What this shows IHI's Innovation Score is 45.4/100 (top 23% 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 IHI?

Each dot is one of IHI’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). IHI’s own 7.6 claims/patent is at or below the 8.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where IHI's grants concentrate

IHI Inspection AND Instrumentation Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 61.5% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2016. By volume, IHI sits between ID Development Limited and Industriale Chimica S.R.L..

IHI's three-year grant acceleration

IHI Inspection AND Instrumentation Co., Ltd. shows 6 grants in 2022–2024 against only 2 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.
