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

U.S. Patent No. 9,699,444 - "Faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials"

• Patent Identification: U.S. Patent No. 9,699,444, "Faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials," issued July 4, 2017.

The Invention Explained

• Problem Addressed: The patent family addresses the technical challenge of creating a convincing 3D stereoscopic effect when viewing standard 2D movies. This is often achieved using the "Pulfrich illusion," where darkening one eye's lens causes the brain to perceive lateral motion as depth (’304 Patent, col. 7:45-54). A key problem is that the variable tint materials used in electronic glasses can have slow "transition times" between light and dark states, hindering synchronization with fast-moving scenes (’235 Patent, col. 2:25-30).
• The Patented Solution: The ’444 Patent, as described in the complaint, claims an apparatus (such as a television) that processes video to facilitate this 3D effect. The solution involves a processor that generates a "modified image frame" from an original video stream and also generates a "bridge frame," which is described as a solid color frame inserted between video frames (Compl. ¶12). This processed video stream, when viewed with synchronized glasses, is intended to produce the desired 3D effect. The broader patent family suggests using multi-layered lens materials to achieve faster state transitions in the viewing spectacles (’235 Patent, col. 1:8-13).
• Technical Importance: This technology sought to enable 3D viewing for any standard 2D movie, greatly expanding the available 3D content beyond specially filmed productions and potentially increasing the value of consumer 3D-capable televisions.

Key Claims at a Glance

• The complaint asserts independent claim 26 (Compl. ¶14).
• Based on the complaint's summary of a claimed embodiment, the essential elements of the apparatus claim are (Compl. ¶12):
  • A storage adapted to store one or more image frames.
  • A processor adapted to:
    • obtain a first image frame from a first video stream;
    • generate a modified image frame by performing actions such as expanding, shrinking, or reshaping the first image frame;
    • generate a solid color bridge frame that is different from the first and modified image frames;
    • display the modified image frame; and
    • display the bridge frame.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

U.S. Patent No. 9,716,874 - "Continuous adjustable 3Deeps Filter Spectacles for optimized 3Deeps stereoscopic viewing, control method and means therefor, and system and method of generating and displaying a modified video"

• Patent Identification: U.S. Patent No. 9,716,874, "Continuous adjustable 3Deeps Filter Spectacles for optimized 3Deeps stereoscopic viewing, control method and means therefor, and system and method of generating and displaying a modified video," issued July 25, 2017.

The Invention Explained

• Problem Addressed: The invention addresses the same technical problem as the ’444 Patent: generating a 3D effect from 2D video content. This patent focuses on the specific method of video manipulation required to create the illusion of depth and motion.
• The Patented Solution: The patented solution is a method of generating and displaying modified video. The method comprises acquiring a source video, modifying an image frame from that video, and then generating two different "altered" image frames that contain distinct "non-overlapping portions" of the modified frame (Compl. ¶24). This process of creating and displaying frames with specifically arranged portions is intended to generate the visual effect of continuous motion and depth when viewed by a user.
• Technical Importance: This method provides a specific process for manipulating standard video frames to create novel visual effects, aiming to produce a more fluid and convincing illusion of three dimensions than simple frame repetition or alternation.

Key Claims at a Glance

• The complaint asserts independent claim 1 (Compl. ¶26).
• The essential steps of the method claim are (Compl. ¶24):
  • acquiring a source video comprising a sequence of image frames;
  • obtaining a first image frame from the source video;
  • generating a modified image frame by performing one of: expanding the first image frame, removing a first portion of it, or stitching it with a portion of a second frame;
  • generating a first altered image frame that includes first and second non-overlapping portions; and
  • generating a second altered image frame that includes third and fourth non-overlapping portions, where the constituent portions are different from those in the first altered frame.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

Multi-Patent Capsule: U.S. Patent No. 8,864,304

• Patent Identification: "Continuous adjustable 3Deeps Filter spectacles for optimized 3Deeps stereoscopic viewing and its control method and means," issued October 21, 2014.
• Technology Synopsis: This patent claims the electronically controlled spectacles used to view the modified video content. The invention comprises a spectacle frame housing optoelectronic lenses that can be independently controlled to switch between a "dark state and a light state" by a control unit also housed in the frame (Compl. ¶38). This differential tinting between the left and right eyes is the mechanism that generates the Pulfrich stereoscopic 3D illusion.
• Asserted Claims: Claim 1 (Compl. ¶40).
• Accused Features: Sony’s active 3D glasses, which feature a frame, lenses that alternate states, and an IR sensor to receive control signals, are accused of infringement (Compl. ¶42-45).

