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 describes the inefficiency of traditional call centers, which typically use simple first-in, first-out routing. This can lead to mismatches where calls are routed to agents who are either under-skilled or over-skilled for the task, reducing overall transactional throughput (U.S. Patent No. 10,237,420, col. 4:35-65).
• The Patented Solution: The invention proposes an intelligent switching architecture that treats the matching of a communication (a "first entity") with a resource like a call center agent (a "second entity") as an auction. The system performs an "automated optimization" based on various parameters, including not only skill matching but also economic concepts such as the "economic surplus" of a potential match and the "opportunity cost" of making one agent unavailable for other potential matches (’420 Patent, Abstract; Fig. 3).
• Technical Importance: This approach models resource allocation in a communications network as a dynamic economic problem, allowing for more sophisticated and globally optimized routing decisions than traditional skill-based systems (’420 Patent, col. 5:20-30).

Key Claims at a Glance

• The complaint asserts exemplary method claims without specifying numbers (Compl. ¶15). Independent claim 1 is representative.
• Essential elements of Claim 1:
  • 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.
  • Defining multivalued scalar data representing "characteristic parameters" for each of the second entities.
  • Performing an automated optimization with respect to an "economic surplus" of a match and an "opportunity cost" of the unavailability of the second entity for an alternate match.
• 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" (Issued November 26, 2019)

The Invention Explained

• Problem Addressed: Similar to the ’420 Patent, this patent addresses the inefficiencies of conventional call centers. It notes that separating low-level call switching (e.g., in a PBX) from high-level management software creates performance latencies and limits the intelligence of real-time routing decisions (U.S. Patent No. 10,491,748, col. 2:1-24).
• The Patented Solution: The invention integrates intelligent, multifactorial optimization directly into the low-level communications control system. This system receives concurrent communications, classifies them using associated "classification factors," and performs an optimization against the characteristics of potential targets (e.g., agents) to determine and execute the optimal routing (’748 Patent, Abstract; Fig. 1).
• Technical Importance: By embedding complex optimization logic within the communications server itself, the invention aims to reduce latency and enable more dynamic, real-time routing decisions based on a wide range of variables beyond simple queuing rules (’748 Patent, col. 18:8-23).

Key Claims at a Glance

• The complaint asserts exemplary claims without specifying numbers (Compl. ¶21). Independent claim 1 is representative.
• Essential elements of Claim 1:
  • A communications routing system with a processor and memory.
  • Receiving a plurality of concurrent communications, each having associated "classification factors."
  • Storing information representing characteristics of a plurality of potential targets.
  • Performing a "multifactorial optimization" to determine an optimum target for each communication based on the classification factors and target characteristics.
  • Routing at least one communication to its determined optimum target.
• The complaint does not explicitly reserve the right to assert dependent claims.

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: Based on its title and relationship to the other patents-in-suit, this patent appears to cover an earlier iteration of the core technology: a telephony control system that uses intelligent algorithms, rather than simple rules, to route calls. The system likely computes an optimal agent selection based on various factors related to the call and available agents (U.S. Patent No. 7,023,979, Abstract).
• Asserted Claims: The complaint asserts exemplary method claims without specifying them (Compl. ¶30).
• Accused Features: The complaint alleges infringement by the "Exemplary Defendant Products" (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 shares its title with the ’979 Patent and appears to be part of the same family, directed at intelligent call routing in a telephony system. The invention involves a system that receives a communication, analyzes its classification, and computes an optimal agent selection based on a database of agent skills and skill weights (U.S. Patent No. 7,269,253, Abstract).
• Asserted Claims: The complaint asserts exemplary method claims without specifying them (Compl. ¶36).

• Technology Synopsis: This patent is a direct technological predecessor to the ’420 Patent, sharing its title and core inventive concept. The invention is a method for matching a first entity (e.g., a caller) with a second entity (e.g., an agent) by defining parameters for each and performing an automated optimization based on the "economic surplus" and "opportunity cost" of the match (U.S. Patent No. 9,456,086, Abstract).
• Asserted Claims: The complaint asserts exemplary claims without specifying them (Compl. ¶42).
• Accused Features: The complaint alleges infringement by the "Exemplary Defendant Products" (Compl. ¶42).

