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 addresses inefficiencies in call centers, such as routing calls to under-skilled or over-skilled agents, which reduces transactional throughput (’420 Patent, col. 4:35-62). Traditional systems often rely on simple "first-in, first-out" queues or static agent groupings, which fail to adapt to changing call types and agent availability (’420 Patent, col. 3:22-34).
• The Patented Solution: The invention proposes a method for matching a "first entity" (e.g., an incoming call) with an optimal "second entity" (e.g., a call center agent) from a pool of available agents (’420 Patent, col. 1:58-62). This is achieved through an "automated optimization" that considers not only the characteristics of the caller and the skills of the agent, but also economic factors like the "economic surplus" of a good match and the "opportunity cost" of making an agent unavailable for other potential matches (’420 Patent, Abstract). The system treats the matching process as a type of auction to determine the best pairing (’420 Patent, col. 11:53-62).
• Technical Importance: The technology aims to move beyond simple skill-based routing by incorporating economic modeling and optimization to manage call center resources more dynamically and efficiently (’420 Patent, col. 4:5-9).

Key Claims at a Glance

• The complaint incorporates by reference charts that identify "Exemplary '420 Patent Claims" but does not specify them in the body of the complaint (Compl. ¶15, 17). Claim 1 is the first independent claim.
• Essential elements of Claim 1 include:
  • defining multivalued scalar data representing inferential targeting parameters for a first entity;
  • defining 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; and
  • performing the optimization with respect to 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.

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

• Issued: November 26, 2019

The Invention Explained

• Problem Addressed: The patent identifies the same general problem as the '420 Patent: the need for more intelligent routing in telecommunications systems like call centers to improve efficiency and customer satisfaction (’748 Patent, col. 2:25-34).
• The Patented Solution: The invention describes a system that routes communications by predicting characteristics of both the communication source (e.g., a caller) and the target (e.g., an agent), and then determining an optimal routing that maximizes an "aggregate utility" (’748 Patent, Abstract). The system uses a "cost-utility function" that can incorporate factors like long-term call center operational goals, including agent training, rather than just immediate efficiency (’748 Patent, col. 6:30-36; Fig. 1).
• Technical Importance: The described solution allows for routing decisions to be based on a holistic, long-term view of a call center's objectives, including balancing immediate throughput with strategic goals like workforce development (’748 Patent, col. 27:10-16).

Key Claims at a Glance

• The complaint incorporates by reference charts that identify "Exemplary '748 Patent Claims" but does not specify them in the body of the complaint (Compl. ¶21, 26). Claim 1 is the first independent claim.
• Essential elements of Claim 1 include:
  • representing predicted characteristics of communications sources, each having an economic utility;
  • representing 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.

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

• Issued: April 4, 2006
• Technology Synopsis: The patent describes a telephony control system that uses a "cost-utility function" to optimize call routing. The system considers both the characteristics of the incoming call and the skills of available agents to determine an optimal match, with the goal of improving call center efficiency beyond simple queue-based methods (’979 Patent, col. 18:40-49).
• Asserted Claims: The complaint refers to "Exemplary '979 Patent Claims" in an external exhibit (Compl. ¶30, 35).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in charts incorporated by reference as Exhibit 8 (Compl. ¶30, 35).

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

• Issued: September 11, 2007
• Technology Synopsis: This patent, related to the ’979 Patent, discloses a system for intelligent call routing based on a "combinatorial optimization" of available agents and incoming calls. The system aims to find the best agent for a call by analyzing various characteristics of both, thereby improving upon traditional call distribution methods (’253 Patent, col. 40:1-10).
• Asserted Claims: The complaint refers to "Exemplary '253 Patent Claims" in an external exhibit (Compl. ¶39, 41).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in charts incorporated by reference as Exhibit 9 (Compl. ¶39, 41).

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

• Issued: September 27, 2016
• Technology Synopsis: Related to the ’420 Patent, this invention describes a method for matching entities by conducting a form of auction. It defines parameters for a first entity (e.g., a call) and characteristic parameters for a plurality of second entities (e.g., agents) and performs an optimization based on economic surplus and opportunity cost to determine the best match (’086 Patent, Abstract).
• Asserted Claims: The complaint refers to "Exemplary '086 Patent Claims" in an external exhibit (Compl. ¶45, 50).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in charts incorporated by reference as Exhibit 10 (Compl. ¶45, 50).

