Where Yichang's grants concentrate

Yichang Jingwei Textile Machinery Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under D01H (Spinning OR Twisting). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2019. By volume, Yichang sits between Yang JI Co., Ltd. and Yongkang Ailant Industry AND Trade Co., Ltd..

Yichang's three-year grant acceleration

Yichang Jingwei Textile Machinery Co., Ltd. shows 4 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.
