Where Zhongce's grants concentrate
Zhongce Rubber Group Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 14.3% of grants classified under B60C (Vehicle TYRES; Tyre INFLATION; Tyre CHANGING; Connecting Valves TO Inflatable Elastic Bodies IN GENERAL; Devices OR Arrangements Related TO Tyres).

Zhongce's three-year grant acceleration
Zhongce Rubber Group Co., Ltd. shows 1 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.
