Roku Inc v. Flexiworld Technologies Inc

1. Case Identification

• Case #: IPR2022-01268
• Patent #: 9,389,822
• Filed: July 29, 2022
• Petitioner(s): Roku, Inc.
• Patent Owner(s): Flexiworld Technologies, Inc.
• Challenged Claims: 17-25 and 39-44

2. Patent Overview

• Title: System and Method for Providing Digital Content
• Brief Description: The ’822 patent discloses a system for providing digital content from an information apparatus (e.g., a mobile device) to a separate output device. The specification primarily describes a wireless printing architecture where data formatting is offloaded from the resource-limited mobile device to a server, but the challenged claims are directed more broadly to retrieving and wirelessly outputting video content.

3. Grounds for Unpatentability

Ground 1: Obviousness over [Yukie](https://ai-lab.exparte.com/case/ptab/IPR2022-01268/doc/1005), [Ikonen](https://ai-lab.exparte.com/case/ptab/IPR2022-01268/doc/1006), [Ellis](https://ai-lab.exparte.com/case/ptab/IPR2022-01268/doc/1007), and [Lewis](https://ai-lab.exparte.com/case/ptab/IPR2022-01268/doc/1008) - Claims 17-25 and 39-44 are obvious over Yukie in view of Ikonen, Ellis, and Lewis.

• Prior Art Relied Upon: Yukie (Patent 7,644,018), Ikonen (Application # 2006/0112414), Ellis (Patent 6,774,926), and Lewis (Patent 6,526,506).
• Core Argument for this Ground:

  • Prior Art Mapping: Petitioner asserted that the prior art combination teaches all limitations of the challenged claims. Yukie was presented as the primary reference, disclosing a base system where a mobile user terminal (e.g., a PDA) with a client application and GUI requests and receives digital content, including video, from a server over the internet. The system involves user authentication and content selection via a toolbar.

  • To meet further limitations, Petitioner combined Yukie with three additional references. Ikonen was used to teach wirelessly transmitting content from the mobile device to a separate, superior output device, such as a television, via a link module. Ellis was cited to supply several well-known features for the mobile device described in Yukie, including a touch-sensitive screen, a scrolling GUI, an integrated digital camera, and the use of a standard video format like MPEG. Finally, Lewis was introduced to teach the specific use of the IEEE 802.11 standard for the wireless communication link taught by Ikonen and the associated security measure of obtaining a key to establish the connection.

  • For dependent claims, Petitioner argued that Ikonen taught the output device being a television (claim 19) and that Ellis’s disclosure of MPEG format rendered the decoding/encoding operations of claim 20 obvious. Yukie’s subscription-based service was argued to meet the limitations of sending payment or subscription information (claim 21).

  • Motivation to Combine: Petitioner argued a person of ordinary skill in the art (POSITA) would have been motivated to combine the references for predictable results.

    • A POSITA would combine Yukie and Ikonen to improve the user experience of Yukie’s system. Rather than viewing content on the small screen of Yukie’s mobile terminal, a POSITA would incorporate Ikonen’s wireless link to display the content on a larger, higher-quality television screen without the inconvenience of a wired connection.
    • A POSITA would incorporate the teachings of Ellis into the Yukie/Ikonen system because Ellis described features like touch screens and scrolling GUIs that were common and desirable for the types of handheld devices (PDAs, phones) that Yukie’s system utilized. Adding these features would be a simple matter of applying known technologies to improve usability.
    • A POSITA implementing the wireless LAN taught by Ikonen would naturally turn to the pervasive IEEE 802.11 standard, as taught by Lewis. Because wireless transmissions are susceptible to eavesdropping, a POSITA would also have been motivated to incorporate the security features taught by Lewis, such as using an authentication key, to secure the wireless link.

  • Expectation of Success: Petitioner contended a POSITA would have had a reasonable expectation of success. The technologies involved—video streaming, wireless LANs (including IEEE 802.11), touch screen interfaces, and MPEG video encoding—were all well-established and widely used by the patent’s priority date. Combining these known elements to create the claimed system would have been a straightforward integration yielding predictable results.

4. Arguments Regarding Discretionary Denial

• Petitioner argued that discretionary denial under 35 U.S.C. §314(a) based on Fintiv factors would be inappropriate. The parallel district court litigation was stayed by agreement of the parties pending a motion to dismiss, and no scheduling order had been entered. Petitioner asserted that even if a schedule were entered immediately, the earliest trial date would be in early 2024, concurrent with or after a potential Final Written Decision (FWD) in the inter partes review (IPR). Petitioner also stipulated that it would not pursue the same invalidity grounds in the district court litigation if the IPR is instituted.

5. Relief Requested

• Petitioner requests institution of an IPR and cancellation of claims 17-25 and 39-44 of the ’822 patent as unpatentable under 35 U.S.C. §103.
