What this shows Cosmo's Innovation Score is 43.6/100 (top 28% 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 Cosmo?

Each dot is one of Cosmo’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). Cosmo’s own 12.3 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cosmo's grants concentrate

Cosmo Koki Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2017. By volume, Cosmo sits between Conway Electric, LLC and CP Studios LLC.

Cosmo's three-year grant acceleration

Cosmo Koki Co., Ltd. shows 5 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.
