What this shows Nihon's Innovation Score is 44.2/100 (top 26% 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 Nihon?

Each dot is one of Nihon’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). Nihon’s own 9.7 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nihon's grants concentrate

Nihon Parkerizing Co., Ltd. is a focused PatentsView assignee: 30 CPC subclasses with 69% 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 2020 (5 grants) versus a trough of 1 in 2016. By volume, Nihon sits between Natural Extraction Systems, LLC and Nubis Communications, Inc..

Nihon's three-year grant acceleration

Nihon Parkerizing Co., Ltd. shows 11 grants in 2022–2024 against only 10 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.
