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

The Invention Explained

• Problem Addressed: The patent's background describes the inefficiency of traditional call center management, where calls are routed by simple rules like first-come-first-served or to the longest-idle agent ('420 Patent, col. 3:1-19). These methods fail to account for the specific skills of agents or the unique needs of callers, leading to problems like routing calls to under-skilled or over-skilled agents, which reduces transactional throughput ('420 Patent, col. 4:35-64).
• The Patented Solution: The invention proposes a system that treats the matching of a caller to an agent as an "auction" ('420 Patent, Abstract). It defines "multivalued scalar data" representing the caller's needs ("inferential targeting parameters") and the agent's capabilities ("characteristic parameters") ('420 Patent, Abstract). The system then performs an "automated optimization" to find the best match, considering not just skill correspondence but also the "economic surplus" of a good match and the "opportunity cost" of making a skilled agent unavailable for a future, potentially more valuable, call ('420 Patent, Abstract; Fig. 1). This allows for a more dynamic and economically efficient routing decision that can also factor in long-term goals like agent training ('420 Patent, col. 24:28-40).
• Technical Importance: The invention moves beyond static, rule-based call distribution to a dynamic, holistic optimization model that can balance immediate efficiency with long-term strategic objectives in a resource-constrained environment ('420 Patent, col. 5:10-14).

Key Claims at a Glance

• The complaint alleges infringement of one or more claims, but does not specify which ones (Compl. ¶15). Claim 1 is the first independent claim.
• Essential elements of Claim 1 include:
  • 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 representing characteristic parameters for each of a plurality of second entities.
  • 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 at least one second entity 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"

• Issued: November 26, 2019

The Invention Explained

• Problem Addressed: This patent addresses the same technical problem as the ’420 Patent: the limitations of traditional, non-adaptive call routing systems that do not intelligently match communications to agents based on a holistic view of skills and economic factors (’748 Patent, col. 1:12-2:67).
• The Patented solution: The invention describes a communications routing system that represents communications sources (e.g., callers) and targets (e.g., agents) with "predicted characteristics," each having an "economic utility" (’748 Patent, Abstract). The system determines an optimal routing path between sources and targets by "maximizing an aggregate utility" (’748 Patent, Abstract). This approach, similar to the '420 Patent, uses a cost-utility function that can incorporate long-term objectives like agent training alongside short-term efficiency, particularly when a call center is not operating at peak capacity (’748 Patent, Fig. 1; col. 35:30-36:1).
• Technical Importance: The technology provides a framework for intelligent, utility-maximizing routing that can be adapted for different operational conditions, such as prioritizing training during low-demand periods and prioritizing throughput during high-demand periods (’748 Patent, col. 36:4-10).

Key Claims at a Glance

• The complaint asserts one or more claims without specifying them (Compl. ¶21). Claim 1 is the first independent claim.
• Essential elements of Claim 1 include:
  • A communications routing method.
  • Representing predicted characteristics of a plurality of communications sources, each having an economic utility.
  • Representing 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 the predicted characteristics.
• The complaint does not explicitly reserve the right to assert dependent claims.

Multi-Patent Capsule Analysis

• U.S. Patent No. 7,023,979, "Telephony control system with intelligent call routing," issued April 4, 2006.

  • Technology Synopsis: This patent describes a communications management system that uses a database of skill weights and agent skill scores to compute an optimal agent selection for an incoming communication. The system directly controls the routing of the communication based on this computation ('979 Patent, Abstract).
  • Asserted Claims: One or more unspecified claims (Compl. ¶30).
  • Accused Features: The complaint alleges that the "Exemplary Defendant Products" practice the technology claimed by the '979 patent, as detailed in the non-proffered Exhibit 8 (Compl. ¶¶30, 32).

• U.S. Patent No. 7,269,253, "Telephony control system with intelligent call routing," issued September 11, 2007.

  • Technology Synopsis: This patent discloses a system and method where communications are received with associated classification information. An optimal target for the communication is determined through a combinatorial optimization that considers the characteristics of at least three potential targets ('253 Patent, Abstract).
  • Asserted Claims: One or more unspecified claims (Compl. ¶36).
  • Accused Features: The complaint alleges that the "Exemplary Defendant Products" practice the technology claimed by the '253 patent, as detailed in the non-proffered Exhibit 9 (Compl. ¶¶36, 38).

• U.S. Patent No. 9,456,086, "Method and system for matching entities in an auction," issued September 27, 2016.

  • Technology Synopsis: This patent describes a method for matching entities by defining targeting parameters for a first entity (e.g., a caller) and characteristic parameters for multiple second entities (e.g., agents). An automated optimization is performed to select a match based on the "economic surplus" of the match and the "opportunity cost" of making a particular second entity unavailable for a future match ('086 Patent, Abstract).
  • Asserted Claims: One or more unspecified claims (Compl. ¶42).
  • Accused Features: The complaint alleges that the "Exemplary Defendant Products" practice the technology claimed by the '086 patent, as detailed in the non-proffered Exhibit 10 (Compl. ¶¶42, 47).

