Case Timeline

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

U.S. Patent No. 8,483,941 - "Vehicle Speed Monitor"

The Invention Explained

• Problem Addressed: The patent identifies that speeding is a primary cause of traffic accidents and that conventional enforcement methods, such as police radar, monitor speed at a single point in time (’941 Patent, col. 1:4-15). This suggests a need for a more continuous method of speed monitoring over a stretch of road.
• The Patented Solution: The invention proposes a system where a portable device, described as an "integrated circuit (IC) card," is provided to a vehicle at an entrance to a road, such as a tollway (’941 Patent, col. 2:42-46). This card contains a three-axis accelerometer that measures and records the vehicle's accelerations during its journey (col. 1:19-24). At the road's exit, the card is returned, its data is downloaded, and the vehicle's speed profile is calculated from the acceleration data to determine if a speed limit was violated (col. 2:46-54). Figure 1 illustrates this process with an entrance booth (104) and an exit booth (108).
• Technical Importance: The technology provides a mechanism for monitoring a vehicle’s speed over an entire segment of a journey, rather than at a discrete point, offering a potentially more comprehensive approach to speed limit enforcement.

Key Claims at a Glance

• The complaint asserts at least independent Claim 1 (Compl. ¶24).
• The essential elements of Claim 1 are:
  • An integrated circuit (IC) card comprising:
  • An accelerometer configured to measure instantaneous accelerations along three axes;
  • A nonvolatile memory;
  • A contact or contactless interface; and
  • A processor programmed to:
    • record the measured instantaneous accelerations over time in the nonvolatile memory, and
    • transmit, via the interface, either (1) the recorded accelerations or (2) scalar instantaneous speeds derived from those accelerations.
• The complaint alleges infringement of "one or more claims," preserving the right to assert additional claims (Compl. ¶21).

III. The Accused Instrumentality

Product Identification

• The complaint identifies the "Geotab GO9 device" as the Accused Product (Compl. ¶17).

Functionality and Market Context

• The complaint does not describe the specific functionality or technical operation of the Geotab GO9 device. It is generally known in the market as a vehicle telematics and fleet management device installed in vehicles to collect and transmit data related to location, speed, engine diagnostics, and driver behavior. The complaint alleges this device infringes the ’941 Patent but provides no further detail on its market position or specific features (Compl. ¶17).

IV. Analysis of Infringement Allegations

The complaint alleges that the Accused Product directly infringes at least Claim 1 of the ’941 Patent (Compl. ¶24). It states that an "exemplary claim chart detailing representative infringement of Claim 1" is attached as Exhibit B; however, this exhibit is not included with the complaint document as filed (Compl. ¶24). The body of the complaint does not contain a narrative infringement theory or otherwise map specific features of the Accused Product to the limitations of Claim 1. No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Scope Questions: The patent specification consistently frames the invention around a portable "IC card" that is provided to a driver at a road "entrance" and returned at an "exit" (’941 Patent, Abstract; col. 3:4-29). A primary legal question will be whether the scope of the term "integrated circuit (IC) card" can be construed to read on a semi-permanently installed telematics device, such as the Geotab GO9, which is not typically provided and returned on a per-trip basis.
  • Technical Questions: For the infringement allegation to succeed, the Plaintiff must prove that the Geotab GO9's processor is "programmed to" perform the specific functions of recording and transmitting acceleration or speed data as recited in Claim 1. The complaint's lack of factual allegations on this point raises the evidentiary question of what data the GO9 device actually measures, records, and transmits, and whether its operation aligns with the claimed method.

V. Key Claim Terms for Construction

• The Term: "integrated circuit (IC) card"

  • Context and Importance: The construction of this term appears central to the dispute. If construed narrowly, it may limit the claim scope to portable, temporary-use devices like smart cards used in a tolling context, potentially excluding the accused semi-permanently installed telematics device.
  • Intrinsic Evidence for a Broader Interpretation: The claim language itself does not explicitly limit the form factor or permanence of the "IC card." A party could argue that any self-contained device incorporating an integrated circuit that performs the claimed functions meets this limitation.
  • Intrinsic Evidence for a Narrower Interpretation: The specification repeatedly uses language that suggests a specific, transactional embodiment, describing the device being "provide[d]... to the driver" at an "entrance booth" and received back at an "exit booth" (’941 Patent, col. 3:4-25). The patent also suggests the device may conform to smart card standards such as ISO 7816 (col. 5:23-28), supporting an interpretation tied to a portable card-like form factor.

• The Term: "processor being programmed to record the instantaneous accelerations"

  • Context and Importance: This functional limitation is critical for infringement. Practitioners may focus on this term because the accused device may not record raw "instantaneous accelerations" but instead may process such data to identify and record specific events (e.g., "harsh braking," "rapid acceleration") or calculate other metrics.
  • Intrinsic Evidence for a Broader Interpretation: A party might argue that "record the instantaneous accelerations" does not require storing raw sensor readings indefinitely, and that any recording process that relies on these measurements (even if intermediate) would satisfy the limitation.
  • Intrinsic Evidence for a Narrower Interpretation: The specification describes a system where acceleration data is recorded over time and later downloaded for a separate computer system to analyze (’941 Patent, col. 4:10-16). This could support a narrower construction requiring the device to log the underlying acceleration data itself, rather than just derivative, high-level event data.

VI. Other Allegations

The complaint does not allege indirect infringement or willful infringement.

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

• A core issue will be one of definitional scope: can the term "integrated circuit (IC) card", as described in a patent focused on a temporary, per-trip tollway monitoring system, be construed to cover a modern, semi-permanently installed fleet management telematics device? The outcome of this construction may be dispositive.
• A key evidentiary question will be one of operational equivalence: does the accused Geotab GO9 device, in its actual operation, perform the specific functions of recording and transmitting either raw acceleration data or scalar speeds as required by Claim 1? Given the complaint's lack of technical specifics, discovery into the accused product's architecture and data handling protocols will be necessary to resolve this question.
