What this shows Hubei's Innovation Score is 32.6/100 (42nd percentile 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 Hubei?

Each dot is one of Hubei’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). Hubei’s own 7.8 claims/patent is ABOVE the 5.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hubei's grants concentrate

Hubei Jinhanjiang Refined Cotton Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under D01G (Preliminary Treatment OF Fibres, e.g. FOR Spinning). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2016. By volume, Hubei sits between HS Products Engineering GmbH and Huizhou Victory Technology Ltd..

Hubei's three-year grant acceleration

Hubei Jinhanjiang Refined Cotton Co., Ltd. shows 3 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.
