• Case #: IPR2021-01077
• Patent #: 10,621,559
• Filed: July 21, 2021
• Petitioner(s): PNC Bank, N.A.
• Patent Owner(s): United Services Automobile Association
• Challenged Claims: 1-18

2. Patent Overview

• Title: Remote Deposit Capture System
• Brief Description: The ’559 patent discloses a system for remote check deposit capture. The system comprises a mobile device for capturing a check image, a general-purpose computer, and a server at a financial institution that receives and processes the check image for deposit.

3. Grounds for Unpatentability

Ground I: Obviousness over Garcia, Randle, and Slater - Claims 1-3 and 10-12 are obvious over Garcia in view of Randle and Slater.

• Prior Art Relied Upon: Garcia (International Publication No. WO 2005/043857), Randle (Application # 2006/0106717), and Slater (European Application # 0984410).
• Core Argument for this Ground:
  • Prior Art Mapping: Petitioner argued that the independent claims' elements were disclosed across the three references. Garcia taught a front-end system where a user's mobile device captures and transmits a check image to a financial institution for processing. Randle taught a comprehensive back-end check processing system, including a payee bank, payor bank, and clearing house, which performs quality assurance, image format conversion, duplicate check detection, and MICR data processing. Slater taught a specific validation step where a system compares an OCR-scanned check amount with a customer-entered amount to confirm a match before proceeding.
  • Motivation to Combine: A Person of Ordinary Skill in the Art (POSITA) would combine Garcia's mobile front-end with Randle's well-known back-end processing architecture to create a complete and functional end-to-end remote deposit system. Because Garcia's system required amount validation, a POSITA would naturally look to known solutions like Slater's method of comparing OCR and user-entered amounts to improve system reliability and accuracy.
  • Expectation of Success: A POSITA would have a reasonable expectation of success, as combining a known mobile capture method (Garcia) with standard back-end processing (Randle) and a simple validation check (Slater) involved integrating predictable components to achieve the known result of remote check deposit.

Ground II: Obviousness over Garcia, Randle, Slater, and Lev - Claims 4, 9, 13, and 18 are obvious over the combination of Ground I in view of Lev.

• Prior Art Relied Upon: Garcia, Randle, Slater, and Lev (Application # 2006/0164682).
• Core Argument for this Ground:
  • Prior Art Mapping: This ground built upon the core combination in Ground I to address claims requiring user assistance and image editing. Lev taught an interactive system where a backend server provides real-time instructions to a user (e.g., "move camera to the right and closer please") to guide them in optimally capturing a document image. Lev also disclosed geometrically correcting an image's orientation and size, which corresponds to the claimed image rotation editing process.
  • Motivation to Combine: A POSITA would be motivated to incorporate Lev's interactive guidance and image correction into the Garcia/Randle/Slater system to solve the known problem of poor image quality from mobile device captures. Improving the initial image quality would predictably enhance the reliability of subsequent processing steps, such as OCR.
  • Expectation of Success: Integrating Lev's teachings was a predictable design choice. Since the base system already involved an interactive session between a mobile device and a server, adding Lev's user guidance prompts and image correction algorithms would be a straightforward improvement to yield better quality check images.

Ground III: Obviousness over Garcia, Randle, Slater, Lev, and Watanabe - Claims 5 and 14 are obvious over the combination of Ground II in view of Watanabe.

• Prior Art Relied Upon: Garcia, Randle, Slater, Lev, and Watanabe (Patent 7,027,171).

• Core Argument for this Ground:

  • Prior Art Mapping: This ground added Watanabe to address limitations requiring instructions to orient the check for capture. Watanabe taught a "document photographing mode" in a digital camera that displayed a "guidance frame" on the screen. This frame, based on a document's known aspect ratio, helped the user orient the document correctly within the camera's view before taking the picture.
  • Motivation to Combine: A POSITA, seeking to implement the user guidance taught by Lev, would have seen Watanabe's guidance frame as a known, specific, and effective method for ensuring proper check orientation. This would further improve the quality of the captured image and reduce errors caused by skewing and improper rotation.
  • Expectation of Success: Adding a visual guidance frame as taught by Watanabe to the interactive session of the Garcia/Lev combination would be a simple and predictable implementation of user-assistance functionality.

• Additional Grounds: Petitioner asserted additional obviousness challenges, including Ground IV (adding Aoyama for instructions on activating the capture device) and Ground V (adding Byrne for instructions on selecting a deposit account from a list), which relied on similar theories of combining known, discrete functionalities to improve a remote deposit system.

4. Key Claim Construction Positions

• "first processing circuitry" / "second processing circuitry": Petitioner argued that these terms should be construed as "first processor" and "processor different from the first processor," respectively. This construction supported Petitioner's argument that the distinct computer systems at the payee bank (e.g., in Randle) and the payor bank/clearing house could satisfy the two different circuitry limitations.
• Agreed/PO-Proposed Constructions: Petitioner relied on several agreed-upon constructions from co-pending litigation, such as "computing device" meaning "general purpose computer," and adopted the Patent Owner's proposed construction of "mobile device associated with an image capture device" as a "handheld computing device." Petitioner contended the claims were obvious under either party's proposed constructions for the disputed terms.

5. Arguments Regarding Discretionary Denial

• Petitioner argued against discretionary denial under Fintiv, stating that co-pending district court litigation was in its early stages, with no claim construction hearing scheduled and minimal investment in the merits of the invalidity positions.
• Petitioner stipulated that, if the IPR were instituted, it would not pursue the same grounds or any that could have been reasonably raised in the IPR before the district court, thus eliminating concerns of overlapping proceedings.
• The petition presented a strong challenge based on new prior art (Garcia) and new combinations never considered by the USPTO during prosecution or in prior post-grant challenges to related patents. Petitioner argued this factor weighed heavily against discretionary denial under §325(d).

6. Relief Requested

• Petitioner requested institution of an inter partes review and cancellation of claims 1-18 of the ’559 patent as unpatentable.
