Portfolio overview
CHINA THREE GORGES CORPORATION has been granted 23 US utility patents between 2023 and 2025, placing CHINA THREE GORGES CORPORATION at rank #12,858 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 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, CHINA THREE GORGES CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 58.4/100 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. Historical data spans 2023 through 2025, with 23 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 CORPORATION's 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 40 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CHINA THREE GORGES CORPORATION against peers pursuing similar technology classes.
