What this shows Krosakiharima's Innovation Score is 37.0/100 (top 45% 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 Krosakiharima?

Each dot is one of Krosakiharima’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). Krosakiharima’s own 9.4 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Krosakiharima's grants concentrate

Krosakiharima Corporation is a focused PatentsView assignee: 13 CPC subclasses with 70.3% of grants classified under B22D (Casting OF METALS; Casting OF Other Substances BY THE Same Processes OR Devices). Peak complete grant year is 2017 (6 grants) versus a trough of 1 in 2016. By volume, Krosakiharima sits between Kaltenbach & Voigt GMBH and Khalifa University of Science, Technology and Research.

Krosakiharima's three-year grant acceleration

Krosakiharima Corporation shows 10 grants in 2022–2024 against only 11 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.
