Portfolio overview

State GRID Zhejiang Electric Power Co., Ltd has been granted 7 US utility patents between 2019 and 2025, placing State GRID Zhejiang Electric Power Co., Ltd at rank #37,484 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 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, State GRID Zhejiang Electric Power Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, State sits between ST&T International, Inc. (7 patents, rank #37,480) and Stella Mccartney Limited (7 patents, rank #37,488) - the closest US assignees by grant volume. The composite Innovation Score of 31.5/100 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 6 grants, compared with 1 in the 2015–2019 window, a +500% 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. State GRID Zhejiang Electric Power Co., Ltd's 10.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark State GRID Zhejiang Electric Power Co., Ltd against peers pursuing similar technology classes.
