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 centers, which use simple "first-come-first-served" or basic skill-based routing to connect customers to agents, leading to suboptimal matches, delays, and inefficient use of resources (Compl. ¶9; ’420 Patent, col. 2:26-4:67).
  • The Patented Solution: The invention proposes a system that treats the matching of a "first entity" (e.g., an incoming call) with a "second entity" (e.g., a call center agent) as an auction. The system performs an automated optimization that considers not only the best skill-based match but also an "economic surplus" of the match and the "opportunity cost" of making a particular agent unavailable for other potential matches, thereby improving overall system efficiency (’420 Patent, Abstract; col. 20:5-24).
  • Technical Importance: This approach seeks to apply complex economic and game theory principles to telecommunications routing, moving beyond static rules to a dynamic, real-time optimization of resources in high-volume environments (’420 Patent, col. 21:5-8).
• Key Claims at a Glance:
  • The complaint alleges infringement of one or more claims, but does not identify specific claims, instead referring to charts in an external exhibit (Compl. ¶15). Independent claim 1 is representative.
  • Claim 1 Elements:
    • A method for matching a first entity with at least one second entity selected from a plurality of second entities.
    • Defining a plurality of multivalued scalar data representing inferential targeting parameters for the first entity.
    • Defining a plurality of multivalued scalar data for each of the plurality of second entities, representing characteristic parameters.
    • Performing an automated optimization with respect to an economic surplus of a respective match and an opportunity cost of the unavailability of the at least one second entity for matching with an alternate first entity.
  • The complaint does not explicitly reserve the right to assert dependent claims but refers generally to "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: The patent addresses the same general problem space as the ’420 Patent: the limitations of traditional, non-deterministic operating systems in managing real-time call center functions, which can lead to latencies and inefficient call routing (Compl. ¶10; ’748 Patent, col. 1:50-2:24).
  • The Patented Solution: The invention describes a communications routing system that uses an "economic utility" model to determine an "optimal routing" between communication sources and targets. It maximizes an "aggregate utility" based on the predicted characteristics of both the sources (e.g., callers) and the targets (e.g., agents), moving beyond simple skill matching to a broader utility-based optimization (’748 Patent, Abstract; col. 3:55-4:12).
  • Technical Importance: The system integrates intelligent, inferential routing logic at a low level within the communications management architecture, allowing for real-time, context-based routing decisions without relying on slower, high-level management software (’748 Patent, col. 18:8-23).
• Key Claims at a Glance:
  • The complaint alleges infringement of one or more claims without specifying them, referring instead to charts in an external exhibit (Compl. ¶21). Independent claim 1 is representative.
  • Claim 1 Elements:
    • A communications routing system and method.
    • Representing predicted characteristics of a plurality of communications sources, each having an economic utility.
    • Representing 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 but refers generally to "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 describes a communications management system for a call center that receives a "communications classification" and uses a database of agent skills and skill weights to compute an "optimum agent selection." The system then directly controls the routing of the communication to the selected agent, integrating the intelligent decision-making with the low-level telephony control (Compl. ¶11; ’979 Patent, Abstract).
• Asserted Claims: The complaint does not specify which claims are asserted (Compl. ¶30).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" but does not identify them or their features, instead referring to charts in an external exhibit (Compl. ¶30).

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

• Technology Synopsis: This patent discloses a system and method for routing communications based on a "combinatorial optimization." It involves receiving communications with associated classification information, storing characteristics of potential targets (e.g., agents), and determining an optimum target for each communication based on a cost-benefit analysis before routing the call (Compl. ¶12; ’253 Patent, Abstract).
• Asserted Claims: The complaint does not specify which claims are asserted (Compl. ¶39).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" but does not identify them or their features, instead referring to charts in an external exhibit (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, related to the ’420 Patent, describes a method for matching a "first entity" with a "second entity" through an "automated optimization." The optimization considers the "economic surplus" of a potential match and the "opportunity cost" of making a particular second entity unavailable for an alternate first entity (Compl. ¶13; ’086 Patent, Abstract).
• Asserted Claims: The complaint does not specify which claims are asserted (Compl. ¶45).
• Accused Features: The complaint alleges infringement by "Exemplary Defendant Products" but does not identify them or their features, instead referring to charts in an external exhibit (Compl. ¶45).

III. The Accused Instrumentality

• Product Identification: The complaint does not identify any accused product, method, or service by name (Compl. ¶¶15, 21, 30, 39, 45). It refers generically to "Exemplary Defendant Products" and "Defendant products" that are purportedly identified in external exhibits, which were not filed with the complaint (Compl. ¶17).
• Functionality and Market Context: The complaint provides no description of the functionality or market context of the accused instrumentalities. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint does not provide a factual basis for its infringement allegations in the body of the pleading. For each of the five asserted patents, it alleges direct infringement by Defendant's "making, using, offering to sell, selling and/or importing" the unidentified "Exemplary Defendant Products" (Compl. ¶¶15, 21, 30, 39, 45). The complaint states that infringement is detailed in claim charts provided as Exhibits 6 through 10, but these exhibits were not provided with the public filing (Compl. ¶¶17, 26, 35, 41, 50). Consequently, a detailed claim chart summary cannot be constructed.

