Where Chongqing's grants concentrate

Chongqing Zongshen General Power Machine Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 60% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). By volume, Chongqing sits between Chongqing Fengrui Plastic Co., Ltd. and Chromatic 3D Materials, Inc..

Chongqing's three-year grant acceleration

Chongqing Zongshen General Power Machine Co., Ltd. shows 2 grants in 2022–2024 against only 1 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.
