What this shows Kyoeisha's Innovation Score is 42.5/100 (top 30% 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 Kyoeisha?

Each dot is one of Kyoeisha’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). Kyoeisha’s own 15.3 claims/patent is ABOVE the 8.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kyoeisha's grants concentrate

Kyoeisha Chemical Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 62.5% of grants classified under C08F (Macromolecular Compounds Obtained BY Reactions Only Involving Carbon-to-carbon Unsaturated Bonds). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Kyoeisha sits between Kwantex Research Inc. and Kaetel Systems GmbH.

Kyoeisha's three-year grant acceleration

Kyoeisha Chemical Co., Ltd. shows 3 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.
