What this shows Nisshin's Innovation Score is 37.4/100 (top 44% 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 Nisshin?

Each dot is one of Nisshin’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). Nisshin’s own 8.8 claims/patent is ABOVE the 6.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nisshin's grants concentrate

Nisshin Seifun Group Inc. is a focused PatentsView assignee: 25 CPC subclasses with 29.2% of grants classified under B07B (Separating Solids From Solids BY Sieving, Screening, Sifting OR BY Using GAS CURRENTS; Separating BY Other DRY Methods Applicable TO Bulk Material, e.g. Loose Articles FIT TO BE Handled Like Bulk Mate). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2020. By volume, Nisshin sits between NEWTL and NS Materials Inc..

Nisshin's three-year grant acceleration

Nisshin Seifun Group Inc. shows 3 grants in 2022–2024 against only 6 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.
