1. Case Identification

2. Patent Overview

  • Title: System and Method for Transmission of Data
  • Brief Description: The ’803 patent discloses a system for providing message notifications to remote computing devices that may be online or offline. The system uses a central broadcast server to receive data from various information sources, preprocess the data into data blocks, and transmit the blocks over a separate wireless broadcast network, such as a pager network, to a receiver connected to the user's device.

3. Grounds for Unpatentability

Ground 1: Obviousness over Hays and Pepe - Claims 1-4, 6, 8-10, 16, 23, 29, 36, and 37 are obvious over Hays in view of Pepe.

  • Prior Art Relied Upon: Hays (Application # 08/215,817) and Pepe (Patent 5,742,905).
  • Core Argument for this Ground:
    • Prior Art Mapping: Petitioner argued that Hays discloses the core framework of the ’803 patent. Hays teaches a telecommunication system that transmits messages to a mobile unit via two channels: a cellular connection and a separate paging channel. This system notifies a user of a waiting message via the paging channel, regardless of whether the cellular connection is online or offline. Petitioner asserted that Hays’s “message manager” and “Universal Messaging System” together function as the claimed “central broadcast server” that receives data, prepares it for transmission, and broadcasts it to remote devices. Pepe, which describes a personal communications interface for routing emails to pagers, was argued to supply the limitations of parsing data and using a subscriber database to format and route messages, which are only implicitly suggested in Hays.
    • Motivation to Combine: Petitioner contended that a person of ordinary skill in the art (POSITA) would combine Hays and Pepe. Both references address the same technical field of dual-mode cellular and pager messaging, were filed contemporaneously, and share the same international patent classification. A POSITA would have been motivated to integrate Pepe’s explicit message translation and subscriber database features into Hays’s dual-channel notification system to improve message handling and routing efficiency.
    • Expectation of Success: A POSITA would have had a reasonable expectation of success in combining these systems, as it involved applying known message processing techniques (from Pepe) to a known dual-channel communication architecture (from Hays).

Ground 2: Obviousness over Hays, Pepe, and Throckmorton - Claims 5, 7, 11-15, 17-22, 24-28, and 30-35 are obvious over the combination of Hays, Pepe, and Throckmorton.

  • Prior Art Relied Upon: Hays (Application # 08/215,817), Pepe (Patent 5,742,905), and Throckmorton (Patent 5,818,441).
  • Core Argument for this Ground:
    • Prior Art Mapping: This ground builds upon the Hays and Pepe combination by adding Throckmorton to address limitations in other dependent claims. Petitioner asserted that Throckmorton teaches a system for transmitting additional data (including URLs) associated with a primary broadcast, such as a television signal. This "associated data" provides pointers to secondary information sources. The key teachings from Throckmorton used to supplement Hays and Pepe include: using URLs and other Internet addresses in messages (for claims 24, 25); transmitting data blocks via wired transmission (for claim 5); and launching a viewer or browser in response to user interaction with an alert (for claims 12, 18).
    • Motivation to Combine: Petitioner argued a POSITA would be motivated to combine Throckmorton with the Hays/Pepe system because both Hays and Throckmorton teach systems with multiple communication paths that provide a user with a notification and a method to obtain more detailed information. Combining them would predictably result in an enhanced notification system that uses URLs and other commands within Hays's message structure to provide users with direct links to more content.
    • Expectation of Success: The combination would have been straightforward, involving the integration of known data types (URLs from Throckmorton) into the existing message payloads of the Hays system.

Ground 3: Anticipation by Kane - Claims 1-4, 8-10, and 37 are anticipated by Kane.

  • Prior Art Relied Upon: Kane (Patent 5,487,100).
  • Core Argument for this Ground:
    • Prior Art Mapping: Petitioner argued that Kane discloses every element of the challenged independent and dependent claims. Kane describes a system for transmitting information to a user's computer via two distinct paths: a wireless paging network ("Path B") for notifications and a dial-up PSTN connection ("Path A") for data retrieval. Petitioner contended that Kane’s “central terminal” is the claimed “central broadcast server,” which receives email messages from an X.400 network (the "information source"). The central terminal preprocesses messages by creating a "message record," parsing it to extract data, and building new data blocks for transmission. It uses a subscriber database to convert email addresses to pager addresses. The system then transmits a notification (e.g., a truncated message) over the wireless pager network, informing the user of the message regardless of whether the user’s dial-up connection is online or offline.
  • Additional Grounds: Petitioner asserted additional obviousness challenges, including grounds that claims 6-7, 13-14, 29-31, and 36 are obvious over Kane, and that claims 5, 11-12, 15-28, and 32-35 are obvious over Kane in view of Throckmorton.

4. Key Claim Construction Positions

  • "data channel associated with each device": This term was central to the invalidity arguments. Petitioner proposed the construction "a path through which the remote computing device connects to the Internet or other online service." This broad construction was argued to be met by the prior art’s disclosure of cellular data or dial-up PSTN connections, which provide a path to online services, separate from the primary notification channel (e.g., the pager network).
  • "information gateway" / "transmission gateway": Petitioner argued these terms, which Patent Owner construed as software programs performing specific functions, should be interpreted under the broadest reasonable interpretation standard. Petitioner contended that software functionalities disclosed in the prior art for building data blocks/assigning addresses (information gateway) and preparing data for broadcast (transmission gateway) met these limitations, even if not explicitly named as such.

5. Relief Requested

  • Petitioner requested institution of an inter partes review and cancellation of claims 1-37 of the ’803 patent as unpatentable.
