What this shows Kongju's Innovation Score is 54.5/100 (top 8% 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 Kongju?

Each dot is one of Kongju’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). Kongju’s own 8.9 claims/patent is at or below the 10.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kongju's grants concentrate

Kongju National University Industry-university Cooperation Foundation is a focused PatentsView assignee: 34 CPC subclasses with 27.3% of grants classified under C03C (Chemical Composition OF Glasses, Glazes OR Vitreous ENAMELS; Surface Treatment OF GLASS; Surface Treatment OF Fibres OR Filaments Made From Glass, Minerals OR SLAGS; Joining Glass TO Glass OR Other MA). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2015. By volume, Kongju sits between Know Systems Corp and Korea Resources Corporation.

Kongju's three-year grant acceleration

Kongju National University Industry-university Cooperation Foundation shows 5 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.
