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.

The Invention Explained

• Problem Addressed: The patent's background section describes the inefficiencies of traditional call centers, which typically use simple "first-come-first-served" logic to route inbound calls to agents, leading to suboptimal matches and resource allocation ('420 Patent, col. 2:42-53).
• The Patented Solution: The invention proposes a more sophisticated matching system that functions like an auction. It defines parameters for both the incoming entity (e.g., a customer call) and the available resources (e.g., agents) and then performs an "automated optimization" to find the best match based on factors like "economic surplus" and "opportunity cost" ('420 Patent, Abstract; col. 4:4-10). This allows for skill-based routing that considers a global minimization of a cost function rather than just queue order ('420 Patent, col. 4:4-10).
• Technical Importance: The technology represents a shift from simple queue management to dynamic, multi-factorial resource optimization in telecommunications, aiming to improve efficiency and outcomes in high-volume interaction environments like call centers ('420 Patent, col. 2:26-34).

Key Claims at a Glance

• The complaint asserts one or more "exemplary method claims" without specifying them (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 representing characteristic parameters for each of a plurality of second entities
  • performing an automated optimization with respect to an economic surplus of a match between the first entity and one of the second entities
  • performing the optimization also with respect to an opportunity cost of the unavailability of that 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

• Patent Identification: U.S. Patent No. 10,491,748, Intelligent communication routing system and method, issued November 26, 2019.

The Invention Explained

• Problem Addressed: As a member of the same patent family, the '748 Patent addresses the same technical problem of inefficient call routing in telecommunication systems ('748 Patent, col. 2:42-53).
• The Patented Solution: This patent frames the solution around maximizing an "aggregate utility." It describes a system that represents both communication sources (e.g., callers) and targets (e.g., agents) with predicted characteristics and an associated "economic utility." The system then determines an optimal routing by maximizing the combined utility of the matches, moving beyond simple one-to-one pairing to a more holistic system optimization ('748 Patent, Abstract; col. 24:28-43).
• Technical Importance: This approach advances skill-based routing by incorporating economic principles, allowing a call center to make routing decisions based not just on agent skills but also on predicted business value and overall system efficiency ('748 Patent, col. 24:30-40).

Key Claims at a Glance

• The complaint asserts "exemplary claims" without further specification (Compl. ¶21). Independent claim 1 is representative.
• Essential elements of Claim 1 include:
  • representing a plurality of predicted characteristics of a plurality of communications sources, each having an economic utility
  • representing a plurality of predicted characteristics of a plurality of communications targets, each having an economic utility
  • 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.

Multi-Patent Capsule Summaries

• 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 April 4, 2006 (Compl. ¶11).
  • Technology Synopsis: This earlier patent in the family discloses a communication management system that computes an "optimum" agent selection based on a communications classification. It proposes moving beyond simple routing to a system that uses a database of skill weights and agent scores to perform a cost-benefit analysis for routing calls (Compl. ¶30; '979 Patent, Abstract).
  • Asserted Claims: One or more "exemplary method claims" (Compl. ¶30).
  • Accused Features: The "Exemplary Defendant Products" are accused of practicing the claimed technology (Compl. ¶30).

• 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 September 11, 2007 (Compl. ¶12).
  • Technology Synopsis: This patent describes a system where communications are received and classified, characteristics of potential targets (e.g., agents) are stored, and an optimal target is determined based on both sets of characteristics. The determination and routing are performed by a "common platform," emphasizing the integration of the intelligent decision-making process with the routing function ('253 Patent, Abstract).
  • Asserted Claims: One or more "exemplary method claims" (Compl. ¶36).
  • Accused Features: The "Exemplary Defendant Products" are accused of practicing the claimed technology (Compl. ¶36).

  • Technology Synopsis: Similar to the '420 Patent, this patent describes a method for matching entities by defining targeting parameters for a first entity and characteristic parameters for second entities. It claims performing an automated optimization based on the "economic surplus" of a match and the "opportunity cost" of making that match, framing the routing decision as an economic calculation ('086 Patent, Abstract).
  • Asserted Claims: One or more "exemplary claims" (Compl. ¶42).
  • Accused Features: The "Exemplary Defendant Products" are accused of practicing the claimed technology (Compl. ¶42).

