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"

The Invention Explained

• Problem Addressed: The patent describes the challenge of efficiently managing call centers, which must balance providing high-quality customer service with the costs of staffing agents who have varying skill sets (’420 Patent, col. 2:26-34). Traditional systems can lead to inefficient outcomes, such as routing a call to an under-skilled agent who cannot resolve the issue or an over-skilled agent whose expertise is wasted on a simple query (’420 Patent, col. 4:35-64).
• The Patented Solution: The invention proposes a system for intelligently routing communications by performing a "multifactorial optimization" to match a "first entity" (e.g., a caller) with the best "second entity" (e.g., an agent) from a pool of available options (’420 Patent, col. 18:9-24). As illustrated in Figure 1, this process moves beyond simple queuing to consider complex variables, optimizing for factors like cost, utility, and agent skills to make the best match in real-time (’420 Patent, Fig. 1; col. 24:39-50).
• Technical Importance: This technology aims to replace static, first-in-first-out call distribution models with dynamic, intelligent routing that can adapt to changing conditions and optimize for long-term business goals, such as agent training and overall efficiency (’420 Patent, col. 27:9-14).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, instead incorporating an unattached exhibit by reference (Compl. ¶15). For the purposes of analysis, representative independent Claim 1 is examined.
• Claim 1 of the ’420 Patent recites a method with 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 for each of a plurality of second entities, representing their characteristic parameters.
  • Performing an automated optimization with respect to an economic surplus of a match between the first entity and one of the second entities.
  • The optimization also considers an opportunity cost related to the unavailability of the selected second entity for matching with an alternate first entity.
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 8,831,205 - "Intelligent communication routing"

The Invention Explained

• Problem Addressed: The patent’s background section identifies the same core problem as the ’420 Patent: the inefficiency of traditional Automatic Call Distribution (ACD) systems in modern call centers, where agents have diverse skills and call types are varied (’205 Patent, col. 2:30-col. 3:2). These systems struggle to make optimal routing decisions, leading to poor resource allocation.
• The Patented Solution: The invention describes a communications routing system that contextually analyzes a communication and executes a "targeting algorithm" to determine an "optimum target" from a plurality of available destinations (’205 Patent, Abstract). The system integrates this intelligent decision-making at a low level within the communications architecture, allowing it to evaluate complex criteria in real-time to direct the communication appropriately, as depicted in the flowchart of Figure 1 (’205 Patent, Fig. 1; col. 36:8-14).
• Technical Importance: The solution aims to improve upon prior art systems by embedding the intelligence for routing decisions within the low-level communications server itself, which may reduce latency and allow for more sophisticated, real-time optimization compared to systems that externalize this analysis to a high-level management system (’205 Patent, col. 35:9-14).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, instead incorporating an unattached exhibit by reference (Compl. ¶21). For the purposes of analysis, representative independent Claim 1 is examined.
• Claim 1 of the ’205 Patent recites a system with the following essential elements:
  • A router adapted to receive a communication comprising data over a network and route it to one of a plurality of available destinations.
  • The router automatically executes a communication targeting algorithm based on the data.
  • The algorithm operates to contextually and jointly analyze a plurality of parameters from the data and a plurality of contextual parameters.
  • The algorithm determines an optimum target, which varies in dependence on both the data and the context.
  • The router routes the communication based on the algorithm's execution.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

• The complaint does not identify the accused products or services by name, referring to them generally as "Exemplary Defendant Products" (Compl. ¶12, ¶18).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the functionality or market context of the accused instrumentality. It makes no factual assertions about how any of Defendant's products operate, alleging only that unattached exhibits set forth how they "practice the technology claimed" (Compl. ¶14, ¶20). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint does not provide a narrative infringement theory or substantive factual allegations, instead incorporating by reference claim charts from unattached exhibits (Compl. ¶15, ¶21). The complaint alleges that these charts demonstrate that the "Exemplary Defendant Products" practice the claimed technology and satisfy all elements of the asserted claims (Compl. ¶14, ¶20). As no substantive allegations or evidence are provided in the complaint itself, a claim chart summary cannot be constructed.

• Identified Points of Contention:
  • Scope Questions: The patents-in-suit are described extensively in the context of telecommunications, call centers, and agent-matching auctions. A primary legal question will be one of claim scope: whether the claims, interpreted in light of their specifications, can be construed to read on the functionalities of a visual discovery and social media platform, which is Defendant’s line of business. The dispute may center on whether abstract terms like "entity," "communication," and "router" are limited by the patents' detailed descriptions of call-center embodiments.
  • Technical Questions: Given the complaint's lack of specificity, a central evidentiary question will be what specific features of the Defendant’s platform are alleged to perform the claimed functions. For example, the case may raise the question of what evidence Plaintiff will offer to show that Defendant’s platform performs an "automated optimization with respect to an economic surplus" (’420 Patent, Claim 1) or executes a "communication targeting algorithm" that "contextually jointly analyze[s]" parameters to find an "optimum target" (’205 Patent, Claim 1).

V. Key Claim Terms for Construction

• The Term: "matching a first entity with at least one second entity" (’420 Patent, Claim 1)
• Context and Importance: This term is critical because the infringement analysis will depend on whether the defendant's system, which connects users with visual content ("pins") and other users, performs a "matching" of "entities" within the meaning of the patent. Practitioners may focus on this term because its construction will determine whether the patent's scope can extend beyond the call-center context to the social media context.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself is abstract, using the general terms "first entity" and "second entity" without explicitly limiting them to "callers" and "agents."
  • Evidence for a Narrower Interpretation: The specification consistently describes the invention in the context of a call center, where the "first entity" is a customer and the "second entity" is an agent or other resource (’420 Patent, col. 2:26-34). The detailed description of the problem and solution is framed almost entirely around this specific embodiment.
• The Term: "communication" (’205 Patent, Claim 1)
• Context and Importance: The viability of the infringement claim against a social media platform will likely turn on the definition of "communication." The patent specification heavily implies voice telephony. The question will be whether data transfers, such as a user saving a "pin" or following another user's board, constitute a "communication" as contemplated by the patent.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The term "communication" is not explicitly limited to voice in the claim language itself, and could be argued to encompass any data transmission over a network.
  • Evidence for a Narrower Interpretation: The patent’s background and detailed description sections are replete with terminology specific to telephony, such as "call center," "telephone," "Automatic Call Distribution (ACD)," and "call routing," suggesting the term was understood in that context (’205 Patent, col. 2:30-col. 3:2).

VI. Other Allegations

• Willful Infringement: The complaint does not include an explicit count for willful infringement or allege any facts that would support a finding of willfulness, such as pre-suit knowledge of the patents. The prayer for relief requests damages under 35 U.S.C. § 284 and a declaration that the case is "exceptional" under 35 U.S.C. § 285, but provides no factual predicate for these requests in the body of the complaint (Compl. Prayer ¶F, G(i)).

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

• A core issue will be one of technological applicability and definitional scope: can claim terms rooted in the technical context of call center optimization and telecommunications auctions, such as "matching entities" and "communication routing," be construed broadly enough to cover the alleged functionalities of a visual-based social media platform? The outcome may depend on whether the court finds the claims are limited to the specific embodiments detailed in the specifications.
• A key procedural question will be one of pleading sufficiency: does the complaint, which contains no substantive factual allegations of infringement and relies entirely on incorporating unattached exhibits by reference, meet the plausibility standard required by Federal Rule of Civil Procedure 8 as interpreted by the Supreme Court in Bell Atlantic Corp. v. Twombly and Ashcroft v. Iqbal?
