U.S. Patent No. 11,307,048 - "Method and System for Providing Travel Time Information"

• Patent Identification: U.S. Patent No. 11,307,048, "Method and System for Providing Travel Time Information," issued April 19, 2022 Compl. ¶26

The Invention Explained

• Problem Addressed: The complaint describes the technological landscape prior to the invention as a choice between two suboptimal navigation solutions: (1) dedicated in-vehicle systems, which were expensive, difficult to upgrade, and generated unreliable traffic data due to their low numbers; and (2) cell phone-based systems, which were more flexible and had more robust data but featured a poor user interface for driving and could not reliably distinguish vehicle traffic from pedestrian movement Compl. ¶¶6-9
• The Patented Solution: The invention proposes a hybrid system that combines the advantages of both approaches Compl. ¶10 It uses a connected cell phone to perform the core navigation functions-determining location, receiving traffic data, and calculating routes-but then transmits this information to the vehicle for presentation on the vehicle's integrated, driver-friendly display Compl. ¶10 The patent describes this as a system for providing route and navigation information to a traveler by locating a mobile communication facility (e.g., a cell phone) and using it to access and display route information '048 Patent, col. 1:55-64
• Technical Importance: This architecture allows automakers to provide sophisticated, easily upgradable navigation features that leverage robust, crowd-sourced traffic data, without incorporating expensive, dedicated navigation hardware into the vehicle itself Compl. ¶11

Key Claims at a Glance

• The complaint alleges infringement of at least independent claim 1 of the '048 Patent Compl. ¶¶31-32
• Independent Claim 1 of the '048 Patent requires:
  • An in-vehicle computer system with an in-vehicle data receiver.
  • The receiver is part of a vehicle and is configured to receive a roadway map and a route to a destination.
  • The route is based at least in part on an estimated roadway traffic condition.
  • The system includes an in-vehicle computer display configured to display the map and route.
  • The estimated traffic condition is based on data from a plurality of other cell phones, determined by their proximity to a roadway or their calculated speed.
• The complaint's reference to "one or more claims" suggests it may assert additional claims, including dependent claims, at a later stage Compl. ¶31

U.S. Patent No. 11,874,131 - "Method and System for Providing Travel Time Information"

• Patent Identification: U.S. Patent No. 11874131, "Method and System for Providing Travel Time Information," issued January 16, 2024 Compl. ¶28

The Invention Explained

• Problem Addressed: As a continuation of the same patent family, the '131 Patent addresses the same technical problems as the '048 Patent: the respective disadvantages of fully built-in versus fully cell phone-based navigation systems Compl. ¶¶6-10
• The Patented Solution: The '131 Patent also claims a hybrid system where a cell phone's capabilities are leveraged for display on a vehicle's screen Compl. ¶10 This patent's claims focus more on the active role of the in-vehicle computer in communicating with the cell phone to initiate data transmission to a remote server for route calculation '131 Patent, cl. 1
• Technical Importance: The technical importance is identical to that of the '048 patent, as it enables advanced, upgradable, and data-rich navigation experiences in vehicles without requiring expensive dedicated hardware Compl. ¶11

Key Claims at a Glance

• The complaint alleges infringement of at least independent claim 1 of the '131 Patent Compl. ¶¶43-44
• Independent Claim 1 of the '131 Patent requires:
  • A display and a computer mounted to a vehicle.
  • The computer is configured to receive user input for a destination.
  • The computer is configured to communicate with a separate cell phone.
  • The computer is configured to cause the cell phone to transmit its self-determined location and the destination to a networked computer facility.
  • This causes the cell phone to receive map data (including route and traffic conditions) from the networked facility.
  • The traffic conditions are based on location signals from other cell phones.
  • The computer then causes the map data received by the phone to be displayed on the vehicle's display.
• The complaint's phrasing suggests the potential assertion of other claims Compl. ¶43

III. The Accused Instrumentality

Product Identification

• The accused instrumentalities are Hyundai vehicles equipped with Apple CarPlay and/or Android Auto functionality (the "Accused Vehicles") Compl. ¶16 The complaint provides a non-exhaustive list of models, including the Accent, Elantra, Ioniq, Palisade, Santa Fe, Sonata, and Tucson, among others Compl. ¶16

Functionality and Market Context

• The accused functionality allows a user's cell phone to connect to the vehicle's infotainment system, which then reformats and displays the phone's user interface on the vehicle's screen and integrates with its controls Compl. ¶12 This enables drivers to use navigation applications like Apple Maps, Google Maps, or Waze, which run on the phone, via the vehicle's built-in display Compl. ¶37 The complaint includes a depiction of an infotainment system displaying the Apple CarPlay interface to illustrate this functionality Compl. p. 5 A second screenshot shows the corresponding Android Auto interface Compl. p. 5
• The complaint alleges that these features are "massively successful" and a key driver of consumer demand for new vehicles, citing a report that 79% of U.S. buyers would only purchase a car that supported CarPlay Compl. ¶13

