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.

The Invention Explained

• Problem Addressed: The patent's background describes the challenge of efficiently managing call centers, where the goal is to balance high-quality customer service with the efficient use of resources like human agents (US10237420B1, col. 2:25-34). Traditional methods, such as first-come-first-served or simple skill-based routing, are often suboptimal (US 10,237,420 B1, col. 4:13-34).
• The Patented Solution: The invention proposes a system that treats the matching of a "first entity" (like a caller) to a "second entity" (like an agent) as an auction (US 10,237,420 B1, Abstract). It uses data representing the entities' parameters to perform an "automated optimization" that considers not only the quality of the match but also its "economic surplus" and the "opportunity cost" of making an agent unavailable for other potential matches (US 10,237,420 B1, Abstract; Fig. 7).
• Technical Importance: This approach introduces economic modeling concepts into telecommunications routing, aiming for a more globally optimal resource allocation than was possible with prior art rule-based systems (US 10,237,420 B1, col. 22:1-24).

Key Claims at a Glance

• The complaint asserts unspecified "exemplary method claims" (Compl. ¶15). Independent claim 1 is representative.
• Essential elements of claim 1 include:
  • 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 entity and one of the second entities.
  • The optimization also considers an opportunity cost related to the unavailability of the matched second entity for an alternate first entity.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

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

• Issued: November 26, 2019.

The Invention Explained

• Problem Addressed: Similar to the ’420 Patent, this patent addresses the inefficiencies in traditional call center routing systems, which struggle to balance competing goals like service quality and resource utilization (US10491748B1, col. 2:25-34, via parent patent).
• The Patented Solution: The invention is a communications routing system that uses predicted characteristics of both "communications sources" and "communications targets," with each having an associated "economic utility" (US 10,491,748 B1, Abstract). The system determines an optimal routing by "maximizing an aggregate utility" across all potential source-target linkages, moving beyond simple one-to-one matching to a system-wide optimization (US 10,491,748 B1, Abstract; col. 24:40-50).
• Technical Importance: This patent claims a method for intelligent routing based on maximizing a global utility function, providing a framework for making complex, multi-variable routing decisions in real-time (US 10,491,748 B1, col. 25:10-26:2).

Key Claims at a Glance

• The complaint asserts unspecified "exemplary claims" (Compl. ¶21). Independent claim 1 is representative.
• Essential elements of claim 1 include:
  • Representing predicted characteristics and an economic utility for a plurality of communications sources.
  • Representing predicted characteristics and an economic utility for a plurality of communications targets.
  • Determining an optimal routing between sources and targets by maximizing an aggregate utility with respect to their predicted characteristics.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

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

• Issued: April 4, 2006 (Compl. ¶11).
• Technology Synopsis: This patent describes a system for intelligent call routing in a telephony control system.

• Technology Synopsis: This patent discloses a method for matching entities by treating the process as an auction. It describes defining parameters for a first entity (e.g., a caller) and multiple second entities (e.g., agents) and then performing an automated optimization based on the economic surplus of a match and the opportunity cost of making a resource unavailable for other potential matches (US9456086B1, Abstract).
• Asserted Claims: The complaint asserts "one or more claims" without specifying them (Compl. ¶42).
• Accused Features: The complaint alleges that unspecified "Exemplary Defendant Products" infringe the patent (Compl. ¶42).

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any specific accused products, services, or methods by name (Compl. ¶¶15, 21, 30, 36, 42). It refers generally to "Exemplary Defendant Products" that are purportedly detailed in claim chart exhibits.

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of functionality or market context. It alleges infringement through Defendant's acts of "making, using, offering to sell, selling and/or importing" the accused products and through internal testing by employees (Compl. ¶¶15-16, 21-22). The complaint incorporates by reference Exhibits 6-10, which allegedly contain claim charts comparing the asserted patents to the accused products, but these exhibits were not filed with the complaint (Compl. ¶¶17, 26, 32, 38, 47). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references claim-chart exhibits that are not provided. It alleges that these exhibits demonstrate that the "Exemplary Defendant Products" practice the technology claimed by the patents-in-suit and satisfy all claim elements (Compl. ¶¶17, 26, 32, 38, 47). However, without the exhibits, the complaint lacks specific factual allegations detailing how any feature of an accused product maps to any specific limitation of an asserted claim. The infringement theory appears to be that Defendant's systems, in routing communications or transactions, perform the type of economic or utility-based optimization claimed in the patents.

