Portfolio overview

Kyushu Electric Power Co., Inc. has been granted 10 US utility patents between 2015 and 2022, placing Kyushu Electric Power Co., Inc. at rank #26,683 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 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, Kyushu Electric Power Co., Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Kyushu sits between KS Gleitlager Gmbh (10 patents, rank #26,679) and Katco Holdings Pty Ltd (10 patents, rank #26,687) - the closest US assignees by grant volume. The composite Innovation Score of 34.7/100 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 1 grants, compared with 9 in the 2015–2019 window, a -89% 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. Kyushu Electric Power Co., Inc.'s 7.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kyushu Electric Power Co., Inc. 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.
