What this shows Nitto's Innovation Score is 41.3/100 (top 33% 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 Nitto?

Each dot is one of Nitto’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). Nitto’s own 7.9 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nitto's grants concentrate

Nitto Kohki Co., Ltd. is a focused PatentsView assignee: 31 CPC subclasses with 36.4% 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 2021 (8 grants) versus a trough of 2 in 2015. By volume, Nitto sits between Morgan State University and Omni United (S) PTE Ltd.

Nitto's three-year grant acceleration

Nitto Kohki Co., Ltd. shows 10 grants in 2022–2024 against only 18 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.
