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 inefficiencies of traditional call center management, where simple first-come-first-served or static skill-based rules fail to optimally match incoming calls with the best available agents, particularly in complex environments with multi-skilled agents (’420 Patent, col. 2:26-42).
• The Patented Solution: The invention proposes a system that treats the matching of a "first entity" (e.g., a caller) to a "second entity" (e.g., an agent) as an economic auction (’420 Patent, Fig. 6). It defines "inferential targeting parameters" for the first entity and "characteristic parameters" for the second, and then performs an "automated optimization" that considers the "economic surplus" of a potential match and the "opportunity cost" of making that agent unavailable for other potential matches (’420 Patent, Abstract).
• Technical Importance: This approach allows for a more dynamic and globally optimized allocation of resources than conventional routing systems by applying economic principles to telecommunications management (’420 Patent, col. 18:41-47).

Key Claims at a Glance

• The complaint alleges infringement of "one or more claims" and "exemplary method claims" but does not specify any independent or dependent claims asserted (Compl. ¶15). The complaint incorporates by reference an external exhibit purported to contain this information, but the exhibit was not filed with the pleading (Compl. ¶17-18).

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 technical problems of "under-skilled" and "over-skilled" agents in call centers, where conventional routing systems either connect a caller to an agent who cannot solve their problem or assign a highly trained specialist to a simple task, leading to inefficiency (’748 Patent, col. 4:35-50).
• The Patented Solution: The invention is a communications routing system that models both communication sources (e.g., callers) and targets (e.g., agents) based on their predicted characteristics and an associated "economic utility" (’748 Patent, Abstract). The system then determines an optimal routing by executing an algorithm designed to maximize the "aggregate utility" of all potential matches, as depicted in flowcharts that optimize a "cost-utility function" (’748 Patent, Fig. 1).
• Technical Importance: The technology moves beyond static routing rules by implementing a cost-utility framework that can factor in variables such as agent training needs and anticipated business outcomes to achieve more efficient long-term call center operation (’748 Patent, col. 24:28-40).

Key Claims at a Glance

• The complaint alleges infringement of "one or more claims" but does not identify any specific claims asserted (Compl. ¶21). It refers to an external exhibit that was not filed with the complaint for these details (Compl. ¶26-27).

U.S. Patent No. 7,023,979 - Telephony control system with intelligent call routing

Issued: April 4, 2006

Technology Synopsis

This patent addresses the inefficiencies of conventional call routing systems (’979 Patent, col. 1:45-56). It proposes a telephony control system that uses a "cost-utility function" to optimize the matching of callers to agents, considering factors beyond simple first-in-first-out processing to improve overall call center performance (’979 Patent, col. 2:1-13).

Asserted Claims

The complaint does not specify which claims are asserted, instead referencing an external exhibit (Exhibit 8) not filed with the pleading (Compl. ¶30, ¶32).

Accused Features

The complaint accuses unspecified "Exemplary Defendant Products" of practicing the claimed technology (Compl. ¶30).

U.S. Patent No. 7,269,253 - Telephony control system with intelligent call routing

Issued: September 11, 2007

Technology Synopsis

This patent, like the related ’979 Patent, describes a system for intelligent call routing in a telephony environment (’253 Patent, col. 1:45-56). The invention provides a method for optimizing call routing by evaluating a cost-utility function that accounts for various agent and caller characteristics, thereby enabling more efficient resource allocation than traditional systems (’253 Patent, col. 2:1-13).

Asserted Claims

The complaint does not identify any asserted claims, referring to an external exhibit (Exhibit 9) that was not filed (Compl. ¶36, ¶38).

Accused Features

The complaint accuses unspecified "Exemplary Defendant Products" of infringement (Compl. ¶36).

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 entities by framing the interaction as an auction (’086 Patent, Abstract). The system defines targeting and characteristic parameters for the entities and performs an "automated optimization" based on the "economic surplus" of a match and the "opportunity cost" of resource unavailability, moving beyond simple rule-based matching (’086 Patent, col. 2:26-42).

Asserted Claims

The complaint does not identify any asserted claims and refers to an external, unfiled exhibit (Exhibit 10) for this information (Compl. ¶42, ¶47).

Accused Features

The complaint accuses unspecified "Exemplary Defendant Products" of infringement (Compl. ¶42).

III. The Accused Instrumentality

Product Identification

The complaint does not identify any specific accused products, methods, or services by name. It refers generally to "Exemplary Defendant Products" that are purportedly detailed in external exhibits which were not filed with the complaint (Compl. ¶15, ¶21, ¶30, ¶36, ¶42).

Functionality and Market Context

The complaint provides no description of the functionality, operation, or market context of any accused instrumentality.

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint alleges direct infringement of the ’420 and ’748 Patents but provides no narrative infringement theory in the body of the pleading. Instead, for each patent, it incorporates by reference a claim chart exhibit (Exhibit 6 for the ’420 Patent; Exhibit 7 for the ’748 Patent) that was not filed with the court (Compl. ¶17-18, ¶26-27). As a result, a detailed analysis of the infringement allegations is not possible based on the provided documents.

V. Key Claim Terms for Construction

As the complaint does not identify the specific claims asserted from the ’420 Patent or the ’748 Patent, an analysis of key claim terms for construction is not possible.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement of infringement for the ’748 and ’086 patents. The allegations are based on Defendant’s distribution of "product literature and website materials" that allegedly instruct and encourage end users to operate the accused products in an infringing manner (Compl. ¶24-25, ¶45-46).
• Willful Infringement: The complaint alleges that Defendant possessed "actual knowledge" of its infringement of the ’748 and ’086 patents at least from the date of service of the complaint and its associated claim charts (Compl. ¶23, ¶44). This forms a basis for allegations of post-suit willful infringement only, as no pre-suit knowledge is alleged.

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

The analysis of this case is defined by the complaint's lack of specific factual allegations, which raises several threshold questions for the court.

• A primary issue will be one of pleading sufficiency: does the complaint, which contains only general allegations of infringement and relies entirely on incorporating external exhibits that were not filed, provide plausible factual support sufficient to state a claim under the standards established by Twombly and Iqbal?
• A central evidentiary question will be one of technical specificity: assuming the case proceeds, what specific evidence will demonstrate that Defendant's healthcare communication systems perform the claimed "automated optimization" and "economic utility" calculations, as distinct from conventional, non-infringing methods of skill-based or priority-based call routing?
• A key question of claim scope may arise regarding the applicability of patent claims directed to "auctions" and "economic surplus" to the operational context of a healthcare provider's patient service and communication systems. The dispute may turn on whether routine call routing activities can be properly characterized as the complex economic optimizations claimed in the patents.
