What this shows Nanhu's Innovation Score is 44.6/100 (top 25% 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 Nanhu?

Each dot is one of Nanhu’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). Nanhu’s own 11.5 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nanhu's grants concentrate

Nanhu Laboratory is a focused PatentsView assignee: 6 CPC subclasses with 61.5% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (5 grants) versus a trough of 4 in 2023. By volume, Nanhu sits between Northwest Institute OF Eco-environment AND Resources, CAS and Natural Ocean Well Co..

Nanhu's three-year grant acceleration

Nanhu Laboratory 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.
