What this shows Ishihara's Innovation Score is 50.9/100 (top 12% 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 Ishihara?

Each dot is one of Ishihara’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). Ishihara’s own 11.1 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ishihara's grants concentrate

Ishihara Sangyo Kaisha, Ltd. is a focused PatentsView assignee: 42 CPC subclasses with 55.2% of grants classified under A01N (Preservation OF Bodies OF Humans OR Animals OR Plants OR Parts Thereof ; Biocides, e.g. AS Disinfectants, AS Pesticides OR AS Herbicides ; Pest Repellants OR ATTRACTANTS; Plant Growth Regulators). Peak complete grant year is 2017 (15 grants) versus a trough of 3 in 2023. By volume, Ishihara sits between F-Secure Corporation and MobiTV, Inc..

Ishihara's three-year grant acceleration

Ishihara Sangyo Kaisha, Ltd. shows 15 grants in 2022–2024 against only 17 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.
