II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 11,107,581 - "Senior Living Engagement and Care Support Platforms"

  • Issued: August 31, 2021

The Invention Explained

  • Problem Addressed: The patent background describes conventional systems for coordinating senior care as having drawbacks, such as merely keeping schedules without facilitating senior engagement and often requiring invasive monitoring through cameras or wearable devices (Compl. ¶45).
  • The Patented Solution: The invention is a computer-based “Engagement and Care Support Platform” (“ECSP”) that uses a chatbot to facilitate a senior user’s interactions with the system. The platform is programmed to determine an expected time for a senior to interact with the chatbot and to continuously monitor for that interaction. If the interaction is not detected by the expected time, the system transmits a message to a caregiver, providing a non-intrusive "check-in" mechanism (Compl. ¶69; ’581 Patent, Abstract).
  • Technical Importance: This technology aims to allow seniors to maintain independence while providing remote caregivers insight into their activity levels without requiring manual check-ins or intrusive camera systems (Compl. ¶36).

Key Claims at a Glance

  • The complaint asserts at least independent claim 1 and dependent claim 5 (Compl. ¶68, ¶77).
  • Essential elements of independent claim 1 include:
    • An ECSP computer device comprising a processor, chatbot, and memory, in communication with a first client device (senior user) and a second client device (caregiver).
    • The processor is programmed to store user and caregiver information.
    • The processor is programmed to determine a first expected time of interaction for the senior user with the chatbot.
    • The processor is programmed to continuously monitor for a senior user interaction.
    • In response to not detecting the interaction by the expected time, the processor is programmed to transmit a message to the caregiver's device indicating the lack of interaction.
  • The complaint reserves the right to assert additional claims (Compl. ¶81).

U.S. Patent No. 11,114,203 - "Senior Living Engagement and Care Support Platforms"

  • Issued: September 7, 2021

The Invention Explained

  • Problem Addressed: The problem is consistent with that of the ’581 Patent: providing non-intrusive monitoring for caregivers of seniors who wish to live independently (Compl. ¶45).
  • The Patented Solution: This invention also describes an ECSP with a chatbot. Its distinct feature is monitoring for a second user interaction subsequent to a first one. The system determines the elapsed time between the first interaction and the current time. If this elapsed time exceeds a predetermined threshold without a second interaction occurring, it transmits a message to the caregiver, indicating an unusual period of inactivity (Compl. ¶107; ’203 Patent, Abstract).
  • Technical Importance: This approach provides a more nuanced form of monitoring, capable of detecting abnormal periods of inactivity during the day, rather than just a single missed check-in (Compl. ¶115-116).

Key Claims at a Glance

  • The complaint asserts at least independent claim 1 (Compl. ¶106).
  • Essential elements of independent claim 1 include:
    • An ECSP computer device with a processor, chatbot, and memory, in communication with a senior's and a caregiver's client devices.
    • The processor is programmed to store user and caregiver information.
    • The processor is programmed to continuously monitor for and detect a first senior user interaction.
    • The processor is programmed to continuously monitor for a second senior user interaction subsequent to the first.
    • The processor is programmed to determine an elapsed amount of time between detecting the first interaction and a current time without having detected the second interaction.
    • When the elapsed time exceeds a predetermined threshold, the processor transmits a message to the caregiver.
  • The complaint reserves the right to assert additional claims (Compl. ¶117).

Multi-Patent Capsule: U.S. Patent No. 11,056,235

  • Patent Identification: U.S. Patent No. 11,056,235, "Senior Living Engagement and Care Support Platforms," issued July 6, 2021 (Compl. ¶50).
  • Technology Synopsis: This patent describes an ECSP that monitors for a senior user's interaction with a chatbot relative to a predefined period of time. It is programmed to transmit one message to a caregiver if the interaction is detected before the expected time elapses and a different message if the interaction is not detected by that time (Compl. ¶143).
  • Asserted Claims: At least independent claim 1 (Compl. ¶142).
  • Accused Features: The complaint alleges that Alexa Together’s ability to send alerts for both detected activity and lack of activity infringes this patent (Compl. ¶151, ¶152).

Multi-Patent Capsule: U.S. Patent No. 11,393,585

  • Patent Identification: U.S. Patent No. 11,393,585, "Senior Living Engagement and Care Support Platforms," issued July 19, 2022 (Compl. ¶52).
  • Technology Synopsis: This patent claims a user computer device that determines an expected time of interaction based on a first unprompted and unscheduled verbal interaction from a user. The device then monitors for a subsequent interaction and sends a message to a caregiver if one is detected prior to the expected time (Compl. ¶179).
  • Asserted Claims: At least independent claim 1 (Compl. ¶178).
  • Accused Features: The complaint alleges that Alexa Together’s feature of setting up daily alerts based on a "first Alexa use" infringes this patent (Compl. ¶184, ¶186).

