What this shows Ningbo's Innovation Score is 31.7/100 (38th 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 Ningbo?

Each dot is one of Ningbo’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). Ningbo’s own 13.5 claims/patent is ABOVE the 8.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ningbo's grants concentrate

Ningbo Weie Electronics Technology Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 94.4% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2019 (6 grants) versus a trough of 2 in 2018. By volume, Ningbo sits between NEC Network and Sensor Systems, Ltd. and Nitoms, Inc..

Ningbo's three-year grant acceleration

Ningbo Weie Electronics Technology Ltd. shows 3 grants in 2022–2024 against only 12 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.
