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’s background describes the inefficiencies in traditional call centers, which often use simple first-come-first-served or longest-idle-agent routing logic (Compl. ¶ 9; ’420 Patent, col. 3:1-14). These systems struggle to optimally match callers to agents with specific skills, leading to problems such as routing calls to under-skilled or over-skilled agents, which reduces transactional throughput and customer satisfaction (’420 Patent, col. 4:35-50).
• The Patented Solution: The invention proposes a more sophisticated matching method where both the caller (the "first entity") and the available agents (the "second entities") are defined by "multivalued scalar data" representing their respective characteristics and needs (’420 Patent, Abstract). The system then performs an "automated optimization" that considers not only the quality of a potential match (the "economic surplus") but also the "opportunity cost" of using a particular agent for one call when that agent might be better suited for another simultaneous or anticipated call (’420 Patent, Abstract; col. 24:43-50). This aims to improve global, long-term call center efficiency rather than just immediate call-handling speed (’420 Patent, col. 27:10-14).
• Technical Importance: The technology represents a shift from static, rule-based call routing to a dynamic, economically-driven optimization model for allocating human resources in real-time communications environments (’420 Patent, col. 21:1-8).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, referring only to "exemplary claims" in non-provided exhibits (Compl. ¶¶ 15, 17). Independent claim 1 is representative of the patent's core inventive concept.
• Independent Claim 1:
  • Defining multivalued scalar data for a first entity (e.g., a caller) representing its "inferential targeting parameters."
  • Defining multivalued scalar data for a plurality of second entities (e.g., agents) representing their "characteristic parameters."
  • Performing an automated optimization of the match with respect to an "economic surplus" and an "opportunity cost" of the agent's unavailability for an alternate match.
• The complaint reserves the right to assert additional claims (Compl. ¶ 15).

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

Issued November 26, 2019

The Invention Explained

• Problem Addressed: Similar to the ’420 Patent, this patent addresses the challenge of managing call centers to balance high-quality customer service with the efficient use of resources (’748 Patent, col. 1:29-34). The patent notes that simple routing rules fail to account for the complex, multi-variable nature of optimizing outcomes in a call center environment (’748 Patent, col. 3:15-21).
• The Patented Solution: The invention describes a routing system that models both communications sources (e.g., callers) and targets (e.g., agents) based on their predicted characteristics and an associated "economic utility" (’748 Patent, Abstract). The system then determines an "optimal routing" by "maximizing an aggregate utility" across all potential pairings, effectively treating the routing decision as a complex economic optimization problem rather than a simple queuing task (’748 Patent, Abstract; col. 24:29-42).
• Technical Importance: This approach allows a communications system to make routing decisions based on inferential, high-level business goals (like maximizing profit or customer satisfaction) rather than being limited to fixed, unambiguous targets like a specific phone number or agent queue (’748 Patent, col. 18:13-21).

Key Claims at a Glance

• The complaint does not specify which claims are asserted (Compl. ¶¶ 21, 26). Independent claim 1 is representative.
• Independent Claim 1:
  • Representing predicted characteristics of communication sources, each having an "economic utility."
  • Representing predicted characteristics of communication targets, each having an "economic utility."
  • Determining an optimal routing between sources and targets by "maximizing an aggregate utility" with respect to their predicted characteristics.
• The complaint reserves the right to assert additional claims (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 April 4, 2006 (Compl. ¶ 11).
• Technology Synopsis: This patent, an early patent in the asserted family, describes a telephony control system that moves beyond simple call routing. It proposes a system that can intelligently route calls by performing an optimization based on a cost-utility function, considering factors such as agent skill, training needs, and call center capacity to improve long-term operational efficiency (’979 Patent, col. 1:12-20, Fig. 1).
• Asserted Claims: The complaint does not specify asserted claims (Compl. ¶ 30).
• Accused Features: The complaint accuses unspecified "Exemplary Defendant Products" 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: As a continuation of the technology in the ’979 patent, this patent further details a system for intelligent call routing. It discloses a communications management system that uses a database of agent skill scores and a processor to compute an "optimum agent selection" based on the classification of an incoming communication, with the processor directly controlling the routing (’253 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims (Compl. ¶ 39).
• Accused Features: The complaint accuses unspecified "Exemplary Defendant Products" of practicing the claimed technology (Compl. ¶ 39).

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 September 27, 2016 (Compl. ¶ 13).
• Technology Synopsis: This patent describes matching two entities (e.g., a caller and an agent) by performing an automated, auction-style optimization. The system defines parameters for each entity and calculates an "economic surplus" for a potential match while also considering the "opportunity cost" of making that agent unavailable for other potential matches, thereby creating a competitive allocation of resources (’086 Patent, Abstract).
• Asserted Claims: The complaint does not specify asserted claims (Compl. ¶ 45).
• Accused Features: The complaint accuses unspecified "Exemplary Defendant Products" of practicing the claimed technology (Compl. ¶ 45).

