• Venue Allegations: Plaintiff alleges venue is proper in the Eastern District of Texas because Defendant's U.S. subsidiaries maintain a regular and established business presence in the district, and because the foreign parent, Toyota Motor Corporation, is subject to venue in any judicial district under the alien venue rule.
• Core Dispute: Plaintiff alleges that Defendant’s Audio Multimedia system, including its Cloud Navigation features, infringes four patents related to non-linear "artistic" map displays, realistic map rendering that adapts to ambient conditions, and client-server route calculation.
• Technical Context: The technology at issue involves in-vehicle GPS navigation systems, a key competitive feature in the modern automotive industry that blends mapping, real-time data processing, and user interface design.
• Key Procedural History: The complaint alleges that infringement of U.S. Patent No. 6,292,743 has been willful since at least 2012, based on a navigation partner (TomTom) having previously cited the patent in a European patent application, which Plaintiff alleges would have been discovered during Defendant's due diligence. For the other three patents, willfulness is alleged from the date of the complaint.

Case Timeline

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

U.S. Patent No. 10,107,628 - "Method and Apparatus for Navigating on Artistic Maps" (issued October 23, 2018)

The Invention Explained

• Problem Addressed: The patent describes conventional GPS maps used in leisure settings like zoos or parks as "boring" and ineffective because they may not display a point of interest until a user is very close, making it difficult to navigate to a specific location within the venue (ʼ628 Patent, col. 1:39-54).
• The Patented Solution: The invention proposes using a non-linearly scaled "artistic map," such as a stylized zoo map, where landmarks are "exaggeratedly shown" for user convenience. A user selects a point of interest on this artistic map. The system then transforms the coordinates of that selection from the artistic map's coordinate system to a physical point (latitude and longitude) on an underlying, non-displayed geographical map and calculates a navigation route to that physical point (ʼ628 Patent, col. 2:26-42; Fig. 3).
• Technical Importance: This technology aims to merge the user-friendly, visually intuitive nature of stylized maps with the functional precision of traditional GPS coordinate-based navigation (ʼ628 Patent, col. 1:61-66).

Key Claims at a Glance

• The complaint asserts independent claim 1 (Compl. ¶30).
• Essential elements of claim 1 include:
  • Downloading a non-linearly scaled "artistic map" with exaggerated objects to a portable computing device.
  • The artistic map is not used directly for navigation, and the underlying geographical map is not displayed.
  • Receiving a user's selection of an object on the artistic map.
  • Determining coordinates for a point on the selected object.
  • Transforming those coordinates to a physical point (latitude/longitude) in the non-displayed geographical map.
  • Detecting the device's current location and determining a navigational direction to the physical point.
  • Showing the navigational direction on the artistic map.

U.S. Patent No. 8,898,003 - "GPS Map Resembling Ambient Environment" (issued November 25, 2014)

The Invention Explained

• Problem Addressed: The patent addresses the static and "boring" nature of typical 2D GPS map displays, which do not change to reflect the real-world environment, such as the time of day or weather conditions (’994 Patent, col. 1:39-44).
• The Patented Solution: The invention describes a method to make a GPS map more realistic. This is achieved by superimposing images representing objects (e.g., landmarks, buildings) to create a 3D impression and, critically, changing the "color effects" of these images based on input from at least one source about ambient conditions. The patent gives the example of an icon of a vehicle on the map showing its headlights on when the vehicle is supposed to turn them on, creating a map with a "certain level of realism" (’994 Patent, col. 2:4-14, 8:14-16).
• Technical Importance: The invention seeks to enhance the user experience by making the navigation interface more immersive and context-aware, moving beyond a simple abstract representation of roads (’994 Patent, col. 1:40-44).

Key Claims at a Glance

• The complaint asserts independent claim 1 (Compl. ¶46).
• Essential elements of claim 1 include:
  • Displaying a map showing a route on which a GPS receiver is moving.
  • Superimposing images of objects (landmarks, buildings, etc.) onto the map to create a 3D impression, where the perspective changes as the receiver moves but the underlying map does not change "relatively."
  • Changing the images with different color effects based on an input about conditions at the location (e.g., weather, time of day).
  • The map is made to resemble the surrounding location with a "certain level of realism."
  • A specific example of this realism is recited: "an icon of a vehicle in the map shows that headlights are on when the vehicle is supposed to turn on its headlights."

