  • Plaintiff’s Counsel: Ramey LLP
• Case Identification: 7:24-cv-00187, W.D. Tex., 10/11/2024
• Venue Allegations: Plaintiff alleges venue is proper in the Western District of Texas because Defendant maintains a regular and established place of business in the district and has committed acts of infringement there.
• Core Dispute: Plaintiff alleges that Defendant’s products and services related to electronic image stabilization for smart phones infringe a patent concerning methods for modifying an image to create an illusion of motion or depth.
• Technical Context: The technology relates to digital image processing, specifically techniques for generating additional video frames or modifying existing ones to alter the viewer's perception of motion and dimensionality, a process relevant to 2D-to-3D conversion and video enhancement.
• Key Procedural History: The complaint states that Plaintiff is a non-practicing entity and that it and its predecessors have entered into settlement licenses with other entities in prior disputes. Plaintiff contends these prior settlements do not trigger patent marking requirements under 35 U.S.C. § 287 because they were not licenses to produce a patented article.

Case Timeline

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 challenges in creating a convincing 3D visual effect (the "Pulfrich illusion") from standard 2D motion pictures. Conventional methods, such as using spectacles with one darkened lens, are often static and cannot dynamically adjust to changes in motion or lighting within the video, while more advanced electronic spectacles may suffer from issues like flicker or slow transition times between tint states (’380 Patent, col. 3:25-42). The patent also addresses the general problem of creating an illusion of continuous motion from a limited number of still images (’380 Patent, col. 8:50-63).
• The Patented Solution: The invention proposes a method for modifying a sequence of image frames by generating new, intermediate "bridge frames" and blending them with the original frames. This technique is designed to create a smoother, more continuous, or dimensionally altered visual experience. For example, a "bridge frame" could be a solid color or a composite of other frames, which, when inserted between two primary image frames, creates an appearance of movement or depth (’380 Patent, col. 9:7-13, col. 112:47-67). While the patent title references spectacles, the claims are directed more broadly to methods of generating a modified video.
• Technical Importance: The described methods offer a way to generate enhanced visual effects, such as simulated 3D, from conventional 2D video sources, potentially avoiding the need for specialized stereoscopic cameras and production equipment (’380 Patent, col. 22:49-54).

Key Claims at a Glance

• The complaint asserts infringement of claims 1-30 (’380 Patent, col. 112:55 - col. 116:31; Compl. ¶8).
• Independent Method Claim 1:
  • Acquiring a source video comprised of a sequence of image frames.
  • Identifying a first image frame and a second image frame from the sequence.
  • Generating a first modified image frame by expanding the first image frame.
  • Generating a second modified image frame by expanding the second image frame.
  • Generating a modified combined image frame from the two modified image frames, where the combined frame has first/third and second/fourth opposing sides that define a first and second dimension.
• Independent Apparatus Claim 9:
  • An apparatus comprising a storage medium with image frames and a processor.
  • The processor is adapted to identify first and second image frames.
  • The processor is adapted to expand the first and second frames to generate first and second modified image frames.
  • The processor is adapted to combine the modified frames to generate a modified combined image frame.
  • The processor is adapted to further generate a bridge frame, where the first modified image frame, the second modified image frame, and the bridge frame are different.
  • The processor is adapted to blend the modified combined image frame with the bridge frame.
• The complaint reserves the right to assert dependent claims (Compl. ¶8).

III. The Accused Instrumentality

Product Identification

The complaint identifies the accused instrumentalities broadly as "systems, products, and services in the field of electronic image stabilization for smart phones and related products" maintained, operated, and administered by Defendant MediaTek (Compl. ¶8).

Functionality and Market Context

The complaint does not specify any particular MediaTek products (e.g., specific chipset models or software libraries) or describe their technical operation. The allegations are limited to the general category of "electronic image stabilization," a technology commonly used in smartphone cameras to reduce blur caused by camera shake during photo or video capture (Compl. ¶8). The complaint does not provide further detail on the functionality or market context of the accused instrumentalities.

