II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,315,769 - Absolute Acceleration Sensor For Use Within Moving Vehicles
The Invention Explained
- Problem Addressed: The patent’s background section describes the difficulty conventional accelerometers face in distinguishing true vehicle deceleration from the effects of gravity when the vehicle is on an incline, which limits their effectiveness in early-warning anti-collision systems (’769 Patent, col. 1:62-2:42).
- The Patented Solution: The invention claims to solve this by using an "accelerometer-gyroscopic sensor" that can provide data on "absolute lateral acceleration" independent of gravitational forces (’769 Patent, Abstract). This data can be used to control vehicle systems, such as adjusting the suspension of different wheels during turning to improve stability and prevent rollovers (’769 Patent, col. 13:15-22; Fig. 4).
- Technical Importance: The technology aims to enable more reliable and sophisticated advanced driver-assistance systems (ADAS) by providing cleaner sensor data that is not corrupted by road geometry (Compl. ¶18).
Key Claims at a Glance
- The complaint asserts infringement of at least Claim 21 (Compl. ¶23).
- Independent Claim 21 includes the following essential elements:
- A method for controlling the performance characteristics of a vehicle.
- Sensing a lateral acceleration of the vehicle.
- Sending a signal to a plurality of control devices based upon the vehicle's lateral acceleration.
- Adjusting a suspension characteristic of the vehicle based upon the lateral acceleration of the vehicle.
- The complaint does not explicitly reserve the right to assert dependent claims.
U.S. Patent No. 8,437,935 - Absolute Acceleration Sensor For Use Within Moving Vehicles
The Invention Explained
- Problem Addressed: The patent specification notes that motor vehicles remaining in an "idling" state unnecessarily pollute the environment and waste fuel (’935 Patent, col. 3:4-17).
- The Patented Solution: The invention provides a vehicle monitoring system that automatically turns off an idling engine to save fuel and reduce emissions (’935 Patent, Abstract; Compl. ¶39). The system uses a vehicle speed sensor to detect a "stationary status," activates an "idling timer," and checks for other conditions such as the transmission being in "park." Upon expiration of the timer and confirmation of the required conditions, a signal is sent to turn off the engine (’935 Patent, Fig. 11).
- Technical Importance: This technology is foundational to modern automatic engine start-stop systems, which are widely used by manufacturers to meet fuel economy standards and environmental regulations.
Key Claims at a Glance
- The complaint asserts infringement of at least Claim 12 (Compl. ¶44).
- Independent Claim 12 includes the following essential elements:
- A method of automatically turning off an idling engine of a vehicle.
- Sensing a stationary status of the vehicle.
- Activating an idling timer.
- Detecting a transmission park-status of the vehicle.
- Wherein if the vehicle is stationary, the idling timer is activated and configured to send a de-activation signal to turn off the engine once the deactivation time window has expired and the transmission park-status is confirmed.
- The complaint does not explicitly reserve the right to assert dependent claims.
U.S. Patent No. 8,682,558 - Absolute Acceleration Sensor For Use Within Moving Vehicles
- Technology Synopsis: This patent describes a system for monitoring and controlling vehicle performance characteristics (Compl. ¶60, 66). It uses an "accelerometer-gyroscope" to sense the absolute acceleration of the vehicle and sends a signal to a vehicle computer unit, which in turn operates one or more vehicle performance systems based on that acceleration data (’558 Patent, Abstract).
- Asserted Claims: At least Claim 11 (Compl. ¶65).
- Accused Features: The complaint alleges that the Volvo 4-C Active Chassis infringes by using a sensor to detect absolute acceleration and a computer to control performance systems based on that data (Compl. ¶66).

- The complaint alleges that the provision and sale of these features are a "source of revenue and a business focus for Defendant" (Compl. ¶30, 51, 72, 93, 114).
- No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
8,315,769 Patent Infringement Allegations
| Claim Element (from Independent Claim 21) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A method for controlling the performance characteristics of a vehicle, comprising: | The Volvo 4-C Active Chassis provides a method for controlling the performance of a vehicle. | ¶24 | col. 15:21-22 |
| sensing a lateral acceleration of the vehicle; | The system senses the vehicle's lateral acceleration. | ¶24 | col. 13:48-52 |
| sending a signal to a plurality of control devices based upon the vehicle's lateral acceleration; | A signal is sent to control devices based on the lateral acceleration. | ¶24 | col. 14:1-4 |
| and adjusting a suspension characteristic of the vehicle based upon the lateral acceleration of the vehicle. | A suspension characteristic is adjusted based on the lateral acceleration. | ¶24 | col. 13:18-22 |
- Identified Points of Contention:
- Technical Questions: The complaint provides a high-level allegation that mirrors the claim language. A central question will be what evidence demonstrates that the Volvo 4-C Active Chassis specifically performs each of these steps. For example, what evidence shows that a signal based on lateral acceleration is sent to a "plurality of control devices" to adjust a "suspension characteristic"?
