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”

• Patent Identification: U.S. Patent No. 10,237,420, titled “Method and system for matching entities in an auction,” issued March 19, 2019 (’420 Patent).

The Invention Explained

• Problem Addressed: The patent’s background section describes the inefficiencies in traditional call centers, where Automatic Call Distribution (ACD) systems use simplistic methods like first-come-first-served or static "queue/team" models to route calls (Compl. ¶9; ’420 Patent, col. 2:26-67). These approaches fail to optimally match callers with agents who have the right skills, leading to problems like routing calls to under-skilled or over-skilled agents, which reduces transactional throughput (’420 Patent, col. 4:35-61).
• 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., an agent) as an auction (’420 Patent, Abstract). The system performs an "automated optimization" that considers not only the best match based on skills but also the "economic surplus" of that match and the "opportunity cost" of making that agent unavailable for other potential callers (’420 Patent, Abstract; col. 24:42-50). This allows for a more dynamic and globally optimized routing decision than prior art systems.
• Technical Importance: This approach represents a shift from static, rule-based call routing to a dynamic, economic model that can globally optimize resource allocation in real-time, a significant goal for enhancing the efficiency of large-scale communication centers (’420 Patent, col. 21:1-8).

Key Claims at a Glance

• The complaint does not identify specific claims, instead referring to "exemplary claims" in an exhibit that was not filed with the complaint (Compl. ¶¶15, 17). Claim 1 is the first independent claim.
• Claim 1 includes these essential elements:
  • Defining a plurality of multivalued scalar data representing inferential targeting parameters for the 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.
  • The optimization also considers an opportunity cost of the unavailability of the second entity for matching with an alternate first entity.

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

• Patent Identification: U.S. Patent No. 10,491,748, titled “Intelligent communication routing system and method,” issued November 26, 2019 (’748 Patent).

The Invention Explained

• Problem Addressed: The patent addresses the same technical problem as the ’420 Patent: the limitations of traditional, non-optimized call routing systems in complex, multi-skilled call center environments (Compl. ¶10; ’748 Patent, col. 2:26-67).
• The Patented Solution: The invention is a communications routing system that determines an optimal routing path between communication sources and targets by "maximizing an aggregate utility" (’748 Patent, Abstract). Instead of just connecting the next available agent, the system considers the predicted characteristics and economic utility of both the communication source (e.g., caller) and potential targets (e.g., agents) to find the match that provides the greatest overall value to the system (’748 Patent, col. 24:28-41).
• Technical Importance: The technology provides a framework for intelligent, value-based routing that accounts for long-term operational goals, such as agent training, rather than just immediate transactional efficiency (’748 Patent, col. 27:8-14).

Key Claims at a Glance

• The complaint does not identify specific claims, instead referring to "exemplary claims" in an un-filed exhibit (Compl. ¶¶21, 26). Claim 1 is the first independent claim.
• Claim 1 includes these essential elements:
  • 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.

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

• Patent Identification: U.S. Patent No. 7,023,979, titled “Telephony control system with intelligent call routing,” issued April 4, 2006 (’979 Patent).
• Technology Synopsis: The patent describes a communications management system with an input for receiving a communication classification, a database of agent skill scores, and a processor for computing an optimum agent selection based on the received classification (’979 Patent, Abstract). The system is designed to directly control the routing of the communication based on this intelligent selection.
• Asserted Claims: The complaint asserts infringement of "one or more claims" (Compl. ¶30).
• Accused Features: The "Exemplary Defendant Products" are accused 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, titled “Telephony control system with intelligent call routing,” issued September 11, 2007 (’253 Patent).
• Technology Synopsis: This patent, which shares a specification with the ’979 Patent, claims a method for remediating discrimination in agent selection by comparing performance metrics of subgroups and defining a remediation mode. The system uses a cost-benefit analysis to allocate opportunities and offset inferior performance during remediation.
• Asserted Claims: The complaint asserts infringement of "one or more claims" (Compl. ¶39).
• Accused Features: The "Exemplary Defendant Products" are accused of infringing the patent (Compl. ¶39).

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

• Patent Identification: U.S. Patent No. 9,456,086, titled “Method and system for matching entities in an auction,” issued September 27, 2016 (’086 Patent).
• Technology Synopsis: Sharing a specification with the ’420 Patent, this invention describes a method for matching entities by defining scalar data for inferential targeting parameters and characteristics. It then performs an automated optimization based on the economic surplus of a match and the opportunity cost of that entity's unavailability for other matches.
• Asserted Claims: The complaint asserts infringement of "one or more claims" (Compl. ¶45).
• Accused Features: The "Exemplary Defendant Products" are accused of infringing the patent (Compl. ¶45).

III. The Accused Instrumentality

Product Identification

• The complaint does not specifically identify any accused products or services by name in the body of the complaint. It repeatedly refers to "Exemplary Defendant Products" that are purportedly identified in Exhibits 6 through 10 (Compl. ¶¶15, 21, 30, 39, 45). However, these exhibits were not filed with the complaint.

