What this shows China's Innovation Score is 46.0/100 (top 22% 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.

Where China's grants concentrate

China Construction Industrial & Energy Engineering Group Co., Ltd is a focused PatentsView assignee: 15 CPC subclasses with 37.5% 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 (2 grants) versus a trough of 1 in 2022. By volume, China sits between Checkmarx Ltd. and China Resources Microelectronics (CHONGQING) Co., Ltd..

China's three-year grant acceleration

China Construction Industrial & Energy Engineering Group Co., Ltd shows 4 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.
