5. US9371728B2

Full Citation: US9371728B2, "Mobile electric power generation and distribution system and method", filed June 25, 2014, issued June 21, 2016.
Publication/Filing Date: Filing: 2014-06-25; Publication: 2016-06-21.
Brief Description: This patent describes a mobile electric power generation and distribution system. It includes a mobile power unit (MPU) with a generator and a control trailer with switch gear. The system can provide power to various loads, potentially for oilfield operations. While it mentions mobile units and power distribution, the emphasis might not be on the integration of the generator and primary switch gear on a singular mobile platform in the same way as US11211801. However, it does address the concept of mobile power generation and distribution for industrial loads.
Potential Anticipation (35 U.S.C. § 102): US9371728B2 describes mobile power generation and distribution, but its abstract does not explicitly state the key inventive step of US11211801, which is the integration of the generator and at least one switch gear on a singular mobile platform. It mentions an MPU with a generator and a separate "control trailer with switch gear." If the control trailer is a separate mobile unit from the MPU housing the generator, then it would not anticipate the "singular and integrated mobile unit" aspect. However, it provides context for mobile power systems. Without the full text, it's difficult to definitively say, but based on the abstract, it does not clearly anticipate Claim 1 or Claim 18 regarding the singular integrated mobile unit.

It includes a prime mover, a generator, and control systems on a mobile platform for delivering electrical power to fracturing equipment. It discusses aspects of power distribution and load management in a mobile fracturing environment.
Potential Anticipation (35 U.S.C. § 102): Like the preceding "Mobile power unit" patents, this reference broadly covers mobile power for fracturing. However, its abstract does not specify the integration of the switch gear directly with the generator on the same singular mobile unit that then powers external mobile units. The focus appears to be on the mobile power unit and its control systems. Therefore, based on the abstract, it does not clearly anticipate Claim 1 or Claim 18.

9. US8904791B2

Full Citation: US8904791B2, "Mobile power unit and method for powering fluid pumping systems for hydraulic fracturing", filed May 13, 2013, issued December 9, 2014.

The abstract does not explicitly disclose the integration of the switch gear alongside the generator on a single mobile unit for distributing power to external mobile units, which is a key distinguishing feature of US11211801. Therefore, based on the abstract, it does not clearly anticipate Claim 1 or Claim 18.

10. US20180017006A1

Full Citation: US20180017006A1, "Integrated mobile power unit for hydraulic fracturing", filed July 10, 2017, published January 18, 2018.
Publication/Filing Date: Filing: 2017-07-10; Publication: 2018-01-18.
Brief Description: This published application describes a hydraulic fracturing system with a singular mobile platform housing at least one mobile power unit (MPU) and at least one first switch gear. The MPU generates power that matches the requirements of an electrical bus of the first switch gear, providing electrical current to the components of the hydraulic fracturing system. It also includes electrical fracturing equipment with a second switch gear and automated control software for managing power. This pre-dates the filing of US11211801 and has a highly similar description.
Potential Anticipation (35 U.S.C. § 102): Given the identical title and a highly similar abstract to US11211801, this published application likely discloses the same integrated system of a generator and switch gear on a singular mobile platform, supplying power to external loads in a hydraulic fracturing context. This directly covers the core elements of Claim 1 and Claim 18 of US11211801. Therefore, it potentially anticipates Claim 1 and Claim 18.

11. US20160290124A1

Full Citation: US20160290124A1, "Mobile electric power generation and distribution system and method", filed June 3, 2016, published October 6, 2016.
Publication/Filing Date: Filing: 2016-06-03; Publication: 2016-10-06.
Brief Description: This application describes a mobile electric power generation and distribution system for oilfield operations. It includes multiple mobile power units (MPUs) with generators and a separate electronic equipment room (EER) or control trailer with switch gear for power distribution and load management to various loads. The system enables load sharing among multiple MPUs.
Potential Anticipation (35 U.S.C. § 102): This application explicitly mentions "multiple mobile power units (MPUs) with generators and a separate electronic equipment room (EER) or control trailer with switch gear." The "separate" nature of the EER/control trailer (which houses the switch gear) from the MPU (which houses the generator) distinguishes it from the core "singular and integrated mobile unit" feature of US11211801's claims. While it provides mobile power generation and distribution for external loads, the critical integration aspect on a single mobile unit is absent. Therefore, it does not clearly anticipate Claim 1 or Claim 18.

