What this shows Daemo'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 Daemo?

Each dot is one of Daemo’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). Daemo’s own 12.6 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Daemo's grants concentrate

Daemo Engineering Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under E02F (DREDGING; Soil-shifting). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2018. By volume, Daemo sits between D&B Business Information Solutions and Dainihon Jochugiku Co., Ltd..

Daemo's three-year grant acceleration

Daemo Engineering 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.