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any specific accused product, method, or service by name. It refers generally to "Exemplary Defendant Products" that are purportedly detailed in claim charts attached as Exhibits 6-10, which were not filed with the complaint (Compl. ¶¶15, 17, 21, 26, 30, 32, 36, 38, 42, 47).

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 references claim-chart exhibits that are not provided (Compl. ¶¶17-18, 26-27, 32-33, 38-39, 47-48). Therefore, the specific infringement allegations cannot be analyzed in a chart format.

The narrative infringement theory for the ’420 Patent is that Defendant directly infringes by making, using, selling, and/or importing unidentified "Exemplary Defendant Products" (Compl. ¶15). The complaint further alleges that Defendant's employees directly infringe by internally testing and using these products (Compl. ¶16). The complaint asserts that these products "practice the technology claimed by the '420 Patent" and "satisfy all elements of the Exemplary '420 Patent Claims" (Compl. ¶17).

The narrative infringement theory for the ’748 Patent is similar, alleging direct infringement through making, using, and selling the products, as well as through internal testing by employees (Compl. ¶¶21-22). The complaint states that these products "practice the technology claimed by the '748 Patent" and "satisfy all elements of the Exemplary '748 Patent Claims" (Compl. ¶26).

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail to identify specific points of contention regarding claim term construction. However, based on the technology, certain terms from the independent claims of the lead patents may become central to the dispute.

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

• Context and Importance: This term is at the core of the patent's optimization function. The dispute may turn on whether the accused system's matching or routing calculation qualifies as an optimization with respect to an "economic surplus." Practitioners may focus on whether this term requires a calculation tied to actual monetary value or if it can be construed more broadly to cover abstract utility or efficiency scores.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification discusses optimizing for non-monetary business goals, such as customer satisfaction, and notes that these must be "converted and normalized into economic terms prior to use in an optimization," suggesting the term may encompass abstract, normalized values ('420 Patent, col. 24:36-40). The inclusion of "training and reward/punishment" in the cost function also suggests a broader, non-monetary scope ('420 Patent, col. 24:1-3).
  • Evidence for a Narrower Interpretation: The use of the word "economic" itself, along with descriptions of optimizing based on factors like "sales volume, profit, or the like," could support an argument that the term requires a connection to tangible financial metrics ('420 Patent, col. 24:32-35).

• The Term: "inferential targeting parameters" (’420 Patent, Claim 1)

• Context and Importance: The infringement analysis will depend on whether the data used by the accused system to characterize a communication (the "first entity") meets the definition of "inferential targeting parameters." The question may be whether this requires a specific type of predictive or analytical data processing, or if it can read on simpler classification data.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent suggests these parameters can be derived from basic information like the dialed number, calling number, or caller responses to prompts, which could support a reading on simpler data points ('420 Patent, col. 4:36-40).
  • Evidence for a Narrower Interpretation: The term "inferential" suggests a process of deduction or reasoning rather than direct measurement. The specification's discussion of characterizing the caller through "voice stress analysis, word cadence, accent, sex... [and] personality type" supports a narrower construction requiring more complex, derived data points ('420 Patent, col. 23:6-10).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the ’748 and ’086 Patents (Compl. ¶¶25, 46). The allegations are based on Defendant selling its products to customers and 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, 45).
• Willful Infringement: The complaint alleges "Actual Knowledge of Infringement" for the ’748 and ’086 Patents (Compl. ¶¶23, 44). However, this knowledge is explicitly based on "The service of this Complaint," suggesting the allegations are limited to post-suit conduct and would not support a claim for pre-suit willful infringement.

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

1. A primary issue will be one of applicability: how does the patented technology, described in the context of call centers and communication routing, apply to the specific, unidentified "Exemplary Defendant Products" of American Axle & Manufacturing, an automotive supplier? The viability of the infringement claims will depend on the nature of the accused products and whether the patent claims can be construed to cover functionalities outside of the call-center domain.
2. A key evidentiary question will be one of factual support: given that the complaint's technical infringement allegations are made entirely by incorporation of non-proffered exhibits, a central issue will be whether the plaintiff can produce sufficient evidence to show that the accused products actually perform the specific multi-step optimization and data representation methods required by the asserted claims.
3. A central question of claim scope may be definitional: can terms like "economic surplus" and "auction," which are rooted in financial and transactional contexts, be construed to cover the technical operations of the accused products, particularly if those operations relate to non-transactional processes like manufacturing or logistics management?
