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

U.S. Patent No. 10,596,475 - "Plush Stuffed with Molded or Sculpted Foam"

The Invention Explained

• Problem Addressed: The patent’s background section notes that traditional plush toys, filled with materials like polyester fiberfill, cannot be easily compressed for shipping or concealed for a "surprise" reveal without being permanently damaged or deformed ’475 Patent, col. 1:36-46
• The Patented Solution: The invention uses a compressible foam inner (e.g., memory foam) that is larger than its flexible outer fabric covering ’475 Patent, col. 3:2-5 This size mismatch means the foam is always in a state of partial compression, even in the toy's resting state ’475 Patent, claim 1 This construction allows the toy to be further compressed for packaging and then reliably expand back to its intended shape upon release ’475 Patent, col. 2:15-19
• Technical Importance: This technology enabled cost savings in shipping and storage and facilitated the popular "blind box" or surprise-reveal style of toy packaging ’475 Patent, col. 2:24-30

Key Claims at a Glance

• The complaint asserts exemplary Claim 2, which depends on Claim 1 Compl. ¶34
• Independent Claim 1: The key elements include:
  • A "foam inner" made of "compressible foam material" with a "natural size when unconstrained."
  • A "flexible outer covering" with an "unconstrained size smaller than the natural size of the foam inner."
  • The resulting plush toy has a "first uncompressed form" where the foam is "at least partially compressed and constrained by the outer covering."
  • The toy also has a "plurality of compressed forms" smaller than the uncompressed form.
  • When released from a compressed form, the toy "expands back" to the "uncompressed form."
• Dependent Claim 2: Adds the limitation that the "foam inner is compressible to at least 33% of the natural size."
• The complaint reserves the right to assert additional claims Compl. ¶34

U.S. Patent No. 10,427,061 - "Plush Stuffed with Molded or Sculpted Foam"

The Invention Explained

• Problem Addressed: As with the '475 Patent, the invention seeks to overcome the inability of traditional plush toys to be compressed without damage ’061 Patent, col. 1:26-34
• The Patented Solution: The '061 Patent describes the same core technology of a compressible foam inner constrained by a smaller outer fabric ’061 Patent, abstract A distinguishing feature emphasized in its independent claim is that the foam inner is formed into a "character shape having at least one appendage" ’061 Patent, claim 1 The patent specification discusses how different appendages could be designed with foam that has different expansion rates to control how the character "comes to life" upon release ’061 Patent, col. 4:39-53
• Technical Importance: The technology provides a method for creating compressible, character-based toys, enhancing their appeal and creating opportunities for novel play patterns based on the expansion process ’061 Patent, col. 2:11-21

Key Claims at a Glance

• The complaint asserts exemplary Claim 1 Compl. ¶50
• Independent Claim 1: The key elements include:
  • A "foam inner formed into a character shape having at least one appendage" made of "compressible foam material."
  • A "flexible outer covering" with an "unconstrained size smaller than the natural size of the foam inner."
  • The resulting plush toy has a "first uncompressed form" where the "inner foam is constrained by the outer covering and does not achieve its natural size."
  • The toy also has a "second, compressed form smaller than the unconstrained form."
  • When released from the compressed form, the toy "expands to the uncompressed form."
• The complaint reserves the right to assert additional claims Compl. ¶50

U.S. Patent No. 11,311,814 - "Plush Stuffed with Molded or Sculpted Foam"

• Patent Identification: U.S. Patent No. 11,311,814, "Plush Stuffed with Molded or Sculpted Foam," issued on April 26, 2022 Compl. ¶20
• Technology Synopsis: This patent describes a plush toy comprising a compressible viscoelastic foam inner and a "shape defining textile fabric outer covering" that entirely surrounds it Compl. ¶65 The core inventive concept is that the outer covering compresses and constrains the foam inner, preventing it from achieving a "natural, uncompressed size or shape" Compl. ¶65
• Asserted Claims: The complaint asserts exemplary Claim 1 Compl. ¶64
• Accused Features: The complaint alleges that the accused products infringe by having a "compressible viscoelastic ('slow-rise' or 'memory') foam material" that is "compressed and constrained by the textile fabric outer covering" such that it does not achieve its natural size Compl. ¶67 Compl. ¶69

III. The Accused Instrumentality

Product Identification

• The accused instrumentalities are the "Pusheen Round Plush Squishy Assortment," "Gudetama Squishies," and "Line Friends / BT21" products, referred to collectively as the "Spin Master Products" Compl. ¶25 Compl. ¶1

