Case Timeline

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

U.S. Patent No. 10,237,420 - "Method and system for matching entities in an auction"

The Invention Explained

• Problem Addressed: The patent describes the inefficiency of traditional call center routing systems, such as first-come-first-served, which fail to account for the varying skills of agents. While skill-based routing exists, it presents complex challenges in optimally matching callers to agents in real-time, especially when considering factors like agent cost, scheduling, and overall call center efficiency (US10237420B1, col. 3:1-4:34).
• The Patented Solution: The invention proposes a system that treats the matching of a "first entity" (e.g., a caller) with a "second entity" (e.g., an agent) as a real-time auction. The system performs an "automated optimization" that considers not only the "economic surplus" of a potential match but also the "opportunity cost" of making a particular agent unavailable for other potential calls. This is achieved by defining parameters for both callers and agents as "multivalued scalar data" and using them in a cost-benefit analysis to determine the optimal routing decision ('420 Patent, Abstract; Fig. 3).
• Technical Importance: The technology aims to move beyond simple rule-based routing to a more dynamic, holistic optimization that can improve efficiency and outcomes in complex, multi-skilled communications environments ('420 Patent, col. 21:5-22:2).

Key Claims at a Glance

• The complaint does not identify specific asserted claims, instead referring to "exemplary claims" in non-public exhibits (Compl. ¶15). Independent claim 1 is representative of the invention.
• Claim 1 requires, in summary:
  • Defining multivalued scalar data for a first entity (representing inferential targeting parameters).
  • Defining multivalued scalar data for each of a plurality of second entities (representing characteristic parameters).
  • Performing an automated optimization with respect to an economic surplus of a match and an opportunity cost of the unavailability of the second entity for an alternate match.

U.S. Patent No. 10,491,748 - "Intelligent communication routing system and method"

The Invention Explained

• Problem Addressed: The patent addresses the same technical problem as the '420 Patent: the limitations of conventional call center management and the need for more intelligent, efficient routing systems that can handle agents with diverse skills and training levels ('748 Patent, col. 1:26-2:50).
• The Patented Solution: The invention is a communications routing system that models both communications sources (e.g., callers) and targets (e.g., agents) based on their predicted characteristics and an associated "economic utility." The system determines an optimal routing path by "maximizing an aggregate utility" considering these characteristics. The specification details how a "cost-utility function" can be optimized for either short-term efficiency or long-term goals like agent training ('748 Patent, Abstract; Fig. 1).
• Technical Importance: This approach provides a framework for routing decisions that can balance immediate transactional efficiency with longer-term strategic objectives, such as workforce development, within a communications network ('748 Patent, col. 27:8-28:40).

Key Claims at a Glance

• The complaint does not identify specific asserted claims (Compl. ¶21). Independent claim 1 is representative.
• Claim 1 requires, in summary:
  • Estimating at least one characteristic associated with a request.
  • Determining a set of available partners with respective characteristics.
  • Evaluating pairings of the request with partners using an automated processor and an "evaluator for valuing pairings."
  • Generating a control signal dependent on the evaluation to control pairing.

Multi-Patent Capsule: U.S. Patent 7,023,979 - "Telephony control system with intelligent call routing"

• Technology Synopsis: This patent, a parent to the '253 Patent, discloses a foundational intelligent call routing system. It describes receiving a "communications classification," accessing a database of "skill weights" and "agent skill scores," and using a processor to compute an optimal agent selection to control call routing ('979 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims (Compl. ¶30). Independent claims are 1, 19, and 20.
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in a non-public exhibit (Compl. ¶30).

Multi-Patent Capsule: U.S. Patent 7,269,253 - "Telephony control system with intelligent call routing"

• Technology Synopsis: As a continuation of the '979 Patent, this patent covers a similar system for optimizing call routing. The invention involves receiving communications with associated classifications, storing characteristics of potential targets (agents), and performing a combinatorial optimization to determine the best match based on a cost-benefit analysis ('253 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims (Compl. ¶39). Independent claims are 1 and 21.
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in a non-public exhibit (Compl. ¶39).

Multi-Patent Capsule: U.S. Patent 9,456,086 - "Method and system for matching entities in an auction"

• Technology Synopsis: This patent, a parent to the '420 Patent, discloses a method for matching entities by defining their characteristics as "multivalued scalar data" and performing an "automated optimization." The optimization considers the "economic surplus" of a potential match and the "opportunity cost" of forgoing alternative matches, effectively creating a real-time auction for routing communications ('086 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims (Compl. ¶45). Independent claims are 1 and 19.
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in a non-public exhibit (Compl. ¶45).