Multi-Patent Capsule: U.S. Patent No. 9,167,235

• Patent Identification: "Faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials," issued October 20, 2015.
• Technology Synopsis: This patent is also directed to the electronically controlled spectacles, with a focus on improving performance. It claims spectacles whose lenses have a "plurality of states" and are independently controlled (Compl. ¶50). The patent family specification indicates that using multi-layered variable tint materials allows the lenses to transition more quickly between optical states, which is critical for maintaining a clear 3D effect during fast-paced scenes (’304 Patent, col. 1:37-45).
• Asserted Claims: Claim 1 (Compl. ¶52).
• Accused Features: Sony’s active 3D glasses, which are electronically controlled and feature lenses that shift between transparent and opaque states, are accused of infringement (Compl. ¶53, ¶55-57).

III. The Accused Instrumentality

• Product Identification: The accused instrumentalities are Sony televisions (represented by the Sony X850D and 55X930E series) and Sony Active 3D Glasses (represented by model TDG-BR100) (Compl. ¶14, ¶26, ¶40).
• Functionality and Market Context:
  • The complaint alleges the accused Sony TVs are "Smart TVs" that include storage, a processor, and various video inputs (Compl. ¶15, ¶16). The complaint identifies three specific functionalities relevant to the infringement allegations. First, the TVs perform "upscaling," which expands lower-resolution input video frames to the TV's native 4K resolution (Compl. ¶17). Second, they utilize "black frame insertion" (BFI), a technique that inserts a solid black frame between displayed image frames to reduce motion blur (Compl. ¶18). The complaint includes a graph from a third-party review site showing the luminosity pattern of the TV's backlight during BFI operation (Compl. p. 9). Third, the TVs feature "MotionFlow" technology, which inserts additional, interpolated frames between original video frames to create smoother motion (Compl. ¶30-31).
  • The accused Sony Active 3D Glasses are electronically controlled spectacles that "automatically synchronize with Sony 3D TV's" (Compl. ¶41). They contain an IR sensor to receive signals from a transmitter connected to the TV, which controls the state of each lens independently to alternate between light and dark states (Compl. ¶43-45).

IV. Analysis of Infringement Allegations

The complaint does not attach the asserted patents U.S. 9,699,444 or U.S. 9,716,874. Therefore, a side-by-side claim chart analysis referencing the patent specification's support for claim terms is not possible based on the provided documents. The narrative infringement theories are summarized below.

’444 Patent Infringement Allegations (Prose Summary)

The complaint alleges that the accused Sony TVs meet the limitations of claim 26 of the ’444 Patent. The TV's internal memory is alleged to be the claimed "storage" (Compl. ¶15). The TV's processor is alleged to obtain a video frame via its inputs and generate a "modified image frame" by performing upscaling, which expands the frame to the screen's 4K resolution (Compl. ¶16-17). The complaint alleges that the TV's "black frame insertion" (BFI) feature generates the claimed "solid color bridge frame" (Compl. ¶18). Finally, it alleges the TV processor is adapted to display both the upscaled (modified) frame and the black (bridge) frame (Compl. ¶19). A timing diagram from a third-party review shows the TV's backlight pattern periodically dropping to zero luminosity, which the complaint presents as evidence of the displayed black frame (Compl. p. 9).

’874 Patent Infringement Allegations (Prose Summary)

The complaint alleges that the accused Sony TVs perform the method of claim 1 of the ’874 Patent. The method begins by "acquiring a source video" through inputs like HDMI (Compl. ¶27) and "obtaining a first image frame," such as a 1080i frame from a cable box (Compl. ¶28). The TV allegedly "generates a modified image frame" by upscaling it to 4K resolution (Compl. ¶29). The core of the allegation is that the TV's "MotionFlow" feature generates the claimed "altered image frames." The complaint uses diagrams from a Sony marketing website to illustrate how inserting new frames creates what it labels as "first and second non-overlapping portions" and "third and fourth non-overlapping portions" of the modified image frame, thereby mapping the product's function to the specific claim language (Compl. ¶30-33). The complaint includes annotated diagrams that break down an interpolated frame to identify these alleged "non-overlapping portions" (Compl. pp. 15-16).

