Case Timeline

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

U.S. Patent No. 7,277,572 - "Three-Dimensional Interior Design System"

The Invention Explained

• Problem Addressed: The patent describes the state of interior design software in the early 2000s as limited. Existing systems either used simple 2D images, or if they used 3D objects, they could not be effectively manipulated in real-time within a 3D model of a room on a user's local computer. This often required sending data to a server for rendering, which introduced time lags and a disjointed user experience (ʼ572 Patent, col. 3:58-4:19).
• The Patented Solution: The invention proposes a client-server system that improves this process. A user operates a "client application" on their local computer, which can retrieve 3D objects (e.g., furniture) from a remote server. The key is that the client application itself is capable of importing these objects into a 3D scene, allowing the user to manipulate them (e.g., move, rotate, scale) in real-time, and rendering a "photorealistic" composite image directly on the client device (ʼ572 Patent, Abstract; col. 4:19-24). This client-side processing is intended to provide a faster and more interactive design experience.
• Technical Importance: The described technical approach sought to shift the computational load of real-time manipulation and rendering from a remote server to the user's local machine, thereby reducing latency and enabling a more fluid and realistic visualization process for interior design (ʼ572 Patent, col. 4:19-24).

Key Claims at a Glance

• The complaint primarily asserts independent claim 1.
• The essential elements of claim 1, a method, include:
  • Communicably accessing a server with a client.
  • Operating a client application with a GUI for scene editing and rendering.
  • Displaying a 3D scene with the GUI.
  • Configuring the 3D scene to be displayed in multiple views.
  • Retrieving a 3D object from the server.
  • Importing the 3D object into the 3D scene to create a composite.
  • Manipulating the 3D object within the composite.
  • Rendering a 3D image of the composite at the client.
  • Selectively reconfiguring the 3D image in real time.
  • Applying luminosity characteristics to the 3D image.
  • Rendering a photorealistic 3D view of the composite image.
• The complaint’s prayer for relief seeks judgment on "one or more claims," preserving the right to assert other claims (Compl. ¶55a).

III. The Accused Instrumentality

Product Identification

The "Augmented Reality" tool and related features available on Defendant's website (www.homedepot.com) and its downloadable iOS mobile application (the "Accused Products") (Compl. ¶30).

Functionality and Market Context

The Accused Products allow a user to select an item for sale, such as a light fixture, and activate a feature to "See it in your home with 3D Augmented Reality" (Compl. ¶30, Fig. 2). This function uses the camera of the user's mobile device to display a live feed of their physical space and overlays a 3D model of the selected product onto that feed (Compl. ¶44, Fig. 5). The complaint includes screenshots showing that users can then manipulate the 3D model, for instance by pinching to change its scale within the augmented reality view (Compl. Fig. 7). The complaint alleges Defendant markets this as a key feature to help customers "make better buying decisions" by visualizing items in their space (Compl. ¶33).

IV. Analysis of Infringement Allegations

'572 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: A principal dispute may arise over the meaning of "3D scene". The patent specification describes creating scenes by, for example, drawing floor plans and walls (ʼ572 Patent, col. 13:12-24). This raises the question of whether the live video feed of a physical room, as used by the Accused Products, constitutes a "3D scene" as contemplated by the patent.
• Technical Questions: The complaint alleges the final two steps of claim 1—applying "luminosity characteristics" and rendering a "photorealistic" view—are met. The patent links these terms to specific, complex lighting and shadow simulations (ʼ572 Patent, col. 7:12-17; Table 5). A technical question will be what evidence demonstrates that the Accused Products perform these specific computational functions, beyond simply displaying a pre-shaded 3D model with basic lighting.

V. Key Claim Terms for Construction

The Term: "3D scene"

• Context and Importance: This term's construction is fundamental to the infringement analysis. If "3D scene" is construed to require a computer-generated model of a room (with defined walls, floor, etc.), then infringement by a system using a live camera feed of an un-modeled physical space may be more difficult to establish. Practitioners may focus on this term because it represents a potential mismatch between the patent's descriptive examples and the technology of the Accused Products.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself does not specify how the "3D scene" must be generated. One might argue that any representation of a three-dimensional space, including one captured by a camera for the purpose of placing 3D objects, falls within the plain meaning of the term.
  • Evidence for a Narrower Interpretation: The specification repeatedly describes generating a scene by "planning" a room, using "room templates," and creating "floor," "ceiling," and "wall plans" (ʼ572 Patent, col. 13:1-11; Fig. 5). The patent also criticizes prior art where room images "were not associated with a 3-D model of the room," suggesting the inventors contemplated a structured, modeled environment rather than a simple photographic overlay (ʼ572 Patent, col. 3:58-61).

The Term: "photorealistic 3D view"

• Context and Importance: The "photorealistic" quality of the final rendered image is a required outcome of the claimed method. The definition of this term will determine the standard of quality and computational complexity the accused system must achieve to infringe.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The term is not explicitly defined with a threshold. Plaintiff may argue it simply means an image that appears realistic to a user, as opposed to a wireframe or schematic, and that the screenshots in the complaint meet this standard (Compl. Fig. 5).
  • Evidence for a Narrower Interpretation: The specification links "photorealistic" rendering to the application of advanced effects, including "luminosity characteristics", "ray tracing", "radiosity", and "shadow effects" (ʼ572 Patent, col. 5:35-36; col. 15:3-10). Defendant may argue that to be "photorealistic" in the context of the patent, a system must perform these specific, complex lighting calculations, not merely display a shaded object.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant encourages and instructs its customers to use the Accused Products in an infringing manner through its advertising and user guides (Compl. ¶46). The complaint provides a screenshot of the app's instructions as evidence of this guidance (Compl. Fig. 4). Contributory infringement is also alleged on the basis that the Accused Products have special features for infringement with no substantial non-infringing use (Compl. ¶47).
• Willful Infringement: The willfulness claim is based on Defendant’s alleged knowledge of the patent since at least the filing of the complaint and on an alleged "policy or practice of not reviewing the patents of others," which Plaintiff characterizes as willful blindness (Compl. ¶48-51).

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

• A core issue will be one of definitional scope: can the patent’s term "3D scene", which the specification heavily implies is a constructed virtual room model, be construed to cover the live, un-modeled camera feed of a physical environment used by the accused augmented reality system?
• A second central question will be one of functional performance: does the accused tool’s display of a 3D model in a camera view meet the claim requirements of "applying luminosity characteristics" and rendering a "photorealistic" view, as those functions are described in the patent, or is there a fundamental mismatch in the technical operations being performed? The outcome may depend on whether these terms require complex, real-time lighting simulation or can be satisfied by displaying a pre-rendered 3D object.
