What this shows Kanagawa's Innovation Score is 43.1/100 (top 29% 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 Kanagawa?

Each dot is one of Kanagawa’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). Kanagawa’s own 9.5 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kanagawa's grants concentrate

Kanagawa Institute OF Industrial Science AND Technology is a focused PatentsView assignee: 30 CPC subclasses with 29.4% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2019. By volume, Kanagawa sits between Jace Medical, LLC and Kimoto Co., Ltd..

Kanagawa's three-year grant acceleration

Kanagawa Institute OF Industrial Science AND Technology shows 6 grants in 2022–2024 against only 5 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.
