Case Timeline

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

U.S. Patent No. 8,510,076 - “Sensor apparatus and system,”

The Invention Explained

• Problem Addressed: The patent describes a problem with conventional sensor networks used for area monitoring, which typically rely on two distinct types of modules: simple "sensor modules" that detect events and specialized "control modules" that process data and manage the network. This architecture creates a vulnerability, as the loss or failure of a control module can disable an entire segment of the network (’076 Patent, col. 1:36-57). This design is also inflexible for rapid deployment scenarios where module placement may be random and the area of interest may change over time (’076 Patent, col. 1:58-col. 2:25).
• The Patented Solution: The invention is a "self organising adaptive network" composed of homogenous sensor modules, each capable of operating in either a "sensing mode" or a "controlling mode" (’076 Patent, Abstract). A processor within each module determines which mode to adopt based on factors such as its location relative to other modules or an area of interest, the density of other modules, or its own power level (’076 Patent, col. 2:1-25; col. 3:9-18). This allows the network to dynamically adapt its structure for optimal data gathering and resilience, for example by having one module take over as a controller if the original one fails (’076 Patent, col. 3:15-18). The relationship between sensing modules (2a-d) and a module operating in a controlling mode (2e) is illustrated in Figure 4 of the patent.
• Technical Importance: The claimed solution provides a more robust and flexible sensor network that can self-organize after deployment and adapt to changing conditions without relying on predefined, vulnerable control nodes (’076 Patent, col. 3:28-34).

Key Claims at a Glance

• The complaint asserts infringement of "one or more claims" and the "Exemplary '076 Patent Claims" identified in an unprovided exhibit, but does not specify claim numbers in the main body of the complaint (Compl. ¶11). The first independent claim is Claim 1.
• Independent Claim 1:
  • A sensor module for use in a sensor network,
  • comprising at least one sensor, a locator for determining the location of the at least one sensor, a transceiver for communicating with other sensor modules and/or a base station,
  • and a processor wherein the processor is adapted, in use, to communicate with other sensor modules and to determine whether the sensor module should operate in a sensing mode or a controlling mode within the network.
• The complaint does not explicitly reserve the right to assert dependent claims but refers generally to "one or more claims" of the patent (Compl. ¶11).

III. The Accused Instrumentality

Product Identification

The complaint does not name any specific accused products in its text. It refers to the accused instrumentalities as the "Exemplary Defendant Products" which are identified in claim charts attached as Exhibit 2 (Compl. ¶11). This exhibit was not provided with the complaint.

Functionality and Market Context

The complaint does not describe the specific technical functionality of any accused Asustek product. The infringement allegations are made by incorporating the analysis contained within the unprovided Exhibit 2 (Compl. ¶¶16-17). No allegations regarding the products' commercial importance are made in the provided document. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint does not contain narrative infringement allegations or claim charts within its main body. Instead, it alleges that infringement is detailed in charts included as Exhibit 2, which was not provided (Compl. ¶¶16-17). The complaint alleges that the "Exemplary Defendant Products" practice the technology of the '076 Patent and satisfy all elements of the asserted claims (Compl. ¶16). Without the referenced exhibit, a detailed element-by-element analysis based on the complaint is not possible.

Identified Points of Contention

Based on the patent’s claims and the general nature of the dispute, several points of contention may arise once the technical details of the accused products are known.

• Scope Questions: A central question may concern the scope of the term "sensor module." The patent describes rugged, deployable devices for battlefield or disaster monitoring (’076 Patent, col. 1:10-14; col. 8:1-18). If the accused products are consumer electronics (e.g., mesh Wi-Fi routers, smart home devices), a dispute may arise over whether such products fall within the scope of the claimed invention.
• Technical Questions: The core technical question will likely be whether the processors in the accused products perform the specific function of "determin[ing] whether the sensor module should operate in a sensing mode or a controlling mode" as required by the claim (’076 Patent, col. 8:30-32). The court may need to consider what evidence shows that the accused devices dynamically and autonomously switch between two distinct operational modes corresponding to the patent's "sensing" and "controlling" modes, rather than performing more general network management tasks.

V. Key Claim Terms for Construction

The Term: "determine whether the sensor module should operate in a sensing mode or a controlling mode"

• Context and Importance: This functional language is the central limitation of independent claim 1 and captures the core of the purported invention. Practitioners may focus on this term because the entire infringement case will likely depend on whether the processors in the accused products perform this specific, two-part dynamic decision-making process.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification suggests the "determination" can be based on a wide variety of factors, including "the location of the module," the "density of sensor modules," or the "environment," which may support an interpretation covering any algorithmic role-switching in a network (’076 Patent, col. 2:1-25).
  • Evidence for a Narrower Interpretation: The specification also provides more specific examples, such as a module switching to control mode when the current controller "runs out of power" or is "damaged or destroyed" (’076 Patent, col. 3:12-18). This could support a narrower construction requiring the "determination" to be a reaction to a specific failure or power-depletion event.

The Term: "controlling mode"

• Context and Importance: The definition of this term is critical, as infringement requires the accused products to operate in a mode that meets its requirements, distinct from a "sensing mode." The dispute will center on what functions a module must perform to be considered in a "controlling mode."
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent states that in a controlling mode, the processor "receives information relating to events from the sensor modules, possibly processes the information, and passes anything of interest back to a base station" (’076 Patent, col. 2:60-64). This language could support a broad reading where merely relaying or aggregating data from other nodes constitutes a "controlling mode."
  • Evidence for a Narrower Interpretation: The patent also describes the controlling module as one that "controls and processes the data from sensor modules in its vicinity" and upon whose operation "that part of the network is entirely dependent" (’076 Patent, col. 1:46-51). This could support a narrower definition requiring a module to assume a more comprehensive command and data-processing role, rather than simply acting as a data forwarder.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials" that instruct end users on how to use the accused products in an infringing manner (Compl. ¶14). The complaint notes that these materials are referenced in the unprovided Exhibit 2 (Compl. ¶14).

Willful Infringement

The complaint does not allege pre-suit knowledge of the '076 Patent. Willfulness allegations are premised on post-suit conduct, asserting that the filing of the complaint provides "actual knowledge" and that any subsequent infringement is therefore willful and supports a claim for induced infringement (Compl. ¶¶13, 15).

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

• A core issue will be one of functional correspondence: do the accused Asustek products, once identified, contain a processor that performs the specific, dynamic function of "determin[ing]" whether to operate in a "sensing mode" versus a distinct "controlling mode," as claimed in the patent? Or is their network functionality, such as data routing or load balancing, fundamentally different from the adaptive role-switching architecture described?
• A key evidentiary question will be one of technical proof: since the complaint itself provides no technical details about the accused products, the case will depend on discovery to establish how these products actually operate. The central dispute will be whether Plaintiff can map the products' real-world functionality onto the specific limitations of the patent claims.
• The case may also turn on a definitional question: how will the court construe the term "controlling mode"? The outcome could depend on whether the term is interpreted broadly to cover any data aggregation or relay function common in modern networked devices, or more narrowly to require the specific command-and-control and data processing functions described in the patent's preferred embodiments.
