What this shows Hangzhou's Innovation Score is 45.2/100 (top 24% 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 Hangzhou's grants concentrate

Hangzhou Leaderway Electronics Co., Ltd is a focused PatentsView assignee: 6 CPC subclasses with 66.7% of grants classified under H02P (Control OR Regulation OF Electric Motors, Electric Generators OR Dynamo-electric CONVERTERS; Controlling Transformers, Reactors OR Choke Coils). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2016. By volume, Hangzhou sits between Hancock Medical, Inc. and Hangzhou Santan Medical Technology Co., Ltd.

Hangzhou's three-year grant acceleration

Hangzhou Leaderway Electronics Co., Ltd shows 3 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.
