Portfolio overview

Korea Hydro & Nuclear Power Co., Ltd. has been granted 116 US utility patents between 2015 and 2025, placing Korea Hydro & Nuclear Power Co., Ltd. at rank #3,231 across all assignees tracked by PlainPatent. This portfolio spans 74 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.5 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 Hydro & Nuclear Power Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Korea sits between Hach Company (116 patents, rank #3,227) and Macau University Of Science And Technology (116 patents, rank #3,235) - the closest US assignees by grant volume. The composite Innovation Score of 58.1/100 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 59 grants, compared with 57 in the 2015–2019 window, a +4% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Hydro & Nuclear Power Co., Ltd.'s 7.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 74 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Hydro & Nuclear Power Co., Ltd. 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.
