The verdict
Tatsuno holds 57 US patents across 29 technology areas, rank #5,979 of 50,000 tracked assignees.
Tatsuno Corporation has been granted 57 US utility patents between 2016 and 2025, placing Tatsuno Corporation at rank #5,979 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.3 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, Tatsuno Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Tatsuno sits between Robin Systems, Inc. (57 patents, rank #5,975) and The Eastern Company (57 patents, rank #5,983) - the closest US assignees by grant volume. The composite Innovation Score of 42.2/100 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 38 grants, compared with 19 in the 2015–2019 window, a +100% 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. Tatsuno Corporation's 6.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tatsuno Corporation against peers pursuing similar technology classes.

How to use this portfolio
Tatsuno's 57 grants land it in the top 31% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
