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

U.S. Patent No. 8,589,541 - "Device-assisted services for protecting network capacity" (issued Nov. 19, 2013)

The Invention Explained

• Problem Addressed: The patent’s background section describes the problem of wireless network capacity being overwhelmed by increasing data consumption from mobile devices, particularly from applications that frequently access the network for small data transfers, which degrades overall network performance (Compl. ¶¶ 11-13; ’541 Patent, col. 10:8-20, col. 13:58-67).
• The Patented Solution: The invention provides for a non-transitory computer-readable storage medium on a wireless device containing instructions for a "service processor." This processor identifies service usage by software on the device, determines a policy for controlling that usage (e.g., based on whether it is "background activity"), and applies the policy to protect network capacity, for example by throttling or blocking certain data traffic when the network is busy (Compl. ¶¶ 15, 29; ’541 Patent, Abstract, col. 17:45-59).
• Technical Importance: This device-assisted approach enables more granular and context-aware traffic management than purely network-centric solutions, helping carriers reduce data usage and congestion while extending device battery life (Compl. ¶15).

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 (Compl. ¶65).
• Claim 1 is directed to a non-transitory computer-readable storage medium on a wireless end-user device, with machine-executable instructions that cause one or more processors to:
  • Identify a service usage activity of a first software component, where the activity includes one or more successful communications over a wireless network.
  • Determine at least an aspect of a policy based on the identified service usage activity, where the policy is to be applied if the device is connected to the wireless network.
  • The policy aspect includes a control for controlling the service usage activity.
  • If it is determined that the service usage activity is a background activity, apply the policy.
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 8,924,543 - "Service design center for device assisted services" (issued Dec. 30, 2014)

The Invention Explained

• Problem Addressed: The patent addresses the challenge that creating, implementing, and managing network service plans for end-user devices is often a rigid, time-consuming, and error-prone process for network operators ('543 Patent, col. 7:38-8:2).
• The Patented Solution: The invention provides a method and system for a "service design center" that allows for the modular creation of service plans. The system uses "filters" to identify specific types of network traffic, which are then used to generate "service objects." These objects, along with associated policies (e.g., for charging or access), are assembled into service plans, which are then organized into catalogs for specific subscriber groups. The system includes a graphical user interface to facilitate this design process ('543 Patent, Abstract; Fig. 1). The complaint includes a screenshot from the '543 patent's prosecution history showing a user interface for such a service design system (Compl. p. 6).
• Technical Importance: This technology allows network carriers to more flexibly and rapidly create, test, and deploy customized and granular service plan offerings to different user segments, enabling new business models (Compl. ¶14).

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 (Compl. ¶79).
• Claim 1 is directed to a method comprising the steps of:
  • Identifying, at a service design system, one or more filters for identifying network data traffic associated with network services.
  • Generating one or more service objects using the filters, with each object identifying traffic for a category of network services.
  • Generating a service plan using the service objects for managing the use of network services by an end-user device.
  • Associating at least one sub-plan-level policy with at least one of the filters or service objects, which defines rules of use.
  • Using the filters and the policy to generate computer code for assisting a policy implementation element on the end-user device.
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 9,198,042 - "Security techniques for device assisted services" (issued Nov. 24, 2015)

• Technology Synopsis: The '042 Patent is directed to security methods for device-assisted services. The invention involves receiving a report from an end-user device about its "service state." Based on this report, a determination is made as to whether a "service policy setting" on the device needs to be modified. If so, configuration information is sent to the device to perform the modification. A central aspect is that the service policy setting is stored in a "protected partition" on the device, which is configured to deter or prevent unauthorized modifications, thereby ensuring the integrity of the on-device policy enforcement agent (’042 Patent, Abstract).
• Asserted Claims: Independent claim 1 (Compl. ¶93).
• Accused Features: Verizon's system of mobile devices, networks, and servers that allegedly use secure, server-controlled policies that are enforced on end-user devices (Compl. ¶89).

U.S. Patent No. 9,215,613 - "Wireless end-user device with differential traffic control policy list having limited user control" (issued Dec. 15, 2015)

• Technology Synopsis: The '613 Patent describes a wireless end-user device with both WWAN and WLAN modems. The device uses a "differential traffic control policy list" to determine whether to apply traffic controls (e.g., blocking) to an application's Internet activity, particularly based on whether the application is interacting with the user in the foreground. The invention provides a user interface that allows the user to "augment" the policy for certain specified applications, but not for others, thereby providing limited, rather than complete, user control over the traffic policies (’613 Patent, Abstract).
• Asserted Claims: Independent claim 1 (Compl. ¶107).
• Accused Features: Verizon's mobile devices and associated systems that allegedly use differential policies to control application traffic and provide users with some degree of control over those policies (Compl. ¶103).

III. The Accused Instrumentality

Product Identification

• The Accused Instrumentalities are broadly defined as "mobile electronic devices, including mobile phones and tablets," as well as the "cellular networks, servers, and services" made, used, or sold by Verizon (Compl. ¶1, ¶46).

Functionality and Market Context

• The complaint alleges that the accused products and services incorporate functionalities that help manage device data usage to reduce network congestion, extend battery life, and provide flexible service plan options (Compl. ¶15). These instrumentalities are alleged to operate by monitoring application data usage on the device, classifying the usage, and applying network-defined policies to control data access. The complaint includes a screenshot of a Verizon coverage map for Marshall, Texas to support its allegation that Verizon's accused wireless network services are available in the district (Compl. ¶52, p. 15). To support its allegation that Verizon sells accused devices in the district, the complaint provides a screenshot from Verizon's website showing retail store locations near Marshall, Texas (Compl. ¶54, p. 16).

