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

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

• Patent Identification: U.S. Patent No. 8,510,076, "Sensor apparatus and system," issued August 13, 2013.

The Invention Explained

• Problem Addressed: The patent describes a need for rapidly deployable sensor networks for area monitoring, particularly in military contexts (Compl. ¶9; ’076 Patent, col. 1:10-15). It notes that conventional sensor networks often use distinct types of modules—"sensor modules" for detecting events and "control modules" for processing and transmitting data. This creates a vulnerability, as the loss of a dedicated control module can disable an entire section of the network (’076 Patent, col. 1:39-55).
• The Patented Solution: The invention is a single type of sensor module that contains a processor capable of determining whether the module itself should operate in a "sensing mode" (to detect events) or a "controlling mode" (to receive and process data from other modules) (’076 Patent, col. 1:24-34). This determination can be based on factors like the module's location relative to others, the density of sensors in an area, or its remaining power level, creating a "self organising adaptive network" that is more resilient and flexible (’076 Patent, col. 2:1-19).
• Technical Importance: This design creates a decentralized, ad-hoc sensor network that avoids dependence on fixed, high-value control units, thereby increasing the network's robustness and survivability after random deployment (e.g., via air-drop) (’076 Patent, col. 3:26-44).

Key Claims at a Glance

• The complaint asserts infringement of one or more claims of the ’076 Patent, referring to them as the "Exemplary '076 Patent Claims" (Compl. ¶11). While not specified, the analysis centers on the independent claims, such as 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 adapted 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.

III. The Accused Instrumentality

Product Identification

• The complaint refers to "Exemplary Defendant Products" but does not name them in the body of the complaint (Compl. ¶11). It states these products are identified in charts included as Exhibit 2, which was not provided with the publicly filed complaint (Compl. ¶16).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the functionality or market context of the accused products.

IV. Analysis of Infringement Allegations

The complaint alleges infringement by incorporating by reference claim charts from Exhibit 2, which is not included with the filing (Compl. ¶17). Therefore, a claim chart summary cannot be constructed. The complaint’s narrative allegations are conclusory, stating that the accused products "practice the technology claimed" and "satisfy all elements" of the asserted claims (Compl. ¶16). No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Technical Questions: A primary question will be whether the accused products contain a processor that performs the specific function claimed: determining for itself whether to operate in a "sensing mode" or a "controlling mode." The analysis will require evidence of the accused products' network architecture and the logic governing the behavior of individual nodes.
  • Scope Questions: The infringement analysis may turn on whether the accused products, which may be components of a larger system (e.g., an automotive sensor suite), meet the definition of a "sensor module" as described in the patent. The patent's specification heavily details a standalone, ruggedized, air-deployable physical unit with features like a self-righting base and a telescopic mast (’076 Patent, col. 5:21-6:17), raising the question of whether the claims are limited to such a device.

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 limitation is the core of the invention. The outcome of the case may depend on whether the accused products' operational logic falls within the scope of this term. Practitioners may focus on this term because it defines the "self-organizing" aspect of the claimed network, distinguishing it from centrally managed or static-role networks.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself is broad, requiring only that the processor "determine" its mode. This could be argued to cover any system where a node's function can change, regardless of the specific criteria used for the determination.
  • Evidence for a Narrower Interpretation: The specification defines the two modes distinctly, with "sensing mode" involving monitoring a sensor's output and "controlling mode" involving receiving and processing information from other modules for potential re-transmission (’076 Patent, col. 2:26-35, col. 2:60-64). It also provides specific factors for the "determination," such as comparing module locations, sensor density, or power levels, which could be used to argue for a more limited construction requiring these specific types of analysis (’076 Patent, col. 2:1-19, col. 3:7-17).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement "at least since being served by this Complaint" (Compl. ¶15). The basis for inducement is Defendant's distribution of "product literature and website materials" that allegedly instruct end users on how to use the products in an infringing manner (Compl. ¶14).
• Willful Infringement: The complaint asserts that the service of the complaint and its attached claim charts provides Defendant with "actual knowledge" of infringement (Compl. ¶13). The allegations of continued infringement after this notice form the basis for a claim of post-suit willfulness (Compl. ¶14).

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

1. A central issue will be one of architectural equivalence: Do the accused products feature a decentralized architecture where individual modules autonomously "determine" their own operational mode ("sensing" vs. "controlling") as required by the claim, or do they operate within a different network paradigm, such as one governed by a central controller or pre-assigned roles, that does not map onto the patent's specific "self-organizing" framework?
2. A second key issue will be one of definitional scope: Can the term "sensor module," as used in the claims, be construed to cover the accused products, or is the term implicitly limited by the patent's extensive and detailed description of a specific physical apparatus designed for rugged, remote deployment? The resolution of this question will determine whether the patent can be applied beyond the specific battlefield-surveillance context described in the specification.
