Portfolio overview

Korea Airports Corporation has been granted 21 US utility patents between 2016 and 2025, placing Korea Airports Corporation at rank #14,093 across all assignees tracked by PlainPatent. This portfolio spans 32 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 claims per patent with primary concentration in B64F (GROUND OR AIRCRAFT-CARRIER-DECK INSTALLATIONS SPECIALLY ADAPTED FOR USE IN CONNECTION WITH AIRCRAFT; DESIGNING, MANUFACTURING, ASSEMBLING, CLEANING, MAINTAINING OR REPAIRING AIRCRAFT, NOT OTHERWISE PR). As a Foreign Corporation, Korea Airports Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Korea sits between Kholle Magnolia 2015, Llc (21 patents, rank #14,089) and Keep Technologies, Inc. (21 patents, rank #14,097) - the closest US assignees by grant volume. The composite Innovation Score of 39.8/100 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 6 grants, compared with 15 in the 2015–2019 window, a -60% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Airports Corporation's 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 32 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Airports Corporation against peers pursuing similar technology classes.
