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"

• Patent Identification: U.S. Patent No. 10,237,420, "Method and system for matching entities in an auction," issued March 19, 2019 (Compl. ¶9).

The Invention Explained

• Problem Addressed: The patent addresses inefficiencies in traditional call center management, where routing incoming calls based on simple rules (e.g., first-in, first-out) can lead to mismatches between a caller's needs and an agent's skills, creating problems with "under-skilled" or "over-skilled" agents and reducing overall throughput (’420 Patent, col. 3:35-4:64).
• The Patented Solution: The invention proposes a method for matching a "first entity" (e.g., a caller) with an optimal "second entity" (e.g., a service agent) from a pool of available options. Instead of static rules, the method performs an "automated optimization" based on economic principles, considering the "economic surplus" of a potential match as well as the "opportunity cost" of making that agent unavailable for other potential communications (’420 Patent, Abstract; Fig. 1). This is achieved by defining "inferential targeting parameters" for the caller and "characteristic parameters" for the agents and using a cost-utility function to determine the best pairing (’420 Patent, col. 23:41-24:8).
• Technical Importance: The technology represents a shift from static, queue-based call distribution to a dynamic, economic optimization model, enabling more flexible and efficient resource allocation in large-scale communication systems (’420 Patent, col. 18:9-24).

Key Claims at a Glance

• The complaint alleges infringement of one or more claims of the ’420 Patent, referring to charts in an external exhibit to identify exemplary claims (Compl. ¶15, ¶17). An analysis of representative independent claim 1 is presented below.
• The essential elements of independent claim 1 include:
  • A method for matching a first entity with at least one second entity selected from a plurality of second entities;
  • 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 the plurality of second entities; and
  • performing an automated optimization with respect to an economic surplus of a respective match and 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 in its narrative text, though this is standard litigation practice.

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 (Compl. ¶10).

The Invention Explained

• Problem Addressed: The complaint does not provide specific details from the ’748 Patent’s specification, but the patent family and claims suggest it addresses the same technical problem as the ’420 Patent: the inefficient routing of communications in systems like call centers (’420 Patent, col. 1:26-2:67).
• The Patented Solution: The invention is a communications routing system that determines an optimal routing path by modeling both communication "sources" (e.g., callers) and "targets" (e.g., agents) based on their predicted characteristics and an associated "economic utility." The system then works to maximize the "aggregate utility" of all matches between the sources and targets (’748 Patent, Abstract). This approach frames the technical problem of routing as an economic optimization problem.
• Technical Importance: The system provides a framework for intelligent, utility-maximizing resource allocation in complex communication networks, moving beyond simple, sequential routing rules (’748 Patent, Abstract).

Key Claims at a Glance

• The complaint alleges infringement of one or more claims of the ’748 Patent, referring to charts in an external exhibit to identify exemplary claims (Compl. ¶21, ¶26). An analysis of representative independent claim 1 is presented below.
• The essential elements of independent claim 1 include:
  • A communications routing system comprising a processor and a non-transitory computer readable medium;
  • representing a plurality of predicted characteristics of communications sources, each having an economic utility;
  • representing a plurality of predicted characteristics 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 predicted characteristics.
• The complaint does not explicitly reserve the right to assert dependent claims in its narrative text.

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

• Patent Identification: U.S. Patent No. 7,023,979, "Telephony control system with intelligent call routing," issued April 4, 2006 (Compl. ¶11).
• Technology Synopsis: Based on its title and early priority date, this patent appears to disclose foundational concepts for the intelligent call routing technology asserted in the litigation. It likely addresses the problem of matching callers to appropriate agents in a telephony system using criteria beyond simple queuing.
• Asserted Claims: The complaint refers to "exemplary claims" identified in an external chart exhibit (Compl. ¶30, ¶32).
• Accused Features: The complaint alleges that "Exemplary Defendant Products" practice the technology claimed by the ’979 Patent (Compl. ¶30, ¶32).

• Patent Identification: U.S. Patent No. 9,456,086, "Method and system for matching entities in an auction," issued September 27, 2016 (Compl. ¶13).
• Technology Synopsis: This patent’s title suggests it is a direct predecessor to the ’420 Patent. It addresses the technical problem of resource allocation by framing the matching of entities as an auction, allowing for dynamic, value-based pairing of communications sources and targets.
• Asserted Claims: The complaint refers to "exemplary claims" identified in an external chart exhibit (Compl. ¶42, ¶47).
• Accused Features: The complaint alleges that "Exemplary Defendant Products" practice the technology claimed by the ’086 Patent (Compl. ¶42, ¶47).

