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.
