Portfolio overview

Japan Aerospace Exploration Agency has been granted 139 US utility patents between 2015 and 2025, placing Japan Aerospace Exploration Agency at rank #2,772 across all assignees tracked by PlainPatent. This portfolio spans 113 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in B64C (AEROPLANES; HELICOPTERS). As a Foreign Corporation, Japan Aerospace Exploration Agency is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Japan sits between Cytiva Sweden AB (139 patents, rank #2,768) and Nuovo Pignone Tecnologie S.r.l. (139 patents, rank #2,776) - the closest US assignees by grant volume. The composite Innovation Score of 58.4/100 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 101 grants, compared with 38 in the 2015–2019 window, a +166% 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. Japan Aerospace Exploration Agency's 9.9 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 Japan Aerospace Exploration Agency against peers pursuing similar technology classes.
