Patent Number: US7509178B2
Title: Audio program distribution and playback system
Inventors: James D. Logan, Daniel F. Goessling, Charles G. Call
Current Assignee: Personal Audio LLC
Original Assignee: Individual
Filing Date: February 13, 2001 (for application US09/782,546)
Issue Date: March 24, 2009

Abstract:
An audio program player system that receives a scheduled sequence of program segments from a remote server and plays them in a listener-defined order. The system includes features for skipping segments, inserting dictated annotations, designating hypertext links and bookmarks, and dynamically altering the playing sequence and content based on listener commands. The player also creates and uploads a usage log to the remote server, enabling accounting functions like billing, content provider royalty payments, and marketing analysis.

Plain-Language Overview of Independent Claims:

  • Claim 1: This claim describes a method for playing audio programs. It involves a client system receiving a schedule of audio program segments from a server. The client system stores these segments, plays them according to a sequence, records how the listener uses the programs (a usage log), and sends this log back to the server. The server then uses this log to adjust future program schedules for the listener. The method also covers allowing the listener to interactively change the playing sequence and content, and the usage log tracks these changes.

  • Claim 8: This claim details a system for distributing audio programs to many client systems. It includes a server with a library of audio content and a database of user information and usage logs. The server uses this data to create personalized program schedules and send them to the clients. Each client system receives the schedule, stores the audio content, and plays it back. Crucially, the client system records how the user interacts with the content (e.g., what was played, skipped, or bookmarked) and uploads this usage log back to the server. The server then processes this log for various purposes like billing, content provider payments, and refining future schedules.

  • Claim 14: This claim is for a computer program product stored on a computer-readable medium. This program enables a client system to play audio programs. It allows the client system to receive a program schedule and audio segments from a server, store them, and play them back. The program records a log of program usage, including interactive changes made by the listener, and sends this log to the server. The server then uses this feedback to modify future program schedules for the listener.

  • Claim 17: This claim describes a system designed for dynamically and interactively selecting and playing programs from a library. It involves a server that sends a schedule of audio programs to a player. The player can play these programs and record the listener's actions, such as what they listened to, what they skipped, and any comments they made. This usage data is then sent back to the server. The server uses this information to create future program schedules that are tailored to the listener's preferences and past interactions.

USPTO and CAFC 2026 Dockets Search:

  • USPTO Status: The patent US7509178B2 is listed as "Expired - Fee Related," with an expiration date of June 27, 2018.
  • CAFC 2026 Dockets: A search of CAFC dockets for 2026 specifically for patent number 7509178 did not yield any results. The provided patent information does list past CAFC litigation, with the most recent case noted as "24-1020" (filed in 2024), but no active 2026 cases were found. There is no authoritative information about litigation for this specific patent in the CAFC in 2026.I apologize, the previous response did not include all the independent claims as listed in the full patent text from the provided Google Patents URL. I will correct this and provide a complete plain-language overview of all independent claims.

Revised Plan:

  1. Access the full patent text, specifically the claims, from the provided Google Patents URL. I will click the link and manually review the claims.
  2. Identify all independent claims (claims that do not refer to other claims).
  3. Provide a plain-language overview of each independent claim.
  4. Confirm USPTO status and CAFC 2026 dockets. (Already done in previous thought, confirmed no 2026 CAFC dockets and expired status).
  5. Compile the summary.

Let's re-examine the claims from the Google Patents page.

Claims 1, 8, 14, 17 were identified previously. I need to reconfirm if there are any other independent claims.

Looking at the claims section of US7509178B2 on Google Patents:

  • Claim 1: Independent

  • Claim 12: Depends on claim 8
  • Claim 13: Depends on claim 8
  • Claim 14: Independent
  • Claim 15: Depends on claim 14
  • Claim 16: Depends on claim 14
  • Claim 17: Independent
  • Claim 18: Depends on claim 17
  • Claim 19: Depends on claim 17
  • Claim 20: Depends on claim 17
  • Claim 21: Depends on claim 17
  • Claim 22: Depends on claim 17
  • Claim 23: Depends on claim 17
  • Claim 24: Depends on claim 17
  • Claim 25: Depends on claim 17
  • Claim 26: Depends on claim 17

Patent Number: US7509178B2
Title: Audio program distribution and playback system
Inventors: James D. Logan, Daniel F. Goessling, Charles G. Call
Current Assignee: Personal Audio LLC
Original Assignee: Individual
Filing Date: February 13, 2001 (for application US09/782,546)
Issue Date: March 24, 2009

Abstract:
An audio program player system which receives a scheduled sequence of program segments from a remote server, and plays the program segments in a listener-defined order, with facilities for skipping segments, inserting dictated annotations, designating hypertext links and bookmarks, and for otherwise dynamically altering the playing sequence and content in response to commands from a listener. The player also creates and uploads a log of usage to the remote server which enables accounting functions such as billing, content provider royalty payment and marketing analysis to be performed.

Plain-Language Overview of Independent Claims:

  • Claim 1: This claim describes a method for playing a scheduled sequence of audio program segments at a client system. It involves the client receiving a schedule of segments and the segments themselves from a remote server, storing them, and then playing them in a sequence. The listener can dynamically alter this sequence and content through commands. The client system also records a usage log of what was played and how the listener interacted with it, and this log is uploaded to the server for processing (e.g., for accounting or to modify future schedules).

  • Claim 8: This claim describes a system for distributing audio program segments to multiple client systems. The system includes a host server that stores audio content, user data, and usage logs. The server compiles scheduled sequences of audio segments tailored to individual subscribers based on their preferences and previous usage. Each client system is configured to receive and store these segments and schedules, play the audio, and then record and upload a usage log of the playback. The server uses these uploaded logs to dynamically generate future schedules.

  • Claim 14: This claim is directed to a computer program product stored on a computer-readable medium. The program enables a client system to perform the method of playing a scheduled sequence of audio program segments. This includes receiving and storing segments and a schedule from a server, playing the segments, allowing dynamic alteration of the playing sequence and content based on listener commands, and creating and uploading a usage log to the server so that the server can modify future program schedules.

  • Claim 17: This claim describes a system for interactively selecting and playing programs from a library. It comprises a server that transmits a schedule of audio program segments to a player. The player is equipped to play these segments and record a usage log, which captures information about the listener's interaction, such as played segments, skipped segments, and dictated annotations. This usage log is sent back to the server, which then processes it to create future program schedules that are customized to the listener's observed preferences and interactions.
