What this shows Yamazaki's Innovation Score is 55.5/100 (top 7% 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 Yamazaki?

Each dot is one of Yamazaki’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). Yamazaki’s own 15.5 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yamazaki's grants concentrate

Yamazaki Mazak Corporation is a focused PatentsView assignee: 32 CPC subclasses with 71.4% 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 2024 (11 grants) versus a trough of 2 in 2018. By volume, Yamazaki sits between W&H Dentalwerk Bürmoos GmbH and AC Immune SA.

Yamazaki's three-year grant acceleration

Yamazaki Mazak Corporation shows 19 grants in 2022–2024 against only 10 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.
