Prior art

To identify the most relevant prior art for US patent 8156360, I will analyze each patent listed under the "Patent Citations" section of the provided patent text. For each reference, I will provide its full citation, publication/filing date, a brief description, and an assessment of which claims of US8156360 it potentially anticipates under 35 U.S.C. § 102. The analysis will focus on the independent claims (Claims 1, 8, 15, and 22) of US8156360.

The core innovative aspects of US8156360's independent claims revolve around a wireless device in a reduced power mode that monitors a plurality of wireless channels for a wake-up packet during a monitor timeframe, and either transitions to a full power mode upon receipt or ceases monitoring if no packet is received after the timeframe.

Here is an analysis of the cited prior art:

Prior Art Analysis for US8156360

1. US5802305A

   • Full Citation: US5802305A, Microsoft Corporation, "System for remotely waking a sleeping computer in power down state by comparing incoming packet to the list of packets storing on network interface card", Publication date: 1998-09-01.
   • Publication/Filing Date: 1996-05-17 (Priority date) / 1998-09-01 (Publication date).
   • Brief Description: This patent describes a system for remotely waking a "sleeping" computer in a power-down state. It involves a network interface card (NIC) that, while the computer is in a low-power state, monitors incoming packets and compares them against a stored list of packets to identify a wake-up signal. If a match is found, the computer is woken up. This patent primarily addresses wired Wake-on-LAN (WoL) scenarios.
   • Potential Anticipation (35 U.S.C. § 102): This patent anticipates the general concept of remotely waking a computer from a low-power state using a NIC and a wake-up packet. However, it specifically describes a wired LAN context ("comparing incoming packet to the list of packets storing on network interface card"). The independent claims of US8156360 are specific to wireless devices and plurality of wireless channels. Therefore, it does not directly anticipate Claims 1, 8, 15, or 22 of US8156360 due to the lack of wireless channel monitoring.

2. US5898904A

   • Full Citation: US5898904A, General Wireless Communications, Inc., "Two-way wireless data network having a transmitter having a range greater than portions of the service areas", Publication date: 1999-04-27.
   • Publication/Filing Date: 1995-10-13 (Priority date) / 1999-04-27 (Publication date).
   • Brief Description: This patent describes a two-way wireless data network with a transmitter covering a wide area, potentially addressing power management within such a network. However, its primary focus, based on the title, appears to be network architecture and range, not specific wake-up mechanisms from a sleep mode for wireless clients.
   • Potential Anticipation (35 U.S.C. § 102): The description is too general to directly anticipate the specific wake-up mechanisms of Claims 1, 8, 15, or 22 of US8156360. There is no explicit mention of monitoring a plurality of wireless channels for a wake-up packet during a monitor timeframe in a low-power state.

3. US5938771A

   • Full Citation: US5938771A, Advanced Micro Devices, Inc., "Apparatus and method in a network interface for enabling power up of a host computer using magic packet and on-now power up management schemes", Publication date: 1999-08-17.
   • Publication/Filing Date: 1997-10-30 (Priority date) / 1999-08-17 (Publication date).
   • Brief Description: This patent describes an apparatus and method for enabling a host computer to power up using "Magic Packet" technology and "on-now" power management. It relates to the core Wake-on-LAN (WoL) functionality, likely in a wired context, given the mention of "Magic Packet technology" which originated with Ethernet.
   • Potential Anticipation (35 U.S.C. § 102): Similar to US5802305A, this patent discloses a wake-on-LAN mechanism using "Magic Packets" for power management. US8156360 explicitly mentions "MAGIC PACKET technology" as prior art (referencing US6049885A) but applies it to wireless LANs. This patent, by itself, does not disclose the "plurality of wireless channels" monitoring aspect crucial to the independent claims of US8156360.

