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 inefficiency of traditional call center management, where routing calls based on simple rules (e.g., first-come-first-served) or static agent groupings leads to suboptimal outcomes, such as routing a customer to an under-skilled or over-skilled agent (’420 Patent, col. 4:35-67).
  • The Patented Solution: The invention proposes a system that treats the matching of a "first entity" (e.g., a caller) to a "second entity" (e.g., an agent) as an optimization problem. It defines parameters for both entities and performs an "automated optimization" that considers not only the quality of a potential match (its "economic surplus") but also the "opportunity cost" of making a particular agent unavailable for a future, potentially higher-value interaction (’420 Patent, Abstract; col. 21:5-12). Figure 3 illustrates this process, showing "Call Classification Vector[s]" being fed into a system that uses agent characteristics and cost functions to route the call via a "Call Router" (’420 Patent, Fig. 3).
  • Technical Importance: This approach allows for more dynamic and economically efficient resource allocation in a communications network by treating each routing decision as part of a global optimization problem rather than an isolated event (’420 Patent, col. 24:41-50).
• Key Claims at a Glance:
  • The complaint asserts one or more claims of the ’420 Patent, but does not identify them specifically (Compl. ¶15). Independent claim 1 is representative of the core invention.
  • The essential elements of independent claim 1 include:
    • Defining multivalued scalar data for a first entity (representing "inferential targeting parameters") and for a plurality of second entities (representing "characteristic parameters").
    • Performing an automated optimization regarding (1) an "economic surplus" of a match between the first entity and a second entity, and (2) an "opportunity cost" of making that second entity unavailable for an alternate first entity.
  • The complaint reserves the right to assert infringement of claims other than those charted in its unprovided exhibits (Compl. ¶15).

U.S. Patent No. 10,491,748: “Intelligent communication routing system and method” (Issued November 26, 2019)

• The Invention Explained:
  • Problem Addressed: The patent addresses the same technical field as the ’420 Patent: the limitations of conventional, non-deterministic, and rule-based systems for routing communications in environments like call centers (’748 Patent, col. 2:1-24).
  • The Patented Solution: The invention is a communications routing system that represents both "communications sources" and "communications targets" using predicted characteristics, each associated with an "economic utility." The system then determines an "optimal routing" by "maximizing an aggregate utility" across all potential pairings, considering the characteristics of both the source and destination (’748 Patent, Abstract). The flowchart in Figure 1 details a process that optimizes a "cost-utility function" for either short-term efficiency or long-term call center operation (’748 Patent, Fig. 1).
  • Technical Importance: The system aims to provide a more sophisticated routing decision framework that optimizes for the total utility of the entire system, rather than just locally optimizing individual connections (’748 Patent, col. 27:10-23).
• Key Claims at a Glance:
  • The complaint asserts one or more claims of the ’748 Patent without specifying them (Compl. ¶21). Independent claim 1 captures the invention's primary scope.
  • The essential elements of independent claim 1 include:
    • A communications router for:
    • Representing predicted characteristics of communications sources, each having an economic utility.
    • Representing predicted characteristics of communications targets, each having an economic utility.
    • Determining an optimal routing by maximizing an aggregate utility with respect to the predicted characteristics.
  • Plaintiff reserves the right to assert additional claims (Compl. ¶21).

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

• Patent Identification: “Telephony control system with intelligent call routing,” issued April 4, 2006 (Compl. ¶11).
• Technology Synopsis: This patent, which shares a common ancestor with the ’420 Patent, describes an intelligent call routing system for telephony. The invention moves beyond simple routing rules to incorporate more complex factors, such as agent skills and call characteristics, to optimize the handling of communications in a call center environment (Compl. ¶11; '420 Patent, col. 1:18-24).
• Asserted Claims: The complaint alleges infringement of "exemplary method claims" but does not identify specific claims, instead incorporating by reference an unprovided exhibit (Compl. ¶30, ¶32).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in charts that are not provided with the complaint (Compl. ¶30).

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

• Patent Identification: “Telephony control system with intelligent call routing,” issued September 11, 2007 (Compl. ¶12).
• Technology Synopsis: As a related patent to the ’979 Patent, this invention also pertains to intelligent call routing in a telephony system. It aims to improve upon traditional automatic call distributors by using more sophisticated logic to match incoming calls with available agents based on a variety of parameters (Compl. ¶12; '420 Patent, col. 1:18-24).
• Asserted Claims: The complaint alleges infringement of "exemplary method claims" but does not identify specific claims, incorporating them by reference from an unprovided exhibit (Compl. ¶36, ¶38).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in charts that are not provided with the complaint (Compl. ¶36).

