1. Case Identification

2. Patent Overview

  • Title: Mobile Check Deposit Auto-Capture
  • Brief Description: The ’310 patent is directed to methods for remote check deposit using a mobile device. The system involves a downloadable application that generates a live video of a check, monitors the video feed against one or more criteria, and automatically captures a high-quality image for deposit when those criteria are satisfied.

3. Grounds for Unpatentability

Ground 1: Claims 1-3, 5-6, 8-12, and 14-16 are obvious over Garcia, Luo, Meier, and Cohen

  • Prior Art Relied Upon: Garcia (International Publication No. WO2005/043857), Luo (Chinese Application Publication No. CN 1897644A), Meier (a 2008 book on Android application development), and Cohen (Application # 2007/0194102).
  • Core Argument for this Ground:
    • Prior Art Mapping: Petitioner argued that the combination of these references taught every element of the challenged claims. Garcia disclosed the foundational method of remote check deposit using a mobile device to capture and transmit a check image to a financial institution. Luo taught improving image quality for optical character recognition (OCR) by using on-screen "reference lines" as an alignment guide and automatically capturing an image once the document was properly aligned. Meier, a guide for Android developers, taught the common and well-known software architecture for implementing such features, including using standard camera Application Programming Interfaces (APIs) to control a device camera, process live video, and package the functionality into a downloadable application. Finally, Cohen filled in implementation details that Garcia described as "usual means" for check processing, such as performing OCR, reading the magnetic ink character recognition (MICR) line, and validating the check amount with accuracy confidence levels.
    • Motivation to Combine: Petitioner asserted that a person of ordinary skill in the art (POSITA) would have been motivated to combine the references to solve known problems with predictable solutions. A POSITA starting with Garcia’s remote deposit system would naturally look to improve the quality of captured images, a common issue, and would find Luo’s teachings on alignment guides and auto-capture directly applicable. To implement this on a modern mobile platform, a POSITA would consult a standard guide like Meier, which provided the necessary instructions for creating a downloadable app that accesses the camera via APIs. A POSITA would also combine these teachings with a standard check processing system like Cohen’s to implement the back-end verification steps that Garcia’s system required.
    • Expectation of Success: A POSITA would have had a reasonable expectation of success because all references address the same field of mobile image capture and check processing. Combining Luo's image alignment techniques with Garcia's system was a predictable improvement, and using Meier's standard API-based approach was a well-known method for developing mobile applications with camera functionality.

Ground 2: Claims 4, 7, and 13 are obvious over Garcia, Luo, Meier, Cohen, and Yoon

  • Prior Art Relied Upon: Garcia (International Publication No. WO2005/043857), Luo (Chinese Application Publication No. CN 1897644A), Meier (a 2008 book), Cohen (Application # 2007/0194102), and Yoon (Application # 2007/0262148).

  • Core Argument for this Ground:

    • Prior Art Mapping: This ground builds upon the combination in Ground 1 to address dependent claims requiring monitoring criteria based on light brightness, skewing, and warping. While Luo taught monitoring for skew and warp (by detecting straight edges and reducing projective distortion), Yoon was added for its explicit teaching of using image brightness as a monitoring criterion for auto-capture. Yoon disclosed a system that converts camera sensor brightness into data, compares it to a reference value, and uses that determination as a criterion for automatically photographing a document.
    • Motivation to Combine: The motivation to add Yoon to the primary combination was to further enhance the quality and reliability of the captured check image. A POSITA would understand that poor lighting and insufficient brightness are common causes of low-quality images and failed OCR. It would have been obvious to incorporate an additional, known image-quality check, such as the brightness monitoring taught by Yoon, alongside the alignment and skew checks taught by Luo to create a more robust auto-capture system.
    • Expectation of Success: Combining multiple, independent image quality criteria (e.g., alignment, skew, brightness) was a well-known and predictable strategy for improving the performance of automated document capture systems. Yoon itself disclosed using reference lines in addition to brightness, confirming the compatibility of these techniques.

  • Additional Grounds: Petitioner asserted analogous obviousness challenges (Grounds III and IV) that mirrored the logic of Grounds 1 and 2, respectively. These grounds substituted Goyal (a 2006 guide on Java ME application development) for Meier, arguing a POSITA would have found it equally obvious to implement the claimed system using the Java ME mobile platform and its corresponding APIs, which provided functionally equivalent tools for creating downloadable, camera-enabled applications.

4. Relief Requested

  • Petitioner requests institution of an inter partes review and cancellation of claims 1-16 of the ’310 patent as unpatentable.