4. US6049885A

   • Full Citation: US6049885A, Advanced Micro Devices, Inc., "Method and apparatus for allowing a remote node to awaken a sleeping node of a network", Publication date: 2000-04-11.
   • Publication/Filing Date: 1994-10-20 (Priority date) / 2000-04-11 (Publication date).
   • Brief Description: This patent describes the "MAGIC PACKET technology" for waking a PC over a LAN. It details a LAN controller monitoring incoming frames for a specific data sequence (the Magic Packet, consisting of 16 duplications of the IP address). This reference is explicitly cited in the background of US8156360 as the foundation of wired Wake-on-LAN.
   • Potential Anticipation (35 U.S.C. § 102): This patent is core wired Wake-on-LAN prior art. It discloses a device entering a power-saving mode, a controller monitoring for a specific wake-up sequence (Magic Packet), and restoring full power upon detection. However, it does not teach monitoring a plurality of wireless channels in a wireless LAN environment, nor the specific timing aspects of "monitor timeframe" and "ceasing to monitor" particular to the wireless context. Therefore, it does not anticipate Claims 1, 8, 15, or 22 of US8156360, which extend this concept to wireless devices with channel scanning.

5. US6052779A

   • Full Citation: US6052779A, International Business Machines Corporation, "Automatic wake-up of systems in a data processing network", Publication date: 2000-04-18.
   • Publication/Filing Date: 1997-08-08 (Priority date) / 2000-04-18 (Publication date).
   • Brief Description: This patent describes an automatic wake-up system for networked computers. While it deals with remote wake-up, the title doesn't suggest it is focused on wireless networks or the specific multi-channel scanning with timeframes as claimed in US8156360.
   • Potential Anticipation (35 U.S.C. § 102): Without more specific details about its implementation (wired vs. wireless, channel monitoring specifics), it cannot be definitively stated to anticipate the wireless channel monitoring and timed cessation of monitoring found in Claims 1, 8, 15, or 22 of US8156360.

6. US6094443A

   • Full Citation: US6094443A, Advanced Micro Devices, Inc., "Apparatus and method for detecting a prescribed pattern in a data stream by selectively skipping groups of nonrelevant data bytes", Publication date: 2000-07-25.
   • Publication/Filing Date: 1997-10-30 (Priority date) / 2000-07-25 (Publication date).
   • Brief Description: This patent, also from AMD, likely relates to an improvement for Magic Packet detection by optimizing the scanning process for a specific data pattern within a data stream. This is a technical detail related to pattern matching efficiency.
   • Potential Anticipation (35 U.S.C. § 102): This patent improves the detection of a wake-up pattern, which is relevant to a component of US8156360 (the comparator 367 and signal processor 366). However, it does not describe the broader context of wireless channels, monitoring timeframes, and ceasing to monitor as outlined in Claims 1, 8, 15, or 22. It is a refinement for a wired-LAN-centric wake-up signal detection.

7. US6101608A

   • Full Citation: US6101608A, Compaq Computer Corporation, "Method and apparatus for secure remote wake-up of a computer over a network", Publication date: 2000-08-08.
   • Publication/Filing Date: 1997-02-20 (Priority date) / 2000-08-08 (Publication date).
   • Brief Description: This patent focuses on providing secure remote wake-up of a computer over a network. While enhancing security, it still appears to operate within the established paradigm of remote wake-up, likely for wired networks.
   • Potential Anticipation (35 U.S.C. § 102): The addition of security features to a remote wake-up system does not inherently disclose the wireless, multi-channel monitoring, and timed cessation features of US8156360's independent claims.

8. US6134665A

   • Full Citation: US6134665A, Digital Equipment Corporation, "Computer with remote wake up and transmission of a status packet when the computer fails a self test", Publication date: 2000-10-17.
   • Publication/Filing Date: 1998-01-20 (Priority date) / 2000-10-17 (Publication date).
   • Brief Description: This patent describes a computer with remote wake-up capabilities and the additional feature of transmitting a status packet if a self-test fails upon waking. The remote wake-up itself is likely based on wired LAN technologies.
   • Potential Anticipation (35 U.S.C. § 102): The primary focus is on fault reporting after wake-up, not the fundamental mechanism for wireless wake-up or the specific channel monitoring and timing aspects claimed in US8156360. The confirmation packet in Claim 4 of US8156360 is broader ("when the wireless device has completed the transition"), not tied to a self-test failure.

