What this shows Nichirin's Innovation Score is 31.2/100 (37th percentile 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 Nichirin?

Each dot is one of Nichirin’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). Nichirin’s own 5.4 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nichirin's grants concentrate

Nichirin Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 87.5% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Nichirin sits between Next Jump, Inc. and Nintex USA, Inc..

Nichirin's three-year grant acceleration

Nichirin Co., Ltd. shows 3 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.
