Case Timeline

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

U.S. Patent No. 8,099,368 - "Intermediary service and method for processing financial transaction data with mobile device confirmation," issued January 17, 2012

The Invention Explained

• Problem Addressed: The patent background describes the competing concerns of security, cost, and convenience in electronic transaction systems. It notes that consumers often detect fraudulent transactions only when reviewing bills, days or weeks later, and that managing multiple payment instruments (credit, debit, gift cards) is cumbersome (’368 Patent, col. 1:46-68).
• The Patented Solution: The invention proposes an "intermediary service" that sits between the transaction acquirer (the merchant's financial institution) and the issuing institution (the customer's bank) (’368 Patent, col. 2:36-41). When a customer initiates a purchase with a token, the intermediary service sends a notification to the customer's mobile device. This out-of-band communication allows the customer to confirm or deny the transaction in near real-time and, in some cases, select which of their payment instruments to use, thereby enhancing security and flexibility (’368 Patent, Abstract; col. 2:41-50).
• Technical Importance: This method sought to reduce payment fraud by adding a real-time, user-involved verification step, particularly for "card not present" transactions, while also simplifying the consumer's ability to manage multiple payment accounts through a single interface on their mobile device (’368 Patent, col. 2:45-50, 61-68).

Key Claims at a Glance

• The complaint asserts claims 1-29, which includes independent claims 1 (method) and 14 (system) (Compl. ¶9).
• Independent Claim 1 (Method) includes the following essential elements:
  • Receiving an authorization request from a requester (e.g., an acquirer).
  • Authenticating the request.
  • Retrieving stored customer information, including data for "multiple payment instruments" and a mobile device address.
  • Generating and transmitting a message to the customer's mobile device that includes information about the transaction and "allows a selection of a payment instrument from at least two of the multiple payment instruments."
  • Receiving a confirmation message from the mobile device that "includes a selected payment instrument."
  • Obtaining the corresponding customer account information from the appropriate issuing institution.
  • Providing the obtained account information to the requester to complete the transaction.
• Independent Claim 14 (System) includes the following essential elements:
  • A "requester communication module" to receive an initial authorization request.
  • An "authentication module" to authenticate the requester.
  • A "customer management module" to retrieve customer information, including mobile device data and multiple payment instruments.
  • A "mobile device communication module" to send a notification and receive a confirmation that allows a customer to select a payment instrument.
  • An "issuer communication module" to obtain account information from an issuer based on the customer's selection.
• The complaint reserves the right to assert dependent claims (Compl. ¶9).

III. The Accused Instrumentality

Product Identification

The complaint does not name any specific accused products or services. It refers generally to "systems, products, and services" that Defendant Fiserv "maintains, operates, and administers" for processing financial transaction data (Compl. ¶9).

Functionality and Market Context

The complaint alleges that the accused instrumentalities are "methods and systems for processing financial transaction data in a server including a processor and an associated storage area" (Compl. ¶8). No specific technical details about how the accused systems operate are provided. The complaint also makes no allegations regarding the specific commercial importance or market positioning of the accused functionalities.

IV. Analysis of Infringement Allegations

The complaint alleges that Fiserv’s systems directly infringe, induce infringement of, and contribute to the infringement of claims 1-29 of the ’368 Patent (Compl. ¶¶9, 11, 12). However, it provides no specific factual allegations to support a detailed infringement theory. Instead, the complaint states that "Support for the allegations of infringement may be found in the the chart attached as Exhibit B," but this exhibit was not filed with the complaint and is not publicly available (Compl. ¶10).

Without the referenced claim chart or a narrative explanation of the infringement theory, the complaint offers only conclusory statements that Fiserv's unspecified systems perform the functions claimed in the patent. It does not explain, for example, how Fiserv's systems allegedly use a mobile device for out-of-band confirmation or allow for the selection of a payment instrument as required by the independent claims.

• Identified Points of Contention:
  • Architectural Question: A primary issue may be whether Fiserv's systems function as an "intermediary service" that is distinct from the acquirer and issuing institution, as depicted in the patent's figures (’368 Patent, Fig. 2A), or if its functionalities are integrated within a conventional transaction processing architecture.
  • Functional Question: The court will likely require evidence demonstrating that an accused Fiserv system performs the core claimed function: sending a pre-authorization notification to a user's mobile device that "allows a selection of a payment instrument from at least two of the multiple payment instruments" (’368 Patent, col. 20:38-44). The complaint provides no factual basis to suggest this functionality exists in any Fiserv product.
• No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

• The Term: "intermediary service"

  • Context and Importance: This term defines the fundamental architecture of the claimed invention. The outcome of the case may depend on whether Fiserv's accused systems can be characterized as performing the role of this "intermediary service." Practitioners may focus on this term to dispute whether the accused systems are structurally and functionally equivalent to the claimed invention.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification states the service "operates as an intermediary, between acquirers of financial transaction requests and issuing institutions" (’368 Patent, col. 2:36-39). A party could argue this language is functional and covers any system that logically sits between these entities, regardless of its specific implementation or ownership.
    • Evidence for a Narrower Interpretation: The patent figures consistently show the "Intermediary Service" (204) as a separate and distinct entity from the "Acquirer" (108) and "Issuing Institution" (110) (’368 Patent, Figs. 2A-2C). This could support a narrower construction requiring a technologically or commercially distinct third-party platform, not merely an integrated feature of an acquirer's or issuer's existing system.

• The Term: "a selection of a payment instrument from at least two of the multiple payment instruments"

  • Context and Importance: This limitation appears in independent claims 1 and 14 and describes a key user interaction. The infringement analysis will turn on whether any accused system provides this specific, per-transaction choice to the user on their mobile device.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: A party might argue that any system that allows a user to manage and set a default from multiple payment options, even if not on a per-transaction basis, satisfies the "selection" requirement.
    • Evidence for a Narrower Interpretation: The specification provides a specific example of this feature in Figure 3D, which depicts a transaction confirmation screen on a mobile device with a "drop-down menu 244 that allows the customer to affirmatively select the desired payment instrument" for that particular transaction (’368 Patent, col. 8:30-35). This suggests the claim requires an active, real-time choice for each transaction, not merely a pre-configured preference.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement by asserting that Fiserv "actively encouraged or instructed others (e.g., its customers...)" to use its products in an infringing manner (Compl. ¶11). It alleges contributory infringement by claiming there are "no substantial noninfringing uses for Defendant's products and services" (Compl. ¶12). These allegations are not supported by specific facts.
• Willful Infringement: Willfulness is alleged based on Fiserv’s knowledge of the ’368 patent "from at least the filing date of the lawsuit" (Compl. ¶¶ 11, 12). Plaintiff explicitly reserves the right to amend the complaint to allege pre-suit knowledge if it is discovered (Compl. ¶11 n.1, ¶12 n.2).

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

• A core issue will be one of architectural scope: can the claimed "intermediary service," which the patent depicts as a distinct entity, be construed to read on the functionality of Fiserv's potentially integrated financial processing systems? The patent's consistent visual separation of the intermediary from acquirers and issuers raises a significant question about the required system structure.
• A key evidentiary question will be one of functional proof: can Plaintiff provide evidence that any Fiserv system performs the central claimed method step of allowing a user to make "a selection of a payment instrument from at least two" options on their mobile device as part of a real-time, out-of-band authorization process? The complaint's complete lack of factual allegations on this point suggests this will be a primary focus of discovery and dispositive motions.
