Portfolio overview

North China Electrical Power University has been granted 91 US utility patents between 2015 and 2025, placing North China Electrical Power University at rank #3,978 across all assignees tracked by PlainPatent. This portfolio spans 57 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.2 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, North China Electrical Power University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, North sits between Kistler Holding Ag (91 patents, rank #3,974) and Suzhou Opple Lighting Co., Ltd. (91 patents, rank #3,982) - the closest US assignees by grant volume. The composite Innovation Score of 57.9/100 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 80 grants, compared with 11 in the 2015–2019 window, a +627% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. North China Electrical Power University's 6.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 57 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark North China Electrical Power University against peers pursuing similar technology classes.
