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,” issued November 29, 2016
The Invention Explained
- Problem Addressed: The patent describes the general problem that accurately determining the location of a wireless device can be difficult due to factors like signal obstruction in urban environments, which complicates network management and the provision of location-based services (’320 Patent, col. 2:58-64).
- The Patented Solution: The invention proposes a "tuning system" that routinely locates wireless devices, collects performance data, and uses this information to make "load adjustments" to prevent network overload (’320 Patent, Abstract). This is achieved through a multi-computer architecture where one computer gathers location and performance data, and a second computer analyzes it to determine and suggest "corrective actions" based on discrepancies between expected and actual performance (’320 Patent, col. 129:1-44).
- Technical Importance: The technology provides a method for proactive and automated wireless network optimization based on the real-time geographic distribution and performance of user devices (’320 Patent, col. 37:1-13).
Key Claims at a Glance
- The complaint asserts infringement of claims 1-6 (Compl. ¶8).
- Independent Claim 1 recites a system comprising:
- At least one radio-frequency transceiver and antenna.
- A first computer, coupled to the transceiver, programmed to locate a mobile wireless device, generate an indication of its location, receive and store performance data, and determine a "suggested corrective action" in response to differences between expected and actual performance data.
- A second computer, in communication with the first, that is responsive to communications, stores updated performance data, and provides or denies access to the location indication based on a "no access flag."
- The complaint’s reference to claims 1-6 suggests it may later rely on the specific features recited in dependent claims 2-6 (Compl. ¶8).
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,” issued March 10, 2015
The Invention Explained
- Problem Addressed: The patent identifies the need for a more reliable and cost-effective method for locating wireless devices than was available with technologies like GPS, which can be unreliable indoors or in dense urban areas (’284 Patent, col. 2:33-48).
- The Patented Solution: The invention describes a wireless network with at least two radio towers and associated computers that locate wireless devices, store their performance data and location, and perform diagnostic routines based on an "error code" to suggest "corrective action" to improve communication (’284 Patent, Abstract; col. 126:20-53). The system is designed to create, store, and act upon detailed "case files" that correlate device location with various network performance metrics, as shown in the interworking system diagram of Figure 28 (’284 Patent, Fig. 28; col. 38:22-30).
- Technical Importance: This system allows network operators to move beyond simple signal strength measurements and perform sophisticated, location-aware diagnostics to maintain quality of service (’284 Patent, col. 37:1-13).
Key Claims at a Glance

Identified Points of Contention
- Architectural Scope: A primary question will be whether Motorola's distributed system of various software (e.g., RFMS, SOLE) and hardware (e.g., servers, switches) components constitutes the "first computer" and "second computer" recited in the claims. The defense may argue that the claims require more discrete components than the collection of products accused.
- Functional Questions: The complaint makes a general allegation that the accused system performs "adjustments." This raises the question of whether evidence will show that these adjustments meet the specific claim requirements, such as determining a "suggested corrective action" based on a difference between "expected" and "actual" performance data (’320 Patent) or acting on a specific "error code" (’284 Patent).
V. Key Claim Terms for Construction
The Term: "computer" ("first computer", "second computer")
- Context and Importance: The claims are structured around a "first computer" and a "second computer." The complaint accuses a broad suite of hardware and software. The construction of "computer" will be central to determining whether this distributed architecture can meet the limitations of the claims.
- Intrinsic Evidence for a Broader Interpretation: The specification suggests that the claimed components may be distributed, stating that system elements "may physically reside within the same hardware" or be separate, and illustrates various software and hardware modules interacting across a network (’284 Patent, Fig. 1, Fig. 29). This may support a broad construction that a "computer" can be a logical system composed of multiple physical devices.
- Intrinsic Evidence for a Narrower Interpretation: The detailed description also refers to specific hardware like a "master server" and illustrates components in distinct boxes, which could support an argument that "a computer" refers to a more unitary piece of hardware rather than a diffuse collection of software applications running on various network elements (’284 Patent, Fig. 29, element 2800).
The Term: "suggested corrective action" / "suggests corrective action"
- Context and Importance: This term defines the ultimate output of the patented analysis. Whether the "adjustments" made by the accused Motorola system satisfy this limitation is a core infringement question.
- Intrinsic Evidence for a Broader Interpretation: The patents describe a wide range of potential "network tuning" applications, including adjusting transmit power and managing traffic, suggesting the term is intended to cover various types of network optimization (’284 Patent, col. 7:16-24; col. 67:1-17).
- Intrinsic Evidence for a Narrower Interpretation: The specification describes detailed diagnostic processes, including the generation of "case files" for specific fault conditions and flowcharts that lead to discrete corrective outputs (’284 Patent, Fig. 37, Fig. 38-A). This may support a narrower construction requiring a specific, identifiable recommendation rather than a continuous, background optimization process.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that Motorola induces infringement by actively encouraging and instructing its customers on how to use the accused products in an infringing manner (Compl. ¶¶9, 14).
- Willful Infringement: Willfulness is alleged based on both pre-suit and post-suit conduct. The complaint alleges post-suit knowledge from the filing of the lawsuit itself (Compl. ¶¶9, 14). It further alleges pre-suit knowledge based on a nearly decade-long history, including a 2007 supplier relationship and multiple instances where Motorola allegedly cited Traxcell's patent applications during the prosecution of its own patents (Compl. ¶¶9, 14).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of architectural scope: Can the "first computer" and "second computer" limitations, which form the structural backbone of the asserted claims, be read to cover Motorola's allegedly distributed system of various software applications (RFMS, SOLE) and hardware (switches, servers)? The case may turn on whether these disparate components function together as the claimed "computers."
- A key evidentiary question will be one of functional specificity: Does the accused system's general performance of network "adjustments" satisfy the more specific claim requirements of generating a "suggested corrective action" based on a defined "error code" or a comparison of "expected" and "actual" performance data? Plaintiff will need to produce evidence linking the operation of the accused products to these specific analytical steps.
- A third central question relates to willfulness: Do the allegations of a prior business relationship and citations in unrelated patent prosecution files establish pre-suit knowledge of infringement sufficient to support a claim for enhanced damages under the Halo standard? The court will have to determine if these facts demonstrate the "egregious" conduct necessary for such a finding.
