What this shows Daisen's Innovation Score is 20.6/100 (7th 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 Daisen?

Each dot is one of Daisen’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). Daisen’s own 4.6 claims/patent is at or below the 9.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daisen's grants concentrate

Daisen Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 80% 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 2016 (2 grants) versus a trough of 1 in 2017. By volume, Daisen sits between Daewon Industry Company and Dalian Czur Tech Co., Ltd.

Daisen's three-year grant acceleration

Daisen Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
