Portfolio overview

China Three Gorges Corporation has been granted 23 US utility patents between 2023 and 2025, placing China Three Gorges Corporation at #12,866 of 50,000 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. By volume, China sits between Capsum (23 patents, rank #12,854) and Cockerill Maintenance & Ingenierie S.a. (23 patents, rank #12,862) - the closest US assignees by grant volume. The composite Innovation Score of 58.4/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2023 through 2025, with 23 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. China Three Gorges Corporation's 8.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 40 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
