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

The Invention Explained

• Problem Addressed: The patent's background describes the inefficiencies of traditional call centers that use simple, first-come-first-served or longest-idle-agent routing logic (U.S. Patent No. 10,237,420, col. 2:45-3:12). These systems often fail to account for agent skill levels or the specific needs of a caller, leading to problems such as routing calls to under-skilled or over-skilled agents, which reduces transactional throughput and customer satisfaction (’420 Patent, col. 4:35-62).
• The Patented Solution: The invention proposes a system that treats the matching of a "first entity" (e.g., a caller) with a "second entity" (e.g., an agent) as a dynamic optimization or auction (’420 Patent, Abstract). Instead of static rules, the system defines "inferential targeting parameters" for the caller and "characteristic parameters" for the agents and performs an "automated optimization" that considers the "economic surplus" of a potential match and the "opportunity cost" of making an agent unavailable for other potential matches (’420 Patent, col. 20:9-24). This process is depicted in the flowchart of Figure 1, which shows parallel logic paths for optimizing call routing based on different criteria, such as call center capacity (’420 Patent, Fig. 1).
• Technical Importance: This approach sought to improve call center efficiency by applying economic and game-theory principles to a telecommunications problem, creating a more dynamic and globally optimized routing system than was available in conventional Automatic Call Distributor (ACD) systems (’420 Patent, col. 1:49-2:24).

Key Claims at a Glance

• The complaint asserts "one or more claims" and "exemplary method claims" without specifying claim numbers (Compl. ¶15). Independent claim 1 is a representative method claim.
• Independent Claim 1:
  • A method for matching a first entity with at least one second entity selected from a plurality of second entities, comprising:
  • defining a plurality of multivalued scalar data representing inferential targeting parameters for the first entity and a plurality of multivalued scalar data of each of the plurality of second entities, representing respective characteristic parameters for each respective second entity; and
  • performing an automated optimization with respect to an economic surplus of a respective match of the first entity with the at least one of the plurality of second entities, 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 but refers generally to "one or more claims" (Compl. ¶15).

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

The Invention Explained

• Problem Addressed: The ’748 Patent addresses the same technical problem as the ’420 Patent: the inefficiency of traditional call center routing systems that do not dynamically optimize the matching of communications to agents based on a holistic view of the system's needs and goals (’748 Patent, col. 1:49-2:24).
• The Patented Solution: The invention is a communications routing system that represents both communication sources (e.g., callers) and communication targets (e.g., agents) by their "predicted characteristics" and an associated "economic utility" (’748 Patent, Abstract). The system then determines an "optimal routing" by "maximizing an aggregate utility" for all potential linkages, thereby moving beyond simple one-to-one matching to a global optimization of the entire system's performance (’748 Patent, col. 23:23-24:67).
• Technical Importance: The technology aimed to provide a more sophisticated, utility-based framework for call routing that could account for long-term business goals, such as agent training and customer satisfaction, rather than just short-term metrics like call duration (’748 Patent, col. 27:8-28:41).

Key Claims at a Glance

• The complaint asserts "one or more claims" without specifying claim numbers (Compl. ¶21). Independent claim 1 is a representative system claim.
• Independent Claim 1:
  • A communications routing system, comprising:
  • a memory storing a plurality of predicted characteristics of a plurality of communications sources, each having an economic utility, and a plurality of predicted characteristics of a plurality of communications targets, each having an economic utility; and
  • a processor, configured to determine an optimal routing between the plurality of communications sources and the plurality of communications targets, by maximizing an aggregate utility with respect to the respective predicted characteristics of communications source and communications destination represented by linkages.
• The complaint does not explicitly reserve the right to assert dependent claims (Compl. ¶21).

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 for intelligent call routing. It discloses a system that receives a communication classification, accesses a database of agent skills and a database of skill weights, and uses a processor to compute an optimum agent selection, thereby directly controlling the routing of the call (Compl. ¶11; ’979 Patent, Abstract).
• Asserted Claims: The complaint asserts "one or more claims" without specifying them (Compl. ¶30).
• Accused Features: The complaint alleges that Defendant’s unnamed "Exemplary Defendant Products" practice the claimed technology for intelligent call routing (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 describes a communications system where an optimal target for a communication is determined through a combinatorial optimization. The system considers characteristics of both the communication and at least three potential targets to determine the best match, with the optimization potentially including a cost-benefit analysis (Compl. ¶12; ’253 Patent, Abstract).
• Asserted Claims: The complaint asserts "one or more claims" without specification (Compl. ¶36).
• Accused Features: The complaint alleges that Defendant’s unnamed "Exemplary Defendant Products" utilize the claimed combinatorial optimization methods for call routing (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, related to the ’420 Patent, discloses a method for matching entities by defining targeting parameters for a first entity (e.g., a caller) and characteristic parameters for a plurality of second entities (e.g., agents). It then performs an automated optimization based on the economic surplus of a match and the opportunity cost of making a second entity unavailable for other potential matches (Compl. ¶13; ’086 Patent, Abstract).
• Asserted Claims: The complaint asserts "one or more claims" without specification (Compl. ¶42).
• Accused Features: The complaint alleges that Defendant’s unnamed products use the claimed auction-based matching methods in their customer communication systems (Compl. ¶42, ¶47).

