Portfolio overview

Electric Power Science & Research Institute Of State Grid Tianjin Electric Power Company has been granted 13 US utility patents between 2021 and 2025, placing Electric Power Science & Research Institute Of State Grid Tianjin Electric Power Company at rank #21,080 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a Foreign Corporation, Electric Power Science & Research Institute Of State Grid Tianjin Electric Power Company is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 50.3/100 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 2021 through 2025, with 13 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. Electric Power Science & Research Institute Of State Grid Tianjin Electric Power Company's 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Electric Power Science & Research Institute Of State Grid Tianjin Electric Power Company against peers pursuing similar technology classes.
