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”

• Issued: March 19, 2019 (’420 Patent)

The Invention Explained

• Problem Addressed: The patent’s background section describes inefficiencies in traditional call centers that use simple routing methods like first-come-first-served or longest-idle-agent (Compl. ¶9; ’420 Patent, col. 3:1-21). These legacy systems can fail to properly match callers with appropriately skilled agents, leading to problems such as routing a caller to an under-skilled agent (requiring a transfer) or an over-skilled agent (inefficiently using a valuable resource) (’420 Patent, col. 4:35-62).
• The Patented Solution: The invention proposes a method for matching a first entity (e.g., a caller) with a second entity (e.g., a call center agent) by treating the matching process as an auction (’420 Patent, Abstract). The system defines parameters for the caller (e.g., needs) and for a plurality of available agents (e.g., skills, cost) and performs an automated optimization. This optimization considers the "economic surplus" of a potential match and the "opportunity cost" of making an agent unavailable for other potential matches (’420 Patent, Abstract; Fig. 7).
• Technical Importance: This approach represents a shift from simple, queue-based logic to a dynamic, economically-driven optimization model for allocating communication resources in real-time (’420 Patent, col. 2:26-34).

Key Claims at a Glance

• The complaint does not identify the specific claims asserted but incorporates them by reference into an unprovided exhibit (Compl. ¶15, ¶17-18). Independent method claim 1 is representative of the patent’s core inventive concept.
• Essential elements of Independent Claim 1:
  • A method for matching a first entity with at least one second entity.
  • Defining a plurality of multivalued scalar data representing inferential targeting parameters for the first entity.
  • Defining a plurality of multivalued scalar data for each of a plurality of second entities, representing their characteristic parameters.
  • Performing an automated optimization with respect to an economic surplus of a respective match.
  • The optimization also considers an opportunity cost of the unavailability of the matched second entity for an alternate first entity.
• The complaint does not explicitly reserve the right to assert dependent claims but refers generally to infringement of "one or more claims" (Compl. ¶15).

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

• Issued: November 26, 2019 (’748 Patent)

The Invention Explained

• Problem Addressed: The patent identifies the same technical problems as the ’420 Patent regarding the inefficiencies of conventional call center routing and the difficulty of optimally matching callers to agents with the right skills in a dynamic environment (Compl. ¶10; ’748 Patent, col. 3:1-4:65).
• The Patented Solution: The ’748 Patent describes a communications routing system that determines an optimal routing between communication sources and targets by maximizing an "aggregate utility" (’748 Patent, Abstract). The system represents predicted characteristics of both sources and targets (e.g., callers and agents) and uses these representations to find the best match based on both economic and non-economic factors, such as skill-based matching and training opportunities (’748 Patent, col. 23:1-24:40; Fig. 1).
• Technical Importance: The invention integrates intelligent, multi-factorial analysis directly into the low-level communications switching architecture, aiming to reduce latency and reliance on external high-level management systems (’748 Patent, col. 18:8-21).

Key Claims at a Glance

• The complaint does not identify the specific claims asserted but incorporates them by reference into an unprovided exhibit (Compl. ¶21, ¶26-27). Independent claim 1 is representative of the system described.
• Essential elements of Independent Claim 1:
  • A communications routing system for representing predicted characteristics of communication sources and targets, each having an economic utility.
  • Determining an optimal routing between the sources and targets.
  • The determination is made by maximizing an aggregate utility with respect to the predicted characteristics.
  • The aggregate utility is represented by linkages between sources and destinations.
• The complaint refers generally to infringement of "one or more claims" of the patent (Compl. ¶21).

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

• Patent Identification: U.S. Patent No. 7,023,979, issued April 4, 2006 (’979 Patent) (Compl. ¶11).
• Technology Synopsis: This patent describes a communications management system that receives a communication, classifies it, and consults a database of agent skills and skill weights. It then computes an optimum agent selection and directly controls the routing of the communication to that agent (’979 Patent, Abstract).
• Asserted Claims: The complaint does not identify specific asserted claims, incorporating them by reference in the unprovided Exhibit 8 (Compl. ¶30, ¶32-33).
• Accused Features: The complaint does not specify which product features are accused of infringing this patent, referring only to "Exemplary Defendant Products" (Compl. ¶30).

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

• Patent Identification: U.S. Patent No. 7,269,253, issued September 11, 2007 (’253 Patent) (Compl. ¶12).
• Technology Synopsis: The ’253 Patent discloses a communications system and method where communications are received and classified. Characteristics of at least three potential targets are stored, and an optimum target is determined for each communication through a combinatorial optimization before routing (’253 Patent, Abstract).
• Asserted Claims: The complaint does not identify specific asserted claims, incorporating them by reference in the unprovided Exhibit 9 (Compl. ¶36, ¶38-39).
• Accused Features: The complaint does not specify which product features are accused of infringing this patent, referring only to "Exemplary Defendant Products" (Compl. ¶36).

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

• Patent Identification: U.S. Patent No. 9,456,086, issued September 27, 2016 (’086 Patent) (Compl. ¶13).
• Technology Synopsis: Similar to the ’420 Patent, this patent describes a method for matching entities by defining their parameters using multivalued scalar data. It then performs an automated optimization based on the economic surplus of a match and the opportunity cost of making one entity unavailable for other potential matches (’086 Patent, Abstract).
• Asserted Claims: The complaint does not identify specific asserted claims, incorporating them by reference in the unprovided Exhibit 10 (Compl. ¶42, ¶47-48).
• Accused Features: The complaint does not specify which product features are accused of infringing this patent, referring only to "Exemplary Defendant Products" (Compl. ¶42).

