1. Case Identification

2. Patent Overview

  • Title: Data Storage and Access Systems
  • Brief Description: The ’598 patent describes systems and methods for managing access to digital content on a portable data carrier. The technology aims to solve the problem of digital piracy by combining digital rights management (DRM) with content data storage, thereby linking data access and payment to prevent unauthorized use.

3. Grounds for Unpatentability

Ground 1: Ineligibility under §101 - Claim 7 is ineligible for patenting due to abstractness.

  • Prior Art Relied Upon: Not applicable.
  • Core Argument for this Ground:
    • Abstract Idea: Petitioner argued that claim 7 is directed to the abstract idea of enabling limited use of paid-for or licensed content. This fundamental economic practice, analogous to copyright management, can be performed mentally or with pen and paper, such as by a radio station operator managing licensed music playlists and reporting usage.
    • Lack of Inventive Concept: Petitioner asserted that the claim’s recitation of generic computer components—such as an "interface," "memory," a "program store," and a "processor"—does not transform the abstract idea into a patent-eligible application. These elements were described as conventional hardware performing their most basic functions, failing to add anything inventive to the underlying abstract concept.
    • Preemption: The petition contended that claim 7 is invalid because it preempts the entire field of managing access to paid-for content. By claiming the abstract idea and implementing it with generic computer components, the claim impermissibly monopolizes a fundamental concept without being tied to a specific, non-conventional machine or transformative process.

Ground 2: Obviousness over Gruse in view of Stefik - Claim 7 is obvious over Gruse in view of Stefik.

  • Prior Art Relied Upon: Gruse (WO 00/08909) and Stefik (Patent 5,530,235, incorporating Patent 5,629,980).
  • Core Argument for this Ground:
    • Prior Art Mapping: Petitioner asserted that Gruse taught a comprehensive system for the secure electronic distribution of digital content, including end-user devices, a clearinghouse for payment validation, and rights management based on usage conditions (use rules). Gruse explicitly mentioned that its end-user devices could include PCs that copy content to "portable, consumer devices." Stefik taught a portable "DocuCard" with an interface (e.g., PCMCIA), processor, and memories for securely storing and controlling access to digital works based on usage rights.
    • Motivation to Combine: Petitioner argued a person of ordinary skill in the art (POSITA) would combine these references to arrive at the claimed invention. Gruse disclosed the overall system architecture, including the concept of transferring content to a portable device, but did not detail the specific hardware or interface for such a device. A POSITA seeking to implement Gruse's system would have been motivated to consult contemporaneous art like Stefik for a known, secure, and advantageous portable device interface. Stefik’s DocuCard provided a concrete, off-the-shelf solution for the portable data carrier component suggested by Gruse.
    • Expectation of Success: A POSITA would have had a reasonable expectation of success in combining the references. The combination involved applying Stefik's well-understood portable device and standard interface technology (PCMCIA) to Gruse's compatible system architecture. This would have been a predictable integration of known elements to achieve the desired result of secure content management on a portable device.

4. Key Claim Construction Positions

  • "payment data": Petitioner proposed this term should be construed to mean "data that relates to previous, present, and/or prospective payment." This construction was argued to be consistent with the specification’s description of a payment validation system that validates payment made for data. This broad interpretation supported the contention that the patent claimed a fundamental financial practice, making it eligible for Covered Business Method (CBM) review.

5. Key Technical Contentions (Beyond Claim Construction)

  • Ineffective Priority Claim: A central contention was that the ’598 patent was not entitled to its claimed priority date of October 25, 1999. Petitioner argued that the priority application ('227.2 Appln.) failed to provide adequate written description support for key limitations in the challenged claim, including the separate storage of content data and use rules on the same portable carrier and the presence of a "payment data memory." Consequently, Petitioner argued the claim's effective filing date was no earlier than October 25, 2000, which rendered Gruse (published February 2000) and Stefik (issued 1996-1997) eligible as prior art references.

6. Arguments Regarding Discretionary Denial

  • CBM Eligibility: The petition presented substantial arguments that the ’598 patent was eligible for CBM review and not exempt as a "technological invention." Petitioner contended that at least one claim was directed to a financial product or service—specifically, a method for "paying for data." Furthermore, it was argued that the invention was not technological because the recited hardware components (processor, memory) were merely generic and conventional, used to automate a fundamental business practice without solving a technical problem with a technical solution.

7. Relief Requested

  • Petitioner requested the institution of a Covered Business Method patent review and the cancellation of claim 7 of the ’598 patent as unpatentable.
