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 Mar. 19, 2019)

• The Invention Explained:

  • Problem Addressed: The patent addresses the inefficiencies in traditional call centers, which often use simple "first-come-first-served" logic to route calls. This can lead to mismatches, such as routing a caller to an under-skilled agent (requiring a transfer) or an over-skilled agent (wasting a valuable resource) ('420 Patent, col. 4:35-61).
  • The Patented Solution: The invention proposes a method for matching a "first entity" (e.g., an incoming call) with the optimal "second entity" (e.g., a call center agent) from a pool of available options. This is achieved by defining characteristics for both sets of entities using "multivalued scalar data" and then performing an "automated optimization" that considers not only the best match but also the "economic surplus" generated by that match and the "opportunity cost" of making a particular agent unavailable for other potential matches ('420 Patent, Abstract; col. 20:25-52).
  • Technical Importance: The technology represents a move from static, queue-based call distribution to dynamic, economically optimized resource allocation in real-time communications environments (Compl. ¶9).

• Key Claims at a Glance:

  • The complaint asserts infringement of one or more claims, with specific claims identified in an exhibit not provided with the complaint (Compl. ¶15). The analysis here focuses on Claim 1 as a representative independent claim.
  • Claim 1 (Method):
    • Defining a plurality of multivalued scalar data representing inferential targeting parameters for a 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 match between the first and a second entity.
    • The optimization also considers an opportunity cost of the unavailability of the selected second entity for matching with an alternate first entity.
  • The complaint reserves the right to assert additional claims, including dependent claims (Compl. ¶15).

U.S. Patent No. 10,491,748 - "Intelligent communication routing system and method" (Issued Nov. 26, 2019)

• The Invention Explained:

  • Problem Addressed: The patent family addresses the limitations of conventional call routing systems that fail to account for the unique skills of agents and the specific needs of callers, leading to suboptimal pairings and inefficient call center operation ('420 Patent, col. 2:26-34, incorporated by reference into the '748 Patent family).
  • The Patented Solution: The invention describes a method for routing communications by representing both sources (e.g., callers) and targets (e.g., agents) with a set of predicted characteristics, each associated with an "economic utility." The system then determines an optimal routing path by "maximizing an aggregate utility" that takes these characteristics into account ('748 Patent, Abstract). This allows for a more granular and intelligent matching process than traditional methods. The system architecture, as shown in Figure 1, outlines a process flow for optimizing a cost-utility function for call center operations ('748 Patent, Fig. 1).
  • Technical Importance: This technology aims to improve the efficiency and effectiveness of large-scale communication hubs by applying economic principles and predictive analytics to the real-time task of call routing (Compl. ¶10).

• Key Claims at a Glance:

  • The complaint asserts infringement of one or more claims, with specific claims identified in an exhibit not provided with the complaint (Compl. ¶21). The analysis here focuses on Claim 1 as a representative independent claim.
  • Claim 1 (Method):
    • 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.
    • Determining an optimal routing between the sources and targets by maximizing an aggregate utility with respect to their predicted characteristics.
  • The complaint reserves the right to assert additional claims, including dependent claims (Compl. ¶21).

Multi-Patent Capsules

• U.S. Patent No. 7,023,979: "Telephony control system with intelligent call routing" (Issued Apr. 4, 2006)

  • Technology Synopsis: This patent, an ancestor to the others in the suit, discloses a system for intelligent call routing in a telephony control system. It addresses the problem of matching callers with appropriately skilled agents by optimizing a "cost-utility function" that considers factors beyond simple call queuing, including agent training and long-term call center operational goals ('979 Patent, Abstract; col. 18:8-23).
  • Asserted Claims: One or more claims, with specifics identified in a non-provided exhibit (Compl. ¶30).
  • Accused Features: Defendant's "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶30).

• U.S. Patent No. 7,269,253: "Telephony control system with intelligent call routing" (Issued Sep. 11, 2007)

  • Technology Synopsis: As a continuation of the '979 patent, this patent further details a system for intelligent call routing based on combinatorial optimization. It describes determining an optimum target for a communication by comparing the characteristics of the communication with those of a plurality of potential targets to find the best match ('253 Patent, Abstract).
  • Asserted Claims: One or more claims, with specifics identified in a non-provided exhibit (Compl. ¶39).
  • Accused Features: Defendant's "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶39).

• U.S. Patent No. 9,456,086: "Method and system for matching entities in an auction" (Issued Sep. 27, 2016)

  • Technology Synopsis: This patent, a parent to the '420 patent, describes a method for matching entities using an auction-based framework. It claims a process of defining data parameters for a first entity (e.g., a caller) and multiple second entities (e.g., agents) and then performing an automated optimization based on "economic surplus" and "opportunity cost" to determine the best match ('086 Patent, Abstract).
  • Asserted Claims: One or more claims, with specifics identified in a non-provided exhibit (Compl. ¶45).
  • Accused Features: Defendant's "Exemplary Defendant Products" are alleged to practice the claimed technology (Compl. ¶45).

