Here's a concise summary of US patent 12167415:

US Patent Number: 12167415
Title: Wireless communication method and wireless communication terminal, which use discontinuous channel
Assignee: Wilus Institute of Standards and Technology Inc.

Abstract: The present invention relates to a wireless communication method and a wireless communication terminal that utilize non-contiguous channels. More specifically, it pertains to a wireless communication method and terminal designed for efficiently signaling non-contiguous channel allocation information.

Plain-Language Overview of Independent Claims:

• Claim 1 (Wireless communication method for a terminal - receiving): This claim describes a method for a wireless communication terminal (like a smartphone or laptop) to receive data. The method involves the terminal's processor receiving a wireless packet, identifying information within that packet about how non-contiguous (disconnected) channels are allocated, and then using that allocation information to decode the received packet.
• Claim 8 (Wireless communication terminal - receiving): This claim describes a wireless communication terminal itself. It includes a processor and a communication unit. The processor is set up to perform the same actions as in Claim 1: receive a wireless packet, get the non-contiguous channel allocation information from it, and then decode the packet using that information.
• Claim 15 (Wireless communication method for a base terminal - transmitting): This claim details a method for a base wireless communication terminal (like an access point or base station) to transmit data. The method involves the base terminal's processor performing a Clear Channel Assessment (CCA) across multiple channels to prepare for a wideband transmission. It then transmits a packet using any channels found to be idle. Critically, if the packet is transmitted over non-contiguous channels, the base terminal signals this non-contiguous channel allocation information within a non-legacy preamble of the packet.
• Claim 20 (Base wireless communication terminal - transmitting): This claim describes a base wireless communication terminal itself. It includes a processor and a communication unit. The processor is configured to perform the actions outlined in Claim 15: perform CCA for wideband transmission, transmit a packet through idle channels, and signal non-contiguous channel allocation information in the non-legacy preamble when non-contiguous channels are used for transmission.

Litigation Status:
The patent family is noted to have litigation. However, a search of CAFC 2026 dockets did not directly yield specific litigation records pertaining to US patent 12167415. It is possible that the litigation is ongoing in a different court, not yet reached the CAFC, or is associated with other members of the patent family.
