Portfolio overview

Korea Electric Power Corporation has been granted 98 US utility patents between 2015 and 2025, placing Korea Electric Power Corporation at rank #3,705 across all assignees tracked by PlainPatent. This portfolio spans 77 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a Foreign Corporation, Korea Electric Power Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Korea sits between FLIR Systems AB (98 patents, rank #3,701) and Pharmacyclics Llc (98 patents, rank #3,709) - the closest US assignees by grant volume. The composite Innovation Score of 50.6/100 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 38 grants, compared with 60 in the 2015–2019 window, a -37% 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 Electric Power Corporation's 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 77 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Electric Power Corporation against peers pursuing similar technology classes.

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.