III. The Accused Instrumentality

• Product Identification: The complaint does not identify any accused products, methods, or services by name. It refers generally to "Exemplary Defendant Products" that are purportedly identified in claim charts attached as exhibits, which were not provided with the complaint (Compl. ¶15, ¶21, ¶30, ¶39, ¶45).
• Functionality and Market Context: The complaint does not provide sufficient detail for analysis of the functionality or market context of the accused instrumentalities.

IV. Analysis of Infringement Allegations

The complaint alleges that Defendant's "Exemplary Defendant Products" practice the technology claimed by the patents-in-suit (Compl. ¶17, ¶26, ¶35, ¶41, ¶50). However, all specific infringement allegations are deferred to claim chart exhibits (Exhibits 6-10) which were not provided with the filed complaint (Compl. ¶18, ¶27, ¶36, ¶42, ¶51). Therefore, a detailed claim chart summary cannot be constructed.

The narrative infringement theory for the '420 Patent and '748 Patent suggests that Defendant's products implement a form of intelligent or optimized routing. The complaint alleges these products satisfy all elements of the asserted claims by performing functions such as defining parameters for callers and agents and using an optimization or utility-maximization algorithm to route communications between them (Compl. ¶17, ¶26).

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Scope Questions: A central question will be whether the abstract terms used in the patents, such as "auction," "economic surplus," and "aggregate utility," can be construed to read on the specific functionalities of Defendant's products. The scope of these terms will likely be a primary focus of dispute.
  • Technical Questions: A key evidentiary issue will be what proof Plaintiff can offer that Defendant's systems perform the specific "automated optimization" or "utility maximization" required by the claims. The analysis will likely focus on whether the accused systems merely apply a set of static rules or if they perform a dynamic, multi-factorial calculation as described in the patents.

V. Key Claim Terms for Construction

For the ’420 Patent

• The Term: "economic surplus"
• Context and Importance: This term is a cornerstone of independent claim 1 and defines the basis of the claimed optimization. Its construction will be critical to determining whether the accused system performs the claimed function. Practitioners may focus on this term because it is not explicitly defined in the patent and could be subject to multiple interpretations, from a broad business advantage to a narrow, formal economic calculation.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification discusses balancing competing goals in a call center, such as customer service quality and efficient use of resources, suggesting "economic surplus" could encompass non-monetary gains in efficiency or satisfaction ('420 Patent, col. 2:29-34).
  • Evidence for a Narrower Interpretation: The detailed description refers to optimizing "cost-utility function[s]" and mentions economic parameters like "sales volume, profit, or the like," which could support an argument that "economic surplus" requires a quantifiable, financially-based calculation ('420 Patent, col. 24:30-40).

For the ’748 Patent

• The Term: "maximizing an aggregate utility"
• Context and Importance: This phrase from independent claim 1 is the central functional step of the claimed method. The dispute will likely turn on whether the accused system's routing logic constitutes "maximizing" a utility function or simply applying a series of preferences.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification describes a goal of balancing competing factors, which could support a view that any process that systematically weighs multiple variables to achieve a better outcome is "maximizing an aggregate utility" ('748 Patent, col. 2:25-34, from parent '420 Patent).
  • Evidence for a Narrower Interpretation: The specification includes mathematical formulas, such as An=Max(Σ(rsnansn)), which represent a specific method of calculating and maximizing a value ('748 Patent, col. 24:48-52, from parent '420 Patent). A defendant may argue this disclosure limits "maximizing" to a formal mathematical optimization process rather than a general balancing of factors.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for the '748, '979, and '086 Patents. The allegations are based on Defendant allegedly distributing "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, ¶33, ¶48). This inducement theory is premised on knowledge gained from the service of the complaint itself (Compl. ¶25, ¶34, ¶49).
• Willful Infringement: While not pleaded as a separate count, the complaint alleges "Actual Knowledge of Infringement" for the '748, '979, and '086 Patents, stating that service of the complaint and its attached claim charts constitutes such knowledge (Compl. ¶23, ¶32, ¶47). This forms a basis for a potential claim of post-filing willful infringement.

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

• A core issue will be one of evidentiary sufficiency: As the complaint defers all technical details of infringement to non-provided exhibits, a central question will be what evidence Plaintiff can marshall to demonstrate that Defendant's unidentified products actually perform the complex optimization and matching functions recited in the claims.
• A second key issue will be one of definitional scope: The case will likely hinge on the construction of abstract, functional claim terms such as "auction," "economic surplus," and "maximizing an aggregate utility." The ability of Plaintiff to prove these terms read on the technical operation of Defendant's systems, or Defendant's ability to distinguish them, will be critical to the outcome.
• A third question concerns the basis for indirect and willful infringement: Since the allegations of knowledge and intent for inducement and potential willfulness are based entirely on the filing of the lawsuit itself, a key legal question will be whether Defendant’s post-filing conduct rises to the level required to prove these claims, particularly if there are substantial non-infringement or invalidity defenses.
