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

U.S. Patent No. 9,510,320 - “Machine for Providing a Dynamic Database of Geographic Location Information for a Plurality of Wireless Devices and Process for Making Same”

Patent Identification

U.S. Patent No. 9510320, "Machine for Providing a Dynamic Database of Geographic Location Information for a Plurality of Wireless Devices and Process for Making Same," issued November 29, 2016.

The Invention Explained

• Problem Addressed: The patent describes the problem of managing wireless network performance, noting that conventional systems often struggle to locate wireless devices accurately, which is necessary to diagnose and correct issues like poor signal quality or network overload, particularly in dense urban or rural environments (’320 Patent, col. 2:54-63).
• The Patented Solution: The invention proposes a "network tuning system" that routinely locates wireless devices, stores their location and performance data in a dynamic database, and uses this information to make "load adjustments" to prevent network overload (’320 Patent, Abstract). The system architecture involves computers that communicate with radio transceivers, compare actual performance data against expected data for a given location, and determine "suggested corrective action" to optimize the network (’320 Patent, col. 129:1-27).
• Technical Importance: This approach allows for proactive, automated network optimization based on the real-time geographic distribution and performance of devices, rather than relying on reactive, manual field analysis by engineers (’320 Patent, col. 37:1-13).

Key Claims at a Glance

• The complaint asserts claims 1-6 (Compl. ¶8). Independent claim 1 is a system claim with the following essential elements:
  • A system including at least one radio-frequency transceiver and an associated antenna.
  • A first computer coupled to the transceiver for communication with at least one mobile wireless device.
  • A second computer coupled to the transceiver to locate the device and generate an indication of its location.
  • The first computer is configured to receive and store performance data of the connection along with the location indication.
  • The first computer references the performance data against expected performance data to determine a "suggested corrective action."
  • The first computer stores updated performance and location data for the device while it is communicating with the transceiver.
  • A second computer communicates with the first computer, which provides an access flag within its memory.
  • The first computer provides access to the location indication to the second computer if the "no access flag" is set.

U.S. Patent No. 8,977,284 - “Machine for Providing a Dynamic Database of Geographic Location Information for a Plurality of Wireless Devices and Process for Making Same”

Patent Identification

U.S. Patent No. 8977284, "Machine for Providing a Dynamic Database of Geographic Location Information for a Plurality of Wireless Devices and Process for Making Same," issued March 10, 2015.

The Invention Explained

• Problem Addressed: As a parent to the ’320 patent, the ’284 patent addresses the same fundamental problem: the need for reliable wireless device location data to effectively manage and tune complex wireless networks (’284 Patent, col. 2:15-22).
• The Patented Solution: The patent describes a machine and process for network tuning that involves locating devices, forecasting their performance, storing the data, and generating corrective actions based on an "error code." (’284 Patent, col. 126:20-50). The solution is presented as a method and a machine for systematically gathering location-specific performance data and using it to improve communication quality (’284 Patent, col. 126:43-50).
• Technical Importance: The invention provides a framework for automating the diagnosis and resolution of wireless network issues by linking performance metrics directly to the geographic location of end-user devices (’284 Patent, col. 37:24-38).

Key Claims at a Glance

• The complaint asserts claims 1 and 4 (Compl. ¶13).
• Independent claim 1 is a method claim with the following essential elements:
  • A wireless network with at least two wireless devices.
  • A first computer programmed to locate at least one device, forecast its performance, and routinely store performance data and location in memory.
  • A radio tower adapted to communicate with the device.
  • The first computer receives performance data and suggests corrective actions based on at least one error code.
  • The operation of the radio tower and device is further programmed to receive the error code and selectively suggest a corrective action to improve communication.
• Independent claim 4 is a system claim directed to a "machine and process for tuning a wireless network," with elements including at least two wireless devices, a first computer, at least two radio towers, a second computer, and a "no access flag" feature for user privacy.

III. The Accused Instrumentality

Product Identification

The complaint accuses a suite of Alcatel-Lucent Enterprise products and services, including its End-to-End 4G LTE Solution, 7750 Service Router Mobile Gateway, 9471 Wireless Mobility Manager, 5780 Dynamic Services Controller (DSC), 5620 Service Aware Manager (SAM), Wireless Network Guardian 9900 (WNG), Intelligent Traffic Management (ITM), IP Multimedia Subsystems (IMS) 9.3, Subscriber Data Manager (SDM), Network Performance Optimizer (NPO), and related network components (Compl. ¶¶8, 13).

Functionality and Market Context

The complaint alleges that these products and services are used to create and operate wireless networks (Compl. ¶8). The core accused functionality is the use of "identified locations of wireless devices to perform adjustments" to the network (Compl. ¶¶8, 13). The complaint does not provide specific technical details on how the accused products operate but positions them as foundational components for modern wireless network infrastructure sold and offered for sale in the United States (Compl. ¶¶2, 8, 13). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint does not provide sufficient detail for a full claim-chart analysis. It offers a high-level, conclusory theory of infringement without mapping specific features of the accused products to the elements of the asserted claims.

