Prior art

The most relevant prior art for US Patent 9207748 can be identified by examining the "Cited By" and "Citations" sections of the patent itself. The patent document lists prior art patents and non-patent literature that were considered during its examination. Under 35 U.S.C. § 102, a claim is anticipated if every element of the claim is found in a single prior art reference.

Here's an analysis of some of the cited prior art from US9207748:

Patent Citations (Selected Examples from US9207748):

• US6049885A

  • Full Citation: US 6,049,885 A, "Method and apparatus for allowing a remote node to awaken a sleeping node of a network"
  • Publication Date: April 11, 2000 (Filed: October 20, 1994)
  • Brief Description: This patent describes the "MAGIC PACKET technology" for waking up a PC over a Local Area Network (LAN). Before entering a sleep mode, the LAN controller goes into a "MAGIC PACKET mode" where it monitors incoming frames for a specific data sequence (the MAGIC PACKET, consisting of 16 duplications of the IP address). If matched, full power is restored.
  • Potential Anticipation (35 U.S.C. § 102): This patent is highly relevant as it describes the fundamental concept of a "wake-up packet" (MAGIC PACKET) and a "power-save mode" where a network controller monitors for this packet to initiate a return to a "non-power-save mode". It directly addresses the core concepts of claims 1, 8, and 15, which involve entering a wake-up detection mode, receiving a wake-up packet, and performing a wake-up process. Specifically, the "MAGIC PACKET" comprising multiple consecutive iterations of the hardware address (IP address in 6,049,885) could anticipate elements of claim 6 and 13.

• US6304899B1

  • Full Citation: US 6,304,899 B1, "Data processing system and method for powering-on a remote client computer system utilizing a wireless signal"
  • Publication Date: October 16, 2001 (Filed: October 8, 1998)
  • Brief Description: This patent addresses powering on a remote client computer system using a wireless signal. It focuses on using a wireless signal to initiate the wake-up process.
  • Potential Anticipation (35 U.S.C. § 102): This patent specifically introduces the use of a wireless signal for remote wake-up, which is a key distinguishing feature of US9207748 over traditional wired Wake-on-LAN (WoL) like that in US6049885A. It could potentially anticipate the "wireless device" and "wirelessly returned to a full power mode" aspects of claims 1, 8, and 15, particularly concerning the wireless nature of the wake-up signal and device.

• US20030097398A1

  • Full Citation: US 2003/0097398 A1, "Wireless Connection For Portable Systems And Network adapters Using Wake-Up Requests"
  • Publication Date: May 22, 2003 (Filed: January 23, 1999)
  • Brief Description: This publication discusses wireless connections for portable systems and network adapters utilizing wake-up requests.
  • Potential Anticipation (35 U.S.C. § 102): Similar to US6304899B1, this reference highlights wireless wake-up for portable devices, strengthening the prior art landscape for the wireless aspects of US9207748. It could anticipate the concepts of a wireless device being woken from a power-save mode via a wake-up request over a wireless connection.

• US7398408B2

  • Full Citation: US 7,398,408 B2, "Systems and methods for waking up wireless LAN devices"
  • Publication Date: July 8, 2008 (Filed: November 24, 2004)
  • Brief Description: This patent, notably sharing the same priority date and original assignee (Intellectual Ventures I LLC) as US9207748, covers systems and methods for waking up wireless LAN devices. It describes a method for putting a wireless device into a reduced power mode and returning it to a full power mode using signals transmitted over a wireless LAN, including scanning multiple wireless data channels for a "MAGIC PACKET".
  • Potential Anticipation (35 U.S.C. § 102): This patent is a direct antecedent (a parent application) to US9207748 (via a chain of continuations and divisions). As such, it is highly likely to anticipate the fundamental aspects of claims 1, 8, and 15, particularly the method steps of scanning a plurality of wireless channels (claim 4, 11, 17) and the overall system and computer aspects for waking a wireless device from a power-save mode using a wake-up packet over a wireless LAN. It would also likely anticipate elements related to the "MAGIC PACKET" and its structure (claims 6, 13, 19). Any differences would likely lie in specific implementations or further refinements claimed in US9207748.

The provided patent text for US9207748 explicitly mentions the "MAGIC PACKET technology" and refers to U.S. Pat. No. 6,049,885 for a full description. This indicates that 6,049,885 is foundational prior art for the concept of using a specific data sequence to wake a sleeping node. US9207748 then extends this concept to wireless environments. The family relationship with US7398408B2 also makes it a primary piece of prior art.

To perform a complete anticipation analysis under 35 U.S.C. § 102, a detailed comparison of each element of claims 1-20 of US9207748 against the disclosures of these and other cited prior art references would be necessary. This analysis would examine whether each and every limitation of a claim is explicitly or inherently present in a single prior art reference.