- Scope Questions: The infringement theory may depend on the definition of "suspension characteristic." The defense could argue this term is limited to the anti-rollover embodiments described in the specification (e.g., stiffening outer suspension and loosening inner suspension), raising the question of whether the accused system's adjustments fall within that scope.
8,437,935 Patent Infringement Allegations
| Claim Element (from Independent Claim 12) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A method of automatically turning off an idling engine of a vehicle...comprising: | The Volvo Remote Start and Volvo Start/Stop provides a method for automatically turning off an idling engine. | ¶45 | col. 17:11-12 |
| sensing a stationary status of the vehicle; | The system senses a stationary status of the vehicle. | ¶45 | col. 17:30-33 |
| activating an idling timer; | The system activates an idling timer with a deactivation time window. | ¶45 | col. 17:39-44 |
| and detecting a transmission park-status of the vehicle; | The system detects a transmission park-status of the vehicle. | ¶45 | col. 17:59-64 |
| wherein if the vehicle is stationary, the idling timer is activated and is configured to send a de-activation signal to turn off the engine once the deactivation time window has expired and the transmission park-status is confirmed... | If the vehicle is stationary, the idling timer is activated and sends a de-activation signal to turn off the engine after the window expires and the park-status of the vehicle is confirmed. | ¶45 | col. 18:1-6 |
- Identified Points of Contention:
- Technical Questions: The claim requires a specific logical sequence. A key question for the court will be whether the accused Volvo systems operate according to this sequence or use a different, more complex set of conditions (e.g., battery charge, engine temperature, HVAC settings) that may not align with the claimed method.
- Scope Questions: Does the accused system's "deactivation time window" function as the claimed "idling timer"? The defense may argue that its system is event-driven rather than governed by a simple timer, raising a question of claim scope.
V. Key Claim Terms for Construction
- The Term: "suspension characteristic" (’769 Patent, Claim 21)
- Context and Importance: This term's scope is critical for the infringement analysis of the Volvo 4-C Active Chassis. A broad definition could cover any adjustment to the suspension, while a narrow one could limit the claim to the specific anti-rollover functions described in the patent. Practitioners may focus on this term because the complaint does not specify what characteristic is being adjusted.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language itself is open-ended and does not specify the type of characteristic being adjusted (’769 Patent, col. 16:21-22).
- Evidence for a Narrower Interpretation: The specification's detailed description primarily discusses adjusting suspension in the context of anti-rollover systems by "stiffening outside suspension and/or loosening inside suspension of moving vehicles" (’769 Patent, col. 13:18-22).
- The Term: "idling timer" (’935 Patent, Claim 12)
- Context and Importance: The existence and function of an "idling timer" is central to the infringement allegations against the Volvo Remote Start and Start/Stop systems. The defendant may argue its systems do not use a simple "timer" but instead rely on a complex algorithm of vehicle conditions, making the definition of this term dispositive.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim itself does not impose structural limitations on the timer. The specification’s flowchart shows the timer activation as a step following the detection of a stationary vehicle (’935 Patent, Fig. 11, step 1106).
- Evidence for a Narrower Interpretation: The specification repeatedly refers to the timer running for a "pre-programmed period" of time, such as "1, 3, 6 or 9 minutes," suggesting a simple, time-based countdown rather than a multi-conditional logic system (’935 Patent, col. 5:12-18).
VI. Other Allegations
- Indirect Infringement: The complaint alleges both induced and contributory infringement for all five patents. Inducement is based on allegations that Defendant instructs customers on how to use the accused features through its website, brochures, and promotional materials (e.g., Compl. ¶26-28, 47-49). Contributory infringement is based on allegations that the accused features are specially designed for infringing use and have no substantial non-infringing uses (e.g., Compl. ¶29, 50).
- Willful Infringement: Willfulness is alleged for all patents, based on Defendant’s purported knowledge since "at least the filing of the original complaint in this matter" (e.g., Compl. ¶34, 55). The complaint also alleges willful blindness, claiming Defendant has a "policy or practice of not reviewing the patents of others" (e.g., Compl. ¶32, 53).
VII. Analyst’s Conclusion: Key Questions for the Case
- A central issue will be one of technical evidence: can Plaintiff provide sufficient evidence to demonstrate that the actual, specific operations of Volvo's sophisticated control systems map onto the elements of the asserted claims, or will discovery reveal a fundamental mismatch between the high-level allegations and the technology's true functionality?
- The case will also likely turn on claim construction: can broad claim terms such as "suspension characteristic" and "idling timer" be construed to cover the accused functionality, or will they be narrowed by the court to the specific embodiments disclosed in the patents, potentially allowing the accused systems to fall outside their scope?
- A key factual question for willfulness will be establishing a date of knowledge: the repeated references to an "original complaint" suggest that the timing and nature of Defendant's alleged pre-suit notice will be a critical point of dispute for determining intent and potential enhanced damages.
