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 Mar. 19, 2019)

The Invention Explained

• Problem Addressed: The patent's background describes the inefficiencies of traditional call center management, which often uses simple queuing logic (e.g., first-come-first-served) or static skill-based routing. These methods can lead to mismatches, such as routing a complex call to an under-skilled agent or a simple call to an over-skilled agent, reducing overall throughput. (’420 Patent, col. 4:35-61).
• The Patented Solution: The invention proposes a system that treats the matching of an incoming communication (a "first entity") to an available agent (a "second entity") as an auction. The system performs a "multifactorial optimization" that considers not only the skill-based fit but also an "economic surplus" of the match and the "opportunity cost" of making that agent unavailable for other potential matches. (’420 Patent, Abstract; col. 15:35-50). This allows for a more dynamic and economically efficient allocation of call center resources.
• Technical Importance: This approach represents a shift from static routing rules to a dynamic, holistic optimization that can adapt to changing call volumes and agent availability to maximize a defined business objective, such as efficiency or profitability. (Compl. ¶ 9; ’420 Patent, col. 6:10-25).

Key Claims at a Glance

• The complaint asserts one or more claims of the ’420 Patent, incorporating claim charts by reference that were not filed with the complaint (Compl. ¶¶ 15, 17-18). Independent claim 1 is representative.
• Claim 1 Elements:
  • A method for matching a first entity with at least one second entity 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 their characteristic parameters.
  • 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 matched second entity for an alternate first entity.

U.S. Patent No. 10,491,748 - Intelligent communication routing system and method (Issued Nov. 26, 2019)

The Invention Explained

• Problem Addressed: The patent addresses the same technical problem as the ’420 Patent: the limitations of traditional call center routing systems in efficiently matching callers to agents with the appropriate skills. (’748 Patent, col. 2:25-34).
• The Patented Solution: The invention describes a routing system that determines an optimal routing path by representing both communication sources (e.g., callers) and communication targets (e.g., agents) with "predicted characteristics," each having an "economic utility." The system then seeks to maximize an "aggregate utility" based on these characteristics, effectively performing a cost-benefit analysis for each potential match. (’748 Patent, Abstract; col. 24:40-50).
• Technical Importance: This method allows a communication system to make routing decisions based on a calculated, aggregate economic value rather than a single, static rule, which could improve the overall business performance of a call center. (Compl. ¶ 10; ’748 Patent, col. 24:28-39).

Key Claims at a Glance

• The complaint asserts one or more claims of the ’748 Patent, incorporating claim charts by reference that were not filed with the complaint (Compl. ¶¶ 21, 26-27). Independent claim 1 is representative.

• Claim 1 Elements:

  • A communications routing method.
  • Representing a plurality of predicted characteristics of a plurality of communications sources, each having an economic utility.
  • Representing a plurality of 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 their respective predicted characteristics.

  • Accused Features: The "Exemplary Defendant Products" (Compl. ¶ 45).

III. The Accused Instrumentality

Product Identification

The complaint identifies the accused instrumentalities as the "Exemplary Defendant Products" (Compl. ¶ 15).

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the accused instrumentality's specific features. It alleges that these products are identified in claim chart exhibits attached to the complaint; however, those exhibits were not filed with the public docket (Compl. ¶¶ 17, 26, 35, 41, 50). Based on the defendant’s name, "Healthcare Highways, LLC," the accused instrumentalities may relate to healthcare plan administration, patient services, or provider network management systems that involve routing customer or provider communications. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint alleges infringement but incorporates by reference claim chart Exhibits 6, 7, 8, 9, and 10, which were not filed with the complaint (Compl. ¶¶ 18, 27, 36, 42, 51). The complaint’s narrative allegations are conclusory, stating that the accused products "practice the technology claimed" and "satisfy all elements" of the exemplary claims without providing specific factual support for how any specific feature of any product meets any specific claim limitation (Compl. ¶¶ 17, 26, 35, 41, 50).

Identified Points of Contention

• Scope Questions: A central dispute may arise over whether the defendant's system, which likely routes healthcare-related inquiries, can be said to perform an "auction" as that term is used in the ’420 and ’086 Patents. The interpretation of "economic surplus" and "economic utility" will also be critical, raising the question of whether metrics like patient satisfaction or efficiency in resolving insurance queries can be construed as the economic factors described in the patents.
• Technical Questions: A key factual question will be whether the accused products perform the claimed "multifactorial optimization." The defendant may argue its systems use conventional, rule-based routing, raising the question of what evidence the plaintiff can produce to show that the accused systems actually execute the complex, cost-benefit optimization algorithms required by the claims.

V. Key Claim Terms for Construction

The Term: "matching entities in an auction" (’420 Patent, Claim 1)

Context and Importance

This phrase is central to the patent’s framing of its invention and distinguishes it from conventional routing. Practitioners may focus on this term because its construction will determine whether the claim is limited to systems with explicit bidding mechanisms or can be read more broadly to cover any algorithmic selection process.

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: The specification describes routing communications "based on the results of an auction which is sensitive to both economic factors and non-economic factors," which could be argued to describe any system that weighs multiple variables to find an optimal match, not just a literal auction. (’420 Patent, col. 11:50-54).
• Evidence for a Narrower Interpretation: The detailed description repeatedly uses auction-specific terminology, such as agents "bidding for a caller" on a commission basis, which may support an interpretation that requires some form of competitive bidding process. (’420 Patent, col. 22:50-56).

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

Context and Importance

The determination of an "optimal routing" is explicitly tied to maximizing an "aggregate utility" derived from the "economic utility" of sources and targets. The definition of this term will be critical to determining whether the accused system performs the claimed optimization.

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: The specification suggests that business goals like "customer satisfaction" can be "converted and normalized into economic terms," which may support a broad definition of "economic utility" that includes non-monetary performance metrics. (’748 Patent, col. 24:36-40).
• Evidence for a Narrower Interpretation: The specification also provides concrete economic examples, such as calculating agent cost by dividing "daily salary by the average number of calls per day," which could support a narrower construction requiring a direct link to financial or cost-based metrics. (’748 Patent, col. 24:1-5).

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement for the ’748, ’979, and ’086 Patents. The allegations are based on the defendant allegedly distributing "product literature and website materials" that instruct end users to operate the accused products in an infringing manner (Compl. ¶¶ 24, 33, 48). The complaint alleges that knowledge and intent for inducement exist "at least since being served by this Complaint" (Compl. ¶¶ 25, 34, 49).

Willful Infringement

The complaint does not contain an explicit count for willful infringement, but it does request that the case be declared "exceptional" under 35 U.S.C. § 285 (Compl. ¶ N.i). The factual basis for "actual knowledge" is alleged to arise from the service of the complaint itself (Compl. ¶¶ 23, 32, 47).

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

• A core issue will be one of definitional scope: can the patent term "auction," which is central to the framing of several patents-in-suit, be construed to cover the routing of customer inquiries in the defendant's healthcare services platform, or is there a fundamental mismatch in the technological paradigm?
• A key procedural question will be one of pleading sufficiency: does the complaint, which makes conclusory allegations of infringement and incorporates by reference exhibits that were not filed, set forth sufficient factual matter to state a plausible claim for relief under the prevailing Twombly/Iqbal standard?
• A central evidentiary question will be one of technical operation: what evidence can be presented to demonstrate that the accused systems perform the complex, multi-factor "automated optimization" based on "economic utility" as required by the claims, versus a more conventional, non-infringing rules-based routing method?
