What this shows Konoshima's Innovation Score is 34.2/100 (47th 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 Konoshima?

Each dot is one of Konoshima’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). Konoshima’s own 7.6 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Konoshima's grants concentrate

Konoshima Chemical Co., Ltd. is a focused PatentsView assignee: 23 CPC subclasses with 70% of grants classified under C01F (Compounds OF THE Metals Beryllium, Magnesium, Aluminium, Calcium, Strontium, Barium, Radium, Thorium, OR OF THE Rare-earth Metals). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2017. By volume, Konoshima sits between Kogent Surgical, LLC and Krysse AS.

Konoshima's three-year grant acceleration

Konoshima Chemical Co., Ltd. shows 2 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.
