What this shows Dankook's Innovation Score is 38.9/100 (top 40% 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 Dankook?

Each dot is one of Dankook’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). Dankook’s own 10.9 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dankook's grants concentrate

Dankook University Cheonan Campus Industry Academic Cooperation Foundation is a focused PatentsView assignee: 29 CPC subclasses with 40% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2020. By volume, Dankook sits between Cyph, Inc. and Dexcel Pharma Technologies Ltd..

Dankook's three-year grant acceleration

Dankook University Cheonan Campus Industry Academic Cooperation Foundation shows 5 grants in 2022–2024 against only 9 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.
