VDPP LLC v. Home Depot USA Inc

I. Executive Summary and Procedural Information

• Parties & Counsel:
  • Plaintiff: VDPP, LLC (Oregon)
  • Defendant: Home Depot USA., Inc. (Delaware)
  • Plaintiff’s Counsel: Ramey LLP
• Case Identification: 2:26-cv-00049, E.D. Tex., 01/22/2026
• Venue Allegations: Plaintiff alleges venue is proper because Defendant has regular and established places of business in the district, conducts substantial business there, and has committed acts of infringement in the district.
• Core Dispute: Plaintiff alleges that Defendant’s unspecified image processing and image capture systems, products, and services infringe two expired patents related to methods for creating illusions of three-dimensional motion.
• Technical Context: The technology concerns digital image processing techniques used to create an appearance of sustained, continuous motion and depth from a limited number of two-dimensional images.
• Key Procedural History: The complaint states that both patents-in-suit have expired. Plaintiff, a non-practicing entity, notes it has entered into prior settlement licenses and argues at length that these licenses do not trigger marking requirements under 35 U.S.C. § 287(a) because they did not involve admissions of infringement or authorize the production of patented articles.

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

U.S. Patent No. 7,030,902 - "Eternalism, a method for creating an appearance of sustained three-dimensional motion-direction of unlimited duration, using a finite number of pictures"

The Invention Explained

• Problem Addressed: The patent addresses the challenge of creating a visual illusion of continuous, sustained motion in a specific direction using only a finite, and often small, number of pictures, which traditional filmmaking and animation techniques could not achieve without visible repetition or "stutter" ’902 Patent, col. 1:22-29 ’902 Patent, col. 7:17-24
• The Patented Solution: The invention proposes a method where at least two visually similar image pictures (e.g., frames 'A' and 'B') are arranged sequentially with a third, visually dissimilar "bridging picture" (e.g., a solid black frame 'C') ’902 Patent, col. 2:15-27 This A-B-C sequence is then repeated in a continuous loop. The viewer's brain interprets the flicker and the slight shift between the similar images, separated by the bridging frame, as uninterrupted, ongoing motion rather than a simple loop ’902 Patent, abstract ’902 Patent, col. 2:42-52 The patent also describes enhancing this effect by blending adjacent pictures (e.g., creating A/B, B/C, C/A frames) to create a more fluid illusion ’902 Patent, col. 2:56-67
• Technical Importance: This method provided a novel artistic and technical tool for generating complex visual effects of perpetual motion and illusionary depth from minimal source material, a departure from traditional frame-by-frame animation or live-action capture ’902 Patent, col. 1:13-21

Key Claims at a Glance

The complaint asserts claims 1-11 Compl. ¶9 Independent claim 1 includes the following essential elements:

• selecting at least two image pictures, a first image picture and a second image picture, which are visually similar;
• selecting a bridging picture which is dissimilar to said image pictures;
• arranging said pictures in a sequential order to create a first series of pictures, said sequential order being one or more first image pictures, one or more second image pictures, and one or more bridging pictures;
• placing said first series of pictures on a plurality of picture frames wherein each picture of said first series is placed on a single frame; and
• repeating the first series of pictures a plurality of times to create a continuous plurality of picture frames... such that when said plurality of picture frames are viewed, an appearance of continuous movement is perceived by a viewer.

U.S. Patent No. 9,948,922 - "Faster state transitioning for continuous adjustable 3Deeps filter spectacles using multi-layered variable tint materials"

The Invention Explained

• Problem Addressed: While the patent title and sections of the specification focus on 3D spectacles that use the "Pulfrich effect," the asserted claims are directed to a distinct but related problem in image processing. The complaint alleges the patent is directed to capturing, modifying, and displaying image frames to create a combined visual output Compl. ¶13 This aligns with apparatus claims in the patent that describe a system for generating visual effects, separate from the spectacles themselves ’922 Patent, col. 113:24-114:47
• The Patented Solution: The invention claimed in the asserted apparatus claims involves a processor and storage system ’922 Patent, col. 113:25-28 The processor is adapted to obtain image frames from a video stream, generate modified frames by applying transformations such as expanding, shrinking, or stitching, generate a separate "bridge frame" that is a solid color, and then display the modified frames and the bridge frame sequentially ’922 Patent, col. 113:29-114:23 This system provides a concrete apparatus-based implementation of the "Eternalism" method described in the ’902 patent.
• Technical Importance: The claimed apparatus provides a specific system architecture for automating the creation of video effects that rely on frame modification and sequential display with bridging intervals, grounding the conceptual method in a tangible processing system ’922 Patent, col. 57:26-58:24

Key Claims at a Glance

The complaint asserts claims 1-12 Compl. ¶14 Independent claim 1 recites an apparatus with the following essential elements:

• a storage adapted to store one or more image frames;
• a processor adapted to obtain a first image frame and a second image frame from a first video stream;
• the processor is adapted to generate a first modified image frame by expanding the first image frame... a second modified image frame by expanding the second image frame;
• the processor is adapted to generate a bridge frame, wherein the bridge frame is a solid color;
• the processor is adapted to display the first modified image frame, display the second modified image frame, and display the bridge frame.

