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 Mar. 19, 2019)

The Invention Explained

• Problem Addressed: The patent describes the challenge of managing call centers efficiently, noting that traditional routing systems (e.g., first-come-first-served or longest-idle-agent) often result in mismatches, such as routing a complex call to an under-skilled agent or a simple call to an over-skilled one, which reduces transactional throughput and efficiency (’420 Patent, col. 4:35-62).
• The Patented Solution: The invention proposes a system for matching a "first entity" (e.g., a caller) with a "second entity" (e.g., a call center agent) by performing an automated optimization. This optimization is based on maximizing the "economic surplus" of a potential match while also considering the "opportunity cost" of making that specific agent unavailable for other potential matches (’420 Patent, Abstract; col. 21:50-22:3). This reframes the routing problem as a form of economic auction to achieve more dynamic resource allocation.
• Technical Importance: The technical approach aims to move beyond static, rule-based call distribution to a more dynamic, economically optimized model for resource allocation in high-volume communication environments (’420 Patent, col. 2:25-35).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, instead incorporating by reference unprovided claim chart exhibits (Compl. ¶17-18). Independent claim 1 is representative of the patent’s core technology and includes the following essential elements:
  • A method for matching a first entity with at least one second entity selected from a plurality of second entities.
  • Defining multivalued scalar data representing inferential targeting parameters for the first entity and characteristic parameters for the 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 second entity for matching with an alternate first entity.
• The complaint states Plaintiff will identify claims for assertion at a later date (Compl. ¶15).

U.S. Patent No. 10,491,748 - "Intelligent communication routing system and method" (Issued Nov. 26, 2019)

The Invention Explained

• Problem Addressed: The patent addresses the same technical problem as the ’420 Patent: balancing the competing goals of customer service quality and operational efficiency in call centers, which traditional routing systems handle sub-optimally (’748 Patent, col. 2:25-34).
• The Patented Solution: The invention is a communications routing system that determines an optimal routing path by "maximizing an aggregate utility." This is achieved by representing both communication sources (e.g., callers) and targets (e.g., agents) with "predicted characteristics," and then calculating the routing linkage that produces the highest overall utility for the system (’748 Patent, Abstract; col. 23:22-24:50). The system can incorporate factors like training value and anticipated call outcomes into its utility function.
• Technical Importance: The disclosed method allows for routing decisions based on a holistic, utility-maximizing function that can incorporate diverse business objectives, rather than relying on simple, static routing rules (’748 Patent, col. 1:19-24).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, incorporating by reference an unprovided exhibit (Compl. ¶26-27). Independent claim 1 is representative and includes these essential elements:
  • 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 by maximizing an aggregate utility with respect to the predicted characteristics of the sources and targets.
• The complaint states Plaintiff will identify claims for assertion at a later date (Compl. ¶21).

Multi-Patent Capsule: U.S. Patent No. 7,023,979

• Patent Identification: U.S. Patent No. 7,023,979, “Telephony control system with intelligent call routing,” Issued Apr. 4, 2006.
• Technology Synopsis: This patent describes a communications management system for intelligent call routing. The system receives a communication classification, accesses a database of agent skill scores and a database of skill weights corresponding to the classification, and computes an optimum agent selection to control the call's routing (’979 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims, instead referring to an unprovided exhibit (Compl. ¶32-33). The patent contains two independent claims (1 and 16).
• Accused Features: The complaint does not identify specific accused product features, alleging only that "Exemplary Defendant Products" practice the technology as shown in the unprovided Exhibit 8 (Compl. ¶32).

Multi-Patent Capsule: U.S. Patent No. 7,269,253

• Patent Identification: U.S. Patent No. 7,269,253, “Telephony control system with intelligent call routing,” Issued Sep. 11, 2007.
• Technology Synopsis: This patent, related to the ’979 Patent, discloses a system for intelligent call routing that determines an optimal agent through a combinatorial optimization. The optimization is based on a correspondence between a call classification vector and a table of agent characteristic vectors, with the system controlling the call routing based on this determination (’253 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims, instead referring to an unprovided exhibit (Compl. ¶38-39). The patent contains one independent claim (1).

Multi-Patent Capsule: U.S. Patent No. 9,456,086

• Patent Identification: U.S. Patent No. 9,456,086, “Method and system for matching entities in an auction,” Issued Sep. 27, 2016.
• Technology Synopsis: This patent, related to the ’420 Patent, describes a method for matching a first entity with a second entity selected from a plurality of options. The matching is performed via an automated optimization that considers the economic surplus of a match and the opportunity cost of making a resource unavailable for an alternate match (’086 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims, instead referring to an unprovided exhibit (Compl. ¶47-48). The patent contains two independent claims (1 and 20).
• Accused Features: The complaint does not identify specific accused product features, alleging only that "Exemplary Defendant Products" practice the technology as shown in the unprovided Exhibit 10 (Compl. ¶47).

