Portfolio overview

TOYO TANSO CO., LTD. has been granted 52 US utility patents between 2015 and 2024, placing TOYO TANSO CO., LTD. at rank #6,492 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in C01B (NON-METALLIC ELEMENTS; COMPOUNDS THEREOF; ; METALLOIDS OR COMPOUNDS THEREOF NOT COVERED BY SUBCLASS C01C). As a Foreign Corporation, TOYO TANSO CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 46.7/100 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 38 in the 2015–2019 window — a -63% 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. TOYO TANSO CO., LTD.'s 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TOYO TANSO CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio

TOYO's 52 grants land it in the top 20% by Innovation Score — but volume alone doesn't tell you where the strength sits.