Identified Points of Contention

• Scope Questions: A central dispute may arise over the meaning of "in-vehicle computer system" and the scope of its claimed functions. For the '131 Patent, a key question will be whether the vehicle's computer, which facilitates user input to a phone app, can be said to "cause said cell phone to transmit" data, or if it merely acts as a passive interface for the phone's own software.
• Technical Questions: The infringement theory relies on the operation of third-party systems (Apple's and Google's servers and apps). An evidentiary question will be what proof the plaintiff can provide that these remote "networked computer facilities" actually estimate traffic conditions using location data from a "plurality of other cell phones" in the manner required by the claims.

V. Key Claim Terms for Construction

Term 1: "in-vehicle computer system" ('048 Patent) / "computer mounted to said vehicle" ('131 Patent)

• The Term: "in-vehicle computer system" / "computer mounted to said vehicle"
• Context and Importance: The definition of the vehicle's "computer" is critical. The dispute will likely focus on whether this term requires a computer with substantive, standalone navigation-processing capabilities, or if it can read on an infotainment system that primarily functions as a display and input/output relay for a connected smartphone.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claims do not specify a minimum level of processing power. A plaintiff may argue that any in-vehicle device with a processor that performs the claimed functions (e.g., receiving data from a phone and rendering it on a display) meets the definition. The patent specification contemplates various configurations, including a simple "in-vehicle communication facility" '048 Patent, col. 3:25-29
  • Evidence for a Narrower Interpretation: A defendant may argue that the invention, as distinguished from prior art cell-phone-only systems in the patent's background, requires the "in-vehicle computer system" to be more than a "dumb terminal." The patent describes embodiments where the system actively provides route, traffic, and navigation information, which may suggest a more computationally robust role is required '048 Patent, col. 1:55-64

Term 2: "cause said cell phone to transmit" ('131 Patent)

• The Term: "cause said cell phone to transmit"
• Context and Importance: This term in claim 1 of the '131 patent is pivotal for determining infringement. Practitioners may focus on this term because the infringement question turns on whether the vehicle's computer is the legal "cause" of the phone's action, or if it is merely a passive conduit for user commands that are acted upon by the phone's own operating system.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: A plaintiff may argue that by providing the interface and the command protocol (e.g., via the CarPlay API) that initiates the entire process, the vehicle's computer is the direct and necessary cause of the phone's subsequent transmission. Without the vehicle computer's action, the phone's transmission for navigation purposes would not occur in this context.
  • Evidence for a Narrower Interpretation: A defendant may argue that the vehicle's computer only relays user input signals to the phone. The phone's OS and the navigation app itself are the software agents that interpret this input and independently decide to initiate a transmission. From this perspective, the user, not the vehicle's computer, is the ultimate "cause."

VI. Other Allegations

• Indirect Infringement: The complaint alleges that Hyundai induces infringement by both its dealerships and its end-user customers (Compl. ¶36; Compl. ¶37). The alleged inducement is based on Hyundai supplying the Accused Vehicles and actively encouraging and instructing customers on how to use the infringing Apple CarPlay and Android Auto features for navigation through marketing materials, instructional YouTube videos, and software updates Compl. ¶38 Compl. ¶50
• Willful Infringement: The willfulness allegation is based on Hyundai's alleged continued infringement after receiving a patent infringement notice letter from the plaintiff on March 25, 2024 Compl. ¶33 Compl. ¶40 Compl. ¶45 Compl. ¶52

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

• A core issue will be one of causation and claim scope: For the '131 patent in particular, can the term "cause," in the context of a vehicle computer interacting with a smartphone, be construed to cover a system where the vehicle primarily provides the user interface for an application running on the phone? The court's interpretation of this active verb will be critical to the infringement analysis.
• A second central question will concern divided infringement: The claimed system involves coordinated actions between the vehicle (sold by Hyundai), the user's smartphone, and a remote server (operated by Apple or Google). A key legal battle will likely focus on whether Hyundai can be held liable for directly infringing the entire claim when it does not control all components of the system, or if the case will depend entirely on the plaintiff's ability to prove induced infringement.
• An evidentiary challenge for the plaintiff will be one of technical proof: Can the plaintiff secure and present admissible evidence demonstrating the precise inner workings of the accused third-party navigation services (e.g., Google Maps), specifically proving that they estimate traffic by collecting and analyzing location data from a "plurality of other cell phones" as required by the claims?
