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 section describes the inefficiency of traditional call center routing systems, such as Automatic Call Distributors (ACDs), which typically use simplistic rules like first-in-first-out or longest-idle-agent. These methods are often suboptimal for matching a caller’s specific needs with the most qualified available agent, leading to inefficient resource use and poor customer service. (’420 Patent, col. 2:26-34).
• The Patented Solution: The invention proposes a system that treats the matching of a "first entity" (e.g., a caller) with a "second entity" (e.g., a call agent) as an auction. The system defines parameters for both entities using "multivalued scalar data" and then performs an "automated optimization" to find the best match. This optimization seeks to maximize an "economic surplus" while also considering the "opportunity cost" of making an agent unavailable for other potential matches. (’420 Patent, Abstract; col. 2:42-53). Figure 1 illustrates a process flow for call routing that considers factors beyond simple queuing, such as optimizing a cost-utility function. (’420 Patent, Fig. 1).
• Technical Importance: This economic model-based approach to routing allows for more dynamic and nuanced decision-making than conventional rule-based systems, enabling a communications network to allocate resources based on calculated value rather than simple queuing order. (’420 Patent, col. 2:26-41).

Key Claims at a Glance

• The complaint asserts one or more "exemplary claims" without specifying them (Compl. ¶15). The first independent claim is Claim 1, a method claim.
• Claim 1 includes the following essential elements:
  • 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 respective match of the first entity with one of the second entities.
  • The optimization also considers an opportunity cost of the unavailability of that second entity for matching with an alternate first entity.
• The complaint does not explicitly reserve the right to assert dependent claims but makes a general allegation of infringement of "one or more 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, the background of the ’748 Patent describes the limitations of conventional call center management, where routing decisions fail to optimally match caller needs with agent skills, resulting in transactional inefficiencies. (’748 Patent, col. 4:35-51).
• The Patented Solution: The invention is a communications routing system that evaluates pairings between a requestor and multiple available partners using an "optimizing algorithm." The system estimates characteristics for the request and determines characteristics for the partners, then evaluates potential pairings based on these characteristics to generate a control signal that establishes the communication channel. (’748 Patent, Abstract; col. 3:1-12). This provides an intelligent, low-level routing architecture that can make sophisticated pairing decisions.
• Technical Importance: This technology integrates intelligent, multi-factor decision-making directly into the communications routing layer, aiming to improve efficiency over systems where such logic is handled by separate, high-level software platforms. (’748 Patent, col. 18:8-23).

Key Claims at a Glance

• The complaint asserts "exemplary claims" without specifying them (Compl. ¶21). The first independent claim is Claim 1, a method claim.
• Claim 1 includes the following essential elements:
  • Estimating at least one content-specific or requestor-specific characteristic associated with a request.
  • Determining a set of available partners, each having at least one respective partner characteristic.
  • Evaluating, with an automated processor, a plurality of pairings of the request with different available partners according to an evaluator for valuing pairings.
  • Generating a control signal, selectively dependent on the evaluation, for establishing a communication channel.
• The complaint makes a general allegation of infringement of "one or more claims" (Compl. ¶21).

U.S. Patent No. 7,023,979 - “Telephony control system with intelligent call routing,” issued April 4, 2006

Technology Synopsis

This patent addresses the inefficiency of traditional telephony routing by disclosing a control system where the intelligence for routing decisions is integrated at a low level. The system uses an optimizing algorithm to resolve a communication's target based on characteristics of the call and the available agents, rather than relying on a separate, high-level management system, thereby aiming to reduce latency and system complexity. (Compl. ¶11; ’979 Patent, col. 18:8-23).

Asserted Claims

The complaint does not specify claims but references an external exhibit (Compl. ¶30). Independent claims of the patent are 1, 10, 17, 18, and 19.

Accused Features

The complaint alleges that Defendant's "Exemplary Defendant Products" directly infringe by embodying the claimed intelligent call routing system (Compl. ¶30).

U.S. Patent No. 7,269,253 - “Telephony control system with intelligent call routing,” issued September 11, 2007

Technology Synopsis

This patent describes a communications management system that performs a combinatorial optimization to match communications with available agents. The system determines an optimal pairing by considering a cost-benefit analysis across a set of possible matches, moving beyond simple one-to-one comparisons to find a globally better routing solution for a group of concurrent communications. (Compl. ¶12; ’253 Patent, Abstract).

Asserted Claims

The complaint does not specify claims but references an external exhibit (Compl. ¶39). Independent claims of the patent are 1 and 21.

Accused Features

The complaint alleges that Defendant's "Exemplary Defendant Products" practice the claimed technology for intelligent call routing (Compl. ¶39).

U.S. Patent No. 9,456,086 - “Method and system for matching entities in an auction,” issued September 27, 2016

Technology Synopsis

This patent discloses a method for matching entities by conducting an auction that is sensitive to both "economic factors" and "non-economic factors." The non-economic factors comprise the optimality of matching profiles between entities (e.g., a caller and an agent). The system is designed to allow economic factors to compensate for a suboptimal profile match, enabling a more flexible and value-driven routing decision. (Compl. ¶13; ’086 Patent, Abstract).

