II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,918,964 - "Three-Dimensional Geometric Art Toy"
- Issued: February 16, 2021
The Invention Explained
- Problem Addressed: The patent background describes the challenge of creating reconfigurable toys from basic geometric shapes, like tetrahedrons, that can be stably maintained in various complex polygonal configurations for educational, puzzle, or artistic display purposes (U.S. Patent No. 10,918,964, col. 1:12-24).
- The Patented Solution: The invention is a "geometric art toy" comprising two sets of tetrahedral "toy members" that are movably coupled to one another (e.g., hinged) (’964 Patent, col. 1:36-40). Each member in the first set contains magnets oriented to exhibit a "first polarity," while each member in the second set contains magnets with a "substantially opposite" second polarity, allowing the toy to be selectively and stably positioned in multiple different configurations, such as a cube or star (’964 Patent, Abstract; col. 3:23-35).
- Technical Importance: This approach allows for a single, interconnected device to transform into numerous distinct geometric shapes that hold their form magnetically, creating a dynamic puzzle and art object from a fixed number of components (’964 Patent, col. 3:23-44).
Key Claims at a Glance
- The complaint asserts independent claim 7 (Compl. ¶169).
- Essential Elements of Claim 7:- A geometric art toy comprising:
- six first toy members formed as tetrahedrons, each with less than three first magnets;
- six second toy members formed as tetrahedrons, each with less than three second magnets;
- wherein the second magnets have a polarity that is not specified relative to the first magnets;
- wherein each first toy member is directly and movably coupled to another first toy member and to one of the second toy members;
- such that each first toy member is configured to magnetically couple with the second toy member to which it is directly and movably coupled, but not with the other first toy member to which it is directly and movably coupled.
 
- The complaint notes that Plaintiff may assert additional claims (Compl. ¶173).
U.S. Patent No. 11,660,547 - "Three-Dimensional Geometric Art Toy"
- Issued: May 30, 2023
The Invention Explained
- Problem Addressed: The '547 patent, which shares a specification with the '964 patent, addresses the same technical problem of creating a stable, multi-configuration geometric toy from tetrahedral components (U.S. Patent No. 11,660,547, col. 1:12-24).
- The Patented Solution: The solution is again a geometric toy made of first and second sets of tetrahedral members with distinct magnetic properties that allow them to be reconfigured. The claims of the ’547 Patent are directed to a "puzzle" comprising twelve tetrahedral bodies coupled by hinges, where magnets within the bodies are configured to magnetically couple with only one of the two bodies to which it is directly hinged (’547 Patent, col. 14:12-32).
- Technical Importance: This patent further protects the concept of using selective magnetic coupling within a hinged, closed-loop structure of geometric shapes to enable complex transformations (’547 Patent, col. 3:23-35).
Key Claims at a Glance
- The complaint asserts independent claim 12 (Compl. ¶180).
- Essential Elements of Claim 12:- A puzzle comprising:
- twelve tetrahedral bodies coupled together by hinges;
- each body comprises six edges and is coupled along two edges to two different bodies;
- each body comprises at least one and up to three magnets, which are the only magnets of that body;
- each magnet has a polarity and position configured to magnetically couple with at least one magnet of at least one other body;
- wherein in a first configuration, each body magnetically couples with only one of the two bodies to which it is coupled along its edges.
 
- The complaint notes that Plaintiff may assert additional claims (Compl. ¶184).

Identified Points of Contention
- Scope Questions: A central question may be whether the accused product's use of "twelve rare earth magnets and twelve metal magnets" (Compl. ¶156) meets the claim limitation requiring "second magnets" with a specific "polarity" (’964 Patent, col. 14:15-18) or simply "magnets" (’547 Patent, col. 14:18). The analysis may turn on whether a piece of metal, which is magnetically attractable but may not be a permanent magnet with its own polarity, can be construed as a "magnet" as claimed.
- Technical Questions: The complaint alleges the tetrahedral modules are "hingedly coupled to each other by adhesive stickers" (Compl. ¶155). A point of contention may be whether a flexible "adhesive sticker" constitutes the "movably coupled" or "hinge" structure required by the claims and described in the patent specifications.
V. Key Claim Terms for Construction
- The Term: "magnets" (as used in reference to both the "first magnets" and "second magnets" in the '964 and '547 patents)
- Context and Importance: The construction of this term is critical because the complaint alleges the accused product contains both "rare earth magnets" and "metal magnets" (Compl. ¶156). The case may depend on whether a piece of metal, which is magnetically receptive but not necessarily a polarized magnet itself, falls within the scope of the term "magnet" as used in the claims. Practitioners may focus on this term because if "magnet" is construed to require an element with its own permanent magnetic field and distinct polarity, the infringement allegation against the "metal magnet" components could be challenged.
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: The specification's focus is on the interaction that allows the toy to be "stably maintained" in different configurations (’964 Patent, col. 1:47-50). An argument could be made that any component creating the necessary magnetic attraction to achieve this stability, including a magnet-and-metal pairing, falls within the intended scope.
- Evidence for a Narrower Interpretation: The patent repeatedly and distinctly refers to "first magnets" and "second magnets," each "oriented to exhibit a... polarity" that is "substantially opposite" to the other set (’964 Patent, Abstract; col. 1:36-40). This language suggests the inventor contemplated two sets of actual magnets with opposing polarities, not one set of magnets and one set of magnetically attractable material.
 
VI. Other Allegations
- Indirect Infringement: The complaint alleges both induced and contributory infringement for all four patents-in-suit. The allegations state that with knowledge from the October 23, 2023 notice letter, Defendants induced suppliers and customers to infringe and contributed to infringement by selling the accused products, which are alleged to be a material part of the patented inventions (Compl. ¶¶ 173-174, 184-185, 195-196, 206-207).
- Willful Infringement: Willfulness is alleged for all four patents based on Defendants' continued manufacturing and selling of the accused products after receiving actual notice of the patents and infringement allegations in the cease and desist letters dated October 23, 2023, and November 16, 2023 (Compl. ¶¶ 171, 182, 193, 204).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "magnet," particularly as used in the context of requiring a "second polarity," be construed to cover the "metal magnets" (i.e., magnetically receptive metal pieces) allegedly used in the accused "Magic Cube"? The resolution of this claim construction issue may be determinative for infringement of the '964 and '547 patents.
- A second key question will be one of structural equivalence: do the "adhesive stickers" that allegedly connect the modules of the accused "Magic Cube" meet the claim requirement of being "movably coupled" or functioning as "hinges" as contemplated by the patent?
- A central evidentiary question for damages will be one of willfulness: what evidence will demonstrate that Defendants' decision to continue selling the accused products after receiving detailed notice letters was objectively reckless, thereby justifying enhanced damages?
