Portfolio overview

TOKYO ELECTRIC POWER COMPANY HOLDINGS, INCORPORATED has been granted 27 US utility patents between 2015 and 2025, placing TOKYO ELECTRIC POWER COMPANY HOLDINGS, INCORPORATED at rank #11,468 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 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, TOKYO ELECTRIC POWER COMPANY HOLDINGS, INCORPORATED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 41.5/100 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 14 grants, compared with 13 in the 2015–2019 window, a +8% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. TOKYO ELECTRIC POWER COMPANY HOLDINGS, INCORPORATED's 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TOKYO ELECTRIC POWER COMPANY HOLDINGS, INCORPORATED against peers pursuing similar technology classes.