12. US20130099516A1

Full Citation: US20130099516A1, "Mobile Power Unit and Method for Powering Fluid Pumping Systems for Hydraulic Fracturing", filed October 24, 2012, published April 25, 2013.

It includes a gas turbine and a generator mounted on a trailer or skid, providing electrical power to equipment at a wellsite. The system emphasizes mobility for remote oilfield applications.
Potential Anticipation (35 U.S.C. § 102): This patent describes a mobile power generation station with a gas turbine and generator on a trailer for oilfield operations. While it covers "mobile unit" and "generator," the abstract does not specify the integration of switch gear on the same singular mobile unit alongside the generator, nor does it explicitly detail the provision of power to "one or more external mobile units" in the context of load sharing and common buses as claimed in US11211801. Therefore, based on the abstract, it does not clearly anticipate Claim 1 or Claim 18.

18. WO2018027177A1

Full Citation: WO2018027177A1, "Modular power unit for fracturing and other field operations", filed August 5, 2016, published February 8, 2018.

The unit includes a power source (e.g., turbine or reciprocating engine) and a generator, with modular components allowing for flexibility in deployment and configuration. It may involve power distribution and control systems.
Potential Anticipation (35 U.S.C. § 102): This application discusses a "modular power unit" with a power source and generator for field operations. While "modular" implies flexibility, the abstract does not explicitly state the integration of switch gear directly with the generator on a singular mobile platform that then specifically provides power to external mobile units as defined in US11211801. The emphasis is on modularity, which is a broader concept. Therefore, based on the abstract, it does not clearly anticipate Claim 1 or Claim 18.

19. WO2015112165A1

Full Citation: WO2015112165A1, "Mobile electrical fracturing fleet", filed January 20, 2015, published July 30, 2015.

Potential Anticipation (35 U.S.C. § 102): This application describes a "mobile electrical fracturing fleet" with mobile power units and pumps, implying multiple mobile components. While it addresses power distribution in a fleet, its abstract does not clearly state the specific inventive step of US11211801: the integration of the generator and primary switch gear on a singular mobile platform that then powers external mobile units. It implies a distributed system rather than a singularly integrated one at the MPU level. Therefore, based on the abstract, it does not clearly anticipate Claim 1 or Claim 18.

20. EP2949826A1

Full Citation: EP2949826A1, "Mobile electric fracturing fleet", filed January 20, 2014, published December 2, 2015.

Potential Anticipation (35 U.S.C. § 102): This application, similar to WO2015112165A1, describes a "mobile electric fracturing fleet." Its abstract broadly covers mobile power and fracturing pumps but does not explicitly detail the integration of switch gear with a generator on a singular mobile unit that then provides power to external mobile units as defined in US11211801's claims. Therefore, based on the abstract, it does not clearly anticipate Claim 1 or Claim 18.

Most Relevant Prior Art Summary:

Based on the abstracts, the most relevant prior art references that potentially anticipate Claims 1 and 18 of US11211801 are those with highly similar titles and descriptions, strongly suggesting they cover the core inventive concept of integrating the generator and at least one switch gear on a singular mobile platform to power external mobile units for hydraulic fracturing. These include:

US10443477B2 [cite: The patent text itself references this patent number in a way that suggests it's a closely related or earlier version of the same technology/inventors, rather than a distinct prior art.

US20180017006A1

These references explicitly describe the integration of the MPU (generator) and switch gear on a single mobile platform, which is a distinguishing feature of US11211801's independent claims. The other listed prior art generally describes mobile power for fracturing but lacks the specific emphasis on this integrated configuration within a single mobile unit for the primary power generation and switching functions.