9. US6272628B1

   • Full Citation: US6272628B1, International Business Machines Corporation, "Boot code verification and recovery", Publication date: 2001-08-07.
   • Publication/Filing Date: 1998-12-14 (Priority date) / 2001-08-07 (Publication date).
   • Brief Description: This patent focuses on boot code verification and recovery, which is a system-level function related to system integrity rather than remote wake-up mechanisms.
   • Potential Anticipation (35 U.S.C. § 102): This patent is unrelated to the subject matter of waking wireless LAN devices and does not anticipate any claims of US8156360.

10. US6304899B1

    • Publication/Filing Date: 1998-10-08 (Priority date) / 2001-10-16 (Publication date).
    • Brief Description: This patent describes a system and method for powering on a remote client computer system using a wireless signal. This is highly relevant as it explicitly mentions "wireless signal" for wake-up. It might involve a simple wireless trigger rather than continuous multi-channel scanning.
    • Potential Anticipation (35 U.S.C. § 102): This patent is very relevant. It discloses powering on a device using a wireless signal. The key distinction for anticipation of US8156360's independent claims (1, 8, 15, 22) would be whether it discloses monitoring a plurality of wireless channels for a wake-up packet during a monitor timeframe and ceasing to monitor when no wake-up packet has been received after the monitor timeframe has elapsed. Without the full text, it's difficult to confirm these specific timing and multi-channel aspects. If it describes a simpler wireless wake-up, it might anticipate the broad idea of wireless wake-up but not the specific power-saving channel scanning method of US8156360.

11. US6311276B1

    • Full Citation: US6311276B1, 3Com Corporation, "Secure system for remote management and wake-up commands", Publication date: 2001-10-30.

This is highly relevant with a priority date before US8156360's filing date (2008-07-07), although after its priority date (2004-11-24). Given that it explicitly mentions "wake on wireless networks," it is a very strong candidate for prior art.
    • Potential Anticipation (35 U.S.C. § 102): The priority date (2003-12-03) is prior to US8156360's priority date (2004-11-24). This patent application is extremely relevant. It directly addresses "wake on wireless networks." The key for anticipation of US8156360's independent claims (1, 8, 15, 22) would be whether it discloses the specific elements of monitoring a plurality of wireless channels for a wake-up packet during a monitor timeframe, transitioning upon receipt before the timeframe, and ceasing to monitor if not received after the timeframe. If these elements are present, it would anticipate Claims 1, 8, 15, and 22.

    • Publication/Filing Date: 2004-03-26 (Priority date) / 2005-09-29 (Publication date).
    • Brief Description: This patent application describes a MAC-controlled sleep/wake-up mode with staged wake-up for power management. The priority date (2004-03-26) is prior to US8156360's priority date (2004-11-24).
    • Potential Anticipation (35 U.S.C. § 102): This patent application is highly relevant. It explicitly covers "sleep mode/wake-up mode with staged wake-up for power management" and being "MAC controlled." The crucial question for anticipation of US8156360's independent claims (1, 8, 15, 22) is whether it details the monitoring a plurality of wireless channels for a wake-up packet during a monitor timeframe, transitioning upon receipt before the timeframe, and ceasing to monitor if not received after the timeframe. If these elements are present, it would anticipate Claims 1, 8, 15, and 22. Given the focus on "MAC controlled" power management, it is very plausible it would involve network interface monitoring for wake-up.

    • Brief Description: This patent describes a method for configuring a computer system for Wake-on-LAN. This relates to the setup and readiness of a system for remote wake-up.
    • Potential Anticipation (35 U.S.C. § 102): The focus on configuration for Wake-on-LAN does not disclose the specific wireless multi-channel monitoring and timed cessation as claimed in US8156360.

35. US20060041615A1

    • Full Citation: US20060041615A1, Remy Blank, "Wireless delegate information and communication device, method and system", Publication date: 2006-02-23.
    • Publication/Filing Date: 2004-08-05 (Priority date) / 2006-02-23 (Publication date).
    • Brief Description: This patent application describes a wireless delegate information and communication device, method, and system. Its priority date (2004-08-05) is prior to US8156360's priority date (2004-11-24).
    • Potential Anticipation (35 U.S.C. § 102): This patent application mentions "wireless" communication and device. Without further details on its power management or wake-up mechanisms, it's hard to definitively state anticipation of the specific elements of US8156360's independent claims (1, 8, 15, 22) related to multi-channel scanning with timeframes and cessation.
