ThyssenKrupp Steel Europe AG

ThyssenKrupp Steel Europe AG has been granted 219 US utility patents between 2015 and 2025, placing ThyssenKrupp Steel Europe AG at rank #1,843 across all assignees tracked by PlainPatent. This portfolio spans 80 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.2 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, ThyssenKrupp Steel Europe AG is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 53.3/100 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 76 grants, compared with 143 in the 2015–2019 window — a -47% 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. ThyssenKrupp Steel Europe AG's 13.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 80 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ThyssenKrupp Steel Europe AG against peers pursuing similar technology classes.
