1. Case Identification

2. Patent Overview

  • Title: Adaptive Enablement of Communications Modes
  • Brief Description: The ’172 patent describes methods for adaptively enabling functions on a mobile device. The challenged claims are directed to a two-step method for conducting a financial transaction at a point of purchase, where a transaction capability is first enabled after sensing a user parameter (e.g., a physiological state), and the transaction is subsequently performed when the device detects proximity to a vendor's access point.

3. Grounds for Unpatentability

Ground 1: Claims 1-2, 4, 6-10, and 12-16 are obvious over Carlson in view of Holloway, Jazayeri, and ISO-14443.

  • Prior Art Relied Upon: Carlson (Patent 8,229,852), Holloway (WO 02/49322), Jazayeri (Application # 2008/0155268), and ISO-14443 (International Standard).
  • Core Argument for this Ground:
    • Prior Art Mapping: Petitioner argued that Carlson taught the foundational two-step process for a mobile financial transaction: (1) unlocking a device and requesting a temporary pseudo primary account identifier (PPAI) from a payment network, and (2) using that PPAI to pay at a merchant's contactless reader. However, Carlson only briefly mentioned using a fingerprint for unlocking and using NFC per the ISO-14443 standard, without providing implementation details. Petitioner contended that Holloway supplied the necessary teachings for a mobile device with an integrated fingerprint scanner, and Jazayeri provided the specific process for authenticating a user by comparing sensed fingerprint data against a stored template. This combination allegedly met the claim limitation of enabling a function responsive to sensing a parameter (a fingerprint, interpreted as a "physiological state"). ISO-14443 was used to supply the standard protocol details for the proximity-based NFC communication between the phone and the merchant's reader.
    • Motivation to Combine: A POSITA would combine Holloway and Jazayeri with Carlson to implement the fingerprint unlock feature that Carlson contemplated but did not detail, thereby increasing security in a predictable way. Because Carlson expressly suggested using the ISO-14443 standard for NFC, a POSITA would have been motivated to consult the standard itself to implement the short-range communication for the transaction.
    • Expectation of Success: Success was expected because fingerprint sensors were common, low-cost, and well-proven for mobile devices, as taught by Holloway. The components required were simple and readily integrated into a system like Carlson's.

Ground 2: Claims 3 and 11 are obvious over Carlson, Holloway, Jazayeri, and ISO-14443 in further view of Doyle.

  • Prior Art Relied Upon: Carlson (Patent 8,229,852), Holloway (WO 02/49322), Jazayeri (Application # 2008/0155268), ISO-14443 (International Standard), and Doyle (Application # 2002/0095586).
  • Core Argument for this Ground:
    • Prior Art Mapping: This ground targeted claims requiring the device to repeatedly sense the parameter to decide whether to maintain an enabled function. The base combination in Ground 1 did not teach this continuous monitoring. Petitioner asserted that Doyle remedied this deficiency by teaching a portable device with a biometric sensor (e.g., thumbprint scanner) capable of "repeatedly checking the user's identity during the entire period the device is in use" to maintain device functions.
    • Motivation to Combine: A POSITA would incorporate Doyle's teaching of continuous authentication into the system from Ground 1 to further enhance security. For a device used for financial transactions, maintaining security beyond the initial unlock is a recognized need, and continuous authentication was a known solution to this problem.
    • Expectation of Success: Doyle's teachings were applicable to any "pervasive computing device," including cell phones, and the necessary components for repetitive sensing were already present in the base combination.

Ground 3: Claims 1-2, 4, 6-10, and 12-16 are obvious over Carlson in view of Jazayeri, ISO-14443, and Murakami.

  • Prior Art Relied Upon: Carlson (Patent 8,229,852), Jazayeri (Application # 2008/0155268), ISO-14443 (International Standard), and Murakami (WO 01/95246).

  • Core Argument for this Ground:

    • Prior Art Mapping: This ground provided an alternative to Ground 1, based on a narrower interpretation of "physiological state" that is limited to dynamic, variable parameters, consistent with the patent's specification. Instead of using Holloway's static fingerprint scanner, Petitioner substituted Murakami. Murakami taught a mobile phone with a biometric sensor that authenticates a user based on physiological parameters like "blood flow, heart rate, [and] blood pressure" by analyzing a composite waveform. This directly taught sensing a dynamic physiological state, such as heart rate, which is an exemplary parameter listed in the ’172 patent itself.
    • Motivation to Combine: A POSITA seeking to implement biometric authentication in Carlson's system would have considered various known methods. Murakami provided a known alternative to fingerprint scanning that offered benefits such as increased user privacy and not requiring expensive scanning equipment. This approach aligned more closely with the ’172 patent's disclosure of dynamic parameters.
    • Expectation of Success: The biometric authentication technique in Murakami used simple, common components (e.g., memory, processor) that were already disclosed in Carlson's device, making integration straightforward.

  • Additional Grounds: Petitioner asserted additional obviousness challenges by adding Doyle (for repeated sensing) and Birch (for e-receipt functionality) to the Carlson/Murakami combination, mirroring the arguments in Grounds 2 and 3 but based on the narrower interpretation of "physiological state" as a dynamic parameter.

4. Key Claim Construction Positions

  • "Parameter" and "Physiological State": Petitioner dedicated significant argument to these terms. It contended that the patent’s specification, which lists examples like "blood pressure, a heart rate, a blood content," implies these terms refer to dynamic, variable parameters that fluctuate over time. This contrasts with the Patent Owner's alleged litigation position that static biometrics, such as a fingerprint or facial geometry, satisfy the limitation. Petitioner presented its grounds in two sets to address both interpretations.

5. Key Technical Contentions (Beyond Claim Construction)

  • Dual-Track Invalidity Argument: The petition's central strategy was to present two parallel sets of invalidity grounds based on the contested meaning of "physiological state."
    • Grounds 1-3 adopted the Patent Owner's broad interpretation, arguing that if a static fingerprint qualifies as a "physiological state," then prior art like Holloway rendered the claims obvious.
    • Grounds 4-6 adopted a narrower interpretation consistent with the patent's specification, arguing that even if the term is limited to dynamic physiological data, prior art like Murakami (teaching heart rate and blood flow sensing) still rendered the claims obvious.

6. Relief Requested

  • Petitioner requested institution of an inter partes review and cancellation of claims 1-16 of Patent 11,937,172 as unpatentable.