III. The Accused Instrumentality

• Product Identification: The complaint does not identify any specific accused products, methods, or services by name. It refers generically to "Exemplary Defendant Products" (Compl. ¶15, 21, 30, 39, 45).
• Functionality and Market Context: The complaint does not provide sufficient detail for analysis of the accused instrumentality's functionality. It alleges that the unspecified products are identified in claim chart exhibits (Exhibits 6-10) which were not filed publicly with the complaint (Compl. ¶17, 26, 35, 41, 50). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint incorporates by reference claim chart exhibits that are not publicly available (Compl. ¶18, 27, 36, 42, 51). The narrative infringement theory is limited to conclusory statements that the "Exemplary Defendant Products practice the technology claimed" by the patents-in-suit and "satisfy all elements" of the asserted claims (e.g., Compl. ¶17, 26). Without the specific product details or the claim charts, a detailed infringement analysis is not possible based on the provided documents.

• Identified Points of Contention:
  • Scope Questions: The asserted patents are largely described in the context of telecommunications and call centers. A central question may be whether the scope of terms like "auction," "first entity," "second entity," and "call routing," as defined in the patents, can be construed to read on the unspecified business processes of an insurance company.
  • Technical Questions: The patents claim specific, multi-factorial "automated optimization" processes that weigh factors like "economic surplus" and "opportunity cost" ('420 Patent, Claim 1) or maximize an "aggregate utility" ('748 Patent, Abstract). A key technical question will be what evidence demonstrates that the accused systems perform these specific computational optimizations, as opposed to employing more conventional, static rule-based processing.

V. Key Claim Terms for Construction

• The Term: "automated optimization with respect to an economic surplus ... and an opportunity cost" (from '420 Patent, Claim 1).
• Context and Importance: This phrase encapsulates the core of the '420 and '086 patents' inventive concept. The construction of this term will be critical to determining infringement, as it defines the specific type of calculation the accused system must perform. Practitioners may focus on this term because its definition will distinguish the patented invention from simpler, prior art routing methods.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent uses broad language like "first entity" and "second entity" and discusses the invention's applicability to various "communications" ('420 Patent, col. 1:47-57), which may support an interpretation not strictly limited to traditional call centers.
  • Evidence for a Narrower Interpretation: The detailed description and figures are heavily rooted in the call center context, repeatedly referencing "callers," "agents," "skill-based routing," and "call center operation" ('420 Patent, Fig. 1; col. 2:25-44). This context may support a narrower construction requiring a specific type of economic modeling related to call center efficiency metrics.
• The Term: "evaluator for valuing pairings" (from '748 Patent, Claim 1).
• Context and Importance: This term defines the required decision-making engine in the '748 Patent. The dispute may turn on whether any system that applies rules to match requests infringes, or if the "evaluator" must perform a specific type of multi-factor, utility-based calculation as described in the specification.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself is functional and does not explicitly limit the "evaluator" to a specific algorithm, which could support a broad reading on any component that assesses and ranks potential pairings.
  • Evidence for a Narrower Interpretation: The specification describes the evaluation process in terms of optimizing a "cost-utility function" that can include disparate factors like agent training, productivity, and business goals, all "normalized into a common metric" ('748 Patent, col. 23:24-24:22). This detailed description may support a narrower construction requiring a multi-factorial, economic-based assessment.

VI. Other Allegations

• Indirect Infringement: For the '748, '979, and '086 Patents, the complaint alleges induced infringement. The allegations are based on Defendant distributing "product literature and website materials inducing end users and others to use its products in the customary and intended manner" that infringes (Compl. ¶24, 33, 48).
• Willful Infringement: The complaint alleges "Actual Knowledge of Infringement" for the '748, '979, and '086 Patents based on "the service of this Complaint, in conjunction with the attached claim charts" (Compl. ¶23, 32, 47). This forms a basis for potential post-suit willful infringement allegations. No pre-suit knowledge is alleged.

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

• A core issue will be one of definitional scope: can terms like "auction," "economic surplus," and "call routing," which are defined and exemplified in the patents' specifications almost exclusively within the technical context of telecommunications call centers, be construed broadly enough to cover the unspecified business systems and processes of an insurance company?
• A key evidentiary question will be one of technical operation: given the complaint's lack of specificity regarding the accused products, the case will likely depend on evidence developed during discovery to determine whether Defendant’s systems actually perform the specific, multi-factorial, economic-based "automated optimization" required by the claims, or if they operate using fundamentally different, non-infringing logic.
