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

U.S. Patent No. 7,930,340 - *"Network Transaction Portal to Control Multi-Service Provider Transactions"*

  • Patent Identification: U.S. Patent No. 7,930,340, "Network Transaction Portal to Control Multi-Service Provider Transactions," issued April 19, 2011.

The Invention Explained

  • Problem Addressed: The patent describes a problem in early internet commerce where transactions involving multiple parties (e.g., a customer, a car dealer, and a bank) were disjointed. A user connecting from one service provider's website to another via a hyperlink would effectively disconnect from the first, resulting in a "lack of cooperation, control, and interaction" and preventing a single, managed, real-time transaction ('340' Patent, col. 2:18-24). Existing systems were limited to "browse-only interactions or simple 'deferred' purchases involving a single service provider" ('340 Patent, col. 1:42-44).
  • The Patented Solution: The invention proposes a centralized system, or "hub," that acts as a "network transaction portal" to manage a multi-party transaction ('340 Patent, col. 1:1-3). A "network transactional application" at the hub "holds the transaction captive" and uses a router to controllably connect a user to various remote service providers, or "nodes" ('340 Patent, Abstract). This architecture, depicted in figures such as Figure 6, is designed to allow one entity to maintain control over the entire transaction flow, enabling verification and management of each step with different providers, as illustrated in the multi-party purchase example of Figure 12 ('340 Patent, Fig. 6, Fig. 12).
  • Technical Importance: This approach aimed to provide a framework for more sophisticated, integrated e-commerce experiences beyond simple webpage-to-webpage navigation, enabling coordinated services from multiple vendors within a single transactional context.

Key Claims at a Glance

  • The complaint does not identify specific claims, but independent claim 1 is representative of the system described.
  • The essential elements of independent claim 1 include:
    • A first server with a "context manager" that supports a first web page allowing a user to access multiple possible "Web transactions from a plurality of Web merchants."
    • A "user transaction manager" allowing the user to enter a transaction via a second web page.
    • An "account settling manager" that allows the user to communicate with a "payment program running on a second server remote from the first server" to settle an account.
    • A "switching component" that temporarily switches the user from the first server to the second remote server for account settlement.
    • An "object router" through which the user directly communicates with the payment program, with the object router enabling the user's real-time transaction with a web merchant "while providing interaction and management between the first and second servers." ('340 Patent, col. 39:41 - col. 40:1).
  • The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

  • The complaint accuses "at least its TurboTax, QuickBooks, Quicken and other mobile and other Web apps" (Compl. ¶8).

Functionality and Market Context

  • The complaint describes the accused products as providing "IRS filing and payment services, accounting and financial services" (Compl. ¶8).
  • The complaint does not provide specific details on the technical operation or architecture of the accused products, nor does it contain allegations regarding their market positioning.

IV. Analysis of Infringement Allegations

The complaint makes broad allegations of infringement without providing an element-by-element mapping of any asserted claim to the accused instrumentalities. Therefore, a claim chart summary cannot be constructed from the provided document. The infringement theory is articulated as Defendant making and using "products and practices... and systems and methods that fall within the scope of the claims of the '340 patent" (Compl. ¶8).

No probative visual evidence provided in complaint.

  • Identified Points of Contention:
    • Architectural Questions: A primary question will be whether the architecture of the accused Intuit products can be mapped onto the specific multi-server system recited in claim 1. This raises the question of what evidence will show that Intuit’s services utilize a "first server" with a "context manager" that interacts with a separate "second server" running a "payment program" in the manner claimed.
    • Technical Questions: The infringement analysis may focus on whether Intuit's software contains the specific functional components of a "switching component" and an "object router." A key point of contention could be whether standard API calls and data exchanges between an Intuit application and third-party services (like the IRS or a bank) perform the specific function of an "object router" that provides "interaction and management between the first and second servers" as required by the claim language.

V. Key Claim Terms for Construction

The complaint does not identify any claim terms for construction. However, based on the technology and the elements of claim 1, practitioners may focus on the following terms:

  • The Term: "switching component"

    • Context and Importance: This term is central to the claimed architecture for managing the user's connection between different servers. The scope of this term will be critical to determining whether a standard web architecture that redirects or links a user to a separate payment service infringes, or if a more specialized, integrated component is required.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The specification describes this component in functional terms as "multi-protocol value-added network switching software to switch between remote service provider nodes" ('340 Patent, col. 9:37-40), which may support an interpretation covering various software-based routing mechanisms.
      • Evidence for a Narrower Interpretation: The patent also discloses a specific "value-added network (VAN) switch" architecture with distinct boundary, switching, management, and application service layers, as shown in Figure 14. This detailed embodiment could be used to argue for a narrower construction limited to such a structured switch ('340 Patent, Fig. 14; col. 15:27-40).

  • The Term: "object router"

    • Context and Importance: The claim requires that the user communicates with the payment program "via an object router." The definition of this term is crucial, as it may distinguish the claimed invention from conventional client-server communication protocols.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The specification defines a router broadly as "software to create or allow a link to potentially remote and geographically distributed software" ('340 Patent, col. 6:47-49).
      • Evidence for a Narrower Interpretation: The patent provides a highly detailed description of an "object router" implemented with specific software layers, a meta-compiler, and a library of classes (e.g., "WxRemoteObject", stubs, and skeletons) that manage remote object communication ('340 Patent, col. 17:10-50; Fig. 16). This extensive disclosure may support an argument that the term is limited to a system employing such object-oriented remote procedure call mechanisms, rather than more generic data-routing methods.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges that Defendant "has and is actively inducing and/or contributing to the infringement" but provides no specific supporting facts, such as references to user manuals or instructions (Compl. ¶10).
  • Willful Infringement: The complaint alleges willfulness based on pre-suit knowledge, stating that Defendant's "Senior Executive Al Ko was put on notice in 2018" (Compl. ¶9).

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

  • A core issue will be one of architectural mapping: Can the plaintiff demonstrate that Intuit's software products, which facilitate financial tasks like tax filing, embody the specific two-server architecture controlled by a "switching component" and an "object router" as recited in the patent's claims, or is there a fundamental mismatch between the accused products and the claimed system?
  • A key evidentiary question will be one of technical implementation: What evidence will be presented to prove that the communication protocols used in Intuit's products function as the claimed "object router" that provides "interaction and management between the first and second servers," as opposed to constituting conventional client-server or API-based communications that fall outside the scope of the claims?
