The patent US11856414B1 has the following details:

• Title: Method and apparatus for processing bandwidth intensive data streams using virtual media access control and physical layers
• Assignee: Xifi Networks R and D Inc
• Inventor: Sai C. Manapragada
• Filing Date: 2023-08-10
• Issue Date (Publication Date): 2023-12-26

Abstract:
A wireless networking system is disclosed, comprising an application layer with applications having wireless bandwidth requirements. It uses first and second wireless transceiver resources, each linked to an actual MAC and PHY layer, with their own bandwidth availabilities. A processing layer evaluates these bandwidth requirements and availabilities. This processing layer includes a bandwidth allocator that assigns portions of the first and second actual bandwidths to virtual MAC and virtual PHY layers to satisfy the application's wireless bandwidth needs.

Plain-language overview of the Independent Claims:

• Independent Claim 1: This claim describes a method for improving the performance of a wireless networking device. It involves connecting an application interface (for a first application with a data stream and bandwidth requirement) to a processing interface. First and second actual MAC and PHY interfaces are connected to the processing interface, with associated wireless transceivers that operate in different frequency bands and are suitable for a wireless local area network. The processing interface forms virtual MAC and virtual PHY interfaces, where the virtual PHY interfaces feed bandwidth availability information back to the virtual MAC interface. The processing interface is configured to, transparently to layers above it, request or create associations between a recipient and the actual MAC/PHY interfaces, identify portions of available bandwidth from the transceivers, and evaluate them against the application's bandwidth requirement. If the requirement is at least partially met, the first data stream is prepared for simultaneous transmission from both transceivers using a specific subset of frequencies. A key aspect is that this utilization of bandwidth by the wireless networking device does not prevent other wireless networking devices from using the remaining bandwidth for data transmission concurrently.

Regarding CAFC 2026 dockets for patent 11856414, the search results do not explicitly show any CAFC dockets for this specific patent number in 2026. The search results include general information about CAFC case information and a case summary from September 4, 2025, about an unrelated patent (Lindis Biotech, GMBH) and inequitable conduct. It also provides information on the USPTO's patent litigation docket reports data, which was last updated through 2020 and March 2024 for certain datasets, but doesn't mention specific dockets for 11856414 in 2026. Therefore, I cannot confirm any ongoing CAFC litigation for US11856414B1 based on the provided search results.US Patent 11856414, titled "Method and apparatus for processing bandwidth intensive data streams using virtual media access control and physical layers," was issued to Xifi Networks R and D Inc. The inventor is Sai C. Manapragada. The patent has a filing date of August 10, 2023, and an issue date of December 26, 2023.

Abstract:
The patent discloses a wireless networking system that enhances performance for bandwidth-intensive data streams. It features an application layer with specific wireless bandwidth needs, which are met by leveraging multiple wireless transceiver resources connected to actual MAC and PHY layers. A processing layer assesses these bandwidth requirements and the available bandwidth from the transceivers. This processing layer includes a bandwidth allocator that assigns portions of the actual bandwidths to virtual MAC and virtual PHY layers to fulfill the application's demands.

Plain-language overview of Independent Claim 1:
Claim 1 describes a method for improving the performance of a wireless networking device. This method involves:

1. Connecting an application (which has a data stream and a specific wireless bandwidth requirement) through an application interface to a processing interface.
2. Connecting at least two sets of actual MAC and PHY interfaces to the processing interface, each with its own wireless transceiver. These transceivers are suitable for Wi-Fi networks, have available bandwidth, and operate in different frequency bands.
3. Within the processing interface, creating at least one virtual MAC interface and at least two virtual PHY interfaces. These virtual PHY interfaces provide real-time feedback about the transceivers' bandwidth availability to the virtual MAC interface.
4. The processing interface, operating transparently to higher network layers, then performs several actions:
   • It establishes a connection (association) between a recipient and the actual MAC and PHY interfaces of both transceivers.
   • It identifies and evaluates specific portions of the available bandwidth from both transceivers against the application's bandwidth requirement.
5. If the application's bandwidth requirement can be at least partially met by these identified bandwidth portions, the data stream is prepared for simultaneous transmission to the recipient using the specified frequencies from both transceivers.
6. Crucially, the patent emphasizes that this utilization of bandwidth by the networking device does not prevent other wireless devices from using the remaining available frequency ranges of the transceivers for their own data transmissions at the same time.

As of April 26, 2026, no specific CAFC 2026 dockets for patent 11856414 were found in the provided search results. The search results included general information about CAFC case information and USPTO litigation data, but did not indicate any active litigation for this patent in 2026.
