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"

The Invention Explained

  • Problem Addressed: The patent's background describes the difficulty wireless network engineers face in diagnosing and correcting network problems without knowing the physical location of the devices experiencing issues. Traditional methods of taking "snap shots" of network data are often insufficient to pinpoint the cause of problems like dropped calls or poor performance, which can be highly localized. ('320 Patent, col. 37:12-24).
  • The Patented Solution: The invention proposes a "network tuning system" that continuously locates wireless devices on the network, stores this location data along with performance metrics in a dynamic database, and uses this information to suggest or implement "corrective action" to improve network performance. ('320 Patent, Abstract; col. 6:58 - col. 7:16). This allows the network to proactively adjust to changing conditions based on where users actually are and what quality of service they are receiving.
  • Technical Importance: This approach represents a shift from reactive, manual network tuning to a proactive, data-driven system that uses real-time location intelligence to manage network resources. ('320 Patent, col. 37:32-44).

Key Claims at a Glance

  • The complaint asserts claims 1-6. Independent claim 1 is excerpted below.
  • Claim 1 Elements:
    • A system including at least one radio-frequency transceiver configured for communication with at least one mobile wireless communication device.
    • A first computer programmed to locate the device and generate an indication of its location.
    • The first computer receives and stores performance data of connections between the device and transceiver along with the location indication.
    • The first computer determines at least one suggested corrective action in conformity with differences between performance data and expected performance data.
    • A second computer, responsive to a communication from the first computer, sets an access flag within a memory of the first computer.
    • The first computer provides access to the indication of location to the second computer if the access flag is set, and denies access if the flag is not 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"

The Invention Explained

  • Problem Addressed: As a parent to the '320 patent, the '284 patent addresses the same fundamental problem of optimizing wireless networks without precise, real-time geographic data for the devices using the network. ('284 Patent, col. 2:1-24).
  • The Patented Solution: The patent describes a wireless network with computers programmed to locate devices, monitor performance data, and suggest corrective actions based on that data. ('284 Patent, Abstract). The system is designed to create and maintain a dynamic database of location and performance information to allow network engineers to diagnose and correct faults more efficiently. ('284 Patent, col. 37:25-31).
  • Technical Importance: The invention provided a framework for using a device's location not just for user-facing services (like E911), but as a core input for internal network management and optimization. ('284 Patent, col. 7:10-15).

Key Claims at a Glance

  • The complaint asserts claims 1 and 4. Independent claim 1 is excerpted below.
  • Claim 1 Elements:
    • A wireless network comprising at least two wireless devices, a first computer, and at least two radio towers.
    • The first computer is programmed to perform a diagnostic routine by:
      • locating at least one of the wireless devices on the network;
      • routinely storing performance data and corresponding location for the device in memory;
      • reviewing performance data and, based on an error code, suggesting corrective actions to improve communication with the device.
    • The two radio towers are adapted to generate an error code based upon operation and selectively restrict processing of radio frequency signals from at least one of the devices based on the error code.

U.S. Patent No. 9,642,024 - "Mobile Wireless Communications System and Method with Corrective Action Responsive to Communications Fault Detection"

  • Technology Synopsis: This patent, also in the same family, focuses on a system that detects a communication fault between a mobile device and the network. The system references performance data against expected performance data in conjunction with the device's location to determine and take corrective action to remedy the fault. ('024 Patent, Abstract).
  • Asserted Claims: 1, 6, 11, and 17. (Compl. ¶18).
  • Accused Features: The complaint alleges infringement by Defendant's wireless networks, network components, and related services that use device locations to perform adjustments. (Compl. ¶18).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are a broad range of Defendant's wireless networking products and services. (Compl. ¶¶ 8, 13, 18). This includes, among many others, control systems (e.g., OmniSwitch Model products, OmniAccess Model products), network management systems (e.g., OMNIVISTA 8770 NETWORK MANAGEMENT SYSTEM), and related wireless network components and handsets. (Compl. ¶¶ 8, 13, 18).

