• Case Identification: 2:24-cv-00409, E.D. Tex., 06/04/2024
• Venue Allegations: Plaintiff alleges venue is proper in the Eastern District of Texas because Defendant maintains an established place of business in the district.
• Core Dispute: Plaintiff alleges that certain unidentified products and services offered by Defendant infringe a patent related to methods and systems for delivering and updating audio announcements.
• Technical Context: The technology concerns a structured system for delivering dynamic audio content (e.g., news, alerts, reports) to an end-user device, allowing for content to be updated, added, or replaced based on unique identifiers.
• Key Procedural History: The asserted patent is subject to a terminal disclaimer. It is also a continuation of a chain of applications tracing back to an application filed in 2006, which may be relevant for interpreting claim scope based on the state of the art at that time.

Case Timeline

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

U.S. Patent No. 8,498,388 - "Method and system for announcement"

• Issued: July 30, 2013

The Invention Explained

• Problem Addressed: The patent describes prior art methods for delivering audio announcements—such as dialing into an Interactive Voice Response (IVR) system, listening to radio broadcasts, or navigating websites—as lacking "effectiveness and timeliness" because they are often static, require repetitive user action to get updates, or are delivered infrequently. (’388 Patent, col. 1:21-2:2).
• The Patented Solution: The invention proposes a system where a client device (an "announcer") receives a structured "announcement package" from a server. This package contains one or more "announcement items," each with a unique "item identity" and associated "audio data." (’388 Patent, Abstract). When the announcer receives a new package or item, it can use the item identity to determine whether the new item is an update to existing content or entirely new content, allowing it to modify, replace, or add announcements efficiently. (’388 Patent, col. 7:25-51). This structure is designed to facilitate the timely delivery of dynamic audio information.
• Technical Importance: The described approach provides a framework for managing and distributing dynamic audio content to endpoints, moving beyond static recordings or monolithic broadcasts toward a more flexible, updatable system. (’388 Patent, col. 2:1-2, 17-21).

Key Claims at a Glance

• The complaint does not identify specific asserted claims, instead referencing "Exemplary '388 Patent Claims" in an external exhibit not attached to the public filing. (Compl. ¶ 11). Independent claim 1 is representative of the patent's method claims.
• Independent Claim 1 (Method):
  • receiving a first announcement item by the telephone, the first announcement item comprising a first item identity and a first audio data;
  • receiving a second announcement item by the telephone, the second announcement item comprising a second item identity and a second audio data;
  • determining by the telephone if the second item identity matches the first item identity; and
  • in response to determining that the second item identity matches the first item identity, updating the first audio data with the second audio data by the telephone.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

The complaint does not name any specific accused products or services in its text. It refers to them as the "Exemplary Defendant Products" that are purportedly identified in "charts incorporated into this Count." (Compl. ¶ 11). These charts, part of Exhibit 2, were not filed with the complaint.

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the functionality of the accused instrumentalities. It alleges only that the "Exemplary Defendant Products practice the technology claimed by the '388 Patent" and that they have been "made, used, sold, imported, and offered for sale by Defendant and/or its customers." (Compl. ¶¶ 11, 16).

IV. Analysis of Infringement Allegations

The complaint incorporates infringement allegations by reference to an external document, Exhibit 2, which was not provided with the filing. (Compl. ¶¶ 16-17). The complaint’s narrative theory is that Defendant’s "Exemplary Defendant Products" directly infringe by practicing the claimed technology and satisfying all claim elements. (Compl. ¶ 16). The complaint also alleges direct infringement through Defendant’s internal testing and use of these products. (Compl. ¶ 12). Due to the lack of specific allegations or claim charts in the complaint itself, a detailed element-by-element analysis is not possible.

• Identified Points of Contention:
  • Scope Questions: The asserted independent claims are directed to a "telephone." (’388 Patent, claims 1, 12). A central dispute may arise over whether Defendant's accused products, which may be smart speakers (e.g., Amazon Echo) or software applications operating over IP networks, fall within the legal construction of the term "telephone" as understood in the context of a patent with a 2006 priority date.
  • Technical Questions: Claim 1 requires the "telephone" itself to perform the steps of "determining" if item identities match and "updating" the audio data locally. (’388 Patent, col. 13:50-62). A key factual question will be whether the accused products perform this comparison and data update logic on the client device, or if this functionality is handled by Defendant's cloud-based servers before information is sent to the device. The complaint provides no evidence to resolve this question.

V. Key Claim Terms for Construction

• The Term: "telephone"
• Context and Importance: This term appears in independent claims 1 and 12 and defines the device performing the patented method and embodying the patented system. The viability of Plaintiff's infringement case may depend on whether this term is construed broadly enough to cover modern, IP-based voice-enabled devices or is limited to more traditional telecommunications equipment.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification discloses that an "announcer can be included in a personal computer, a personal data assistance (PDA), a smartphone or a television," suggesting the invention is not limited to a conventional telephone. (’388 Patent, col. 12:35-38). The patent also describes communication occurring over various networks, including the Internet, corporate VPNs, and wireless networks like WiFi, not just traditional telephony networks. (’388 Patent, col. 3:1-11).
  • Evidence for a Narrower Interpretation: The background section frames the problem partly in the context of a user dialing a "telephone number" to connect to an IVR machine over a "telephony network." (’388 Patent, col. 1:22-30). This context could be used to argue that the term "telephone" should be understood in its traditional sense as a device primarily connected to such a network.

VI. Other Allegations

• Indirect Infringement: Plaintiff alleges induced infringement based on conduct occurring "at least since being served by this Complaint." (Compl. ¶ 15). The alleged inducing acts include distributing "product literature and website materials" that instruct end users on how to use the accused products in a manner that allegedly infringes the ’388 Patent. (Compl. ¶ 14).
• Willful Infringement: The complaint does not use the word "willful" but lays a foundation for such a claim based on post-suit conduct. It alleges that the service of the complaint provides Defendant with "actual knowledge" of infringement and that Defendant's continued infringement thereafter is done despite this knowledge. (Compl. ¶¶ 13-14).

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

• A core issue will be one of definitional scope: can the term "telephone," which appears in the asserted independent claims and is rooted in a 2006-priority patent, be construed to cover modern smart speakers and software clients that operate primarily over the Internet?
• A key evidentiary question will be one of locus of operation: does the accused system perform the critical claim steps of "determining" a match between item identities and "updating" audio data on the local client device as required by the claims, or are these logical operations performed in the cloud? The complaint provides no factual allegations to address this distinction.

No probative visual evidence provided in complaint.