U.S. Patent No. 8,406,994 - "Electronically Generated Realistic-like Map" (issued March 26, 2013)

• Technology Synopsis: This patent, the parent of the ’003 patent, addresses the problem of static 2D GPS maps. The patented solution involves superimposing 3D-like images of objects onto a map and dynamically changing their color effects based on external inputs, such as time of day or weather conditions detected by a sensor (e.g., a rain sensor), to create a more realistic and contextually adaptive navigation display (Compl. ¶62; ’994 Patent, col. 2:2-41).
• Asserted Claims: Independent claim 1 is asserted (Compl. ¶62).
• Accused Features: The complaint accuses Toyota's Audio Multimedia system of displaying a map with superimposed 3D objects whose perspective changes with vehicle movement and whose color effects change based on time of day or weather conditions (Compl. ¶62(i)-(iii)). The complaint provides a screenshot from the accused system's user manual showing a "Weather Map" feature (Compl. p. 29).

U.S. Patent No. 6,292,743 - "Mobile Navigation System" (issued September 18, 2001)

• Technology Synopsis: This patent addresses the limitations of standalone navigation systems that rely on potentially outdated, locally-stored map data. The invention describes a distributed, client-server navigation system where a mobile client wirelessly connects to a server, uploads start and end points, and in return receives an optimal route calculated by the server using real-time information (e.g., traffic). The server formats this route as a "non-proprietary, natural language description," which the client then uses to reconstruct the route on its local mapping database ('743 Patent, Abstract; Compl. ¶78).
• Asserted Claims: Independent claim 1 is asserted (Compl. ¶78).
• Accused Features: Toyota's "Cloud Navigation" is accused of operating as a client-server system. The complaint alleges the in-vehicle unit (client) connects to a server to calculate and download optimal routes using real-time information, and subsequently displays the route (Compl. ¶¶78, 44, 45). A screenshot from the accused system's manual shows a "Cloud navigation" subscription screen, which Plaintiff presents as evidence of the claimed client-server architecture (Compl. p. 44).

III. The Accused Instrumentality

Product Identification

• Toyota's "Audio Multimedia" system, which includes the "Drive Connect" suite of services, such as "Cloud Navigation" and "Intelligent Assistant" (Compl. ¶¶10, 25).

Functionality and Market Context

• The complaint describes the accused system as a "next generation" infotainment platform featuring a large touchscreen, voice activation, and cloud connectivity (Compl. ¶10). Its relevant functionality includes displaying 2D and 3D maps, providing navigation with Google Point-of-Interest search, and receiving over-the-air updates (Compl. p. 11). The system allegedly allows users to select a destination by touching a point on the map, which then displays a route to that point (Compl. p. 14). A screenshot from a user manual shows the "Touch and hold operation," which displays a full route map to a selected point (Compl. p. 14). The system is also alleged to automatically switch between "day or night mode" based on whether the vehicle's headlights are on (Compl. p. 30).
• The system's "Cloud Navigation" is alleged to provide route details, turn-by-turn guidance, alternate routes, and live traffic views by connecting to a server (Compl. p. 42). This connectivity is facilitated by Wi-Fi or a cellular connection (Compl. p. 43).

IV. Analysis of Infringement Allegations

10,107,628 Infringement Allegations

Identified Points of Contention

• Scope Questions: A central question is whether the accused 3D road maps qualify as "artistic maps" under the patent's definition. The patent's specification and figures emphasize highly stylized, non-geographic layouts like a zoo map (ʼ628 Patent, Fig. 1), which raises the question of whether a map that is still fundamentally tied to geographic data, even if rendered in 3D, falls within the claim's scope. The meaning of "non-linearly scaled" and "exaggeratedly shown" will be critical.
• Technical Questions: What evidence supports the allegation that the accused system performs a "transforming" step from an artistic map's coordinate system to a geographical one? An alternative technical explanation could be that the 3D map is merely a graphical layer over a standard geographical map, and selecting a POI simply retrieves its pre-existing geographical coordinates without any "transformation" as claimed.

