Does more volume mean deeper claims for Okamoto?

Each dot is one of Okamoto’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). Okamoto’s own 6.3 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 Okamoto's grants concentrate

Okamoto Machine Tool Works, Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 90% of grants classified under B24B (Machines, Devices, OR Processes FOR Grinding OR Polishing ; Dressing OR Conditioning OF Abrading SURFACES; Feeding OF Grinding, Polishing, OR Lapping Agents). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, Okamoto sits between Ocme S.R.L. and Omni Consumer Products, LLC.

Okamoto's three-year grant acceleration

Okamoto Machine Tool Works, Ltd. shows 5 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.