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the accused instrumentality's functionality. Based on the asserted patents and the nature of the Defendant’s business as a hotel corporation, the accused instrumentalities are presumably systems related to customer service, communications, and/or reservations that involve matching customer inquiries with internal resources (Compl. ¶¶15-16). The complaint alleges that Defendant makes, uses, sells, and internally tests these products (Compl. ¶¶15-16, 21-22).

IV. Analysis of Infringement Allegations

The complaint alleges that infringement is detailed in claim charts included as Exhibits 6-10, which were incorporated by reference but not filed with the court (Compl. ¶¶17-18, 26-27, 35-36, 41-42, 50-51). In the absence of these exhibits, the complaint’s narrative theory is that the "Exemplary Defendant Products" practice the technology claimed in the Patents-in-Suit and satisfy all elements of the asserted claims (Compl. ¶¶17, 26). The complaint offers no specific, element-by-element factual allegations in the pleading itself to support this conclusion.

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Pleading Sufficiency Question: A foundational issue for the court will be whether the complaint's incorporation by reference of exhibits that were not filed provides sufficient factual detail to state a plausible claim for relief and give the Defendant fair notice of the infringement allegations.
  • Scope Questions: A central dispute may arise over whether the terminology used in the patents, which is heavily rooted in the context of call centers and agent routing (e.g., ’420 Patent, col. 2:26-34), can be construed to apply to the Defendant's hospitality and reservation systems. For example, a question for the court may be whether matching a guest with a hotel room constitutes the claimed "automated optimization with respect to an economic surplus" (’420 Patent, Abstract).
  • Technical Questions: Without the claim charts, it is unclear what specific functions of the Defendant’s systems are accused of performing the claimed optimization steps. A key technical question will be whether the accused systems perform a dynamic, multi-factorial optimization as claimed, or if they operate based on a more conventional set of predetermined, static rules.

V. Key Claim Terms for Construction

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

• Context and Importance: This term appears to be at the core of the inventive concept of the ’420 and ’086 Patents. The outcome of the infringement analysis may depend on whether the Defendant's system calculates anything that can be characterized as an "economic surplus" when matching entities. Practitioners may focus on whether this requires a specific monetary calculation or can encompass a more abstract measure of value.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification discusses the concept in terms of "optimizing a cost-utility function" and achieving "business goals," which could include non-monetary factors like "customer satisfaction" (’420 Patent, col. 24:31-39). This may support a broader construction that is not limited to a literal financial surplus.
  • Evidence for a Narrower Interpretation: The patent frequently uses economic language, such as "cost function normalized in economic units" and parameters like "sales volume, profit, or the like" (’420 Patent, col. 24:35-38), which may support a narrower construction requiring a calculation grounded in financial or quasi-financial metrics.

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

• Context and Importance: This term is central to the optimization process claimed in the ’748 Patent. The dispute will likely focus on whether the accused system performs a true "maximization" process across an "aggregate" of potential outcomes, or if it simply applies a sequential set of rules to find a single acceptable match.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent abstract speaks of maximizing utility with respect to "predicted characteristics," which could be interpreted broadly to cover any system that selects a preferred outcome based on multiple weighted factors (’748 Patent, Abstract).
  • Evidence for a Narrower Interpretation: The specification discusses a "global optimization" that considers the impact of a single routing decision on the entire system, weighing competing requests and opportunity costs (’748 Patent, col. 24:53-65). This language may support a narrower construction requiring a holistic, system-wide calculation rather than a localized, greedy-algorithm approach.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for the ’748, ’979, and ’086 Patents. The basis for inducement is the allegation that Defendant distributes "product literature and website materials" that instruct end users on how to use the accused products in an infringing manner (Compl. ¶¶24, 33, 48).
• Willful Infringement: While the complaint does not use the term "willful," it alleges that service of the complaint constitutes "actual knowledge" of infringement for the ’748, ’979, and ’086 Patents and that Defendant's infringement has continued post-filing (Compl. ¶¶23-25, 32-34, 47-49). These allegations may form the basis for a claim of post-filing willful infringement.

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

• A threshold legal issue will be one of pleading sufficiency: does the complaint, which premises its technical infringement allegations entirely on exhibits that were not filed with the court, satisfy the pleading standards under Twombly and Iqbal by providing the Defendant with fair notice of the claims against it?
• A central technical question will be one of analogical scope: can the patent claims, which describe sophisticated optimization algorithms in the context of routing communications to service agents in a call center, be construed to cover the functionalities of a hotel corporation’s customer reservation or service systems?
• A key evidentiary question will be one of operational function: assuming the complaint proceeds, discovery will focus on whether the accused systems actually perform the dynamic, multi-factorial optimization required by the claims (e.g., maximizing utility or calculating economic surplus), or if they operate on a set of static, predetermined rules that fall outside the claims' scope.