III. The Accused Instrumentality

Product Identification

• The complaint identifies the accused instrumentalities as "Exemplary Defendant Products" (Compl. ¶15). It further states that these products are identified in charts incorporated by reference as Exhibits 6 through 10 (Compl. ¶17, ¶26, ¶32, ¶38, ¶47).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the accused products' specific functionality, operation, or market context. The allegations are conclusory, stating only that the accused products "practice the technology claimed" by the patents-in-suit (Compl. ¶17, ¶26). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint incorporates by reference external claim chart exhibits (Exhibits 6-10) that allegedly compare the asserted patent claims to the accused products (Compl. ¶17-18, ¶26-27, ¶32-33, ¶38-39, ¶47-48). However, these exhibits are not attached to the complaint document, and the complaint body provides no narrative summary of the infringement theories. A detailed infringement analysis is therefore not possible based on the provided document.

• Identified Points of Contention:
  • Technical Questions: A central technical question for all asserted patents will be whether Defendant's systems perform the specific optimization and economic modeling functions required by the claims. For instance, with respect to the ’420 and ’086 Patents, what evidence does the complaint provide that the accused products conduct an "auction" or calculate an "economic surplus" and "opportunity cost" to match entities?
  • Scope Questions: The infringement analysis for the ’748 Patent raises the question of whether the accused system’s routing logic can be said to "maximize an aggregate utility." This will likely involve a dispute over whether a general-purpose performance-enhancement algorithm meets the specific functional language of the claim.

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 phrase captures the core inventive concept of the method claim. The outcome of the infringement analysis for the auction-based patents will likely depend on whether the accused system's functionality falls within the court's construction of this term. Practitioners may focus on this term because it appears to require a specific, multi-faceted economic calculation rather than a generic efficiency algorithm.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification discusses converting non-economic goals like "customer satisfaction" into "economic terms" for use in an optimization, suggesting that "economic surplus" could be construed broadly to encompass general business utility rather than literal monetary profit (’420 Patent, col. 24:36-40).
  • Evidence for a Narrower Interpretation: The specification discloses a specific multi-part formula for an "optimization" that includes distinct terms for agent cost, anticipated change in agent value, transaction value, and opportunity cost, which may support a narrower construction requiring a similarly complex calculation (’420 Patent, col. 24:50-65).
• The Term: "maximizing an aggregate utility" (from ’748 Patent, claim 1)
• Context and Importance: This is the central function of the claimed system. Infringement will depend on whether the accused system is shown to perform this specific utility-maximization function for a plurality of sources and targets, rather than simply routing communications based on a different logic.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The related ’420 Patent specification, which provides context for the technology family, describes optimizing a "cost-utility function" that considers factors like agent productivity and training needs, suggesting "utility" could be interpreted broadly to cover various performance and operational goals (’420 Patent, Fig. 1; col. 23:41-24:8).
  • Evidence for a Narrower Interpretation: A defendant may argue that "maximizing an aggregate utility" requires a specific, global optimization across all pending communications, as opposed to a series of localized or sequential optimizations. The specification’s discussion of selecting an "optimal pairing of respective multiple agents with multiple matters" could support this narrower view (’420 Patent, col. 24:62-65).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the ’748 and ’086 Patents. The allegations state that Defendant distributes "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 does not use the term "willful." However, it alleges "Actual Knowledge of Infringement" for the ’748 and ’086 Patents, based on the service of the Original Complaint and its associated claim charts (Compl. ¶23, ¶44). It further alleges that Defendant's infringement continued despite this knowledge, which may form the basis for a claim of post-suit willfulness (Compl. ¶24, ¶45).

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

• A core issue will be one of technical and functional correspondence: can Plaintiff demonstrate that the algorithms in Defendant’s accused systems perform the specific economic and utility-based optimizations recited in the claims? The case will likely turn on whether generic efficiency-seeking logic can be mapped onto claim limitations requiring the calculation of "economic surplus," "opportunity cost," and the maximization of "aggregate utility."
• A key procedural question will be one of pleading sufficiency: the complaint makes only conclusory allegations of infringement in its narrative body, relying entirely on external exhibits that are not part of the pleading itself. This raises the question of whether the complaint provides sufficient factual detail to state a plausible claim for relief under the standards set by Twombly and Iqbal.
• A central evidentiary question will be one of proof: given the internal and proprietary nature of the accused routing systems, the case will depend on what evidence Plaintiff can obtain through discovery to show that the systems actually operate in the manner required by the patent claims.
