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

U.S. Patent No. 11,403,932 - “Digitized Voice Alerts”

Issued August 2, 2022.

The Invention Explained

  • Problem Addressed: The patent describes a need for an improved method of notifying a highly mobile public about emergencies or other critical events, particularly in situations where reading a text-based alert is impractical or dangerous, such as while driving (Compl. ¶9; ’932 Patent, col. 1:52-col. 2:1). Existing systems like the Personal Localized Alerting Network (PLAN) were noted as being text-only (Compl. ¶9; ’932 Patent, col. 15:5-8).
  • The Patented Solution: The invention is a system that can determine an emergency situation, generate a corresponding text message, convert that message into a digitized voice alert, and transmit the voice alert for automatic playback on remote devices (e.g., smartphones, in-vehicle systems) (’932 Patent, Abstract). The system is described as being capable of broadcasting these alerts through cellular networks and supporting translations into multiple languages to enhance accessibility (’932 Patent, col. 3:1-4; Fig. 4).
  • Technical Importance: The described technology sought to make emergency alerts more effective by providing an audible message that does not require visual attention from the recipient, thereby improving safety and comprehension during critical events (’932 Patent, col. 15:1-8).

Key Claims at a Glance

  • The complaint asserts infringement of one or more of claims 1-18 (Compl. ¶8).
  • Independent Claim 1 (Method): The essential elements include:
    • Determining an emergency situation affecting a specified region.
    • Generating and converting a text message indicative of the situation into a digitized voice alert.
    • Converting the voice alert into at least one selected language for broadcast.
    • Transmitting the voice alert through specific towers of a cellular network for distribution to wireless handheld devices in that region.
  • Independent Claim 18 (Method): The essential elements include:
    • Determining an emergency situation affecting a specified region.
    • Generating and converting a text message indicative of the situation into a digitized voice alert.
    • Transmitting the voice alert through specific towers of a cellular network for distribution.
  • The complaint reserves the right to assert dependent claims by alleging infringement of claims 1-18 generally (Compl. ¶8).

III. The Accused Instrumentality

Product Identification

The complaint does not name any specific accused products or services, referring to them generally as "devices/products and systems" and "products and services and related services" operated by Defendant ReGroup (Compl. ¶¶ 8, 11).

Functionality and Market Context

The accused instrumentalities are alleged to provide "instant/real-time Voice alerts automatically to remote electronic devices" (Compl. ¶7). Their functionality is described as including the "automatic digitized conversion of text messages to voice alerts for transmission to remote electronic devices" (Compl. ¶9). The complaint does not provide sufficient detail for a more specific analysis of the accused functionality or its market context.

IV. Analysis of Infringement Allegations

The complaint alleges that Defendant’s systems infringe the ’932 patent by providing automatic voice alerts (Compl. ¶¶ 7, 9). It references an "attached Exhibit B" as providing support for the infringement allegations; however, this exhibit was not included with the provided complaint document (Compl. ¶10). In the absence of this exhibit or a detailed claim chart, a specific element-by-element analysis is not possible based on the complaint's text alone. The infringement theory appears to be that Defendant’s systems for converting text-based alerts to voice for remote delivery perform the steps recited in the asserted claims of the ’932 Patent. No probative visual evidence provided in complaint.

  • Identified Points of Contention:
    • Scope Questions: Claim 1 requires "transmitting the digitized voice alert through specific towers of a cellular communications network." A potential issue is whether this language covers modern alert systems that may use internet protocol (IP) based delivery over cellular data or Wi-Fi, as opposed to a specific cell-broadcast technology implied by the "specific towers" language.
    • Technical Questions: A key factual question will be how the accused system performs the claimed step of "determining an emergency situation." The complaint does not allege specific facts on this point, and its meaning—whether limited to public safety emergencies or inclusive of private alerts (e.g., home security)—may be a point of dispute.

V. Key Claim Terms for Construction

  • The Term: "determining an emergency situation affecting a specified region"

  • Context and Importance: This term appears at the beginning of independent claims 1 and 18 and acts as the trigger for the claimed method. Its construction will be critical for defining the scope of infringement, as it dictates what type of event initiates the infringing process. Practitioners may focus on whether this is limited to public, government-declared emergencies or extends to private or commercial alerts.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: The specification suggests "an 'activity' as utilized herein may be, for example, any number of different actions or events," including a security sensor detecting an opened door in a home or a live speech from a public official (’932 Patent, col. 2:40-48). This could support a construction that includes a wide range of events beyond public emergencies.
    • Evidence for a Narrower Interpretation: The claim language "affecting a specified region" and the patent’s discussion of the PLAN system could support a narrower construction focused on geographically-targeted public safety alerts, rather than person-specific or device-specific notifications like a home security alert (’932 Patent, col. 15:1-15; col. 30:37-40).

  • The Term: "transmitting the digitized voice alert through specific towers of a cellular communications network"

  • Context and Importance: This limitation in claims 1 and 18 defines the transmission mechanism. Its interpretation is central to whether the claims read on modern notification systems that predominantly use IP-based data transmission.

  • Intrinsic Evidence for Interpretation:

    • Evidence for a Broader Interpretation: A party might argue that any transmission that utilizes a cellular network's infrastructure, including IP data packets sent to a smartphone, meets this limitation, as the data must pass through the carrier's towers.
    • Evidence for a Narrower Interpretation: The patent’s discussion of the PLAN system, which uses cell broadcast technology to send messages from cell towers to all devices in a geographic area, may support a narrower construction limited to such broadcast-style transmissions, as distinct from individually addressed IP data packets (’932 Patent, col. 20:5-14).

VI. Other Allegations

  • Indirect Infringement: The complaint alleges induced infringement, stating that ReGroup "actively encouraged or instructed" customers on how to use the accused products in an infringing manner (Compl. ¶11). It also alleges contributory infringement, asserting that the "components marketed and sold by ReGroup do not have any substantial non-infringing uses" (Compl. ¶12).
  • Willful Infringement: The complaint does not contain an explicit allegation of willful infringement.

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

  • A core issue will be one of claim scope versus evolving technology: can the claim limitation "transmitting...through specific towers of a cellular communications network," which suggests a broadcast-style architecture, be construed to cover modern systems that deliver alerts as IP-based data over cellular or Wi-Fi networks?
  • A key evidentiary question will be one of factual sufficiency: given the high-level nature of the complaint, the case may turn on whether the Plaintiff can produce discovery evidence to demonstrate that the accused systems perform each specific step of the claimed methods, particularly the antecedent step of "determining an emergency situation" as defined by the patent.
