Portfolio overview

The Kansai Electric Power Co., Inc. has been granted 33 US utility patents between 2015 and 2025, placing The Kansai Electric Power Co., Inc. at rank #9,650 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.7 claims per patent with primary concentration in Y02C (CAPTURE, STORAGE, SEQUESTRATION OR DISPOSAL OF GREENHOUSE GASES [GHG]). As a Foreign Corporation, The Kansai Electric Power Co., Inc. is one of the more focused assignees in the PatentsView dataset. By volume, The sits between Textron Systems Corporation (33 patents, rank #9,646) and Truth Hardware Corporation (33 patents, rank #9,654) - the closest US assignees by grant volume. The composite Innovation Score of 45.7/100 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 9 grants, compared with 24 in the 2015–2019 window, a -62% 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. The Kansai Electric Power Co., Inc.'s 7.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark The Kansai Electric Power Co., Inc. against peers pursuing similar technology classes.
