What this shows Nippon's Innovation Score is 42.5/100 (top 30% 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 13.1 claims/patent is ABOVE the 11.6 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 Yttrium Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 88.9% 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 2022 (2 grants) versus a trough of 1 in 2016. By volume, Nippon sits between Ningxia Orient Tantalum Industry Co., Ltd and Norbrook Laboratories Limited.

Nippon's three-year grant acceleration

Nippon Yttrium Co., Ltd. shows 5 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.
