Portfolio overview
Voestalpine Stahl GmbH has been granted 56 US utility patents between 2015 and 2025, placing Voestalpine Stahl GmbH at rank #6,091 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.1 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, Voestalpine Stahl GmbH is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 50.5/100 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 31 grants, compared with 25 in the 2015–2019 window — a +24% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Voestalpine Stahl GmbH's 14.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Voestalpine Stahl GmbH against peers pursuing similar technology classes.
