Portfolio overview

Kongju National University Industry-university Cooperation Foundation has been granted 11 US utility patents between 2015 and 2025, placing Kongju National University Industry-university Cooperation Foundation at rank #24,635 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 claims per patent with primary concentration in 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). As a Foreign Corporation, Kongju National University Industry-university Cooperation Foundation is one of the more focused assignees in the PatentsView dataset. By volume, Kongju sits between KNOW Systems Corp (11 patents, rank #24,631) and Korea Resources Corporation (11 patents, rank #24,639) - the closest US assignees by grant volume. The composite Innovation Score of 54.5/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 7 grants, compared with 4 in the 2015–2019 window, a +75% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Kongju National University Industry-university Cooperation Foundation's 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kongju National University Industry-university Cooperation Foundation against peers pursuing similar technology classes.
