What this shows Kyoritsu's Innovation Score is 40.7/100 (top 35% 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 Kyoritsu?

Each dot is one of Kyoritsu’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). Kyoritsu’s own 16.6 claims/patent is ABOVE the 14.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kyoritsu's grants concentrate

Kyoritsu Chemical & Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 60% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2018. By volume, Kyoritsu sits between Kronos Bio, Inc. and Lamiflex AB.

Kyoritsu's three-year grant acceleration

Kyoritsu Chemical & Co., Ltd. shows 1 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.
