What this shows Ningbo's Innovation Score is 51.8/100 (top 11% 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 Ningbo's grants concentrate

Ningbo Sanhan Alloy Material Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 40% of grants classified under Y02P (Climate Change Mitigation Technologies IN THE Production OR Processing OF Goods). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2022. By volume, Ningbo sits between Nice North America LLC and Nordic Lights Oy.

Ningbo's three-year grant acceleration

Ningbo Sanhan Alloy Material Co., Ltd. shows 9 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.
