Case Timeline

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

U.S. Patent No. 9,245,270 - "Transaction Security Apparatus and Method," Issued January 26, 2016

The Invention Explained

• Problem Addressed: The patent family addresses shortcomings in conventional financial security practices at the time of invention, where account holders were typically notified of unauthorized transactions days or weeks after they occurred, often via a monthly statement (Compl. ¶ 31, citing shared specification language from ’429 Patent at 4:9-12). This delay limited the ability to prevent or mitigate fraud. Additionally, existing surveillance systems were not integrated with back-end transaction data, restricting their effectiveness in tying video evidence to specific fraudulent events (Compl. ¶ 29).
• The Patented Solution: The invention proposes an apparatus that integrates image capture with the transaction process. The system is designed to capture a photograph of the individual conducting a transaction, generate a notification message containing transaction details, and transmit both the message and the photograph to the account holder's communication device (e.g., a mobile phone) independently of the computer that authorizes the transaction itself (’270 Patent, Abstract). This provides the account holder with immediate awareness of account activity, enabling a rapid response to potential fraud (Compl. ¶ 32, citing shared specification language from ’429 Patent at 4:66-5:8).
• Technical Importance: The complaint alleges that integrating real-time video capture with back-end processing systems and providing immediate notifications to account holders was an unconventional technological advancement that improved card security (Compl. ¶¶ 29, 35).

Key Claims at a Glance

• The complaint asserts independent Claim 61 (Compl. ¶ 44).
• Essential Elements of Independent Claim 61:
  • An apparatus having a camera for obtaining a photograph or a picture of an individual involved in a transaction on an account.
  • An input device for inputting or entering, or a receiver for receiving, information regarding the transaction.
  • A processing device for processing the information regarding the transaction, wherein the processing device is adapted for generating a notification message containing information regarding the transaction.
  • A transmitter for transmitting the notification message to a communication device associated with an individual account holder independently of any processing of the transaction by a transaction authorization processing computer.
  • Wherein the transmitter or the apparatus is adapted to transmit the photograph or the picture to the communication device independently of any processing of the transaction by the transaction authorization processing computer.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

U.S. Patent No. 10,861,020 - "Transaction Security Apparatus and Method," Issued December 8, 2020

The Invention Explained

• Problem Addressed: The patent describes a financial system environment where transaction authorization practices fail to provide notice to a cardholder before, during, or shortly after a transaction, which is described as essential for preventing fraudulent use of a card or account number (’020 Patent, col. 4:36-51). Conventional systems lacked an apparatus to provide notification to an account owner at the time of an unauthorized transaction at an ATM (’020 Patent, col. 4:23-30).
• The Patented Solution: The patented solution is an apparatus comprising a transaction terminal (e.g., an ATM) with an integrated camera that obtains a photograph or video clip of the individual involved in the transaction. The system includes a back-end computer with a database that stores the image/video clip in association with the corresponding transaction information. This linked information is then transmitted to a communication device, independent of the transaction authorization processing computer (’020 Patent, Abstract). Figure 4 of the patent illustrates the system architecture, showing the banking transaction terminal (102) communicating with a central processing computer (103), which in turn communicates with the user's various devices (105-113) (’020 Patent, Fig. 4).
• Technical Importance: The complaint characterizes the invention as overcoming deficient conventional approaches by creating an unconventional system architecture that links visual evidence with specific transaction data for enhanced security (Compl. ¶¶ 32, 35).

Key Claims at a Glance

• The complaint asserts independent Claim 2 (Compl. ¶ 60).
• Essential Elements of Independent Claim 2:
  • An apparatus comprising a transaction terminal with an input device or receiver for receiving account and transaction information.
  • A camera or video recording device that obtains or records a photograph or video clip of an individual involved in the transaction.
  • A processor that processes the transaction information.
  • A computer comprising a database that stores information regarding the transaction and the photograph or video clip.
  • Hardware and software for transmitting the information and the photograph/video clip to a communication device independently of any processing by a transaction authorization processing computer.
  • Wherein the camera of the video recording device is located on the transaction terminal.
• The complaint does not explicitly reserve the right to assert dependent claims for this patent.

