II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,925,426 - "Power Management Systems And Devices"
- Issued: April 12, 2011.
The Invention Explained
- Problem Addressed: The patent describes the problem of imprecise and rudimentary management of energy efficiency in vehicles, noting that a driver’s desired speed (e.g., the speed limit) is often not the most power-efficient speed for travel (Compl. ¶¶ 29-30).
- The Patented Solution: The invention proposes a method where a computer system segments a travel route and, for each segment, calculates two distinct speeds: an "optimized speed" that minimizes power consumption and a "probable speed." The system then determines a final "efficient speed" based on a combination of these two values and applies the corresponding power to the vehicle's engine to travel the segment (Compl. ¶¶ 31-32; ’426 Patent, col. 6:4-16).
- Technical Importance: This method provided a technological solution to improve vehicle efficiency and thereby reduce consumer "range anxiety," a significant hurdle to the adoption of electric vehicles (Compl. ¶ 33).
Key Claims at a Glance
- The complaint asserts independent Claim 1 (Compl. ¶ 34).
- Claim 1 requires a method of managing vehicle power consumption by:
- receiving a route;
- segmenting the route into segment destinations;
- for each segment, calculating an optimized speed by minimizing power consumption using inputs such as external environment, operational status, and user commands;
- for each segment, calculating a probable speed;
- for each segment, determining an efficient speed based on said optimized speed and said probable speed; and
- applying the calculated power corresponding to the determined efficient speed to the vehicle engine.
U.S. Patent No. 8,972,161 - "Power Management Systems And Devices"
- Issued: March 3, 2015.
The Invention Explained
- Problem Addressed: The patent is directed to increasing the efficiency of electric vehicles to reduce range anxiety while still allowing the driver to maintain control over the vehicle's operation (Compl. ¶ 39).
- The Patented Solution: The claimed method involves segmenting a route and calculating a plurality of potential energy consumption values based on different variations in a target speed. The system then determines the "efficient speeds" that achieve the "best summation" of these energy values. Crucially, rather than automatically controlling the vehicle, the system then notifies the operator of these efficient speeds, allowing the driver to adjust their driving accordingly (’161 Patent, col. 6:23-45; Compl. ¶ 40).
- Technical Importance: By providing speed recommendations to the driver, the technology aims to increase operator confidence and enjoyment while improving vehicle efficiency without fully removing driver control (Compl. ¶ 40).
Key Claims at a Glance
- The complaint asserts independent Claim 1 (Compl. ¶ 41).
- Claim 1 requires a method of managing a vehicle's power consumption by:
- receiving a route at a computer of the vehicle;
- segmenting the route into a plurality of segment destinations;
- calculating a plurality of energy values consumed to travel the route based on a plurality of variations in a target speed between segment destinations;
- determining a plurality of efficient speeds that achieve a best summation of said energy values; and
- notifying an operator of the vehicle about said efficient speeds to travel between each segment destination.
U.S. Patent No. 10,829,002 - "Vehicle Destination Prediction"
- Issued: November 10, 2020 (Compl. ¶ 42).
Technology Synopsis
This patent addresses range anxiety related to the uncertainty of finding a charging station (Compl. ¶ 45). It discloses a power management device that collects and analyzes vehicle sensor data (including driver-related and telemetry data) along with historical operational data to detect patterns and predict a driver’s destination, such as a necessary charging location along a route (’002 Patent, Abstract; Compl. ¶ 46).
Asserted Claims
The complaint asserts at least Claim 1, an apparatus claim for a power management device (Compl. ¶ 48).
Accused Features
The complaint alleges that Tesla's navigation system predicts when a vehicle has insufficient charge to reach a destination and automatically routes it to a supercharger, a feature alleged to embody the destination prediction technology (Compl. ¶ 24).
U.S. Patent No. 10,850,616 - "Using Vehicle Systems To Generate A Route Database"
- Issued: December 1, 2020 (Compl. ¶ 49).
Technology Synopsis
The patent addresses the problem that individual vehicles have limited information about conditions on future route segments (Compl. ¶ 52). The solution involves an apparatus that collects sensor data from multiple vehicles, associates that data with specific route segments, and uploads it to a remote database. This aggregated data creates a comprehensive, historical picture of route conditions (e.g., traffic) that can be used to provide more efficient routing to other vehicles, thereby reducing range anxiety (’616 Patent, Abstract; Compl. ¶¶ 53-54).
Asserted Claims
The complaint asserts at least Claim 1, an apparatus claim (Compl. ¶ 55).
Accused Features
The complaint accuses Tesla's system of collecting sensor information from its vehicle fleet and uploading it to a remote database to determine congestion at supercharger sites, then using this crowdsourced information to automatically route other vehicles to stations with less congestion (Compl. ¶ 24).