III. The Accused Instrumentality

Product Identification

• The complaint identifies the accused instrumentalities as the "Exemplary Defendant Products" (Compl. ¶15). It states these products are identified in charts incorporated as Exhibits 6 through 10; however, these exhibits were not attached to the publicly filed complaint.

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the accused products' specific functionality or market context. It alleges in a conclusory manner that the products "practice the technology claimed" by the patents-in-suit (Compl. ¶17, ¶26, ¶32, ¶38, ¶47). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references claim chart exhibits (Exhibits 6-10) that are not provided with the pleading (Compl. ¶17-18, ¶26-27, ¶32-33, ¶38-39, ¶47-48). The narrative infringement allegations are limited to assertions that the "Exemplary Defendant Products" satisfy all elements of the exemplary claims of the patents-in-suit. The complaint does not provide sufficient detail for analysis of specific infringement theories.

V. Key Claim Terms for Construction

’420 Patent

• The Term: "economic surplus"
• Context and Importance: This term is a cornerstone of the optimization step in claim 1. The viability of the infringement claim may depend on whether this term is construed broadly to include non-monetary metrics of efficiency or value, or narrowly to require a specific financial calculation that Defendant's system may not perform. Practitioners may focus on this term because its definition dictates the type of evidence needed to prove the accused optimization meets this limitation.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification suggests the optimization may be for "greatest efficiency, lowest cost, or other optimized variable," which may support a construction not strictly limited to financial surplus (’420 Patent, col. 4:8-10).
  • Evidence for a Narrower Interpretation: The term itself, along with the related claim term "opportunity cost," is rooted in economics, suggesting an intended meaning tied to financial or business value calculations (’420 Patent, Abstract).

’748 Patent

• The Term: "multifactorial optimization"
• Context and Importance: This term defines the core function of the claimed system. An infringement dispute may turn on how many and what types of "factors" are required for an optimization to be "multifactorial." A defendant could argue its system uses a simple, single-factor, or non-optimizing routing rule that falls outside the scope of this term.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification discloses a wide variety of factors that can be considered in the optimization, including agent skills, training needs, call characteristics, and business goals, suggesting the term is meant to be capacious (’748 Patent, col. 23:1-24:50).
  • Evidence for a Narrower Interpretation: The flowcharts in the patent depict distinct routing paths, such as one for when a call center is "near capacity" versus one that optimizes for "long term call center operation," which might support an argument that these are separate, sequential decisions rather than a single, unified "multifactorial optimization" (’748 Patent, Fig. 1).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement of the ’748 Patent and the ’086 Patent. 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, ¶45).
• Willful Infringement: Willfulness is not explicitly pleaded as a separate count, but the complaint alleges "Actual Knowledge of Infringement" for the ’748 and ’086 Patents based on the service of the complaint and its attached (but missing) claim charts (Compl. ¶23, ¶44). This forms a basis for alleging post-suit willful infringement. No facts suggesting pre-suit knowledge are alleged.

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

• A primary issue will be one of evidentiary sufficiency: given the complaint’s lack of specific technical allegations regarding the accused products, a key question is what evidence Plaintiff will be able to discover and present to demonstrate that Defendant's systems in fact perform the complex, optimization-based routing required by the asserted claims.
• A central legal question will be one of claim scope: can the term "economic surplus," which is rooted in financial and business theory, be construed to cover the technical efficiency or performance metrics that a communications routing system might optimize for, or is there a fundamental mismatch in the claimed concept and the accused technology's operation?
• A further dispositive question will be technical and functional: does the accused product's routing logic, once revealed, constitute a "multifactorial optimization" as claimed, or does it operate based on a simpler, sequential, or non-optimizing ruleset that would place it outside the scope of the patent claims?