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

• Patent Identification: “Method and system for matching entities in an auction,” issued September 27, 2016 (Compl. ¶13).
• Technology Synopsis: This patent, from the same family as the ’420 Patent, describes a system where entities (e.g., callers and agents) are matched via an auction mechanism. This introduces economic principles into the routing decision, allowing for a competitive determination of the optimal pairing based on both economic and non-economic factors (Compl. ¶13; '420 Patent, col. 1:18-24).
• Asserted Claims: The complaint alleges infringement of "exemplary claims" but does not identify specific claims, incorporating them by reference from an unprovided exhibit (Compl. ¶42, ¶47).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" identified in charts that are not provided with the complaint (Compl. ¶42).

III. The Accused Instrumentality

• Product Identification: The complaint does not identify any specific accused products, methods, or services by name. It refers generally to "Exemplary Defendant Products" that are identified in claim charts attached as Exhibits 6-10 (Compl. ¶15, ¶21, ¶30, ¶36, ¶42). These exhibits were not filed with the complaint.
• Functionality and Market Context: The complaint does not provide sufficient detail for analysis of the functionality or market context of the accused instrumentalities. All such descriptions are incorporated by reference to the unprovided exhibits (Compl. ¶17, ¶26, ¶32, ¶38, ¶47).

IV. Analysis of Infringement Allegations

The complaint does not provide a narrative infringement theory or substantive claim charts in the body of the document. Instead, it alleges that infringement is demonstrated in charts attached as Exhibits 6 through 10, which were not provided with the publicly filed complaint (Compl. ¶17-18, ¶26-27, ¶32-33, ¶38-39, ¶47-48). Therefore, a detailed analysis of the infringement allegations is not possible from the complaint itself.
No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Evidentiary Questions: The primary point of contention will be factual and evidentiary. Since the complaint lacks any specific allegations linking Defendant's products to the patent claims, a central question will be what evidence Plaintiff can produce to show that Defendant's systems perform the specific functions required, such as "performing an automated optimization with respect to an economic surplus" ('420 Patent) or "maximizing an aggregate utility" ('748 Patent).
  • Scope Questions: A likely area of dispute will concern the scope of the claimed abstract concepts. For example, a question for the court may be whether the term "economic surplus," as used in the context of call center optimization, can be construed to cover the performance metrics allegedly used in Defendant’s systems.

V. Key Claim Terms for Construction

• The Term: "economic surplus" (from ’420 Patent, claim 1)
  • Context and Importance: This term is central to the optimization process claimed in the ’420 Patent. Its construction will determine whether a defendant's system, which optimizes for non-monetary metrics like customer satisfaction or agent efficiency, falls within the scope of the claim.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification discusses balancing competing goals beyond pure cost, such as providing "high quality and consistent service" and making "efficient use of call center resources," which may support a broader definition of "economic surplus" to include general utility or benefit (’420 Patent, col. 2:30-34).
    • Evidence for a Narrower Interpretation: The explicit use of the term "economic" may support a narrower construction limited to quantifiable financial value, profit, or cost savings, as opposed to more abstract measures of performance (’420 Patent, Abstract).
• The Term: "maximizing an aggregate utility" (from ’748 Patent, claim 1)
  • Context and Importance: This phrase defines the objective of the claimed routing system. The dispute will likely focus on whether the accused system performs a true mathematical "maximization" of a system-wide "aggregate" value, or merely improves individual outcomes in a way that does not infringe.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification describes balancing various factors, including "customer satisfaction," which may not be susceptible to a strict mathematical maximization, suggesting the term could be construed more broadly to mean "improving" or "optimizing" overall system performance (’748 Patent, col. 24:35-40).
    • Evidence for a Narrower Interpretation: The term "maximizing" has a precise mathematical meaning. The patent’s description of optimizing a "cost-utility function" suggests a formal, computational process to find an optimal solution, which could support a narrower interpretation requiring more than just a general improvement (’748 Patent, Fig. 1, step 308, 312).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the ’748 and ’086 Patents. The allegations state that Defendant distributes "product literature and website materials" that induce end users to operate the accused products in an infringing manner (Compl. ¶24, ¶45). The complaint asserts that Exhibits 7 and 10 provide extensive references to these materials (Compl. ¶24, ¶46).
• Willful Infringement: While the complaint does not contain a separate count for willful infringement, it alleges that service of the complaint constitutes "actual knowledge" of infringement for the ’748 and ’086 Patents (Compl. ¶23, ¶44). These allegations may form the basis for a claim of post-filing willful infringement if the case proceeds.

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

• A central issue will be one of evidentiary sufficiency: As the complaint is devoid of factual allegations describing the accused products, the case will depend entirely on whether discovery reveals that Defendant's systems perform the specific, multi-step optimization processes recited in the claims. The initial pleadings provide no information to assess the likelihood of such a technical overlap.
• The case will also turn on a question of definitional scope: can abstract claim terms such as "economic surplus" and "maximizing an aggregate utility," rooted in the patent's description of call center optimization, be construed broadly enough to read on the specific, yet-to-be-identified, functionalities of Defendant's products? The resolution of these terms will likely be dispositive.