U.S. Patent No. 10,882,399 - "Electric Vehicle Power Management System"
- Issued: January 5, 2021 (Compl. ¶ 56).
Technology Synopsis
The patent is directed to solving the problem of inefficient vehicle travel due to a user having limited information about the vehicle and its environment (Compl. ¶ 59). It discloses a method of electric vehicle operation that involves determining information about the vehicle's external environment, operational status, and user inputs (including voice commands), and then applying a calculated electric power to travel a route segment at a calculated speed (’399 Patent, Abstract; Compl. ¶ 60).
Asserted Claims
The complaint asserts at least Claim 1, a method claim (Compl. ¶ 61).
Accused Features
The complaint alleges that Tesla's system collects and uses data such as forecasted wind speed to more accurately predict energy consumption and manage power, a function alleged to infringe the claimed method (Compl. ¶ 24).
III. The Accused Instrumentality
Product Identification
The accused products are Tesla vehicles, including but not limited to the Model S, Model 3, Model X, and Model Y (collectively, the "Accused Tesla Vehicles") (Compl. ¶ 3). The infringement allegations center on the vehicles' power management and navigation systems.
Functionality and Market Context
The complaint alleges that the Accused Tesla Vehicles contain systems designed to solve "range anxiety" (Compl. ¶ 24). These systems are alleged to collect and use sensor and other data, such as "the route, the initial battery pack temperature, forecasted wind speed and direction," to predict energy consumption. The system is also alleged to predict a user's destination, determine if the vehicle has sufficient charge, and intelligently route the vehicle to supercharger stations. A further accused feature is the system's ability to collect and analyze sensor information from the vehicle fleet, associate it with route segments, and upload it to a remote database to inform routing decisions for other vehicles based on factors like charging station congestion (Compl. ¶ 24). No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
'426 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a computer device receiving a route; | The Tesla system receives a route when a user inputs a destination, such as "navigate to Aspen, Colorado." | ¶24 | col. 5:58-63 |
| said computer device segmenting said route into segment destinations; | The Tesla system inherently segments the route to identify necessary supercharger stops and route portions (e.g., "take me along I-80 through Salt Lake City"). | ¶24 | col. 6:4-6 |
| calculating an optimized speed by minimizing power consumption over said segment destination, wherein information is...received as input... | The Tesla system collects and uses sensor and other data, such as "the route, the initial battery pack temperature, forecasted wind speed and direction," to predict energy consumption, which is the basis for minimizing power use. | ¶24 | col. 4:44-53 |
| calculating a probable speed; | The Tesla system is alleged to predict a user's destination when it determines the vehicle lacks sufficient charge for the entire route, which suggests a calculation of a probable route or speed. | ¶24 | col. 6:9-11 |
| determining an efficient speed based on said optimized speed and said probable speed; | The complaint does not provide sufficient detail for analysis of how the Accused Tesla Vehicles allegedly combine a distinct "optimized speed" and "probable speed" to determine a final "efficient speed." | col. 6:11-13 | |
| applying the calculated power corresponding to said determined efficient speed to the vehicle engine to travel said segment destination. | The complaint alleges that Tesla's use of its patented inventions allows it to overcome range anxiety, implying that the system's calculations result in the application of power to the vehicle to achieve an efficient trip. | ¶24 | col. 6:14-16 |
Identified Points of Contention
- Scope Questions: A central question may be whether Tesla’s integrated navigation and energy management system performs the discrete, sequential calculations required by Claim 1. For example, does the system calculate a distinct "probable speed" that is then mathematically combined with a separately calculated "optimized speed," or does it use a more holistic algorithm where these concepts are implicitly considered but not explicitly calculated as separate variables?
- Technical Questions: The complaint's allegations focus on high-level features like routing to superchargers. A key factual question will be what evidence shows that this routing is based on the specific multi-step speed calculation method claimed in the patent, as opposed to a different logic for energy management.
'161 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| receiving a route at a computer of said vehicle; | The Tesla system receives a route when a user enters a destination into the navigation system. | ¶24 | col. 6:23-25 |
| segmenting said route into a plurality of segment destinations; | The Tesla system segments the route to identify supercharger stops and plan the journey in stages. | ¶24 | col. 6:26-27 |

| determining a plurality of efficient speeds that achieve a best summation of said energy values; | The complaint alleges Tesla's overall solution to range anxiety relies on its patented inventions, which implies a determination of efficient speeds to successfully complete a trip. | ¶24 | col. 6:34-36 |
| notifying an operator of said vehicle about said efficient speeds to travel between each of said segment destinations. | The complaint does not provide sufficient detail for analysis of how the Tesla user interface specifically "notifies" the operator of a plurality of determined efficient speeds for upcoming route segments, as distinct from simply displaying the current vehicle speed. | col. 6:37-40 |
Identified Points of Contention
- Scope Questions: Practitioners may focus on whether the phrase "calculating a plurality of energy values... based on a plurality of variations in a target speed" requires the system to run multiple, discrete simulations. Does Tesla's system perform such a multi-variant calculation, or a single-path optimization?
