Where Crrc's grants concentrate

Crrc Qiqihar Rolling Stock Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 36.4% of grants classified under B61D (Body Details OR Kinds OF Railway Vehicles). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2017. By volume, Crrc sits between Cria Inc. and CTC Analytics AG.

Crrc's three-year grant acceleration

Crrc Qiqihar Rolling Stock Co., Ltd. shows 2 grants in 2022–2024 against only 5 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.
