US 11211801

Here's a concise summary of US Patent 11211801:

US Patent: 11211801

• Title: Integrated mobile power unit for hydraulic fracturing
• Assignee: U.S. Well Services LLC
• Inventors: Brandon N. Hinderliter, Jared Oehring
• Filing Date: 2019-06-17
• Issue Date: 2021-12-28
• Abstract: A hydraulic fracturing system is described, featuring a single mobile platform with at least one mobile power unit (MPU) and at least one first switch gear. This switch gear is designed to manage electrical power from the MPU. The MPU generates voltage that matches the requirements of an electrical bus connected to the first switch gear, ensuring a combined electrical current is supplied to the hydraulic fracturing system's components. The system may also incorporate electrical fracturing equipment with a second switch gear to support the first switch gear in power handling. Automated control software, potentially housed in a datavan, can manage load shedding, load sharing, and power distribution for the electrical fracturing equipment.

Plain-Language Overview of Independent Claims:

The patent includes two independent claims: Claim 1 and Claim 18.

• Claim 1: A system comprising:
  This claim describes a system for hydraulic fracturing that includes a "first mobile unit" (e.g., a trailer or skid) which contains both "at least one first generator" and "at least one switch gear." The switch gear is also connected to "at least one transformer," an "interconnect," and a "bus bar." The first mobile unit is designed to use the power generated by its generator, distributed through the electrical buses of the switch gear, and via the transformer, interconnect, and bus bar, to supply power to loads located on "one or more external mobile units."

• Claim 18: A method comprising:
  This claim outlines a method for operating a hydraulic fracturing system. It involves "providing a first mobile unit" that houses "at least one first generator" and "at least one switch gear" (similar to the system in Claim 1). This switch gear is associated with "at least one transformer," an "interconnect," and a "bus bar." The method then involves "generating power" from the generator. Finally, it entails "providing the generated power" through the electrical buses of the switch gear, using the transformer, interconnect, and bus bar, to "at least one load in one or more external mobile units."

CAFC 2026 Dockets:

A search of CAFC 2026 dockets did not explicitly return any litigation or case filings specifically mentioning US patent 11211801 as of April 26, 2026, within the provided search results. While the Google Patents page indicates "Family has litigation," the specific court and year for that litigation are not detailed in the snippets to confirm activity at the CAFC in 2026.