Functionality and Market Context

The complaint alleges that these products, when used, form wireless networks that "use identified locations of wireless devices to perform adjustments." (Compl. ¶¶ 8, 13, 18). The extensive list of accused products suggests that Plaintiff's infringement theory targets the core functionality of Defendant's enterprise wireless networking portfolio. (Compl. ¶¶ 4-6, 11-13, 18-21). The complaint does not, however, describe the specific technical mechanisms by which the accused products allegedly locate devices or perform network adjustments.

IV. Analysis of Infringement Allegations

The complaint does not provide element-by-element infringement allegations or reference a claim chart exhibit. Instead, it asserts a general theory that Defendant's suite of wireless networking products, when operating, necessarily practices the patented methods of locating devices and using that location information to perform network adjustments. (Compl. ¶¶ 8, 13, 18). No probative visual evidence provided in complaint.

  • Identified Points of Contention:
    • Evidentiary Questions: The complaint's allegations are stated at a high level. A central point of contention will be factual: what evidence exists that the accused products, in their normal operation, perform the specific steps recited in the asserted claims? For example, what proof shows the systems "routinely store performance data and a corresponding location" and then "suggest[] corrective actions" based on an "error code" as required by claim 1 of the '284 Patent?
    • Scope Questions: The claims of the '320 and '284 patents recite a system comprising multiple distinct components (e.g., a "first computer" and a "second computer" in claim 1 of the '320 patent). A potential issue is whether the various accused products, which may be sold and operated separately, can be combined to meet these structural limitations and, if so, who would be liable for that combined infringement.

V. Key Claim Terms for Construction

  • The Term: "suggested corrective action" ('320 Patent, claim 1) / "suggests corrective actions" ('284 Patent, claim 1)
  • Context and Importance: This term appears in the independent claims of both lead patents and is central to the invention's purpose of tuning the network. The definition of "suggests" will be critical. If it is construed to require a recommendation to a human operator for review and implementation, it may not read on fully automated network management systems. If it is construed more broadly to include automated adjustments implemented by the system itself, the scope of the claim would be significantly wider. Practitioners may focus on this term because the degree of automation in the accused systems will be a key factual issue.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification describes an "automatic correction mode" where the "system would be allowed to make adjustments to the wireless network" without human intervention, which may support a construction where a "suggestion" can be an internal, automated command. ('284 Patent, col. 40:8-12).
    • Evidence for a Narrower Interpretation: The plain meaning of "suggest" implies a recommendation made to an entity capable of accepting or rejecting it, such as a human engineer. The specification also describes embodiments where a "display screen" is used to present information to a user, who can then interact with the system, which may support a narrower construction requiring the possibility of human review. ('284 Patent, Fig. 28; col. 45:53-61).

VI. Other Allegations

  • Indirect Infringement: The complaint alleges inducement, stating that Defendant "has actively encouraged or instructed others (e.g., its customers)... on how to use its products and services" in an infringing manner. (Compl. ¶¶ 9, 14, 19). The complaint does not cite specific user manuals, marketing materials, or other instructional documents.
  • Willful Infringement: The complaint alleges Defendant had knowledge of the asserted patent family prior to the suit. The primary basis for this allegation is that a published application from the patents' family (US 2008/0045234) was cited by the USPTO against one of Defendant’s own patent applications (USSN 13/389,495) in May 2013, years before the '284, '320, and '024 patents issued. (Compl. ¶¶ 9, 17, 20). Post-suit knowledge is also alleged based on service of the complaint. (Compl. ¶9).

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

  • A core issue will be one of evidentiary sufficiency: Given the complaint's high-level allegations, the case will likely depend on whether discovery produces evidence that Defendant's complex networking products, in operation, actually perform the specific, multi-step processes of locating devices, correlating location with performance data, and using that correlated data to implement corrective actions as recited in the claims.
  • A second key question will be one of claim construction: The viability of the infringement claims may turn on whether terms like "suggests corrective actions" are interpreted to cover fully automated network adjustments or if they require a recommendation to be made to a human operator, creating a potential mismatch with the functionality of modern, automated network management systems.
  • Finally, a critical question for damages will be pre-suit knowledge: Plaintiff’s allegation that Defendant was aware of the underlying technology via a citation during the prosecution of its own patent application raises a significant factual dispute over whether any infringement was willful.
