Portfolio overview

Korea Institute OF Energy Research has been granted 322 US utility patents between 2015 and 2025, placing Korea Institute OF Energy Research at rank #1,317 across all assignees tracked by PlainPatent. This portfolio spans 143 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Korea Institute OF Energy Research is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Korea sits between Rosemount Inc. (323 patents, rank #1,313) and Coplus Inc. (321 patents, rank #1,321) - the closest US assignees by grant volume. The composite Innovation Score of 54.1/100 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 85 grants, compared with 237 in the 2015–2019 window, a -64% 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 Institute OF Energy Research's 10.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Institute OF Energy Research against peers pursuing similar technology classes.
