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 (Method and system for matching entities in an auction), issued March 19, 2019.
• The Invention Explained:
  • Problem Addressed: The patent’s background section describes the inefficiency of traditional call center management strategies, where routing inbound calls to agents based on simple rules like "first-come-first-served" or "longest-idle-agent" fails to account for varying agent skills and differing call types, leading to suboptimal performance ('420 Patent, col. 2:42-col. 4:67).
  • The Patented Solution: The invention proposes a system that treats call routing as an auction. It matches a "first entity" (e.g., a caller) with one of many "second entities" (e.g., agents) by defining descriptive data for each and then performing an "automated optimization." This optimization considers not just a direct match, but also the "economic surplus" of a potential pairing and the "opportunity cost" of making a particular agent unavailable for other potential matches ('420 Patent, Abstract). The system aims to find the most economically efficient pairing in a dynamic environment ('420 Patent, col. 1:57-67).
  • Technical Importance: This approach represents a shift from simple queuing logic to a market-based mechanism for allocating communication resources, enabling optimizations based on complex business goals rather than just operational metrics ('420 Patent, col. 21:1-22:50).
• Key Claims at a Glance:
  • The complaint does not identify specific asserted claims, instead incorporating by reference claim charts from an unprovided "Exhibit 8" (Compl. ¶¶17, 19). For analytical purposes, independent claim 1 is representative.
  • The essential elements of independent claim 1 include:
    • Defining multivalued scalar data representing "inferential targeting parameters" for a first entity.
    • Defining multivalued scalar data representing "characteristic parameters" for each of a plurality of second entities.
    • Performing an automated optimization that considers both an "economic surplus" of a match and the "opportunity cost" of making a second entity unavailable for an alternate match.

U.S. Patent No. 10,491,748: Intelligent communication routing system and method

• Patent Identification: 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 challenge of optimizing call center operations for both short-term efficiency (e.g., handling a call quickly) and long-term goals (e.g., agent training), a trade-off that simple routing systems cannot manage effectively ('748 Patent, col. 27:8-21).
  • The Patented Solution: The invention describes a routing system that determines an optimal routing path by "maximizing an aggregate utility" ('748 Patent, Abstract). This utility function can incorporate both short-term performance metrics and long-term objectives, such as valuing a call as a training opportunity ('748 Patent, Fig. 1, 311-312). The system represents callers and agents with predicted characteristics and uses these representations to calculate the optimal pairing based on the defined utility function ('748 Patent, Abstract).
  • Technical Importance: The invention provides a formal framework for balancing competing business objectives (e.g., immediate productivity versus workforce development) within a communication routing system ('748 Patent, col. 27:8-32).
• Key Claims at a Glance:
  • The complaint does not identify specific asserted claims, instead incorporating by reference claim charts from an unprovided "Exhibit 9" (Compl. ¶¶23, 28). For analytical purposes, independent claim 1 is representative.
  • The essential elements of independent claim 1 include:
    • 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" based on the predicted characteristics.

Multi-Patent Capsules

• U.S. Patent No. 7,023,979 (Telephony control system with intelligent call routing), issued April 4, 2006: This patent describes a system for routing calls to agents by analyzing caller and agent characteristics to optimize a cost-utility function, considering factors beyond simple call queuing (Compl. ¶11). The complaint asserts infringement by Defendant's products but refers to an unprovided exhibit for specific claims and accused features (Compl. ¶¶32, 37).
• U.S. Patent No. 7,269,253 (Telephony control system with intelligent call routing), issued September 11, 2007: This patent relates to similar technology as the ’979 Patent, focusing on intelligent call routing based on optimizing agent selection (Compl. ¶12). The complaint's infringement allegations refer to an unprovided exhibit for details (Compl. ¶¶41, 43).
• U.S. Patent No. 8,275,413 (Wireless communication device with integrated electromagnetic radiation sensors), issued September 25, 2012: This patent addresses a mobile device incorporating sensors for detecting external electromagnetic radiation, such as infrared sensors for non-contact temperature measurement (Compl. ¶13). The complaint alleges infringement by sensor-equipped OnePlus products, with details contained in an unprovided exhibit (Compl. ¶¶47, 52).
• U.S. Patent No. 8,825,112 (Mobile communication device with electromagnetic radiation sensors), issued September 2, 2014: This patent is related to the ’413 Patent and concerns mobile devices with integrated electromagnetic radiation sensors (Compl. ¶14). Infringement allegations against OnePlus products' sensor functionalities are detailed in an unprovided exhibit (Compl. ¶¶56, 58).
• U.S. Patent No. 9,456,086 (Method and system for matching entities in an auction), issued September 27, 2016: This patent is related to the ’420 Patent and describes a method for matching entities through an auction-based system that considers economic factors (Compl. ¶15). The complaint alleges infringement by OnePlus products but incorporates an unprovided exhibit for details (Compl. ¶¶62, 67).

