US 11668420

Here's a concise summary of US Patent 11668420:

US Patent 11668420

• Title: System and method for integrated flow supply line
• Assignee: US Well Services LLC
• Inventors: Jared Oehring, Brandon Hinderliter, Lon Robinson, Alexander James Christinzio
• Filing Date: 2021-05-17
• Issue Date: 2023-06-06
• Abstract: A hydraulic fracturing system includes an electric-powered pump connected to a fluid source by a flexible hose. This hose has a first diameter, and a fitting connects it to the electric pump at a second, larger diameter. The system uses this configuration to supply a slurry for subterranean formation fracturing.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a hydraulic fracturing system that features an electric multi-plunger pump, a fluid source providing a slurry, and a specialized hose connecting them. The hose has two ends with a larger diameter (first and second diameters) and a main body section with a smaller third diameter. A pair of fittings forms these ends, each having a shank that receives the hose body and a union for connecting to the fluid source or the electric pump.
• Claim 11: Similar to Claim 1, this claim describes a hydraulic fracturing system with an electric multi-plunger pump, a fluid source, and a hose with larger diameter ends and a smaller diameter body. However, Claim 11 provides more specific details about the fittings. Each fitting includes a union with a diameter larger than the hose's end diameter, a shank end for receiving and securing a portion of the hose, and a welded reducer positioned between the union and the shank end. This reducer has an increasing diameter along its length and extends at least partially into the union.

CAFC 2026 Dockets:

Based on the provided patent text, there is no direct listing of US Patent 11668420 in the CAFC 2026 dockets. However, the patent family is noted to have ongoing litigation, which could potentially lead to CAFC involvement in the future. Specifically, the patent mentions:

• A PTAB case, IPR2025-01539, which was filed but "Not Instituted - Procedural".
• A US case filed in the Texas Eastern District Court, case number 2:25-cv-00522.
• First worldwide family litigation filed.

As of April 26, 2026, the provided information does not definitively indicate that US Patent 11668420 is currently active in the CAFC 2026 dockets, but rather points to related litigation in other venues that commenced in 2025.US Patent 11668420

• Title: System and method for integrated flow supply line

• Inventors: Jared Oehring, Brandon Hinderliter, Lon Robinson, Alexander James Christinzio
• Filing Date: 2021-05-17
• Issue Date: 2023-06-06
• Abstract: A hydraulic fracturing system for fracturing a subterranean formation includes an electric powered pump having an inlet and an outlet, the outlet coupled to a well associated with the subterranean formation and powered by at least one electric motor. The system also includes a fluid source, coupled to the inlet of the electric powered pump, the fluid source providing a slurry for injection into the subterranean formation. The system further includes a hose extending between the fluid source and the electric powered pump, the hose being flexible and having a first diameter. The system includes a fitting between the hose and the electric powered pump, the fitting having a first end for receiving the hose at the first diameter and a second end for coupling to the electric powered pump at a second diameter, the second diameter being larger than the first diameter.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a hydraulic fracturing system. It includes an electric-powered, multi-plunger pump that delivers fluid to a well. A fluid source provides a slurry to the pump's inlet. Connecting the fluid source and the pump is a flexible hose. This hose has a specific design: its ends (for coupling to the fluid source and the pump inlet) have a larger diameter (first and second diameters), while the main body of the hose between these ends has a smaller third diameter. A pair of fittings forms these specialized ends, with each fitting having a shank end to receive part of the hose body and a union to connect to either the fluid source or the pump.
• Claim 11: This claim also details a hydraulic fracturing system, similar to Claim 1, with an electric multi-plunger pump, a fluid source, and a hose with larger diameter ends and a smaller diameter body. However, Claim 11 provides more specific structural details for the pair of fittings. Each fitting comprises a union (at one end, with a union diameter larger than the first diameter of the hose end), a shank end (at the other end, configured to receive and be secured to a portion of the hose body, and including an opening for the hose), and a reducer positioned between the union and the shank end. This reducer is welded to both the union and the shank end, has an increasing diameter along its axial length, and extends at least partially into the union.

CAFC 2026 Dockets:

The provided patent text indicates that there is no direct listing of US Patent 11668420 within the CAFC 2026 dockets as of the current date. However, the patent family has ongoing litigation in other venues that commenced in 2025. This includes:

• A PTAB case, IPR2025-01539, which was filed but "Not Instituted - Procedural."
• A US case filed in the Texas Eastern District Court, case number 2:25-cv-00522.
• The first worldwide family litigation has also been filed.

While these cases are not directly listed as CAFC dockets for 2026, ongoing litigation at the PTAB or District Courts could potentially lead to appeals at the CAFC.
