To identify the most relevant prior art for US patent 11964175, I will examine each patent cited by the examiner. For each cited patent, I will provide its full citation, publication/filing date, a brief description, and an assessment of which claims of US11964175 it potentially anticipates under 35 U.S.C. § 102.

The claims of US11964175 generally describe a bridge rope assembly for a harness, featuring a main body with an eye loop formed by a splice, where a first portion of the rope is fully buried within a second portion, resulting in the first and second ends being adjacent. A key aspect is the use of Ultra-High Molecular Weight Polyethylene (UHMWPE) for the rope material. The assembly also includes a friction hitch with a closed loop, also preferably made of UHMWPE, where its ends are buried a significant percentage of the loop's circumference.

Here is an analysis of the cited prior art:

Summary of Anticipation:
Based on the descriptions, none of the cited prior art documents appear to fully anticipate all elements of Claim 1 of US11964175. While some references discuss harnesses, ropes, splices, or friction hitches in a general sense, they do not disclose the specific combination of features central to US11964175, particularly:

  • The main body rope having a first portion extending through a second portion such that the first end is positioned within the second portion adjacent to the second end (distance between ends less than 2.0 inches).
  • The use of UHMWPE for the main body and/or the friction hitch (Claims 10, 11).
  • The specific structure of the closed loop friction hitch, where its ends are each buried a distance of at least 40% (and less than 50%) of the total circumference (as further detailed in the specification, which supports claims such as 6, 7, 8, 9, 13).

Therefore, based on the provided abstracts, the novelty of US11964175 appears to reside in the specific and detailed structural configuration of the splices (main body and friction hitch) leading to fully buried and closely positioned rope ends, combined with the application of UHMWPE material to achieve a high-strength, friction-resistant, and drop-test-passing assembly.