Multi-Patent Capsule: U.S. Patent No. 11,922,429

• Patent Identification: U.S. Patent No. 11,922,429, "Transaction Security Apparatus and Method," Issued March 5, 2024.
• Technology Synopsis: This patent describes a secure banking transaction system that links a transaction terminal to a central financial computer. The system addresses delays in fraud detection by capturing an image of the user during a transaction, storing it in a database associated with transaction data, transmitting real-time notifications to the account holder, and providing an interface for the financial institution to retrieve and display the linked image and transaction data for review (Compl. ¶¶ 81-94).
• Asserted Claims: The complaint asserts independent Claims 41 and 48 (Compl. ¶ 78).
• Accused Features: The complaint accuses Frost Bank's ATM network, which allegedly comprises banking terminals with cameras, user input devices, and card readers, connected to a central processing computer with a database. This system is alleged to store image and transaction data, generate and transmit notification messages, and allow for retrieval of the linked data by bank operators (Compl. ¶¶ 79-98).

III. The Accused Instrumentality

• Product Identification: The Accused Instrumentalities are systems comprising Frost Bank's branded ATMs, their associated hardware and software, and the back-end computer systems that monitor, process, and review transaction data (Compl. ¶ 41).
• Functionality and Market Context: The complaint alleges that the accused systems are comprised of a network of ATMs equipped with integral cameras for video and/or still image surveillance (Compl. ¶¶ 8, 45). The complaint provides a photograph of an exemplary Frost ATM in Plano, Texas, highlighting the location of a built-in camera (Compl. ¶ 45; Figure Group A, p. 17). The back-end systems are alleged to process transactions and generate electronic notifications, such as text or email alerts, to account holders regarding transactions conducted at these ATMs (Compl. ¶ 49). The complaint includes screenshots from Frost Bank's website detailing its "Debit Card Alerts" service, which allows customers to receive alerts for activities such as "ATM withdrawals" (Compl. ¶ 49; Figure Group C, p. 19). The complaint alleges these security features are part of standard industry practice to protect customers (Compl. ¶ 11).

IV. Analysis of Infringement Allegations

’270 Patent Infringement Allegations

’020 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central dispute may arise over the term "independently of any processing of the transaction by a transaction authorization processing computer." The complaint alleges this independence for both the notification message and the image transmission (Compl. ¶¶ 51, 53, 69). The case may turn on whether Frost’s alert system is architecturally separate from its transaction authorization system, or if it is a module that operates after authorization is complete but is still part of the same overall processing flow.
  • Technical Questions: What evidence does the complaint provide that the accused system transmits the photograph or video clip to an external communication device, as required by Claim 61 of the ’270 Patent and suggested by Claim 2 of the ’020 Patent? The complaint alleges the system is "configured and adapted" to do so (Compl. ¶ 53) but the provided visual evidence only documents text-based alerts for transaction details (Compl., Figure Group C, p. 19). The complaint also maps the "communication device" in the ’020 Patent's claim to internal "proprietary Frost interfaces" for fraud investigations (Compl. ¶ 69), which raises a question of whether this internal system meets the claim's requirements.

V. Key Claim Terms for Construction

• The Term: "independently of any processing of the transaction by a transaction authorization processing computer"
• Context and Importance: This limitation, present in the asserted claims of both the '270 and '020 patents, is central to the infringement theory. Its construction will likely determine whether the architecture of the accused system infringes. Practitioners may focus on this term because the defendant could argue its notification system, while separate in time, is not architecturally "independent" but rather a dependent, post-authorization function of the same overall financial processing system.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification contrasts the invention with prior art systems that were limited to the authorization process itself, suggesting "independently" could mean functionally separate from the approval or denial step. Language describing overcoming "shortcomings of the prior art" focuses on adding a notification layer that did not previously exist, which may support a construction that does not require complete physical or logical system separation ('020 Patent, col. 4:52-60).
  • Evidence for a Narrower Interpretation: Patent drawings such as Figure 1 depict the "CENTRAL PROCESSING COMPUTER" (3) as a distinct block from which communications are sent separately to the point-of-sale terminal and to the user's communication device ('020 Patent, Fig. 1). This could support an interpretation requiring structural, not just functional, independence.

VI. Other Allegations

• Willful Infringement: The complaint alleges that to the extent Defendant's infringement has continued after receiving notice of the patents, such infringement is "necessarily willful and deliberate" (Compl. ¶¶ 56, 74, 100). The basis for willfulness appears to be knowledge of the patents gained from the filing of the complaint itself, as no pre-suit notice is alleged.

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

• A core issue will be one of architectural configuration: does Frost Bank’s transaction alert system operate "independently" of its transaction authorization computer, as required by the claims? Resolution will likely depend on factual discovery into the design and data flows of the accused back-end systems.
• A key evidentiary question will be one of functional scope: does the accused system transmit, or is it merely capable of transmitting, the photograph or video clip of the user to a "communication device" as recited in the asserted claims? The complaint alleges this capability but provides direct evidence primarily for text-based transaction alerts.
