What this shows Komatsu's Innovation Score is 44.0/100 (top 27% 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 Komatsu?

Each dot is one of Komatsu’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). Komatsu’s own 6.6 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Komatsu's grants concentrate

Komatsu NTC Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 50% of grants classified under B23Q (Details, Components, OR Accessories FOR Machine Tools, e.g. Arrangements FOR Copying OR Controlling ; Machine Tools IN General Characterised BY THE Construction OF Particular Details OR COMPONENTS; Co). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2020. By volume, Komatsu sits between Kitz SCT Corporation and Korea Meteorological Administration.

Komatsu's three-year grant acceleration

Komatsu NTC Ltd. shows 6 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.
