ArcelorMittal S.A., commonly known as ArcelorMittal, is a multinational steel manufacturing and mining corporation headquartered in Luxembourg City, Luxembourg. Formed in 2006 from the acquisition of Arcelor by Mittal Steel Company (which itself was founded in 1976), it is a publicly traded company with its shares listed on exchanges including Euronext Amsterdam and NYSE under the ticker MT. The Mittal family remains the largest shareholder, holding approximately two-fifths of the company. As of 2024, ArcelorMittal reported revenues of $62.44 billion and had approximately 125,416 employees globally. Its market capitalization was around $49.69 billion in fiscal year 2024.
ArcelorMittal operates as a vertically integrated steel and mining company, managing the entire steel production process from mining raw materials to manufacturing finished goods. Its primary products include flat steel (e.g., hot and cold rolled coils, coated sheets), long steel (e.g., I-beams, bars, rods, structural shapes, wire products, rails), and tubular products. These steel products serve a wide range of industries, including automotive, construction, household appliances, packaging, and engineering. The company also engages in significant iron ore and coal mining operations across multiple continents. ArcelorMittal actively invests in research and development, focusing on advanced high-strength steels for automotive applications and developing "smarter steels" and decarbonization solutions under its XCarb brand.
In terms of patent litigation, ArcelorMittal demonstrates a posture of actively asserting its intellectual property. The company has appeared as a plaintiff in one tracked case and as a defendant in zero cases. This pattern suggests it is an operating company enforcing its patent rights rather than a non-practicing entity (NPE) or primarily a defendant against patent assertions.
The sole tracked case involving ArcelorMittal is ArcelorMittal of Luxembourg v. VinFast Auto Ltd. of Hai Phong City, Vietnam et al., filed on April 17, 2024, in the U.S. International Trade Commission (ITC). This case indicates ArcelorMittal is utilizing the ITC, a venue known for addressing disputes involving imported goods, to protect its patent interests.