III. The Accused Instrumentality

• Product Identification: The complaint names "Exemplary Defendant Products" as the accused instrumentalities (Compl. ¶17).
• Functionality and Market Context: The complaint does not describe the specific functionality of the accused products. Instead, for each count of infringement, it incorporates by reference external exhibits (Exhibits 8-14) which are not attached to the complaint (Compl. ¶¶19, 28, 37, 43, 52, 58, 67). These exhibits allegedly contain charts comparing the asserted patent claims to the accused products. As such, the complaint itself provides no substantive description of the accused instrumentality's technical operation or market context.

IV. Analysis of Infringement Allegations

The complaint does not provide sufficient detail for analysis of infringement allegations. For each of the seven asserted patents, the complaint makes conclusory statements that the Defendant infringes and states that the details are "set forth in" and "incorporated by reference" from external exhibits (Exhibits 8, 9, 10, 11, 12, 13, and 14, respectively) (Compl. ¶¶19, 28, 37, 43, 52, 58, 67). Because these exhibits were not filed with the complaint, there is no factual basis within the provided document to construct a claim chart or analyze the specifics of the infringement allegations.

V. Key Claim Terms for Construction

• The Term: "automated optimization with respect to an economic surplus ... and an opportunity cost" (from the ’420 Patent).

• Context and Importance: This composite term forms the core of the inventive concept in the auction-based routing patents. The case may turn on whether the accused functionality performs a true "optimization" that calculates and balances both "economic surplus" and "opportunity cost," or if it employs a simpler heuristic that does not meet this claim limitation.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification describes the invention in general terms applicable to various "computer integrated telecommunications systems" ('420 Patent, col. 1:19-22), which may support a construction not strictly limited to the call-center examples.
  • Evidence for a Narrower Interpretation: The detailed description is heavily focused on the specific problems of call centers, using terms like "agents," "call types," and "cost-utility function" in that context ('420 Patent, col. 2:25-col. 4:67). This extensive focus on a particular embodiment could be used to argue for a narrower construction of the optimization elements.

• The Term: "maximizing an aggregate utility" (from the ’748 Patent).

• Context and Importance: This term is central to defining the claimed method. The dispute will likely focus on what level of computational complexity is required to satisfy "maximizing." Practitioners may focus on whether a simple rule-based selection process qualifies, or if a more rigorous mathematical optimization is required.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The term "utility" is broad, and the specification notes it can include non-economic factors like "customer satisfaction," suggesting it is not limited to a purely financial calculation ('748 Patent, col. 24:37-40).
  • Evidence for a Narrower Interpretation: The specification provides a detailed mathematical formula representing the utility calculation, including multiple distinct cost and value terms (e.g., An=Max({[Acn1∑(rs₁ans₁)+Acn2]+Bcn}+Ccn)+Dcn>) ('748 Patent, col. 24:51-53). A defendant could argue this explicit formula defines and narrows what the patent means by "maximizing an aggregate utility."

VI. Other Allegations

• Indirect Infringement: For the ’748, ’979, ’413, and ’086 Patents, the complaint alleges induced infringement based on Defendant's knowledge acquired "at least since being served by this Complaint" (Compl. ¶¶27, 36, 51, 66). The alleged inducing acts include selling products and distributing "product literature and website materials" that allegedly direct end users to infringe (Compl. ¶¶26, 35, 50, 65).
• Willful Infringement: The complaint does not contain a separate count for willful infringement. However, for four of the seven patents, it alleges that Defendant gained "actual knowledge" of infringement upon service of the complaint and "has and continues to" infringe despite this knowledge (Compl. ¶¶25, 34, 49, 64). These allegations may form the basis for a claim of post-filing willfulness.

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

• A central evidentiary issue will be one of factual sufficiency: The complaint's infringement theory rests entirely on seven external exhibits that were not filed with the court. A key question is whether Plaintiff can produce sufficient factual evidence to substantiate its conclusory allegations and map the complex, multi-element claims onto the specific operation of the accused OnePlus products.
• A core legal issue will be one of definitional scope: The case will likely hinge on the construction of terms like "automated optimization," "economic surplus," and "maximizing an aggregate utility." A critical question for the court will be whether these terms, rooted in the patent specifications' detailed descriptions of complex call center environments, can be construed broadly enough to read on the functionality of a consumer smartphone.
• A key technical question will be one of operational equivalence: The dispute will likely examine whether the accused features in OnePlus devices perform the specific, multi-factorial, and economically-driven optimizations required by the asserted claims, or if there is a fundamental mismatch between the patented methods and the actual technical operation of the accused products.