• Identified Points of Contention:
  • Evidentiary Questions: The central issue will be what evidence Plaintiff can produce to demonstrate that Defendant's systems perform the specific functions required by the claims. For the ’420 and ’086 Patents, this raises the question of whether Defendant's systems perform an "automated optimization" that calculates both an "economic surplus" and an "opportunity cost."
  • Scope Questions: For the ’748 Patent, a key question will be whether any optimization performed by Defendant's systems can be characterized as "maximizing an aggregate utility" as defined by the patent. For the '979 and '253 patents, a point of contention may be whether Defendant's systems constitute a "telephony control system" that performs "intelligent call routing" within the scope of the claims.

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 term is the functional heart of claim 1. Its construction will be critical because infringement will depend on whether the accused system's resource allocation algorithm performs this specific two-part economic calculation. Practitioners may focus on this term because Defendant will likely argue that its system considers factors different from, or less complex than, a formal "economic surplus" and "opportunity cost."

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification describes the goal of balancing competing goals, such as providing high-quality service while making efficient use of call center resources, which may support a broader interpretation of what constitutes an economic optimization (US 10,237,420 B1, col. 2:25-34).
  • Evidence for a Narrower Interpretation: The detailed description explains these concepts in the context of specific call-center scenarios and optimization formulas, which could support a narrower definition tied to those embodiments (US 10,237,420 B1, col. 23:42-24:50).

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

• Context and Importance: This term defines the core optimization function of the claimed routing method. The outcome of the case may turn on whether the accused system's process for selecting a routing path meets the specific definition of "maximizing an aggregate utility." Practitioners may focus on this term because the dispute will likely center on the technical question of whether Defendant's system performs a global optimization across all sources and targets, or a series of simpler, local optimizations.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The abstract's general description of determining an "optimal routing" between sources and targets could support a broad interpretation covering various forms of optimization (US 10,491,748 B1, Abstract).
  • Evidence for a Narrower Interpretation: The patent specification provides specific formulas for calculating utility, such as An=Max({[Acn1∑(rs1ans1)+Acn2]+Bcn}+Ccn)+Dcn), which includes factors for agent cost, anticipated value, and opportunity cost (US 10,491,748 B1, col. 24:51-62, via parent). This detailed formula may support a narrower construction limited to systems that consider these specific inputs.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for the ’748 Patent and the ’086 Patent. The allegations are based on Defendant distributing "product literature and website materials" that allegedly instruct end users to use the accused products in an infringing manner (Compl. ¶¶24, 45). Knowledge and intent are alleged to exist at least since the service of the complaint (Compl. ¶¶25, 46).
• Willful Infringement: The complaint does not use the term "willful." However, it alleges that Defendant has had "actual knowledge" of the ’748 and ’086 Patents since being served with the complaint and has "actively, knowingly, and intentionally continued to induce infringement" (Compl. ¶¶23, 25, 44, 46). These allegations could form the basis for a claim of post-suit willful infringement and a request for enhanced damages.

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

1. A central issue will be one of evidentiary sufficiency: Given that the complaint defers all specific infringement allegations to unfiled exhibits, a key question is what factual evidence Plaintiff will present to show that Defendant's systems actually perform the complex, multi-part economic and utility-based optimizations required by the asserted claims.
2. A key legal question will be one of definitional scope: Can terms rooted in economic and call-center theory, such as "economic surplus," "opportunity cost," and "maximizing an aggregate utility," be construed to cover the algorithms used in Defendant's modern electronic systems, or is there a fundamental mismatch in technical operation and scope?
3. A secondary issue will concern indirect infringement: For the inducement claims, the case may explore whether Defendant's standard product literature and website materials contain the specific instructions and show the requisite intent to encourage infringement of the claimed methods.
