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.
