What this shows Ohara's Innovation Score is 43.5/100 (top 28% 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 Ohara?

Each dot is one of Ohara’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). Ohara’s own 10.4 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ohara's grants concentrate

Ohara Inc. is a focused PatentsView assignee: 20 CPC subclasses with 64.7% of grants classified under C03C (Chemical Composition OF Glasses, Glazes OR Vitreous ENAMELS; Surface Treatment OF GLASS; Surface Treatment OF Fibres OR Filaments Made From Glass, Minerals OR SLAGS; Joining Glass TO Glass OR Other MA). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2017. By volume, Ohara sits between NL Giken Incorporated and P2 Science Inc..

Ohara's three-year grant acceleration

Ohara Inc. shows 11 grants in 2022–2024 against only 8 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.