III. The Accused Instrumentality

Product Identification

The complaint does not identify any specific accused products, methods, or services by name Compl. ¶¶9, 14

Functionality and Market Context

• The complaint alleges in general terms that Defendant "maintains, operates, and administers systems, products, and services in the field of image processing" that infringe the ’902 patent Compl. ¶9 For the ’922 patent, it alleges infringement by "systems, products, and services in the field of image capture and modification" Compl. ¶14
• The complaint does not provide any technical details about the functionality of the accused instrumentalities or their market context. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint does not provide a narrative infringement theory or specific facts mapping claim elements to accused functionalities. It references preliminary claim charts in Exhibits B and D, which were not included with the complaint provided for analysis Compl. ¶¶10, 15 Therefore, a claim chart summary cannot be constructed.

Identified Points of Contention

• Pleading Sufficiency: A threshold issue for the court may be whether the complaint's generalized allegations against unspecified "systems, products, and services" provide sufficient factual detail to state a plausible claim for relief under the pleading standards established by Bell Atlantic Corp. v. Twombly and Ashcroft v. Iqbal.
• Technical Questions: Without identification of an accused product, it is not possible to frame specific technical questions. A central evidentiary challenge for the plaintiff will be to demonstrate, through discovery, that some instrumentality operated by the Defendant performs the specific steps of selecting similar frames, selecting a "dissimilar" bridge frame, and repeating them in a sequence as claimed in the ’902 patent, or contains the specific processor-and-storage architecture for modifying and displaying frames as claimed in the ’922 patent.

V. Key Claim Terms for Construction

"bridging picture which is dissimilar" (’902 Patent, claim 1)

• Context and Importance: The scope of this term is fundamental to the infringement analysis for the ’902 patent. The degree of "dissimilarity" required will determine what types of intermediate frames (e.g., black frames, solid color frames, high-contrast images) fall within the claim's scope. Practitioners may focus on this term because its interpretation could either limit the claim to the patent's preferred embodiment (a solid black frame) or broaden it to cover a wider range of video transition effects.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification suggests alternatives to a solid color, stating the bridge picture "may also be a strongly contrasting image-picture" ’902 Patent, col. 2:32-33 This language may support a construction that does not require the bridging picture to be devoid of image content, so long as it is sufficiently different from the primary images.
  • Evidence for a Narrower Interpretation: The patent repeatedly identifies the preferred embodiment of the bridging picture as "a solid black or other solid-colored picture" and a "neutral or black frame" ’902 Patent, col. 2:30-31 ’902 Patent, col. 2:54 A defendant may argue that these descriptions limit the scope of "dissimilar" to non-image or monochrome frames.

"generate a first modified image frame by expanding the first image frame" (’922 Patent, claim 1)

• Context and Importance: This term, and parallel terms like "shrinking" and "stitching" in dependent claims, defines the specific type of image processing the claimed apparatus must perform. The definition of "expanding" will be critical to determining infringement. If the accused product performs a type of image scaling or zooming, the parties will likely dispute whether that functionality meets this limitation.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent does not appear to provide an explicit definition of "expanding." A party might argue that the term should be given its plain and ordinary meaning in the context of digital image processing, which could encompass various forms of scaling, resizing, or digital zoom.
  • Evidence for a Narrower Interpretation: The specification discusses modifying frames in the context of creating specific "Eternalism" visual effects ’922 Patent, col. 51:40-52:21 A party could argue that "expanding" should be construed in light of these disclosed purposes, potentially limiting it to modifications that create the specific illusion of motion or depth described, rather than any generic image enlargement.

VI. Other Allegations

Willful Infringement

The complaint does not allege pre-suit knowledge of the patents-in-suit. Instead, it conditionally requests a finding of willfulness and treble damages "provided discovery reveals" that Defendant knew of the patents, infringed after gaining that knowledge, and knew or should have known its conduct was infringing Compl. ¶V.e

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

• A core procedural issue will be one of pleading sufficiency: does the complaint’s failure to identify a single accused product or provide any specific factual allegations of infringement meet the plausibility standard required to proceed to discovery?
• A central claim construction question will be one of definitional scope: how "dissimilar" must a "bridging picture" be under the ’902 patent? Can this term read on common video transitions, or is it limited to the solid-color frames emphasized in the specification?
• Should the case proceed, a key damages question will concern patent marking: has the plaintiff, by granting prior settlement licenses, created an obligation to ensure marking under 35 U.S.C. § 287(a), and if so, would a failure to comply limit the recovery of pre-suit damages?
