What this shows Nippon's Innovation Score is 37.7/100 (top 43% 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 Nippon?

Each dot is one of Nippon’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). Nippon’s own 6.6 claims/patent is ABOVE the 6.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nippon's grants concentrate

Nippon Paint Surf Chemicals Co., Ltd is a focused PatentsView assignee: 17 CPC subclasses with 61.5% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2016. By volume, Nippon sits between Ningbo Ergovida Health Technology Ltd. and Noda Screen Co., Ltd..

Nippon's three-year grant acceleration

Nippon Paint Surf Chemicals Co., Ltd shows 3 grants in 2022–2024 against only 2 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.