Asserted Claims

The complaint does not specify claims but references an external exhibit (Compl. ¶45). Independent claims of the patent are 1 and 15.

Accused Features

The complaint alleges that Defendant's "Exemplary Defendant Products" infringe by using a system for matching entities in an auction (Compl. ¶45).

III. The Accused Instrumentality

Product Identification

The complaint refers generally to "Exemplary Defendant Products" without identifying any specific product, service, or method by name (Compl. ¶15).

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the accused instrumentality's functionality or market context. It makes only conclusory allegations that the unspecified products "practice the technology claimed" by the patents-in-suit (Compl. ¶17, ¶26, ¶35, ¶41, ¶50). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint incorporates infringement allegations by reference to external claim chart exhibits (Exhibits 6-10), which were not filed with the complaint (Compl. ¶18, ¶27, ¶36, ¶42, ¶51). The narrative infringement theory is that the unspecified "Exemplary Defendant Products" practice the technology claimed by the asserted patents and "satisfy all elements of the Exemplary... Patent Claims" (e.g., Compl. ¶17). Due to the absence of both specific product identification and claim charts, a detailed infringement analysis is not possible based on the complaint alone.

Identified Points of Contention

• Scope Questions: A central question will be whether the routing logic in Defendant’s actual products, once identified, falls within the scope of patent terms like “auction,” “automated optimization,” and “economic surplus.” The defense may argue its systems employ conventional, non-infringing routing rules that do not perform the specific economic calculations or auction-based matching required by the claims.
• Technical Questions: A key evidentiary question for the Plaintiff will be to demonstrate how Defendant’s products technically perform the multi-factorial optimizations described in the patents. For example, what evidence indicates that the accused systems calculate an “opportunity cost” of assigning an agent (’420 Patent) or use “economic factors [to] compensate for a suboptimality of a matching of profiles” (’086 Patent) as required by the respective claims?

V. Key Claim Terms for Construction

The Term: "automated optimization" (’420 Patent, Claim 1)

Context and Importance

This term is central to the claimed invention, as it defines the core function of the routing system. Its construction will likely determine whether a wide range of automated routing systems infringe, or only those performing specific, complex calculations. Practitioners may focus on this term because it distinguishes the invention from prior art simple routing rules.

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: The specification discusses optimizing a general "cost-utility function" and a "cost-benefit outcome," language that could be argued to encompass any automated process that improves routing efficiency over a baseline. (’420 Patent, col. 9:60-68).
• Evidence for a Narrower Interpretation: The specification provides detailed mathematical formulas for the cost function, including specific variables for agent cost, training utility, and opportunity cost. (’420 Patent, col. 24:1-67). The patent’s repeated references to "economic surplus" and "opportunity cost" may support a narrower construction limited to systems that perform explicit economic modeling.

The Term: "economic surplus" (’420 Patent, Claim 1)

Context and Importance

This term appears to be a critical limitation on the type of "automated optimization" performed. The dispute will likely center on whether this term requires a formal calculation consistent with its meaning in the field of economics or can be interpreted more broadly as a generic "benefit" or "value."

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: A party might argue that in the context of the patent, the term is used colloquially to mean the overall value or utility generated by a successful match, not a term of art from economic theory.
• Evidence for a Narrower Interpretation: The abstract and detailed description repeatedly frame the invention in economic terms, referencing "economic factors," "cost-utility function," and "opportunity cost," suggesting the inventors intended the term to have its specific, technical meaning. (’420 Patent, Abstract; col. 23:30-41).

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement for U.S. Patent Nos. 10,491,748, 7,023,979, and 9,456,086. 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). Knowledge and intent are alleged to exist at least from the date of service of the complaint (Compl. ¶25, ¶34, ¶49).

Willful Infringement

The complaint does not include a separate count for willful infringement. However, it alleges that Defendant gained "actual knowledge" of the patents upon service of the complaint and "continues to make, use, test, sell, offer for sale, market, and/or import" the accused products despite that knowledge, which may form the basis for a future claim of post-filing willfulness (Compl. ¶23-24, ¶32-33, ¶47-48).

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

• A core issue will be one of evidentiary sufficiency: Given the complaint's lack of specificity regarding the accused products, a key question is what evidence Plaintiff can produce to show that Defendant’s systems technically perform the complex, economic-based “automated optimization” and “auction” functionalities required by the patent claims, as opposed to conventional, non-infringing routing logic.
• A central legal question will be one of definitional scope: The outcome will likely depend on whether key claim terms such as “automated optimization” and “economic surplus” are construed broadly to cover any intelligent routing that improves efficiency, or narrowly to require the specific economic models and calculations detailed in the patent specifications.
