Case Timeline

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

U.S. Patent No. 12,300,366 - "Multi-services application gateway and system employing the same"

(’366 Patent, issued May 13, 2025)

The Invention Explained

• Problem Addressed: The patent’s background section describes the growing complexity of the "digital home," which contains a myriad of interconnected digital devices for communication, entertainment, and security, and notes that managing this environment can be a "daunting and intimidating task" for technologically challenged users (ʼ366 Patent, col. 1:30-41).
• The Patented Solution: The invention is an "intelligent gateway device" that acts as a central hub for managing application services and communications for all digital devices on a local network (ʼ366 Patent, Abstract). As depicted in Figure 1A, the gateway (10) connects various local endpoint devices (e.g., PCs 30a-c, VoIP phones 40) to each other and to external networks, providing a "services framework" to manage service configuration, authentication, and execution of service logic modules for those devices (ʼ366 Patent, Abstract; col. 8:35-52).
• Technical Importance: The technology aims to simplify the management of a complex digital home environment by moving beyond simple network routing to provide a centralized platform for service delivery, management, and support for a wide range of devices and applications (ʼ366 Patent, col. 6:3-11).

Key Claims at a Glance

• The complaint alleges infringement of "one or more claims" and refers to "Exemplary '366 Patent Claims" identified in an exhibit incorporated by reference (Compl. ¶11).
• However, the complaint as filed does not specify which independent or dependent claims are asserted and does not include the referenced exhibit containing the claim charts.

III. The Accused Instrumentality

Product Identification

The complaint identifies the accused instrumentalities as the "Exemplary Defendant Products" (Compl. ¶11).

Functionality and Market Context

The complaint does not provide any specific details regarding the names, features, or technical functionality of the accused products. It alleges that these products are identified in claim charts in an exhibit that was not provided with the complaint (Compl. ¶11, ¶16).

IV. Analysis of Infringement Allegations

The complaint alleges that the "Exemplary Defendant Products practice the technology claimed by the '366 Patent" and "satisfy all elements of the Exemplary '366 Patent Claims" (Compl. ¶16). It incorporates by reference claim charts from an external Exhibit 2, which was not included with the complaint, to support its allegations of infringement (Compl. ¶17). The complaint also alleges that Defendant's internal testing and use of the products constitutes direct infringement (Compl. ¶12).

Due to the absence of the referenced claim charts and the lack of specific factual allegations in the body of the complaint mapping accused product features to claim elements, a detailed analysis of the infringement allegations is not possible.

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

The complaint does not identify any specific asserted claims from the ’366 Patent. Therefore, an analysis of key claim terms for construction is not possible based on the provided documents.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant sells its products to customers and distributes "product literature and website materials inducing end users" to use the products in an infringing manner (Compl. ¶14-15). The factual basis for this allegation is said to be detailed in the unprovided Exhibit 2 (Compl. ¶14).
• Willful Infringement: The complaint alleges that service of the complaint and its attached (but unprovided) claim charts constitutes "Actual Knowledge of Infringement" (Compl. ¶13). It further alleges that Defendant's continued infringing activities despite this knowledge support a claim for post-suit infringement damages and potentially an exceptional case finding (Compl. ¶14; Prayer for Relief ¶D, ¶E.i).

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

• Evidentiary Sufficiency: A primary threshold question will be whether the complaint, which makes conclusory allegations and relies entirely on an unprovided external exhibit for its substantive infringement theory, contains sufficient factual matter to state a plausible claim for relief under prevailing federal pleading standards.
• Claim Scope: Assuming the case proceeds, a central issue will be the scope of the asserted claims. The dispute will likely focus on whether the architectural elements of Defendant’s products, once identified, fall within the patent's definition of an "intelligent gateway" with an integrated "services framework," or if they represent a technologically distinct approach to smart home device management.
