What this shows Yichang's Innovation Score is 36.0/100 (top 48% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Yichang?

Each dot is one of Yichang’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Yichang’s own 9.8 claims/patent is ABOVE the 8.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