8,898,003 Infringement Allegations

Identified Points of Contention

• Technical Questions: The complaint's evidence for the final limitation—an "icon of a vehicle in the map shows that headlights are on"—is a setting that changes the entire screen's brightness to a day/night mode. The complaint does not provide evidence of a specific vehicle icon displaying headlights. This raises a significant question of whether the accused functionality matches the specific, narrow language of the claim limitation.
• Scope Questions: The claim recites "the map is not changed relatively while the images being imposed change." The meaning of this phrase is ambiguous and may be a key focus of claim construction. A defendant could argue that any change to the superimposed images is, by definition, a change to the overall map being displayed.

V. Key Claim Terms for Construction

For the ’628 Patent:

• The Term: "artistic map"
• Context and Importance: The entire infringement theory for the '628 patent rests on this definition. Practitioners may focus on this term because the patent's examples (e.g., a zoo map) appear technically distinct from the accused product (a 3D-rendered road map), making its construction determinative.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification describes the map as "non-linearly scaled" where "points of interests are exaggeratedly displayed" (’628 Patent, col. 4:4-6). This language could be argued to encompass any map that deviates from a strict, uniform 2D scale, potentially including 3D renderings with prominent landmarks.
  • Evidence for a Narrower Interpretation: The Background and Detailed Description repeatedly use examples of leisure maps for a "zoo, a resort, or a park" (’628 Patent, col. 5:51-52). The figures exclusively show stylized, non-photorealistic maps (e.g., Fig. 1, Fig. 2). This could support an interpretation limiting the term to maps that are illustrative rather than primarily geographic.

For the ’003 Patent:

• The Term: "an icon of a vehicle in the map shows that headlights are on"
• Context and Importance: This is a highly specific limitation that appears to be a point of factual weakness in the complaint's allegations. Practitioners may focus on this term because the evidence provided (a screen-dimming feature) does not literally show what is claimed, making this a potential dispositive issue.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: A plaintiff might argue this limitation should be read functionally, where any visual cue on the map that is directly tied to the vehicle's headlight status meets the spirit of the claim. The claim's purpose is to add "realism" based on ambient conditions, and a screen dimming at night achieves this.
  • Evidence for a Narrower Interpretation: The plain language is explicit. The specification provides direct support for a literal reading, stating, "In a dark environment, the car icon is shown to have headlights on" (’994 Patent, col. 8:15-16). This suggests the invention is the specific visual change to the car icon itself, not a general change to the screen's theme or brightness.

VI. Other Allegations

• Indirect Infringement: For all asserted patents, the complaint alleges induced infringement. The factual basis for inducement is Defendant's alleged advertising of the accused features and the provision of instructions, user manuals, and online support that direct and encourage customers to use the Audio Multimedia system in a manner that performs the claimed methods (Compl. ¶¶36, 52, 68, 84).
• Willful Infringement: The complaint alleges willful infringement for all four patents. For the ’628, ’003, and ’994 patents, the allegation is based on knowledge acquired upon the filing and service of the complaint (Compl. ¶¶34, 50, 66). For the older ’743 patent, the complaint alleges pre-suit willfulness since at least 2012, based on the theory that TomTom (a GPS company that partnered with BMW) was aware of the ’743 patent and that Toyota, in its own due diligence, would have discovered the patent (Compl. ¶82).

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

• A core issue will be one of definitional scope: Can the term "artistic map", which is rooted in the patent's context of stylized theme park and zoo maps, be construed broadly enough to read on the 3D-rendered, but still geographically-based, road maps of the accused navigation system?
• A key evidentiary question will be one of functional mismatch: Does the accused system's automatic screen-dimming feature meet the specific claim limitation requiring "an icon of a vehicle in the map [to show] that headlights are on," or is there a fundamental disconnect between the precise language of the patent claim and the functionality of the accused product?
• A central architectural question for the client-server patent ('743) will be whether Toyota's Cloud Navigation operates by transmitting a "non-proprietary, natural language description" for local reconstruction as claimed, or if it uses a more modern, integrated approach where the client primarily displays data and instructions processed and formatted by the server.
