Prior art — US Patent 10224999

Here is an analysis of the most relevant prior art for US patent 10224999, based on the citations within the patent and information from Google Patents. It is important to note that a full anticipation analysis under 35 U.S.C. § 102 requires a detailed, claim-by-claim comparison and legal interpretation, which is beyond the scope of this response. The potential anticipations described below are conceptual observations based on the abstracts and descriptions of the cited prior art.

US Patent 10224999: Broadband Repeater with Security for Ultrawideband Technologies

Abstract Summary: The patent describes an ultrawideband (UWB) radio transceiver/repeater that offers a low-cost infrastructure solution. It integrates wireless and wired network devices, connects to a "plant" (backbone), and provides flexible repeater capabilities, network security, traffic monitoring, provisioning, and flow control. The repeater can be implemented in various forms (discrete, integrated, distributed, or embedded).

Key Novel Aspects (from patent description):

Ability to filter and process data, store, process, and forward received data.
Suppression or "killing" of undesired data (spam, interference, undesired users).
Prioritization of traffic access and flows based on application requirements.
Intelligence afforded by processing, storage, and antenna/RF control.
Fusing of wireless UWB and wired network components.
Network monitoring, "network learning," and spam filtering.
Adaptable, steerable, electronic phasing, or MIMO antennas.
Various form factors, including integration into AC outlets or other appliances.

U.S. Pat. No. 6,505,032 (McCorkle et al.)
- Full Citation: US6505032B1, "UWB impulse generator for a communication system," issued January 7, 2003, to Xtreme Spectrum, Inc., inventors John McCorkle et al.
- Publication/Filing Date: January 7, 2003 (Publication Date); August 16, 2001 (Filing Date).
- Brief Description: This patent describes an ultrawideband (UWB) impulse generator that produces very short duration electrical impulses, which are then radiated as UWB electromagnetic pulses. It focuses on the generation and control of UWB signals, including aspects like pulse duration, timing, and repetition rate, for use in communication systems. It is foundational to UWB technology.
- Potential Anticipation (35 U.S.C. § 102):
  - This patent broadly describes UWB technology and its application in communication systems. While it does not describe a repeater with security or traffic management features, it establishes the fundamental existence of UWB communication, which is the basis for US10224999.
  - It could potentially anticipate the concept of using UWB signals for communication mentioned in various claims, particularly the preamble of claims, e.g., "A method for operating an ultrawideband (UWB) repeater..." (Claim 1), or "An ultrawideband (UWB) repeater..." (Claim 3). It does not, however, describe the novel repeater functionality.
U.S. Patent Application Publication No. 2003/0096578 A1 (McCorkle et al.)
- Full Citation: US20030096578A1, "Coherent ultrawideband communication system," published May 22, 2003, to Xtreme Spectrum, Inc., inventors John McCorkle et al.
- Publication/Filing Date: May 22, 2003 (Publication Date); November 21, 2001 (Filing Date).
- Brief Description: This application describes a coherent ultrawideband (UWB) communication system. It details methods for improving receiver sensitivity and communication range by coherently combining received UWB pulses, thus enhancing the signal-to-noise ratio. It covers aspects of UWB transceivers, synchronization, and data transmission methods using UWB pulses.
- Potential Anticipation (35 U.S.C. § 102):
  - Similar to US6505032B1, this application provides further detail on UWB communication systems and transceivers, focusing on improving link quality. It helps establish the state of the art for UWB communication itself, including concepts of transmission and reception that are inherent in any UWB device, including a repeater.
  - It could potentially anticipate the foundational elements of UWB transceivers and communication links (e.g., the UWB chips 28 and 28' mentioned in FIG. 3 of US10224999), but not the specific repeater architecture, security, or traffic management functions of US10224999. It touches upon enhancing signal-to-noise ratio (SNR) for UWB devices (a need that repeaters address), which is broadly related to the problem US10224999 aims to solve.
U.S. Patent Application Publication No. 2002/0198977 A1 (Cho)
- Full Citation: US20020198977A1, "Seamless roaming communication method and apparatus for WLAN and mobile communication system," published December 26, 2002, to Dong-Ho Cho.
- Publication/Filing Date: December 26, 2002 (Publication Date); June 21, 2001 (Filing Date).
- Brief Description: This patent application describes a communication method and apparatus that enables seamless roaming between a Wireless Local Area Network (WLAN) and a mobile communication system (e.g., cellular network). It focuses on handoff procedures, maintaining connection, and providing communication services across different wireless network types. It addresses mobility and connectivity in heterogeneous wireless environments.
- Potential Anticipation (35 U.S.C. § 102):
  - While this patent application addresses seamless roaming and connectivity in wireless networks, it does so for WLAN and mobile communication systems, not specifically UWB, nor does it detail the specific repeater functionality with security, filtering, and traffic management for UWB as claimed in US10224999.
  - It does, however, broadly relate to the need for maintaining connectivity and performance in diverse wireless environments, which is a problem contextually addressed by US10224999's repeater function for UWB. The "roaming systems and protocols" are mentioned in the background of US10224999 as a reason for the emergence of proper processing, filtering, security, and bandwidth provisioning in future wireless networks. Thus, it sets a general precedent for systems dealing with network connectivity issues in varying wireless conditions.
  - It might broadly anticipate the general concept of facilitating network connectivity across different network segments or for mobile users, but not the specific technical implementation of a UWB repeater with intelligent data processing, filtering, and security features.