Multi-Patent Capsule: U.S. Patent No. 10,825,318

  • Patent Identification: U.S. Patent No. 10,825,318, "Sensing Peripheral Heuristic Evidence, Reinforcement, and Engagement System," issued November 3, 2020 (Compl. ¶54).
  • Technology Synopsis: This patent claims a method for training a machine learning module to identify abnormalities in sensor data from home environments. The method involves analyzing historical sensor data (e.g., heart rate, movement) and historical condition data (e.g., medical conditions) to identify anomalies and modify the learning module accordingly (Compl. ¶213).
  • Asserted Claims: At least independent claim 1 (Compl. ¶212).
  • Accused Features: The complaint accuses the combination of Alexa Together with third-party fall detection services, such as Vayyar Care, which allegedly uses a "learning mode" to become familiar with an environment by collecting sensor data over time (Compl. ¶209, ¶216, ¶217).

Multi-Patent Capsule: U.S. Patent No. 11,094,180

  • Patent Identification: U.S. Patent No. 11,094,180, "Sensing Peripheral Heuristic Evidence, Reinforcement, and Engagement System," issued August 17, 2021 (Compl. ¶56).
  • Technology Synopsis: This patent claims a method for identifying a condition in a home by training a neural network model, capturing sensor data, analyzing the data to identify abnormalities or new behavior patterns, determining a condition based on those patterns, and generating a notification to a caregiver (Compl. ¶246).
  • Asserted Claims: At least independent claim 1 (Compl. ¶245).
  • Accused Features: As with the ’318 Patent, the complaint accuses Alexa Together in combination with third-party fall detection services like Vayyar Care, alleging this combination trains a model, captures sensor data, analyzes it for abnormalities (falls), and generates notifications (Compl. ¶242, ¶249-253).

III. The Accused Instrumentality

  • Product Identification: The accused instrumentalities are primarily Amazon's "Alexa Care Hub" and "Alexa Together" services (collectively, "the ECSP Accused Products") (Compl. ¶58). For certain patents, the accused instrumentality also includes these services in combination with third-party functionality, such as Vayyar Care fall detection devices (Compl. ¶209).
  • Functionality and Market Context: Alexa Together is described as a subscription service designed to help users care for aging loved ones living independently (Compl. ¶71). The service works with Alexa-enabled devices (e.g., Amazon Echo) in the senior's home and an Alexa app on the caregiver's mobile device (Compl. ¶72). Key accused functionalities include setting up daily alerts for a loved one's "first Alexa activity of the day or if no activity is detected by a certain time" (Compl. ¶74), providing an "Activity Feed" that summarizes interactions with Alexa and smart home devices (Compl. ¶89), and creating a "Circle of Support" to add additional family members or friends to the caregiving team (Compl. ¶71). The complaint provides a screenshot from an Amazon marketing video showing a notification on a caregiver's phone stating, "First Alexa activity on Dad's Bedroom Echo" (Compl. p. 33).

IV. Analysis of Infringement Allegations

11,107,581 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
An engagement and care support platform (“ECSP”) computer device comprising at least one processor in communication with a chatbot and at least one memory device... Alexa Together is an ECSP used with an Echo or Alexa-enabled device, which is a computer device containing a processor and memory. Amazon's Alexa is alleged to be a chatbot. ¶71 col. 32:51-58
...the ECSP computer device in communication with a first client device associated with a senior user and a second client device associated with a caregiver... The Alexa Together service requires the senior user to have an Echo device (first client device) and the caregiver to have the Alexa app on their mobile device (second client device). ¶72 col. 33:59-64
store user information for the senior user... and the caregiver... The service requires two separate Amazon accounts, one for the senior user and one for the caregiver, to store user-specific information and settings for the service. ¶73 col. 33:3-6
determine for the senior user a first expected time of interaction with the chatbot via the first client device; Users can set up daily alerts for a loved one's "first Alexa use, or if it isn't used by a certain time," which determines the expected time of interaction. ¶74 col. 33:11-15
continuously monitor for a senior user interaction indicating that the senior user has interacted with the chatbot; The system continuously monitors the senior's interaction with Alexa and provides notifications and an activity feed to the caregiver showing these interactions. ¶75 col. 33:16-19
in response to not detecting the senior user interaction with the chatbot by the first expected time of interaction, transmit a message to the second client device of the caregiver... If no activity is detected by a certain time (e.g., 10 AM), the system sends a notification to the caregiver's device indicating the lack of interaction. A screenshot shows an alert for "No Alexa activity on Dad's devices" (Compl. p. 36). ¶76 col. 33:20-27
  • Identified Points of Contention:
    • Scope Questions: A central question may be whether Amazon's general-purpose Alexa voice assistant platform, which pre-existed the patent's priority date, constitutes the claimed "chatbot" within an "engagement and care support platform" when used for the accused service.
    • Technical Questions: The analysis may focus on whether the user-configured alert ("if it isn't used by a certain time") performs the specific function of "determin[ing] for the senior user a first expected time of interaction" as required by the claim, or if there is a technical distinction between a system-determined expectation and a user-set notification trigger.

