Case Timeline

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

U.S. Patent No. 7,386,376 - "Vehicle Visual and Non-Visual Data Recording System"

• Patent Identification: U.S. Patent No. 7,386,376, "Vehicle Visual and Non-Visual Data Recording System," issued June 10, 2008.

The Invention Explained

• Problem Addressed: The patent's background section describes that on-scene accident investigations are often time-consuming and inaccurate, relying on witness statements rather than precise data, and that existing vehicle data recorders are limited in the scope of information they capture (Compl. ¶11; ’376 Patent, col. 1:16-25, col. 2:11-17).
• The Patented Solution: The invention is a system that integrates multiple data sources to create a comprehensive record of a vehicle's status before, during, and after an event ('376 Patent, Abstract). It combines traditional vehicle sensors with video from inside and outside the vehicle and, critically, "novel occupant status sensors" and "biometric sensors" to anticipate eccentric conditions and provide a more complete picture for analysis ('376 Patent, col. 2:27-35).
• Technical Importance: The claimed approach sought to provide a more holistic vehicle event analysis by combining and synchronizing visual, vehicular, and biometric data streams, a departure from systems that focused primarily on vehicle performance metrics ('376 Patent, col. 2:48-54).

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 (Compl. ¶18).
• Essential elements of claim 1:
  • An in-vehicle recording system, comprising:
  • a data capture module capturing vehicle data and occupant data, wherein the data capture module captures biometric data;
  • a video capture module recording video data inside and outside the vehicle; and
  • a data recorder in the vehicle, the data recorder recording the vehicle data, the occupant data and the video data and continuously synchronizing the occupant data with the vehicle data.

U.S. Patent No. 9,237,242 - "Roadside and Emergency Assistance System"

• Patent Identification: U.S. Patent No. 9,237,242, "Roadside and Emergency Assistance System," issued January 12, 2016.

The Invention Explained

• Problem Addressed: The patent identifies a weakness in existing vehicle assistance systems that rely solely on cellular networks, which can leave drivers without help if cell service is unavailable (Compl. ¶12; ’242 Patent, col. 1:21-27).
• The Patented Solution: The invention proposes a system with a vehicle unit that has multiple, redundant connectivity options (e.g., cellular, Wi-Fi, vehicle-to-vehicle) to ensure a request for assistance can be transmitted to a server ('242 Patent, Abstract). This server then identifies the vehicle and relays its contact information to an appropriate assistance provider, enabling direct communication ('242 Patent, col. 2:30-41).
• Technical Importance: The system's use of multiple communication protocols provides a failover capability, aiming to create a more robust and reliable emergency assistance network than single-pathway systems ('242 Patent, col. 3:11-16).

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 (Compl. ¶28).
• Essential elements of claim 1:
  • A roadside assistance system comprising:
  • a server receiving an assistance request from a vehicle, the server identifying the vehicle based upon the request and
  • transmitting contact information of the vehicle to an assistance provider, sufficient for the assistance provider to remotely communicate with the vehicle directly.

U.S. Patent No. 9,652,023 - "Power Management System"

• Patent Identification: U.S. Patent No. 9,652,023, "Power Management System," issued May 16, 2017 (Compl. ¶9).
• Technology Synopsis: The patent describes a power management system for an in-vehicle device to conserve battery while remaining responsive. The system’s control unit transitions between ON, OFF, and LOW POWER states based on triggers including vehicle ignition, vehicle running conditions, incoming wireless commands, and environmental stimuli like sound or light changes (’023 Patent, Abstract).
• Asserted Claims: The complaint asserts at least independent claim 1 (Compl. ¶38).
• Accused Features: The complaint accuses the Verizon Connected Car Wi-Fi product. It alleges the product’s control unit has the claimed power states and is commanded to enter the ON state by a power management module in response to the claimed categories of stimuli (Compl. ¶39).

III. The Accused Instrumentality

Product Identification

The complaint names three product families: Verizon Connect Reveal, the Verizon Hum system, and Verizon Connected Car Wi-Fi (Compl. ¶14, ¶27, ¶37).

Functionality and Market Context

• Verizon Connect Reveal: This is described as a fleet-management and monitoring solution. The complaint alleges it includes an in-vehicle system with data and video capture modules that record and synchronize vehicle, occupant, and biometric data (Compl. ¶19). A screenshot provided in the complaint describes a "Driver Drowsiness Detection" feature that can "monitor facial state via sensors" (Compl. p. 6).
• Verizon Hum: This is described as a consumer-focused roadside assistance system. The complaint alleges it operates via a server that receives assistance requests from a vehicle and transmits the vehicle's contact information to a service provider to enable direct communication (Compl. ¶29). A marketing image for the product states it provides "roadside assistance" (Compl. p. 8).
• Verizon Connected Car Wi-Fi: This is described as a vehicle communication system that functions as a Wi-Fi hotspot. The complaint alleges it includes a control unit with multiple power states (OFF, ON, LOW POWER) and a power management module that uses various triggers, including ignition events and environmental stimuli, to manage its power state (Compl. ¶39). A product FAQ screenshot describes the service as providing "in-vehicle internet access" (Compl. p. 10).

