Portfolio overview
K-MARINE CO., LTD. has been granted 6 US utility patents between 2023 and 2025, placing K-MARINE CO., LTD. at rank #41,131 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.2 claims per patent with primary concentration in B63B (SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING). As a Foreign Corporation, K-MARINE CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 40.4/100 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. Historical data spans 2023 through 2025, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. K-MARINE CO., LTD.'s 4.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark K-MARINE CO., LTD. against peers pursuing similar technology classes.
