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

U.S. Patent No. 10,021,380 - "Faster State Transitioning for Continuous Adjustable 3Deeps Filter Spectacles Using Multi-Layered Variable Tint Materials," issued July 10, 2018.

The Invention Explained

  • Problem Addressed: The patent describes that prior art methods for creating a 3D illusion from 2D video, such as those relying on the "Pulfrich effect," were sub-optimal because they did not adequately account for the speed of on-screen motion or the physical transition time of materials used in variable-tint viewing glasses (’380 Patent, col. 2:48-52, col. 3:24-33).
  • The Patented Solution: The invention proposes an electronically controlled spectacle system with lenses made of materials whose tint (optical density) can be rapidly and independently adjusted. A control unit receives signals and adjusts each lens to optimize the 3D illusion, synchronizing the tint changes with the lateral motion and luminance detected in the video source (’380 Patent, Abstract; col. 3:10-23). This precise control over the light reaching each eye is intended to create a more compelling depth effect.
  • Technical Importance: This technology sought to provide a more convincing 3D viewing experience for the vast library of existing 2D video content without the need for specialized 3D cameras or projection systems (’380 Patent, col. 2:19-25).

Key Claims at a Glance

  • The complaint asserts infringement of claims 1-30, which include independent method claims 1, 11, 21 and independent apparatus claims 6, 16, 26 (Compl. ¶8).
  • Independent Claim 1 recites a method with the following essential elements:
    • Acquiring a source video with a sequence of chronologically ordered image frames.
    • Identifying a first and second image frame from the sequence.
    • "Expanding" the first image frame to generate a first modified image frame.
    • "Expanding" the second image frame to generate a second modified image frame.
    • Generating a "bridge frame" with specific dimensional properties.
    • Displaying the modified combined image frame.
  • The complaint reserves the right to assert additional claims, including dependent claims (Compl. ¶8).

U.S. Patent No. 9,948,922 - "Faster State Transitioning for Continuous Adjustable 3Deeps Filter Spectacles Using Multi-Layered Variable Tint Materials," issued April 17, 2018.

The Invention Explained

  • Problem Addressed: The patent identifies a need to improve upon existing 2D-to-3D conversion techniques, which either required specific viewing hardware or produced a limited or flawed 3D effect (’922 Patent, col. 2:39-53).
  • The Patented Solution: The patented apparatus includes a storage medium and a processor configured to manipulate a 2D video stream. The processor obtains frames, generates new "modified" frames by altering the source frames (e.g., by "expanding" them), generates an intermediate "bridge frame" (such as a solid color frame), and then sequentially displays the modified frames and bridge frame to create the illusion of depth (’922 Patent, col. 15:5-32; Claim 1).
  • Technical Importance: This system provides a method for processing standard 2D video into a 3D-viewable format that is adaptable to various display technologies and does not require permanent alteration of the source media (’922 Patent, col. 7:45-53).

Key Claims at a Glance

  • The complaint asserts infringement of claims 1-12, which include independent apparatus claims 1, 5, 7, 9, and 11 (Compl. ¶15).
  • Independent Claim 1 recites an apparatus with the following essential elements:
    • A storage adapted to store image frames.
    • A processor adapted to:
      • Obtain a first and second image frame from a video stream.
      • Generate a first modified image frame by "expanding" the first image frame.
      • Generate a second modified image frame by "expanding" the second image frame.
      • Generate a "bridge frame" that is a solid color and different from the source frames.
      • Sequentially display the first modified image frame, the bridge frame, and the second modified image frame.
  • The complaint reserves the right to assert additional claims, including dependent claims (Compl. ¶15).

III. The Accused Instrumentality

Product Identification

  • The complaint does not identify any specific accused products, models, or services by name. It refers generally to "systems, products, and services in the field of motion pictures" that are maintained, operated, and administered by Panasonic (Compl. ¶8, 15).

Functionality and Market Context

  • The complaint does not describe the technical operation or features of any specific Panasonic product. Its allegations of functionality are framed in conclusory terms that mirror the language of the patent claims, such as alleging the existence of a "system comprising a storage adapted to store one or more image frames and a processor adapted to obtain a first image frame" (Compl. ¶10, 17). No allegations regarding the specific commercial importance or market position of any accused instrumentality are provided.