IV. Analysis of Infringement Allegations

The complaint references a "preliminary exemplary table attached as Exhibit B" to support its infringement allegations; however, this exhibit was not included with the filed complaint (Compl. ¶9). As such, the infringement theory must be inferred from the narrative allegations, which state that Defendant's "electronic image stabilization" technology infringes one or more claims of the ’380 Patent (Compl. ¶8). The complaint does not provide specific facts explaining how the accused technology meets the limitations of any asserted claim.

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Technical Questions: A central question will be whether the function of "electronic image stabilization," which typically involves cropping, rotating, or shifting video frames to counteract motion, performs the specific, multi-step process recited in the claims. For instance, what evidence will show that this technology "generates" and "blends" a "bridge frame" with a "modified combined image frame" as required by claims like Claim 9?
  • Scope Questions: The dispute may turn on whether the accused technology, designed to reduce the visual effect of motion, can be said to practice a claimed method whose apparent purpose is to create an illusion of motion or depth. The complaint does not provide facts to bridge this potential gap in functionality.

V. Key Claim Terms for Construction

• The Term: "bridge frame" (Claim 2)

• Context and Importance: This term appears to be a neologism central to the patent's inventive concept. Its construction will be critical for determining the scope of infringement, as the complaint does not explain what feature of the accused "electronic image stabilization" constitutes a "bridge frame."

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification suggests a "bridge-type picture may be simply a solid-colored picture" or that it can be a "bridging picture which is dissimilar to said image pictures," implying it need not be complex (’380 Patent, col. 8:63-64, col. 9:8-9).
  • Evidence for a Narrower Interpretation: The patent also describes more specific embodiments, where the bridge frame is formed by blending or combining portions of other frames, suggesting a more constrained definition tied to creating a specific visual sequence or illusion (’380 Patent, col. 9:25-36).

• The Term: "expanding" (Claim 1)

• Context and Importance: The method of Claim 1 requires "expanding" the first and second image frames to generate modified frames. How this term is defined will be key, as electronic image stabilization often involves cropping (i.e., reducing) an image from a larger sensor capture, not necessarily "expanding" it.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent does not appear to provide an explicit definition, which may support an argument for applying its plain and ordinary meaning.
  • Evidence for a Narrower Interpretation: The context of creating a "modified combined image frame" with distinct dimensions from two expanded frames may suggest a specific type of digital manipulation beyond simple scaling, potentially limiting its scope (’380 Patent, col. 112:64 - col. 113:2).

VI. Other Allegations

• Indirect Infringement: The complaint does not include a formal count for indirect infringement. However, it alleges that "but for Defendant's actions, the claimed-inventions embodiments... would never have been put into service," which suggests a possible, though undeveloped, theory of inducement or contributory infringement (Compl. ¶8). The complaint provides no specific facts regarding Defendant's alleged knowledge or intent to encourage infringement by others.
• Willful Infringement: The complaint does not explicitly allege willful infringement or plead facts to support a finding of willfulness, such as pre-suit knowledge of the patent. The prayer for relief, however, requests that the case be declared "exceptional" under 35 U.S.C. § 285, a remedy often tied to findings of willful infringement or litigation misconduct (Compl., Prayer for Relief d.).

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

1. Evidentiary Sufficiency: The primary issue is whether the complaint’s sparse allegations, which identify only a general field of technology ("electronic image stabilization"), can survive a motion to dismiss. A key question for the court will be whether these allegations provide plausible, non-conclusory factual content linking a specific accused product to the detailed steps of the asserted claims.

2. Technical Congruence: A fundamental question will be one of functional mismatch: can Plaintiff demonstrate that "electronic image stabilization," a technology aimed at compensating for and neutralizing unwanted camera movement, actually performs the claimed methods of generating and blending "bridge frames" for the purpose of creating a perceptual illusion of motion or depth?

3. Definitional Scope: The case will likely hinge on the construction of core claim terms like "bridge frame" and "expanding". A central question is whether these terms, as defined by the patent's specification, can be construed broadly enough to read on the operations performed by the accused image stabilization technologies, or if they are limited to the patent’s specific disclosed purpose of creating 3D-like visual effects.
