US 12190198

The search for "CAFC 2026 dockets US12190198" did not yield any direct results indicating a case specifically involving patent US12190198 in the CAFC dockets for 2026. The search results returned general CAFC scheduled cases for May 2026 and some opinions from 2025 and 2026 related to trade and bid protests, but none are explicitly linked to US12190198.

The patent text itself, under "Family has litigation," mentions:

• "US case filed in Texas Eastern District Court"
• "PTAB case PGR2025-00067 filed (Pending - Instituted)"

This indicates ongoing litigation, but not specifically in the CAFC in 2026. Given the instructions to prioritize search results, and the absence of specific CAFC dockets for US12190198 in the search, I will state that there's no authoritative information from the search results regarding CAFC 2026 dockets for this patent.

Now, I will compile the summary of US12190198 using the information extracted from the provided patent text.

Uncertainty Note: The search for "CAFC 2026 dockets US12190198" did not return any specific cases related to this patent in the CAFC dockets for 2026. The provided patent text mentions litigation in the Texas Eastern District Court and a PTAB case (PGR2025-00067), but does not specify any CAFC cases for 2026.The US patent 12190198 (US12190198B1) is titled "Method and apparatus for processing bandwidth intensive data streams using virtual media access control and physical layers".

Abstract:
A wireless networking system is disclosed that includes an application layer with one or more applications having a wireless bandwidth requirement. The system utilizes first and second wireless transceiver resources, each associated with an actual MAC layer and PHY layer, and possessing distinct bandwidth availabilities up to their respective actual bandwidths. A processing layer evaluates the wireless bandwidth requirement and the bandwidth availabilities of these resources. This processing layer incorporates a bandwidth allocator designed to assign portions of the first and second actual bandwidths to virtual MAC and virtual PHY layers, thereby satisfying the application layer's wireless bandwidth requirement.

Plain-Language Overview of Independent Claim 1:
Claim 1 describes a method for improving the operation of circuitry in a wireless networking device. This method involves:

1. Application Interaction: A processing interface is provided that interacts with an application generating a data stream, which has a specific wireless bandwidth requirement.
2. Hardware Connection: First and second actual Media Access Control (MAC) interfaces are connected to this processing interface. Subsequently, first and second actual Physical (PHY) interfaces are connected to their respective MAC interfaces.
3. Transceiver Association: First and second wireless transceivers are associated with their respective actual PHY interfaces. These transceivers are designed for wireless local area networks, have their own bandwidth capacities, and importantly, are adapted to emit radio waves in different frequency bands.
4. Processing Interface Components: The processing interface itself includes:
   • At least one virtual MAC interface.
   • At least one resource monitoring interface. This monitoring interface, during the device's operation, continuously feeds information about the available bandwidths of the first and second transceivers to the virtual MAC interface.
5. Virtual MAC Allocation Decisions: The virtual MAC interface, once the circuitry is connected and during device use, operates in a way that is invisible to any higher-level software layers. It performs two key functions:
   • It requests or creates two associations for a recipient: one with the first actual MAC and PHY interfaces, and another with the second actual MAC and PHY interfaces.
   • It uses the real-time bandwidth availability information from the resource monitoring interface to make decisions on how to allocate portions of the first and second available bandwidths. This allocation is done to at least partially fulfill the bandwidth needs of the application's data stream.

Uncertainty Regarding CAFC 2026 Dockets:
Based on the conducted search, there is no authoritative information from the CAFC 2026 dockets directly referencing US patent 12190198. However, the patent document itself indicates other ongoing litigation, specifically a "US case filed in Texas Eastern District Court" and a "PTAB case PGR2025-00067 filed (Pending - Instituted)" related to this patent.
