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

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

• Patent Identification: U.S. Patent No. 10,237,420, "Method and system for matching entities in an auction," issued March 19, 2019.

The Invention Explained

• Problem Addressed: The patent's background describes inefficiencies in traditional call centers that use simple queuing logic, such as first-come-first-served, which can result in mismatches between a caller's needs and an agent's skills, leading to under-skilled or over-skilled agent assignments and reduced transactional throughput (’420 Patent, col. 4:1-34).
• The Patented Solution: The invention proposes a system for matching a first entity (e.g., a caller) with a second entity (e.g., an agent) by performing an "automated optimization." This optimization considers not only the "economic surplus" of a potential match but also the "opportunity cost" of making that agent unavailable for other potential matches. The system uses "multivalued scalar data" to represent the characteristics of each entity in the optimization process (’420 Patent, Abstract; col. 1:57-67).
• Technical Importance: This approach seeks to replace static routing rules with a dynamic, economic-based model to improve the overall efficiency and value of resource allocation in a communications network (’420 Patent, col. 18:8-21).

Key Claims at a Glance

• The complaint asserts "one or more claims" of the patent (Compl. ¶15). Independent claim 1 is representative.
• Claim 1 includes the following essential elements:
  • defining a plurality of multivalued scalar data representing inferential targeting parameters for the first entity;
  • defining a plurality of multivalued scalar data representing respective characteristic parameters for each of a plurality of second entities;
  • performing an automated optimization with respect to an economic surplus of a respective match of the first entity with at least one of the second entities; and
  • performing the automated optimization with respect to an opportunity cost of the unavailability of the at least one of the plurality of second entities for matching with an alternate first entity.
• The complaint does not explicitly reserve the right to assert dependent claims.

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

• Patent Identification: U.S. Patent No. 10,491,748, "Intelligent communication routing system and method," issued November 26, 2019.

The Invention Explained

• Problem Addressed: The patent addresses the limitations of conventional call center management, which often fails to balance competing goals such as providing high-quality customer service while making efficient use of call center resources (’748 Patent, col. 2:25-34).
• The Patented Solution: The invention is a communications routing system that models both "communications sources" and "communications targets" using "predicted characteristics," each associated with an "economic utility." The system determines an "optimal routing" by "maximizing an aggregate utility" based on these characteristics (’748 Patent, Abstract). This optimization can incorporate long-term goals, such as agent training, by factoring in metrics like "expected incremental training utility" alongside short-term efficiency (’748 Patent, Fig. 2; col. 24:28-42).
• Technical Importance: The technology provides a framework for routing decisions that balances immediate transactional efficiency with longer-term strategic objectives for the call center, such as workforce development (’748 Patent, col. 27:8-14).

Key Claims at a Glance

• The complaint asserts "one or more claims" of the patent (Compl. ¶21). Independent claim 1 is representative.
• Claim 1 includes the following essential elements:
  • a plurality of communications channels for concurrently communicating with a plurality of entities;
  • a communications router that performs steps including:
  • representing a plurality of predicted characteristics of a plurality of communications sources, each having an economic utility;
  • representing a plurality of predicted characteristics of a plurality of communications targets, each having an economic utility; and
  • determining an optimal routing between the sources and targets by maximizing an aggregate utility with respect to the respective predicted characteristics.
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 7,023,979 - "Telephony control system with intelligent call routing"

• Technology Synopsis: This patent describes a telephony control system for intelligent call routing. It addresses the problem of inefficiently matching callers to agents in a call center by proposing a system that can optimize agent selection based on a cost-utility function, factoring in long-term goals like agent training in addition to short-term efficiency (’979 Patent, col. 23:41-51).
• Asserted Claims: The complaint asserts "one or more claims" (Compl. ¶30).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" but does not name specific products or features (Compl. ¶30).

U.S. Patent No. 7,269,253 - "Telephony control system with intelligent call routing"

• Technology Synopsis: This patent, related to the ’979 patent, also discloses a system for intelligent call routing. The invention focuses on optimizing agent selection in a call center by using a cost-benefit analysis that can account for various factors, including agent skills, call characteristics, and call center capacity, to move beyond simple first-in, first-out queuing (’253 Patent, col. 7:42-52).
• Asserted Claims: The complaint asserts "one or more claims" (Compl. ¶36).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" but does not name specific products or features (Compl. ¶36).