The narrative infringement theory is that the Defendant's collection of wireless network components and software, when operating together, create a system that performs the patented methods. Specifically, the complaint alleges that the accused instrumentalities infringe by using the identified geographic locations of wireless devices to make adjustments to the network, which Plaintiff contends falls within the scope of the asserted claims of the ’320 and ’284 patents (Compl. ¶¶8, 13).

• Identified Points of Contention:
  • Scope Questions: The claims of both patents recite distinct "first computer" and "second computer" elements. A central issue may be whether the distributed, software-defined architecture of the accused products contains components that can be separately identified as the claimed "computers." The court will have to determine if these terms require physically separate hardware or if logically distinct software modules operating on shared infrastructure can satisfy the limitation.
  • Technical Questions: The complaint alleges that the accused system performs "adjustments" based on location, but the claims require more specific functions. For the ’320 Patent, what evidence shows the system determines a "suggested corrective action" by comparing "performance data" to "expected performance data" as required by claim 1? For the ’284 Patent, what evidence shows the system "forecasts performance" and generates an "error code" to trigger corrective actions as recited in claim 1? The complaint does not provide this level of technical detail.

V. Key Claim Terms for Construction

The Term: "computer" (e.g., "first computer," "second computer")

• Context and Importance: This term is critical because the claims require separate "first" and "second" computers that perform distinct functions. Defendant's accused system is a suite of integrated products, and the infringement analysis will depend on whether different software modules or hardware components within this suite can be mapped to these separate claim elements. Practitioners may focus on this term because its construction could determine whether a distributed network architecture can meet the elements of a claim drafted with more discrete components in mind.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification suggests that components may be co-located, stating that "ACTUAL COMPONENTS MAY PHYSICALLY RESIDE WITHIN THE SAME HARDWARE" (’284 Patent, Fig. 9). This may support an argument that "computer" refers to a logical function rather than a separate physical device.
  • Evidence for a Narrower Interpretation: The claims consistently distinguish between a "first computer" and a "second computer," implying they are distinct entities. The patent figures also depict system components as separate blocks (e.g., ‘User Location Database Manager’ 904 and ‘BSC’ 118-A in Fig. 12), which may support an argument that the term requires at least logical, if not physical, separation.

The Term: "locating at least said wireless device"

• Context and Importance: The definition of "locating" is central to the scope of the invention. The infringement question may turn on the required precision of the location information (e.g., specific coordinates vs. a general cell sector) and the method used to obtain it.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification discloses a "hierarchy of process for query" and multiple location methods, including triangulation and signal strength, which vary in precision (’284 Patent, col. 18:40-50, Fig. 20). This could support a broad construction that covers any means of determining the general whereabouts of a device.
  • Evidence for a Narrower Interpretation: The specification repeatedly refers to computing specific "latitude/longitude" data (’284 Patent, col. 21:55-65). A party could argue that "locating" requires the generation of specific geographic coordinates rather than merely identifying the cell tower sector a device is in.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement, stating that Defendant "actively encouraged or instructed others (e.g., its customers)" on how to use the accused products in an infringing manner (Compl. ¶¶9, 14). This allegation appears to be based on the act of selling the network components to wireless carriers who then operate the infringing systems.

Willful Infringement

The complaint alleges that Defendant had knowledge of the asserted patents and their underlying technology. This allegation is based on the citation of a related published patent application against Defendant's own patent application in May 2013, as well as notice from the filing of the complaint itself (Compl. ¶¶9, 14). Plaintiff requests that the case be declared "exceptional" to recover attorneys' fees, which is consistent with an allegation of willful infringement (Compl. p. 7, ¶ iv).

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

• A key evidentiary question will be one of technical proof: given the conclusory nature of the complaint, the case will depend on what discovery reveals about the actual operation of the accused Alcatel-Lucent systems. Can Plaintiff produce evidence that these systems perform the specific, granular steps recited in the claims, such as "forecasting performance" or comparing actual data to "expected performance data" to generate "corrective actions"?
• A core issue will be one of architectural interpretation: can the claim terms "first computer" and "second computer," which imply distinct functional units, be construed to read on the components of a modern, highly integrated, and distributed wireless network architecture? The outcome of this claim construction dispute will be critical to the infringement analysis.
• A third question will revolve around damages and willfulness: assuming infringement is found, the allegation of pre-suit knowledge based on a citation in a separate patent prosecution could significantly impact the potential for enhanced damages. The court will need to assess whether knowledge of a related application constitutes the requisite knowledge and intent for willful infringement of the subsequently issued patents.