• Identified Points of Contention:
  • Pleading Sufficiency Questions: The complaint’s failure to identify any specific accused product or provide any factual allegations of infringement beyond incorporating missing exhibits raises the question of whether it meets the pleading standards established by Twombly and Iqbal.
  • Scope Questions: A central issue may be whether the terminology of the patents, which is consistently rooted in the context of call centers, agents, and telecommunications routing, can be construed to read on the business operations of a car rental company. For example, a potential point of contention regarding the ’420 Patent is whether Defendant’s systems for processing customer reservations perform an "auction" to achieve a "match" as those terms are defined and used in the patent.
  • Technical Questions: Assuming a plausible claim construction, a key technical question will be what evidence exists that Defendant’s systems perform the specific, complex optimizations required by the claims. For instance, with respect to the ’748 Patent, a question arises as to whether Defendant's systems determine routing by "maximizing an aggregate utility" based on "predicted characteristics" or if they operate on simpler, predetermined business rules that fall outside the claim scope.

V. Key Claim Terms for Construction

• The Term: "auction" (’420 Patent, Claim 1)

  • Context and Importance: The ’420 Patent claims a "method and system for matching entities in an auction." The definition of "auction" will be critical to determining infringement, as Defendant's car rental business does not conduct auctions in the conventional sense. Practitioners may focus on this term because the infringement theory appears to depend on a non-traditional application of the term to a resource allocation process.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification suggests the term can apply broadly to communications routing, stating the system "conducts series of auctions...to determine the select respective communications path" (Compl. Ex. 1, Fig. 6). This may support an argument that "auction" should be construed to mean any competitive process for allocating a resource, not just a traditional sale.
    • Evidence for a Narrower Interpretation: The abstract and detailed description repeatedly frame the invention in economic terms like "economic surplus" and "opportunity cost" (’420 Patent, Abstract). This context may support a narrower construction requiring a process with explicit bidding or economic competition elements, which may not be present in a standard reservation system.

• The Term: "economic utility" (’748 Patent, Claim 1)

  • Context and Importance: The ’748 Patent's independent claims require determining an optimal routing by maximizing an "aggregate utility" where sources and targets each have an "economic utility." The definition of this term is central, as it may require a specific type of quantitative, economic-based assessment that Defendant's systems do not perform.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent does not appear to provide a specific definition of the term, which may support an argument for giving it its plain and ordinary meaning, potentially encompassing any measure of value or usefulness in a business context.
    • Evidence for a Narrower Interpretation: The specification discusses optimizing a "cost-utility function" that considers factors like "agent cost," "training cost," "sales volume, profit," and "customer satisfaction" converted into "economic terms" (’748 Patent, col. 24:12-40). This may support a narrower construction requiring a specific, multi-factor economic calculation, rather than a more general assessment of business value.

VI. Other Allegations

• Indirect Infringement: For the ’748, ’979, and ’086 Patents, the complaint alleges induced infringement. The allegations state that Defendant distributes "product literature and website materials inducing end users...to use its products in the customary and intended manner that infringes" the patents (Compl. ¶¶24, 33, 48). No specific literature or instructions are quoted or identified.
• Willful Infringement: The complaint does not use the word "willful." However, for the ’748, ’979, and ’086 Patents, it alleges that "service of this Complaint, in conjunction with the attached claim charts...constitutes actual knowledge of infringement" and that Defendant's infringement continued despite this knowledge (Compl. ¶¶23-24, 32-33, 47-48). The prayer for relief requests a declaration that the case is "exceptional" under 35 U.S.C. § 285 (Compl. p. 11). These allegations appear to lay the groundwork for a claim of post-filing willful infringement.

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

• A foundational issue will be one of pleading sufficiency: does the complaint, which fails to identify any specific accused product and relies entirely on incorporating missing exhibits, provide sufficient factual detail to state a plausible claim for relief?
• A core issue will be one of definitional scope: can the patents’ terminology, which is rooted in the technical context of call center agent routing (e.g., "auction," "economic surplus," "call classification vector"), be construed to cover the operations of a consumer-facing car rental reservation system?
• A key evidentiary question will be one of functional operation: assuming the claim terms are construed broadly enough to apply, what evidence will show that Defendant's systems actually perform the complex, multi-factor "automated optimization" and "utility maximization" functions required by the claims, as opposed to operating on conventional business logic?
