Portfolio overview
BAOSHAN IRON & STEEL CO., LTD. has been granted 193 US utility patents between 2015 and 2025, placing BAOSHAN IRON & STEEL CO., LTD. at rank #2,053 across all assignees tracked by PlainPatent. This portfolio spans 78 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in C21D (MODIFYING THE PHYSICAL STRUCTURE OF FERROUS METALS; GENERAL DEVICES FOR HEAT TREATMENT OF FERROUS OR NON-FERROUS METALS OR ALLOYS; MAKING METAL MALLEABLE, e.g. BY DECARBURISATION OR TEMPERING). As a Foreign Corporation, BAOSHAN IRON & STEEL CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 57.0/100 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 128 grants, compared with 65 in the 2015–2019 window — a +97% 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. BAOSHAN IRON & STEEL CO., LTD.'s 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 78 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark BAOSHAN IRON & STEEL CO., LTD. against peers pursuing similar technology classes.
