Case Timeline

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

U.S. Patent No. 8,938,799 - "Security Protection Apparatus and Method for Endpoint Computing Systems"

• Issued: January 20, 2015

The Invention Explained

• Problem Addressed: The patent’s background section describes the conventional approach to enterprise security, where multiple defense and immunization software modules from various vendors are installed directly on each host computer (’799 Patent, col. 4:42-45). This creates a "heterogeneous environment" that may lead to software conflicts, performance degradation, management complexity, and high total-cost-of-ownership (Compl. ¶15; ’799 Patent, col. 4:49-67).
• The Patented Solution: The invention proposes a "Unified Security Management System" that includes a hardware and software "security subsystem," referred to as a Security Utility Blade (SUB), which resides in a managed endpoint device (’799 Patent, col. 5:20-25). This SUB is architecturally separate from the host's primary operating system and is positioned between the host and the network (’799 Patent, Fig. 2A). It functions as a centrally managed "open platform" capable of receiving, storing, and executing security software modules from any participating vendor, thereby isolating security functions from the host and simplifying deployment (Compl. ¶14; ’799 Patent, Abstract; col. 8:41-55).
• Technical Importance: The described approach sought to standardize and centralize the deployment and management of endpoint security, creating a more homogeneous and controlled environment intended to lower IT operational costs and improve security posture (’799 Patent, col. 6:1-6).

Key Claims at a Glance

• The complaint asserts independent Claim 14 (Compl. ¶31).
• Claim 14 requires:
  • A security subsystem configurable between a network and a host of an endpoint,
  • comprising computing resources for providing:
  • an open platform for receiving and executing security function software modules from multiple vendors,
  • for providing defense functions for protection of the host.
• The complaint does not assert any dependent claims but alleges infringement of "one or more claims, including at least Claim 14" (Compl. ¶31).

III. The Accused Instrumentality

Product Identification

The Oracle Communications Diameter Signal Router (“Oracle Communications DSR”) (Compl. ¶27).

Functionality and Market Context

The complaint alleges the Oracle Communications DSR "provides deployment of security policies" with "multilayered" protection from the network layer to the application layer (host of endpoints) (Compl. ¶27). It is described as a protocol used by network elements in LTE and 3G networks to enable and monetize services such as tiered data plans, application-specific Quality of Service (QoS), and Internet of Things (IoT) solutions (Compl. ¶27). The complaint's description positions the accused product as a network infrastructure element rather than a component of an individual user endpoint.

IV. Analysis of Infringement Allegations

The complaint states that a claim chart is attached as Exhibit B but does not provide the exhibit (Compl. ¶¶ 31, 36). The infringement theory is therefore based on the narrative allegations in the complaint.

The complaint alleges that the Oracle Communications DSR infringes at least Claim 14 by providing "deployment of security policies" and "multilayered" protection (Compl. ¶¶ 27, 31). The complaint asserts that these functionalities satisfy all elements of at least Claim 14 of the ’799 Patent (Compl. ¶36). No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Questions: The patent specification frequently describes the "security subsystem" as a "Security Utility Blade (SUB)" that is physically integrated with or attached to an "endpoint computing system" such as a desktop PC, laptop, or server (’799 Patent, Abstract; col. 5:20-25; Figs. 2B-2D). The accused instrumentality is a "Diameter Signal Router," described as a network element for 3G/LTE networks (Compl. ¶27). This raises the question of whether a network-level router can be considered a "security subsystem... of an endpoint" within the meaning of the claims, or if the claims are limited to components physically associated with the host device itself.
• Technical Questions: Claim 14 requires "an open platform for receiving and executing security function software modules from multiple vendors" (’799 Patent, col. 26:50-53). The complaint alleges the DSR "provides deployment of security policies" (Compl. ¶27). A central technical question will be what evidence demonstrates that the accused DSR functions as an "open platform" that can "receive and execute" discrete software modules from "multiple vendors," as opposed to operating as a closed system that implements proprietary or pre-configured security rules.

V. Key Claim Terms for Construction

The Term: "security subsystem"

• Context and Importance: This term defines the fundamental apparatus of the invention. Its construction will be critical in determining whether the accused network router falls within the scope of a claim that the patent specification appears to direct toward components of an "endpoint" device.
• Intrinsic Evidence for a Broader Interpretation: A party could argue that the plain language "configurable between a network and a host of an endpoint" does not strictly require physical integration and could encompass a separate network device that logically sits between the network and the host (’799 Patent, col. 26:46-47).
• Intrinsic Evidence for a Narrower Interpretation: The specification consistently refers to the invention as a "Security Utility Blade (SUB)" and depicts it in figures as a card installed in a motherboard slot or as a chip embedded on the motherboard of a PC or laptop, suggesting a component physically integral to the endpoint (’799 Patent, col. 5:21-25; Figs. 2A-2D).

The Term: "open platform for receiving and executing security function software modules from multiple vendors"

• Context and Importance: This limitation defines a key functional capability of the claimed invention. The infringement analysis will depend on whether the accused DSR’s architecture for "deployment of security policies" meets this definition.
• Intrinsic Evidence for a Broader Interpretation: A party may contend that any system allowing for the implementation of security rules or policies originating from different sources constitutes an "open platform."
• Intrinsic Evidence for a Narrower Interpretation: The specification describes a specific architecture where the SUB functions as a "repository" for software modules downloaded from various vendors, which are then stored and executed within the SUB (’799 Patent, col. 8:41-55). This may support a narrower construction requiring the ability to dynamically download, store, and run third-party executable code, not merely apply configurable policies.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials inducing end users and others to use its products in the customary and intended manner that infringes" (Compl. ¶34). It also pleads contributory infringement (Compl. ¶31).

Willful Infringement

The willfulness claim is based on post-suit knowledge. The complaint alleges that "Defendant has knowledge of its infringement... at least as of the service of the present complaint" and that it continued to infringe despite this knowledge (Compl. ¶¶ 29, 34). No facts supporting pre-suit knowledge are alleged.

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

• A core issue will be one of definitional scope: can the claimed "security subsystem," which the patent specification describes in the context of a component physically integrated with an "endpoint" device like a PC, be construed to cover the accused "Oracle Communications Diameter Signal Router," a network-layer infrastructure product?
• A key evidentiary question will be one of technical operation: does the accused DSR’s method for the "deployment of security policies" meet the claim requirement of an "open platform for receiving and executing security function software modules from multiple vendors," or is there a fundamental mismatch between the product's architecture and the specific functionality described in the patent?