Visual Evidence

  • No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint states that support for its infringement allegations can be found in "preliminary exemplary table[s] attached as Exhibit B" for the '380 Patent and "Exhibit D" for the '922 Patent (Compl. ¶9, 16). However, these exhibits were not filed with the complaint. As a result, the complaint provides only a high-level narrative theory of infringement without specific element-by-element mapping.

The narrative theory alleges that Panasonic's unspecified "systems, products, and services" perform the methods and embody the apparatuses claimed in the patents-in-suit. Specifically, the complaint alleges that these systems acquire video frames, modify them, and display them in a manner that infringes claims 1-30 of the '380 Patent and claims 1-12 of the '922 Patent (Compl. ¶8, 15).

  • Identified Points of Contention:
    • Factual Specificity: A primary question for the court will be whether the complaint's broad and conclusory allegations, which fail to identify a single accused product or provide the referenced claim charts, satisfy the plausibility pleading requirements established by federal court precedent.
    • Technical Questions: Without identification of an accused product or its method of operation, it is not possible to identify specific technical disputes. The central technical question remains open: what evidence does the complaint provide that any Panasonic product actually performs the specific video manipulation steps required by the claims, such as "expanding" a frame or generating a "bridge frame"?

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for a definitive analysis of claim construction disputes. However, based on the claim language, the following terms may become central to the case.

The Term: "bridge frame"

  • Context and Importance: This term appears in the independent claims of both the '380 and '922 patents and is fundamental to the claimed process of creating a sequence of modified images. The definition of what constitutes a "bridge frame" will be critical to determining whether an accused system that, for example, inserts a blank screen or pause between frames meets this limitation.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification suggests a "bridge frame" could be a "solid black picture, a solid colored picture, or a timed unscreen pause," which may support a broad definition covering various forms of intermediate content or lack thereof (’380 Patent, col. 16:51-53).
    • Evidence for a Narrower Interpretation: Claim 1 of the '380 Patent recites that the bridge frame has "first and second opposing sides defining a first dimension and third and fourth opposing sides defining a second dimension." This language could support a narrower construction requiring a distinct, generated image with specific structural properties, not merely a temporal gap.

The Term: "expanding the... image frame"

  • Context and Importance: This active step is recited in the independent claims of both asserted patents. Its construction is key to the infringement analysis, as the parties will likely dispute what specific type of digital video processing qualifies as "expanding."
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patents do not appear to provide an explicit definition of "expanding." Plaintiff may argue the term should be given its plain and ordinary meaning, potentially encompassing a wide range of digital modifications that alter a frame, such as zooming, scaling, or stretching.
    • Evidence for a Narrower Interpretation: The patents distinguish "expanding" from other modification types like "shrinking" and "stitching" that are recited in other claims not asserted in the complaint (’922 Patent, Claim 7). A defendant could argue that "expanding" must therefore mean something specific and distinct from these other processes, limiting its scope to a particular kind of geometric or temporal alteration necessary for the 3D effect.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges both induced and contributory infringement. The allegations are based on assertions that Defendant "actively encouraged or instructed" its customers on how to use the infringing systems and services (Compl. ¶10, 11, 17, 18). The complaint does not cite specific evidence, such as user manuals, marketing materials, or technical support documents, to support these claims.
  • Willful Infringement: Willfulness is alleged based on Defendant’s knowledge of the patents-in-suit "from at least the filing date of the lawsuit" (Compl. ¶10, 17). This allegation, if proven, would only support a finding of post-filing willful infringement, as no facts are alleged to support pre-suit knowledge.

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

  • A central threshold issue will be one of pleading sufficiency: does the complaint’s failure to identify any specific accused products or provide the referenced evidentiary exhibits meet the federal standard for pleading a plausible claim of patent infringement, or is it subject to dismissal for lack of factual specificity?
  • A key evidentiary question will be one of technical correlation: if the case proceeds, the dispute will turn on whether Plaintiff can produce evidence demonstrating that the actual, technical operation of an identified Panasonic product performs the specific, multi-step video processing sequences recited in the claims, particularly the generation of a "bridge frame" and the "expanding" of source frames.
