What this shows Kansai's Innovation Score is 38.7/100 (top 40% 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 Kansai?

Each dot is one of Kansai’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). Kansai’s own 6.9 claims/patent is at or below the 10.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kansai's grants concentrate

Kansai Coke AND Chemicals Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 50% of grants classified under C01P (Indexing Scheme Relating TO Structural AND Physical Aspects OF Solid Inorganic Compounds). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Kansai sits between Kaia Health Software GMBH and Kautex Maschinenbau GMBH.

Kansai's three-year grant acceleration

Kansai Coke AND Chemicals Co., Ltd. shows 2 grants in 2022–2024 against only 0 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.