III. The Accused Instrumentality

• Product Identification: The complaint does not identify any accused product, method, or service by name (Compl. ¶15, ¶21, ¶30, ¶36, ¶42). It refers generically to "Exemplary Defendant Products," which are purportedly identified in claim chart exhibits that were not filed with the complaint (Compl. ¶17, ¶26, ¶32, ¶38, ¶47).
• Functionality and Market Context: The complaint does not provide sufficient detail for analysis of the functionality of the accused instrumentalities. It makes only conclusory allegations that the unnamed products "practice the technology claimed" by the patents-in-suit (e.g., Compl. ¶17, ¶26). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint alleges direct infringement of all five patents-in-suit. For each patent, the complaint states that infringement is detailed in a corresponding claim chart exhibit (Exhibits 6-10) which is incorporated by reference (Compl. ¶18, ¶27, ¶33, ¶39, ¶48). As these exhibits were not provided, a detailed analysis of the infringement allegations is not possible. The narrative infringement theory is limited to the conclusory statement that Defendant’s products "satisfy all elements" of the asserted claims (e.g., Compl. ¶17).

• Identified Points of Contention: Based on the language of the patents and the identity of the Defendant, the central infringement dispute may involve fundamental mismatches between the claimed subject matter and the Defendant's activities.
  • Scope Questions: A primary question will be whether the commercially-focused language of the patents can be construed to read on the operations of a non-profit organization. For the ’420 and ’086 Patents, this raises the question of whether the Defendant’s systems perform an "auction" or calculate an "economic surplus" and "opportunity cost" as those terms are used in the claims.
  • Technical Questions: A key evidentiary question will be whether the Defendant's communication systems perform the specific, multi-factorial optimizations required by the claims. For the ’748, ’979, and ’253 Patents, this raises the question of whether Defendant’s systems go beyond standard call routing to perform the claimed "intelligent," "cost-utility," or "combinatorial" optimizations.

V. Key Claim Terms for Construction

• For the ’420 and ’086 Patents:

  • The Term: "economic surplus"
  • Context and Importance: This term is central to the claimed optimization process. Its construction will be critical because the Defendant, a non-profit, may argue that its systems are not designed to, and do not, calculate or optimize for commercial or economic outcomes in the manner described by the patent. Practitioners may focus on this term to determine if non-commercial goals, such as connecting a person to the best medical information source, can constitute an "economic surplus."
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification discusses "utility functions" and "business goals" which could be interpreted more broadly than direct monetary profit, potentially including factors like "customer satisfaction" (’420 Patent, col. 24:30-40).
    • Evidence for a Narrower Interpretation: The specification repeatedly frames the invention in commercial terms, referencing "sales volume, profit, or the like" and normalizing factors into "economic units" (’420 Patent, col. 24:35-39). The use of the word "economic" itself suggests a nexus to commerce or monetary value.

• For the ’748, ’979, and ’253 Patents:

  • The Term: "optimizing a cost-utility function" (or similar phrases like "combinatorial optimization")
  • Context and Importance: This term defines the nature of the claimed intelligent routing. The dispute will likely center on the degree of complexity and analysis required to meet this limitation. Defendant may argue its system employs simple, rules-based routing that does not rise to the level of "optimizing" a multi-variable "cost-utility function."
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent notes that the optimization may be "simplistic" in some analyses and can be based on factors like minimizing caller hold time, which is a common feature of many routing systems (’748 Patent, col. 22:7-12; col. 24:64-67).
    • Evidence for a Narrower Interpretation: The specification details a complex, multi-variable cost function that includes not only agent skill and cost, but also anticipated transaction value and opportunity costs, suggesting a highly sophisticated calculation is required (’748 Patent, col. 24:53-61). The patent distinguishes its invention from simpler "traditional skill based call routing" (’748 Patent, col. 36:16-18).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the ’748 and ’086 Patents. The allegations are based on Defendant’s distribution of "product literature and website materials inducing end users and others to use its products in the customary and intended manner that infringes" the patents (Compl. ¶24, ¶45). The complaint references Exhibits 7 and 10 as providing extensive support for these allegations (Compl. ¶24, ¶46).
• Willful Infringement: The complaint alleges that service of the complaint itself constitutes "actual knowledge" of infringement for the ’748 and ’086 Patents (Compl. ¶23, ¶44). The continued alleged infringement after this date is asserted as the basis for willfulness. No allegations of pre-suit knowledge are made.

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

1. A core issue will be one of definitional scope: can the commercially-oriented claim language of the patents-in-suit, particularly terms like "auction" and "economic surplus," be construed to cover the communication routing activities of a non-profit organization like the American Heart Association, which may prioritize informational or service outcomes over commercial ones?
2. A second key issue will be one of evidentiary sufficiency: as the complaint pleads infringement in a conclusory manner while relying entirely on unprovided exhibits, a central question for discovery will be whether Plaintiff can produce sufficient technical evidence to demonstrate that Defendant’s systems actually perform the specific, multi-step, auction-based or combinatorial optimizations required by the claims, as opposed to more conventional call routing methods.
