Portfolio overview

Korea Maritime University Industry—academic Cooperation Foundation has been granted 8 US utility patents between 2019 and 2025, placing Korea Maritime University Industry—academic Cooperation Foundation at rank #32,235 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a Foreign Corporation, Korea Maritime University Industry—academic Cooperation Foundation is one of the more focused assignees in the PatentsView dataset. By volume, Korea sits between Kontrolfreek, Llc (8 patents, rank #32,231) and Kuching International Ltd. (8 patents, rank #32,239) - the closest US assignees by grant volume. The composite Innovation Score of 36.3/100 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 1 in the 2015–2019 window, a +600% 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. Korea Maritime University Industry—academic Cooperation Foundation's 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Maritime University Industry—academic Cooperation Foundation against peers pursuing similar technology classes.
