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

U.S. Patent No. 7,893,848 - "Apparatus and Method for Locating, Identifying and Tracking Vehicles in a Parking Area"

The Invention Explained

  • Problem Addressed: The patent’s background section describes the inefficiency of early parking guidance systems, which could only count the total number of cars entering and exiting a facility. This approach failed to guide drivers to specific vacant spaces and made it difficult for drivers to locate their own parked vehicles, leading to frustration and inefficient use of parking capacity (ʼ848 Patent, col. 1:20-41).
  • The Patented Solution: The invention solves this problem with a system of networked cameras that monitor individual parking spaces. An "Image Processing and Camera Control Unit" analyzes images from the cameras to determine occupancy for each space ('848 Patent, col. 3:41-53; Fig. 1). The system then provides this granular information to drivers via displays or other means to guide them to available spots, and can also be used to identify specific vehicles to help drivers find their cars ('848 Patent, col. 3:10-34).
  • Technical Importance: The technology represents a move beyond simple vehicle counting toward a more intelligent, image-based system that provides real-time, location-specific data for individual parking stalls, enabling a suite of value-added services ('848 Patent, col. 1:42-58).

Key Claims at a Glance

  • The complaint asserts infringement of claims 1-16, with independent claims 1, 4, 9, and 12. The complaint specifically references independent claim 4 as exemplary (Compl. ¶18).
  • The essential elements of independent claim 4 include:
    • A system comprising one or more first detection units and one or more display units.
    • The detection units determine the locations of vacant parking spaces, and the display units display those locations.
    • Each detection unit itself comprises:
      • One or more camera elements that repeatedly capture images of parking spaces.
      • One or more image processing units that process the images, resulting in "segmentation of the respective images into vehicle and non-vehicle objects."
      • One or more processors that identify "one or more features in the respective processed captured images, wherein each of the features are representative of a vehicle’s presence."
  • The complaint reserves the right to assert all claims from 1-16 (Compl. ¶18).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities include Defendant’s M4 Smart-Sensor, L4 Lightpipe Sensor, S1 Outdoor Solution, Sparx platform, Park Alerts, Park Finder, and Park Surveillance products, as well as the integrated parking guidance systems that incorporate them (Compl. ¶5).

Functionality and Market Context

The complaint alleges these products constitute "camera-based parking guidance systems" (Compl. ¶14). Their function is to provide parking guidance to drivers by monitoring parking spaces (Compl. ¶5). The complaint alleges Defendant has been in this market since 2005 and released its first camera sensors in 2010 (Compl. ¶14).

IV. Analysis of Infringement Allegations

The complaint references an exemplary claim chart in Exhibit 2, which allegedly compares independent claim 4 of the ’848 Patent to a parking guidance system incorporating Defendant's M4 Smart-Sensors (Compl. ¶18). This exhibit was not included with the filed complaint document. The complaint’s narrative theory is that the accused systems, including the M4 Smart-Sensor, perform all the functions required by the asserted claims, including capturing images of parking spaces, processing those images to determine vehicle presence, and displaying vacant spot locations to drivers (Compl. ¶¶5, 17-18). The complaint does not, however, provide specific factual detail in its body explaining how the accused products meet each claim element. No probative visual evidence provided in complaint.

  • Identified Points of Contention:
    • Technical Questions: The complaint’s allegations are stated at a high level. A central technical question for the court will be what evidence demonstrates that the accused systems perform the specific image processing steps recited in the claims. For example, the court will need to determine if the accused systems perform "segmentation of the respective images into vehicle and non-vehicle objects" and "identifying one or more features...representative of a vehicle's presence" ('848 Patent, col. 13:5-12), or if they use a technically distinct method to determine occupancy.
    • Scope Questions: The dispute may turn on the scope of the claimed image processing steps. A key question will be whether the accused system's method for detecting an object in a parking space falls within the claim language. For instance, if the accused system merely detects a sufficient change in pixels without identifying a "feature" of a "vehicle," it raises the question of whether this meets the claim limitation as properly construed.

V. Key Claim Terms for Construction

  • The Term: "identifying one or more features in the respective processed captured images, wherein each of the features are representative of a vehicle's presence" ('848 Patent, col. 13:9-12).

    • Context and Importance: The definition of this term is central to the infringement analysis. The case may depend on whether the accused system's method for determining occupancy meets this "identifying...features" requirement. Practitioners may focus on this term because it distinguishes the claimed invention from simply detecting an undifferentiated object or motion.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The claim language "one or more features" is not facially restrictive. A plaintiff may argue that any data point derived from the image that correlates with a vehicle's presence, such as its general size or shape, constitutes a "feature" ('848 Patent, col. 10:40-45).
      • Evidence for a Narrower Interpretation: The specification provides specific examples of features, such as "the number plate, the color, the make and the model of a vehicle" ('848 Patent, col. 2:57-59). A defendant may argue that the term should be limited to these more specific, identifiable characteristics, rather than encompassing a simple detection of an obstruction.

  • The Term: "segmentation of the respective images into vehicle and non-vehicle objects" ('848 Patent, col. 13:5-8).

    • Context and Importance: This term defines a specific required image processing step. The infringement question will hinge on whether the accused technology performs this particular type of "segmentation" or uses a different, non-infringing algorithm.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The patent does not provide a formal definition of "segmentation." A plaintiff could argue that any processing that computationally distinguishes the pixels corresponding to a vehicle from the pixels corresponding to the empty parking space satisfies this limitation.
      • Evidence for a Narrower Interpretation: The patent’s process flow diagram shows "segment the images to separate vehicle from non-vehicle objects" as a distinct step (ʼ848 Patent, Fig. 2, element 203). A defendant might argue this implies a specific computer vision process that delineates object boundaries, which is more complex than simply detecting a change in the image. The specification also discusses analyzing "non-vehicle objects" separately, which could support the argument that the segmentation must be meaningful ('848 Patent, col. 5:24-30).

VI. Other Allegations

  • Indirect Infringement: The complaint alleges induced infringement, asserting that Defendant provides "user manuals and online instruction materials" that instruct customers on how to use the accused products in an infringing manner, with knowledge and intent that such infringement will occur (Compl. ¶19).
  • Willful Infringement: The complaint alleges willful infringement based on pre-suit knowledge of the ’848 patent. The factual basis for this allegation is that the patent was repeatedly cited by the USPTO against at least two of Defendant’s own patent applications in multiple Office Actions, beginning on October 8, 2014 (Compl. ¶¶13, 20).

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

  • A core issue will be one of claim scope and construction: can the terms "segmentation...into vehicle and non-vehicle objects" and "identifying one or more features...representative of a vehicle's presence" be construed broadly to cover modern, potentially simpler image-based occupancy detection methods, or are they limited by the patent's disclosure to a more complex analysis requiring the identification of specific vehicle characteristics?
  • A key evidentiary question will be one of technical operation: what proof will be offered to show that the accused M4 Smart-Sensor and related systems actually perform the specific image processing steps as recited in the claims? The case will likely require a detailed examination of the accused system’s source code or technical documentation to resolve any dispute over a technical mismatch between its functionality and the claim limitations.
