Portfolio overview

Japan Science And Technology Agency has been granted 388 US utility patents between 2015 and 2025, placing Japan Science And Technology Agency at rank #1,100 across all assignees tracked by PlainPatent. This portfolio spans 156 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.1 claims per patent with primary concentration in H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES). As a Foreign Corporation, Japan Science And Technology Agency is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Japan sits between KYB Corporation (389 patents, rank #1,096) and Infinera Corp. (386 patents, rank #1,104) - the closest US assignees by grant volume. The composite Innovation Score of 57.1/100 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 150 grants, compared with 238 in the 2015–2019 window, a -37% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Japan Science And Technology Agency's 12.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 Japan Science And Technology Agency against peers pursuing similar technology classes.

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.