IV. Analysis of Infringement Allegations

’376 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central question will be whether the alleged function of monitoring a "facial state via sensors" for drowsiness detection constitutes capturing "biometric data" as required by the claim. The interpretation of this term may determine infringement.
  • Technical Questions: What evidence demonstrates that the accused system "continuously synchroniz[es]" occupant data with vehicle data in the manner contemplated by the patent, versus simply time-stamping separate data streams?

’242 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: The claim is for a "system." The dispute may focus on whether Verizon's architecture, which includes both back-end infrastructure and in-vehicle hardware, constitutes a single "server" under the patent's broad definition of the term (’242 Patent, col. 5:16-20).
  • Technical Questions: The complaint's allegations closely mirror the claim language. A key evidentiary issue will be mapping the specific data flows and component interactions within the Verizon Hum architecture to the functions required by each claim element.

V. Key Claim Terms for Construction

For the ’376 Patent:

• The Term: "biometric data"
• Context and Importance: This term is the lynchpin of the infringement allegation for claim 1. The case may turn on whether analyzing video of a driver's face for signs of drowsiness, as alleged in the complaint, falls within the scope of this term.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent uses the term in the context of logging "indicators of the driver's awareness" (’376 Patent, col. 2:44), which could be argued to encompass drowsiness detection from facial states. The term itself is not explicitly defined or limited in the claims.
  • Evidence for a Narrower Interpretation: The only specific example of a biometric sensor given in the specification is a "heart beat monitor" (’376 Patent, col. 2:43-44). A party could argue this suggests the term is limited to data from dedicated physiological sensors, rather than data derived from video analysis.

For the ’242 Patent:

• The Term: "server"
• Context and Importance: The claim requires a single "server" to perform multiple actions (receiving, identifying, transmitting). Practitioners may focus on this term because Verizon's accused system likely involves a distributed, cloud-based architecture. The viability of the infringement claim depends on whether this architecture can be considered a single "server" as claimed.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification provides an explicit, expansive definition: "the term 'server' is used broadly, as it is understood that a 'server' may include many hardware-independent computers that may even be in different geographic locations" (’242 Patent, col. 5:16-20). This language strongly supports a distributed interpretation.
  • Evidence for a Narrower Interpretation: The detailed description and Figure 1 depict a more structured two-part architecture, comprising a "Service Request Classification and Vehicle Localization (SRCVL) server 22" and a "Telematics Service Processing ('TSP') server 50" (’242 Patent, col. 2:30-40). A party might argue that this specific disclosed structure implicitly limits the otherwise broad term "server" to an entity or entities performing these distinct, coordinated roles.

VI. Other Allegations

• Indirect Infringement: For all three patents, the complaint alleges induced infringement. The allegations are based on Verizon providing the accused products to customers and end-users with the knowledge and intent that they will use the products in an infringing manner (e.g., Compl. ¶20, ¶30, ¶40). The complaint cites marketing materials describing the infringing features, which may be argued to constitute instructions to end-users (e.g., Compl. p. 6, p. 8, p. 11).
• Willful Infringement: The complaint alleges that Verizon had knowledge of infringement "at least as of the date of this Complaint" and, in the alternative, that it was willfully blind to the infringement (e.g., Compl. ¶21-22, ¶31-32, ¶41-42). This framing appears to ground the willfulness claim primarily in post-suit conduct.

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

1. A core issue will be one of definitional scope: Can the term "biometric data" in the ’376 patent, exemplified by a "heart beat monitor," be construed broadly enough to read on drowsiness detection derived from video analysis of a driver's facial state? Similarly, do the accused products' power-saving modes map onto the specific "OFF", "ON", and "LOW POWER" states and their associated triggers as claimed in the ’023 patent?

2. A second central issue will be one of system architecture and evidentiary proof: For the system claims in the ’242 patent, does Verizon's distributed cloud infrastructure and in-vehicle hardware constitute a single "server" performing the claimed functions, particularly given the patent's own broad definition of the term? The complaint's high-level, language-tracking allegations raise the evidentiary question of whether discovery will reveal a functional match or a material difference in the actual technical operation of the accused systems.