III. The Accused Instrumentality

Product Identification

• The complaint refers to the accused instrumentalities as the "Exemplary Defendant Products" (Compl. ¶15). It does not specifically name any products, methods, or services in the body of the complaint, instead incorporating by reference a series of exhibits containing claim charts (Compl. ¶¶17, 26, 32, 38, 47).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the functionality or market context of the accused products. It alleges generally that Defendant makes, uses, sells, and tests these products (Compl. ¶¶15-16). Given Defendant's business as a food franchisor, the accused instrumentalities may relate to customer service call centers, franchise management systems, or online/telephone ordering platforms.

IV. Analysis of Infringement Allegations

The complaint alleges infringement of all five patents-in-suit but does not provide claim charts or detailed infringement theories in the body of the document. Instead, it incorporates by reference Exhibits 6, 7, 8, 9, and 10, which allegedly contain charts comparing the asserted patent claims to the "Exemplary Defendant Products" (Compl. ¶¶17, 26, 32, 38, 47). As these exhibits are not attached to the publicly filed complaint, a detailed claim chart summary cannot be constructed. The narrative theory of infringement is that the accused products "practice the technology claimed" in the patents and "satisfy all elements" of the asserted claims as set forth in the charts (Compl. ¶17).

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Scope Questions: The patents-in-suit are described in the context of sophisticated call centers with agents possessing a variety of skills ('420 Patent, col. 3:36-51). A primary point of contention may be whether the terminology used in the claims, such as "agent," "economic surplus," and "call center," can be construed to cover the specific systems and personnel used in Defendant's food franchise operations.
  • Technical Questions: The complaint does not provide sufficient detail to identify specific technical questions. A central technical question, once evidence is presented, will be whether Defendant's systems perform the specific "multifactorial optimization" required by the claims, or a more conventional routing method that does not meet the claim limitations.

V. Key Claim Terms for Construction

• The Term: "automated optimization with respect to an economic surplus" (from Claim 1 of the '420 Patent).
• Context and Importance: This term appears to be the central inventive concept. The infringement analysis will likely depend on whether Defendant's system performs a calculation that qualifies as an "optimization" and whether the factors considered can be defined as an "economic surplus." Practitioners may focus on this term because its construction will determine whether simple rules-based routing infringes, or if a more complex, value-based calculation is required.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself is broad and does not limit "economic surplus" to monetary value. The specification notes that the target of a communication can be defined by an "algorithm, rather than a predetermined address or simple rule," which may support a broad interpretation covering various forms of complex decision-making ('420 Patent, col. 18:16-20).
  • Evidence for a Narrower Interpretation: The detailed description provides examples of an "economic parameter" in the context of "sales volume, profit, or the like" and discusses converting non-economic goals like "customer satisfaction" into economic terms for use in the optimization ('420 Patent, col. 24:30-43). This language could support a narrower construction requiring a calculation tied to cognizable business or financial metrics.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the '748 and '086 Patents. The basis for inducement is Defendant's alleged distribution of "product literature and website materials" that instruct end users on how to use the accused products in a manner that infringes the patents (Compl. ¶¶24, 45).
• Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. However, for the '748 and '086 Patents, it alleges that the service of the complaint constitutes "actual knowledge of infringement" (Compl. ¶¶23, 44). This allegation may 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

• A core issue will be one of definitional scope: can the patent claims, which are described in the context of optimizing resources in telecommunications systems like multi-skilled call centers, be construed to cover the business and customer service systems of a food franchisor? The interpretation of terms like "agent" and "economic surplus" will be central to this question.
• A key evidentiary question will be one of operational equivalence: once the specifics of the accused systems are detailed, the case will likely turn on whether they perform the specific, multi-factor "automated optimization" required by the claims. The central dispute will be whether the accused systems conduct a sophisticated, value-based calculation or a more conventional form of rules-based routing that falls outside the scope of the patents.