Identified Points of Contention

• Scope Questions: A primary question for the ’444 Patent may be whether the term "bridge frame," as defined and used within that patent's specification, can be construed to read on the function of "black frame insertion," a widely known technique for motion blur reduction. Similarly, for the ’874 Patent, a central issue may be whether the frame interpolation process of "MotionFlow" technology results in "altered image frames" containing "non-overlapping portions" as those terms are technically defined by the patent, or if this represents a mischaracterization of how the accused technology operates.
• Technical Questions: A key technical question for the ’444 Patent is what evidence demonstrates that the purpose and operation of BFI in the accused TVs is the same as that of the "bridge frame" claimed in the patent. For the ’874 patent, a factual question is how Sony's MotionFlow algorithm actually constructs interpolated frames and whether this process technically aligns with the claim steps of generating frames from "non-overlapping portions" of a modified source frame, as the complaint's annotated diagrams suggest (Compl. pp. 15-16).

V. Key Claim Terms for Construction

Analysis of intrinsic evidence is limited, as the ’444 and ’874 patents are not attached to the complaint. The analysis is based on language in the complaint and the provided patents from the same family.

• The Term: "bridge frame" (’444 Patent)

• Context and Importance: This term is critical, as the complaint's infringement theory for the ’444 Patent equates Sony's "black frame insertion" feature with the claimed "bridge frame" (Compl. ¶18). The viability of this infringement count may depend on whether the term is construed broadly to cover any inserted solid color frame or more narrowly to a frame with a specific purpose or relationship to the surrounding frames as described in the (unseen) specification.

• Intrinsic Evidence for Interpretation: The complaint alleges the claim requires the bridge frame to be a "solid color" (Compl. ¶12). The broader patent family discusses inserting "dissimilar bridge frames" between "similar image frames" to create visual illusions (’235 Patent, Claim 10). This context from a related patent suggests a "bridge frame" may be an element used to create a specific perceptual effect, a point that could support a narrower construction than simply any black frame inserted for motion blur reduction.

• The Term: "non-overlapping portions" (’874 Patent)

• Context and Importance: This term is foundational to the infringement theory against Sony's "MotionFlow" technology. The complaint alleges that this feature generates "altered image frames" composed of such portions (Compl. ¶31-33). Practitioners may focus on this term because frame interpolation is typically a process of creating new pixel data based on surrounding frames, not necessarily selecting and recombining discrete "portions" of a prior frame.

• Intrinsic Evidence for Interpretation: The complaint's description of claim 1 recites that a "first altered image frame... includes first and second non-overlapping portions" and a "second altered image frame... includes third and fourth non-overlapping portions" (Compl. ¶24). Without the specification, it is an open question whether this language implies a simple cutting-and-pasting of image sections, as the complaint's diagrams suggest (Compl. pp. 15-16), or if it describes a more complex relationship between the frames that may or may not align with the accused interpolation technology.

VI. Other Allegations

• Indirect Infringement: The complaint includes boilerplate allegations of indirect infringement under 35 U.S.C. § 271(b) and (c) for all four patents-in-suit (Compl. ¶21, ¶35, ¶47, ¶59). However, it does not plead specific facts to support the requisite knowledge and intent for inducement or contributory infringement, such as references to user manuals or advertising that instruct on infringing use.

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

• A core issue will be one of technical mapping: can video processing techniques widely used in the television industry for purposes like motion blur reduction ("black frame insertion") and motion smoothing ("MotionFlow") be mapped onto the specific claim limitations of a "bridge frame" and frames with "non-overlapping portions," or is there a fundamental mismatch in technology and purpose? The complaint’s reliance on marketing diagrams (Compl. pp. 15-16) to prove technical infringement will likely be a central point of contention.
• A second key question will be one of patent viability: given the subsequent cancellation of asserted claim 26 of the ’444 Patent in an ex parte reexamination, a threshold issue will be whether the infringement claim based on that patent can survive, potentially narrowing the scope of the dispute to the remaining three patents.
• A third question will be one of claim scope: for the patents directed to the 3D glasses (’304 and ’235 Patents), the dispute may turn on whether the claims, when construed in light of their specifications, are broad enough to cover standard active shutter glasses or contain limitations related to the specific ‘3Deeps’ Pulfrich-effect system that differentiate them from the accused products.
