Abstract:
The patent describes a wireless networking system featuring an application layer with one or more applications that have a wireless bandwidth requirement. It utilizes first and second wireless transceiver resources, each linked to an actual MAC and PHY layer, and possessing distinct bandwidth availabilities. A processing layer assesses these bandwidth requirements and availabilities. This processing layer includes a bandwidth allocator that assigns portions of these actual bandwidths to virtual MAC and virtual PHY layers to fulfill the application layer's wireless bandwidth needs.

Plain-Language Overview of Independent Claim 1:
Claim 1 describes a wireless networking device designed to handle demanding data streams. It features:

• An interface for applications (e.g., streaming video) that have specific wireless bandwidth needs.
• Two sets of standard (actual) MAC and PHY interfaces, each connected to a wireless transceiver capable of Wi-Fi communication and operating in different frequency bands. These transceivers have their own bandwidth capacities.
• A "processing interface" that acts as an intelligent intermediary. This processing interface contains a "virtual MAC interface" and a "resource monitoring interface." The resource monitoring interface constantly checks the available bandwidth of the wireless transceivers and feeds this information back to the virtual MAC interface.
• When the device is in use, the processing interface transparently (without higher layers of the network needing to know the specifics) performs several key actions:
  • It creates connections between a recipient (e.g., a user's device) and both actual MAC and PHY interfaces.
  • It identifies specific portions of the first wireless transceiver's total bandwidth, each with its own set of resources.
  • It evaluates the performance characteristics (e.g., signal quality, latency) of these identified bandwidth portions.
  • If one portion of the first transceiver's bandwidth offers better performance, the device uses only that first wireless transceiver to send the application's data stream to the recipient. This is done using only the frequencies corresponding to the available resources of the better-performing portion, and critically, without disconnecting the recipient from either of the actual MAC/PHY interfaces.
• A crucial aspect is that while the device is using these specific bandwidth portions, it does not prevent any other wireless networking device from using the remaining available frequencies of that same first wireless transceiver for other data at the same time.

CAFC 2026 Dockets:
A search of CAFC 2026 dockets did not return any specific cases directly involving US patent 12250564. However, the patent information itself indicates ongoing litigation, with a PTAB case (PGR2025-00069) filed and instituted, and a US case filed in the Texas Eastern District Court (2:24-cv-01057).