11,114,203 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
...continuously monitor for a first senior user interaction... detect the first senior user interaction with the chatbot; The Alexa Together system continuously monitors for and detects a user's "first activity" or "first Alexa use." ¶112, ¶113 col. 41:14-18
...continuously monitor for a second senior user interaction... wherein the second senior user interaction is subsequent to the first... The system continuously monitors subsequent Alexa and smart home interactions after the first use, which are displayed in an "Activity Feed." ¶114 col. 41:19-21
determine an elapsed amount of time between detecting the first senior user interaction... and a current time without having detected the second senior user interaction... The system allows caregivers to set up "customized alerts" to be notified if the loved one has not used Alexa within a specified period of time (e.g., between 5:00 PM and 9:30 PM). ¶115 col. 41:22-26
when the elapsed amount of time... exceeds a predetermined threshold, transmit a message to the second client device of the caregiver... If no activity is detected within the specified, customized time window (the predetermined threshold), the system transmits an alert to the caregiver's device. A screenshot shows an alert for "No Alexa activity in Mom's home from 5-9:30pm" (Compl. p. 58). ¶116 col. 41:27-33
  • Identified Points of Contention:
    • Scope Questions: The dispute may turn on the definition of "predetermined threshold." The question is whether a user-defined time window for an alert (e.g., "between 5-9:30 PM") satisfies this limitation, or if the patent requires a system-defined, fixed duration of inactivity (e.g., "four hours of no activity").
    • Technical Questions: It may be contested whether the accused system actively "determine[s] an elapsed amount of time" in real-time as a calculation, versus simply triggering a pre-set alert if a condition (no activity within a window) is met at the end of that window.

V. Key Claim Terms for Construction

  • The Term: "chatbot" (’581 Patent, Claim 1; ’203 Patent, Claim 1)

  • Context and Importance: This term is critical because the core of the infringement allegation is that Amazon's Alexa voice assistant is the claimed "chatbot." The definition will determine whether a general-purpose voice assistant platform can be considered part of the patented "engagement and care support platform." Practitioners may focus on this term because the functionality of the accused Alexa platform largely predates the patents-in-suit.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The specification describes the chatbot as facilitating communication and enabling users to interact with the system via voice commands, which is consistent with the functionality of a voice assistant like Alexa (’203 Patent, col. 8:12-51).
    • Evidence for a Narrower Interpretation: The detailed description repeatedly refers to the chatbot as being "embedded in the ECSP application" (’203 Patent, col. 8:13-14), which might suggest an integrated software module rather than a broad, pre-existing platform like Alexa.

  • The Term: "determine an elapsed amount of time" (’203 Patent, Claim 1)

  • Context and Importance: This term is central to the method of detecting inactivity. The dispute will likely focus on whether the accused product's function of alerting after a user-defined window of inactivity constitutes "determining an elapsed amount of time," or if it is merely a conditional trigger.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The patent does not appear to specify how the time must be determined, which may allow for a simple check at the end of a time window to be considered a "determination." The claim language focuses on the result (transmitting a message when time exceeds a threshold) rather than the specific method of calculation (’203 Patent, col. 41:22-33).
    • Evidence for a Narrower Interpretation: The term "determine" could be construed to require an active calculation or running counter, which may differ from how the accused product's user-set alerts are technically implemented. Embodiments might describe a more complex, system-initiated calculation rather than a user-defined alert window.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges both induced and contributory infringement for all asserted patents. Inducement allegations are based on Defendant's marketing materials, "Frequently asked questions" websites, "Alexa Together Setup Guide," instructional videos, and customer support services, which allegedly instruct and encourage customers to use the accused products in an infringing manner (Compl. ¶86-91, ¶122-127). Contributory infringement is alleged on the basis that the accused products and associated software are material parts of the invention, not staple articles of commerce, and are especially adapted for infringing use (Compl. ¶94-97, ¶130-133).
  • Willful Infringement: The complaint alleges willful infringement for all asserted patents. The basis for willfulness includes alleged pre-suit knowledge stemming from the business partnership between Plaintiff and Defendant to adapt the patented technology for Alexa devices, as well as multiple letters and emails Plaintiff allegedly sent to Defendant notifying it of the published patent applications, allowances, and issued patents, and their applicability to the accused products (Compl. ¶42-44, ¶82, ¶99, ¶118, ¶135).

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

  • A core issue will be one of definitional scope: can the term "chatbot," as used in the context of a specific "engagement and care support platform," be construed to cover a pre-existing, general-purpose voice assistant platform like Amazon Alexa, or does the patent’s language require a more integrated, purpose-built conversational agent?
  • A key evidentiary question will be one of functional implementation: does the accused Alexa Together service, which allows users to set customized alerts for periods of activity or inactivity, perform the specific, multi-step monitoring processes required by the claims—such as "determin[ing] a first expected time of interaction" or "determin[ing] an elapsed amount of time"—or is there a fundamental mismatch in the technical operation?
  • A third question will relate to joint infringement and liability: for the patents related to machine learning and sensor analysis, can Plaintiff establish that Defendant's integration of third-party fall detection devices like Vayyar Care creates a "joint enterprise" that practices all steps of the claimed methods, particularly the step of "training a machine learning module"?
