Portfolio overview

TOYO Aluminium Kabushiki Kaisha has been granted 52 US utility patents between 2015 and 2025, placing TOYO Aluminium Kabushiki Kaisha at rank #6,491 across all assignees tracked by PlainPatent. This portfolio spans 58 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.1 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, TOYO Aluminium Kabushiki Kaisha is one of the broader-portfolio assignees in the PatentsView dataset. By volume, TOYO sits between Sun Hydraulics, Llc (52 patents, rank #6,487) and The University Of Nottingham (52 patents, rank #6,495) - the closest US assignees by grant volume. The composite Innovation Score of 50.2/100 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 20 grants, compared with 32 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. TOYO Aluminium Kabushiki Kaisha's 8.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 58 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TOYO Aluminium Kabushiki Kaisha against peers pursuing similar technology classes.
