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 in conventional deployed sensor networks where there are two distinct types of modules: "sensor modules which detect events and control modules which receive data from the sensor modules." ('076 Patent, col. 2:39-42). This architecture creates a vulnerability, as the network segment is "entirely dependent on the operation of the control module," and if it is "located and disabled then that part of the network is disabled." ('076 Patent, col. 2:48-52).
• The Patented Solution: The invention is a single, versatile sensor module that is capable of acting as either a sensor or a controller. Each module contains a processor that communicates with other modules in the network and "determines whether the sensor module should operate in a sensing mode or a controlling mode within the network." ('076 Patent, col. 1:29-34). This allows the network to be "self organising" and "adaptive," as roles can be reassigned based on changing conditions, such as a module being damaged or running low on power, thereby increasing network resilience. ('076 Patent, Abstract; col. 3:6-18).
• Technical Importance: This approach provides a more robust and flexible sensor network that can dynamically adapt to deployment conditions and operational disruptions without relying on pre-designated, fixed-function control units. ('076 Patent, col. 3:28-33).

Key Claims at a Glance

• The complaint asserts infringement of unspecified "Exemplary '076 Patent Claims" (Compl. ¶11). The patent contains two independent claims, 1 (an apparatus) and 22 (a network). Claim 1 is representative.
• The essential elements of independent Claim 1 are:
  • A sensor module for use in a sensor network
  • 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
  • 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, but refers generally to infringement of "one or more claims of the '076 Patent." (Compl. ¶11).

III. The Accused Instrumentality

Product Identification

The complaint does not identify any accused products by name. It refers to "Exemplary Defendant Products" that are purportedly detailed in claim charts attached as Exhibit 2. (Compl. ¶11, ¶16). This exhibit was not filed with the complaint.

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the accused instrumentality's specific functionality or market position. It alleges that the products "practice the technology claimed by the '076 Patent," but offers no specific facts about their operation. (Compl. ¶16).

IV. Analysis of Infringement Allegations

The complaint references claim charts in an unfiled "Exhibit 2" to support its infringement allegations (Compl. ¶17). As this exhibit is not available, the specific factual basis for infringement is not detailed in the provided documents. The complaint's infringement theory is presented in conclusory terms, alleging that the "Exemplary Defendant Products" satisfy all elements of the asserted claims. (Compl. ¶16). No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Questions: A central dispute may revolve around the meaning of a module that can "determine" its own operational mode. The case may question whether a product that is merely configurable by a user or a central server to operate in different states meets this limitation, or if the patent requires the module to make this decision autonomously based on network conditions.
• Technical Questions: A key factual question will be what evidence shows that the accused products operate in two distinct modes that correspond to the "sensing mode" and "controlling mode" described in the patent. The complaint provides no technical details to suggest how the accused products perform this dual-mode function.

V. Key Claim Terms for Construction

"determine whether the sensor module should operate in a sensing mode or a controlling mode" (Claim 1)

• Context and Importance: This phrase is the central inventive concept of the patent. The outcome of the case may depend on whether the accused products perform this specific "determination" function. Practitioners may focus on this term because its interpretation—as either an autonomous decision by the module or a passive configuration by an external source—will be dispositive for infringement.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent states that the "circumstances affecting whether a sensor module acts in a control mode or a sensor mode may include the location of the module," which could suggest the processor simply reacts to static inputs rather than engaging in a complex, dynamic decision-making process. ('076 Patent, col. 2:1-3).
  • Evidence for a Narrower Interpretation: The specification repeatedly describes a "self organising adaptive network" and states the "processor...determines whether to operate in a control mode or a sensor mode." ('076 Patent, Abstract; col. 2:60-62). This language, particularly "self organising," suggests an autonomous, internal decision-making capability is required, not merely being set to a mode by an outside command.

"controlling mode" (Claim 1)

• Context and Importance: The distinction between a "sensing mode" and a "controlling mode" is fundamental to the claim. Without a clear definition, the scope of infringement is ambiguous. The viability of the infringement allegation depends on showing the accused products have a mode of operation that meets the definition of a "controlling mode."
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent does not provide a single, concise definition, which might allow the term to cover a range of functions beyond simple sensing, such as acting as a data relay. The patent mentions that modules acting as relays can "reduce the power needed for communications." ('076 Patent, col. 6:55-63).
  • Evidence for a Narrower Interpretation: The specification describes a module in a "controlling mode" as one that "receive[s] data from the sensor modules for possible analysis and transmission to a base station" and "controls and processes the data from sensor modules in its vicinity." ('076 Patent, col. 2:40-42, 47-48). This points to a more sophisticated, managerial role that involves data processing and network management, not just passive relaying.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials inducing end users and others to use its products in the customary and intended manner that infringes the '076 Patent." (Compl. ¶14).

Willful Infringement

The willfulness allegation is based on post-suit knowledge. The complaint alleges that "at least since being served by this Complaint," Defendant has had "actual knowledge of infringement" and has "actively, knowingly, and intentionally continued to induce infringement." (Compl. ¶13, ¶15).

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

• A core issue will be one of definitional scope: can the claim limitation requiring a module to "determine" its own operational mode be construed to cover a device that is merely configured by an external user or system, or does it require autonomous, in-network decision-making as suggested by the patent’s description of a "self organising" network?
• A key evidentiary question will be one of functional proof: once the accused products are identified, what evidence will emerge to demonstrate that they actually operate in two distinct "sensing" and "controlling" modes that map onto the functions described in the patent? The complaint’s reliance on a missing exhibit leaves the factual basis for this central allegation entirely undeveloped.
