Does more volume mean deeper claims for Okuno?

Each dot is one of Okuno’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). Okuno’s own 14.0 claims/patent is ABOVE the 13.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Okuno's grants concentrate

Okuno Chemical Industries Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 90% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2017. By volume, Okuno sits between Ocunexus Therapeutics, Inc. and Omnivision Technologies (SHANGHAI) Co., Ltd..

Okuno's three-year grant acceleration

Okuno Chemical Industries Co., Ltd. shows 2 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.
