What this shows IHI's Innovation Score is 33.5/100 (45th percentile 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 8.7 claims/patent is at or below the 12.6 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 Charging Systems International GmbH is a focused PatentsView assignee: 14 CPC subclasses with 84.8% of grants classified under F05D (Indexing Scheme FOR Aspects Relating TO Non-positive-displacement Machines OR Engines, Gas-turbines OR Jet-propulsion Plants). Peak complete grant year is 2021 (9 grants) versus a trough of 1 in 2016. By volume, IHI sits between Hefei Core Storage Electronic Limited and Indian Wells Medical, Inc..

IHI's three-year grant acceleration

IHI Charging Systems International GmbH shows 6 grants in 2022–2024 against only 14 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.
