Where China's grants concentrate

China Tobacco Hunan Industrial Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 87.3% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). Peak complete grant year is 2024 (18 grants) versus a trough of 1 in 2015. By volume, China sits between Brose Fahrzeugteile GmbH & Co. KG, Hallstadt and Cardinal IG Company.

China's three-year grant acceleration

China Tobacco Hunan Industrial Co., Ltd. shows 39 grants in 2022–2024 against only 9 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.
