What this shows Ningbo's Innovation Score is 39.7/100 (top 37% 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 9.8 claims/patent is ABOVE the 2.0 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 Lumilan Advanced Materials Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under H10K (Organic Electric Solid-state Devices). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Ningbo sits between Ningbo Gaoli Electronic Technology Co., Ltd. and Nippoh Chemicals Co., Ltd..

Ningbo's three-year grant acceleration

Ningbo Lumilan Advanced Materials Co., Ltd. shows 5 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.