IV. Analysis of Infringement Allegations

The complaint references claim chart exhibits that were not provided with the filing; therefore, the narrative infringement theories are summarized below in prose.

• '541 Patent Infringement Theory
  The complaint alleges that Verizon's devices and services infringe by implementing the claimed method for device-assisted network protection (Compl. ¶¶60, 65). The narrative theory suggests that software on Verizon's mobile devices, when executed by the device processors, identifies network communications by applications, determines whether this constitutes "background activity" based on a policy, and applies a control to that activity. This functionality is alleged to map to features in modern mobile operating systems that manage background data usage to conserve data and battery life, which are controlled by policies set by Verizon's network (Compl. ¶15).

• '543 Patent Infringement Theory
  The complaint alleges that Verizon's back-end systems for creating and provisioning service plans infringe the claimed method for a "service design center" (Compl. ¶¶74, 79). The theory is that Verizon utilizes a system to define "filters" (e.g., criteria identifying video streaming traffic), generate "service objects" (e.g., a rule set for video streaming), and assemble these into "service plans" (e.g., a plan with specific rules for video data). This system then allegedly generates the "computer code" or policies that are transmitted to and implemented on end-user devices to enforce the terms of the purchased service plan (Compl. ¶14).

• Identified Points of Contention:

  • Scope Questions: For the ’543 Patent, a potential dispute is whether Verizon's platform for creating service plans meets the definition of a "service design system" that "generat[es] one or more service objects" as claimed. The analysis may focus on whether Verizon's system uses the specific modular architecture described in the patent or a conventional, integrated network management system.
  • Technical Questions: For the ’541 Patent, a central question may be whether the accused devices perform an on-device "determin[ation]" of the policy, as required by the claim, or if they merely receive and execute a fully-formed policy from Verizon's network servers. The infringement analysis will turn on the specific software architecture and locus of decision-making in the accused system.

V. Key Claim Terms for Construction

• For the ’541 Patent (Claim 1):

  • The Term: "determine, determining at least an aspect of a policy based on the identified service usage activity"
  • Context and Importance: The construction of this term is critical because infringement may depend on whether the accused device performs an active "determination" regarding the policy to be applied, or if it acts as a passive enforcement agent for policies dictated entirely by the network. Practitioners may focus on this term because it addresses the core inventive concept of shifting some network management intelligence to the device.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification suggests an active role for the on-device service processor, stating it can implement policies based on "a network busy state, time based criteria, and/or other criteria/measures" ('541 Patent, col. 78:48-52). This may support a construction where evaluating conditions on the device constitutes "determining."
    • Evidence for a Narrower Interpretation: The specification repeatedly describes the network "service controller" as the entity that "manages policy settings on the device" ('541 Patent, col. 49:7-8). This may support a narrower construction where "determining" requires creating or selecting the substance of the policy, a function potentially performed only by the network server.

• For the ’543 Patent (Claim 1):

  • The Term: "generating one or more service objects using the one or more filters"
  • Context and Importance: This term is central to the claimed invention's modular approach to creating service plans. The dispute will likely focus on whether Verizon's system for creating data plans has the specific two-step "generating" architecture required by the claim.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent abstract describes the technique in broad functional terms, such as "modular storage of network service plan components." This language may support a construction where any system that logically groups traffic rules ("filters") into reusable components ("service objects") infringes.
    • Evidence for a Narrower Interpretation: Figure 2 of the patent depicts a specific architecture with distinct datastores for "Filters," "Components," and "Plans," suggesting a structured, multi-stage process ('543 Patent, Fig. 2). This may support a narrower construction requiring an accused system to explicitly create a distinct "service object" data structure from a "filter" data structure.

VI. Other Allegations

• Indirect Infringement: The complaint alleges that Verizon induces infringement by "actively encouraging others (including its customers) to use, offer to sell, sell, and import the Accused Instrumentalities" and providing instructions for their use (Compl. ¶¶ 67, 81, 95, 109).
• Willful Infringement: Willfulness is alleged for all four patents. The complaint provides a detailed factual basis, alleging that Verizon had pre-suit knowledge of the patented technology through a multi-year business relationship with Plaintiff's affiliate, ItsOn Inc., which included technical presentations, a paid software license and evaluation, prototype field trials, and an equity investment (Compl. ¶¶ 17-29). The complaint further alleges that Verizon's own patent application was rejected in view of the application for the '541 patent, providing another potential source of knowledge (Compl. ¶¶ 35-36, 63).

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

• A core issue will be one of historical evidence and independent development: Given the detailed allegations of a multi-year technical and business collaboration, a central question for the court will be factual: can Verizon demonstrate that its accused data management systems were developed independently, or will the evidence suggest they were derived from the intellectual property disclosed by Headwater and ItsOn during the alleged partnership?
• A key legal question will be one of architectural equivalence: Can the patent claims, which recite specific software architectures such as an on-device policy "determination" ('541 Patent) and a modular "service object" generation system ('543 Patent), be construed to read on the potentially different architectures of Verizon's large-scale commercial platforms? The outcome may depend on whether the accused systems perform the same functions in substantially the same way as recited in the claims.
