Prior art

To identify the most relevant prior art for US patent 11009162, I will examine the cited patents listed within its specification. The claims of US11009162 center on a hydraulic fracturing system featuring an electric pump, a flexible hose of a "first diameter," and a specialized fitting that connects this hose to the pump's inlet at a "second diameter," where the second diameter is notably larger than the first diameter. Claim 9 further specifies this fitting to include a union, a shank end, and a reducer with an increasing axial diameter, welded to the union and shank end.

Given that the provided patent text for US11009162 includes the titles of its cited prior art but not their full specifications or abstracts, my assessment of potential anticipation under 35 U.S.C. § 102 will be based primarily on these titles. I will focus on cited patents marked with an asterisk (*), as these often represent references deemed particularly relevant by the examiner.

Based on the titles, the most relevant prior art appears to be those that address fittings, couplings, or hose connections, which directly relate to the inventive fitting in US11009162.

Here are the most relevant prior art references identified from the US11009162 patent document:

Most Relevant Prior Art

1. US3055682A - Adjustment fitting for reinforced hose in which a seal is maintained during adjustment

   • Full Citation: US3055682A, "Adjustment fitting for reinforced hose in which a seal is maintained during adjustment," issued to Aeroquip Corp. [cite: US11009162B1 - Citations]
   • Publication/Filing Date: Priority date: 1955-10-11; Publication date: 1962-09-25. [cite: US11009162B1 - Citations]
   • Brief Description: This patent describes a fitting designed for reinforced hoses, specifically emphasizing the maintenance of a seal during adjustment. Its title suggests a focus on the mechanical aspects of securing a hose and ensuring fluid integrity.
   • Potential Anticipation (35 U.S.C. § 102): This reference potentially anticipates the general concept of a "fitting between the hose and the electric powered pump" as broadly recited in Claim 1 and "a fitting" in Claim 9. However, the title alone does not explicitly disclose the critical feature of US11009162, which is a fitting designed to connect a hose of a first diameter to a pump connection of a second, larger diameter, nor does it explicitly detail a "reducer" with an increasing axial diameter to achieve this transition, as specified in Claim 9. Without the full patent text of US3055682A, it is not possible to determine if this specific diameter transition is taught.

2. US8091928B2 - Coupling assembly for connection to a hose

   • Full Citation: US8091928B2, "Coupling assembly for connection to a hose," issued to Eaton Corporation. [cite: US11009162B1 - Citations]
   • Publication/Filing Date: Priority date: 2009-02-26; Publication date: 2012-01-10. [cite: US11009162B1 - Citations]
   • Brief Description: This patent describes a coupling assembly specifically designed for connecting to a hose. The title suggests a general focus on the hardware and mechanism for hose attachment.
   • Potential Anticipation (35 U.S.C. § 102): Similar to US3055682A, this patent potentially anticipates the broader elements of "a fitting" or "a coupling assembly for connection to a hose." However, the key distinguishing feature of US11009162's claims (Claim 1 and Claim 9) lies in the fitting's ability to transition from a smaller hose diameter (first diameter) to a larger pump connection diameter (second diameter) via a specifically structured reducer. The title of US8091928B2 does not indicate this specific diameter change or the presence of a reducer for such a purpose. Therefore, while it anticipates the general idea of a hose coupling, its ability to anticipate the specific inventive step of accommodating the differential diameters and the detailed structure of the reducer in Claim 9 is not evident from the provided information.
