Case Timeline

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

U.S. Patent No. 6,471,565 - "Interactive Toy"

The Invention Explained

• Problem Addressed: The patent describes a need for toys that can intelligently interact with a range of accessories beyond simple presence detection. Prior art systems using magnets or basic resonators could not uniquely identify different accessories or exchange information with them. ( ’565 Patent, col. 1:24-39).
• The Patented Solution: The invention is a system comprising a "toy proper" (e.g., a doll or a base unit) and multiple accessories. The toy proper contains a processing unit and an "inductive coupler," while each accessory contains an "inductive label" (e.g., an RFID tag). The system's novelty lies in the coupler and label exchanging binary data through the modulation of a radio frequency signal, allowing the toy proper to not just detect but specifically identify an accessory and trigger unique functions. (’565 Patent, Abstract; col. 2:11-21). Figure 2 of the patent schematically illustrates the central processing unit (1) interacting with an inductive coupler (3) which in turn communicates with an inductive label (8) on an accessory.
• Technical Importance: This technology enables a more sophisticated form of interactive play, where a central toy can recognize a wide variety of specific objects—a particular character, tool, or vehicle—and alter its behavior or the state of a connected game accordingly.

Key Claims at a Glance

• The complaint asserts at least Claim 1. (Compl. ¶44).
• Independent Claim 1 of the ’565 Patent requires:
  • A toy comprising a toy proper and a plurality of accessories
  • The toy proper including at least one processing unit, an autonomous electrical supply, an assembly of a sensor and/or actuator, and at least one inductive coupler connected to the processing unit
  • Each accessory comprising at least one inductive label
  • The inductive coupler and inductive label interact electromagnetically via a current of defined frequency
  • The inductive coupler and label "exchange" binary data corresponding to "at least one of a phase and an amplitude state of the frequency modulation"
• The complaint does not explicitly reserve the right to assert dependent claims but references infringement of "one or more claims." (Compl. ¶¶45, 48).

III. The Accused Instrumentality

Product Identification

The accused products are the "Disney Infinity" line of games and associated hardware, including the "Infinity Base" and various "Character Figures," "Play Set Pieces," "Game Discs," and "Power Discs." The complaint focuses on the Disney Infinity 2.0 Edition Starter Pack. (Compl. ¶¶15-16).

Functionality and Market Context

The Disney Infinity system is a "toys-to-life" video game where players place physical figurines onto a peripheral device, the Infinity Base. The complaint alleges this base uses RFID technology to identify the specific figurine placed upon it and makes the corresponding character available for play within the video game. (Compl. ¶¶15, 24, 27). An image provided in the complaint shows a Character Figure being placed on an illuminated "circular spot" on the Infinity Base, which corresponds to an in-game event. (Compl. ¶36, p. 18). The complaint alleges the Infinity Base can both read data from and write data to the Character Figures, for example, to save a character's level or "ownership" data. (Compl. ¶30).

IV. Analysis of Infringement Allegations

’565 Patent Infringement Allegations

• Identified Points of Contention:
  • Technical Questions: A central question will be whether the communication protocol used by the Disney Infinity system constitutes an "exchange" of "binary data corresponding to... a phase... state of the frequency modulation" as required by the claim. The complaint’s reliance on FCC documents indicating "BPSK modulation" (Compl. ¶42) is a direct attempt to meet this limitation, but the precise nature and extent of the data "exchange" may be a point of dispute. The complaint includes a photograph of an accessory's internal RFID tag, comprising a chip and antenna, to support this element. (Compl. p. 16).
  • Scope Questions: The definition of "toy" may be contested. While the patent’s primary embodiment is a baby doll ( ’565 Patent, Fig. 1), its claims and specification also contemplate applications like children's kitchens, workbenches, and vehicle playsets ( ’565 Patent, col. 5:1-15), which may support a broader construction that covers a video game peripheral.

V. Key Claim Terms for Construction

• The Term: "exchanges... binary data"

• Context and Importance: This term is critical because it distinguishes the claimed invention from simpler prior art systems that might only detect the presence of an accessory. The infringement case hinges on proving the Infinity Base and its accessories engage in a two-way or sufficiently complex one-way transfer of modulated binary data, not just a simple response signal. Practitioners may focus on this term to dispute whether the accused product's operation, particularly the alleged BPSK modulation and read/write capability (Compl. ¶30), meets the claim's requirements.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent does not define a specific data protocol, suggesting any exchange of binary information could suffice. The purpose is to "identify the accessories" ( ’565 Patent, col. 4:57-58) and allow the toy to "react to its environment" ( ’565 Patent, col. 4:61-62).
  • Evidence for a Narrower Interpretation: The detailed description of an "identification-code exchange" ( ’565 Patent, col. 4:57) and the ability to "write" information into labels ( ’565 Patent, col. 2:27-32) could suggest a requirement for a specific, structured data dialogue beyond a simple ID broadcast.

• The Term: "toy proper"

• Context and Importance: The applicability of the patent to the accused product depends on the "Infinity Base" falling within the definition of a "toy proper." Defendants may argue that a video game peripheral is a distinct class of electronic device, not a "toy" as envisioned by the patent.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent specification explicitly extends the invention's scope beyond a single doll embodiment to include "children's kitchens," "workbenches or workshops," "garages with a fleet of vehicles," and "scenery" ( ’565 Patent, col. 5:1-15). This language suggests the term is meant to be capacious.
  • Evidence for a Narrower Interpretation: The patent's primary illustrative embodiment is a "baby doll (10)" ( ’565 Patent, col. 2:42-43). The term "toy" itself, in the context of 1999, may be argued to imply simpler, standalone play objects rather than peripherals for complex electronic games.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement of infringement, stating that Disney provides instructions on its websites that teach and encourage end-users to use the accused products in an infringing manner. (Compl. ¶47).
• Willful Infringement: The complaint alleges that Disney has had "actual or constructive knowledge of the '565 Patent since at least the date of service of this Complaint," forming a basis for post-suit willful infringement. (Compl. ¶46).

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

• A central issue will be one of technical proof: Does the communication between the Infinity Base and its accessories meet the claim requirement of an "exchange" of "binary data corresponding to at least one of a phase... state of the frequency modulation"? The case will likely depend on expert testimony and discovery interpreting the system's actual operation, particularly the BPSK protocol alleged in the complaint's supporting FCC documents.
• A second core issue will be one of definitional scope: Can the term "toy," described in a 1999-priority patent with a doll as its main example, be construed to encompass a sophisticated video game peripheral? The outcome may turn on whether the patent's broader examples of interactive playsets are sufficient to cover the "toys-to-life" game category.