III. The Accused Instrumentality

• Product Identification: The complaint does not identify any specific accused products, systems, or services by name (Compl. ¶15, 21, 30, 36, 42). It refers generally to "Exemplary Defendant Products" and states that these are identified in claim chart exhibits (Exhibits 6-10), which were not filed with the complaint.
• Functionality and Market Context: The complaint does not provide sufficient detail for analysis of the functionality of any accused instrumentality. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint provides no narrative infringement theory for any of the asserted patents. Instead, it makes conclusory allegations that Defendant's unidentified "Exemplary Defendant Products" infringe one or more claims of each patent-in-suit "as set forth in these charts" incorporated by reference as Exhibits 6, 7, 8, 9, and 10 (Compl. ¶17, 26, 32, 38, 47). As these exhibits were not provided with the complaint, a substantive analysis of the infringement allegations is not possible based on the filed documents.

Identified Points of Contention

• Based on the asserted patents and the nature of the Defendant's business as a restaurant franchisor, several points of contention may arise.
  • Scope Questions: A primary question may be whether the term "auction," as used in the ’420 and ’086 Patents, can be construed to cover the customer service or order routing logic allegedly used by the Defendant. The analysis may turn on whether Defendant's system performs a function that can be technically characterized as an "automated optimization with respect to an economic surplus and an opportunity cost" (’420 Patent, Claim 1).
  • Technical Questions: For the ’748, ’979, and ’253 patents, a key question will be what evidence demonstrates that the accused systems perform the specific multifactorial optimizations required by the claims. For example, does the Defendant's system calculate an "aggregate utility" based on "predicted characteristics" of both callers and agents (’748 Patent, Claim 1), or does it use a simpler, non-infringing routing logic? The evidentiary basis for these allegations is currently absent from the complaint.

V. Key Claim Terms for Construction

For the ’420 Patent

• The Term: "automated optimization with respect to an economic surplus ... and an opportunity cost" (from Claim 1).
• Context and Importance: This phrase constitutes the central inventive concept of the claim. The infringement dispute will likely focus on whether the logic of the accused routing system, whatever it may be, can be fairly characterized as performing this specific, economically-defined optimization.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The Abstract describes the invention broadly as a "method for matching a first entity with at least one second entity," which could support application beyond traditional call centers (’420 Patent, Abstract).
  • Evidence for a Narrower Interpretation: The specification heavily details the invention in the context of call centers, using callers and agents as the primary examples and discussing factors like call duration and agent skill sets, which could suggest a narrower construction tied to that environment (’420 Patent, col. 21–26).

For the ’748 Patent

• The Term: "maximizing an aggregate utility" (from Claim 1).
• Context and Importance: This term is critical because it defines the goal of the claimed routing method. The parties may dispute what technical operations constitute "maximizing" and what factors can be included in the "aggregate utility."
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification notes that business goals like "customer satisfaction" can be normalized and included in the utility function, suggesting a flexible and broad definition of "utility" (’748 Patent, col. 24:35-40).
  • Evidence for a Narrower Interpretation: The patent provides a specific formula representing the cost function, which includes discrete terms for agent cost, change in agent value, anticipated transaction value, and opportunity cost, potentially limiting the scope of "aggregate utility" to models incorporating these specific factors (’748 Patent, col. 24:41-50).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the ’748 and ’086 Patents. It claims 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). The complaint refers to unprovided Exhibits 7 and 10 as containing this evidence (Compl. ¶24, 46).
• Willful Infringement: The complaint does not use the term "willful infringement." It alleges "Actual Knowledge of Infringement" for the ’748 and ’086 Patents, but bases this knowledge solely on "The service of this Complaint, in conjunction with the attached claim charts" (Compl. ¶23, 44). This frames the allegation as one of post-suit knowledge rather than pre-suit willfulness.

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

• A primary threshold issue will be one of evidentiary sufficiency: given that the complaint provides only conclusory allegations of infringement without identifying any specific accused products or mapping their functionality to claim elements, a central question is what factual evidence Plaintiff will introduce to substantiate its claims and satisfy the pleading standards under Twombly and Iqbal.
• A core technical issue will be one of conceptual scope: can the patent claims, which describe sophisticated economic models such as "auctions" (’420 and ’086 Patents) and "utility maximization" (’748 Patent), be construed to read on the potentially more conventional customer service and order routing systems used by a restaurant franchisor?
• A key legal question may concern claim construction: the viability of the infringement claims will depend heavily on whether terms like "economic surplus," "opportunity cost," and "aggregate utility" are interpreted broadly enough to encompass the functionalities of Defendant's systems or are construed more narrowly in line with the specific mathematical and call-center embodiments described in the patents.
