Portfolio overview

Tokyo Institute Of Technology has been granted 322 US utility patents between 2015 and 2025, placing Tokyo Institute Of Technology at rank #1,320 across all assignees tracked by PlainPatent. This portfolio spans 181 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 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 Institute Of Technology is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Tokyo sits between Verisign, Inc. (323 patents, rank #1,316) and Southeast University (320 patents, rank #1,324) - the closest US assignees by grant volume. The composite Innovation Score of 59.1/100 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 167 grants, compared with 155 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 Institute Of Technology's 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tokyo Institute Of Technology against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