III. The Accused Instrumentality

Product Identification

• The complaint identifies the accused instrumentalities as the "Exemplary Defendant Products" but does not name any specific product, method, or service offered by Defendant Farmers Group Inc. (Compl. ¶15, ¶21, ¶30, ¶36, ¶42).

Functionality and Market Context

• The complaint alleges that the unnamed Defendant products "practice the technology claimed" by the patents-in-suit (Compl. ¶17, ¶26, ¶32, ¶38, ¶47). Based on the nature of the asserted patents, the accused functionality concerns the systems and methods Defendant uses to route customer communications, such as telephone calls, to its agents or other resources. The complaint does not provide sufficient detail for analysis of the specific technical functionality or market context of any accused instrumentality.
• No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references, but does not include, claim chart exhibits that allegedly compare the asserted patent claims to the accused products (Compl. ¶17, ¶18, ¶26, ¶27, ¶32, ¶33, ¶38, ¶39, ¶47, ¶48). For each asserted patent, the complaint makes a conclusory allegation that the "Exemplary Defendant Products incorporated in these charts satisfy all elements of the Exemplary [...] Patent Claims" (Compl. ¶17, ¶26, ¶32, ¶38, ¶47). Without the claim charts or a more detailed narrative theory of infringement, a tabular analysis is not possible. The infringement theory appears to be that Defendant's internal and customer-facing communication systems perform intelligent, optimized, or auction-based routing that meets the limitations of the asserted claims.

Identified Points of Contention

• Factual Questions: Given the absence of specific product identifications, a primary point of contention will be evidentiary. A key question is what evidence Plaintiff will present to demonstrate that any of Defendant's systems actually perform the specific, multi-step optimization methods required by the asserted claims, as opposed to conventional, rule-based call routing.
• Scope Questions: The asserted claims rely on abstract concepts such as "auction," "economic surplus," and "maximizing an aggregate utility." A central legal question will be whether these terms, as defined and used within the patents, can be construed to read on the real-world processes allegedly used by Defendant's customer service systems.

V. Key Claim Terms for Construction

Term for Construction: "automated optimization with respect to an economic surplus"

• Source: ’420 Patent, Claim 1
• Context and Importance: This term is central to the novelty of the ’420 Patent. The case may turn on whether Defendant's routing logic, whatever it may be, can be characterized as performing an "optimization" and whether the factors it considers can be characterized as an "economic surplus." Practitioners may focus on this term because its abstract nature creates ambiguity in applying it to a concrete system.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification suggests that the optimization can be based on a "global minimization of the cost function or the like," which could be interpreted broadly to include general business goals beyond strict financial calculations (’420 Patent, col. 4:8-12).
  • Evidence for a Narrower Interpretation: The specification also provides more concrete financial examples, discussing factors like "training cost" and agent salaries, and presents the optimization in mathematical formulas, which may support a narrower construction tied to quantifiable economic metrics (’420 Patent, col. 24:1-50).

Term for Construction: "maximizing an aggregate utility"

• Source: ’748 Patent, Claim 1
• Context and Importance: This term is the core functional limitation of Claim 1 of the ’748 Patent. The infringement dispute will likely focus on whether Defendant's system performs a process that can be fairly described as "maximizing" a calculated "aggregate utility," or if it simply follows a set of pre-defined routing rules.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent describes "utility" as potentially including non-economic factors like "customer satisfaction," which could support a broader reading that covers any system aiming to improve overall performance based on multiple factors (’748 Patent, col. 24:36-40).
  • Evidence for a Narrower Interpretation: The patent describes a detailed, multi-step process for calculating and optimizing a cost-utility function, referencing specific inputs like agent skill scores and caller characteristics, which could support a narrower construction requiring a specific type of algorithmic maximization (’748 Patent, col. 23:23-24:67).

VI. Other Allegations

Indirect Infringement

• The complaint alleges induced infringement for the ’748 and ’086 Patents. The allegations are based on Defendant's distribution of "product literature and website materials" that allegedly instruct end users on how 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 and the corresponding claim charts (Compl. ¶25, ¶46).

Willful Infringement

• The complaint does not use the word "willful" but alleges "Actual Knowledge of Infringement" for the ’748 and ’086 Patents based on the service of the complaint and attached claim charts (Compl. ¶23, ¶44). This allegation may form the basis for a claim of post-suit willful infringement.

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

• A core issue will be one of definitional scope: can abstract patent terms such as "auction," "economic surplus," and "maximizing aggregate utility," which are rooted in economic theory, be construed to cover the concrete operational logic of a commercial insurance company's customer communication systems?
• A second key issue will be one of evidentiary sufficiency: given the complaint's lack of specificity regarding the accused products, a central question will be whether the plaintiff's allegations meet the plausibility standard for pleading patent infringement and what factual evidence can be marshaled to prove that the defendant's systems perform the specific, multi-step optimization functions required by the claims.
