Where China's grants concentrate

China Merchants Heavy Industry (Jiangsu) Co., Ltd is a focused PatentsView assignee: 12 CPC subclasses with 80% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). By volume, China sits between Chiayo Electronics Co., Ltd. and Ching Shenger Co., Ltd..

China's three-year grant acceleration

China Merchants Heavy Industry (Jiangsu) Co., Ltd shows 1 grants in 2022–2024 against only 2 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.
