What this shows Kobelco's Innovation Score is 25.3/100 (17th percentile 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 Kobelco?

Each dot is one of Kobelco’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). Kobelco’s own 4.6 claims/patent is at or below the 9.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kobelco's grants concentrate

Kobelco Eco-solutions Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 37.5% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2015. By volume, Kobelco sits between Kinreen Technology (SHENZHEN) Co., Ltd. and Konrad GMBH.

Kobelco's three-year grant acceleration

Kobelco Eco-solutions Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
