1. Case Identification

2. Patent Overview

  • Title: Method and System for Smartphone-Based Financial Transactions
  • Brief Description: The ’743 patent discloses a method for a smartphone to establish a capability to conduct a financial transaction. The method involves sensing a parameter value that satisfies a criterion (e.g., biometric data), which then triggers selectively establishing a master-slave relationship and requesting/receiving authorization to enable the transaction capability.

3. Grounds for Unpatentability

Ground 1: Claims 1-14 are obvious over Jain

  • Prior Art Relied Upon: Jain (Application # 2009/0069049).
  • Core Argument for this Ground:
    • Prior Art Mapping: Petitioner argued that Jain discloses a system where a smartphone establishes a capability to conduct financial transactions. The limitation of "sensing a value of a parameter" is met by Jain’s disclosure of user authentication via PIN entry or biometrics (e.g., fingerprint). The "master-slave relationship" is met by the relationship between the financial institution (master), which controls transaction activation, and the mobile device (slave). The steps of "requesting" and "receiving authorization" are disclosed as the mobile device wirelessly transmitting a request for an activation code to the financial institution and receiving it in response. Jain’s disclosure of cellular and Wi-Fi communications, combined with a POSITA's motivation to use modern standards like LTE, meets the protocol requirements of claim 1[c], which rely on Orthogonal Frequency Division Multiplexing (OFDM) and Orthogonal Frequency Division Multiple Access (OFDMA). Dependent claims are met by, for example, Jain's disclosure of repeated authentication as an obvious security measure (claim 2) and NFC for proximity-based payments (claim 3).
    • Motivation to Combine: Although a single-reference ground, Petitioner presented it as an obviousness challenge. The primary motivation argued was for a POSITA to implement Jain’s teachings using well-known and more advanced technologies for security and performance. For instance, a POSITA would be motivated to repeatedly perform Jain's user authentication process to prevent fraud if a device becomes idle or re-locks. Similarly, a POSITA would be motivated to use contemporary high-performance cellular technologies like LTE or WiMAX, which inherently use the protocols recited in claim 1[c].
    • Expectation of Success: Petitioner asserted a POSITA would have a high expectation of success in implementing these modifications, as they involved applying conventional security measures and well-established, standardized wireless protocols to Jain's known system for mobile payments.

Ground 2: Claims 1-14 are obvious over Dua

  • Prior Art Relied Upon: Dua (Application # 2006/0165060).
  • Core Argument for this Ground: Petitioner argued Dua discloses the claimed invention under two alternative theories: a "Card-Issuing Theory" and an "External-Storage-Authentication Theory."
    • Prior Art Mapping:
      • Under the Card-Issuing Theory, a capability is established when a user is issued a new credit card credential to a wallet application. Dua’s requirement for PIN or biometric authentication to open the wallet meets the "sensing a parameter" limitation. A "master-slave relationship" is established between the issuer’s Wireless Credential Manager (WCM) (master) and the user's device (slave). The device "requests authorization" by sending a special code to the WCM and "receives authorization" when the WCM transmits the new credential back to the wallet.
      • Under the External-Storage-Authentication Theory, the capability is established by retrieving credentials from a remote storage service. The "sensing a parameter" is met when the device detects a "reader key" from a point-of-sale terminal. This triggers a "master-slave relationship" with the external storage service (master), from which the device "requests authorization" (e.g., by sending a username/password) and "receives authorization" in the form of credential information.
      • For both theories, Dua’s disclosure of various wireless protocols (including 802.11a/g which use OFDM) and the motivation to use modern standards like LTE meets the protocol limitations.
    • Motivation to Combine: Petitioner argued a POSITA would have been motivated to modify Dua to enhance security. For example, it would be obvious to require repeated authentication (e.g., PIN or biometric) before each transaction to reduce the risk of misuse if a device were lost or stolen, thereby satisfying the limitations of claim 2.
    • Expectation of Success: Petitioner contended a POSITA would have reasonably expected success in implementing such modifications, as they involved applying known authentication methods to a system already designed for secure mobile transactions.

4. Arguments Regarding Discretionary Denial

  • Petitioner argued against discretionary denial under both 35 U.S.C. §325(d) and the Fintiv factors.
    • §325(d): Petitioner asserted that Jain was never considered by the USPTO during prosecution. While Dua was cited, it was relied upon for rejections of claims with different limitations in related patents, and the examiner seemingly overlooked Dua’s key disclosures regarding biometric technologies, which Petitioner’s new arguments and expert analysis now highlight.
    • Fintiv Factors: Petitioner argued that the parallel district court litigation is in its earliest stages, with only initial pleadings served and no claim construction, depositions, or expert reports. Further, Petitioner stipulated that if the IPR is instituted, it will not pursue in district court any invalidity ground raised or that could have been reasonably raised in the petition. These factors, Petitioner contended, weigh heavily against discretionary denial.

5. Relief Requested

  • Petitioner requests institution of an inter partes review and cancellation of claims 1-14 of the ’743 patent as unpatentable.
