Portfolio overview

China Three Gorges University has been granted 7 US utility patents between 2016 and 2025, placing China Three Gorges University at rank #34,676 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in Y02A (TECHNOLOGIES FOR ADAPTATION TO CLIMATE CHANGE). As a Foreign Corporation, China Three Gorges University is one of the more focused assignees in the PatentsView dataset. By volume, China sits between Chengdu Sioeye Technology Co., Ltd. (7 patents, rank #34,672) and Chosen Co., Ltd. (7 patents, rank #34,680) - the closest US assignees by grant volume. The composite Innovation Score of 45.5/100 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 5 grants, compared with 2 in the 2015–2019 window, a +150% 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. China Three Gorges University's 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark China Three Gorges University against peers pursuing similar technology classes.
