What this shows Hunan's Innovation Score is 64.3/100 (top 2% 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 Hunan?

Each dot is one of Hunan’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). Hunan’s own 9.2 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hunan's grants concentrate

Hunan Brunp Recycling Technology Co., Ltd. is a focused PatentsView assignee: 45 CPC subclasses with 77.9% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2024 (51 grants) versus a trough of 1 in 2017. By volume, Hunan sits between GAF Energy LLC and L3 Technologies, Inc..

Hunan's three-year grant acceleration

Hunan Brunp Recycling Technology Co., Ltd. shows 59 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.
