Portfolio overview

Korea Fuel-tech Corporation has been granted 11 US utility patents between 2017 and 2025, placing Korea Fuel-tech Corporation at rank #24,638 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in B60K (ARRANGEMENT OR MOUNTING OF PROPULSION UNITS OR OF TRANSMISSIONS IN VEHICLES; ARRANGEMENT OR MOUNTING OF PLURAL DIVERSE PRIME-MOVERS IN VEHICLES; AUXILIARY DRIVES FOR VEHICLES; INSTRUMENTATION OR DASHB). As a Foreign Corporation, Korea Fuel-tech Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Korea sits between Komico Ltd. (11 patents, rank #24,634) and KOYO Machine Industries Co., Ltd. (11 patents, rank #24,642) - the closest US assignees by grant volume. The composite Innovation Score of 49.9/100 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. Korea Fuel-tech Corporation's 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Fuel-tech Corporation against peers pursuing similar technology classes.