U.S. Patent No. 9,456,086 - "Method and system for matching entities in an auction"

• Technology Synopsis: This patent, related to the ’420 patent, describes a method for matching entities using an auction framework. The system performs an automated optimization based on the "economic surplus" of a potential match and the "opportunity cost" of assigning a resource, thereby seeking to achieve a more globally efficient allocation than traditional routing methods (’086 Patent, Abstract).
• Asserted Claims: The complaint asserts "one or more claims" (Compl. ¶42).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" but does not name specific products or features (Compl. ¶42).

III. The Accused Instrumentality

• Product Identification: The complaint refers to "Exemplary Defendant Products" that are allegedly identified in claim charts attached as exhibits (Compl. ¶15, 21, 30, 36, 42). However, the complaint text does not name or describe any specific accused product, method, or service.
• Functionality and Market Context: The complaint does not provide sufficient detail for analysis of the functionality or market context of any accused instrumentality.

IV. Analysis of Infringement Allegations

The complaint's substantive infringement allegations for all five patents-in-suit are contained within Exhibits 6, 7, 8, 9, and 10, which are incorporated by reference but are not attached to the publicly filed complaint document (Compl. ¶17-18, 26-27, 32-33, 38-39, 47-48). The body of the complaint offers only conclusory statements that the "Exemplary Defendant Products practice the technology claimed" by the patents-in-suit. Because these exhibits are not provided and no narrative infringement theory is presented in the complaint, a claim chart summary cannot be created.

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Scope Questions: Based on the language of the asserted patents, a central question may be how abstract, economics-derived terms such as "economic surplus" ('420 Patent) and "aggregate utility" (’748 Patent) are defined and applied in the context of a technical system. The dispute may focus on whether the accused systems perform optimizations that meet the specific definitions of these terms as construed by the court.
  • Technical Questions: An evidentiary question will be whether the accused systems actually perform the multi-factorial, dynamic optimizations required by the claims. For example, the complaint does not provide facts to show that an accused system calculates "opportunity cost" (’420 Patent) or maximizes a utility function that includes factors like agent training (’748 Patent), as opposed to using more conventional routing rules.

V. Key Claim Terms for Construction

• The Term: "economic surplus" (’420 Patent, Claim 1)

• Context and Importance: This term is the primary objective of the claimed optimization. The outcome of the infringement analysis for the ’420 Patent may depend on whether the function optimized by the accused system can be characterized as an "economic surplus." Practitioners may focus on this term because its construction will define the type of calculation required to infringe.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification does not provide an explicit definition, which may suggest the term should be given its plain and ordinary meaning from the field of economics, potentially covering any calculation of net benefit or value (’420 Patent, col. 21:1-15).
  • Evidence for a Narrower Interpretation: The specification describes the optimization in the context of a "cost-utility function" that considers factors such as agent costs, training costs, and anticipated outcomes, which could support a narrower construction requiring a specific type of multi-factor financial calculation (’420 Patent, col. 24:1-42).

• The Term: "maximizing an aggregate utility" (’748 Patent, Claim 1)

• Context and Importance: This limitation defines the core function of the claimed communications router. Infringement will depend on whether the accused system's routing logic performs an operation that can be considered "maximizing an aggregate utility." A defendant could argue its system follows simpler, heuristic rules that do not rise to the level of "maximization."

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: Language describing the goal of satisfying a customer at the lowest cost to the company could support a broader view where any process that improves overall business efficiency is "maximizing" a utility (’748 Patent, col. 27:25-31).
  • Evidence for a Narrower Interpretation: The patent provides a detailed formula for an "optimum" selection that includes terms for agent cost, anticipated change in agent value, anticipated transaction value, and opportunity cost, suggesting that "maximizing an aggregate utility" requires a specific, multi-part quantitative optimization (’748 Patent, col. 24:50-58).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the ’748 and ’086 Patents. 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" (Compl. ¶24, 45).
• Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. It alleges "Actual Knowledge of Infringement" for the ’748 and ’086 Patents, but states this knowledge arises from "the service of this Complaint" (Compl. ¶23, 44). These facts, if proven, may support a claim for enhanced damages for post-suit infringement but do not establish pre-suit knowledge.

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

• A core issue will be one of evidentiary sufficiency: As the complaint makes only bare allegations and relies entirely on unincorporated exhibits, a key question will be whether Plaintiff can produce sufficient factual evidence in discovery to demonstrate that Defendant's unspecified systems perform the specific, complex, and economically-driven optimization functions recited in the patent claims.
• A central legal issue will be one of definitional scope: The case will likely turn on the construction of abstract terms like "economic surplus," "opportunity cost," and "aggregate utility." The key question for the court will be whether these terms should be interpreted broadly to cover general-purpose business optimization or narrowly to require the specific multi-factor calculations and economic models detailed in the patent specifications.
