This term defines where the "coupler" is received. The nature and location of this opening are essential for infringement. Practitioners may focus on this term because the patents' detailed description links the "aperture" to a specific structure of "grooves" in a support plate.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: "Aperture" has a plain and ordinary meaning of an opening or hole. The claims do not further limit its structure, only its location ("in" the frame assembly).
- Evidence for a Narrower Interpretation: The detailed description of the ’885 Patent explains that "grooves 62a-f each form a portion of an aperture in frame assembly 16" (’885 Patent, col. 9:36-39). A defendant may argue this disclosure limits the term "aperture" to the specific grooved structure depicted and described, rather than any simple opening.
VI. Other Allegations
- Indirect Infringement: The complaint alleges induced infringement, stating that Defendants encourage infringement by promoting, advertising, and providing instructions (such as user manuals) that direct customers to assemble and use the Accused Products in an infringing manner (Compl. ¶34, 45).
- Willful Infringement: Willfulness is alleged for all asserted patents based on Defendants having actual knowledge of the patents, at least due to two pre-suit cease-and-desist letters sent by Plaintiff on September 7, 2023, and November 11, 2023 (Compl. ¶26, 36).
VII. Analyst’s Conclusion: Key Questions for the Case
- Claim Scope and Construction: A central issue will be one of claim scope and construction: How will the court define the term "coupler", particularly in light of the claim language requiring a specific "pushed downward" method of operation? The resolution will likely determine whether the functional requirements of the claims read on the mechanism used in the Accused Products.
- Technical Operation: A key evidentiary question will be one of technical operation: Does the accused connection mechanism, as depicted in instructional materials (Compl. ¶33, p. 12), function in the specific manner required by the asserted claims? The case may turn on a factual comparison of whether the accused coupler is not only inserted downward to connect but is also "thereby" able to be removed while the components remain upright on the floor.
