AICHI STEEL CORPORATION

AICHI STEEL CORPORATION has been granted 98 US utility patents between 2015 and 2025, placing AICHI STEEL CORPORATION at rank #3,695 across all assignees tracked by PlainPatent. This portfolio spans 66 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.5 claims per patent with primary concentration in G08G (TRAFFIC CONTROL SYSTEMS). As a Foreign Corporation, AICHI STEEL CORPORATION is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 54.9/100 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 75 grants, compared with 23 in the 2015–2019 window — a +226% 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. AICHI STEEL CORPORATION's 12.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 66 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AICHI STEEL CORPORATION against peers pursuing similar technology classes.