Functionality and Market Context

• The complaint describes the accused products as plush toys constructed with a "slow-rise, viscoelastic polyurethane foam inner formed into a character shape" which is then enclosed by a "textile fabric outer covering" Compl. ¶¶1-2 The core functionality alleged to be infringing is this specific combination, where the foam inner is pre-compressed by the outer covering and can be further squeezed by a user, after which it slowly expands back to its resting shape Compl. ¶¶43-44 Compl. ¶¶58-59
• The complaint situates these products within the popular "squishy" trend in the toy industry, suggesting significant commercial activity Compl. ¶14
• No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Question: A potential point of contention for the '061 Patent is the scope of the term "appendage". The complaint suggests features like an "ear" or "tail" meet this limitation Compl. ¶54, which raises the question of whether the patent's language and prosecution history support construing the term to include minor character features or if it requires more distinct, limb-like structures.
• Technical Question: A factual dispute may arise over whether the accused products actually meet the "smaller than" limitation. This would require determining the "natural size" of the foam inner when fully unconstrained and comparing it to the dimensions of the outer covering, which could be a complex evidentiary issue involving destructive testing of the products.

V. Key Claim Terms for Construction

• The Term: "unconstrained size smaller than the natural size of the foam inner" ’475 Patent, claim 1 ’061 Patent, claim 1

• Context and Importance: This phrase is the linchpin of the asserted claims, as it defines the structural relationship that creates the pre-compressed state of the toy. The infringement analysis for all asserted patents will depend heavily on whether the accused products embody this specific size differential.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The claim language does not quantify the term "smaller," which could support an argument that any measurable difference in size is sufficient to meet the limitation.
  • Evidence for a Narrower Interpretation: The claims provide functional context, stating this size difference results in the foam being "constrained" and unable to "achieve its natural size" ’061 Patent, claim 1 This suggests "smaller" must be interpreted as a size difference sufficient to cause this constraining function, not a de minimis or trivial difference.

• The Term: "appendage" ’061 Patent, claim 1

• Context and Importance: This term is a key limitation of the asserted claim of the '061 Patent. Infringement requires the accused toys to possess a "character shape having at least one appendage." Practitioners may focus on this term because it distinguishes the '061 Patent from its relatives and may not be met by all "squishy" toys.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification refers to "appendages 22 or other sections" (’061 Patent, col. 4:23-24), which may suggest the term is not limited to traditional limbs. The complaint’s examples of an "ear, arm, leg, or tail" could be argued as consistent with this reading Compl. ¶54
  • Evidence for a Narrower Interpretation: The patent figures primarily depict a teddy bear with distinct arms and legs as examples of appendages ’061 Patent, Fig. 1 This could support an argument that the term should be limited to more substantial, limb-like projections rather than integrated features like ears on a simple round shape.

VI. Other Allegations

• Indirect Infringement: The complaint focuses on direct infringement under 35 U.S.C. § 271(a) Compl. ¶34 Compl. ¶50 Compl. ¶64 and does not contain specific allegations of indirect infringement.
• Willful Infringement: The complaint alleges willful infringement based on both pre-suit and post-suit knowledge. Pre-suit knowledge is alleged from a December 22, 2025 notice letter that identified the patents and accused products Compl. ¶26, which Defendant's counsel acknowledged receiving and evaluating Compl. ¶27 Post-suit knowledge is alleged from the filing of the original complaint on March 20, 2026 Compl. ¶31, with Defendants' continued sales thereafter characterized as willful and deliberate Compl. ¶32 Compl. ¶47 Compl. ¶61 Compl. ¶71

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

• A central issue will be one of claim construction and measurement: how will the court construe the phrase "unconstrained size smaller than the natural size of the foam inner," and what evidence will be sufficient to prove that the accused products meet this dimensional limitation? The case may depend on detailed factual evidence from product testing.
• A key patent-specific question will be the definitional scope of "appendage" in the '061 Patent. The court's interpretation will determine whether the accused products, some of which may have simple character shapes, fall within the scope of that patent's claims.
• A third core issue will be willfulness. Given the complaint's allegations of pre-suit notice and subsequent discussions Compl. ¶¶26-28, the question of whether any infringement was "willful and deliberate" will likely be a significant part of the case, potentially exposing the defendant to enhanced damages.