- Technical Questions: A key question will be what constitutes "notifying an operator" under the claim. Does the vehicle's standard user interface, which displays current speed and navigational guidance, meet this limitation, or does the claim require a more explicit recommendation, such as "To maximize range, travel the next segment at 65 mph"?
V. Key Claim Terms for Construction
For the ’426 Patent
The Term: "probable speed"
- Context and Importance: This term is not a standard term of art and is central to distinguishing the invention from a simple "optimized speed" calculation. The infringement analysis will depend on whether Tesla’s system can be shown to calculate a value that meets the patent's definition of "probable speed." Practitioners may focus on this term because it appears to require a predictive, forward-looking calculation beyond simple energy minimization.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification suggests this speed can be determined based on "historical speeds for similar destinations" (’426 Patent, col. 5:40-42), which could be interpreted broadly to cover any predictive speed based on past data.
- Evidence for a Narrower Interpretation: The specification links the concept to "statistical route analysis logic" and historical trip data for the same route (’426 Patent, col. 7:42-45; FIG. 5), suggesting a narrower meaning tied to specific historical data analysis for that particular segment.
The Term: "efficient speed based on said optimized speed and said probable speed"
- Context and Importance: This limitation requires a specific relationship between three calculated values. Infringement requires not just that the system calculates an efficient speed, but that it does so by combining the other two specifically claimed speed calculations.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language "based on" is often given a broad meaning, suggesting that the optimized and probable speeds need only be inputs into the final calculation, without requiring a specific mathematical formula.
- Evidence for a Narrower Interpretation: The specification describes the "efficient speed output" as being determined by a "combination of the calculated optimized speed and the probable optimized speed after they have been appropriately weighted" (’426 Patent, col. 8:36-40), suggesting a more structured, weighted-average type of calculation is required.
For the ’161 Patent
The Term: "notifying an operator... about said efficient speeds"
- Context and Importance: This is the dispositive output step of the claim. Unlike the ’426 Patent which applies power, this claim requires communicating information to the driver. Whether Tesla's user interface performs this function as claimed will be a critical issue.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification mentions that the system may "provide a suggested fuel-efficient speed to the driver, who in turn will manually adjust his/her speed" (’161 Patent, col. 2:48-51), which might support an argument that any display of a target speed for the driver to follow constitutes "notifying."
- Evidence for a Narrower Interpretation: The claim requires notifying the operator about "efficient speeds to travel between each of said segment destinations," suggesting a forward-looking notification for future segments, not merely a display of the current target speed for the present segment. The specification also describes a user interface showing a "derived efficient speed" alongside the current speed, which could imply the notification must be an explicit, distinct recommendation (’161 Patent, FIG. 8).
VI. Other Allegations
Indirect Infringement
The complaint alleges that Tesla actively induces infringement by providing customers with directions, user manuals, and other communications that explain how the accused functionalities work and instruct users to operate the Accused Tesla Vehicles in a manner that directly infringes the patents (Compl. ¶¶ 67, 77, 87, 97, 107).
Willful Infringement
The complaint alleges willful infringement based on pre-suit knowledge. It states that Plaintiff sent a letter to Tesla on January 28, 2021, which provided actual notice of each of the five Patents-in-Suit and iQar's contention of infringement (Compl. ¶¶ 25, 66, 76, 86, 96, 106).
VII. Analyst’s Conclusion: Key Questions for the Case
This case appears to present several central questions for the court concerning the intersection of established patent claim language and modern, algorithm-driven automotive technology.
- A core issue will be one of algorithmic specificity: do the patents’ claims, which recite discrete computational steps (e.g., calculating a "probable speed" and an "optimized speed" and then combining them), cover the accused Tesla systems, which may use a more integrated, holistic machine-learning approach to determine an efficient travel plan? The dispute may turn on whether Tesla's system can be shown to perform the specific, ordered calculations required by the claims.
- A second key question will be one of evidentiary proof for "crowdsourcing": for the ’616 patent, what evidence will demonstrate that data uploaded from one vehicle is used to create a "historical route information" database that is then used to direct a "plurality of" other, unrelated vehicles, as required by the claims, rather than merely being used for internal analytics or fleet-wide software updates?
- Finally, a critical question for the '161 patent will be one of functional interpretation: does the standard display of a target or cruise control speed on a vehicle's dashboard constitute "notifying an operator... about said efficient speeds to travel between each of said segment destinations," or does the claim require a more explicit, forward-looking recommendation for future segments of a route?
