What this shows Yangtze's Innovation Score is 40.4/100 (top 36% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Yangtze?

Each dot is one of Yangtze’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Yangtze’s own 4.3 claims/patent is at or below the 7.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yangtze's grants concentrate

Yangtze Delta Region Institute (HUZHOU), University OF Electronic Science AND Technology OF China is a focused PatentsView assignee: 9 CPC subclasses with 71.4% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2024 (4 grants) versus a trough of 2 in 2023. By volume, Yangtze sits between Xtrava Inc. and Yixiang Blow Molding Furniture Co., Ltd..

Yangtze's three-year grant acceleration

Yangtze Delta Region Institute (HUZHOU), University OF Electronic Science AND Technology OF China shows 6 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