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any specific accused products, methods, or services by name (Compl. ¶ 15). It refers generally to "Exemplary Defendant Products" and incorporates by reference claim charts from Exhibits 6 through 10, which were not filed with the complaint (Compl. ¶¶ 17, 26, 35, 41, 50).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the functionality of the accused instrumentalities. It makes only the conclusory allegation that the accused products "practice the technology claimed" by the patents-in-suit (Compl. ¶ 17). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint’s infringement allegations are made by reference to claim chart exhibits that were not provided with the public filing (Compl. ¶¶ 17-18, 26-27, 35-36, 41-42, 50-51). The narrative allegations are conclusory and state only that the "Exemplary Defendant Products" satisfy all elements of the asserted patent claims (Compl. ¶¶ 17, 26, 35, 41, 50). As a result, a claim chart summary cannot be constructed from the provided documents.

• Identified Points of Contention: Based on the asserted patents and the nature of Defendant's business in truck leasing and logistics, which presumably involves customer service call centers, the infringement analysis may raise several key questions:
  • ’420 Patent Scope Questions: Does Defendant’s system for routing customer service calls or logistics inquiries perform an "automated optimization" as claimed? What evidence demonstrates that this optimization considers both the "economic surplus" of a given match and the "opportunity cost" of an agent's unavailability for other tasks, as those terms are defined in the patent?
  • ’748 Patent Technical Questions: Does Defendant’s system assign a specific "economic utility" to both callers and agents? On what basis does the complaint allege that the system's routing logic functions to "maximize an aggregate utility," rather than operating on simpler principles like wait time or agent availability?

V. Key Claim Terms for Construction

• The Term: "economic surplus" and "opportunity cost" (’420 Patent, Claim 1)

• Context and Importance: These terms, borrowed from economics, are central to defining the scope of the claimed optimization. Their construction will be critical to determining infringement, as Plaintiff must show that the accused system calculates and considers these specific factors, not just general notions of efficiency. Practitioners may focus on whether these terms require a specific quantitative calculation or can be met by a system that implicitly or qualitatively weighs these factors.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification suggests these terms can be abstract, stating the system may be influenced by "non-economic factors" and "may include objective and subjective factors" (’420 Patent, col. 22:64-66). This could support an argument that any system balancing immediate call value against future agent availability meets the limitation.
  • Evidence for a Narrower Interpretation: The detailed description provides mathematical formulas for calculating cost functions, including terms for agent cost, anticipated value of a transaction, and opportunity cost (’420 Patent, col. 24:51-67). This may support a narrower construction requiring a system that performs explicit, quantitative calculations corresponding to these economic concepts.

• The Term: "economic utility" and "maximizing an aggregate utility" (’748 Patent, Claim 1)

• Context and Importance: Similar to the terms in the ’420 patent, the definition of these terms is vital. The dispute will likely center on whether Defendant's system, which may be designed to minimize wait times or balance workloads, can be characterized as maximizing a quantifiable "aggregate utility" derived from the "economic utility" of participants.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent defines "economic utility" broadly to include factors like "customer satisfaction" which are not purely financial (’748 Patent, col. 24:35-40). This language may support a construction where a system optimizing for qualitative goals still meets the "economic utility" limitation.
  • Evidence for a Narrower Interpretation: The abstract and summary repeatedly frame the invention in economic terms, such as determining an "optimal routing" by maximizing utility (’748 Patent, Abstract). This focus may support a narrower reading that requires a system proven to achieve a mathematically maximal outcome, rather than one that merely improves efficiency.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for the ’748, ’979, and ’086 patents (Compl. ¶¶ 25, 34, 49). The allegations are based on Defendant’s distribution of "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 does not contain an explicit count for willful infringement. However, for the ’748, ’979, and ’086 patents, it alleges that Defendant has had "actual knowledge" of infringement at least since the service of the complaint and has "actively, knowingly, and intentionally continued to induce infringement" (Compl. ¶¶ 23, 25, 32, 34, 47, 49). These allegations of post-suit knowledge could form the basis for a later claim of willful infringement.

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

1. Pleading Sufficiency: A threshold issue will be whether the complaint's allegations, which are entirely conclusory and rely on incorporated exhibits that were not filed, meet the plausibility standard required to survive a motion to dismiss under Federal Rules of Civil Procedure 12(b)(6) and the Twombly/Iqbal framework.
2. Claim Construction and Technical Proof: A central technical question will be one of definitional scope: can abstract economic concepts like "economic surplus," "opportunity cost," and "maximizing an aggregate utility" be construed to read on the real-world functionality of Defendant’s customer service and logistics management systems? The case will likely depend on expert testimony to translate the patent's theoretical models into the practical operations of the accused systems.
3. Patent Eligibility: A fundamental legal question will be one of patentable subject matter under 35 U.S.C. § 101. The court will likely be asked to determine whether the claims are directed to the abstract ideas of auction theory and economic optimization applied with generic computer components, and if so, whether they contain a sufficient "inventive concept" to be patent-eligible under the framework established in Alice Corp. v. CLS Bank.
