Portfolio overview
NIPPON STEEL CHEMICAL & MATERIAL CO., LTD. has been granted 119 US utility patents between 2019 and 2025, placing NIPPON STEEL CHEMICAL & MATERIAL CO., LTD. at rank #3,159 across all assignees tracked by PlainPatent. This portfolio spans 60 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, NIPPON STEEL CHEMICAL & MATERIAL CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 52.9/100 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 94 grants, compared with 25 in the 2015–2019 window — a +276% 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. NIPPON STEEL CHEMICAL & MATERIAL CO., LTD.'s 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 60 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NIPPON STEEL CHEMICAL & MATERIAL CO., LTD. against peers pursuing similar technology classes.
