Portfolio overview

KOREA ELECTROTECHNOLOGY RESEARCH INSTITUTE has been granted 66 US utility patents between 2015 and 2025, placing KOREA ELECTROTECHNOLOGY RESEARCH INSTITUTE at rank #5,219 across all assignees tracked by PlainPatent. This portfolio spans 60 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 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 ELECTROTECHNOLOGY RESEARCH INSTITUTE is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 52.5/100 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 25 grants, compared with 41 in the 2015–2019 window — a -39% 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 ELECTROTECHNOLOGY RESEARCH INSTITUTE's 15.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 60 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KOREA ELECTROTECHNOLOGY RESEARCH INSTITUTE against peers pursuing similar technology classes.

How to use this portfolio

Korea's 66 grants land it in the top 10% by Innovation Score — but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance — Korea ranks #5,219 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y02E — see who else leads that technology area. Y02E leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity — not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
