What this shows Nisshin's Innovation Score is 38.5/100 (top 40% 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 6.5 claims/patent is at or below the 17.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nisshin's grants concentrate

Nisshin Engineering Inc. is a focused PatentsView assignee: 21 CPC subclasses with 40% of grants classified under B22F (Working Metallic POWDER; Manufacture OF Articles From Metallic POWDER; Making Metallic Powder ; Apparatus OR Devices Specially Adapted FOR Metallic Powder). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2016. By volume, Nisshin sits between Nileworks Inc. and Nxt-id, Inc..

Nisshin's three-year grant acceleration

Nisshin Engineering Inc. shows 4 grants in 2022–2024 against only 3 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.
