Case Timeline

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

• Patent Identification: U.S. Patent No. 11,403,932, Digitized Voice Alerts, issued August 2, 2022.

The Invention Explained

• Problem Addressed: The patent's background section identifies a need for an "improved and efficient approach for transmitting or broadcasting instant voice alerts to remote electronic devices automatically during times of emergencies or as a part of security monitoring systems" ('932 Patent, col. 1:63-67). This is framed in the context of a "highly mobile society" where audible alerts are needed for people who cannot view text messages, such as drivers (Compl. ¶9; '932 Patent, col. 15:1-8).
• The Patented Solution: The invention is a system that can detect an event, generate a corresponding text message, convert that text into a digitized voice alert, and transmit the voice alert over a network to remote devices like smartphones or in-vehicle systems ('932 Patent, Abstract; FIG. 4). The system is described as being capable of handling both sensor-triggered events and live announcements, as well as converting the voice alert into multiple languages for broadcast ('932 Patent, Abstract; col. 3:1-4).
• Technical Importance: The technology sought to provide timely, audible notifications to users who might be distracted or otherwise unable to read text-based alerts, thereby improving the effectiveness of emergency and security notifications (Compl. ¶9).

Key Claims at a Glance

• The complaint asserts infringement of one or more of claims 1-18, which includes independent method claims 1 and 18, independent system claim 10, and independent non-transitory medium claim 17 (Compl. ¶8).
• Independent Claim 1 (Method) includes the following essential elements:
  • determining an emergency situation affecting a specified region
  • generating and converting a text message indicative of the emergency situation into a digitized voice alert
  • converting the digitized voice alert into at least one language selected from a plurality of languages
  • transmitting the digitized voice alert through specific towers of a cellular communications network in the specified region for distribution
• Independent Claim 18 (Method) includes the following essential elements:
  • determining an emergency situation affecting a specified region
  • generating and converting a text message indicative of the emergency situation into a digitized voice alert
  • transmitting the digitized voice alert through specific towers of a cellular communications network in the specified region for distribution
• The complaint reserves the right to assert other claims, including dependent claims, by alleging infringement of "one or more of claims 1-18" (Compl. ¶8).

III. The Accused Instrumentality

Product Identification

The complaint does not name any specific accused Siemens products, methods, or services. It refers broadly to "devices/products and systems" that Defendant "maintains, operates, and administers" (Compl. ¶8).

Functionality and Market Context

The complaint alleges that Defendant's systems provide for "instant/real-time Voice alerts automatically to remote electronic devices" by performing "automatic digitized conversion of text messages to voice alerts for transmission" (Compl. ¶¶ 7, 9). These actions are alleged to provide "monetary and commercial benefit" to the Defendant (Compl. ¶8). The complaint states that support for these allegations is contained in exhibits that were not provided with the filed complaint (Compl. ¶10).

IV. Analysis of Infringement Allegations

The complaint does not contain a claim chart or provide sufficient detail to construct one. It states that "Support for the allegations of infringement may be found in the attached Exhibit B," which allegedly contains screenshots from a Siemens publication provided as Exhibit C (Compl. ¶10). As these exhibits were not included in the provided court filing, the specific factual basis for infringement is not detailed. The complaint's narrative theory is that Siemens provides systems which perform the functions of the asserted claims, including converting text to voice for alerts (Compl. ¶9).

No probative visual evidence provided in complaint.

Identified Points of Contention

• Specificity: A primary procedural question may be whether the complaint's generalized allegations against unspecified "devices/products and systems" are sufficient to state a claim for patent infringement without identifying at least one accused instrumentality by name (Compl. ¶8).
• Technical Questions: The infringement analysis will raise several technical questions.
  • What evidence will Plaintiff offer to show that the accused systems "determin[e] an emergency situation" as recited in the claims, versus processing other types of information? ('932 Patent, col. 30:37-38).
  • Does the architecture of the accused systems map onto the claimed two-step process of first "generating... a text message" and then "converting" that text message into a voice alert? ('932 Patent, col. 30:40-42).
  • For infringement of claims requiring multi-language support (e.g., Claim 1), what evidence will show that the accused systems perform the step of "converting the digitized voice alert into at least one language selected from a plurality of languages"? ('932 Patent, col. 30:43-46).
  • A key question will be how Plaintiff intends to prove that the accused systems transmit alerts "through specific towers of a cellular communications network in the specified region," a limitation that may suggest a specific geo-targeting functionality ('932 Patent, col. 30:47-50).

V. Key Claim Terms for Construction

The Term: "determining an emergency situation" ('932 Patent, col. 30:37)

• Context and Importance: This term defines the trigger for the claimed method. Its construction will be critical to the scope of infringement, determining whether the claims are limited to public safety emergencies or can also cover private events like security sensor alerts.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification describes that an "activity" as utilized herein may be, for example, any number of different actions or events," including a security sensor detecting an opened door or a live speech by a public official, which may support a broad definition ('932 Patent, col. 2:40-49).
  • Evidence for a Narrower Interpretation: The claim language itself links the "emergency situation" to a "specified region" and transmission via "specific towers of a cellular communications network," which could be argued to narrow the scope to geographically-targeted public alerts, such as those associated with the Personal Localized Alerting Network ("PLAN") discussed in the complaint and patent (Compl. ¶9; '932 Patent, col. 15:1-12).

The Term: "specific towers of a cellular communications network in the specified region" ('932 Patent, col. 30:47-50)

• Context and Importance: This limitation appears to require a particular method of transmission. Proving infringement will depend on whether the accused Siemens systems utilize such a mechanism. Practitioners may focus on this term because it could be a significant point of non-infringement if the accused systems use standard internet-based or non-geo-targeted transmissions.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: A party might argue this term simply means the cellular towers that happen to be located within the specified geographic region, without implying any special targeting capability.
  • Evidence for a Narrower Interpretation: The patent’s discussion of providing emergency alerts to users in a "specified region" and its references to the PLAN system may support a construction requiring an intentional, geo-fenced broadcast directed to a specific set of cellular towers, rather than a general transmission over a network that happens to reach a region ('932 Patent, col. 15:25-45).

VI. Other Allegations

Indirect Infringement

The complaint alleges inducement, stating that Defendant "has actively encouraged or instructed others (e.g., its customers...)" on how to use its products in an infringing manner (Compl. ¶11). It also pleads contributory infringement, alleging that the "components marketed and sold by Defendant do not have any substantial non-infringing uses" (Compl. ¶12).

Willful Infringement

The complaint does not use the word "willful" in its allegations. However, the prayer for relief requests an accounting for acts of infringement and an award of "additional damage for any such acts," which may be a reference to enhanced damages under 35 U.S.C. § 284 (Compl., p. 5, ¶c). The complaint alleges no facts regarding Defendant's pre-suit knowledge of the patent.

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

• Evidentiary Specificity: A threshold issue will be whether the plaintiff can connect its general allegations to specific, named Siemens products and provide evidence that they operate as claimed. The lack of detail in the complaint may be an early focus of the litigation.
• Definitional Scope and Technical Operation: The case will likely turn on questions of claim scope. A central issue will be whether the accused systems meet the "transmitting... through specific towers" limitation, which raises a key question for the court: does this claim language require a specialized, geo-targeted cellular broadcast function, or does standard network transmission suffice?
• Functional Equivalence: For claims requiring multi-language capabilities, such as Claim 1, a key evidentiary question will be one of functional equivalence: does an accused system that may provide alerts in a single language, or allow a user to select a system language, meet the claimed step of actively "converting the digitized voice alert into at least one language selected from a plurality of languages"?
