What this shows Hefei's Innovation Score is 41.2/100 (top 34% 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.

Where Hefei's grants concentrate

Hefei JEE Power Systems Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 85.7% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Hefei sits between HBL Corporation and Helmer Scientific, LLC.

Hefei's three-year grant acceleration

Hefei JEE Power Systems Co., Ltd. shows 6 grants in 2022–2024 against only 1 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.
