What this shows Kurimoto's Innovation Score is 37.7/100 (top 43% 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 Kurimoto?

Each dot is one of Kurimoto’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). Kurimoto’s own 7.2 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kurimoto's grants concentrate

Kurimoto, Ltd. is a focused PatentsView assignee: 26 CPC subclasses with 35.3% of grants classified under C22C (Alloys). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, Kurimoto sits between Kionix, Inc. and Lantronix, Inc..

Kurimoto's three-year grant acceleration

Kurimoto, Ltd. shows 4 grants in 2022–2024 against only 5 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.
