Case Timeline

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

• Patent Identification: U.S. Patent No. 8,099,368, Intermediary service and method for processing financial transaction data with mobile device confirmation, issued January 17, 2012. (Compl. ¶7).

The Invention Explained

• Problem Addressed: The patent background describes the difficulty in balancing security, cost, and convenience in electronic payment systems. It notes that detecting fraudulent or erroneous transactions often relies on inconvenient, post-hoc review of billing statements, and that consumers find managing multiple different payment cards cumbersome. ('368 Patent, col. 1:18-68).
• The Patented Solution: The invention introduces an "intermediary service" that operates between acquirers (who process merchant transactions) and issuing institutions (who issue payment cards). When a transaction is initiated, this service sends a notification to the customer's mobile device. This creates an out-of-band channel for the customer to confirm or deny the transaction in real-time. The service also allows the customer to manage and select from multiple registered payment instruments via their mobile device during the confirmation process. ('368 Patent, Abstract; col. 2:36-51).
• Technical Importance: The described technology aims to reduce fraud by requiring real-time user verification, while also providing a centralized point of control for a consumer's various payment methods. ('368 Patent, col. 2:45-51).

Key Claims at a Glance

• The complaint asserts infringement of claims 1-29. (Compl. ¶9). The lead independent claims are 1 (method), 14 (system), and 21 (method).
• Independent Claim 1 recites a method comprising the core steps of:
  • receiving an authorization request from a requester;
  • authenticating the request;
  • retrieving customer information from storage, including data defining multiple payment instruments and a mobile device address;
  • generating a transaction message for the mobile device that specifies a response allowing a selection of a payment instrument from at least two of the options;
  • transmitting the message and receiving a confirmation message back that includes a selected payment instrument;
  • obtaining account information for the selected instrument from an issuing institution; and
  • providing that account information to the requester. ('368 Patent, col. 19:22-20:5).
• The complaint asserts infringement of all claims 1-29, which includes all dependent claims. (Compl. ¶9).

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any specific products or services by name. It broadly accuses Defendant’s "systems, products, and services" used for "processing financial transaction data in a server including a processor and an associated storage area." (Compl. ¶9, ¶11).

Functionality and Market Context

• The complaint alleges that Fiserv "maintains, operates, and administers" systems that practice the claimed inventions and from which it derives "monetary and commercial benefit." (Compl. ¶9). However, the complaint does not provide specific details on the architecture, features, or operation of the accused instrumentalities, nor does it detail their market position.

IV. Analysis of Infringement Allegations

The complaint references a claim chart attached as Exhibit B to support its infringement allegations; however, this exhibit was not provided with the complaint. (Compl. ¶10). The infringement theory, based on the complaint's narrative, is that Fiserv's unidentified financial processing systems perform the role of the claimed "intermediary service." (Compl. ¶8). These systems are alleged to receive transaction requests and interact with a consumer's mobile device to confirm the transaction before routing information to other entities in the payment ecosystem, thereby infringing the asserted claims. (Compl. ¶9). No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Technical Questions: A primary question will be evidentiary: What evidence does the complaint provide that Fiserv's systems perform the specific step of generating a message for a mobile device that "allows a selection of a payment instrument from at least two of the multiple payment instruments," as required by independent claim 1? The complaint lacks any specific allegations on how the accused systems facilitate this user choice.
  • Scope Questions: The patent specification consistently illustrates the "intermediary service" as an architecturally distinct entity from the "acquirer" and "issuing institution." A key question of scope will be whether Fiserv's systems, in their actual implementation, function as such a distinct intermediary, or whether their architecture is integrated in a manner that falls outside the claim's structural and functional boundaries.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for a full analysis of claim construction disputes. However, based on the patent, the following terms may be central to the case.

• The Term: "intermediary service"

• Context and Importance: This term defines the core entity performing the patented method. The case will depend on whether Fiserv's accused systems can be properly characterized as this service. Practitioners may focus on this term because the patent’s figures and description consistently depict the "intermediary service" (204) as a discrete component operating between the acquirer (108) and the issuing institution (110). ('368 Patent, Figs. 2B, 2C; col. 2:36-39).

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The claims themselves do not explicitly state that the service must be a separate legal or corporate entity. An argument may be made that any system performing the recited functions infringes, regardless of its integration with other payment processing functions.
  • Evidence for a Narrower Interpretation: The specification’s repeated depiction of the "intermediary service" as a distinct block in system diagrams may support a narrower construction requiring a degree of architectural or functional separation from the acquirer and issuing institution. ('368 Patent, col. 2:36-39, "A transaction processing service that operates as an intermediary, between acquirers... and issuing institutions...").

• The Term: "response that allows a selection of a payment instrument"

• Context and Importance: This language in claim 1 requires more than a simple confirmation; it requires the ability for the user to choose a payment method. Proving this functionality in the accused systems will be critical to Plaintiff's case.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A party might argue this language covers any workflow where a transaction notification prompts a user to open an application and change a payment method before the transaction is finalized.
  • Evidence for a Narrower Interpretation: Figure 3D and its accompanying description show a specific user interface where a drop-down menu (244) is presented directly within the transaction confirmation message, allowing for immediate selection. ('368 Patent, Fig. 3D; col. 8:30-43). This could support a narrower construction requiring the selection mechanism to be an integrated part of the notification itself.

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement. It asserts that Fiserv encourages its customers to use its services in an infringing manner and that there are no substantial non-infringing uses for the accused services. (Compl. ¶11-12). Knowledge is alleged to exist "from at least the filing date of the lawsuit." (Compl. ¶11, fn. 1; ¶12, fn. 2).
• Willful Infringement: The complaint seeks a finding of willful infringement and treble damages, based on the allegation of knowledge of the patent and its infringement from the filing of the complaint onward. (Compl. ¶(e)).

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

• A central issue will be one of evidentiary sufficiency: Can the plaintiff produce discovery evidence to show that Fiserv's broadly accused systems actually perform every step of the asserted claims, especially the specific, claimed functionality of enabling a user to select from multiple payment instruments via a mobile device as part of a real-time transaction authorization?
• The case will also likely involve a question of architectural mapping: Does the technical architecture of Fiserv's payment processing systems align with the claimed "intermediary service," or does it operate in a way that is structurally and functionally distinct from the system described and claimed in the '368 patent?
• A key procedural question will relate to knowledge and willfulness: Since the complaint alleges knowledge only from the date of its filing, the viability of claims for pre-suit indirect infringement damages and the strength of the willfulness claim will depend entirely on whether Plaintiff can uncover evidence of pre-suit notice or willful blindness.