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any accused products, methods, or services by name (Compl. ¶15, 21, 30, 39, 45). It refers generally to "Exemplary Defendant Products" that are identified in external Exhibits 6, 7, 8, 9, and 10, which are incorporated by reference but not attached to the publicly filed complaint (Compl. ¶17, 26, 35, 41, 50).

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

No probative visual evidence provided in complaint.

The complaint's infringement allegations for all five patents-in-suit are made exclusively through reference to external claim chart exhibits that were not provided with the complaint (Compl. ¶17-18, 26-27, 35-36, 41-42, 50-51). The complaint asserts that these charts demonstrate that the "Exemplary Defendant Products" practice the claimed technology and satisfy all elements of the asserted claims (Compl. ¶17, 26, 35, 41, 50). However, because the complaint provides no narrative infringement theory in its body, there is insufficient detail for a substantive analysis of the infringement allegations or for the construction of a claim chart summary.

• Identified Points of Contention:
  • Scope Questions: A central question for the '420 and '086 Patents will be whether Defendant's system for managing customer communications performs an "auction" as that term is used in the claims. The analysis may explore whether a system that optimizes routing based on agent availability and skills, without a formal bidding mechanism, can be construed as conducting an "auction."
  • Technical Questions: For all asserted patents, a key point of contention may be whether Defendant's system performs the specific "automated optimization" or calculates a "cost-utility function" as required by the claims. The dispute may focus on whether the accused system's routing logic meets the specific mathematical and economic parameters recited, such as "economic surplus" and "opportunity cost" (’420 Patent, Claim 1), or if it employs a more generalized, heuristic-based routing method.

V. Key Claim Terms for Construction

The Term: "auction" (from the '420 and '086 Patents)

• Context and Importance: This term is central to the infringement theory for two of the five patents. The defendant, an insurance company, likely operates a customer service or sales call center. Whether its system for assigning customer inquiries to agents can be characterized as conducting an "auction" will be a critical issue.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification discusses the "auction" in the context of routing communications based on both "economic factors and non-economic factors," which could suggest the term is not limited to traditional monetary bidding but could encompass any competitive allocation based on optimizing value (’420 Patent, col. 11:42-45).
  • Evidence for a Narrower Interpretation: The specification also refers to auction types such as "Dutch-type auctions" and "English-type (progressive) auctions," which are well-understood terms of art involving explicit price adjustments and bidding (’420 Patent, col. 13:26-31). This may support a narrower construction limited to systems with formal bidding mechanisms.

The Term: "cost-utility function" (from the '748, '979, and '253 Patents)

• Context and Importance: This term appears in the claims of three asserted patents and is foundational to the patented solution for intelligent routing. Practitioners may focus on this term because its definition will determine whether a standard rules-based routing engine infringes, or if the claims are limited to systems that perform a specific, multi-factor quantitative analysis.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent describes the function in broad terms as balancing competing goals to make "efficient use of call center resources" (’748 Patent, col. 2:32-34). This could support a reading that covers any logic system that weighs different factors to achieve an efficient outcome.
  • Evidence for a Narrower Interpretation: The specification provides a specific mathematical formula for the "cost-utility function," which includes terms for agent cost, anticipated change in agent value, anticipated transaction value, and opportunity cost (’748 Patent, col. 24:52-57). This explicit definition could be used to argue for a narrower construction requiring a system that calculates these specific, or equivalent, quantitative variables.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for the ’748, ’979, 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, 33, 48).
• Willful Infringement: The complaint alleges that service of the complaint itself provides Defendant with "actual knowledge of infringement" for the ’748, ’979, and ’086 Patents (Compl. ¶23, 32, 47). This forms the basis for potential claims of willful infringement for any infringing conduct occurring after the date the complaint was filed.

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

• A core issue will be one of definitional scope: can the term “auction,” as used in the ’420 and ’086 Patents, be construed to cover a system that optimizes the assignment of customer inquiries to agents without a formal, price-based bidding mechanism? The resolution of this question may determine whether a significant portion of the plaintiff's case is viable.
• A second central question will be one of functional operation: do the accused systems, presumably call center management software, perform the specific multi-factor "automated optimization" and "cost-utility function" calculations required by the claims, or do they operate on a different technical principle, such as a simpler, rules-based logic?
• A key evidentiary and procedural question will be whether the complaint, which makes its infringement allegations entirely by reference to unattached exhibits, provides sufficient notice of the basis for the lawsuit. This raises the question of how Plaintiff will substantiate its claims that Defendant’s unspecified products meet each limitation of the asserted claims.
